Basic knowledge and application field of soda ash

Soda Ash, basic chemical raw materials, also known as alkali ash, soda, the composition of sodium carbonate, at room temperature for white odorless particles or powder, easily soluble in water and glycerin, per 100 grams of water can be dissolved 49.7 grams of sodium carbonate. The spot market usually divides soda ash into light soda ash and heavy soda ash, depending on its density. The density of light alkali is 500-600KG/m³, white crystalline powder; Heavy alkali has a density of 1000-1200 kg /m³ and is white in fine particles.

According to the different process, the upstream raw materials of soda mainly include raw salt, limestone, synthetic ammonia, etc., and the fuel mainly includes thermal coal, natural gas, etc. The downstream of soda mainly includes plate glass, photovoltaic glass, daily glass, paucine, baking soda, sodium, detergent and other industries. Among them, heavy alkali is mainly used in plate glass and photovoltaic glass field, light alkali downstream is more dispersed, generally used in daily glass, paohua alkali, baking soda, sodium, detergent, alumina, lithium carbonate, monosodium glutamate and other fields. Before 2021, the production capacity of flat glass and float glass are strictly controlled by the state, and the production capacity can only be replaced and cannot be added. In 2021, the replacement requirement of photovoltaic glass production capacity is cancelled, and photovoltaic glass production capacity is facing a big expansion, which brings a lot of new demand for soda ash and promotes the price rise of soda ash.
