How to ensure that the stainless steel wire mesh shaker never rusts?
In the acid-base environment to ensure that the stainless steel wire mesh does not rust, the first choice is to use high-quality stainless steel wire. The corrosion resistance of the stainless steel mesh is mainly due to the nickel content. The higher the nickel content, the more resistant to corrosion. Stainless steel mesh is divided into nickel-free, two nickel, four nickel, 304, 316, 316L and other materials, 316L has the highest corrosion resistance. Another reason for ensuring that the stainless steel mesh shaker does not rust is that a passivation film is formed on the surface, which is in the form of a more stable oxide in nature. That is to say, the stainless steel mesh is different in use conditions, the degree of oxidation is different, and it can be oxidized under certain circumstances. This phenomenon is usually called corrosion. Therefore, stainless steel mesh does not never rust. All metal surfaces exposed to corrosive environments undergo electrification or chemical reactions and are uniformly corroded. In the part of the passivation film of the stainless steel mesh vibrating screen, the corrosion resistance is weak, and the pitting reaction is formed by the self-excited reaction, and small pores are formed, and the chloride ions are close to form a strong corrosive solution to accelerate the corrosion reaction. speed. There is also intergranular corrosion cracking inside the vibrating screen, all of which destroys the passivation film on the surface of the stainless steel mesh vibrating screen. Therefore, the surface of the stainless steel mesh must be regularly cleaned and maintained to maintain its beautiful surface and prolong its service life. When cleaning the surface of the stainless steel mesh, care must be taken not to cause surface scratching. Avoid the use of bleaching ingredients and abrasive washing liquids, steel balls, grinding tools, etc., in order to remove the washing liquid, rinse the surface with clean water at the end of washing.
Pay attention to the following points in the maintenance method of stainless steel mesh vibrating screen. The first is the rust caused by the dirt on the surface of the stainless steel mesh. It can be washed with 10% nitric acid or grinding detergent, or it can be washed with special washing drugs. Second, the stainless steel mesh vibrating screen has a rainbow pattern on the surface, which is caused by excessive use of detergent or oil. It can be washed with warm water detergent when washing. Third, the surface of the stainless steel mesh has bleaching agent and various acid adhesions. Rinse immediately with water, dip with ammonia solution or neutral carbonated soda solution, and wash with neutral detergent or warm water. Fourth, the surface of the stainless steel mesh is contaminated with grease, oil and lubricating oil. Wipe it with a soft cloth and then clean it with a neutral detergent or ammonia solution or with a special detergent. The fifth is to remove the dirt on the stainless steel net in time. The stainless steel mesh can not be deformed and the passivation film is destroyed. Scrub with warm water or organic solvent.
