Natural stone and artificial stone

1. Natural stone Natural stone is mainly divided into two types: marble and granite. In general, all textures are called "marble"; spots are mainly called "granite." This is in a broad sense. In a narrow sense, marble refers to the stone produced in Dali, Yunnan. In fact, there are not many stones in all parts of the country. Both can also be distinguished from geological concepts. Granite is a igneous rock, also called acid crystal deep diagenetic rock. It is the most widely distributed type of rock in igneous rock. It is composed of feldspar, quartz and mica, and the rock is hard and dense. Its composition is mainly silica, accounting for about 65%-75%. The so-called igneous rock is the rock formed by the underground magma or volcanic eruption of molten lava. The content of silica in the igneous rock, the nature of the feldspar, and its content determine the properties of the stone. When the content of silica is more than 65%, it belongs to acidic rock. In this type of rock, when the basic minerals such as orthoclase, plagioclase, and quartz form a crystal, they are in a material structure and are called granite. Marble is the metamorphic rock formed by the original rock in the crust through the high temperature and high pressure in the earth's crust. The internal force of the earth's crust promotes the qualitative change of all kinds of original rocks, ie the structure, structure and mineral composition of the original rock are changed. The new rock formed through qualitative change is called metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine and dolomite. Its main component is calcium carbonate, accounting for more than 50%. Because marble generally contains impurities, and calcium carbonate in the atmosphere by the role of carbon dioxide, carbides, water, but also easy to weathering and erosion, and make the surface lose luster quickly. The general nature of marble is relatively soft, which is relative to granite. Because the surface of natural stone has pores, it is relatively poor in stain resistance, and it is generally treated on the surface of a processing plant. In interior decoration, marble is suitable for use on TV stands, windowsills, and indoor floors. The threshold, cabinet countertops, and outdoor ground are suitable for granite. Which cabinet counter view is good is the use of dark granite. Nowadays, some of the natural stone that is sold on the market is processed by hand. These stones generally show their true appearance after being used for half a year to a year. It is obvious that the big greens on the market today are dyed and not the true primary colors. Another thing to note is the back grid. There are two situations where this happens: 1 The stone itself is relatively brittle and must be gridded, such as Spanish beige. 2 By cutting corners, the thickness of these stones was thinned and the strength was not enough, so the network was added. Generally, if the stone is darker in color, most of the reasons are. 2. Artificial stone Artificial stone is made of unsaturated polyester resin as binding agent, together with natural marble or inorganic powder such as calcite, silica sand, and glass powder, as well as suitable flame retardants, colors, etc. , porcelain casting, vibration compression, extrusion and other methods of forming and curing. Man-made stone is based on the actual use of natural stone, and it has made great progress in moisture-proof, acid-proof, high-temperature resistant and patchwork. Of course, man-made things naturally have artificial shortcomings. Man-made stones are naturally insufficient in nature, and textures are relatively false. Therefore, they are mostly used in places such as cabinets where practical requirements are high, and in some harsh environments such as kitchens, toilets, etc. Window-sills, floors, etc., emphasize decorative areas and are less used. Another factor that hinders the use of artificial stone is human factors. Because the manufacturing process of artificial stone is very different, performance and characteristics are not exactly the same, so the above mentioned advantages are not necessarily the performance of the artificial stone you have purchased. The artificial stone imported on the market at present is better in performance. For example, the imported marble allows sanding the scratches on the surface. The user will not be able to deal with it by himself. Many domestic artificial stones obviously cannot support this talent flow. The more polished, the worse. To buy artificial stone, it is best to take a sample plate for bad performance tests, such as pouring soy sauce or oil and carrying out caries testing. To sum up, what type of stone to buy is determined by the location, use, and individual economic capabilities.
Natural cultural stone and artificial culture stone

Culture stone used in home decoration originated abroad. Although China has long used a similar wall surface treatment. But it is generally used outdoors. In the early 1990s, the concept of cultural stone entered China, and the culture stone at that time was basically imported. The massive use of cultural stones was after 1999, when a large number of domestic and joint venture cultural stone manufacturers began to appear in the country. The market's competitive prices have dropped dramatically. Nowadays, a cheap culture stone can be purchased for around 100 yuan per square metre, and slightly better is around 300 yuan per square metre. What exactly is “cultural stone?” In simple words, cultural stone is a natural or man-made stone with a size of 400 mm×400 mm and a rough surface for indoor and outdoor use. “Specification size less than 400mm×400mm, rough surface” is Its main two features. Culture stone itself does not have a specific cultural connotation. However, cultural stone has a rough texture and natural form. It can be said that cultural stone is a reflection of people's return to nature and returning to their natural state of mind in interior decoration. This kind of mentality we also understand as a kind of living culture. 1. Natural culture stone Natural culture stone is a set of stone ore mined in nature. Among them, slate, sandstone, and quartz stone have been processed into a decorative building material. The natural culture stone material is hard, bright in color, rich in texture, and has different styles. It has the characteristics of pressure resistance, wear resistance, fire resistance, cold resistance, corrosion resistance, and low water absorption. 2. Artificial culture stone Artificial culture stone is made of calcium silica gel, gypsum and other materials. It imitates the appearance and texture of natural stone. It has the characteristics of light texture, rich colors, mildew, non-flammability, and easy installation. 3. Comparison of natural culture stone and artificial culture stone The most important advantage of natural culture stone is its durability, no fear of dirt, and it can be scrubbed for an unlimited number of times, but the decorative effect is limited by the original stone texture. In addition to square stones, other construction materials are difficult, especially when splicing. The advantage of man-made culture stone is that it can create colors by itself. Even if colors are not liked when they are bought back, they can be reprocessed with paints such as latex paint. In addition, artificial culture stone is mostly packed in boxes, in which different blocks have been assigned a good ratio and installation is convenient. However, artificial culture stone is afraid of being dirty and it is not easy to clean. Moreover, some culture stones are affected by the level of manufacturers and the number of molds, and the styles are limited or poor. 4. Installation of culture stone There are different ways to install culture stone. The natural culture stone can be directly applied to the wall surface. The wall surface is first roughened, then wetted with water and cemented with cement. In addition to natural stone, artificial culture stone can also be glued. First use 9 PCT or 12 PCT board to make a base, then paste directly with glass glue. 5. Precautions (1) Culture stone is not suitable for large-scale indoor use. Generally speaking, the wall surface area should not exceed one-third of the wall surface of the space in which it is located. Cultural stone wall surfaces should not appear many times in the living room. . (2) Culture stone is installed outdoors. Try not to use sandstone as it is easy to seep. Even if the surface is waterproofed, it is easy to rain and cause weathering of the waterproof layer. (3) The interior installation of cultural stone can use near-color or complementary colors, but it is not suitable to use strong and cool contrasting colors. In fact, cultural stones, like other decorative materials, must be applied according to their needs, and they should not be used to pursue the trend one-sidedly, nor should they be turned against the tide.
