Reason:

1. The stainless steel mesh in the polluted air (such as atmosphere containing a large number of sulfides, carbon monoxide, nitric oxide), encounter condensate, form sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.
2. The stainless steel mesh surface contains acid, alkali and salt substances (such as alkaline water and lime water splashing on the wall decoration), causing local corrosion.
3. The surface of stainless steel mesh is deposited with dust containing other metal elements or the attachment of heterogeneous metal particles. In humid air, the attachment and the condensate between stainless steel are connected into a micro-battery, which triggers the electrochemical reaction and damages the protective film. It is called electrochemical corrosion.
4. The surface of stainless steel mesh is adhered with organic juice (such as melon, vegetable, noodle soup, phlegm, etc.), which forms organic acid in the presence of water and oxygen, and corrodes the metal surface for a long time.
Resolvent:
1. The surface of decorative stainless steel mesh must be cleaned and scrubbed regularly to remove the attachments and eliminate the external factors that cause the modification.
2. Some stainless steel mesh chemical composition on the market can not meet the corresponding national standards, can not meet the material requirements of 304. Therefore, it will also cause rust. This requires users to choose products of reputable manufacturers seriously.
