Aluminum profiles are more common. In use, there are many ways to solve the surface of aluminum profiles, and coloring is one of them. So how to color aluminum profiles?

In fact, the aluminum profile before coloring, need to carry out oxidation of the aluminum profile, extrusion good 8080 industrial aluminum profile, its surface corrosion resistance is not strong, according to the anodic oxidation to carry out the surface solution to improve the leveling of aluminum, wear resistance and surface beauty.

The whole process of aluminum coloring is:

(1) surface preparation treatment: clean the surface of the aluminum profile by chemical or physical means, and expose the pure base material by anodic oxidation of aluminum, in order to get detailed and high density human oxide film. It can also obtain mirror glass or no light (matte) surface according to mechanical equipment.

(2) Anodic oxidation: after surface preparation treatment of aluminum profile, under a certain technical standard, the substrate surface anodic oxidation, into a layer of high density, porous structure and strong adsorption AL203 film layer.

(3) Hole sealing: the porosity of the porous structure of the oxide film formed after anodic oxidation is closed, so as to improve the pollution treatment, leveling and wear resistance of the oxide film. The oxide film is colorless and transparent, using the strong adsorption force of the oxide film before sealing the hole, in the membrane hole absorption of some metal salt, can make the material surface present a lot of colors other than the primary color (silver), such as: gray black, copper, orange yellow and stainless steel plate color. Customers ask you for engineering drawings, not physical objects. If it is an engineering drawing, according to the engineering drawings, calculate the volume of aluminum, formula calculation is: long (cm)* wide (cm)* high (cm), figure out the volume of aluminum is N cubic, and then multiplied by the relative density of aluminum :2.7 grams/cubic. The result is the net weight of aluminum.
