Abstract
The utility model relates to an ionic membrane electrolysis bath sealing pad which is clung on a unit slot sealing surface of an ionic membrane electrolysis bath to play a sealing role. The sealing pad comprises a polytetrafluoroethylene plate (2), wherein one surface of the polytetrafluoroethylene plate (2) is compounded with an EPT rubber layer (1), the surface of the EPT rubber layer (1) is manufactured into sawtooth shaped stripes, and the middle portion of the other surface of the polytetrafluoroethylene plate (2) is compounded with a polytetrafluoroethylene elastic strip (3). The ionic membrane electrolysis bath sealing pad of the utility model can not generate corrosion and can be conveniently replaced.
Description
(1) technical field
The utility model relates to a kind of ion-exchange membrane electrolyzer, especially relates to a kind of ion-exchange membrane electrolyzer gasket seal, is fitted on the unit groove trim of ion-exchange membrane electrolyzer to seal.Belong to technical filed of chlor-alkali equipment.
(2) background technology
A bipolar type ion-exchange membrane electrolyzer is the chlorine industry specific equipment, produces caustic soda (NaOH) and chlorine (cl by electrolytic brine (Nacl)
2) etc.The ion-exchange membrane electrolyzer gasket seal has two kinds on negative electrode pad and anode pad.It uses pattern to be: stick the cathode and anode pad on the unit groove trim, between the cathode and anode pad ionic membrane is housed, by oil press or pull bar locking, reach sealing function then.Its environment for use is as follows:
The sodium hydroxide solution that the contact of negative electrode pad is 90 ℃.
Chlorine, hydrochloric acid, sodium-chlor and clorox etc. that the contact of anode pad is 90 ℃.
The problem that the anode pad exists is:
1, the inboard corrosion prevention film that coats of anode pad, every pad has an interface, and the glue of interface is immersed in and has the electrolytic solution infiltration in the liquid;
If local uneven when 2, pasting pad, the edge of corrosion prevention film is attached in the electrolyzer, electrolytic solution can infiltrate;
3, the minority corrosion prevention film breakage that causes in process of production;
4, because of other reason causes parking, need take electrolyzer apart, if pad uses for some time (more than 6 months), pad is pressurized, need more change;
5, reason to sum up because an electrolyzer is made up of tens to up to a hundred unit grooves, as long as wherein there is part (or several) pad that problem is arranged, promptly can causes electrolyzer to leak and stops;
6, the pad inboard produces the crystallization knurl because of the damaged local corrosion of corrosion prevention film, causes the infringement (local extruding causes the film breakage) to ionic membrane.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can not produce corrosion and change ion-exchange membrane electrolyzer gasket seal easily.
The purpose of this utility model is achieved in that a kind of ion-exchange membrane electrolyzer gasket seal, comprise polyfluortetraethylene plate, the compound one deck ethylene-propylene-diene monomer of the one side of polyfluortetraethylene plate glue-line, this terpolymer EP rubber laminar surface is made the spination striped, compound one deck tetrafluoroethylene elastic strip in the middle of the another side of polyfluortetraethylene plate plate.
During use, the ethylene-propylene-diene monomer glue-line of gasket seal is fitted by tackiness agent with the trim of electrolyzer towards the trim of electrolyzer, and the tetrafluoroethylene elastic strip of gasket seal is towards ionic membrane.
The purpose of this utility model beneficial effect is:
1, its material of part because of gasket seal contact electrolytic solution is a tetrafluoroethylene, can not produce corrosion, has guaranteed can not cause parking because of the pad reason in the electrolyzer operational process;
2, because of other reason causes parking, shim body need not changed, only need change the tetrafluoroethylene elastic strip.
3, through the pad of first phase ionic membrane operation life use, can utilize the compound again ethylene-propylene-diene monomer glue-line of tetrafluoroethylene plate portion of gasket seal, reach the reparation purpose of usefulness again.
(4) description of drawings
Fig. 1 is the orthographic plan of the utility model ion-exchange membrane electrolyzer gasket seal.
Fig. 2 is the A-A cut-away view of Fig. 1.
Reference numeral among the figure:
Ethylene-propylene-diene monomer glue-line 1
Tetrafluoroethylene elastic strip 3.
(5) embodiment
Referring to Fig. 1～2, Fig. 1 is the orthographic plan of the utility model ion-exchange membrane electrolyzer gasket seal.Fig. 2 is the A-A cut-away view of Fig. 1.By Fig. 1 and Fig. 2 as can be seen, the utility model ion-exchange membrane electrolyzer gasket seal, comprise polyfluortetraethylene plate 2, the compound one deck ethylene-propylene-diene monomer of the one side of polyfluortetraethylene plate 2 glue-line 1, the spination striped is made on this ethylene-propylene-diene monomer glue-line 1 surface, applying last layer tetrafluoroethylene elastic strip 3 in the middle of the another side of polyfluortetraethylene plate plate 2.
Claims (1)
1. ion-exchange membrane electrolyzer gasket seal, it is characterized in that described gasket seal comprises polyfluortetraethylene plate (2), the compound one deck ethylene-propylene-diene monomer of the one side glue-line (1) of polyfluortetraethylene plate (2), the spination striped is made on this ethylene-propylene-diene monomer glue-line (1) surface, compound one deck tetrafluoroethylene elastic strip (3) in the middle of the another side of polyfluortetraethylene plate plate (2).
