The surface hardening treatment of acrylic products. Acrylic is also called plexiglass or acrylic. It is a kind of polymer 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 of acrylic products. Treatment, also called surface coating. The following editor will give you the specific surface coating of acrylic products.
Acrylic hardening begins by using quartz material to coat the surface of acrylic products under vacuum conditions. Through this treatment, a very hard wear-resistant film can be formed on the surface of the acrylic sheet. 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 coat the surface of acrylic products with a high hardness and not easy through the immersion process. For brittle materials, 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. Embrittlement, 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 acrylic products is difficult to be scratched and 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 in the assembly proce
