What are the reasons for the rust of the stainless steel filter?

Ordinary stainless steel filter mesh has the ability to resist atmospheric oxidation-that is, rust resistance, and also has the ability to resist corrosion in media containing acid, alkali and salt-that is corrosion resistance. However, its anti-corrosion ability varies with its brand and environment. For example, 304 stainless steel filter mesh has absolutely excellent anti-corrosion ability in a dry and clean atmosphere. However, if it is moved to a coastal area, it will contain a lot of salt. In the sea fog, it will rust soon; while the 316 stainless steel filter of MAISHI GROUP performs well. If the stainless steel filter is rusty, it can be treated with plastic or replaced with a new and better material MAISHI stainless steel mesh.

Common causes of stainless steel filter rust:

1. The surface of stainless steel has accumulated dust containing other metal elements or attachments of foreign metal particles. In humid air, the condensation between the attachments and stainless steel connects the two into a micro battery, which initiates an electrochemical reaction. , The protective film is damaged, which is called electrochemical corrosion.

2. The surface of the stainless steel mesh adheres to the organic juice (such as melon, vegetable, noodle soup, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.

3. The surface of stainless steel mesh adheres to containing acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.

4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots when encountering condensed water, causing chemical corrosion.

MAISHI GROUP mainly produces stainless steel filter mesh, including different models such as 304 stainless steel, 316 stainless steel, 316L stainless steel, and so on. If you have any needs, please feel free to contact us.
