介绍了离子膜电解装置中离子膜的经济使用寿命,分析计算了更换离子膜的最佳时机。合理确定离子膜换膜时间,有利于离子膜制碱能源利用效率的提高,降低生产成本。%Introduced the economic life of the ion-exchange membrane in manufacture of ion-exchange membrane alkaline. Analyzed and calculated the best time to be replaced ion-exchange membrane in our company. The drop in market price of ion-exchange membrane causes changing ion-exchange membrane time ahead of time, improves energy utilization efficiency in manufacture of ion-exchange membrane caustic soda and reduces the production costs.