Hydropower and refrigeration and heating systems

(I) Water Supply Pipes The types of water supply and drainage pipes have been described in the previous section. The precautions for installation and use of pipes are described here. In the pipeline decoration, waterproofing is often more important than any topic. What issues need to pay attention to during installation and use of the pipeline?
(1) The installation of pipes must find a professional mechanic. No matter how luxurious and upscale your decoration, if you are not willing to spend money in this area, it is not worthwhile. Bursts or leaks in pipes often result in losses of tens, hundreds, or even thousands of times the price of the pipes themselves. (2) The boost test must be performed after installation. The pressurization test is generally performed at 1.5 times the water pressure, and there should be no water leakage during the test. (3) Test methods and procedures without pressurization: a. Close the main valve of the water pipe (ie the water pipe switch in front of the water meter). b. Open the faucet in the room for 20 minutes to ensure that no water is dripped and then close all taps. c. Turn off the water inlet switch of the water storage device such as the toilet tank and the washing machine. d. Open the water main valve. e. Open the main valve 20 minutes to see if the water meter is moving, including slow moving. If there is movement, it will be leaking; if it does not move, it will be fine. (4) In everyday use, if the following conditions are found, check the relevant piping as soon as possible: a. Moldy foam on the surface of the wall paint. b. Baseboard or wood floor black and fine bubbles on the surface. (b) Power lines Power lines are mainly used for artificial lighting and electrical appliances. They have to be re-layed during the recent renovation. The general standard is: (1) The main line uses 2.5mm square copper wire. (2) The air conditioning line should be 4mm squared, and each air conditioner should be routed separately. (3) Signal lines such as telephone lines and television lines cannot be paralleled with the wires. (4) Use protective plastic boxes for the wires, and use hoses (including PVC tubes) for the buried walls. The connectors must be straight or elbows. Where hoses cannot be used, metal hoses must be used for protection. (5) Buying wires, switches, etc. must buy good goods. The only mark is whether they meet the national standards. At the time of purchase, the dealer should indicate this. (III) Refrigeration and Heating 1. Refrigeration The main equipment for cooling at present is the air conditioner. Here we will talk about the relevant precautions. 1) The purchase of air conditioners. Try to use brand-name goods, as far as possible to buy a good reputation shopping malls, it is best to buy direct manufacturers to buy. Remember the warranty card and invoice. 2) The number of horses should be appropriate. The number of horses is related to the intensity of cooling. The number of air-conditioned horses in the living room has to be larger, so as to leave room for space. There is 0.8-1 bedroom in the bedroom and the living room is better than 1.5. 3) Simple program. 1 Demarcate the mounting position mark. 2 Make a variety of holes on the wall or floor. Holes through the wall, use cement to seal the gap. 3 Install the bracket or hanger. 4 sample position. 5 Follow the instructions for installation. 2. Different from heating and cooling, there are various methods of heating, including heating of air conditioners, heating of pipelines, and floor heating. 1) Heating of air conditioners. This type of heating is mainly used in areas where winter is not too low. The main advantage of An is that the heating rate is fast and it can also be used for both hot and cold. Similar devices include heaters, radiant heaters, etc. This type of heating is aimed at a specific home and it is generally difficult to take into account the heating of the entire home. 2) Pipe heating. Pipeline heating is achieved by the municipal heating plant through the coal-fired boiler and then through a centralized pipeline to the indoor heat sink for heating purposes. Due to the serious pollution of coal burning, the cleaner method is to use natural gas, but this relatively increases the cost. This kind of heating also has an undesirable consequence. The vertical and horizontal pipe sections will affect the interior appearance, and at the same time reduce the actual indoor use area by about 3%. 3) Household wall-mounted heating stove. This method is to create a heating stove for each household and heat it by means of a wall-mounted radiator. Its main fuel is natural gas or liquefied petroleum gas. 4) Floor heating. This approach is similar to heating stoves, except that it transports thermal energy through pipes laid under the floor instead of through radiators. Compared with other heating, it also has the requirements of penetrating the floor decoration materials. Some decorative materials with good insulation properties are not suitable for such indoor flooring. 5) Electric heating. Electric heating is more environmentally friendly and detachable. Its biggest drawback is that it is very demanding and its use cost is quite high. Beijing and other big cities are experimenting with this type of heating.
Under certain circumstances, the right to decide on the heating method is in the hands of the developer of the house, but we can believe that environmental protection, energy saving, and low-cost heating will continue to emerge.
Woodworking process

In the renovation project, woodworking projects often belong to a major item. From the renovation point of view, basically carpentry represents the decoration. Many owners will regard the level of carpentry as the basic level of a decoration company. Therefore, most of the decoration companies will not regard carpentry as the top priority. After a brutal market battle, latex paint fell from more than 40 yuan on the first square meter to more than 20 yuan, and the price of mud from 40 yuan per square meter fell to the point where some people even got a slushy gift. In the end, it was carpentry that made the company profitable. Because of this, carpenter quotes have been in a relatively stable state. Carpenter's quotation is not comparable to other renovation projects due to factors such as materials and design. Let's take a simple wardrobe as an example: Solution 1: Use a MDF structure with veneer inside and veneer outside. Solution II: Use big core board structure, internal brush varnish, external brush mixing oil. Solution 3: Use a large core board structure with a beryl board inside and an exterior veneer panel with varnish. Option 4: All solid wood structure, plus varnish or mixed oil (this item varies greatly depending on the type of solid wood). The above four methods are theoretically feasible, but the cost may be more than double, coupled with the design differences, the comparability is even lower. Here we focus on the process, not the material. The reason for making the above comparison is mainly to explain the difference between the process and the advanced collective. For details on wood-based panels, please refer to the relevant contents in the first section of this chapter. (A) of the main sheet metal process 1. MDF technology MDF can be divided into high-density board, MDF and low-density board. Most commonly used is the MDF. This process is most welcomed by furniture factories and professional companies (such as kitchen companies). This process depends on the suppression of the machine, and the possibility of on-site construction is almost zero. Therefore, decoration companies are rarely used. The MDF process relies mainly on component assembly. On the other hand, its finish is mainly applied instead of nailing. This paste is different from on-site production, it is mainly used to suppress the machine. Combinations of adhesive materials such as density boards and fire panels often produce very good results. The most important drawback of the MDF process is the large expansibility. After water, it is almost hopeless. Another disadvantage is the poor bending resistance, which cannot be used for high-stress projects. 2. Daxin board technology Daxin board is a relatively popular material at present, especially the decoration company. The core material of the large core board has a certain strength, and when the size is relatively small, the effect of using the large core board is better than that of other artificial boards. Of course, the construction technology of Daxinban is basically the same as that of modern carpentry. The construction is convenient, the speed is fast, and the cost is relatively low. Therefore, it is increasingly favored by decoration companies. The process of the large core board mainly uses nails. At the same time, it is also suitable for simple viscous pressure processes. The main drawback of Daxinban is its poor vertical bending resistance. When it is used as a bookcase and other projects, its large distance strength often cannot meet the requirements of the book's weight; the solution can only be the narrowing of the bookshelf. 3. Fine core board technology The core board is earlier than the big core board and is a more traditional material in modern woodworking. The fine core board has high strength and good bending resistance. In many renovation projects, it can be competent for the relevant role. In some structural parts that require load-bearing, the use of a fine core board will be more powerful. The 9mm board in the fine core board is more necessary for many projects. As with the large core board, the fine core board mainly adopts a nailing process and can also be simply bonded and pressed. The main drawback of the fine-core arc is that its own stability is worse than that of other sheets. This is caused by the difference in the material properties of the core material, which makes the deformation of the fine core plate possible to increase. Therefore, the fine core board is not suitable for single-sided parts such as cabinet doors. 4. The solid wood board process is a traditional practice. Due to the large number of types of wood, the effect is very different, but it is similar in terms of process. Solid wood panels have the advantages of good bending resistance, high strength, durability, and good decorative effect. Solid wood practices use traditional techniques and rarely use nails or glues. The skill requirements of carpentry workers are high, and carpenters who have not been formally trained are hard to do the job. In the production process, solid wood plates should be processed through cooking, insecticide and drying. The use of untreated wood has the potential to cause pests (mainly termites).
