Character:

Single product is colorless transparent crystal, relative density 2.130.The melting temperature of 318.4 ℃.The boiling point of 1390 ℃.Caustic soda market is a solid and liquid two: pure white solid caustic soda, blocks, sheet, rod, granular, very brittle.The pure liquid caustic soda is colorless transparent liquid.Solid caustic soda has strong hygroscopicity.Soluble in water, dissolve the exothermic, alkaline aqueous solution, soapy;Soluble in alcohol and glycerin;Not soluble in acetone, ethyl ether.Strong causticity, of the fibers, the skin has corrosion effect, glass, ceramics and so on.With metal reactions such as aluminum and zinc, boron and silicon, not release hydrogen;With chlorine, bromine, iodine, halogen disproportionation reaction;And acid neutralization and form a salt and water.

Usage:

1. Used for paper making, cellulose pulp production.

2. Used in soap, synthetic detergent, synthetic fatty acid production and refining of vegetable oils or animal fat.

3. Used for cotton textile printing and dyeing industry desizing agent, scouring agent and SiGuangJi.

4. Chemical industry for the production of borax, sodium cyanide, oxalic acid, phenol, etc.

5. The oil industry for refining petroleum products, and used in oil field drilling mud.Also used in the production of alumina, metal surface treatment of zinc and copper and glass, enamel, leather and pesticide, medicine, dye.

6. Food grade products in the food industry used as acid neutralizer, can make peeling agent of citrus, peach and so on, also can be used as detergent bottles, cans and other containers, and decoloring agent, sweetening agent.

7. Can also be used to do basic desiccant.Caustic soda is widely applied in the national economy, many industrial department need caustic soda.Using caustic soda most departments are the manufacture of chemicals, followed by paper, aluminium, tungsten smelting, rayon, viscose and soap manufacturing.In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, old rubber regeneration, sodium metal, the electrolysis of water and inorganic salt production, producing borax, chromium salt, manganese acid salt, phosphate, etc., also want to use a large amount of caustic soda.
