anodised aluminium

Anodized aluminum is the sum of chemical reactions of some chemical elements, which is essentially a chemical reaction made by various processes such as coating machine. The specific operation steps are as follows. The main components of color layer: synthetic resin and dye, which have suitable film forming, heat resistance and transparency.

The color layer has two main functions:

1, display color.

2. Protect the aluminized pattern printed on the surface of the article from oxidation. The colors of electrochemical aluminum foil are orange, yellow, gray, red and green. The color of the color layer is given luster after aluminizing, and the color has certain changes, such as yellow is gold after aluminizing and gray is silver after aluminizing. The requirements for color coating are fine, and there should be no small particles, so as to avoid sand holes and destroy the uniformity of coating. Adhesive layer is usually coated with fusible thermoplastic resin (many kinds) on aluminum layer by coating machine, and then dried to form adhesive layer. The main function of the adhesive layer is to adhere the hot stamping material to the object to be ironed.
