Sodium Chloride Tech Grade / Industry Salt Powder / Granule

Oct 24, 2017


Sodium chloride, chemical formula NaCl, colorless cubic crystal or fine crystalline powder, taste salty. Appearance is white crystal, the source is mainly seawater, is the main ingredient of salt. Soluble in water, glycerol, slightly soluble in ethanol (alcohol), liquid ammonia; insoluble in concentrated hydrochloric acid. Impure sodium chloride has deliquescence in the air. Stability is better, the aqueous solution was neutral, the industry generally use electrolysis of saturated sodium chloride solution to produce hydrogen, chlorine and caustic soda (sodium hydroxide) and other chemical products (commonly known as chlor-alkali industry) also Can be used for ore smelting (electrolytic melting of sodium chloride crystal production of active sodium), medical for the allocation of saline, life can be used for condiments.

1, Electrolytic sodium chloride solution, will produce hydrogen and chlorine, chlorine in the chemical industry has a wide range of applications, can be used for the synthesis of polyvinyl chloride, pesticides, hydrochloric acid and so on.
2, When the law made of metal sodium: electrolytic melting of sodium chloride and calcium chloride mixture of sodium. Calcium chloride used as a flux, the sodium chloride can be reduced to below 700 oC melting point. Calcium reduction is less than sodium, not the introduction of impurities.
3, Iodium chloride is necessary for many biological reactions, such as molecular biology experiments in a variety of solution formulations contain sodium chloride, bacterial culture medium contains sodium chloride. At the same time, it is also a raw material for soda ash.
4, Inorganic and organic industries for the manufacture of caustic soda, chlorate, hypochlorite, bleach powder raw materials, refrigeration system refrigerant, organic synthesis of raw materials and salting out pharmaceutical. Iron and steel industry for heat treatment agent. High temperature heat source and potassium chloride, barium chloride and other dosing salt bath, can be used as heating medium, so that the temperature maintained at 820 ~ 960 oC between. In addition, it is also used in glass, dyes, metallurgy and other industries.
5, The aqueous solution can be used for selection. The NaCl solution is configured according to the species needs, and its density is larger than that of water. Seeds into the NaCl solution, floating is not full, sink full.
