Stainless steel mine screen rust causes and maintenance knowledge
Causes and solutions for rusting of stainless steel ore screens:
The stainless steel wire mesh screen has good corrosion resistance because it forms a passivation film on its surface, so it exists in the form of a more stable oxide in nature. That is to say, stainless steel is used under different conditions, and the degree of oxidation is different. It can be oxidized under certain circumstances. This phenomenon is usually called corrosion. Therefore, stainless steel does not never rust. All metal surfaces exposed to corrosive environments undergo electrification or chemical reactions and are uniformly corroded. In the surface of the passivation film on the surface of the stainless steel ore screen, the part with weak corrosion resistance forms a pitting reaction due to the self-excited reaction, and generates small pores, 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 mine screen, all of which destroys the passivation film on the surface of the stainless steel ore screen. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its beautiful surface and prolong its service life. When cleaning the stainless steel surface, care must be taken not to cause surface scratching. Avoid using bleaching ingredients and abrasive cleaning liquids, steel balls, grinding tools, etc. To remove the washing liquid, rinse the surface with clean water at the end of washing.
Stainless steel mine screen daily maintenance knowledge:
1. The grease, oil and lubricating oil on the surface of the stainless steel mesh are contaminated, wiped clean with a soft cloth, and then cleaned with a neutral detergent or ammonia solution or with a special detergent.
2. The surface of the stainless steel mesh screen is dusty and easy to remove dirt. It can be washed with soap, weak detergent or warm water. The trademark and film of the stainless steel surface are washed with warm water, weak detergent, and the binder component is scrubbed with alcohol or organic solvent (ether, benzene).
3. The rust caused by the dirt on the surface of the stainless steel mesh screen can be washed with 10% nitric acid or grinding detergent, or it can be washed with special washing drugs.
4. The surface of the stainless steel ore screen has rainbow pattern, which is caused by excessive use of detergent or oil. It can be washed with warm water detergent when washing.
5. The surface of the stainless steel ore screen has bleaching agent and various acid adhesions. Rinse immediately with water, then dip with ammonia solution or neutral carbonated soda solution, and wash with neutral detergent or warm water.
