Description
Technical Field
[0001] The utility model belongs to the technical field of tile detection, and particularly relates to a tile wear resistance testing machine. Background Art
[0002] In the building materials industry, ceramic tiles are widely used as decorative materials, and their wear resistance is a key indicator of their quality and service life. A tile's wear resistance not only affects its durability and aesthetics during use but also directly influences consumer purchasing decisions and market competitiveness. Therefore, testing ceramic tiles for wear resistance is a critical step in ensuring their quality.
[0003] Traditional tile wear testers often employ simple mechanical structures, such as using a fixed grinding wheel to perform friction tests on the tile surface. However, this testing method has numerous drawbacks. First, the tile clamping method is often unstable, prone to slippage or loosening, resulting in inaccurate test results. Furthermore, traditional testing machines have limitations in pressure control. The wear resistance of a tile is closely related to the pressure it is subjected to. If the grinding wheel applies inconsistent pressure to the front and back tiles during grinding, the test results will not accurately reflect the tile's true wear resistance. Utility Model Content
