Wear resistance test and standard analysis of ceramic tiles

The ceramic glaze wear resistance tester is designed and manufactured in accordance with GB / T3810.7-2016 Standards of surface wear resistance of ceramic Glazed Tiles. Place a certain amount of abrasive on the ceramic tile glaze, grind the abrasive on the glaze, and visually compare the the glaze of the sample.

Definition

The wear resistance of Ceramic Tiles refers to the anti-wear performance of ceramic tiles, which is evaluated by the volume of grinding pit under specified friction conditions (unglazed tiles) or the number of revolutions with visible wear marks (glazed tiles). Floor tiles need to be tested for wear resistance, while wall tiles do not.

Evaluation method of wear resistance of unglazed tiles

The test method standard for the wear resistance of unglazed tiles is GB / T 3810.6-2006 test methods for ceramic tiles Part 6: Determination of wear resistance of unglazed tiles. Its principle is that under specified conditions and with abrasive, the grinding pit is generated by the rotation of friction steel wheel on the front of the tile, and the wear resistance of unglazed tiles is measured by the length of the measured grinding pit.Calculate and report the average pit volume of 5 samples (each sample has two tangent pits, a total of 10 pits).

The test mechanism of JC / T 945-2005 permeable brick and GB / T 23458-2009 ceramic brick for square is similar to that of GB / t3810.6-2006, but the test methods and performance indexes are different.

Evaluation method of wear resistance of glazed tiles

The test method standard for the wear resistance of glazed tiles is GB / T 3810.7-2006 test methods for ceramic tiles - Part 7: Determination of the surface wear resistance of glazed tiles. Its principle is: place a certain particle graded grinding steel ball, grinding medium (No. 80 corundum) and a certain amount of demonized water or distilled water on the glaze, rotate and grind according to the specified test method, Observe and compare the worn samples with the non worn samples, and evaluate the wear resistance of glazed tiles by whether visible wear traces can be observed. The samples are classified according to table 1 and are divided into 5 levels. Among them, for the samples without visible wear trace after passing the 12000 revolution test ("pass" means that after the 12000 revolution test, the visible wear trace cannot be observed according to the specified method), the pollution resistance test must be carried out according to GB / T 3810.14-2006 test methods for ceramic tiles Part 14 determination of pollution resistance. If any method (a, B, C or D) listed in GB / T 3810.14 is followed, the pollution cannot be wiped off, and the wear resistance is rated as grade 4 (the function is to grade by distinguishing the severity of wear).
