Color Stainless Steel Decorative Plate | Corrosive Environment

The application field of colored stainless steel plate is very wide, so how to maintain the stainless steel plate to make it more durable? Today, I will take you to understand under what circumstances the colored stainless steel plate is easy to be corroded.

1. On the surface of the stainless steel plate, there are deposits of dust or heterogeneous metal particles containing other metal elements. In the humid air, the condensed water between the deposits and the colored stainless steel plate connects the two into a micro-battery, causing a Electrochemical reaction, the protective film is destroyed, which is electrochemical corrosion.

2. Organic juices (such as vegetables, noodle soup, sputum, etc.) adhere to the surface of the stainless steel plate. In the presence of water and oxygen, organic acids are formed, and organic acids will corrode the metal surface for a long time.

3. The surface of the stainless steel plate adheres to substances containing acids, alkalis and salts (such as alkali water and lime water splashing from the decoration walls), causing local corrosion.

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

The misunderstanding of many people is that colored stainless steel plates are more durable than iron plates, so they are not very concerned about 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, so in order to make the color stainless steel durable, you still need to pay attention to the above 4 points.
