Definitions

  • the invention relates to a cathode sheet for the electrolytic production of zinc, with a plate made of aluminum and an insulating strip made of plastic melted on at least one edge of the plate surrounding it.
  • insulating strips are arranged at the edges. This is necessary in order to prevent the zinc deposited on the cathode surfaces from growing in the direction of the anode plate or electrolyte trough and thereby producing a short circuit. These insulation strips are either snapped onto the edges of the cathode sheet or pressed on. Versions with screwed insulation strips are also known. These insulation strips themselves are made of plastic, rubber or wood.
  • a cathode plate of the type mentioned is known from DE-A-3 219 300.
  • the cathode sheets are immersed in sulfuric acid, which is used as the electrolyte, the aluminum corrodes. This corrosion occurs preferentially under the strips. This is because the acid penetrates between the sheets and the insulation strips and causes the aluminum to corrode very quickly. There is therefore an early failure of the cathode sheet, since the edges erode, the strip loses its grip on the sheet and thus there is a short circuit when the insulation strip between the growing zinc and the anode plate or electrolyte tray breaks away.
  • copolymeric polyolefin / aluminum proves to be particularly liquid-tight against the aggressive sulfuric acid electrolyte.
  • the insulation strip on the sheet metal side comprises a layer of the copolymeric polyolefin and, moreover, it consists of ordinary polyolefin.
  • This design is very inexpensive because less of the expensive copolymeric polyolefin is required.
  • the insulation strip consists entirely of the highly adhesive polyolefin.
  • the manufacturing process used for this purpose is carried out according to the invention in such a way that the insulation strip is extruded and after the extrusion on the surfaces to be adhered to the cathode sheet metal strip in the heat (at temperatures between 100 and 200 ° C., preferably 160 and 180 ° C. for 1 to 5 min), the sheets are cut to size and then brackets are welded to the narrow side surfaces of the cathode sheet, which connect the narrow side surfaces provided with an insulation strip.
  • the extrusion of the bar is carried out by co-extruding highly adhesive copolymeric polyolefin and normal polyolefin.
  • highly adhesive copolymeric polyolefin and normal polyolefin are advantageously used, as a result of which the cathode sheet metal according to the invention is produced becomes cheaper.
  • the heat required for the extrusion is optimally used.
  • the production can take place continuously, whereby large quantities of such cathode sheet metal strips can be produced. Afterwards, these can only be cut and the brackets required for the current introduction and suspension arranged on them.
  • cathode sheets in such a way that a layer of adhesive copolymeric polyolefin is arranged on the surfaces to be insulated and a part of ordinary polyolefin, which makes up the last body in its essential volume, is pushed onto this layer.
  • copolymeric polyolefins are copolymers of olefin and adhesive additives for metal surfaces.
  • These adhesive additives are usually aliphatic carboxylic acids in an amount of 1 to 10%, for example acrylic acid or its derivatives.
  • esters such as. B. vinyl acetates may be present.
  • Vinyl acetate can also be present at the same time as acrylic acid, as are other terpolymers.
  • those hot melt adhesives based on polyolefin are suitable which have sufficient corrosion resistance is guaranteed.
  • a cathode sheet with a plate 1 made of aluminum is arranged in an electrolyte 2 in a trough 3 on busbars 4, 4 'with its holder 5 and has insulation strips 6, 6' made of polyolefin fastened on both vertical narrow sides.
  • Fig. 2 shows an embodiment of the cathode sheet, in which on the side edge of the aluminum plate 1, a uniformly made of highly adhesive copolymeric polyolefin insulation strip is melted.
  • the insulation strip can be extruded and melted using the extrusion heat.
  • a layer 7 of adhesive copolymeric polyolefin is arranged on the aluminum plate 1 of the cathode sheet, and a U-shaped rail 8, which mainly forms the body of the insulation strip, is pushed over this.
  • the slide-on takes place in the heat, preferably using extrusion heat.
