How much do you know about stainless steel filter maintenance

With the development of economy, the application of Stainless Steel Filter Screen becomes more and more extensive. People are closely related to stainless steel in ordinary days, but many people don't know much about the function of stainless steel, and they know less about the protection and maintenance of stainless steel. Many people think that stainless steel will never rust, and stainless steel has good corrosion resistance. The reason is that the surface forms a passivation film. In nature, it exists in a more stable oxide shape. That is to say, although stainless steel is oxidized in different conditions and in different degrees, it is oxidized eventually. This appearance is generally called corrosion.

Stainless steel with dust on the surface and easy to remove dirt can be washed with soap, weak detergent or warm water. The trademark and film on the surface of stainless steel shall be washed with warm water and weak detergent. The adhesive composition shall be scrubbed with alcohol or organic solvent (ether and benzene). The grease, oil and smooth oil on the surface of stainless steel shall be cleaned with soft cloth. After that, use neutral detergent or ammonia solution or special detergent for cleaning.
The surface of Stainless Steel Filter Screen is attached with bleach and various acids. Immediately wash it with water, then wash it with ammonia solution or neutral soda carbonate solution, and wash it with neutral detergent or warm water. There are rainbow lines on the surface of Stainless Steel Screen. It is caused by excessive use of detergent or oil. When washing, it can be washed away with warm water neutral detergent. Rust caused by dirt on the surface of stainless steel can be washed with 10% nitric acid or abrasive detergent, or with special detergent. As long as we use accurate maintenance methods, we can extend the service life of stainless steel, adhere to its clean, bright and rich bearing.

The parts with weak corrosion resistance in passivation film on the surface of stainless steel form pitting response due to self-excited response, forming small holes, and close to chloride ions, forming a strong corrosive solution, accelerating the speed of corrosion response. There are also intergranular corrosion cracking in stainless steel, all of which will damage the passivation film on the surface of stainless steel. Therefore, it is necessary to clean and maintain the stainless steel surface regularly to maintain its rich appearance and extend its service life. When cleaning the surface of stainless steel, it is necessary to pay attention not to scratch the surface, to prevent the use of bleaching ingredients and abrasives, such as cleaning fluid, steel wire ball, grinding things, etc. to remove the cleaning fluid, wash the surface with clean water at the end of cleaning.
