在铅银合金中加入一定量的混合稀土,制成锌电积的阳极,以直接对比的方法进行试验,结果表明:混合稀土-铅-银合金可以提高阳极的寿命和强度.提高析出锌的质量,节约电能,经济效益显著.
A certain amount of mixed rare earth was added into the lead-silver alloy to make the positive electrode of zinc electrowinning. The direct-contrast test was conducted. The results showed that the mixed rare earth-lead-silver alloy can improve the life and strength of the anode. Quality, energy conservation, significant economic benefits.
