      If the color effect of aluminum plate can not achieve the ideal effect, its application will have a great impact. So, what are the specific factors of color difference on the surface of aluminum plate in production? Mainly in the following aspects:
      1. Temperature of dye solution
      Aluminum plate dyeing is divided into cold dyeing and hot dyeing. Cold dyeing is used for a long time in the production process and has a good grasp of color uniformity. The use of heat dyeing is short-lived, but it is difficult to manipulate the color. The thermal dyeing temperature is generally 40 ° C ~ 60 ° C. if the temperature is too high, it will reduce the adsorption of dyeing and make the surface of aluminum plate easy to blossom.

      2. Thickness of aluminum oxide film
      Oxide film refers to the thickness, porosity and transparency of aluminum plate. The thickness of aluminum plate oxide film can be maintained above 10 microns to obtain porosity and transparency and better dyeing quality.
      3. Concentration of dye solution
      The relationship between the concentration of the dyeing solution and the dyeing. Colored aluminum plate, lower concentration, dark slightly higher concentration. If the higher concentration of dye will be uneven or floating color, it will easily occur in the washing process and in the closed "color flow". In order to improve the dye adsorption capacity of dyes, when dyeing with low concentration of color, dye molecules penetrate into the hole depth of more uniform oxide film and make the color more harmonious solid.
      4. Affecting the raw materials of aluminum plate
      Generally, high purity aluminum, aluminum magnesium and aluminum manganese alloys have good dyeing performance and can be dyed into a variety of colors after anodizing in the production process. For heavy silicon or copper plate, they can only be dyed dark and black in the dyeing process, and the color is monotonous.
