The glass industry is the largest consumption sector of soda ash, consuming 0.2 tons of soda ash per ton of glass.
1.Glass : the glass industry is a large consumer sector of soda ash.soda consumption per ton of glass is 0.2T.
2. Detergent : It is used as detergent in wool rinsing,medicine and tanning.
3. Printing and dyeing : printing and dyeing industry is used as a water softener.
4. Buffer :as buffering agent,neutralize and dough improver,it can be used for pastry and noodle food,and can be used
appropriately according to production needs.
It is strongly alkaline and corrosive. It can be used as acid neutralizer, matching masking agent, precipitating agent, precipitation masking agent, color developer, saponification agent, stripping agent, detergent, etc. With strong alkaline and strong hygroscopicity. Easily soluble in water, exothermic when dissolving. The aqueous solution is alkaline and greasy. It is highly corrosive and is corrosive to fibers, skin, glass and ceramics. It reacts with aluminum, zinc, non-metallic boron, and silicon to
release hydrogen, and undergoes disproportionation reaction with halogens such as chlorine, bromine, and iodine, and neutralizes with acid to generate salt and water.
