Soda ash light is a white powder or fine-grained crystal anhydrous, easily soluble in water, can absorb CO2 and water when exposed to the air at room temperature, and release heat, gradually turn into NAHCO3 and agglomerate.
Soda ash light is one of the important basic chemical raw materials. It is widely used in chemical industry, metallurgy, national defense, textile, printing and dyeing, food, glass, enamel, paper and other fields

1. Ammonia alkali method (also known as Solvay method)
2. Combined alkali production method (also known as Hou's alkali production method) uses salt (sodium chloride), limestone (calcined to generate quicklime and carbon dioxide), and ammonia gas as raw materials to produce soda ash. First, ammonia gas is passed into saturated brine to form ammonia brine, and then carbon dioxide is passed into it to generate sodium bicarbonate precipitation and ammonium chloride solution with low solubility. The NaHCO3 fine crystals obtained by filtration and washing are heated and calcined to obtain soda ash products.
