Plate pattern aluminum plate for its decorative, durability and other excellent characteristics, widely accepted by the public pro-endurance, but in the production process there are some pattern aluminum plate staining problems, can not achieve the desired effect of the producer, in order to deal with this problem, we share four ways to deal with the staining problem of pattern aluminum plate.
First, select a good aluminum plate material. General production process of high purity aluminum, aluminum magnesium, aluminum manganese alloy through anodic oxidation in the future, its dyeing function is the best, can be dyed into a variety of colors. About the silicon or copper-containing heavy plate, in the dyeing process can only be dyed into dark and black, monotonous color.
Second, control the thickness of the oxide film. Oxide film is the thickness, porosity, transparency, etc. of the membrane layer of aluminum plate. Aluminum plate in the thickness of the film layer to maintain more than 10um will be able to, porosity and transparency, can get the best dyeing quality.
Third, master the concentration of the dyeing solution. Aluminum plate concentration and dyeing has a link between, if the aluminum plate dyeing light color, the concentration can be a little lower, dyeing dark color concentration can be a little higher. The general production of aluminum plate material dyed light color color 0.1-0.39g / L, dyeing light color 1g / L, dyeing deep color 3-5g / L, dyeing dense color 10-15g / L, if the dyeing of the concentration is high will cause uneven color or floating color phenomenon, in the process of cleaning and closed easily present "flow color In the process of cleaning and sealing, it is easy to show "flowing color". In order to strengthen the adsorption of dyeing, the use of low concentration of color to extend the dyeing, so that the dye molecules penetrate into the depths of the pores of the oxide film more uniformly, which can make the dyeing of the color more harmonious and solid.
Fourth, control the temperature of the dyeing solution. Aluminum plate dyeing is divided into cold dyeing and hot dyeing. The use of cold dyeing, in the production process, the use of a longer period of time, the dyeing of color uniformity is better to master. Hot dyeing is used for a shorter period of time, but it is more difficult to control the color. The temperature of hot dyeing is generally 40-60℃. If the temperature is too high, it will reduce the adsorption of dyeing, and it is easy to cause the appearance of the aluminum plate to blossom.
