Discussion on the uniformity of wear resistance test methods for glazed ceramic tile and unglazed ceramic tile

Ceramic tiles are widely used as building materials in indoor and outdoor decoration projects. When used as floor tiles, the wear resistance of ceramic tiles is a very important performance index, which is related to the quality and service life of ceramic tiles. In the national standards, the test methods used for glazed ceramic tiles and unglazed ceramic tiles are not consistent. Based on the existing national standards, this article is based on the existing national standards. The two types of ceramic tile wear resistance evaluation methods，and glazed surface loss experiments are carried out on glazed and unglazed ceramic tiles. After the performance test, by comparing the experimental results of the three methods, it is discussed whether the current ceramic tile wears resistance test method can be used to detect the two ceramic tiles at the same time.
