In order to meet the needs of users, decorative aluminum coils are generally surface treated before they can be put on the market, so the surface treatment of decorative aluminum coils is more important.
There are currently no more than three surface protection methods for decorative aluminum coils:
(1) Anodizing, aluminum alloy doors and windows have been introduced in the 1950s, and it is still a commonly used surface treatment measure for aluminum doors and windows and decorative aluminum panels;
(2) Electrophoretic acrylic resin after anodic oxidation, which was commercialized in Japan in the 1960s, and used in Europe in the 1970s, and is currently mainly used in Asia. The technology has been developed from transparent bright film to matt transparent film and color film, the varieties are more diversified, and the industrial control and product quality are relatively stable;
(3) Electrostatic spraying after chemical conversion treatment includes electrostatic powder spraying and electrostatic liquid-phase spraying. Electrostatic liquid-phase spraying fluorocarbon resin has been commercialized in the United States in the 1960s. The electrostatic powder spray thermosetting polyester coating has been commercialized in Europe in the late 1960s, and is still the dominant surface treatment method in European countries. Today, single-anodized aluminum doors and windows are significantly shrinking in domestic and foreign markets. Japan favors electrophoretic coatings. White electrophoretic coatings have developed rapidly and have been applied in Europe. Electrostatic powder spraying has become the preferred surface treatment method in Europe and the United States due to its diverse colors, convenient control, environmental protection, and excellent performance. In recent years, the electrostatic powder coating market is also rapidly expanding in my country.
(4) Spray painting: It is usually fluorocarbon spraying. The treatment of aluminum coil before painting is more important. Passivation treatment is required to ensure that the paint and aluminum coil are closely combined. The typical application is that the curtain wall aluminum coil adopts this method for surface treatment.
