No matter what material is used in the manufacture of the cabinet, due to the humid weather, the cabinet will rust after a long time of use. So, what are the reasons for the corrosion of outdoor cabinets? This requires us to pay attention to some of the problems mentioned below in our daily life. Let's understand them together.
1. Surface pollution: the oil, dust, acid, alkali, salt, etc. on the surface of outdoor cabinet will be transformed into corrosive medium under certain conditions. Then, it reacts with some components of stainless steel parts to produce chemical corrosion and rust.
2. Surface scratch: the damage of various scratches to the passive film of outdoor cabinet reduces the protection ability of stainless steel. Therefore, it is easy to react with chemical medium, resulting in chemical corrosion and rust.
3. Cleaning problem: after pickling and passivation, the residual liquid caused by unclean cleaning will directly affect the stainless steel parts.
