Abstract
The utility model relates to a novel low calcium and magnesium rubber pad, which is used as the positive electrode of an enforced circulation bipolar type and natural circulation bipolar type ion membrane electrolysis tank. The utility model comprises a rubber pad main body 1 and a thin membrane layer 2 wrapped on the outer surface of the main body of the rubber pad. The utility model is characterized in that the thin membrane layer 2 adopts the non-connector wrapping at whole corner parts. The thin membrane layer 2 adopts the copolymer thin membrane of tetrafluorethylene and PFF Phenol-furfural ethylene. The utility model avoids the problem that chlorine and sodium hypochlorite is interfused from the corner connector to corrode the washer, thereby guaranteeing the rubber pad to have longer service life and better sealing effect.
Description
(1) technical field: the utility model relates to a kind of rubber pad.Be specifically related to a kind of novel Low calcium maglnesium rubber pad.The anode that is used for pump circulation multipole type and natural circulation a bipolar type ion-exchange membrane electrolyzer.
(2) background technology: at present, be used for the rubber pad of list, a bipolar type ion-exchange membrane electrolyzer, generally partly form the rubber pad body by skeleton and ethylene-propylene diene copolymer two.Because clorox in the ion-exchange membrane electrolyzer and chlorine are to the corrosion especially severe of rubber, the work-ing life of rubber pad is extremely short, generally is no more than 1 year.Like this, long by the replacement cycle of daughter ion film on the one hand, be generally 3 years, pad does not reach the requirement of synchronous use, causes repeatedly to shut down and changes pad, influences the production of streamline, reduces productivity effect.On the other hand, after pad was corroded, its composition decomposed to produce and goes influence product, quality in the solution.In addition, after rubber erodes, skeleton is exposed, cause the breakage of ionic membrane, changing ionic membrane has increased production cost again.At the problems referred to above, the ZL00221245.5 patent has proposed a kind of terms of settlement, coats a polytetrafluoroethylene film layer at this external surface of rubber pad exactly.Though this method corresponding work-ing life that prolongs rubber pad, because tetrafluoroethylene has chlorine, and the pad inboard is divided into four sections films and coats, and there is interface in the bight, can not fundamentally solve chlorine and bight etching problem.
(3) summary of the invention: the purpose of this utility model is to provide a kind of more corrosion resistant novel Low calcium maglnesium rubber pad.Technology contents of the present utility model is: a kind of novel Low calcium maglnesium rubber pad, comprise rubber pad body and the thin film layer that is coated on this external surface of rubber pad, and be characterized in that thin film layer adopts the whole piece bight not have interface and coats.Film of the present utility model adopts the copolymer film of tetrafluoroethylene and perfluoroalkyl ethylene oxy, is called for short the PFA film.
Compare with existing Low calcium maglnesium rubber pad, the utlity model has following advantage:
1, thin film layer adopts the whole piece bight not have the interface coating, has stopped chlorine and clorox infiltrate the corrosion pad from the bight interface problem.
2, because the PFA film has good chemical reagent-resistant performance and high mechanical strength, and the use temperature scope is wide, saturating anything but chlorine.
3, because the utility model is increased the sealing lines, the solution in the blocking-up ionic membrane micropore is to exosmosis, but to electric groove pressure and pole span not influence again.
Therefore, the utility model has fundamentally solved saturating chlorine and bight etching problem.Thereby guaranteed that rubber pad has long work-ing life and good sealing effectiveness.

Fig. 1 is an overall structure synoptic diagram of the present utility model.
Fig. 2 is the A-A cut-away view of Fig. 1.
(5) embodiment:
Referring to Fig. 1, the utility model is a kind of novel Low calcium maglnesium rubber pad, and it mainly is made up of copolymer film layer 2 (being called for short the PFA film) two portions of rubber pad body 1 and tetrafluoroethylene and perfluoroalkyl ethylene oxy.The PFA thin film layer is coated on the outside surface of rubber pad body.Solution and rubber pad are kept apart fully.The PFA rete preferably is coated on medial surface that rubber pad contacts with solution and the upper and lower surface that links to each other with medial surface.The PFA thin film layer adopts whole piece bight 3 no interfaces to coat.Rubber pad body 1 is higher than both sides 5 by the sealing lines middle 4 of ionic membrane one side.
Claims (5)
1, a kind of novel Low calcium maglnesium rubber pad comprises rubber pad body (1) and is coated on the thin film layer (2) of rubber pad body (1) outside surface, it is characterized in that thin film layer (2) adopts the no interface coating in whole piece bight (3).
2, a kind of novel Low calcium maglnesium rubber pad according to claim 1 is characterized in that thin film layer (2) adopts the copolymer film of tetrafluoroethylene and perfluoroalkyl ethylene oxy.
3, a kind of novel Low calcium maglnesium rubber pad according to claim 1 and 2 is characterized in that thin film layer (2) is coated on medial surface that rubber pad contacts with solution and the upper and lower surface that links to each other with medial surface.
4, a kind of novel Low calcium maglnesium rubber pad according to claim 1 and 2 is characterized in that rubber pad body (1) is higher than both sides (5) by (4) in the middle of the sealing lines of ionic membrane one side.
5, a kind of novel Low calcium maglnesium rubber pad according to claim 3 is characterized in that rubber pad body (1) is higher than both sides (5) by (4) in the middle of the sealing lines of ionic membrane one side.
