Multi Finger Scratch Tester is an efficient and accurate tester for measuring flat products such as travel cases, carpets, cardboard, clothing, glass, plastic coatings, tiles, etc. It is used to evaluate the abrasion resistance of materials, including mass loss, thickness loss and light transmission rate.
Friction resistance tester test principle.
The material to be tested is placed on the turntable, and two abrasive wheels are pressed on the material with a certain weight to make it subject to abrasion. The abrasive wheels rotate with the rotating surface of the sample disc to produce relative motion and abrasion, and the offset of the abrasive wheel shaft relative to the rotating axis of the turntable during rotation produces a slippery motion, thus abrading the material.
Simulation of real test conditions
：
For different material properties, a variety of different abrasive media and accessories can be selected for different tests; in addition, the test can be repeated on the same point of a material, as thick as possible about 0.5" of material broken or worn off; in addition, two rotational speeds (60, 72 rpm), 0-50,000 rpm (can be quickly set to 100, 500, 1000 or 2500 rpm) and 3 types of load.
Finger Scratch Tester Advantages
：
This Multi Finger Scratch Tester has a unique abrasion process, realistic simulation conditions, vacuum cleaner to remove abrasive chips, which can ensure the stability and accuracy of the test, to achieve reliable test results, and the selection of the selected abrasive wheel selection by strict quality control, high quality, good stability.
