Superiority:

we are professional manufacturer in inorganic and organic chemical product sodium sulfite anhydrous with puriity 96%-98%,with a land area of 13000 square meters.Now our full annually production is above 80000 tons.

We have experienced technicians, leading facilities, a modern management system and an excellent after-sale service system. We use the Mechanical Vapor Recompression technology for production and Automachine for package. Our products is chean and pure,the quality is over food grade standyard. Output of sodium sulfite anhydrous covers over 18 provinces in china market.

Details:

We use experienced technology for production. First,extract the chean gas of sulfur dioxide from the production part of sulfuric acid, Mixture with food grade sodium carbonate,it comes out high quality sodium hydrogen sulfite. Second,after chemical treatment of sodium hydrogen sulfite ,mixture with ionic membrane sodium hydroxide, generated sodium sulfite with water. After concentration, desiccation and crystallization,it comes out sodium sulfite anhydrous,then we packed up the products into the warehouse.
