How can stainless steel prevent rust?
In daily life, stainless steel screw fasteners are common, in use process, rust is a common phenomenon, but also let us worry things, it will not only affect the appearance, at the same time will affect the performance of stainless steel screws.
Therefore, we must pay attention to the main points in the process of using stainless steel screws:
1 stainless steel screws, the surface adhesion of organic juice (such as vegetables, soup, sputum), oxygen in the water under the circumstances, a long time, organic acid, organic acid on the surface of metal corrosion.
2, or dust particles heterogeneous metal attachments, in the humid air, condensed water attachment and stainless steel screws, the two together into a micro battery, causing the electrochemical reaction, the film has been destroyed, called electrochemical corrosion.
3, in polluted air (such as containing large amounts of sulfide, carbon dioxide and nitrogen oxides in the atmosphere), in case of condensation water, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.
4, stainless steel surface adhesion contains acid, alkali, salt substances (such as decoration wall caustic soda, lime water splash), cause local corrosion.
