(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 ...

The high-frequency welded finned tube is a disadvantage of a heat sink made of a string type and a wound fin, and an improved heat-dissipating element using a high-frequency welded finned tube is improved, and the finned tube itself has a thickness of 0.8. -1mm strip is wound on the finned tube, and the high-frequency welding process is used to weld the sheet to the tube to ensure the bonding strength between the tube and the fin. The metal thermal strength has reached 1.10~1.20w/kg°C. The finned tube is widely used in the economizer of the boiler, the production and workshop of the air preheater, the production of the energy-saving radiator of the house, and the first choice for the heat treatment of the heat pipe. The spiral finned tube is a highly efficient heat transfer element. Its he...
