How does the aluminum plate factory solve the dyeing problem of patterned aluminum plates? Patterned aluminum plates are widely favored by citizens due to their excellent characteristics such as decoration, durability, etc. However, there are some dyeing problems in the production process of patterned aluminum plates that cannot meet the expected results of the manufacturer. To solve this problem, the aluminum plate factory shares four methods to solve the dyeing problem of patterned aluminum plates.
Choose the right raw materials for aluminum plate parts: usually, high-purity aluminum aluminum magnesium aluminum manganese alloy in the production process is anodized, and its dyeing function is good, which 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.
Control the thickness of the oxide film: The oxide film refers to the thickness, porosity, transparency, etc. of the aluminum plate film layer. The thickness of the film layer in the aluminum plate should be maintained above 10um, and the porosity and transparency can achieve good dyeing quality.
Grasp the concentration of the dyeing solution: There is a connection between the concentration of aluminum plate and dyeing. If the aluminum plate is dyed light, the concentration can be lower, and if dyed dark, the concentration can be higher. The color of the aluminum plate material that is usually dyed lighter is 0. 1-0. 39g/L, light color is 1g/L, deep color is 3-5g/L, and dense color is 10-15g/L. If the dyeing concentration is relatively high, it will cause uneven color or floating color phenomenon, which is easy to occur 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.
Control the temperature of the dyeing solution: The dyeing of aluminum plates is divided into cold dyeing and hot dyeing. Cold dyeing is used for a relatively long time during the production process, and the uniformity of the dyed color is easy to control. The use time of hot dyeing is relatively short, but it is difficult to control the color. The temperature of hot dyeing is usually between 40-60 ℃. If the temperature is too high, it will reduce the adsorption of dyeing and easily cause the surface of the aluminum plate to flower.
