硅渣制九水偏硅酸钠工艺研究

Discussion on the technology of Na_2SiO_3·9H_2O

九水偏硅酸钠作为碱水剂广泛用于陶瓷工业生产中。通过利用冰晶石生产过程中产生硅渣与片碱生产九水偏硅酸钠和天然石英石与液碱生产九水偏硅酸钠的两种生产工艺进行研究和对比,指出用工业硅渣代替石英石生产九水偏硅酸钠具有成本和环保优势。

Na2SiO3·9H2O is widely used in the production of ceramic industry as a alkali water agent.The research and comparison of two kinds of production process to produce silicon slag and caustic soda production nine water sodium metasilicate and natural quartz and Na2SiO3·9H2O through the use of caustic soda production of cryolite production process,pointed out that the industrial silicon slag instead of quartz stone production Na2SiO3·9H2O has cost and environmental advantages.
