What are the regular colors of aluminum profiles?
The main process is:(1) surface pretreatment: chemical or physical methods are used to clean the surface of the profile and expose the pure matrix to obtain a complete and compact artificial oxide film. The mirror or non light (Ya Guang) surface can also be obtained by mechanical means.(2) anodizing: the surface of the pre processed profiles, in a certain process conditions, the substrate surface anodic oxidation, resulting in a dense, porous, strong adsorption of AL203 film.(3) sealing: the pore space of the porous oxide film produced by anodic oxidation is closed, so that the oxidation film is anti pollution, and the corrosion resistance and wear resistance are enhanced. The film is colorless and transparent, with strong adsorption before sealing film, adsorption and deposition of metal salts in some membrane hole, can make the profile appearance character (silver) show many colors, except such as: black, bronze, golden color and stainless steel etc..
White is the normal color! Whether semifinished material or oxidation material! Blank just squeeze out the true color of stone aluminum! Silvery white！ Exposure to air for a long time! Occurs naturally oxidizes, can blacken! So we have to do artificial oxidation! The conventional artificial oxidation is white! So there is no special color silver oxide oxidation collectively required! !!!
The regular colors of aluminum profiles of different treatment processes are as follows:Electrophoresis: Champagne, silver, bronze, stainless steel color, golden yellow, blackOxidation: Champagne, silver, bronze, stainless steel color, golden yellow, blackSpraying: any colorAluminum in the paint before the first oxidation of aluminum extrusion profiles, Aluminum Alloy good corrosion resistance, the surface is not strong, should be to increase the aluminum corrosion resistance, wear resistance and surface by anodic oxidation surface treatment of the appearance of the.
