一、试验情况金川公司镍电解车间为了对镍电解车间实行“挖潜、革新、改造”,进行了高电流密度、高pH值的试验。自1979年8月开始,至81年上半年止,冶炼厂坚持了由小到大的工业规模试验,即将141～162安培/米~2提高到190～223安培/米~2,pH值由2.8～3.0提高到4.5～5.5,温度由55～ First, the test situation Jinchuan nickel electrolytic plant in order to implement the nickel electrolytic plant “to tap potential, innovation, transformation,” conducted a high current density, high pH test. Starting from August 1979 until the first half of 81, the smelter insisted on an industrial scale test from small to large, that is, it increased the temperature from 141 to 162 Amperes / m 2 to 190 to 223 Amperes / m 2, 2.8 ~ 3.0 increased to 4.5 ~ 5.5, the temperature from 55 ~
