摘　　要：从原料来源、制备方法和用途等方面概述了工业用盐的品种及其生产方法,探讨了卤水用于离子膜法制碱生产中存在的水不平衡、卤水含氨(胺)等问题。认为真空盐用于离子膜法制碱生产具有确保制碱盐水的质量、节约精制剂、有利于环境保护及节约建设投资和生产费用等优势,并经详细计算,其直接经济效益为371.7万元 a。The varieties and production methodes of industrial salts are related from the aspects of material sources,production methodes and applications.The problems including water unbalance and amine-containing bittern,which exist in ion-exchange caustic soda production by using bitern,are discussed.It is analysed that vaccum salt applying in the caustic soda production can certainly insure the quality of brine,save refiners,be profitable to environmental protection,and save construction investment and production costs.It is obtained by detail calculation that the direct economic benefit is 3 717 000 Yuan(RMB)/a.
