Application of aluminum profile protection film in aluminum industry

The aluminum profile protection 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. After the aluminum installation is completed, It is torn off by the installation engineering team, so that the surface of the aluminum material is as clean as new and has the decorative effect.

There are many types of aluminum products on the market, and aluminum surface treatment technology is constantly improving. China's various aluminum surface treatment technologies include: mechanical polishing, chemical polishing, anodizing coloring, electrophoretic painting, chemical coloring, fluorocarbon spraying, electrostatic powder coating, surface pattern processing, etc. Different aluminum surfaces need to use different viscosity Aluminium profile protection film.

Aluminum profile protective film products generally have 4 series of low viscosity, medium viscosity, high viscosity and extra high viscosity; the colors are transparent, milk white, blue, black and white, etc.; the thickness is 30 ~ 200μm, so it needs different surface according to aluminum Choose a different protective film. Depending on the surface and film pressure, the rate of increase in viscosity varies. Generally, it should be left for a sufficient period of time before peeling off the protective film to determine if the viscosity is suitable.

For a given surface, it is extremely important to choose the appropriate colloid and viscous protective film. Subsequent processing steps are the key to determining the viscosity. Subsequent processing generally involves cutting, bending, drilling, stamping, and the like. Generally, the smooth surface is made of low-viscosity protective film, such as mechanical polishing and chemical polishing aluminum; medium-rough surface is made of medium-viscosity protective film, such as anodizing, electrophoretic painting, chemical coloring, fluorocarbon spraying, smooth electrostatic powder coating aluminum. Very rough surface is selected from high-viscosity protective film, such as electrostatic powder sandblasted aluminum; if laser cutting is required, the protective film should be specially heat-shrinked, so a special high-viscosity protective film should be used.www.xmlfilm.com
