【摘要】 采用磷石膏制备β-半水石膏粉,对磷石膏粉煅烧温度、升温速度、煅烧时间、研磨条件、陈化时间等工艺条件进行了系统研究,获得了用磷石膏生产优等建筑石膏的工艺条件,为加快开发利用磷石膏资源奠定了基础。更多还原

【Abstract】 The tests of preparing β-CaSO4·1/2H2O with phosphogypsum was carried out. The process conditions such as calcinations temperature, speed of raising temperature, calcinations time; grinding condition, aging time and so on were researched systematically. The process conditions of producing high class building gypsum with phosphogypsum were obtained from the tests. The foundation of accelerating the development of phosphogypsum resources was established.更多还原
