The city has solid state and two kinds of liquid state to sell the caustic soda: The purely solid caustic soda is white, there are bulk , bar-shaped , granular, the quality is fragile ; The purely liquid caustic soda is the colourless transparent liquid. The solid caustic soda has very strong hygroscopicity. Apt to dissolve it in water, send out heat when dissolving, the aqueous solution is alkaline, there are soft senses ; Dissolve it in the ethanol and glycerin; Do not dissolve it in the acetone , ether . Corrosivity is extremely strong, have function of corroding on fibre , skin , glass , pottery ,etc..Main uses: the manufacture of chemicals, paper, aluminum smelting, refining tungsten, artificial silk, rayon and soap manufacturing, production of dyes, plastics, pharmaceutical and organic intermediates, the old rubber recycling, metal sodium, water electrolysis as well as the inorganic salt production, Preparation of borax, chromium salts, manganese salts, phosphate, etc. need to use a lot of caustic soda Packing:Flakes or pearls: 25kg plastic bags(3layer pp&pe)
