TestProcedures
1. Sample Installation
Fix the temperature and humidity treated sample onto the rotating test head, adjusting the arch height to 5-8 mm.
2. Sandpaper Fixation
Use the pressure plate clamp to install the sandpaper onto the lower surface of the pressure plate, ensuring it is flat and wrinkle-free.
3. Parameter Setting
Input parameters such as rotation speed, number of friction cycles, and pressure value via the touchscreen.
4. Test Start
Lower the pressure plate to bring the sandpaper into contact with the sample, beginning the friction test.
5. Result Evaluation
After the test, observe the sample's mass loss and the formation of holes to quantify its abrasion resistance.
