How to prevent aging of anti-static plastic film
Anti-static plastic film is also called anti-static heat-sealing film, anti-static plastic film, anti-static plastic film, etc. Its main function is to use in products such as plastic documents and pictures. At present, anti-static plastic film has been widely used in various industrial fields to protect the surface of products.
Why should the anti-static plastic film be over-molded? Over-plasticizing photos or documents and work instructions can prevent fingerprints, stains, or scratches on photos, pictures and documents; a large number of items that are repeatedly contacted need to be protected, so that photos and documents will be stored for many years as new and will not fade , No damage; protect items that need to be placed in a clean room for a long time; more can prevent photos and documents from being damaged during transportation; this kind of products are mostly used in clean rooms or anti-static workshops.
The production process of anti-static plastic film and product delivery and use protection are of great significance to effectively reduce the production of defective products and increase product value. Therefore, it will inevitably age over time. What should you do in this situation?
Over plastic film is composed of plastic substrate and adhesive, which belongs to polymer material. Aging includes heat aging and ultraviolet aging. After the aging of the protective film, the polymer chains constituting the base material and the adhesive are broken, the average molecular weight decreases, and the cohesive strength decreases.
1. Solution: try not to expose the profile with plastic film and protective film to the sun, and peel off the protective film after installation.
2. Processing method: First, put the anti-static tears over the plastic film (the speed of the tear film on the surface of different glue residues, this profile is different, and the speed can be controlled), try to avoid processing difficulties caused by film rupture, and more Wipe with the "asphalt" cotton cloth, and then use a clean cotton cloth to wipe the surface of the detergent oil, try not to use a rough cloth to wipe the surface of the product as much as possible, otherwise the gloss of the product surface is easily damaged.
