Tile wall tile quality acceptance

Tiles are used in every home renovation, so the quality of acceptance of ceramic tile materials must be judged from these aspects:

First, hand detection

Second, drip test:

The higher the density of tiles, the faster the water absorption shows that the density is sparse and the quality of the water is slower. The glazed tile (wall tile) has a high water absorption rate, but when the density of the green body is too loose, it is not only the problem of water absorption but the problem of cementation. That is, cement sewage will penetrate the surface and cause black stain on the surface of the tile.

Third, to identify the color difference:

Due to the large number of purchases of wall tiles, if there is a significant color difference between multiple packages, the decoration effect is very much affected. It is necessary to compare the samples of all packages and observe the changes in the color difference. The color difference can not be selected.

Fourth, use the ruler:

The higher the accuracy of the tile side length, the better the effect after paving. Buying high-quality tiles is not only easy to construct, but also saves man-hours and accessories. Using a tape measure to measure the size of each tile, whether there is any difference in the circumference, the product with a size error of more than 0.5 mm and a flatness of more than 0.1 mm will not only increase the difficulty of construction, but also have a poor effect after renovation and cannot be used for engineering.

V. Perform visual inspection at the site:

Observe whether the product has missing sleeves, spots, cracks, axial blebs, corrugations and other obvious quality defects. The above defects must not be used.

Listen to the sound:

With hard objects tapping, the more crisp the sound, the higher the porcelainity and the better the quality. You can also use your left thumb, forefinger, and middle finger to clip a corner of the tile. Hang it down easily and tap the lower part of the tile with your right index finger. If the voice is clear and sweet, it is the top grade. If the sound is boring, the turbidity is the next product.

VII. Ask for a report:

Finally, the other room asked the dealer for product quality inspection certificate and quality inspection report.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Specification

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
