摘　　要：介绍了AK糖石膏的产生过程,通过对比不同预处理方法对AK糖石膏中有机物的去除及对其制备的建筑石膏性能的影响,确定最佳预处理工艺,并在此基础上对AK糖石膏的煅烧制度进行了研究。结果表明,水洗预处理对AK糖石膏中的有机物有良好的去除效果并且较好地改善了糖石膏性能,煅烧温度及保温时间对AK糖石膏净浆的物理力学性能有较大的影响,确定煅烧阶段工艺参数为:煅烧温度190℃,保温时间3 h。The produce process of Acesulfame-K gypsum is introduced,through comparing the different pretreatments on the removal of organic matter and the influence on the performance of the building plaster, the optimal pretreatment process is con- firmed. On that basis study is also made on calcining process of Acesulfame-K gypsum. The result shows that washing pretreat- ment process hasa good effect on the removal of organic matter and improve the performance of Acesulfame-K gypsum .largely. Calcining temperature and time have great influence on the mechanical property of Acesulfame-K gypsum. The parameters of cal- cining stage are confirmed that the calcining temperature is 190℃ and the holding time is 3 h.
