Causes and Solutions of Rusty Stainless Steel Screens

The stainless steel screen has good corrosion resistance because it forms a passivation film on the surface, so it exists in the form of more stable oxides in nature. Wholesale stainless steel cable mesh, according to different conditions of use, the degree of oxidation of stainless steel is not the same and can be oxidized in a specific environment. This phenomenon is often called corrosion. Therefore, stainless steel screens will not always rust. Electrochemical reaction or chemical reaction occurs on all metal surfaces exposed in the corrosive environment and is uniformly corroded. Corrosion resistance in the passivation film on the surface of the stainless steel ore screen is weak. Due to the self-excitation reaction, pitting reaction is formed and small holes are formed. Together with chloride ions, a strong corrosive solution is formed and the corrosion reaction is accelerated. speed. There is also an intergranular corrosion cracking inside the screen of the mine, all of which have a destructive effect on the passivation film on the surface of the stainless steel screen. Therefore, the stainless steel mesh surface must be regularly cleaned and maintained to maintain its beautiful surface and prolong its service life. When cleaning the surface of stainless steel, care must be taken not to scratch the surface, to avoid the use of bleaching components and abrasive cleaning liquids, steel balls, abrasive tools, etc. To remove the washing liquid, rinse the surface with clean water at the end of washing.