Woodworking Process Precautions

1. Treatment of nail holes The handling of nail holes is strictly speaking a category of painters. As the saying goes: “Three points of color and seven points of dress.” This expression is also typical in woodworking. Most of the renovations now use reworked plates. Shots are used during construction. How to deal with these nails has become a prominent issue. This requires a very rigorous attitude toward the color matching of the putty, as far as possible so that the color matching color is basically the same with the surface of the wood, thereby disguising these shortcomings. The same processing also applies to the processing of tree sections and tree shrews. 2. Selection of Plates The selection of excellent quality plates is the first factor in ensuring quality. Strict selection is required for the quality and suitability of the plates. First of all, we must make the right choice for the relevant part of the plate. For example, a fine core board may be used for the load-bearing material such as a bookshelf. Secondly, the quality of the relevant plates also needs to be controlled. For example, the quality of fine core plates varies widely. 3. Selection of Finishing Processes Different boards require different finishes. For example, wood veneers and veneers with beautiful textures can use varnish, and poorly-textured solid wood panels or plain plates without veneers require the use of mixed oils. Similarly, it is inferred that if varnish is used, then you should choose a solid wood panel or veneer with a better surface; if you use a mixture of oils, you only need to use a common plate. The use of veneer mixing with oil is a waste of money.
Door leaf

The door leaf is an essential item in all decoration projects. The special position of the door leaf makes it a symbol of decoration style. 1. Wind characteristics of the door leaf The style characteristics of the door leaf are mainly reflected in three aspects:
1) Design material characteristics. Door leaves are often required to be decorated with the same materials used in large quantities in the room. Therefore, we often see that in the practice of clear oil, if the interior is red, then the door is often red. If it is cherry, then the door is cherry. In the practice of mixing oil, the door leaf was mixed with oil and the color was consistent. Of course, the door leaf can also be designed in different styles, but it is very difficult to do this. 2) Design element features. The design of the door leaf tends to follow the design elements in the design style. For example, when a specific linear or curved design exists in the design, the door leaf is often required to have such characteristics. 3) style guide features. The door leaf will be designed following the overall design style, so to a certain extent, the door leaf will become the guiding target of the style. This is because there can be no other decoration items at home, but it cannot be without a door leaf. Therefore, the door leaf not only changes with the style, but also sometimes plays a leading role. 2. Type of door leaf 1) From the material. (1) Solid door. The solid door is mainly made up of the integral material or the complete material of small pieces. The width of the door leaf is generally 1900mm x 850mm. Since it is difficult to find such a large flash material, the current solid door is mainly composed of pieces. Solid doors have better sound insulation, but have less resistance to deformation. (2) Hollow door. Hollow doors are mainly made of plywood, supplemented by intermediate wood or plywood trims as the keel. Hollow doors have poor sound insulation, but they have strong resistance to deformation. Solving the problem of sound insulation performance can be solved by thickening the thickness of the two sides of the splint. Nowadays, urban doors often use fire doors, which are a kind of hollow doors, but fireproof cotton, fireproof foam and other materials are used in the splints. (3) Profile doors. Profile doors are mainly made of special materials such as aluminum alloy, stainless steel, PVC, and steel. These materials are often waterproof, etc., and are widely used in factories and bathrooms. Their disadvantage is poor aesthetic appearance, and sometimes conflicts with design styles. (4) Molded door. Molded doors are made by pressing hot presses of industrial materials. It is basically a hollow door. (5) Glass doors. The glass door is a kind of special kind of door leaf. First of all, its thickness is not enough to be a solid door, and it is not a special-shaped door. In fact, it is a special form of door leaf. The characteristics of glass doors are determined by the characteristics of the glass itself. For example, when transparent tempered glass is used, the door leaf has a transparent function, and when the frosted glass is used, it has a semi-transparent function. (6) Grid doors. Grid doors are made by round or square tube metal welding. The security door we usually see is the most important embodiment of this approach. 1) From the type points. (1) Swing the door. This is our most common left- or right-open door leaf, which is hinged on the hinge and opened manually or electrically. It is widely used in gates, bedrooms and other spaces. The swing door is a door leaf that opens in the Z-axis direction. (2) Sliding doors. Sliding doors are also a common type of door in homes. However, it will not be used in the same decoration project at the same time. Sliding doors are doors that are open in the X-axis direction. (3) folding door. Folding doors work the same as swing doors. The biggest difference is that its doors are foldable. Generally, the folding door occupies about one-third of the normal swing door. However, there are many gaps in folding doors and it is not suitable for places where strict privacy is required. (4) Freedom Gate. The free door is a special form of the swing door, which can be opened in both directions (inside and outside) of the Z axis, and can be automatically returned to the closed state after opening. Free door movement is accomplished through free door springs. (5) Others. There are shutter doors, spring doors, revolving doors, flip doors, gate doors, etc., which can be selected as needed. 3. Common Door Problems 1) Production of splint doors. The plywood door is mainly constructed on the structure. General oil practice is: first cut into 15mm plywood strips, and then put together into a grid as a keel, and then nailed on both sides of the 5mm board, and then affixed to the top layer of 3mm decorative panels. The perimeter of the door can be closed with a 1mm×5mm sealing line (also called the door side wood line). The 5mm and 3mm panels of the door leaf need to be glued and pressed with heavy objects. The glue used is preferably oily glue, such as all-purpose glue. 2) Production of stainless steel security doors. The production of stainless steel security doors is resistant to defects. An excellent method for resistance is to use a 1.0-1.2mm thick stainless steel plate as a frame, and then use 0.8-1.0mm stainless square steel to be welded at a 45-degree angle. The new practice now includes the addition of a piece of glass, both internally and externally, to solve the problem of grid cleaning inconvenience. 3) Toilet door leaf waterproof problem. To solve this problem, one is to use waterproof profiles, such as PVC or plastic steel; the other is the use of water-repellent wood or plywood. The disadvantage of the former is the lack of aesthetics; the disadvantages of the latter are complex processes and high costs. 4) Notes on solid doors. Solid door problems focus on two aspects: First, distortion, this problem is mainly offset by the reinforcement of mutual forces; second, cracking, to solve this problem can only be selected through the use of wood with better crack resistance.
