Purification board is a composite board made of colored coated board and other materials. It has good anti-static effect. Widely used in industries such as electronics, pharmaceuticals, aerospace, etc. Under normal usage conditions, the board will not rust, and if damaged by external forces, it may also rust.
The reason is that the purification board contains iron, and due to long-term wind and rain, the surface coating will inevitably be damaged. Once damaged and in contact with acids, alkalis, and organic solvents, a chemical reaction occurs, forming iron oxide, known as rust. When corrosion is severe, holes will appear.
The second reason is that it often rains and can rust after prolonged use. Once it rains, the rust on the roof will be affected by the environment and the oxidation and decomposition of acid and alkali rainwater. The rainwater flows along the wooden boards, creating corrosion marks. After a long period of time, there will be extensive corrosion on the roof.
The third reason is that during the construction process, due to the carelessness of the construction personnel, the surface coating may be damaged, which may also lead to rust on the purification board. Therefore, during the construction process, construction personnel should pay attention to the construction and be careful not to damage the surface coating.
