The sample is fixed on the test bench, the top of the scraper bar is fixed with a highly polished scraper head made of tungsten carbide material, with a diameter of 1mm or 7mm, and the scraper bar Fix the weight at the other end, and determine the installation position, quantity and load of the scraper bars according to the sample size and test requirements. The scraper distance is generally set to 100mm - 200mm, and the scraper speed is 100mm / s. Visually inspect the scratches under the sunlight of the nooclear sky or D65 standard light source to evaluate the scratch resistance of the material.