window

The window is the main decorative item after the door leaf. The window is generally the content of the building's body. Here we mainly solve the problem of window covers. 1. Window Cover 1) The role of the window cover. Many friends will ask what is the use of window covers? The role of window covers is mainly threefold:
(1) The main function of the window cover is to protect the edge of the window. Because long-term use is easy to make the window edge appear damaged, and the window cover made of wood, can play a good anti-collision protection. (2) The design of the window cover has, to a certain extent, the effect of echoing with the door cover and the baseboard, because they share the role of closing edge for the entire space. (3) Window covers are the form of windowsill. When we spread a piece of marble or the like on the window sill, we often feel monotonous and abrupt; when we add the window cover, the feeling will be more complete. 2) Style features of window covers. The window cover and the door cover are echoes. Generally, if the door does not have a door cover, then the window does not need a window cover. On the other hand, if there are door covers and no window covers, there is a sense of not being completed. In most cases, the style of the window cover is required to be consistent with the door sleeve. 2. Style of window cover 1) Semicircle style. This style may be the most common, but it will gradually be eliminated. Its approach is: first use the flat bottom, then paste the decorative panel, and then use two semi-circular lines to close the edge. 2) Single line style. This style is currently used most commonly. First use the plywood to cover the bottom, then use the panel on the side and use the decorative lines to lock the edges. These lines are made by the factory into a uniform decorative pattern or shape, and construction is very convenient. 3) Double line style. This style is a kind of balance of future practice. It is the same as the single line method except that the seam is stitched using two lines. This approach can make up for the monotony of monotony caused by the monotony, the diversity of styles. However, this practice is generally only applicable to clean oil practices; the use of mixed oil, in the crack prevention construction difficult. 3. The style of the windowsill The style of the window sill is mainly categorized from the material. Common materials include marble, granite, artificial stone, decorative panels and decorative wood lines. Here to talk about the pros and cons of these materials. 1) Marble. If the selected color texture is ideal, then marble should be the first choice for window sill. The marble has the advantages of beautiful colors, various textures, and countertops that can prevent splashes of rain. 2) Granite. Granite texture is basically dominated by granules, and there are a variety of colors. Its color and texture are inferior to marble, but it is harder and more durable than marble. 3) Artificial stone. The texture of artificial stone does not have many features, but the color has more options than the natural stone mentioned above. There are, but not many, artificial stones to be used on the windowsill. 4) Decorative panels. Decorative panels are used as windowsills. One show follows the practice of window coverings, except that the surface layer is no longer paved with other materials but directly uses decorative panels. This approach is generally applicable to narrow ledges, and the bay windows are less suitable. 5) Decorative wood line. The effect of decorating the wood line is somewhat similar to the park's long bench. This design is generally suitable for bay windows, and it is not too cold in winter and not too hot in summer. The main thing is that it is more innovative and new. 4. Window opening type According to the opening method, windows can be divided into the following two types: 1) Casement windows. Casement windows are generally open outwards and are also divided into single and double fans. 2) Sliding window. The windows are opened along the track to the left and right, and generally two windows are required to form a sliding window.
Paint process

Paint is also a very common item in the decoration. There are even "three points of carpentry seven points paint" in the industry. The commonly used paint process steps are described below for your reference. (a) Wood lacquer 1. Varnish
(1) Coloring oil or coloring oil (Note: Only for projects that require color change, ordinary processes do not require this process). (2) Brush the varnish protection primer (if there is no 1 process, this is the first process). If the original color is used for varnishing, then the surface must be cleaned after the material is purchased in the site and the primer should be immediately brushed for the first time. Primers are also generally topcoats. Note: The varnish finish must be applied before wall painting. (3) Clean up dust and dirt on the wood surface. (4) Use sandpaper to polish the surface of the board or wood. (5) brush the first time paint. (6) After drying out, use the formulated toner, cooked rubber powder, and fly-fly powder to adjust the putty to disguise the eyes, such as nails and tree shrews, so as to match the color. (7) After the drying process, the rough part of the toner is polished with fine sandpaper. This time is critical. (8) Brush paint again. (9) Dry thoroughly with fine sandpaper. (10) Brush paint again. That is, once the paint is applied, sandpaper is used to polish it, and so on. If there is a special primer, change the first pass to a special primer. (11) Wipe the surface of the woodware with a wet cloth, and then wet the surface with sandpaper, and then polish the surface, commonly known as watermill. (12) Brush the last time the paint. In general, counting the last lacquer, a total of 4-8 strokes will be required to achieve a superior quality. The more surface paints the better, but generally not more than 10 times. In the wet weather construction, the film will have a whitening phenomenon. Adding 10%-15% of the diluent to the nitromagnetized white water can be eliminated. 2. Contamination process (1) Clean up the dust and dirt on the surface of the wood. (2) Use pig blood and fly powder to mix well with the surface of the wood. (3) Dry with sandpaper. (4) brush the first time paint. (5) Make up for bad points. (6) Dry with sandpaper. (7) Brush the paint a second time. (8) Dry with sandpaper. (9) Brush the paint three times. In general, it is advisable to mix oil 2-3 times. (B) wall paint 1. Hand brushing paint process If the wall is an old wall, you need to wipe the surface after the wet water. After drying, paint over the varnish. If it is an old house and the matrix is ​​good, it can be sanded once or twice using coarse sandpaper and it does not need to be scraped. (1) Flatten the entire wall with 108 glue, cooked rubber powder and fly powder after mixing into a putty. (2) After polishing, polish with light sandpaper. The above steps are generally repeated three times until the wall is flat. (3) Brush topcoat (latex paint) again. (4) Dry thoroughly with fine sandpaper. (5) brush the second time finish. 2. Painting process If the wall is an old wall, wet surface water must be scraped first. After drying, paint over the varnish. If it is an old house and the matrix is ​​good, it can be sanded once or twice using coarse sandpaper and it does not need to be scraped. (1) Flatten the entire wall with 108 glue, cooked rubber powder and fly powder after mixing into a putty. (2) After polishing, polish with sandpaper. The above steps are generally repeated three times until the wall is flat. (3) First pass finish (latex paint). (4) Dry thoroughly with fine sandpaper. (5) spray the second time finish. (3) Precautions (1) The paint must be applied within the room temperature required by the product. Different products have different temperature requirements. This can be found in the product packaging or in the manual. (2) Each process ensures that the dry side performs the second pass. (3) Use the same kind of paint, do not mix different types of paint to avoid adverse reactions. (4) During construction, safety measures should be taken, such as wearing masks. (5) Maintain indoor ventilation to prevent poisoning. (6) Use gel gloves when using certain corrosive materials such as Tina Water. (7) Do not smoke or use open fire at the construction site to prevent fire or explosion. (8) Avoid forced construction under high humidity or cold conditions. (9) There is a gap in the ceiling or wood partitions that needs to be masked. It can be treated with putty, and then it can be attached with high-quality anti-crack tape. The cracks in the wall can be scraped and filled into the plaster to be processed, and then the high-quality protection can be applied. Cracked tape. Then paint the finish. (10) Adhere to shopping malls or experts to buy paint to prevent counterfeiting, although the price will be slightly higher, but at least the quality will be guaranteed.
