Abstract:The actual production phenomenon of high current density zinc electrodeposition of 3.2 m2 large plate with complex high germanium material was analyzed. The influences of electrolyte clarity, impurity content in electrolyte, distribution of Pb in the electrolyte flow process, and current density on Pb content in zinc sheet Pb were studied. Based on the exploration and analysis, a series of measures were taken to reduce the lead content in zinc sheets, mainly from the aspects of inhibiting the dissolution rate of lead in anode plates and improving the settling effect of lead in electrolyte. The research and practice of zinc sheet Pb control technology can provide reference for the industry.
