Whether it is aluminum or aluminum alloy, a very important process is the surface treatment. Today, I will introduce the treatment process of the current mainstream aluminum plate surface.   One: Electrophoretic painting. After such treatment, the surface of the material exhibits a smooth side and the corrosion resistance is greatly enhanced. Two: powder electrostatic spraying. This process is characterized by enhanced corrosion resistance of aluminum sheets, and for some acid-base salts, the use of aluminum sheets is superior to oxidized colored profiles.   Three: multi-tone surface treatment. Nowadays, in order to make the aluminum plate work better together, various color treatments have naturally appeared, so that the color of the aluminum plate can be further improved. The last one is...

(3) Electrostatic spraying after chemical conversion treatment includes electrostatic powder spraying and electrostatic liquid phase spraying, and electrostatic liquid phase spraying of fluorocarbon resin has been commercialized in the United States in the 1960s. The electrostatic powder coating of thermosetting polyester coatings has been commercialized in Europe in the late 1960s and is still the dominant surface treatment in Europe. Today, single anodized aluminum doors and windows are significantly reduced in Japan and abroad, and Japan prefers electrophoretic coatings. White electrophoretic coatings have developed rapidly and are used in Europe. Electrostatic powder coating has become the preferred surface treatment method in Europe and America for its various colors, convenient contr...

In order to meet the needs of users, decorative aluminum panels are generally surface treated to be put on the market, so the surface treatment of decorative aluminum panels is more important. How to install decorative aluminum panels, how to protect the surface of decorative aluminum panels? The following is a brief description of the surface treatment methods of decorative aluminum panels. Surface protection method for decorative aluminum panels: (1) Anodizing, aluminum alloy doors and windows have been introduced in the 1950s, and it is still the usual surface treatment measures for aluminum doors and windows and decorative aluminum panels; (2) Electrophoretic acrylic resin after anodization, which was commercialized in Japan in the 1960s, and used in Europe in the 1970s, and is current...

Aluminum sheet products are widely used in the automotive, construction and other industries. Improving the quality of aluminum products is the foundation of the company's survival. Aluminum materials are extremely unstable in the air, and it is easy to produce oxide films that are difficult to identify with the naked eye. Due to the different processing methods of aluminum parts, such as casting molding, or directly cutting from the rolled sheet, or mechanical fine processing, or after different processes, heat treatment or welding, the surface of the workpiece will be presented. Different states, different degrees of dirt or traces, for this reason, in the pre-treatment process, the pre-treatment process must be selected according to the actual situation of the workpiece surface.  It is ...
