Aluminum oxide is a chemical reaction of some chemical elements, in essence, a chemical reaction is made by coating machine and other processes, and the specific operation steps are as follows.
16um thick biaxially stretched polyester film is generally used in the folding substrate layer, which is mainly used to support the continuous action of the coating attached to it and to facilitate the hot stamping process. It shows that the base film can not be deformed by rising temperature during hot stamping, and it should have high strength, tensile resistance, high temperature resistance and so on.
The detachment layer is mainly coated with organic silicone resin. The main component of the second layer off layer in the electrochemical aluminum foil is organic silicone resin. Its main function is that after hot stamping, whether it is heated or pressurized, it will make the color material, aluminum, rubber layer, The film can be rapidly detached and transferred to the surface of the hot stamping object, indicating that there is a process in the aluminum and composition is to separate the layer, and in the layer containing a chemical (organic silicone resin). The main purpose is to help the material transfer very well, and the main function of our finished bronzing materials is to put all kinds of bronzing materials on them or to press them on them, so as to achieve the effect of printing them on them. The main component in the substrate layer is (polyester film). It is mainly to prevent the process of hot stamping stretch and change, so that the stamping process is perfect. There is no change in temperature at all. And strong, high temperature, tensile and other properties. The separation layer should have better separation performance, otherwise, it will make the picture and text of hot stamping blurred, exposed the bottom hair, and affect the quality of hot stamping products.
The main components of the folding layer: film-forming, heat-resistant, transparent synthetic resins and dyes. The main role of the color layer has two: 1, color display. 2. Protect the aluminized coating from oxidation. The colors of the aluminum foil are orange, gray, red, green and so on. The color of the chromatic layer is given lustre after aluminizing layer, the color has certain change, such as yellow after aluminizing is gold, gray after aluminizing is silver, etc. The requirement of color coating is that there are no small particles in order to avoid the appearance of sand holes and destroy the uniformity of coating.
A folded aluminizing layer is a vacuum chamber in which a film with a chromatic layer, such as a chromatic layer, is placed in a continuous aluminizing machine. Under a certain vacuum degree, the aluminum wire is melted and continuously evaporated onto the chromatic layer of the film at a certain degree of vacuum, and an aluminized layer is formed. The main function is to reflect light, change the color of the color, and make it shine. The cladding layer is usually made of fusible thermoplastic resin (kind and variety) on aluminum layer by coating machine, which is then dried to form adhesive layer. The main function of the adhesive layer is to bind the hot stamping material to the hot object.
The selection of aluminum must pay attention to hot stamping substrate matching. What kind of substrate to choose the type and model of aluminum oxide is different. For example, the HB type of aluminum is used in fabric, and if you want to burn it on plastic, it certainly doesn't match. For example: music technology GS series is used on glass bottles you use on paper, that is not good. Therefore, in the selection of aluminum, in addition to considering the color and price of aluminum, hot stamping substrate and its surface state (whether in the printing ink layer, polished or coated surface hot stamping) must be made clear to the supplier.
