摘　　要：通过分析离子膜烧碱电解过程中阳极产物反渗至阴极,与阴极产物氢氧化钠反应生成氯酸钠的3类原因,提出对应的贯穿于电解槽全过程的管理措施,从而达到降低离子膜烧碱生产过程中阴极液中的氯酸钠含量、提升产品的品质、减少氯酸钠对电解装置的危害的目的。Through the analysis of three kinds of reasons why the anode product permeates back to the cathode and reacts with the cathode product sodium hydroxide to produce sodium chlorate in the process of ionic membrane caustic soda electrolysis,the corresponding management measures throughout the whole process of the electrolytic cell are put forward.So as to reduce the content of sodium chlorate in the cathode liquid in the production process of ionic membrane caustic soda,improve the quality of products,and reduce the harm of sodium chlorate to the electrolytic device.
