| titleOfInvention | A kind of roughening treatment Processes and apparatus for Pb-free coating electrolytic copper foil |
| abstract | The invention discloses a kind of roughening treatment technique for Pb-free coating electrolytic copper foil, the combined additive of at least three kinds of compounds composition in sodium tungstate, sodium molybdate, sodium nitrite, stannous sulfate, hydrochloric acid, cerous sulfate, ceric sulfate is used in treatment process；The combined additive instead of high toxicity additive arsenic use, it is therefore prevented that the harm to environment and human body；Also, the node that the combined additive can make some row on copper foil isolated forms loose knurl, and with more the rough surface of height expansion, the permeability and adhesive force between base material are stronger, and appearance coloration is more uniform.In addition, equipment used by the invention discloses treatment process, roughening slot including being used to hold roughening treatment liquid, be fixedly connected multiple rollers for being used to transmit copper foil in the roughening slot, the roller is arranged at intervals above and below, so that the copper foil is centered around the periphery and forms wavy shape, it can extend or shorten according to actual needs time of the copper foil in roughening treatment liquid. |
