Caustic soda (NaOH) has a wide range of uses. Used in the production of paper, soap, dyes, rayon, smelting metals, petroleum refining, cotton fabric finishing, purification of coal tar products, and food processing, wood processing and machinery industry.
The most used sodium hydroxide is the manufacture of chemicals, followed by paper making, aluminum smelting, tungsten smelting, rayon, rayon and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, old rubber regeneration, metal sodium, the electrolysis of water and inorganic salt production, preparation of borax, chromium salt, manganese salt, phosphate, also want to use a lot of caustic soda. At the same time, sodium hydroxide is one of the important raw materials for producing polycarbonates, super absorbent polymers, zeolites, epoxy resins, sodium phosphate, sodium sulfite and a large amount of sodium salt.
