(3) Tinted

The aluminum alloy prototype tinted method include : Electrochemical tinted, chemical staining and natural coloration (overall staining) three kinds of type, In aluminum alloy prototype electrolytic tinted process, the electrochemical reduction of metal (oxide) may also be generated particles deposited at the bottom of the oxide film microporous,  The color is not the color of the sediments, It's the scattering of light from the deposited particles. Chemical dyeing are inorganic or organic dye adsorption at the top of the oxide film microporous,  The color is the color of the dye itself.  Electrolytic tinted not only in low cost, but also has good weather resistance and other performance. Chemical staining is very colorful, but it is easy to change color when used outdoors.

The aluminium product  and aluminium alloy of chemical oxidation processing equipment have the following characteristics:  easy operation, high production efficiency,  save electricity, wide range of suitability ,There is no limited on size and shape of the parts etc. Oxide film thickness of about 5 ~ 20 microns (hard anodic oxidation film thickness up to 60 ~ 200 microns), has high hardness, good heat resistance and insulation, The corrosion resistant ability higher than that of chemical oxidation film, porous that has good adsorption capacity.
