“Stainless steel wire mesh is rusty, stainless steel mesh couldn’t be rusty.” In fact, this is a lack of understanding of the one-sided stainless steel misconceptions. Under a certain condition, stainless steel welded wire mesh will be rusty.
Stainless steel wire mesh rely the surface layer to prevent the oxygen atoms to penetrate which is very thin and strong. Then it forms a stability of dense protective film to prevent from oxidation, and access to anti-corrosion ability. However, this ability is conditional. For some reasons, this film was the constant destruction of air or liquid oxygen will continue to infiltrate or metal from the iron atom out of constant analysis, the formation of porousiron oxide, metal surface corrosion also be kept. This surface film in the form of destruction of many more common in daily life are the following categories:
1. There is other metal elements containing dust particles or heterogeneous metal attachments on Stainless steel wire mesh’s surface. In humid air, condensation between fixtures and stainless steel water will allow the two together into a micro-battery to cause power chemical reaction. Then protective film is damaged, we call it electrochemical corrosion.
2. Stainless steel wire mesh surface adhesion organic juice (such as vegetables, soup, sputum, etc.), in the case of water oxygen to form organic acids, organic acids. Corrosion will happen on the metal surface of stainless steel welded wire mesh in the long time.
3. Stainless steel wire mesh surface adhesion containing acid, alkali, salts (such as wall decoration alkaline, lime water splash), causing localized corrosion.
4. Where air pollution (such as with a large number of copper oxide, aluminum oxide, sulfide, nitrogen oxides, carbon dioxide, iron oxide in the atmosphere), the water molecules condensated to form sulfuric acid, nitric acid, acetic acid, oxalic acid solution point, causing Stainless Steel Wire Mesh chemical corrosion.
Situation described above can all get the surface of stainless steel wire mesh rusty and damage to cause corrosion protective film. Therefore, we should strengthen the protection of the surface of stainless steel wire to lengthen it’s best life.
