A friend of Xiaobian called to ask for help. His bathroom leaked water and made his neighbor's house "water flooded Jinshan". He went to the neighbor's house to apologize and lose money. The neighbor was still very dissatisfied, which made him feel depressed inside. In order to help a friend, Xiao Bian invited the highest level of Huang Shifu in the construction team to go to a friend's house to check the bathroom waterproofing. What happened? Master Huang went through the inspection and said that the original waterproofing had great problems in the construction of the joints. Causes serious water leakage. Xiao Bian wants to remind the owners that the waterproof of the bathroom is too big. If the waterproof quality of the bathroom is not enough, you will be beautifully decorated with clouds. Sending a small flood will make you "bubble". In this issue, we will Let me talk about the precautions for waterproofing the bathroom. If the old house is refurbished, it is necessary to change the original floor tiles of the bathroom. After the original floor tiles are cut, it is necessary to first level the ground with cement mortar, and then do waterproof treatment. If the water is not leveled, there will be unevenness and leakage. After leveling, it can prevent the waterproof coating from leaking due to uneven thickness. Before doing waterproofing, it is necessary to clean the floor and repeat it with water-repellent paint for 2 to 3 times. The brush should be light and thin, and the last time it is waterproof, it can be brushed once. The joint between the wall and the ground and the joint between the water and the upper and lower sides of the pipe are the places that are most likely to present problems. It is inevitable to urge the workers to dispose of these corners and corners, and the waterproof coating must be applied in place. Require the decoration team to make the cement roots for the upper and lower pipes of the kitchen and the bathroom. Brush the waterproof coating from 10 to 20 cm from the ground, then re-do the waterproof layer on the ground, and add the original waterproof layer to form a composite waterproof layer. Strengthen water resistance. Make wall waterproofing before wall covering tiles. In the ordinary waterproof treatment, the wall surface should be waterproofed to a height of 30 cm. However, for a non-load-bearing light-weight wall, the entire wall should be waterproof, at least 1.8 m high. If a bathtub is used, the height of the wall waterproofing paint adjacent to the bathtub is also higher than the upper edge of the bathtub. After the waterproofing project is completed, seal the door and the drain, fill the toilet floor with water to reach the height of the liquid level, and make a mark. If there is no clear drop in the liquid level within 24 hours, no seepage is found on the roof of the house downstairs. Leak, waterproof will pass. If the acceptance fails, the waterproof project must be redone and re-inspected. Regarding the acceptance of the waterproof construction of the lightweight wall, the water spray test should be accepted. Even if the water pipe is used for the waterproof coating, the surface is not continuously sprayed for 3 minutes from the top to the bottom. After 4 hours, the other side of the wall can be inspected. Whether it will present a saturated scene, if there is no immersion scene, it can pass the wall waterproof construction acceptance. During the construction process, when the pipeline, floor drain, etc. pass through the floor, the waterproof layer around the hole must be carefully constructed. The water pipe is buried in the wall to achieve a reasonable structure. The water pipe is made to make a groove larger than the pipe diameter, the plaster in the groove is smooth, and then the waterproof paint is brushed in the groove. The floor of the kitchen and the bathroom must be sloped to the ground, and the slope should be appropriately increased. When the pipes in the kitchen and bathroom are renovated, the original drainage and sewage pipes and floor drains should be prevented as much as possible to prevent leakage due to damage to the waterproof layer from the new pipe slab. .
Guide Ring is a mechanical seal, also known as a guide ring. It is usually made of metal or plastic and used to support and position pistons or rods. Guide Ring has excellent wear resistance and corrosion resistance, which can effectively reduce leakage and friction, thereby extending equipment life. Guide Ring is widely used in the hydraulic, pneumatic, mechanical, and automotive industries as an important mechanical seal.
The classification of Guide Ring can be divided by material, structure, and purpose. According to material classification, Guide Rings are mainly divided into metal Guide Rings and plastic Guide Rings. Metal Guide Rings are usually made of metals such as copper, iron, and stainless steel, which have high strength, wear resistance, and high-temperature resistance; The plastic Guide Ring is usually made of polytetrafluoroethylene (PTFE), nylon, polyimide and other materials, with good corrosion resistance and low friction coefficient.
According to structural classification, Guide Rings are mainly divided into unidirectional Guide Rings and bidirectional Guide Rings. A unidirectional guide ring can only withstand pressure in one direction and is typically used in hydraulic and pneumatic systems; The bidirectional guide ring can withstand bidirectional pressure and is typically used in the mechanical and automotive industries.
According to usage classification, Guide Rings are mainly divided into piston Guide Rings and rod Guide Rings. The piston guide ring is usually used to support and position the piston, preventing friction and leakage between the piston and the cylinder liner; The rod guide ring is used to support and position the rod, preventing friction and leakage between the rod and the seal.
