PE protective film is a layer of plastic film on the aluminum plate, mainly to protect the production and manufacture of good aluminum in the loading and unloading, inventory, transportation, processing, installation and a series of whole process will not be damaged, in the aluminum installation is completed, by the installation workers tear off, and then make the surface of the aluminum smooth as new mouth, play the actual effect of decoration design.

Silicone protective film

There are a variety of aluminum products on the market, and aluminum surface treatment technology has been continuously improved. A variety of aluminum surface treatment technology includes: grinding polishing, chemical polishing, anodic oxidation treatment coloring, electrophoretic painting, organic chemical coloring, fluorocarbon spraying, electrostatic powder spraying, surface pattern processing, different aluminum surface need to choose different viscous PE protective film. PE protective film products generally have low viscosity, medium viscosity, high viscosity and extra high viscosity 4 series of products; The colors are transparent, milky white, dark blue, black and white, etc. Thickness is 4-12C (common thickness is 8C/9C), so it is necessary to choose different PE protective film according to the different surface of aluminum.

According to the different surface and film pressure, the viscosity rise rate is different. Generally, it should be placed after sufficient time and then separated from the protective film to determine whether the viscosity is suitable. For a certain surface, it is very important to select the appropriate colloid and viscous PE protective film. The follow-up processing process is the important decision of viscosity. The follow-up processing generally includes laser cutting, sheet metal bending, punching, stamping die, etc.

General smooth surface selection of low viscosity PE protective film, such as grinding polishing, chemical polishing aluminum; Medium level of non-smooth surface selection of adhesive PE protective film, such as anodic oxidation treatment coloring, electrophoretic painting, organic chemical coloring, fluorocarbon spraying, bright surface electrostatic powder spraying aluminum; Very not smooth surface selection of high stick PE protective film, such as electrostatic powder sandblasting aluminum; If it is necessary to carry out fiber laser cutting, because the protective film meets the heat shrink film, so the protective film should be choose with high viscosity. In addition to viscosity, the customer also needs to test the tensile strength and elongation of the protective film to ensure that the flexibility and compressive strength of the protective film can meet the application standards.
