Description
Technical field
The utility model relates to cell technologies field, specifically a kind of anode rubber sheet gasket being provided with tetrafluoroethylene adhesive tape.
Background technology
, owing to being subject to chlorine contained in electrolytic solution and chlorous long-term corrosion, can there is the problem that stopping property reduces in the rubber sheet gasket of the anode side of common ion-exchange membrane electrolyzer, therefore, need exploitation can keep the structure of excellent sealing.
Summary of the invention
The utility model, for overcoming the deficiencies in the prior art, on rubber sheet gasket surface, covers the poly tetrafluoroethylene of one deck excellent durability, pad directly cannot be contacted with electrolytic solution, can provide rate of utilization like this, is convenient to produce.
For achieving the above object, design a kind of anode rubber sheet gasket being provided with tetrafluoroethylene adhesive tape, comprise shim body, poly tetrafluoroethylene, it is characterized in that: be long strip shape ethylene-propylene-diene monomer glue gasket in shim body, upper surface and the inner side of shim body are respectively equipped with poly tetrafluoroethylene; The length of the poly tetrafluoroethylene of described shim body upper surface is 3 ~ 10 millimeters; The length of the poly tetrafluoroethylene of described shim body medial surface is 3 millimeters.
The outer side of described shim body is smooth flat.
The thickness of described poly tetrafluoroethylene is 0.05 ~ 0.5 millimeter.
The utility model compared with the existing technology, on rubber sheet gasket surface, covers the poly tetrafluoroethylene of one deck excellent durability, pad directly cannot be contacted with electrolytic solution, can provide rate of utilization like this, is convenient to produce.
This pad is EPDM material, i.e. ethylene-propylene-diene monomer glue gasket, and erosion resistance is fine, work-ing life is generally greater than 4 years, but in the side of pad and electrolyte contacts, sometimes has corrosion and occur, therefore, increase the design of poly tetrafluoroethylene, isolated electrolytic solution contacts with the direct of pad side.
Pad up and down and side be all level and smooth, without decorative pattern, smoothly can to fit with flange face more closely, prevent the crevice corrosion of flange face.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 be in Fig. 1 A-A to sectional view.
See Fig. 1, Fig. 2,1 is shim body, and 2 is poly tetrafluoroethylene.
Embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Fig. 1, Fig. 2, be long strip shape ethylene-propylene-diene monomer glue gasket in shim body 1, the upper surface of shim body 1 and inner side are respectively equipped with poly tetrafluoroethylene 2; The length of the poly tetrafluoroethylene 2 of described shim body 1 upper surface is 3 ~ 10 millimeters; The length of the poly tetrafluoroethylene 2 of described shim body 1 medial surface is 3 millimeters.
The outer side of shim body 1 is smooth flat.
The thickness of poly tetrafluoroethylene 2 is 0.05 ~ 0.5 millimeter.
On shim body 1 surface, cover the poly tetrafluoroethylene 2 of one deck excellent durability, shim body 1 directly cannot be contacted with electrolytic solution, can rate of utilization be provided like this, be convenient to produce.
This shim body 1 is EPDM material, i.e. ethylene-propylene-diene monomer glue gasket, erosion resistance is fine, work-ing life is generally greater than 4 years, but in the side of shim body 1 and electrolyte contacts, sometimes have corrosion and occur, therefore, increase the design of poly tetrafluoroethylene 2, isolated electrolytic solution contacts with the direct of side of shim body 1.
Shim body 1 up and down and side be all level and smooth, without decorative pattern, smoothly can to fit with flange face more closely, prevent the crevice corrosion of flange face.
