Anodizing of aluminum profiles can be used in daily life. Due to the characteristics of this process, a hard protective layer is formed on the aluminum surface, which can be used to produce daily necessities such as kitchen supplies. However, the anodizing effect of cast aluminum is not very good, and the surface is uneven and only black and gray. Aluminum profiles are stronger. The following is a brief introduction to the aluminum sheet oxidation solution.
How to deal with oxidation of aluminum sheets
In the past ten years, aluminum oxidation and coloring technology has made rapid progress in my country. Many factories have adopted new process technologies and accumulated sufficient experience in actual manufacturing. The anodizing process of aluminum and aluminum alloys has been perfected and developed, and the appropriate process can be selected according to specific manufacturing needs. Before choosing the oxidation process, we need to understand the raw materials of aluminum or aluminum alloy profiles. Because the difference in raw material quality and composition will directly affect the quality of aluminum products after anodization.
For example, if the aluminum surface has defects such as bubbles, scratches, peeling, and roughness, most defects will still occur after anodization. The alloy composition also affects the surface appearance after anodization.
For example, aluminum alloy profiles containing 1 to 2% manganese turn brown to dark blue after oxidation, and the surface color after oxidation changes from brown to dark blue to dark brown.
Aluminum alloy profiles containing 0.6 to 1.5% silicon turn dark gray after oxidation, while those containing 3 to 6% silicon turn white gray.
It shows milky color when containing iron, orange to dark gray when containing magnesium, and light yellow when containing nickel.
Generally speaking, only aluminum containing more than 5% magnesium and titanium can obtain a colorless, transparent, bright and clean appearance after oxidation.
After selecting aluminum and aluminum alloy materials from aluminum sheet manufacturers, of course you must consider choosing the appropriate anodizing process. At present, hydrochloric acid oxidation, oxalic acid oxidation and chromic acid oxidation are widely used in us.
