More Information
Summary:The invention discloses a copper foil production process which comprises the following steps: 1, manufacturing a raw foil: carrying out a reduction reaction on an electrolyte in an electrolytic bath to ensure that copper ions are precipitated on a surface of a cathode roller to generate the raw foil; 2, supplementing a liquid for the raw foil: supplementing a liquid for the upper surface of the raw foil passing through the lower part of the electrolyte through a liquid supplementing roller; 3, conducting surface smearing: flattening the newly-supplemented electrolyte on the surface of the raw foil through a scraping plate; 4, winding: winding the raw foil subjected to the steps by using a winding roller, and then carrying out subsequent procedures; and 5, conducting cathode roller polishing: polishing the cathode roller periodically through a polishing device. The equipment is provided with the liquid supplementing device and the smearing device, the stripped raw foil is subjected to follow-up treatment, so t
