Product description:Single product is colorless transparent liquid. Relative density 2.130, melting point is 318.4 ℃, boiling point of 1390 ℃. Caustic soda market is a solid and liquid two: pure white solid caustic soda, flake, massive, granular and rod, very brittle. The pure liquid caustic soda is called liquid alkali, colorless transparent liquid. Impurities in industrial goods more, mainly as sodium chloride and sodium carbonate, etc., and sometimes a small amount of iron oxide. When dissolved into thick liquid alkali, most of the impurities floats on liquid surface, can be separated. Solid caustic soda has a strong hygroscopicity, soluble in water, dissolve the exothermic, into a strong alkaline solution, have a creamy touch and bitter taste, can make the blue litmus paper red atmosphere, make the red phenolphthalein solution.Important basic chemical raw materials, a wide use. The chemical industry used in the manufacture of formic acid, oxalic acid, borax, synthetic fatty acid, phenol, sodium cyanide and soap, synthetic detergent, etc. Textile printing and dyeing industry used as cotton desizing agent, scouring agent, SiGuangJi VAT dye, hydron blue dyes and solvents. Smelting industrial manufacture of aluminum hydroxide, alumina and metal surface treatment agent. Instrument industry used as acid neutralizer, decoloring agent, sweetening agent. Adhesive industry is used as the starch pasting agent, neutralization agent. In addition, in enamel, medicine, cosmetics, leather, coatings, pesticides, glass and other industries have a wide range of applications.
