characteristics: 

 

   Hard oxidation is called hard anodizing. Hard anodized film generally requires a thickness of 25-150um, most of the hard anodized film has a thickness of 50-80um, and a hard anodized film with a film thickness of less than 25um is used for tooth keys and spirals. For parts, the thickness of the anodized film for wear or insulation is about 50um. Under some special process conditions, it is required to produce a hard anodized film with a thickness of more than 125um, but it must be noted that the thicker the anodized film, the outer The lower the microhardness can be, the roughness of the film surface increases. The hard anodizing bath is generally a sulfuric acid solution and sulfuric acid is added with organic acids, such as oxalic acid and sulfamic acid. In addition, the hard anodizing treatment can be achieved by lowering the anodizing temperature or lowering the sulfuric acid concentration. For deformed aluminum alloys with a copper content greater than 5% or silicon content greater than 8%, or high-silicon die-cast aluminum alloys, special measures for anodizing may also be considered. For example: For the 2XXX series aluminum alloy, in order to avoid the aluminum alloy from being burnt during the anodizing process, 385g/L sulfuric acid plus 15g/L oxalic acid can be used as the electrolytic bath liquid, and the current density should also be increased to more than 2.5A/dm .

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.

 

Switching type rectifier
Voltage and Current Control
Up to 50% energy saving
30% less anodizing time for same thickness of oxidation

Increase temperature of anodizing solution due to the reduction of oxidation voltage
Reduced barrier-layer
Pulses help avoid burned parts at high current density Same rectifier can be used for anodizing and coloring Due to reverse polarity, anodizing for special aluminium alloys (copper, silica, etc.) is easier

Multitower expansion for higher current requirement Different programmable waveform for different process application. Manual or PC/PLC control

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.
