1. Any product has a shelf life, and aluminum composite panel protective film is no exception. The protective film is mainly composed of plastic film and pressure sensitive adhesive. Plastic films and pressure-sensitive adhesives are all high-molecular compounds, both of which are aging. If the time is too long to exceed the shelf life, the performance of the protective film will decrease due to aging. For example, the plastic film becomes brittle and the adhesive force of the pressure sensitive adhesive becomes weak, which will affect the protective effect of the protective film on the surface of the aluminum-plastic composite panel. Therefore, the shelf life management should be strengthened when using the protective film, and the batch should be as accurate as possible when ordering the protective film, and it should not be too large to avoid the backlog of the expired protective film. When using, insist on using the protective film that is put in first, and use the protective film that is put in later to avoid the expiration of the protective film that is put in first. Pay attention to the stacking height in warehouse, generally not more than 2m. The warehouse of the aluminum-plastic composite panel manufacturer requires dry, cool, ventilated, and away from heat sources.
2. After the construction is completed with building decoration materials, the surface protective film is generally torn off within 45 days to avoid prolonged exposure to the sun and rain after construction, which may cause the aging of the surface protective film plastic or glue. The protective film is generally required to be torn off at an angle of 60° to 90°, not on the same plane as the decorative material. What should I do if the protective film of the aluminum composite panel cannot be peeled off?
3. The protective film of the aluminum composite panel should be torn off as soon as possible after the decoration is completed. If the time is too long, the protective film of the aluminum composite panel will be weathered and dry and difficult to remove. You can scrub the surface of the aluminum composite panel with hot water, and then slowly Slow tearing, usually clean.
4. Locate the broken ends and gently pull them apart. Use a hair dryer to blow along the horizontal stripes of the film (the direction that is not suitable for breaking). Just slightly heat it. Lift both ends with both hands and pull them down gently (push evenly, Don't pull it off), if the area is large, blow it piece by piece while pulling it.
