Abstract
The utility model relates to a semi-coating complex polarization type of ionic membrane channel rubber washer which has a rectangular ring with a cross section of rectangle. At two sides of the rubber washer is respectively installed a sealing plane respectively contacting a polar plate and an ionic membrane on which is equipped a sealing line. The internal ring pot of the rectangular ring at the rubber washer is wrapped with a fluoroplastics membrane one lateral plane of which is wrapped in a basal body of the rubber washer and the other lateral plane is combined on the surface of the sealing plane contacting the ionic membrane. Because no fluoroplastics membrane is coated on the surface of the sealing plane at the utility model contacting the polar plate, in case of assembling an electrolytic cell, the complex polarization type of ionic membrane channel rubber washer is easy to be adhered to the polar plate, beneficial to the assembly of electrolytic cell. Because the sealing line, with a cross section of trapezoid, at the sealing plane installed at the utility model to contact the polar plate, is not wrapped by a fluoroplastics membrane, the sealing line made of rubber has a superior elasticity and a well sealing performance when used for assembling the electrolytic cell.
Description
Technical field
The utility model relates to a kind of a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket, the fluorine plastic film that coats on particularly a kind of interior collar extension of straight-flanked ring of a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket.
Background technology
The chlor-alkali production of being produced by company of Asahi Chemical Industry of Japan is that cross section is the orthogonal straight-flanked ring with a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket, the both sides of a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket have respectively and pole plate and the contacted trim of ionic membrane, with being evenly equipped with cross section on the contacted trim of pole plate is the trapezoid potted line, with being evenly equipped with cross section on the contacted trim of ionic membrane is leg-of-mutton potted line, for anticorrosion, on the interior collar extension of the straight-flanked ring of a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket, be coated with fluorine plastic film.In the prior art, two sides that are coated on the fluorine plastic film of collar extension in the straight-flanked ring be compounded in respectively with the contacted trim of ionic membrane and with the surface of the contacted trim of pole plate on.The lip-deep fluorine plastic film that is compounded in the contacted trim of ionic membrane has solved the etching problem of medium to rubber sheet gasket preferably, but the lip-deep fluorine plastic film that is compounded in the contacted trim of pole plate has following deficiency: 1. during the assembling electrolyzer, the contacted trim of a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket and pole plate will adhere on the pole plate with tackiness agent, this lip-deep fluorine plastic film surface is poor with the wetting property of tackiness agent, thereby be difficult for adhering on the pole plate, influence the assembling of electrolyzer; 2. the poor flexibility of fluorine plastic film, be assembled into electrolyzer after, with the cross section that is coated with fluorine plastic film on the contacted trim of pole plate be that the contacted trim sealing property of trapezoid potted line and pole plate is not fine.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, after proposing a kind ofly to adhere on the pole plate easily, being assembled into electrolyzer, and the partial veil a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket of good seal performance.
The utility model is realized with the following method.
Partial veil a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket is that cross section is the orthogonal straight-flanked ring, the both sides of partial veil a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket have respectively and pole plate and the contacted trim of ionic membrane, with being evenly equipped with cross section on the contacted trim of pole plate is the trapezoid potted line, with being evenly equipped with cross section on the contacted trim of ionic membrane is leg-of-mutton potted line, on the interior collar extension of the straight-flanked ring of partial veil a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket, be coated with fluorine plastic film, a side of fluorine plastic film is that another side of fluorine plastic film is to be enclosed in the matrix of rubber sheet gasket on the surface that is compounded in the contacted trim of ionic membrane.
On the interior collar extension of straight-flanked ring of the present utility model, a side of the fluorine plastic film that coats be compounded in the surface of the contacted trim of ionic membrane on, another side is to be enclosed in the matrix of rubber sheet gasket, the fluorine plastic film that does not have coating on the surface of the utility model and the contacted trim of pole plate, during the assembling electrolyzer, the a bipolar type ion-exchange membrane electrolyzer rubber sheet gasket is easy to adhere on the pole plate, helps the assembling of electrolyzer; Cross section on the contacted trim of the utility model and pole plate is not coat fluorine plastic film on the trapezoid potted line, the potted line good springiness of elastomeric material, be assembled into electrolyzer after, sealing property is better.
Below in conjunction with accompanying drawing, the utility model is further described.
