In the production of aluminium alloy is when dyeing, but there will be no color dye, so for this kind of situation, we need to find out what are the causes and solutions, here, you and I together to understand the simple: Harbin Dong Xing Aluminum Co., Ltd is a competent and reliable Aluminum plate  manufacturer china.

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.
4, aluminum alloy plate selected improper dyes: the use of appropriate dyes. Harbin Dong Xing Aluminum Co., Ltd could provide you with 2024 aluminum plate on sale.

5, aluminum alloy plate dye has been decomposed or moldy: at this time need to replace the dye.

6, the low temperature oxidation of aluminum alloy, lead to skin tight: may be appropriate to increase the oxidation temperature.

7, the poor conductivity of copper anode or cathode rod may lead to poor contact in bulk poor conductivity. Pay attention to cleaning the anode and cathode lead copper rod, to ensure good contact.
