Colored stainless steel decorative plates in corrosive environment

The application fields of colored stainless steel plates are very wide, so how to maintain stainless steel plates to make them more durable? Today I will let you know about the circumstances under which colored stainless steel plates are easily corroded.

1. Dust containing other metal elements or attachments of heterogeneous metal particles accumulate on the surface of the stainless steel plate. In humid air, the attachments and the condensed water between the colored stainless steel plates connect the two into a micro-battery, causing Electrochemical reaction destroys the protective film, which is electrochemical corrosion.

2. Organic juice (such as vegetables, noodle soup, phlegm, etc.) adheres to the surface of the stainless steel plate. In the presence of water and oxygen, it forms organic acid. For a long time, the organic acid corrodes the metal surface.

3. The surface of the stainless steel plate contains acid, alkali, and salt substances (such as alkaline water and lime water splash on the wall decoration), causing local corrosion.

4. In polluted air (such as an atmosphere containing a large amount of sulfides, carbon oxides, and nitrogen oxides), when encountering condensed water, sulfuric acid, nitric acid, and acetic acid liquid points will form, causing chemical corrosion.

Many people have a misunderstanding that colored stainless steel plates are more durable than iron plates, so they do not pay much attention to the maintenance of colored stainless steel plates. In fact, whether it is stainless steel or other more advanced materials, there will always be its nemesis, but it is not common. Therefore, in order to make the colored stainless steel plate durable, everyone still needs to pay attention to the above 4 points.
