Test the model should bear the following test
:When a scratch test is performed, the scratches should pass the five pairs of conductive parts. It is the largest part of the potential gradient during the test.
When a scratch test is performed, the hard -hard steel needle is used to scratch. Polish, the inverted radius is 0. 25 mm ± 0.02 mm.
When a scratch -resistant test machine is used for scratch test, it should be in the plane that is perpendicular to the edge of the conductor as required, 20mm at 20mm as required, 20mm at 20mm as required, 20mm at 20mm. Speed at ± 5mm/s. A proper load should be added to the steel needle to enable the steel needle to apply 10 n ± 0.5 n in the direction of the axis. The scratches should be at least 5mm, and the edge of the sample should be at least 5mm apart from the edge of the sample. Essence >After the test, the coating must not be loosened or stabbed, and it should be able to withstand the prescribed anti -electricity strength test between the wires. In the metal core printing board, the substrate should be one of the wires.
1. Product introduction:
Also known as a balanced scraper with a scratch resistance test machine, needle scratch -resistant test machine, scratch resistance test machine adapted to the scratch -resistant scratch resistance of single coating or composite coating system Performance assessment. Whether the ball -shaped steel needle is cut through the coating or the large load of the coating of the coating to evaluate the scratch ability of the coating. > 2. Product overview:
