1, aluminum alloy aluminum alloy anodic oxide film thickness problem: the solution is to check whether the anodizing process specification, temperature, voltage, or conductive factors such as stability, if abnormal, please adjust the specification, without exception, may be appropriate to extend the oxidation time, ensure the film thickness standard.

2, aluminium alloy when pH value is too high: at this point, can be used acetic acid to adjust the pH value to the standard value.

3, aluminium alloy after oxidation of the workpiece in the tank placed too long: the promotion of timely staining, if this situation has occurred, the workpieces can be put in proper activation treatment of anodic oxidation tank or nitrate neutralizing bath after dyeing, the effect will be very good.
