Solution to the problem of processing and dyeing aluminum profiles
Sep 03, 2018

In the aluminum profile processing process, it is also necessary to dye according to the production requirements. In the dyeing process, if the thickness of the anodized film is insufficient, the dyeing will not be colored. In view of this situation, it should be checked whether the anodizing process is standardized, and whether the temperature, voltage, conductivity and other factors are stable. If there is any abnormality, please adjust the specification accordingly. If there is no abnormality, the oxidation time can be extended appropriately to ensure the film thickness reaches the standard.

 

In the process of aluminum profile processing and dyeing, if the pH of the dyeing solution is too high or the selected dye is not suitable, it will cause the dyeing to be inconspicuous, or even dyed. Therefore, it is necessary to adjust the pH to a suitable range during the dyeing process. Also, suitable dyeing should be selected for dyeing. In addition, care should be taken to control the placement time of the workpiece in the water tank after oxidation.
