1. Use Rockwell Hardness Tester: Rockwell Hardness Tester is a commonly used hardness tester, which can measure the hardness of emery floor. The specific steps are as follows:
-Prepare a Rockwell Hardness Tester, and set and calibrate it correctly according to the equipment instructions.
-Choose a representative position on the emery floor to ensure that the surface is smooth, clean and free of impurities.
-Place the spherical indenter (usually 1.6 mm or 3.2 mm) on the floor surface and apply a certain pressure.
-Read the reading on Rockwell Hardness Meter, which shows the hardness of emery ground.
2. Glossmeter measurement: Glossmeter can also be used to detect the hardness of emery ground. Hardness and luster usually have a certain correlation, and higher luster usually corresponds to higher surface hardness.
-Prepare a gloss meter, and set and calibrate it correctly according to the equipment instructions.
-Select a representative area on the surface of emery terrace.
-Place the glossmeter probe on the surface of the selected area and press the trigger button to measure the gloss.
-Read the reading on the gloss meter, which can be used to indicate the hardness of the emery floor.
These methods can provide a rough evaluation of the hardness of emery ground. Please note that if a more accurate and precise hardness test is needed, it may be necessary to use other professional equipment or require a professional testing institution to conduct the test.
