Stainless steel HEX bolt in use should also pay attention to his own maintenance, after all, he will also have rust, so we want to maintain stainless steel HEX bolt, it is necessary to understand several ways of his rust: 1. The attachment of dust or different metal particles, in the humid air, the attachment and the condensate of stainless steel screws, the two connected into a micro battery, triggered an electrochemical reaction, the protective film is damaged, called electrochemical corrosion.
2 stainless steel screw surface adhesion organic juice (such as vegetables, soup, sputum, etc.), in the case of water and oxygen, organic acid, organic acid corrosion of metal surface for a long time.
3 stainless steel surface adhesion contains acid, alkali, salt substances (such as decoration of the wall of alkali water, stone ash water splash), cause local corrosion.
4. In the polluted air (such as the atmosphere containing a large number of sulfide, carbon oxide, nitrogen oxide), when condensed water is encountered, sulfuric acid, nitric acid, acetic acid liquid point is formed, causing chemical corrosion.
The above situation can cause corrosion of stainless steel screw surface protective film damage. Therefore, in order to ensure that the stainless steel screw surface permanent bright, not rust. We have to clean the surface. Passivation and other processing.
To sum up, when we use stainless steel screws in our daily work and life, we must pay attention to the above 4 points to prevent the rust of stainless steel screws.
