Germany byk 5780 balance scraper Ring attachment and scratch hardness test device Place of production: Germany
Balancing rod attachment and scratch hardness tester
It is used to test the adhesion and hardness (scratch hardness) test on the surface of coatings and various materials.The level of adhesion of the coating to the bottom material
Relative to the series of coating model
The instrument has a fulcrum with a fulcrum, a 45 -degree arm support on the pole. Essence Rotate a cam to lift the arm on the rod. The model seat can be moved on the pulley to move the experimental model in the direction of the fixed arm.
The adhesion test of the scraping rod
The rod used to do the adhesion test of the scraper is a drill rod with a diameter of 0.0625 inches, the front end of the front end Bend into a 180 -degree ring with 0.256 inches from the ring diameter. This part is hardened and polished and chrome -plated. There is a set of 12 long slots and storage racks that are provided at the same time as the test. When the adhesion test is performed, the weight is usually increased by 10 kilograms per 500 grams to ZUI.
The hardness test of the scratch
Move the test model in the direction of the ring, the different units of grams are applied on the ring. With the load, the small load of ZUI can slide the membrane until the bottom material is to determine the resistance of the coating. During the hardness (resistance) test, the weight is increased from 10 grams per 10 grams to 12 kg.
