With the economic development, the use of stainless steel filters is becoming more and more common. People are closely related to stainless steel mesh in daily life. However, many people know very little about the performance of stainless steel, and very little about the maintenance of stainless steel. Many people think that stainless steel will never rust, but in fact, stainless steel has good rust resistance. This is due to the formation of a passivation film on the outside. This passivation film exists in nature as a more stable oxide.

In other words, although stainless steel has different oxidation levels depending on the operating conditions, it is eventually oxidized. This phenomenon is usually called corrosion. The stainless steel filter has dust on the surface and is easy to descale. You can use soap, weak detergent or warm water. Wash the stainless steel surface trademark, paste the film, wash with warm water, weak detergent, adhesive composition, use alcohol or organic solvents (ether, benzene) to scrub the grease on the stainless steel surface.

If engine oil and smooth oil are contaminated, clean it with a soft cloth. Later, use neutral detergent or ammonia or special detergent to clean the bleach and various acids on the surface of stainless steel. Rinse immediately with water, and soak carbonated soda with ammonia solution or neutral water. , Use neutral detergent or hot water for washing. Stainless steel wire mesh has rainbow patterns on the surface of stainless steel wire mesh. It is formed by excessive use of detergent or oil. It can be washed with warm water and neutral detergent.

　　The corrosion caused by dirt on the surface of stainless steel can be cleaned with 10% nitric acid or abrasive cleaning agent, or with special cleaning agent. As long as we adopt correct maintenance methods, we can prolong the service life of stainless steel and adhere to its clean, bright and gorgeous style. The weak corrosion resistance of the passive film on the surface of stainless steel is due to the self-excited reaction, which leads to the formation of pitting corrosion, the formation of pores and the proximity of chloride ions to form a strong corrosive solution, thereby accelerating the corrosion reaction.

　　 The stainless steel filter screen and the stainless steel inner weld are corroded and cracked, all of which destroy the passive film on the surface of the stainless steel. Therefore, the stainless steel surface must be cleaned and maintained regularly to maintain its gorgeous appearance and extend its service life. When cleaning the stainless steel surface, be careful not to scratch, and prevent the use of bleach and abrasive detergent, steel balls, abrasive tools, etc., to remove the detergent, and rinse the surface with water.
