摘要
铝土矿粉+硫酸为原料,菱镁石矿粉为碱化剂,硫化钠或螯合剂为重金属沉淀剂。铝土矿粉在加压反应釜通过微碱化度生产工艺,与一定量的硫酸发生酸溶-水解-碱式化-桥连聚合反应,分三步生产聚合碱式硫酸铝多元盐净水剂。
Bauxite powder+sulfuric acid as raw material,magnesite powder as alkalizing agent,sodium sulfide and chelating agent as heavy metal precipitating agent,bauxite powder undergoes acid dissolution-hydrolysis-basification-bridging polymerization reaction with a certain amount of sulfuric acid in a pressurized reaction kettle through a micro-basicity production process to produce a polymeric basic aluminum sulfate multi-component salt water purifier in three steps.
