Sodium carbonate (soda)

Capacity:320Thousand MT/a

M. F. :Na2Co3

M. W. :106

Property:Dense soda is a kind of white granular anhydrous compound; light soda is a kind of white powder or tiny crystal granular anhydrous compound. The product is easy solved in water and the solution is alkali. The product can absorb CO2 and water and give out heat in open air, and gradually changed into NaHCO3 and blocks.

Usage:The product is one of important chemical raw materials, and is widely used in chemical, metallurgy, national defense, weaving, dyeing, food, glass, enamel, medicine and paper industries.

Quality Standard:GB210.1-2004

Package:Plastic woven bag with inner plastic bag, 50kg net each for dense soda. Plastic woven bag with inner plastic bag, 40kg net each for light soda. Or container bag according to GB/T 10454, 1000kg net each.

Transport and Storage:北京赛车appThe product should be stored in shady, cool and drying place, prevent wetting and heating, should not be mixed sored and transported with acid. It's better to use container, pallet and have covering during transportation.
