Oxidation is a common process used to treat aluminum profiles for solar panel frames. This process involves applying a protective oxide layer on the surface of the aluminum to enhance its durability, corrosion resistance, and aesthetic appeal.
The oxidation process typically involves several steps:
1. Surface preparation: The aluminum profile is cleaned and degreased to remove any dirt, oils, or contaminants that may interfere with the oxidation process.
2. Anodizing: The aluminum profile is immersed in an electrolyte solution and serves as the anode in an electrochemical cell. A direct current is applied, which causes oxygen ions to combine with the aluminum atoms on the surface, forming a layer of aluminum oxide. This oxide layer is integral to the aluminum and provides excellent protection against corrosion.
3. Coloring (optional): If desired, the oxidized aluminum profile can be further treated to add color. This is achieved by immersing the profile in…
