The use of stainless steel filters has become more extensive with economic development. People are closely related to stainless steel in their daily lives, but many people do not know much about the performance of stainless steel meshes, and they know less about stainless steel maintenance. Many people think that stainless steel will never rust, and stainless steel has good corrosion resistance. The reason is that a passive film is formed on the surface, which exists in the form of a more stable oxide in nature. That is to say, although the stainless steel has different oxidation levels according to different use conditions, it is eventually oxidized. This phenomenon is usually called corrosion.
Wire Mesh Strainers
Wire mesh strainers supplier introduces you to the maintenance of stainless steel filters:
If the surface of the stainless steel wire mesh has dust and dirt is easy to remove, it can be washed with soap, weak detergent or warm water. The trademarks and films on the surface of the stainless steel filter screen should be washed with warm water and weak detergent. The adhesive ingredients should be scrubbed with alcohol or organic solvents (ether, benzene). Grease, oil, and lubricating oil on the surface of stainless steel should be cleaned with a soft cloth, and then cleaned with neutral detergent or ammonia solution or with special detergent.
Wire mesh strainers have bleach and various acids attached to the surface. Immediately rinse with water, then rinse with ammonia solution or neutral carbonated soda solution, and wash with neutral detergent or warm water. The surface of the stainless steel screen has rainbow patterns, which is caused by the excessive use of detergent or oil. It can be washed away with warm detergent in warm water. The rust caused by the dirt on the stainless steel surface can be washed with 10% nitric acid or abrasive detergent, or with special cleaning chemicals. As long as we use the correct maintenance method, we can extend the service life of stainless steel and maintain its clean, bright and gorgeous style.
The parts with weak corrosion resistance in the passivation film on the surface of the stainless steel filter screen form pitting corrosion due to the self-excitation reaction, forming small holes, and the proximity of chloride ions forms a strong corrosive solution to accelerate the corrosion reaction. speed. There are also intergranular corrosion cracks inside the stainless steel, all of which have a destructive effect on the passivation film on the surface of the stainless steel. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life. When cleaning the surface of stainless steel, care must be taken not to scratch the surface, avoid the use of bleaching ingredients and abrasives, steel balls, grinding tools, etc. In order to remove the cleaning fluid, rinse the surface with clean water at the end of the washing.
