Function and Application:
Anhydrous sodium sulfite main use
1, sewage treatment: mainly used in electroplating wastewater, power plant sewage, chemical wastewater, domestic water and other solutions, and as a heating furnace power supply deoxidizer and dechlorination agent.
2, printing and dyeing industry: as a deoxidizing agent and bleaching solution, it is mainly used in the cooking of various knitted fabrics, which can avoid the harm of the chemical fiber of pure cotton fabric to the compressive strength of the chemical fiber, and improve the fineness of the cooking material.
3, chemical: do oxidizing and sulfonating agents, when in the organic chemical industry as m-phenyleneenamine, hydroxyl salicylate and other production of oxidizing agents, can avoid the reflection process of semi-finished product processing of air oxidation, in order to maintain oxygen sensitive raw materials; As a metal catalyst for the reaction of the formation of melamine formaldehyde resin; In the inorganic chemical plant, it is used to produce insurance powder, sodium pyrosulfite, sodium chlorite, cellulose sulfite ester, sodium thiosulfate, sodium bisulfite and so on.
4, paper industry: is to dissolve wood pulp in the lignocellulose, as a lignocellulose removal agent.
