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.

How to install rectifier
This is installation way for remote control rectifier. Not only
this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power
supply/rectifier
4. We advice that all rectifiers should be isolated to increase of
its life.
