Painting technology of steel for appliances
Introduction of the feature
1. Improve the service life of steel parts in home appliances
All steel parts will rust and rot in the air through contact and penetration with corrosive media (O2, H2O, CI, etc. in the air) until they lose their original mechanical strength. In order to delay the occurrence of rust, the most commonly used means It is to apply an organic coating on the surface of steel parts to isolate the steel parts from corrosive media and play a physical protection role.
2. Decorative
Through the application of organic coatings, the cold and monotonous appearance of steel plates can be completely changed. Organic coatings can give steel plates various colors and textures to meet aesthetic requirements.
