摘要
概述了天然石膏、脱硫石膏、磷石膏3种石膏的来源,从物化特征、杂质特征、分布特征等方面对3种石膏做了详细的对比分析。结果表明,不是所有天然石膏的品质都优于工业副产石膏,一些脱硫石膏或磷石膏的纯度会高于天然石膏。简述了β-半水石膏、α-半水石膏、石膏晶须的生产与现状。提出了要大力开发工业副产石膏的应用,仍有诸多问题需要解决。
The sources of natural gypsum,flue gas desulfurization gypsum,and phosphogypsum were summarized,and three kinds of gypsums were analyzed in detail from the aspects of physical and chemical characteristics,impurity characteristics,and distribution characteristics.It was concluded that not all natural gypsums′ quality was superior to industrial by-product gypsum,some desulfurization gypsum or phosphogypsum′s purity will be higher than that of the natural gypsum.The production and status of β-hemihydrate gypsum,α-hemihydrate gypsum,and gypsum whisker were briefly described.It suggested that if the application of industrial by-product gypsum is vigorously developed,there are still many problems to be solved.
