无釉砖和有釉砖耐磨性标准的统一化探析

Unification of Abrasion Resistance Standard for Unglazed Tiles and Glazed Tiles

耐磨性是陶瓷砖的一项关键性能指标,目前GB/T 4100—2015《陶瓷砖》规定无釉砖和有釉砖采用不同的试验方法。利用耐深度磨损试验机、陶瓷砖釉面耐磨试验机和Taber试验机对无釉砖和有釉砖进行耐磨性的测定,研究同一种试验方法是否能同时对两种陶瓷砖作精确的评判。结果表明,无釉砖耐磨深度法和Taber耐磨试验法可通过磨损体积的大小对无釉砖进行耐磨性的测定,但两者都不适合用于有釉砖耐磨性的测定。有釉砖表面耐磨法用磨耗质量大小取代目视评价可得到更客观和精准的结果,可同时用于无釉砖和有釉砖耐磨性的测定。

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.
