1, see the grade logo
Tiles are divided into five grades. There are distinctions between excellent products, first-class products, second-grade products, third-grade products, and other foreign products. Because the price difference is large, they need to be carefully compared. In addition, in the purchase, we must pay attention to the tile and the packaging box on the logo and specifications, color number is consistent, product certification, trademarks and quality inspection standards are clear.

The standard size is not only conducive to construction, but also reflects the decorative effect. Good deviation of specification is small, uniform and uniform after laying, brick seams straight, and good decorative effect. For products with a size error of more than 0.5 mm and a flatness of more than 0.1 mm, unfairness will increase the difficulty of construction and the effect of decoration will be poor.
Whether the size meets the standard can be judged by the target. Place the bricks on a flat surface and see if the four sides are exactly in line with the flat surface. Also, see if the four corners of the tile are all right-angled. The ceramic tiles have no defects such as bumps, bumps, and warping angles. The error of the side length is no more than 0.2---0.3 mm, and the thickness error is no more than 0.1 mm.
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. With a tape measure, there is no difference in the size of each tile, and the highest precision is the top grade.

3, hardness
Tiles with good hardness, toughness, not crushed for the top grade. Scratches between the tile corners and tiles to see whether the broken pieces are broken or loose, whether hard, brittle, or soft, whether it is left scratches or scattered powder, if the former is the top grade, the latter is the top quality. difference.
The criterion of whether the size is the key to judging whether the tile is good or bad is to use a tape measure or a caliper to measure whether the diagonal line and the four sides of the tile are uniform in size and thickness. The good tile has a crisp sound, indicating that the porcelain content is high. If the sound "squeaks" with a crack, it means there is a crack in the brick. A good tile, the master installation is also convenient for construction, and the effect of installation is also standardized.
