This kind of situation generally occurs in the decoration site or in the production enterprises engaged in the chemical industry. The stainless steel perforated mesh taboo is in contact with acid, alkali, salt and other substances. In the ordinary decoration process of people, the paint of the paint and the alkaline water on the wall of the decoration may cause local corrosion of the stainless steel perforated mesh. They are caused by the alkaline and acidic substances they contain. Generally speaking, when the alkaline value and acidic value of the surface of the stainless steel perforated mesh reach a certain level, the chromium-rich oxide film attached to the surface will be corroded by itself, resulting in damage to the stability of the product. It can also be clearly seen that this corrosion state is the most serious among various corrosion states at present. However, what are the methods to prevent chemical corrosion? 1. The passivation treatment of stainless steel perforated mesh can be treated with cold concentrated nitric acid. 2. Electroplating of stainless steel perforated mesh: Electroplating treatment is the most effective, which can make the product itself form a thin zinc layer, thus effectively preventing the attack of chemical corrosion. 3. Surface treatment of stainless steel perforated mesh: Brushing the isolation layer is the most effective method at present. Brushing a layer of paint on the stainless steel surface can not only improve the aesthetics of the product, but also reduce chemical corrosion to a certain extent Occurrence probability of the state.
