Description
Technical Field
[0001] The utility model relates to the technical field of film production equipment, in particular to a PVC film roll anti-static structure. Background Art
[0002] PVC film is a film material made of polyvinyl chloride. This material is widely used in many industries due to its excellent properties such as high transparency, good chemical resistance, waterproofness, and flame retardancy.
[0003] During the production process of PVC film, especially in the winding stage, if there is static electricity, it will cause the film layers to attract each other, causing the film layers to stick together and be difficult to separate, affecting subsequent processing and use. In the winding process, static electricity may cause wrinkles or distortions on the film surface, affecting the flatness and smoothness of the film. Static electricity may also cause the edges of the film to fold or warp irregularly, resulting in uneven winding, affecting the appearance and performance of the film. At the same time, statically charged films are prone to adsorb dust and impurities in the air, causing the film surface to become dirty, affecting the transparency and optical properties of the film.
