Definitions

  • An object of the invention is to provide a gasket structure which consists of a combination of resilient soft material parts and hard material parts, and with which liquid leakage can be sufficiently prevented to ensure safe operation of the cell structure.
  • the invention features'a gasket structure which comprises a first gasket sub-structure consisting of a sheet ofa resilient, soft material having an excellent electric passages of one electrolytic or dialytic section or com insulating property and formed with holes constituting 3 common passages and a central opening and guide wall members made of a hard material difficult to deform and having an excellent electric insulating property, said members being formed with respective holes each communicating with the corresponding one of said holes formed in said sheet and with a guide passage clef fined by said sheet and the corresponding one of said members.
  • the gasket also includes a pair of second gasket substructures each including a second sheet of a hard material difficult to deform and having an excellent electric insulating property and a third sheet of a soft material, said second and third sheets being formed with holes forming said common passages and respective openings forming said compartment, the first subthe afore-said compartment, said further sheet being provided onthe side of the second sheet of the hard material opposite to the third sheet of the soft material.
  • hard material herein means a material having a such hardness that the hard material sheet itself is not substantially compressed when the associated soft material sheet is compressed when pressed by the hard sheet with such a fastening force as not to cause liquid leakage.
  • the hard material and soft material are distinguished from each other according to the compressive strain; the soft material should be compressed by pressing, whereas the hard material should not be substantially compressed. More specifically, when the soft material sheet is compressed by about 10 percent by pressing a stack of hard and soft material sheets, the hard material sheet should not be compressed more than 0.5 percent, desirably not more than 0.1 percent. Also, the guide wall members which are made ofa hard material should be thinner than the soft' material sheet.
  • FIG. 5 shows, in section, an electrolytic cell structure assembled from the afore-described gasket structures according to the invention.
  • a gasket structure 5 having holes 13, l4, l5 and 16 for the common passages and 36, for instance the one nearest to the left end, has its one side in contact with one side of a structure 6 having guide walls 28 and 29 and holes 23 and 26, whose other side is in turn in contact with another gasket structure 5b, which is the same as but inverted with I respect to the first structure 5.
  • This gasket structures comprises a gasket group, which has its one sidein 4 I contact with a composite electrode 38 and its other sidein contact with a partition wall 39, which is in turn in contact with a second gasket group having the same construction as but inverted with respect to the first.
  • An electrolytic cell structure as shown in FIG. 5 was constructed with a press. Heat-resisting vinyl chloride was used for the sheets 11, nitrile rubber for the sheets 12 and 21, and hard polyethylene rubber sheets for'the wall members 28 and 29.
  • the sheets 11 had a thickness of 1.0 mm, the sheets 12 a thickness of 0.2mm, the sheets 21 a thickness of 1.65 mm, and the wall members a thickness of 1.50 mm.
  • the dimensions ofthe gaskets were selected to be 300 mm X 600 mm, while the dimensions of the electrolytic compartments were made to be 200 mm X 300 mm.
  • the electrolytic cell structure of the above example was operated for 24 hours under predetermined conditions, namely using 5N. NaCl and 5N. NaOH respectively as cathodic and anodic liquids, at a liquid temperature of 70 C, at a current density of A/dm and at an average speed of liquid flow through the electrolytic compartments of 10 cm/sec.
  • 5N. NaCl and 5N. NaOH respectively as cathodic and anodic liquids
  • a gasket structure for preventing leaks comprising at least three gasket substructures, at least two of said substructures each including a first sheet of hard-material and a second sheet of soft material wherein said sheet of soft material is thinner than said sheet of hard material and wherein said first and second sheets have a central opening and guide.
  • said third gasket substructure having a centralopening and guide passages corresponding to said central opening and guide passages formed by said at least two gasket substructures wherein said guide wall members are positioned within the central opening of said soft sheet and at least one of the guide passages of said third gasket substructures commuyeres with said central opening.