Mobile furniture
(A) leather seats, sofas 1. Leather chairs, sofas based on their selection of different materials, the general common yellow leather, buffalo leather, pigskin, sheepskin and other several. At present, there are fake products on the market. How do we distinguish leather and fake leather?
(1) Look at the surface of the leather for pores. The skin pores of leather are fine and dense, irregularly arranged, and the cortex is smooth and clean; the pores of pigskin are in a product-shaped triangular arrangement and the cortex is loose. (2) Press with your fingers during examination. (3) Examine the cortical marginal section. As counterfeiting technology is getting better and better now, it is getting harder and harder to analyze from the front, and you can see some differences from the cross section of the cortex. The cortex of the dermis is loose, while the false skin is denser. (4) The dermis and false skin can also be distinguished by odor. The dermis has an odor of the animal, and the fake skin is relatively more irritating to the odor. In addition to the full leather sofa, there are some semi-leather sofas with fake leather on the back side, these are all consumers need to pay attention. 2. Maintenance of leather sofas (1) Do not use leather chemicals to clean the leather surface. Use diluted soap water or special leather cleaners as much as possible. These can be purchased in large supermarkets. (2) Use a soft cloth when rubbing, and use less force. (3) Do not place hard objects on the sofa during normal use, especially to prevent children from jumping on them. (4) Do not place it in direct sunlight for a long time so as not to damage the cortex. (5) Regularly apply aqueous wax to protect the cortex. (2) Cloth Sofa Cloth sofa is very popular on the market, especially in some urban families. 1. Three advantages of fabric sofa 1) Good look and feel. Fabric sofas can use different fabrics to make coats, with rich colors and patterns and large choices. 2) feel good. The fabric sofa feels soft and warm, and different fabrics have different touches. 3) Can be replaced. When the coat fades in time, you can buy a new cloth instead. Coat replacement can be used as a refurbishment of the sofa. You can also choose your own favorite fabric, according to different seasons throughout the year, choose a different color coat, full of personality. 2. How to maintain the fabric sofa (1) When purchasing, use a cushion that can be turned over. In use, flip regularly. (2) Fabric sofas can be sprayed once with fabric protection agent after purchase for protection. (3) Vacuuming regularly. Use special fabric cleaners when cleaning. (3) Solid Wood Furniture Solid wood furniture includes what we generally call mahogany furniture and some other European-style solid wood tables and chairs that are currently on the market. Redwood tables and chairs generally have corresponding unloading controls. Nowadays, the tables and chairs on the market are mostly Ming, Qing and Republican styles, and there are also great differences in style. The general lines of the Ming Dynasty were relatively simple and had a sense of power. In the Qing Dynasty, they were