The original aluminum is silver, but now the market has black, yellow and green, aluminum radiator, radiator is the color what are formed by oxidation of different colors, what are the benefits of it, are used in the above types of products?
In this process, there is no difference for several different color film properties, the only difference is that the surface of different colors can increase the appearance of the product, can choose different colors according to the requirements of different products.
Generally speaking, there are 2 kinds of processes for the surface treatment of aluminum profiles, which are hard anodizing coloring and color coating. Among them, hard anodic oxidation dyeing is more common.The basic process of the hard anodic oxidation dyeing is the use of additives mixed with sulfuric or chromic anodic oxidation treatment of aluminum, an aluminum oxide film layer generates high hardness aluminum surface treatment, because the alumina itself has no color and with a lot of space, so the oxygen after the general meeting of the colorant and sealing agent for the further treatment, protective properties of the oxide film has been further improved after treatment, but also can make the aluminum surface with different colors.
As for the coating and metal coating materials processing as the first surface degreasing and coarsening process, then spraying or cathodic electrophoresis mode is used in aluminum surface with a layer of film, choose different properties and color of paint can make the aluminum surface to obtain the corresponding protection performance.
