  • the tenside used In addition to the legal approval for food use, also required are good wettability and adhesion of the paint used for coating with the tinplate surface post-treated with tenside, i.e., the tenside used must be tailored to the paints used. Due to the described application via spray tubes 11 , the formation of foam by the tensides that are used does not cause interference in the post-processing of the coated steel band.
  • the fluid streams striking the band surface were visible in the light of a lamp and one could see that the fluid pinched off by the pinching rollers 12 was distributed uniformly over the width of the pinching rollers 12 , detached in the form of droplets, and finally fell into the vertical tank 5 .
  • the tin-plated steel band samples treated in this way were then analyzed with a Leco C-analyzer at a maximum oven temperature of 400° C.
  • the tenside coating remaining on the tin-plated steel band surface after use of the method according to the invention is composed of the tenside deposit adsorbed onto the band surface, and the coating, which is produced from the thickness of the pinched fluid film and its tenside concentration.
  • the tinplate treated according to the method of the invention has significantly lower energy needs for drying in the drying device connected after the processing device.
  • the energy expense for drying the tinplate band can be reduced even more if the passivation fluid is heated in the passivation tanks 2 a , 2 b and/or the rinsing water is heated in the rinsing tanks 3 a , 3 b (for example, to temperatures of 50-70° C., the rinsing water also to temperatures up to 80° C.).
  • the adsorption time of the tenside solution sprayed onto the band surface according to the method of the invention is sufficiently short to guarantee a uniform adsorption of the tenside film onto the tinplate surface before the pinching rollers 12 pinch the excess tenside solution. Due to the short adsorption time, it is presumably not necessary to spray the fluid onto the tinplate surface as uniformly as possible via fine spray nozzles. Instead, it is sufficient-as provided according to the invention-to spray the tenside solution relatively coarsely onto the wet tinplate surface.
  • the advantage of spraying the tenside solution in the form of thin fluid streams distributed over the width of the steel band is that the risk of forming foam in the tank, in which the excess, especially the pinched tenside solution, collects is significantly lower than that when using spray tubes with nozzles, which would spray the tenside solution in a fine mist onto the tinplate surface.
  • the larger borehole diameters of the spray tubes tend to accumulate less foreign matter than do the smaller diameters of the spray nozzles required for the same application.
  • the tinplate bands examined in the comparison tests were examined with a three-ball tribometer in terms of their coefficient of sliding friction before and after the treatment according to the invention.
  • the tenside deposit does not reduce the sliding friction of the tin surface as much as does the DOS deposit. However, the sliding friction is good so that scratches and scrapes are not created on the tinplate surface when the tinplate rings break apart and the tables in the next post-processing stage can be cleared of packages without a problem.
  • the method according to the invention can also be applied in band tin-plating installations with horizontal rinsing cascades.
  • rinsing water is sprayed through spray registers with nozzles onto both band surfaces for each rinsing stage up to 40 m 3 /h.
  • the rinsing water is then pinched off and flows back into a storage tank under the corresponding rinsing stage, from where it is pumped back into the horizontal rinsing stage.
  • the method according to the invention can be used when the spray registers before the last pinching roller pair is replaced by the aforementioned tubes with boreholes, with which the aqueous tenside solution according to the invention is sprayed onto one or both band surfaces.
  • the tenside solution is sprayed first through a tube arranged above the top side of the band.
  • the aqueous tenside solution is sprayed onto the bottom side of the band, by spraying the tenside solution through a tube with boreholes on the pinching roller adjacent to the bottom side of the band.
  • the aqueous tenside solution is transported through the gap between the steel band and the pinching roller adjacent to the bottom side of the band, where the fluid mixes with the water film on the bottom side of the band and the band surface is “greased” in this way with the tenside film.
  • the pinched off tenside solution also flows back into a storage tank-as in the described embodiment of the band tin-plating installation with a vertical tank - and can then be reused.
  • the method according to the invention applied in the processing device 4 of the described band tin-plating installation can be used very generally for reducing the coefficient of friction of metal bands with a metallic coating, e.g., also special chromium-plated steel bands (ECCS).
  • ECCS chromium-plated steel bands
  • the samples were removed from the paint centrifuge and dried with hot air.
  • the painting adhesion was tested after the sterilization test through a cross-cut adhesion test and tesa test according to EN ISO 2409.
  • the tinplate samples greased with the various non-ionogenic tensides also had low organic deposits with ⁇ 5 mg/m 2 like tinplate samples greased electrostatically with dioctyl sebacate in a band tin-plating installation (desired deposit in the tinplate production at industrial scale: 4 ⁇ 2 mg/m 2 DOS).
