Advantages and weaknesses of floor tiles

(1) The quality inspection certificate and quality inspection report of the product should be requested from the dealer.

(2) Conduct visual inspection at the site to observe whether the product has obvious quality defects such as lack of sleeves, spots, cracks, shafting, and corrugation. The above defects must not be selected.

(3) Listening to the sound: When tapping with a hard object, the crisper the sound, the higher the degree of porcelain and the better the quality. You can also use the left thumb, forefinger and middle finger to clip the corner of the tile and hang it down easily. Use your right index finger to tap the middle and lower part of the tile. For example, the sound is clear and pleasing to the top, such as dull sound and turbidity.

(4) Drip test: Water droplets can be placed on the back of the tile to see how fast the water is infiltrated. Generally speaking, the slower the water absorption, the higher the density of the tile; on the contrary, the faster the water absorption, the thinner the density, the inherent quality. The former is excellent.

(5) Detection by hand. After the two bricks are clamped by fingers, they collide with each other, and the sound is crisp and loud, which is a qualified product. The sound is low and dull, and there must be inherent quality defects.

(6) Discrimination of color difference: Since the number of wall tiles purchased at one time is large, if there is obvious color difference between multiple packages, the decoration effect is greatly affected, and the production of all packages is required.

Sampling comparison of products, observing the change of chromatic aberration, the color difference can not be selected.

(7) Ruler: The higher the accuracy of the length of the tile, the better the effect after paving. Buying high-quality tiles is not only easy to construct, but also saves working hours and accessories. Measuring the size of each tile with a tape measure, the product with a size error of more than 0.5 mm and a flatness of more than 0.1 mm not only increases the difficulty of construction, but also has poor effect after decoration and cannot be used for engineering.
