摘要
国内烧碱主要用于轻工业、化工、纺织和医药等 ,生产方法以隔膜法和离子膜法为主。详细介绍了盐水精制工艺、淡盐水脱氯工艺及电解槽发展情况、膜法工艺。离子膜法生产技术是目前世界上最先进、最节能和最节省投资的方法 ,但中国尚不能生产离子膜 ,导致国内离子膜烧碱生产并不经济 ,中国应尽快将离子膜国产化 。
Caustic soda is mainly used in the fields of light industry,chemical industry,textile industry,medical industry,etc.,and is produced mainly by diaphragm process and ion exchange membrane process at home.In this paper,the technologies of brine purification,chlorine removing of dilute brine are introduced in detail.The production of caustic soda by ion exchange membrane process is the most advanced,energy-economical and money-saving technology currently worldwide.However,domestic caustic soda production by ion exchange membrane process is not economical,which results from that domestic enterprises still have no ability to produce ion exchange membrane.The manufacture of ion exchange membrane in China should be realized as soon as possible in order to promote and benefit the development of domestic chlor-alkali industry.
