Stainless steel screen color treatment and cleaning

by:KNK     2020-10-17
Stainless steel is formed on the surface of a layer of a very thin and fine and stable solid rich chromium oxide film ( Protective film) To prevent the oxidation of oxygen infiltration, continue, and obtain the ability of corrosion resistant. One but there is some reason, this kind of film is continuously damaged, air or liquid and oxygen atoms will constantly infiltration or metallic iron atom separation out unceasingly, forming loose iron oxide, metal surface rust by constantly. Many in the form of the surface is damaged. Stainless steel screen when carry on the processing of the need for welding process. And the partial melting stainless steel by high temperature melting let together way of processing, the surface of the stainless steel screen welding parts will be oxidized to ferric oxide black and ferroferric oxide, these are very easy to remove black iron oxide, which USES strong acids are not immediately removed. But can not soak for a long time, so will not part of the black iron oxide corrosion bad. So the black iron oxide, all need to deal with the manufacturers, to the customer, it is hard to remove it. Some more responsible factory, will create a black iron oxide to welding parts for removal. Of course, if you don't pay attention to, buy a black iron oxide of the stainless steel screen, or when he has the tools for welding to the black iron oxide, can use the following method to remove. The first is a hammer, get a point knock off slowly. One thing to note is that the stainless steel screen as an ornament, if hit, didn't grasp the strength, it is easy to cause other inevitable scratches, pits, etc. In black iron oxide removal so we must pay attention to grasp the strength. Stainless steel products become more bright techniques: ( 1) Stainless steel screen products surface dust and dirt with soap, weak detergent and warm water wash ( 2) Stainless products trademarks, sticker weak detergent to wash with warm water, difficult binder composition using alcohol or organic solvent scrubbing. Stainless steel welded pipe ( 3) Stainless steel screen, grease, oil, lubricating oil contamination on the surface with a soft cloth wipe up, after use neutral detergent or ammonia solution or use the special detergent to wash. ( 4) Acid adherent surface of stainless steel products, if any, immediately wash with water, then use ammonia solution or neutral fizzy soda solution immersion, use neutral detergent or warm water after washing. ( 5) Stainless steel surface has rainbow lines, and excessive use of detergents or oil is caused, when washing neutral detergent with warm water can wash away. ( 6) Stainless steel welded pipe screen surface contamination caused by rust, available 10% nitric acid or abrasive detergent washing, also can use special washing washing.
