Abstract
The invention discloses a method for eliminating static electricity on thin films on line, aiming at overcoming the defect that the static electricity eliminating effect is not good when the existing static electricity eliminating method is adopted. Thermally treated carbon fibers are woven to obtain a conductive carbon fiber belt and the conductive carbon fiber belt is in contact with the thin films to lead out the static electricity. By adopting the method, the static electricity on the thin films can be eliminated very well without scratching the thin films.
Description
Technical field
The present invention relates to a kind of method of online elimination film static, be specifically related to a kind of method that makes the fricative static of the effective elimination of plastic film at cutting machine.
Background technology
Plastic film generally all is preferably material of insulation property, and these films are in the process of producing, because rubbing action, film surface will produce a large amount of static.The generation of static not only affects the normal running of foil producers, and the film of static electrification is easy to adsorb dust, affects cleanliness factor and the use in film later stage of film.When film take-up, film and film are attached together easily, affect the rolling effect; Have that high concentration is inflammable, in the rear course of processing of explosive solvent, static is easy to cause burning and blast.
The method of eliminating film surface static is a lot, is summed up and mainly contains following four aspects: use consumer appliance, add electrical static eliminator, surface-coated method in film, improve film production or processing conditions.For the film of having produced, mainly be to eliminate static with consumer appliance in the splitting winding operation, disclose a kind of static eliminator device that is installed on the cutting machine such as the patent application of CN201020262261; Consumer appliance mainly is two types of static eliminatory by corona discharge and radioisotope Xelminators.These two types all is by utilizing power supply or radioactive source, the positive and negative electric charge of generation is eliminated the electric charge on the film in air, and its advantage is not have contact membrane, can not cause scuffing to film, shortcoming is to come static on the neutralized film by airborne electric charge, and it is not obvious to eliminate electrostatic efficiency.
Summary of the invention
The problems referred to above that exist in order to solve prior art the purpose of this invention is to provide a kind of energy and directly contact with film, and the electric charge on the film flows out by conductor and do not scratch again film, can effectively eliminate the method for film static.
The method of online elimination film static of the present invention, comprise carbon content is 90 ~ 95%, becomes band to obtain the conductive carbon fibre band through heat treated carbon fiber knit, be fixed on the metal frame, before the rolling film rolling of cutting machine, with the one or both sides of the vertical contact membrane of conductive carbon fibre band difference.Wherein, the resistivity of described conductive carbon fibre band is 0.9 ~ 9 μ Ω m, width 20 ~ 70mm.
The present invention will become band to obtain the conductive carbon fibre band through heat treated carbon fiber knit, and it has the characteristics such as conductivity height, intensity height, light weight, softness, therefore can utilize this conductive carbon fibre band that the static on the film is imported in the ground.The method can well eliminate on the film with static and can not scratch film.
