Sulfuric acid anodizing electrolyte method.

Sulfuric acid anodizing electrolyte method
With different concentrations of sulfuric acid to gr/lit10 gr / lit700 industry and research centers anodizing operations, utilized
Said. But most of the concentration typically used is 150 to 250 grams per liter . Concentration in the conduction
The graph below shows the change in electrical communication.
The highest electrical conductivity at a concentration of 350 grams per liter or 35% by weight of sulfuric acid is obtained . In that case,
The voltage needed to create density 1/2 ampere per square decimeter would be the lowest energy
Meanwhile, the electricity is at its lowest .
The relationship between the temperature of the electrolyte solution and the acid concentration of the voltage applied to the density required for half Mprbr square decimeter .
Tested for purity aluminum sheets and also 99/99 percent.
Analysis and experiments indicate that it is appropriate to increase the relative concentration of the electrolyte solution when anodizing operations
Increased thickness and weight, resulting oxide layer is reduced , so that if a piece of aluminum in sulfuric acid solution
Concentration of 30% by weight 330 g body weight anodized oxide layer during a time equal to half of the state
The electrolyte concentration was 15% by weight, or 165 grams per liter Anodizing is at the same time . , One of the research centers in the Middle East in the event that Iran has done a lot of research site , the center is named Mrjh is suitable for use The Institute for Scientific Research, in addition to produce and supply aluminum products Vastyl according to research conducted by its scientists named the Center's website.
