The role of purification in the production process of aluminum profiles mainly includes the following points:

Remove the internal oxide and metal ions: electrolytic purification can remove the oxide and metal ions inside the aluminum profile, improve the resistivity and electrical conductivity of the aluminum profile

Improve surface finish and corrosion resistance: aluminum profiles can remove impurities such as dirt and oxide on the surface through electrolytic purification treatment, improve the surface finish and corrosion resistance of aluminum profiles, and make the products more beautiful and durable

Enhance the corrosion resistance of aluminum profiles: The purified aluminum profiles have better corrosion resistance in various harsh environments, such as high temperature, humidity, acid and alkali, and extend the use

Improve the surface quality of aluminum profiles: Purifying aluminum profiles can remove surface dirt and oxides, improve the surface quality of aluminum profiles, and reduce the rate of unqualified products

Enhance decorative performance and texture: The purified aluminum profile surface is smoother and more uniform, which not only improves the decorative performance of the product, but also enhances its texture and sense of quality

Conducive to subsequent surface treatment: the purified aluminum alloy material is more conducive to subsequent surface spraying, electroplating, anodizing and other treatments
