Magnet Salt Spray Tester

The salt spray test is an environmental test that mainly uses the artificial simulated salt spray environmental conditions created by the salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into neutral salt spray and acidic salt spray. The difference is that The criteria to be met are different from the test methods, also known as "NSS" and "CASS" tests. The sintered NdFeB is tested for neutral salt spray. According to the national standard, the continuous spray test method is adopted. The test conditions are: 35℃±2℃, 5%±1% NaCl solution (mass fraction), and the pH of the salt spray sedimentation solution is 6.5 -7.2 between. The salt spray test includes 24H, 48H, 72H, etc., and will also meet different salt spray durations according to the actual needs of the product. During the experiment, if the coating is darkened and blackened, it is qualified, and yellow rust, blistering, cracks, falling off, and chalking are found to be unqualified.
