60v 500a Anodizing Power Supply
Aluminum anodizing characteristics:
The process of using aluminum or aluminum alloy products as the anode, placing it in an electrolyte solution for energization treatment, and forming an aluminum oxide film on the surface by electrolysis is called anodization of aluminum and aluminum alloys. After anodizing, an aluminum oxide film can be formed on the surface of a few microns—a few hundred microns. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, abrasion resistance and decoration are all significantly improved and improved.
the principle of aluminum anodization is essentially the principle of water electrolysis. When the current passes, the following reactions will occur:
On the cathode, H2 is released according to the following reaction: 2H + + 2e → H2
On the anode, 4OH-4e → 2H2O + O2, the precipitated oxygen is not only molecular oxygen (O2), but also atomic oxygen (O), and ionic oxygen (O-2), usually expressed as molecular oxygen in the reaction .
The aluminum as the anode is oxidized by the oxygen deposited on it to form a anhydrous Al2O3 film: 2AI + 3[O] = AI2O3 + 1675.7KJ It should be pointed out that not all generated oxygen interacts with aluminum, and part of it is precipitated in gaseous form .
Types of anodization Anodization has long been widely used in industry. There are many ways to name different names. There are several classification methods:
According to the current type, there are: direct current anodizing, alternating current anodizing, and shortening the production time to the required thickness. The film layer is thick, uniform and dense, and the pulse current anodizing with significantly improved corrosion resistance.
According to the electrolyte, there are: sulfuric acid, oxalic acid, chromic acid, mixed acid and natural coloring anodizing with organic sulfonic acid solution.
According to the nature of the film layer, there are: anodization of ordinary film, hard film (thick film), porcelain film, bright modification layer, semiconductor barrier layer, etc.
The direct current sulfuric acid anodic oxidation method is most commonly used because it has anodizing treatment suitable for aluminum and most aluminum alloys; the film is thick, hard and wear-resistant, and it can obtain better corrosion resistance after sealing the hole; The film is colorless and transparent, with strong adsorption capacity and easy to color; the processing voltage is low and the power consumption is low; the processing process does not need to change the voltage cycle, which is conducive to continuous production and practical operation automation; sulfuric acid is less harmful to human body than chromic acid and has a wide supply , Low price and other advantages.
In the past decade, my country's construction industry has gradually used aluminum doors and windows and other decorative aluminum materials, and their surface treatment production lines have adopted this method.
