Acrylic is a high-molecular polyester compound. Because the hardness is not very high, it is also prone to scratches, so the surface is hardened. This process is called surface hardening treatment of acrylic products, also called surface coating. The following editor will introduce to you the surface coating of acrylic candy box.
Acrylic hardening starts by using quartz material to coat the surface of the acrylic candy box under vacuum conditions. Through this treatment, a very hard wear-resistant film can be formed on the surface of the acrylic plate. Later, the original process was improved. In order to make the acrylic surface harder and less susceptible to scratches, it was decided to upgrade the surface hardening process. This hardening process is to plate a high hardness and high hardness on the surface of the acrylic candy box through a soaking process. For materials that are not easily brittle, this method is better than the coating of quartz materials, and the process will not be as troublesome as quartz materials.
However, due to the inability of this technology to keep up with the output and other reasons, a third acrylic surface hardening process was discovered. This process is due to the fact that the friction between the reflective film and the acrylic plate base is low and the sheet material after this process is coated is low and difficult. Fragile cracking. Until now, organic substrates have been used to coat the surface. This kind of coating containing organic oxide particles is currently a more widely used process. After coating, the surface of the acrylic candy box is difficult to be scratched and it is not easy to be brittle .
    Acrylic sheet has a certain expansion coefficient, so in the process of use and installation, the thermal expansion and contraction factors of acrylic sheet must be taken into account, and there must be a space for expansion and contraction when assembling. This is also a detail that needs to be paid attention to during the assembly process of the acrylic candy box.
