5.Chemical properties: Strong stability, but also can be decomposed at high temperature to produce sodium oxide and carbon dioxide. Strong moisture absorption, it is easy to form a lump, do not decompose at high temperatures.
6.Solubility: soluble in water, slightly soluble in ethanol, insoluble in alcohol.
7.Appearance: White powder, is a solid
8.Transport or Storage:
Transportation: To complete the time of shipment packing, loading should be conservative. Transportation process to ensure that the container does not leak, did not fall, not fall, no damage. Strictly prohibited and acids, food chemicals, etc. mixed mixed transportation. Transportation should prevent exposure, rain, antihigh temperature. Transport vehicles should be completely finished cleaning.
Storage: Store in a cool, ventilated warehouse. Away from fire and heat. Acids, etc. should be kept separate, should not mix storage. Storage areas should be equipped with suitable host material spill.
9.Usage: One is an important chemical raw material used in making chemicals, cleaning agents, detergents, and the system is also used for photography pharmaceuticals.
Most are used in industry, a small portion of the civilian. In the industrial soda ash, mainly light industry, building materials, chemical industry, accounting for about 2 / 3; followed by metallurgical, textile, petroleum, national defense, medicine and other industries. Soda glass industry is the largest consumer sector. Chemical industry for manufacturing sodium silicate, sodium dichromate, sodium nitrate, sodium fluoride, baking soda, borax, trisodium phosphate, etc.. Flux for smelting metallurgical industry, mineral flotation agent used, steel and antimony used as a desulfurization agent. Printing and dyeing industry as a water softener. Leather tanning industry for the degreasing of raw materials, and in chrometanned leather and tanning liquid caustic soda increased degree. Also for the production of synthetic detergent additive sodium tripolyphosphate and other sodium salt. For the production of soda ash food grade MSG, pasta, etc.
10.Production process: With salt, ammonia, carbon dioxide as raw material, at room temperature for precipitation of sodium bicarbonate from the solution, heating it, that is decomposed into sodium carbonate.
