This invention relates to a chlorine and water resistant soft packing that is used in charging and discharging cells and has excellent chlorine gas and chlorine water resistance, and is soft and maintains compressive deformation resistance and watertight sealing properties.

。Fluororesins such as PTFE, ETFE, and FEP have hardness (
Since it is hard with a Shore D ) of about 60 and is a thermoplastic resin, it is not suitable as a sealing packing because it causes a creep phenomenon if the compressive strength and deformation amount are large. Furthermore, PVC, PVDC, etc. have even higher hardness and cannot be used as packing materials at all. Heat-crosslinked fluororubber is used as a sealing packing with rubber elasticity, but it swells with saturated chlorine water and has poor liquid sealing properties.

の耐塩素水性パツキンが必要となる。In particular, in liquid circulation power storage batteries that use a chemical reaction between zinc and chlorine, battery cells that circulate saturated chlorine water are stacked, so the sealing of the electrolyte between each cell must be ensured.
Stable charge/discharge characteristics cannot be obtained. Furthermore, since saturated chlorine water is used, metal materials other than Ti cannot be used due to corrosion. Furthermore, since Ti also has the problem of electrolytic corrosion, organic polymeric materials with good resistance to saturated chlorine water are used for the piping, containers, and electrode holders that constitute the battery equipment. Therefore, a soft, chlorine-resistant, water-resistant packing with excellent liquid sealing properties between organic polymer materials is required.

。Moreover, in order to increase the capacity of the battery, the electrode area must also be increased, and the packing and O-rings cannot be made by compression molding.
After extrusion molding a string-like packing, it is cut to the required length and connected to be used as a packing. In this way, a gasket that can be connected during use is required.
