本文探讨用贵县三水铝石制取工业和环保急需的碱式氯化铝。并从工艺条件、设备、生产成本、产品分析结果和净水效果等方面与以平果—水硬铝石、福建粘土矿为原料生产氯化铝进行了比较。结果表明,贵县三水铝石为生产碱式氯化铝的较佳原料。 This article discusses the use of Guizhou gibbsite prepared from industrial and environmental protection is much needed basic aluminum chloride. And the production conditions of aluminum chloride were compared with those of Pingguo - diaspore and Fujian clay mine from the aspects of process conditions, equipment, production cost, product analysis results and water purification effect. The results show that Guixian gibbsite is the preferred raw material for the production of basic aluminum chloride.
