[0002] Ion membrane caustic soda refers to caustic soda obtained by electrolyzing salt water using ion exchange membrane method, and its main component is sodium hydroxide. Ion membrane caustic soda has the advantages of high purity, low salt content, and low energy consumption, and is widely used in papermaking, textile, printing and dyeing, pharmaceutical, petrochemical and other industries. Salting is the upstream process of ion membrane caustic soda production, and its purpose is to dissolve the raw industrial salt and brine into saturated crude brine, and use physical and chemical methods to treat impurities in the brine to make refined brine that meets the requirements of ion membrane electrolyzers for use in electrolytic cells.
