Abstract
A full enclosed seal gasket of an ion-exchange membrane electrolyzer relates to a structural improvement of a full enclosed rubber seal gasket of an ion-exchange membrane electrolyzer. The full enclosed seal gasket is fine in anti-corrosion effect and provided with polar plates, and the rubber seal gasket is arranged between the polar plates. The full enclosed seal gasket is characterized in that the outer surface of the rubber seal gasket is coated with a polytetrafluoroethylene (PTFE) or fluorinated ethylene propylene copolymer (FEP) or polyfluoroalkoxy (PFA) film.
Description
Technical field:
The utility model relates to the improvement of structure of the rubber gasket of Totally-enclosed ion membrane electrolyser.
Background technology:
Because clorox and chlorine in the ion-exchange membrane electrolyzer corrode especially severe to rubber gasket, cause the rubber seal pad life shorter, generally are no more than 1 year; In addition, after rubber gasket was corroded, its composition had influenced the quality of product to producing in the solution.At present, Chinese patent 02218295.0 is arranged, there is not the coating of interface at the copolymer film whole piece of rubber gasket inboard employing tetrafluoroethylene and perfluoroalkyl ethylene oxy, mainly prevent rubber gasket and produce the corrosion that solution contacts, improved the life-span of rubber gasket, but the rubber gasket outside does not coat film, still can be corroded by electrolytic solution, influences the quality and the ordinary production of product.
Summary of the invention:
The utility model is exactly at the problems referred to above, and the full coating gasket of the good ion-exchange membrane electrolyzer of a kind of anticorrosion ability is provided.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises pole plate, between the pole plate rubber gasket, the film of totally-enclosed coating polytetrafluoroethylene (PTFE) of its structural feature rubber gasket outside surface or fluorinated ethylene propylene copolymer (FEP) or tetrafluoroethylene-perfluorinated alkoxy vinyl ether copolymer (PFA).
The beneficial effects of the utility model:
Because the film of the totally-enclosed coating polytetrafluoroethylene (PTFE) of the utility model rubber gasket outside surface, fluorinated ethylene propylene copolymer (FEP), tetrafluoroethylene-perfluorinated alkoxy vinyl ether copolymer (PFA), just rubber gasket all can be sealed, not only prevent the corrosion of solution leakage, and guaranteed that the quality of producing reaches normal operation in rubber gasket inside.
