摘　　要：陕西金泰氯碱化工有限公司旭化成电解槽换离子膜后电解槽电压上升,吨碱电耗增加,电流效率下降。从二次盐水品质、进槽盐酸控制、停车次数及离子膜本身的老化、单元槽和离子膜运行时间等角度,分析了槽电压上升、电流效率下降的原因,为电解槽系统改造提供了有力的证据。After Shaanxi Jintai Chlor exchange membranes for Asahi Kasei ion -Alkali Chemical Industry Co., Ltd. changed the ion -exchange membrane electrolyzers, the cell voltage increased the unit electricity consumption for production of caustic soda increased, and the current efficiency decreased. The causes were analyzed in terms of the quality of secondary brine, the control of hydrochloric acid fed into electrolyzers, shutdown times, the aging of ion - exchange membranes, and the running time of unit cells and ion - exchange membranes. Thus, better evidence was provided for the transform of electrolyzer system.