more sculpted and more complex in shape. Among them, animals, flowers, and auspicious totems were mostly present. The tables and chairs of the period of the Republic of China were relatively moderate and the shapes were between the two and biased towards the latter. Most wooden tables and chairs on the market are made of mahogany or rosewood, but from the actual situation, there are also many kinds of low-grade wood plus color palettes. At the time of purchase, asking for tickets and specifying the materials used by the tables and chairs is the most critical. The use of traditional solid wood furniture in decoration is generally based on the elderly. One is the use of traditional solid wood furniture in traditional decoration, and the other is the use of traditional furniture in modern decoration, reflecting a kind of treasured taste in daily use. European solid wood furniture is one of the newer styles that have emerged in recent years. It is generally lighter in color and simpler in shape, and is supplemented by soft pillows.由于其价格便宜,因此被非常多的年轻人尤其是新婚夫妇选用。实木家私的保养比较简单,一般使用普通清洁剂甚至清水即可。唯一要注意的是防白蚁,这种问题一般发生在南方。如果在晚上听到轻轻的锯木声或者家私下有木质粉末,那么就很有可能受到白蚁侵害了。对付白蚁的办法是使用CCA(铜铬砷合剂),但最好是请专业白蚁防治所来操办,以免造成更大的危害。选购哪一类型的移动家私,要视自己的生活习惯和家庭装修的风格进行,不然很容易出现不伦不类的效果,花钱不讨好。
灯具照明在装修中,灯具是必不可缺的,与其说是装修的项目,倒不如说是最基本的生活需求。 (一)人工照明的基本概念谈到人工照明,首先要先了解一下照明的基本概念: 光通量:人的眼睛所能感觉到的辐射能量,每一波段的辐射能量与该波段相对视见北之乘积的总和,单位为1mm(流明)。 照度:指照射到一个表面的光通量密度,单位为1x(勒克斯)。11x=11m/平方米。一盏40w的白炽灯的光通量约为340lm;一盏40w荧光灯的光通量约为1700-1900lm。 家居照明的灯具设置有两种办法: (1)按一般照明与特殊情况设置两组方案,例如书房用一盏小灯和一盏亮度较大的台灯。 (2)按特殊情况设置一组方案:例如书房只设置一盏大灯。 上述第一种方案是较佳的选择。首先根据不同的情况,选择不同的照度,有利于保护视力,避免长期过强或过弱的光线对视力造成伤害;其次,有利于节约用电,从而节省开支。 (二)灯具的选择1.灯具的款式(1)首先要根据室内设计的风格业购买灯具。例如现代风格,就适宜选用一些不透钢和磨砂玻璃组合的灯具;而欧美的传统风格,就适宜选用一些诸如洛可可线条、涂有金属色粉的灯具。 (2)在可能的情况下,客厅、餐厅和卧室的灯具可选用同一种设计款式的。按照笔者的经验,这是可能的。另一种方案是,客厅和餐厅保持同一种款式,而卧室的灯具则使用另一种款式。 首先要解决客厅灯的款式,如果客厅是大号的,那么卧室用中号的,而餐厅就用不号的,或者卧室和餐厅相反。 (3)卫生间和厨房的灯可以用防水吸顶灯,颜色与天花板尽量一致;阳台灯买白色带罩的就行了。一般不需要太关注于风格,其最主要的是实用。 2.灯泡的类型目前家用灯泡主要他为白炽灯、节能灯和日光灯等。白炽灯是利用钨或其他金属丝导电发热原理发光的,光线呈黄色(太阳色);节能灯是利用气体放电的原理发光,它学名叫自镇流荧光灯,光线除白色(冷光)的外,现在还有黄色(暖光)的。 一般来说,在同一瓦数之下,一盏节能灯比白炽灯节能约80%平均寿命延长8倍,热辐射仅20%。非严格的情况下,一盏5w的节能灯约相当于25w的白炽灯的光照,7w的节能灯约相当于40w的白炽灯的光照,9w的节能灯约相当于60w的白炽灯的光照。但目前市场上一些产品价格偏高,质量又不怎么样,如果选择不当,往往出现“节能不节线”的问题。 另一个需要注意的是,一般的节能都是不能调光的,所以只能用普通的开关。切莫使用时钟式的调光开关对节能灯实施控制。但据报道,国外已经研出可以调光的节能灯,但笔者在写稿时尚没有在市场上发现。 日光灯主要作为普通装修的室内照明和高级装修的漫射灯源。 (三)购买灯具的十个步骤灯具的选购也是非常花精力的。在去购买之前,要充分做好“颈部预热动作”,转一转头部,要不然您买完灯回来一定会为颈子酸而叫苦连天。 现列出购买灯具的十个步骤: (1)找一个卖灯比较集中的地方去买。最好选择灯具专业市场,因为款式集中,您可省时、省事、省力,而且价格也有可比性。 (2)先大体看一下,不要细看,如果看上去没有合适的马上走人。 (3)大体看上去有合适的话,进去后,第一件事找张有背的椅子坐下来,不忙着看,先喝杯水;别傻乎乎地站在那里面和店主或者服务人员议论。 (4)看灯时,把身体顺着椅背靠后往前看就行了,尽量不看超过60度的位置。 (5)看到有合适的灯时,让店打开来看看,除非您已经很喜欢了,否则先不要走到灯下面转来转去。 (6)看上一款灯后,再检视还有没有其他房间灯具,先坐着把这些东西搞定再说。 (7)看上去都有了,再站起来去细心地选。 (8)千万不要逢灯都问价格,没意义。除非您已经看上了,让对方把您所要的通通报一个书面的价格。 (9)仔细地研究这份书面报价,不合适的话,就跟店主说,回去研究一下。然后去找另一家。 (10)如果觉得款式和价格都合适,才跟对方说:我想买这些灯,您给我报一个实在的体格。如果您认为价格还是不合适,就换一家。 (四)特殊灯具的安装家用灯具特殊安装的地方主要是造型天花部分,很我人都喜欢暗装漫射灯,但不一定大家都能装好。技巧是: (1)着尾相接。荧光灯要一根接一根地装。由于不是经常用漫射灯,因此别心痛。 (2)灯管的最高位置与造型天花的灯槽框边同一水平。 (3)有弧形的地方可用小光管(荧光灯),别一根大的了事。 (4)灯的颜色可用白色、黄色和蓝色(紫色)的,别的颜色千万别用,尤其是红色和绿色。前者简直像歌舞厅,后者变成了恐怖地带。
窗帘的选择窗帘在室内装修中,起着保护隐私、利用光线、装饰墙面、吸音隔噪的作用。依据其作用的轻重,窗帘的选择又有很多不同的的组合方案。总之,窗帘的选择是一个相当关键的项目。无论是业主,还是室内设计师,都应予以高度重视。 (一)从功能上了解窗帘
