Cum este imprimat aluminiu colorat?

1. Alegeți placa de aluminiu potrivită - în procesul de producţie, oxidarea anodică a plăcilor de aluminiu pur, placa de aluminiu magneziu aluminiu și placa de aluminiu mangan aluminiu efectul de colorare este mai bun. Pentru plăci de aluminiu cu conținut ridicat de siliciu sau cupru, only dark and black color can be dyed during the dyeing process.

2. Control oxide film thickness - Filmul de oxid se referă la grosime, porosity and transparency of aluminum film. The thickness of the film in the aluminum plate should be kept above 10um to obtain good dyeing effect.

3. Pay attention to the dye concentration - the dye concentration has a certain relationship with the dyeing effect. If the aluminum plate is light colored, the concentration can be lower, otherwise it can be higher. In order to enhance the absorption of the stain, a low concentration of color will be used for further staining, so that the dye molecules more evenly penetrate into the pores of the oxide film, so that the color of the stain is more harmonious and firm.

4. Pay attention to the temperature of dye solution - aluminum dyeing is divided into cold dyeing and hot dyeing. Cold dyeing takes a long time to achieve the desired results, and the uniformity of color is relatively easy to master. The hot dyeing time is short and the color is difficult to control.
