What factors affect the dyeing of aluminum veneer

When dyeing aluminum veneer, what are the specific factors that affect it? As a manufacturer of aluminum veneer in Weifang, let me take you to understand together what factors affect the dyeing of aluminum veneer!

The influence of oxide film on the quality of aluminum veneer. The oxide film refers to the thickness, porosity, transparency, etc. of the aluminum veneer film layer. The thickness of the film layer in aluminum veneer should be kept above um, and the porosity and transparency can achieve good dyeing quality. Dyeing solution temperature. The dyeing of aluminum veneer is divided into cold dyeing and hot dyeing. Cold dyeing is used for a relatively long time in the production process, and the uniformity of the dyed color is easy to control. Hot dyeing has a relatively short usage time, but it is difficult to control the color. The temperature for hot dyeing is usually around ℃.

If the temperature is too high, it will reduce the adsorption of dyeing and easily cause the surface of the aluminum plate to flower. The influence of raw materials on aluminum veneer components. After anodizing, high-purity aluminum, aluminum magnesium, and aluminum manganese alloys in the usual production process have good dyeing functions and can be dyed into various colors. For boards with heavy silicon or copper content, only dark and black colors can be dyed during the dyeing process, which are relatively monotonous colors. Concentration of staining solution.

There is a relationship between the concentration of staining solution and staining. If aluminum veneer is dyed light, the concentration can be lower, and when dyed dark, the concentration can be higher. If the dyeing concentration is relatively high, it will cause uneven color or floating phenomenon, which is prone to "color flow" during the cleaning and closing process In order to enhance the adsorption of dyeing, low concentration colors are used for extended dyeing, which can allow dye molecules to penetrate more evenly into the deep pores of the oxide film, making the dyed color more harmonious and firm.
