1, means of direct cooling water machine for aluminum oxide, direct cooling tank without cooling pipe is used to avoid anode contacts;

2, greatly increasing cooling efficiency, no need to stir the air pump, reduced operating costs, reliability, strong environmental suitability, and easy maintenance.

3, cold water machine for aluminum oxide applied to zinc plating, tin plating, anodizing, hard anodized, aluminum oxide, acid copper plating, hard chrome plating, is the indispensable partner on the electroplating industry.

[Aluminum oxidation procedures describe]:

1, surface pretreatment by chemical or physical methods to clean the surface, naked pure substrates, in order to obtain a complete and compact artificial oxide film. Can also be obtained by mechanical means specular or Matt (Matt) surface.

2, anodizing: after surface preparation material, under certain conditions, substrate surface Anodic oxidation, forming a dense, porous, strong AL203 membrane adsorption layer.

3, sealing: generated by the Anodic oxidation of porous oxide film membrane pore pore closure, so that the oxide film pollution prevention, enhanced corrosion resistance and wear resistance properties. Oxide film is colorless transparent, use sealing film before strong adsorption, adsorption and deposition of metal salts in the hole, make the profile look to show the true colors (Silver), many of the color, such as: black, bronze, gold and stainless steel and so on.
