Many of these surface damage in the form of daily life, many are as follows:
1 stainless steel surface deposited dust or heterogeneous metal particles containing other metal elements of attachment, in the moist air, water and attachment of stainless steel, and the two together into a micro cell, causing the electrochemical reaction, the protective film is damaged, called electrochemical corrosion.
2 stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum), in the case of water oxygen, organic acid, long time organic acid on the surface of metal corrosion.
3 stainless steel surface adhesion containing acid, alkali, salt material (such as wall decoration of alkaline water, lime water splash), caused by the localized corrosion.
4 in air pollution (such as containing a large amount of sulfide, carbon dioxide, nitrogen oxide atmosphere), meets the condensed water to form sulfuric acid, nitric acid, acetic acid, liquid, caused by chemical corrosion.
The above conditions can cause surface protective film on stainless steel destruction caused by corrosion. So, in order to ensure a permanent shiny metal surface, no rust, we suggest:
1 must be cleaned regularly on the decorative surface of stainless steel, remove attachments, eliminate trigger modified external factors.
2 coastal areas to use 316 stainless steel, 316 materials can resist corrosion in seawater.
3 markets, some chemical composition of stainless steel pipes can not meet the relevant national standards, amounting to less than 304 material requirements. It can also cause rust, which requires the user to choose reputable manufacturers.
