Description

Technical Field

[0002] Industrial coating resin testing refers to a series of performance tests on the resin coating structure coated on the surface of the workpiece, and the salt spray test is mainly aimed at the corrosion resistance test of the workpiece surface. It is an environmental test that uses artificial simulated salt spray environment conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials. It is mainly divided into two categories, one is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a test equipment with a certain volume space - the salt spray test chamber, and uses artificial methods in its volume space to create a salt spray environment to assess the salt spray corrosion resistance of the product.
