The surface of the industrial aluminum profiles
we see in the industrial field or in life is smooth and flat, very bright, easy to clean, and corrosion-resistant. These are all because the surface treatment of the industrial aluminum profile profile is carried out after being extruded, which is what we commonly call the coloring of the industrial aluminum profile. Those who are familiar with aluminum profiles know that there are three steps for coloring aluminum profiles. Let's take the specific three steps together: 1. Surface pretreatment. The surface pretreatment of industrial aluminum profile profiles means cleaning the surface of aluminum profiles by chemical or physical methods. , Can show the original color of aluminum, we can also obtain mirror or matte aluminum surface through mechanical means. 2. Surface anodic oxidation of industrial aluminum profiles
After surface treatment, under certain processing conditions, anodize the surface of the aluminum profiles, and the oxidized aluminum surface will form a porous and strong adsorption protective film. 3. Sealing is to close the pores of the porous oxide film produced by the industrial aluminum profile after anodization to improve the corrosion resistance of the aluminum material. We can use the strong adsorption of the oxide film before sealing to prevent the pores of the film. Some metal salts are adsorbed and deposited inside, so that the aluminum profile shows a color other than the natural color. There are many processing methods for industrial aluminum profile profiles after extrusion, and the three steps of surface treatment are like this. If you need to assemble it into an aluminum profile rack or other frame, you need to cut, punch or tap the aluminum profile.
