Definitions

  • the present invention relates to a method and a device for producing a metal foil, the metal foil being electrolytically deposited on an endless carrier tape, preferably on an endless metal tape.
  • these foils in particular copper foils, are deposited electrolytically on drums. These drums are connected as a cathode and immerse approximately 40% of their circumference in an aqueous metal salt solution.
  • the anodes are located approximately 10 mm from the drum shell.
  • the metal is deposited on the drum by electrical current. The speed of the drum and the current set provide the desired film thickness, with approximately 20,000 to 25,000 amperes per drum being conventionally used.
  • the metal foil produced in this way is pulled off the drum, wound up and then aftertreated in a separate system.
  • the individual metal foils are connected to form an endless belt, transported through several galvanic cells and the desired metal or alloy layers applied.
  • the object of the present invention is to provide a method of the type mentioned at the outset which overcomes the disadvantages set out above and ensures inexpensive production of metal foils.
  • This object is achieved according to the invention in a method of the type mentioned at the outset by depositing the metal foil in one or more cells, the current density being set differently along the passage of the strip through the cell or cells.
  • the current density is also set differently along the passage of the carrier tape in each individual cell.
  • the endless metal strip runs through one or more vertical cells, each with two upper deflecting rollers and at least one lower deflecting roller, in which the film is built up on one side of the endless strip.
  • the individual cells are constructed in such a way that a closed shaft through which the electrolyte flows is formed by the endless carrier tape, the anodes and laterally provided sealing strips.
  • the deposition cells are characterized by several, at least three, current rollers in the area of at least one cell, the wrap angle being at least 2 °, and in that the anode follows the course of the carrier tape.
  • the electrolyte flows through the cells and the flow rate is 0.1 to 6.0 m / sec, preferably 1 to 4 m / sec.
  • This flow rate can be set as desired in this order of magnitude by means of an outlet with a variable cross section, which is provided essentially at the lowest-lying section of the anode.
  • the current rollers are connected to the anode individually or in any combination via rectifiers.
  • an endless carrier belt preferably runs through a plurality of vertical cells 2, which in the example shown are combined into two groups of 3 cells each.
  • a center control 3 ensures the precisely aligned passage of the belt 1.
  • the belt 1 Before entering the cells 2, the belt 1 is guided past brushes 4 via a vertically movable compensating roller 4.
  • the band 1, now coated with the metal foil is passed through at least one rinsing system 6 and one drying system 7.
  • the metal foil 8 is then pulled off the endless belt 1, advantageously trimmed and wound on the winder 9.
  • an electrolytic or purely chemical aftertreatment can be switched on in an aftertreatment system 10 with a connected dryer 11.
  • the aftertreatment of the metal foil can also be carried out at least partially on the carrier tape 1 before the foil is pulled off, so that only the aftertreatment has to be carried out on the side facing the endless belt after the foil has been cut off.
  • a circulation container for the electrolyte of the cells 2nd designated.
  • several containers 12 can also be provided, which is moreover absolutely necessary if different electrolyte liquids are used in the individual cells 2 or cell groups.
  • the electrolyte if necessary after reprocessing or cleaning, is returned to the separating cells 2 via circulation pumps (not shown).
  • the endless carrier tape 1 is cleaned mechanically, chemically or electrochemically after each pass in a conventional system (not shown).
  • the endless carrier belt 1 passes through a first upper deflection roller 21 to a lower deflection roller 22. From this lower deflection roller 22, the belt 1 is guided upwards again to a second upper deflection roller 21 '.
  • the upper deflection rollers 21, 21 ' can each be assigned to the two adjacent cells 2.
  • the belt 1 is guided in a direction deviating from the vertical, preferably approximately vertically.
  • the anode follows the course of the carrier strip 1 and forms on the lower deflection roller 22 opposite side of the strip 1 in cooperation with the strip itself and possibly sealing strips 24 between the latter and the anode 23, a channel through which the electrolyte flows and which is essentially at the lowest point of one Expiration 25 is limited with an adjustable cross section.
  • the latter can be used, for example, as a pipe socket a throttle valve and allows adjustment of the flow rate of the electrolyte liquid. This is introduced at the upper section of the anode 23 via a settling vessel 26, 26 'and the overflow 27, 27' into the channel between the belt 1 and the anode 23, with excess liquid being fed into an overflow vessel 28, 28 'and further directly to the circulation container 12 reached.
  • the electrolyte flowing through the cell 2 also enters the container 12 from the outlet 25.
  • the device there are two current rolls per cell.
  • the lower deflection roller 22 also takes on the function of a further current roller.
  • the variant which is preferably used provides, as shown in FIG. 2, exactly three current rollers per cell 2.
  • Two rollers 30, 30 ' are located in the upper region of the electrolyte channel and the third current roller is simultaneously the lower deflection roller 22.
  • the current rollers 30, 30' and 22, as well as any other current rollers, can be combined individually or in any groups with the Anode 23 may be connected, with at least one rectifier 31 being switched on in each connection.
  • the metal foil By controlling the current rolls or current roll groups with different current strengths, it is possible to deposit the metal foil on the endless carrier tape 1 along the tape 1 in the area of the cell 2, or more precisely along the anode 23 perform different current density values. Deposition at low current densities results in a homogeneous distribution of the particles, while high current densities result in a change in the grain size. Depending on the structural differences just mentioned, the mechanical properties of the deposited metal foil can also be influenced, for example.
  • the carrier tape 1 and the film on it are subjected to a rinsing with water before entering the next cell with different electrolyte.
  • the method according to the invention can also be used advantageously for the production of a composite material, in particular of metal composite films, one or more plants for film production being combined with unwinding devices for plastic strips in such a way that a composite material of film and plastic is produced.
  • a 17.5 ⁇ m thick copper foil made of an acidic copper sulfate electrolyte with various additives was produced in a foil plant with two cells, a 1200 mm wide carrier tape made of titanium and an anodes intended for carrying out the method according to the invention.
  • the current strength used was 80 A / dm 2
  • the electrolyte flow rate was 3.45 m / sec. After production, the film was rinsed on the carrier tape, dried and then easily removed.
  • the copper foil after drying and before being pulled off, was contacted with a plastic tape, which was coated on one side with adhesive, pressed and only then removed from the carrier tape.
  • the titanium carrier tape was replaced by a stainless steel tape stabilized from niobium and a 20 ⁇ m thick zinc foil was made from a zinc sulfate electrolyte in several cells arranged one behind the other, which after rinsing in a downstream cell was coated with a 5 ⁇ m thick zinc-nickel layer has been.
  • the current density for producing the zinc layer was 120 A / dm2 and the current density for producing the zinc-nickel layer was 65 A / dm2.
  • the test facility was expanded by two more cells and a new carrier tape made of copper, which was coated on all sides with titanium, was drawn in.
  • a new carrier tape made of copper which was coated on all sides with titanium, was drawn in.
  • titanium baskets filled with sintered iron pellets were then used instead of the insoluble anodes, while the insoluble anodes remained in the first and fourth cells.
  • the first and fourth cells were operated with a zinc electrolyte and the second and third cells with an iron electrolyte, thus producing an iron foil galvanized on both sides.
