ISO 12137-2-1997 Standard The definition of scratching is the scratch or other defects caused by the stipulation of the painting film on the surface of the paint film. The scratching involves a large range of lacquer film surface defects, such as short scratches such as the surface scratches on the surface of the paint film caused by the nail or car washing brush. These defects can be divided into plastic metamorphosis; surface flaws; surface scratches; internal fissure; scratch resistance test machines conform to the above types.
The principle of the standard of ISO 12137-2-1997 is to apply the test product or system to a flat test board with a uniform thickness. After the coating is dry/curing, the injury resistance is determined by pushing the test board under the needle. The padding of the first part is arc (ring or ring -shaped), and the needle is pressed down at 45 ° to the test board to increase the load on the needle level by step by step. 0.25kg or 0. 1kg) until the coating is scratched. The padding of the second part is a spire, pressed vertically down to the test board, and continuously increases the load on the needle (0 ~ 50g, 0 ~ 100g, and 0 ~ 200g) through the electronic device until Stir -scratched.
1. Product introduction:
Full automatic resistance Scraping test machine also known as scratch instrument, scratch tester, the evaluation of scratch resistance for single coating or composite coating system that adapts to the insulation color coating plate. The maximum load of the broken coating or steel needle has not scratched the coating to evaluate the scratching ability of the coating. >
2. Product overview:
