Stone wear tester test requirements and methods

Test Requirements:

Each group contains four samples. The dimensions of the samples should be as follows: length and width are 50 mm ± 0.5 mm, and thickness ranges from 15 mm to 55 mm. The edges of the samples to be worn 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. After cooling to room temperature in a desiccator, the testing should proceed.

Testing Method:

1. Measure the dry mass of the sample with an accuracy of 0.02g. Then place it 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 recommended as the abrasive material. The sample is ground on a grinding disc of 225 mm. After the test, remove the sample and brush off any dust. Measure the weight again with an accuracy of 0.02g.
2. Immerse the sample in water for 1 hour. After removal, wipe the surface with a damp cloth and weigh it. Calculate the bulk density according to GB/T 9966.3-2001. It's important to note that humidity can affect the grinding performance. Higher humidity may lead to a higher grinding rate. Therefore, it is recommended that the test be conducted in an environment with relative humidity between 30% and 40%.
3. After completing the test, clean the surface of the sample thoroughly and cover it with a dust cover to protect it from contamination.

This procedure ensures accurate and consistent results while maintaining the integrity of the samples throughout the process.
