    • PURPOSE: A method for efficiently manufacturing electric lead is provided to recover the high purity of lead with the extremely low bismuth level from a lead anode with high bismuth level without investing equipment. CONSTITUTION: A method for manufacturing electric lead comprises the following steps of: producing an anode by adjusting the concentration of antimony to be 1 to 3 mass% with respect to the lead row material with 5 to 30 mass% of bismuth concentration; performing an electrolytic process in the electrolytic cell by using the anode; drying the lead electrolytic deposit remained on the surface without exfoliating and detaching from the anode surface during the electrolytic process by extracting the anode from the electrolytic cell; and removing the dried lead electrolytic deposit from the anode.
    • 目的:提供一种高效制造电铅的方法,从具有高铋水平的铅阳极的铋水平极低回收铅的高纯度,无需投资设备。 构成:电铅制造方法包括以下步骤:通过以相对于引线列材料调整锑浓度为1〜3质量%的铋浓度为5〜30质量%来制造阳极; 通过使用阳极在电解池中进行电解处理; 在电解过程中,通过从电解池中提取阳极,使铅电解沉积物残留在表面上而不会从阳极表面剥离和脱离; 并从阳极去除干燥的铅电解沉积物。

    • PURPOSE: An electrolytic method of lead is provided to collect smooth electro deposited lead without installing fluorine removal facility. CONSTITUTION: An electrolytic method of lead comprises the following steps: adding 10mg/L of Noigen (trademark : registered trademark) BN-1390 as a leveling agent to a solution which is adjusted as 80g/L of lead concentration and 20g/L of sulfamic acid concentration; charging the same into an electrolyzer by using high Bi lead as an anode and an end plate of lead or a stainless plate as a cathode; supplementing electrolyte in an electrolyzer after electrode charging and supplying so that the electrolyte can stay in the electrolyzer for 1 hour; and collecting smooth electro deposited lead by applying electric current as electric current density of 100A/m^2 after adjusting the temperature of the electrolyte as 20-30 °C.
