Aluminum coil is one of our products. As a manufacturer with many years of production experience, we have a deep understanding of aluminum coil. Today, I'd like to introduce the specific coloring steps of aluminum coil:
We will do pre-treatment, first use methods to clean the surface, cleaning methods include physical methods and chemical methods, mainly exposed aluminum roller matrix. This is conducive to complete oxidation, and the oxide film formed will be relatively compact. Pretreatment can also be done with some mechanical equipment. After anodizing, the base material of the aluminum coil will undergo anodizing reaction, and then a layer of dense oxide film will be produced to protect the aluminum coil.
The above is the relevant content introduced by the aluminum plate manufacturer for you. To learn more, please visit the website: http://www.jndclyxgs.com
