Many forms of surface film damaged

Stainless steel is a very thin layer formed on the surface and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, this film was constantly destroyed, air or liquid oxygen atoms will continue to infiltrate or metal atoms of iron to keep out from the loose formation of iron oxide, the metal surface will be continuously corroded. This form of surface film is damaged in many ways:

1, the surface of stainless steel deposited dust or heterogeneous metal particles containing other metal elements of the attachment, in the humid air, condensed water and adhesion between the stainless steel, the two together into a micro battery, causing the electrochemical reaction, the film has been destroyed, called electrochemical corrosion.

2, stainless steel 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. E-BON the most excellent stainless steel company, which provide you with stainless steel mug manufacturer china.

3, stainless steel surface adhesion contains acid, alkali, salt substances (such as decoration wall caustic soda, lime water splash), cause local corrosion.

4, 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.
