JINGSHEN Soda ash Dense Sodium Carbonate
Product Introduction
Heavy soda ash is made of light soda ash under certain temperature conditions, hydration reaction with water to produce sodium carbonate monohydrate. Compared with anhydrous sodium carbonate, sodium carbonate monohydrate has dense and smooth crystal, large and uniform crystal particles. After heating and dehydration, the crystal still maintains the original characteristics, and the density of the pile is twice that of light soda ash, and the packaging, storage, transportation are more economical than light soda ash. Heavy soda ash is mainly used in glass, metallurgy and pigment industries, and in packaging, storage, transportation than light soda ash economic.
