Why Does The Stainless Steel Filter Also Rust?
Plain Weave Wire Mesh Causes of rust The anti-modification ability of stainless steel relies on a very thin, strong, dense, and stable chromium-rich oxide film (protective film) formed on its surface. It can effectively prevent the continuous penetration and oxidation of oxygen atoms. However, once the film is continuously destroyed for some reason, the metal surface will be continuously rusted. The oxygen atoms in the air or liquid will continue to infiltrate or the iron atoms in the metal will continue to separate out, causing loose iron oxide to form on the surface of the metal. Common types of rust in life 1. The surface of stainless steel filter mesh adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time. 2. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide),
