Introduction of aluminum sheet protective film

  • The Aluminum sheet protective film is based on a polyethylene (PE) film with a specific formula, and polyacrylic acid (ester) resin is used as the main material of the pressure-sensitive adhesive. It is processed by packaging and other processes. The protective film is soft, has good adhesion, and is easy to stick and peel. The pressure-sensitive adhesive has good stability and will not have any adverse effect on the surface of the product to be pasted.

    Aluminum panel protective film is a layer of plastic film attached to the aluminum material. The purpose is to protect the produced aluminum material from damage during a series of processes such as handling, inventory, transportation, processing, and installation. It is torn off by the installer, so that the surface of the aluminum material is as smooth and clean as new, and has the proper decorative effect. There are many kinds of aluminum products on the market, and the surface treatment technology of aluminum products is also continuously improved. Various aluminum surface treatment technologies include: mechanical polishing, chemical polishing, anodizing coloring, electrophoretic painting, chemical coloring, fluorocarbon spraying, electrostatic powder spraying, surface pattern treatment, etc. Different aluminum surfaces need to choose different viscosity aluminum panel protective film. Protective Film for Aluminum Composite Panel is mainly used for surface protection of various plastic and wooden boards (sheets), such as: PVC, PET, PC, PMMA two-color board, foam board UV board, glass and other board surfaces during transportation and storage And no damage during processing and installation. The PE protective film products produced by Xinhao generally have 4 series of low viscosity, medium viscosity, high viscosity and extra high viscosity. The thickness is 4-12C (commonly used thickness is 8C/9C), so it is necessary to choose different Protective Film for Aluminum Composite Panel according to different surfaces of aluminum materials. Depending on the surface and film pressure, the viscosity rises at different speeds. 

    Generally, it should be placed for a sufficient time before peeling off the protective film to determine whether the viscosity is appropriate. For a certain surface, it is extremely important to choose the appropriate colloid and viscous PE protective film, and the subsequent processing steps are the key to determining the viscosity. The subsequent processing generally includes cutting, bending, drilling, punching, etc. Generally, low-viscosity PE protective film is selected for smooth surfaces, such as mechanical polishing and chemical polishing aluminum; medium-rough surfaces are selected for medium-viscosity PE protective films, such as anodizing coloring, electrophoretic painting, chemical coloring, fluorocarbon spraying, and smooth electrostatic powder spraying. Aluminum; for very rough surfaces, use high-viscosity aluminum panel protective film, such as electrostatic powder sandblasting aluminum; if laser cutting is required, because the protective film shrinks when exposed to heat, an extra-high-viscosity protective film should be used. In addition to viscosity, users also need to test the tensile strength and elongation of the protective film to ensure that the flexibility and strength of the protective film can meet the requirements for use.
