Storage of  sodium sulfite Fabric bleaching agent

 Sodium sulfite should be stored in a dry and cool place.

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.
