With the development of economy, the application of stainless steel screen has become more and more extensive. People are closely related to stainless steel in their daily life, but many people do not know much about the function of stainless steel, less is known about the protection and maintenance of stainless steel. Many people think that stainless steel is never rust, in fact, stainless steel corrosion resistance is outstanding. The reason is that the surface forms a passivation film, which in nature takes the shape of a more stable oxide. That is to say, stainless steel, although by the use of different conditions, the degree of oxidation is not the same, this phenomenon is generally called corrosion. Stainless steel filter screen stainless steel appearance of dust and easy to remove dirt, can be used soap, weak scrub agent or warm water wash. Stainless steel exterior trademark, film, with warm water, weak scrub agent to wash, adhesive ingredients, use of alcohol or organic solvents (ether, benzene) wipe. Stainless steel appearance of grease, oil, oil pollution, clean with a soft cloth, after using neutral scrub agent or ammonia solution or use a special scrub agent cleaning. Stainless steel surface bleach and a variety of acid adhesion, immediately washed with water, then with ammonia solution or neutral soda water solution, with neutral scrub agent or warm water scrub. Stainless steel screen stainless steel screen appearance has rainbow pattern, is caused by excessive use of scrub agent or oil, scrub with warm water neutral scrub agent can be washed off.
Stainless steel surface dirt caused by rust, can be used 10% nitric acid or grinding scrub scrub agent scrub, also can be used to scrub special drugs scrub. As long as we use the correct maintenance method, we can extend the service life of stainless steel, adhere to its clean, bright, rich bearing. In the passivation film on stainless steel surface, the weak corrosion resistance part forms pitting reaction because of self-excitation reaction, which forms small holes, and the chloride ion is close to it, thus forming a very strong corrosive solution, speed up the corrosion response. Stainless steel filter mesh and stainless steel internal intergranular corrosion cracking, all of these, on the stainless steel surface passivation film are the effect of damage. Therefore, it is necessary to carry out regular cleaning and maintenance of stainless steel filter screen in order to adhere to its rich appearance and extend service life. When cleaning the appearance of stainless steel, it is necessary to pay attention to the appearance of scratch-free phenomenon, to prevent the use of bleach ingredients and abrasive cleaning fluid, steel ball, grinding things, etc. , in order to remove the cleaning fluid, at the end of the Wash and then use clean water to wash the appearance.