1.保护隐私对于一个家庭来说,谁都不喜欢自己的一举一动在别人的视野之内。从这点来说,不同的室内区域,对于隐私的关注程度又有不同的标准。客厅这类家庭成员公共活动区域,对于隐私的要求就较低,大部分家庭的客厅白天都是把窗帘拉开,因此多处于装饰状态。而对于卧室、卫生间等区域,人们不但要求外面看不到,而且要求连影子都看不到。这就出现了不同区域选择不同窗帘的问题。客厅我们可能会选择偏透明的布料,而卧室则选用较厚质的布料。 2.利用光线其实保护隐私,还是通过阻拦光线来发挥作用。这里所说的利用光线,是指在保护隐私的情况下,有效地利用光线。例如一二层的居室,大家都不喜欢让外面走来走去的人看到室内的一举一动,但长期拉着厚厚的窗帘又影响自然采光,所以类似于纱帘一类的轻薄帘布就应运而生了。 3.装饰墙面窗帘对于很多普通家庭来说,是墙面最大装饰物。尤其是对于一些“四白落地”的简单装修的家庭来说,除了几幅画框,可能墙面上的东西就剩下窗帘了。所以,窗帘的色泽、款式等,往往起着举足轻重的作用。同样,对于精装的家庭来说,合适的窗帘将使得家居更漂亮、更有个性。 4.吸音降噪我们知道,从声音的传播方式来说,高音是直线传播的,而窗户玻璃对于高音的反射率也是很强的。所以,适当厚度的窗帘,可以改善室内的声音效果;同样,厚窗帘也有利于吸收部分来自外面的噪音,改善室内的声音环境。 (二)根据要求选购窗帘1.设计风格我们知道窗帘有很多种类型的款式,而这些款式又与室内设计风格有着密切的关系。所以,在窗帘的选择方面,设计风格是第一要求。也就是说,窗帘的一切因素,首先要与室内的风格相配套。在这一点上,您需要更多地咨询您的室内设计师,以免出现不协调的现象。 2.功能需要根据不同的功能要求,在设计风格一致的基础上,需要对窗帘的厚薄作出选择。一般来说,对于卧室有两种方法: (1)采用一种较厚的布料。 (2)用一种较厚的布料,同时里面做一层薄纱帘。 至于采用何种方案,这需要考虑实际的情况,例如有些设计风格就不允许用薄纱帘。 3.选择布料窗帘的布料有很多种选择,下面简单介绍一下有关布料: (1)轻、薄透明或半透明的布料,如棉、聚酯棉混纺布、玻璃纱、精细网织品、蕾丝和巴里纱等。 (2)中等厚度的不透光布料,如花式组织棉布、尼龙及其混纺布、稀松网眼布;滑面布料,如擦光印花棉布、磨光棉布、仿古缎子、真丝和波纹绸等。 (三)根据设计风格选择花色即使一种布料,花色也五花八门。选择不同的花色,对于设计的形式有着很大的影响。 (1)窗帘的主色调应与室内主色调相适应。补色或者近色都是允许的,得是极端的冷暖对比却是一个大忌。 (2)现代设计风格,可选择素色窗帘;优雅的设计风格,可选择浅纹的窗帘;田园设计风格,可选择小纹的窗帘;而豪华的设计风格,则可以选用素色或者大花的窗帘。 (3)选择条纹的窗帘,其走向应与室内风格的走向相配合。
家庭小饰品这里里所指的小饰物包括扮美家居的画框、花瓶、雕塑体等可移动的饰物。家居装修完毕后,它是不可缺少的项目。 (一)画框和照片框家居中出现的画框和照片框有很多类型,规格也很多。
1.画框画框可以用于主装饰墙面的装饰,大概可以分为三类:国画框、油车框和装饰画框。 1)国画框。一般框条较细。主是装裱各种国画。 2)油画框。一般框条较大,而且多数带雕花饰边,用于各种西洋画的装裱。 3)装饰画框。形式多样,一般以细框条为主。 2.照片框照片框主要用于台置或墙挂之用。照片框常见的装饰位置包括沙发转角、墙面、床头等。 3.使用画框装饰的注意事项1)框条的颜色要尽量与整体色调相适应。如果是较为现代的风格,可以选择黑色、白色和彩色的框条;如果是中式的,只能使用黑色和原木色的框条;古典欧式的风格应尽量选用金黄色的框条。 2)画面的内容要与风格相符。现代风格,尽可能选用装饰画;中式风格,则可以选用各种风格的国画装饰;古典欧式风格,较为妥当的装饰画面则是油画。 3)画面的大小要与墙面大小协调。下面的大小可供参考(假设墙面宽为3m): 一幅画:画面最大宽度以1-1.5m为宜,其中主装饰墙可增至2m。 二幅画:画面最大宽度以0.5-1m为宜,摆设时可以平行布置。 三幅画:画面最大宽度以0.3-0.5为宜,摆设时可以用高低中或者平行布置。 四幅画:画面最大宽度以0.3-0.5m为宜,摆设时可以用平行布置或者四方形格局布置。 五幅画或以上:画面最大宽度不再受限制,但一般以小幅画为主,以排列有序为准。 (二)雕塑家居中出现的雕塑以圆雕为主,其中又以树雕和石雕居多。现在市面上也有较为便宜的石膏塑和复合材料雕塑,包括各种动物、人物的雕塑。在家居布置雕塑的要点是: 1)石雕。适用于现代风格或者较为明亮的风格之中。 2)树雕。适用于多数的风格之中,古典欧式风格除外。 3)石膏雕塑。一般不建议采用,因为不好清洁,而且近地处容易碰损。 4)金属雕塑。要视具体的材质配合相适应的环境。 总的来说,雕塑是较为容易装饰的一种饰品,但具有明显风格特征的雕塑不宜在某些风格的装修中使用,例如大卫像等不能在中式风格中使用。 (三)陶瓷及水晶饰品各种陶瓷(例如花瓶)及水晶饰品越来越受到业主的喜欢。陶瓷制品主要包括黑陶、灰陶、景德镇青花瓷、紫砂拉坯等制作的花瓶等饰品,水晶饰品的主要分为水晶及仿水晶(玻璃)饰品。 一般来说,这类饰品对家居有点缀作用,但对家居的风格影响不大,所以多数情况下,此类饰品可以在多数的风格中使用。值得留意的是,在餐台之上,摆设整齐的杯碟很多时候也可以成为家居饰品的漂亮一角。 (四)花现在市场面上的人造花层出不穷,有一些花的造型甚至逼真到近在眼前都不一定能分辨出真假。如果您没有精力整天去服侍那些有生命的花花草草,同时又有点爱美之心的话,那么人造花就是值得您考虑的一样东西了。至于花的种类,要求不是很高,只要自己喜欢就行。 花草的装饰,最主要的注意点是不要泛滥,太多的花草会喧宾夺主。 (五)模型模型在家居装饰中具有一定的分量,它包括各种各样的飞机、车辆、航艇、士兵、建筑物的模型。很多人,尤其是30左右的年轻人,特别喜欢这种饰物。 模型饰品一般较多用于私人空间,例如儿童房和卧室。作为一些有特殊职业背景的人士,例如海军退役人士,会比较喜欢在客厅这些显眼的位置放置一艘大比例舰艇的模型来表露自己的人生经历。 (六)收藏品这里所说的收藏,也许已经包括了以上的东西,但它比一般的饰物更显示出主人的爱好。作为饰品,这类收藏品一般物件较大,其中包括军用品、民用品和一些民俗用品的收藏;诸如此类的小收藏品一般不用于饰品。例如有的人喜欢收藏茶具,那么在这方面就可以有所显示。
