Abstract
An ionic membrane electrolytic bath rubber sheet gasket is a fillet rectangular loop made of ethylene propylene terpolymer with papilionaceous cross section, wherein, the ethylene propylene terpolymer papilionaceous loop is provided with a sealing line with O-shaped cross section; the two opposite sides of the O-shaped sealing line respectively facing towards the inside and outside of the loop are provided with radial flank vanes. During use, the radial flank vanes are in the same plane of the fillet rectangular loop; meanwhile, both the inner loop opening of the ethylene propylene terpolymer papilionaceous loop and the surfaces of the radial flank vanes of the O-shaped sealing line facing towards the inside of the loop are provided with fluoroplastics membranes. The utility model compounds sealing element of ethylene propylene terpolymer papilionaceous loop and anti-corrosive element of fluoroplastics and is very convenient for assembly during being assembled into electrolytic bath with pole plate.
Description
Technical field
The utility model relates to a kind of ion-exchange membrane electrolyzer rubber sheet gasket, particularly a kind of ion-exchange membrane electrolyzer rubber sheet gasket with the contacted trim of ionic membrane on the fluoroplastics protective film.
Background technology
In the prior art, chlor-alkali production ion-exchange membrane electrolyzer rubber sheet gasket by U.S. Occidental Petroleum Corporation (ELTECH Systemp Corpration) production, be to be that round rectangle ring and the cross section with matching that the ethylene-propylene diene copolymer of butterfly is made is that the round rectangle ring that the orthogonal fluoroplastics are made is composited with cross section, above-mentioned ethylene-propylene diene copolymer butterfly ring is that resilient material is made, be sealing member, above-mentioned fluoroplastics straight-flanked ring is anticorrosion.It is the potted line of " O " shape that cross section is arranged on the ethylene-propylene diene copolymer butterfly ring, the both sides of " O " shape potted line relative direction have the radial side fin respectively, when user mode, the radial side fin is on the plane at round rectangle ring place, have towards the narrow groove of intra-annular on the interior collar extension of ethylene-propylene diene copolymer butterfly ring, " O " shape potted line, the surface of a sidewall of narrow groove and the radial side fin of above-mentioned interior collar extension is on same plane, and the width of narrow groove is identical with the thickness of above-mentioned fluoroplastics straight-flanked ring.During use; above-mentioned fluoroplastics straight-flanked ring is inserted in the narrow groove of intra-annular, being combined with each other of " O " shape potted line of above-mentioned Ethylene Propylene Terpolymer butterfly ring; be clipped in and be assembled into electrolyzer between pole plate; ethylene-propylene diene copolymer butterfly ring plays sealing function, and the fluoroplastics straight-flanked ring plays the effect that protection ethylene-propylene diene copolymer butterfly ring is not subjected to the chlor-alkali dielectric corrosion.This ion-exchange membrane electrolyzer rubber sheet gasket is to be composited in the erecting stage with ethylene-propylene diene copolymer butterfly ring and fluoroplastics straight-flanked ring in use, the size of two round rectangle rings is big, the fluoroplastics straight-flanked ring is thin harder, ethylene-propylene diene copolymer butterfly ring is softer, makes the assembling of electrolyzer very inconvenient.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind of assembling that makes electrolyzer ion-exchange membrane electrolyzer rubber sheet gasket very easily.
The utility model is realized with the following method.
This ion-exchange membrane electrolyzer rubber sheet gasket, be that cross section is the round rectangle ring that the ethylene-propylene diene copolymer of butterfly is made, it is the potted line of " O " shape that cross section is arranged on this ethylene-propylene diene copolymer butterfly ring, " O " shape potted line in ring and the both sides of the relative direction outside encircling the radial side fin is arranged respectively, when user mode, the radial side fin is on the plane at round rectangle ring place, the interior collar extension of ethylene-propylene diene copolymer butterfly ring, " O " shape potted line are compounded with the fluoroplastics diaphragm on the surface of the inboard radial fins of ring.Fluoroplastics diaphragm-operated thickness is 0.1～1.0 millimeter.
The utility model is combined with each other ethylene-propylene diene copolymer butterfly annular seal and fluorine plastic corrosion-proof spare, and is when being assembled into electrolyzer with pole plate, need not on-the-spot compound installation very convenient.
Below in conjunction with accompanying drawing, the utility model is further described.
