Tile grade
Ceramic tiles are divided into first class, first class, second class, third class and so on. The prices are quite different, please compare them carefully when buying, and pay attention to whether the product packaging is consistent with the physical identification, specifications and color numbers, and whether the product certificate, trademark and quality inspection standards are clear.
Specification size
Standardized products are not only beneficial to construction, but also can enhance the decorative effect. High-quality tiles have small size deviation, neat paving and straight brick joints. When checking, you can put the tiles on a plane, and observe whether the four sides are consistent, whether the four corners are right angles, and the error of side length and side thickness is also under investigation.
difficulty
Hardness is another sign of tile quality. High-quality ceramic tiles should have good toughness and non-fragile characteristics. Scrape each other with the edges and corners of the fragments, and observe the details of the broken parts of the broken fragments to judge the quality of the tiles.
Patterns and colors
Good ceramic tile patterns and patterns should be clear and consistent in color and exquisite in workmanship. Check whether there is color leakage, dislocation, broken line or inconsistent depth.
Color difference problem
Color difference may also occur in the same batch of products, so it is necessary to sample and compare the products in each package when purchasing. Put the tiles in the same type of bricks and observe the degree of color difference. The color difference of high-quality products is very small, the color tone is basically the same, and the color is bright and uniform.
surface finish
High-quality tiles are not only uniform in color, but also up to standard in surface smoothness, regular in periphery and complete in patterns. When buying, take out four or five pieces from a box to see if there are any defects such as color difference, deformation and lack of edges and corners.
