Description

Technical Field

[0001] The utility model relates to the technical field of dust removal on the surface of polyimide films, in particular to a dust removal device for polyimide films. Background Art

[0002] The polyamic acid solution is cast into a film and stretched, and then imidized at high temperature. The film is yellow and transparent, with outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties. The polyimide has stable chemical properties. Polyimide can prevent combustion without adding a flame retardant. General polyimides are resistant to chemical solvents such as hydrocarbons, esters, ethers, alcohols and chlorofluorocarbons. They are also resistant to weak acids, but are not recommended for use in strong alkali and inorganic acid environments.

[0003] During the production process of polyimide films, due to the production environment, some dust will adhere to the film surface. During long-term operation, if the dust on the polyimide film surface cannot be removed in time, it will affect the finished product quality of the film, thereby reducing the use effect of the film. Therefore, a dust removal device is used. However, the existing dust removal devices have poor dust removal effect, low dust removal efficiency, and static electricity will be generated due to the friction of the rollers during the dust removal process. Therefore, a more efficient dust removal and static electricity removal device is needed. Summary of the Invention
