It can also be a special scrubbing wash. We only use the correct maintenance method, you can extend the use of stainless steel in your life, stick to its clean, bright quantity and beautiful gas.

The weakest part of the passive film on the surface of the stainless steel material forms a pitting reaction due to the self-excited reaction, forming a small hole, and the chloride ion is close to form a strong corrosive solution, which accelerates China The rate of corrosion reaction. Stainless steel filter screens and some stainless steel companies' internal intergranular corrosion cracking, all of us, have a serious effect on the passive film on the surface of stainless steel products.

Therefore, it is necessary to clean and maintain the stainless steel surface in time to maintain its beautiful surface and prolong life. When cleaning the stainless steel surface, be careful not to scratch the surface, avoid using bleach ingredients and abrasive detergents, thread balls, abrasives, etc. to remove the detergent. After washing, rinse the surface with clean water.

What is the damage form of the surface film of the stainless steel wire mesh

Stainless steel mesh with resistance to atmospheric oxidation, that is, stainless steel, also has the capacity of acid, alkali, and salt corrosive media, that is, corrosion. However, the compatibility of its own chemical composition with steel, mixing state, use environmental conditions and type of medium is changed. For example, stainless steel wire, in dry, clean air, it is **** in rust resistance, but it will be transferred to the sea in sea fog that contains a lot of salt, and it will rust quickly; 316 stainless steel wire is A very good result, it is not any stainless steel wire mesh, corrosion and rust in any environment.

The 304 stainless steel mesh produced by the stainless steel mesh factory is a thin, strong and stable chromium oxide film (protective film) that can be formed on its surface to prevent the continuous penetration and oxidation of oxygen atoms and has the ability to resist corrosion. Once the enterprise Due to some social reasons, thin film technology is constantly being destroyed, oxygen atoms in the air or liquid are constantly infiltrated, or iron atoms in other metals are constantly being separated and cultivated. Students form loose iron oxide, and the surface quality of metal materials is constantly changing. Corroded. The forms of destructive activities of the surface film develop in many ways. The following are common problems in daily learning and life.

304 stainless steel mesh or dust adheres to the surface containing other metal particles with different metal elements. In the humid air, the connection grid 304 between the condensed water and the stainless steel is connected to the micro area, causing an electrochemical reaction, the protective film is destroyed, and the electrochemical corrosion.

The surface of the stainless steel wire mesh material can be attached to an organic unified juice (such as melon, soup, sputum, etc.), in the presence of water and oxygen, an organic acid is formed, and the organic acid carries out long-term corrosion and metal processing surface. Acid, alkali, salt and other substances attached to the surface, such as alkaline water, lime splashing water, causing local corrosion.

Stainless steel wire mesh in polluted air (such as the atmosphere contains a lot of sulfide, carbon oxide, nitrogen oxide), condensate water, form sulfuric acid, nitric acid, acetic acid liquid spots, causing chemical corrosion.
