How to control the aluminum ion concentration of aluminum insulation jacketing

In anodizing, it is operated according to the normal process conditions, avoiding the high current density and high temperature operation, heat insulation aluminum jacketing, otherwise the aluminum ion may accelerate accumulation.
 

 
In order to avoid the influence of the new anodic oxidation solution on the quality of the film caused by no aluminum ion, it is best to take local replacement when replacing, such as leaving l/3 or 1/4 to make the replacement solution still having a proper concentration of aluminum ions. If the original solution is completely changed because of the pollution, the following method can be adopted. A fixed number of aluminum ions.
 
 
(1) electricity processing. Before the temperature of the newly prepared solution has not been reduced to the working temperature, the discarded aluminum or the waste materials are anodized. At high temperature, the dissolution rate of aluminum is fast, which can meet the requirements of 3 ~ 4H.
 
 
(2) adding aluminum powder. Adding 2 to 3g/L of aluminum powder can also meet the requirements.
