First, the color difference: the same kind of name between the brick and the brick there is no difference between the depth of the face is very important. Because the number of wall tiles purchased at one time is large, if there is obvious color difference between multiple packages, the decoration effect is very affected. It is necessary to sample and compare all the packaged products, observe the change of color difference, and the color difference can not be selected. Therefore, when purchasing, even the same type of tile should look at the same color number on the package.
Second, the size and size of the product should be tested one by one. The product with a dimensional error greater than 0.5 mm and a flatness greater than 0.1 mm will not only increase the difficulty of construction, but also have poor effect after renovation and cannot be used for engineering.
Third, deformation: such as the edge is not straight, warp and so on.
Fourth, whether the brick surface is flat, whether there are pinholes with uneven thickness, and the tile can be tapped to hear whether the sound is crisp or not. The more fragile the sound, the higher the texture density and the better the hardness of the tile. You can try to scrape the surface of the brick with a hard object. If there is a scratch, it means that the glaze is insufficient. After the glaze on the surface is polished, the brick surface is easily stained and difficult to clean.
