Stainless steel waiting chair acidification meet what problem
Stainless steel common acidizing waiting chair.
Deposited on the surface of the stainless steel contain other metal elements of attachments, or heterogeneous metal particles of dust in the humid air, attachments and stainless steel, the condensed water between the both together as a micro battery, can produce electrochemical reaction, protective film, called the electrochemical corrosion.
Stainless steel surface adhesion organic juice (
Such as vegetables, noodle soup, sputum, etc. )
, in the case of oxygen by the water, organic acid, organic acid to for a long time and are on the surface of the metal corrosion.
Stainless steel surface adhesion containing acid, alkali, salt substances (
Like to decorate the walls of caustic soda and lime water splash)
, cause local corrosion.
In the pollution of air,
If they contain a lot of sulfur, carbon oxide, nitrogen oxide atmosphere)
, meet a condensation water, formation of sulfuric acid, nitric acid, acetic acid liquid, caused by chemical etching.
