Unification of Abrasion Resistance Standard for Unglazed Tiles and Glazed Tiles

Abstract

Abstract: Abrasion resistance is a key performance of ceramic tiles. At present, GB/T 4100—2015 "Ceramic tiles" requires that different test methods are used for unglazed tiles and glazed tiles. Abrasion resistance of unglazed tiles and glazed tiles were determined by deep abrasion equipment, surface abrasion apparatus and Taber abraser respectively. Whether the same test method can make accurate judgment on ceramic tiles was discussed. The results show that unglazed tiles can be determined by the method of resistance to deep abrasion for unglazed tiles and the method of relative resistance to wear of unglazed ceramic tiles by the Taber abraser. But neither of them is suitable for glazed tiles. Replacing visual evaluation with the loss in mass can get more objective and accurate results in the test method of resistance to surface abrasion for glazed tiles, and applicable to the determination of abrasion resistance for both unglazed tiles and glazed tiles.

Key words: ceramic tile, unglazed tile, glazed tile, abrasion resistance, abrasion loss, standard
