Stone wear tester test requirements and methods

Test Requirements:

Each group includes four samples. The dimensions should be as follows: length and width of 50 mm ± 0.5 mm, and thickness ranging from 15 mm to 55 mm. The edges of the samples should be rounded with a radius of approximately 0.8 mm.

The samples must be placed in a thermostatic drying oven at 105°C ± 2°C for a certain period and then cooled to room temperature in a desiccator before testing.

Experimental Method:

1. The initial weight of the dried sample is measured with an accuracy of 0.02g. Then, it is placed into the wear testing machine. The abrasive used should conform to GB/T 2479-1996, with a grain size of 0.25mm. White fused alumina is used as the abrasive, and the sample is ground on a grinding disc with a diameter of 225mm. After the test, the sample is cleaned, dust is removed, and the final weight is measured again with the same precision of 0.02g.
2. The sample is immersed in water for 1 hour. After removal, the surface is dried with a damp cloth, and the weight is measured. The bulk density is calculated according to GB/T 9966.3-2001. Since humidity can affect the grinding performance, it's recommended that the test be conducted under a relative humidity of 30% to 40% to ensure consistent results.
3. After the test is completed, the surface of the sample should be cleaned thoroughly, and a dust cover should be placed over it to prevent contamination.

This detailed procedure ensures accurate and reliable results, helping to evaluate the wear resistance of stone materials effectively.