施工安全本节所述内容绝非儿戏,请各位务必注意。施工的安全问题主要包括防盗、防火、防水、防危、防电、防化等。 1.防盗在装修期间,尤其是室内的窗户、防盗网等没有做好之前,注意梁上君子对此蠢蠢欲动。另外,在装修时也必须防内贼。偷工具的、偷工场内材料的,特别是包工不包料的,业主或者管理方都要留意。 2.防火(1)禁止在工场内生火、吸烟,应在明显处张贴“禁止烟火”警告牌。 (2)不得在没有绝缘管道保护下乱拉电线,临时接线应尽量远离易燃装修材料。 (3)必须在工场内做饭的,一定要在指定的范围内进行,该区域应是没有火患危险的。 (4)必须绝对禁止在室内生火取暖。 3.防水(1)建议装修材料在堆放时垫高20-30cm,使其与地面脱离。 (2)小心用水,特别是在排水系统没有做好之前。对工人在工场洗澡的,要向其再三嘱咐。 (3)离开工场时,检查水龙头是否关紧。 (4)不得让不懂管道施工的工人从事排水施工。 (5)铺设实木地板或复合地板的,应注意临近区域的防水。 (6)没有人员值班时,应关紧窗户。 If you are in a period of ventilation, try to avoid the typhoon season. (7)定期清理排水孔,以免堵塞而造成淹水事故。 4.防危(1)装修材料放置妥当,尖角物品要适当预保护,防止碰撞受伤。 (2)小金属配件要放置妥当,尤其是钉子。 If nails are nailed on waste wood boards, they must be bent and pressed in time. (3)高空作业要做好安全措施,配备足够的高空作业装备。 (4)稳固天花板工程、安装灯具等,一定要打好膨胀螺丝,多打一点以防万一。 (5)应由受到正式训练的人员操作各种施工机械并采取必要的安全措施。尤其要注意电锯、高压射钉枪等机械的安全使用。 5.防电(1)电线排座不宜在地上乱拉,更不宜在其上面碾压。 (2)电线管道禁止在积水中通过,以免漏电时造成人身伤害。 (3)电线管道表层有破损的,应及时更换。 (4)电源箱要安装必要的接地线和漏电保护开关。 (5)电工项目应由受到正式训练的电工负责。 6.防化(1)小心放置各种化工材料,并采取一定的隔断措施。 (2)施工时,不应大量施工,要保护持一定的限度,以免空气中含有大量有毒物质而造成中毒、爆炸等意外。 (3)油漆调试、施工时应保持室内通风。 (4)使用化工材料时,要采取戴胶手套等保护措施。 (5)对于不明物体或者材料,切记不要乱拿乱碰。 (6)不要在没有行家指导下擅自调配化工原料。 (7)对于强酸、强碱、强挥发性材料要加强安全防护。
防盗网与电子监控不知道最早从那个地方、从什么时候开始,防盗网如雨后春笋般出现,直到到铺天盖地。先是用小铁条,后来用扁铁,再后来出现了越来越粗的不锈钢。 近年来,一此现代派人大力批判防盗网,并鼓吹使用电子监控系统。 在室内设计界,有一句非常著名的话:功能第一,形式第二。而在防盗网这个问题上

,恰恰是功能与形式的最典型冲突。笔者就此谈谈一些看法。 1.防盗网笔者认为防盗首先是一咱社会现象的反映。80年代末,国内治安开始恶化。在当时警力不足和现实情况下,防盗网是一个非常有效的自我保护方法。 1)防盗网的好处和坏处。防盗网有3个好处:①加强防盗保护;②增加室内实用面积;③防止小孩在窗口玩耍时不小心摔下。 防盗网也有3个坏处:①发生火灾时,减少逃生的机会;②有碍观瞻,影响建筑外观;③防盗网成为盗贼非常有利的攀爬物,危害没有装防盗网的居室的安全。 2)防盗网设计和使用中的注意事项。 (1)防盗网的设计,尽量采用统一的款式,保持建筑的统一外观,这是利己利人的做法。 (2)防盗网的安装一定要使用膨胀螺丝,并多点固定。 (3)不要在防盗网上放置重物。 (4)防盗网的设计,尽量使用不锈钢材质,以免锈迹斑斑,既碍观瞻又不利于使用。 (5)防盗网的设计,应预留足够大的逃生门。有人也许会说窗户底下没有楼梯要逃生门做什么?放心,消防员有云梯。 (6)逃生门的锁具应定时(半月)开启一次,以确保状态良好,并定理(每月)上润滑油。 2.电子监控电子防盗分为两种:集群电子防盗和室内电子防盗。 1)集群电子防盗。也叫小区监控,是通过小区在各个角落设置的闭路监控系统进行监视的。主要形式有两种: (1)闭路摄像机。通过闭路摄像机把有关的图像传送到小区值班室进行监控。 (2)红外线探测仪。一些非通行区域,例如围墙边设置红外线探测仪,使小区值班室能知道在该区域出现情况。 2)室内电子防盗。也叫室内监控,是通过安装在室内的探测系统进行监控的,发生情况时,会把报警信号传送至小区值班室,同时,室内也可设置遇警警号。 3)探测头的基础知识。 (1)红外探测头。它是通过探测人体辐射的特定波段的红外线实施发的。红外线可以采用直线探测,也可以实施扇形探测。 (2)微波探测头。是通过室内物体移动实施触发的。 (3)双探测头。就是同时采用红外线与微波触发。这是一种保险的做法,因为红外线容易被干扰,而且通过一定手段减少身体红外辐射量,而微波的误警率高。两者结合,有利于提高探测的准确度。 3.防盗网与电子监控的比较(1)防盗网是一种多用途的防盗形式,并且具有一定的明示阻吓作用,这种阻碍是一般盗贼所不能不估量的。 (2)电子监控是一种较为纯粹的防盗形式,除非是事先盗贼已经知道,否则可能起不了阻吓作用。相反,如果盗贼已经侵入室内,当报警系统呼叫时,可能会采用对居住人员不利的行动,而不是逃之夭夭。 (3)防盗网的价格相对便宜,而电子监控要做到防盗网那样的全层防范,价格可能会高出数倍甚至十几倍。 (4)防盗网可以承担独立的防御功能,当发现盗贼采用暴力破坏时,应有足够的时间报警求助。 (5)电子监控不能独立动作,它需要有一个较为系统的防御体系,例如完整的小区隔断措施和小区保安。 总而言之,笔者认为,即使采用电子监控,也应该在窗户、阳台等部位内部采用一定的硬措施,例如钢窗花。家居防盗不适宜采用完全的软措施。在这一点上面,笔者还是认为应“功能第一,形式第二”。
地面装修及装修材料在工程项目中,地面装修的造价占相当大的比例,所以大家都非常关注。家居地面装修的材料主要有瓷砖、实木地板、复合地板和石材(大理石及花岗石);地毯等用得相对较少。 (一)瓷砖有一部分业主除了关心瓷砖的选料外,对瓷砖铺设不大注意。其实,这里还是有些需要注意的。首先,地面要打平。有一些土建地面不平,应该把不平的地方用水泥沙浆铺平。铺设时如果地面面积较大,可以做一些拼花,也可以用不同色彩的瓷砖(较深色的)把周围框起来,而框内的瓷砖用较浅色的。当然,厨房和厕所的地面一定要有倾斜度,这样是为了方便排水。瓷砖铺设时,一定要讲究留缝。瓷砖留缝,不但是为了处理规格不整的问题,而最主要的是给热胀冷缩留位置。现在一些对所谓无缝瓷砖的炒作,消费者们需要注意。抛开装修不说,我们从物理的角度去看就知道。瓷砖多数在一个相对封闭的空间施工,以墙面为例,一般左右及下面部分是有固定墙和地面封闭的,如果瓷砖在施工中无缝处理,那么膨胀时,它往哪里伸长呢?很明显,无缝瓷砖要实现的一个前提是瓷砖的热胀冷缩率为零。我们知道,这个可能性是零。那么强行无缝处理的后果是什么?瓷砖不可能热胀冷缩推倒墙面,因为其背面黏合力不可能大于推动墙面的力量。那么后果有一样:瓷砖拱起。除非您对工人的施工工艺水平有十足的信心,否则尽量不要选用规格超过900mm×900mm的大地砖,这类大砖由于施工时中间部位容易含有大量空气,日后容易产生一系列问题。瓷砖留缝,墙面以1-2mm为好,一些小砖(100mm×100mm)为了美观,留缝反而需要大。地面留缝,除了复古砖需要留较大的缝隙(5-10mm)外,其他的砖种一般以3-10mm为好。对于家里有老人的家庭,在选用地面材料时,尽量要少选用一些太滑的抛光砖和玻化砖,否则千万意外,得不偿失。瓷砖铺好后,业主应该懂得怎样验收。验收的关键是两个字:“平、直”。首先任选一块地方(以4块600mm×600mm砖为例),将水平尺按对角线的方向放下,横跨两块对角的砖,看看是不是平的。然后测定每两块上下左右相邻的砖。如果是平的,水平尺中间的水珠应该在中间(此方法不适用于厨房和厕所)。最后就是看看边角是否对直。如果您先取的料是好的话,此办法可测定泥瓦工的水平。 (二)石材石材的铺设,绝大部分与瓷砖一致。但也需要注意的是:石材的铺设,要确保石材底面水泥沙浆的充足,施工时要轻压使空气排出。如果留下空气,会使石材日后产生松动。除了我们经常看到的大理石与花岗石外,装修中经常使用的石材还包括鹅卵石、雨花石等。鹅卵石是在平缓的河床中经过亿万年的冲刷而成的椭圆形小石头。雨花石其实也是鹅卵石的一种。习惯上,我们
