The main reasons why the coated steel plate is not easy to be corroded are as follows:
1. The anti-corrosion performance of the coating layer is good: the coated steel plate is usually coated with a layer of anti-corrosion film on the surface of the steel plate. The film is usually made of polyester, polyvinyl chloride, polypropylene and other materials, which has good barrier and corrosion resistance Performance, can prevent acid, alkali, humid environment and other factors from corroding the steel plate.
2. The coating layer has good sealing performance: the coating layer can be tightly attached to the surface of the steel plate and has good sealing performance, which can prevent the erosion of external moisture, oxygen and chemical substances, and reduce the possibility of corrosion on the steel plate surface.
3. The coating layer is wear-resistant and wear-resistant: steel plates usually face external friction and wear, and the coating layer can provide a protective layer to reduce the wear and tear on the surface of the steel plate, thereby reducing the possibility of corrosion.
4. The coating layer has acid and alkali resistance: the acid and alkali environment is one of the important reasons for steel corrosion, but the coating layer usually has good acid and alkali resistance, and can resist acid and alkali erosion to a certain extent. Protect the surface of the steel plate from corrosion.
It should be noted that although coated steel plates have better anti-corrosion performance than ordinary steel plates, long-term erosion by harsh environments may also cause wear or damage to the coating layer, thereby affecting the anti-corrosion performance of steel plates. Therefore, in the process of using the coated steel plate, we still need to pay attention to regular inspection and maintenance to ensure the integrity and performance of the coated layer.
