Title:
METHOD FOR MANUFACTURING PERFORATED COPPER COIL FOR SHIELDED CATHODE PLATE
Document Type and Number:
WIPO Patent Application WO/2021/248848
Kind Code:
A1
Abstract:
A method for manufacturing perforated copper coil for a shielded cathode plate. The method comprises the following steps: imprinting a shielding point on a separator according to an expected distribution mode, attaching the separator to a cathode plate to be processed, and tearing off the separator after a material is formed to obtain the shielding point; adding a hot acid copper electrolyte to an electrolyzer, adding a prepared additive solution, turning on mechanical stirring, slowly stirring to keep the temperature in the electrolyzer uniform; mounting an anode plate and the shielded cathode plate in the electrolyzer, keeping the anode and cathode plates parallel, adjusting a stirring speed, turning on a constant-current rectifying machine, and timing; adjusting a current, and turning off the constant-current rectifying machine after timing is completed to obtain a cathode plate plated with copper foil; and performing passivation processing on the cathode plate plated with copper foil, cleaning, drying by blowing, and peeling off perforated copper coil from the cathode plate. According to the method, cation transmission of the shielding point is hindered, and naturally grown perforated copper foil is obtained, thereby avoiding cumbersome steps of later machining and the resulting mechanical property defects.
