Stainless steel plate
1.Stainless steel surface accumulation contains other metal elements of dust or heterogeneous metal particles of the attachment, in the moist air, adhesion and stainless steel condensate, the two into a micro-battery, triggered an electrochemical reaction, the protection film was damaged, called electrochemical corrosion.
2. Stainless steel surface adhesion organic juice (such as melon vegetables, noodle soup, phlegm, etc.), in the case of water oxygen, constitute organic acid, long time organic acid on the metal surface corrosion.
3. Stainless steel surface adhesion contains acid, alkali, salt substances (such as decoration walls of alkali water, lime water splash), causing local corrosion. 4. In the polluted air (such as the atmosphere containing a large amount of sulfide, oxidized carbon, nitrogen oxides), in case of condensate, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion above can cause the damage of stainless steel surface protective film caused by corrosion.
