Definitions

  • the invention relates to a cathode sheet for the electrolytic production of zinc, with a Aluminum plate and one on at least one Edge of the plate melted around it Insulation strip made of plastic.
  • DE-A-2558694 is a deposition cathode known, which has a deposition body, the one made conductive on both sides with one Copolymer of butene-1 and ⁇ -olefin coated aluminum sheet is formed, with an edge strip the same copolymer, only without conductivity additives, is applied on this coating.
  • a cathode sheet insulated at the edge which has a layer of polyethylene with a low molecular weight of 2 ⁇ 10 4 and was melted onto the surfaces to be insulated, a strip of polyethylene with a higher molecular weight being applied via this layer was pushed between 1x10 6 and 5x10 6 .
  • copolymeric polyolefin / aluminum pairing proves compared to each other as particularly liquid-tight the aggressive sulfuric acid electrolyte.
  • the insulation strip includes a layer on the sheet metal side consists of the copolymeric polyolefin and otherwise made of ordinary polyolefin. This design is very inexpensive because less of the expensive copolymer Polyolefin is necessary.
  • the insulation strip consists entirely of the highly adhesive polyolefin.
  • This type of construction can be used for large quantities sheet metal to be produced particularly inexpensively because simple. are manufactured.
  • the used Manufacturing process carried out according to the invention is that the insulation strip is extruded and after extrusion on the edges of the cathode sheet metal strip while still hot (e.g. at temperatures between 100 and 200 ° C, preferably 160 and 180 ° C, for 1 to 5 min), the sheets cut and then brackets on the narrow side surfaces of the cathode sheet are welded on, which are provided with an insulation strip Connect narrow side surfaces.
  • Copolymeric polyolefins in the sense of the invention are copolymers of olefin and adhesive additives for Metal surfaces. These are additives aliphatic carboxylic acids in an amount of 1 to 10 %, for example acrylic acid or its derivatives. Instead of acrylic acid can also esters such as. B. vinyl acetates to be available. Vinyl acetate can also coexist Acrylic acid is present, as are others Terpolymers in question. Ultimately, those are suitable Hot melt adhesive based on polyolefin, in which sufficient corrosion resistance is guaranteed is.
  • a cathode plate with a plate 1 made of aluminum is in an electrolyte 2 in a tub 3 on busbars 4, 4 'arranged with its holder 5 and has insulation strips on both vertical narrow sides 6, 6 'attached from polyolefin.
  • FIG. 2 shows an embodiment of the cathode sheet, which on the side edge of the aluminum plate 1 a uniformly made of highly adhesive copolymer Polyolefin melted existing insulation strip is.
  • the insulation strip can be extruded and melted using the extrusion heat be.
  • the insulation strip 3 is on the aluminum plate 1 of the cathode sheet a layer 7 of adhesive copolymer Polyolefin arranged and over this one the body the insulation strip is mainly constituted by U-shaped Slide 8 pushed on.
  • the postponement takes place in the heat, preferably using extrusion heat.
