Under What Circumstances Is The Stainless Steel Filter Cartridge Easy To Rust?

Stainless steel filter cartridge is not easy to rust by name, but it will rust sometimes. In which cases is it easy to rust under the stainless steel filter cartridge?

When the stainless steel filter screen cylinder is in polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), it meets with condensate to form sulfuric acid, nitric acid and acetic acid liquid points, causing chemical corrosion.

The surface of stainless steel filter screen cylinder contains acid, alkali and salt substances (such as alkali water and lime water splashing on the decoration wall), causing local corrosion.

The surface of stainless steel filter screen cylinder adheres to organic juice (such as melons and vegetables, noodle soup, phlegm, etc.), which forms organic acid under the condition of water and oxygen. For a long time, the corrosion of organic acid on the metal surface will be reduced.

There are dust containing other metal elements or attachments of dissimilar metal particles on the surface of the stainless steel filter tube. In the humid air, the condensate between the attachments and the stainless steel connects them into a micro battery, which leads to electrochemical reaction and damage to the protective film, which is called electrochemical corrosion.
