What is the coloring process of industrial aluminum?

Aging and heat preservation after extrusion of industrial aluminum profiles: Aging should be carried out in strict accordance with the process requirements, and the heat preservation time should be appropriate to prevent under-ageing or over-ageing from causing insufficient hardness. The blanks are framed and furnaced. After the surface of the industrial aluminum profile profile is oxidized, it looks very beautiful and resistant to dirt. Once it is coated with oil, it is easy to clean. When assembled into a product, different specifications of profiles are used according to different load-bearing materials, and matching aluminum profile accessories are used, without welding. It is more environmentally friendly, and it is light and easy to carry and easy to move and install and disassemble. Before the aluminum profile is loaded into the furnace, the other special alloys of 6x and the ordinary 6063 alloy shall be loaded separately for aging. When the aging is done in the same furnace due to production reasons, the special alloy process shall be used for aging. After the aluminum profile is extruded, the frame of the aluminum profile should not be too dense, and there must be a gap between the materials. The gap between the aluminum profile, especially the small and thick materials without ventilation, is even larger. The pipe material is combined with the small material and the sheet material. When a frame is installed, the pipe material is placed below, which is conducive to the aging cycle air supply. profile extrusion: Extrusion is a means of profile forming. First, make a mold according to the aluminum profile product drawing, and use an extruder to extrude the heated round cast rod from the mold. Coloring of industrial aluminum profile profiles (the process of oxidation is mainly discussed here) Oxidation: The surface of the extruded aluminum alloy profile is not strong in corrosion resistance, and it must be surface treated by anodizing to increase the corrosion resistance and resistance of the aluminum material. Abrasiveness and aesthetics of appearance. The main process is: Surface pretreatment: clean the surface of industrial aluminum profile profiles by chemical or physical methods, and expose the pure matrix, in order to obtain a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte (matt) surface by mechanical means. ————The article comes from the Internet. If there is any infringement, please contact to delete it.
