Lightweight casement window architectural aluminum profile

What surface treatments are usually required for lightweight casement window architectural aluminum profiles? Such as anodizing, electrophoresis, porcelain coating or fluorocarbon spraying, etc. What impact do these treatments have on the corrosion resistance, wear resistance and aesthetics of aluminum?

The surface treatment of lightweight casement window architectural aluminum profiles mainly includes several mainstream technologies such as anodizing, electrophoretic coating, porcelain coating and fluorocarbon spraying. Each process has its unique advantages and applicable scenarios, which can significantly improve the overall performance of aluminum materials.
1. Anodizing
Anodizing is a treatment technology that uses electrochemical methods to form a dense aluminum oxide film on the surface of aluminum materials. This oxide film has high hardness, good wear resistance, and good corrosion resistance and insulation. The surface of anodized aluminum exhibits the natural luster of metal and has a delicate texture. It can effectively resist ultraviolet erosion, prevent oxidation and fading, and maintain long-term bright colors.
2. Electrophoretic coating
Electrophoretic coating is a method that uses the action of an electric field to directionally migrate charged paint particles to the surface of aluminum materials and deposit them to form a coating film. This process can give aluminum materials a rich range of color options, while the coating film is uniform, strong adhesion, and has excellent corrosion resistance, weather resistance, and wear resistance. Electrophoretic coating can also effectively isolate the aluminum material from direct contact with the external environment, further extending the service life of the product.
3. Porcelain swimming
Porcelain coating is a new type of aluminum surface treatment process. Its principle is similar to electrophoretic coating, but the coating used is porcelain coating. The surface of the aluminum material after porcelain bathing treatment presents a texture similar to ceramics, with high gloss, delicate touch, and excellent weather resistance, corrosion resistance and wear resistance. In addition, the porcelain swimming process can effectively reduce fingerprint residue and keep the aluminum surface clean and beautiful.
4. Fluorocarbon spraying
Fluorocarbon spraying is a spraying technology that uses fluorocarbon resin as the main film-forming substance. Fluorocarbon coatings have extremely high weather resistance, corrosion resistance and chemical resistance, and can maintain the integrity and beauty of aluminum surfaces in extremely harsh environments. At the same time, fluorocarbon spraying can also give aluminum materials rich colors and textures to meet the diverse needs of architectural design.
Effect of treatment process on aluminum properties
1. Corrosion resistance
The above four surface treatment processes can all form a dense protective film on the surface of the aluminum material, effectively isolating the direct contact between the aluminum material and the external environment, thereby significantly improving the corrosion resistance of the aluminum material. Among them, the oxide film and coating film formed by anodizing and electrophoretic coating have excellent chemical stability and can resist the erosion of various corrosive media; porcelain coating and fluorocarbon spraying further improve their performance through their unique coating composition and process characteristics. Enhanced corrosion resistance of aluminum.
2. Wear resistance
The aluminum oxide film formed by anodizing has high hardness and good wear resistance, and can effectively resist scratches and wear; the coating film formed by electrophoretic coating and porcelain coating also has excellent wear resistance and can keep the aluminum surface smooth and smooth. Smooth; fluorocarbon spraying further improves the wear resistance of aluminum through its high-hardness coating.
3. Aesthetics
Surface treatment technology not only improves the performance of aluminum, but also gives it rich colors and textures. Anodizing retains the natural metallic luster of aluminum, electrophoretic coating and porcelain coating provide a variety of color choices, and fluorocarbon spraying can simulate various natural textures such as imitation wood grain and imitation stone to meet the diverse needs of architectural designs. needs.
