摘　　要：通过正交试验分析,得到云南磷建筑石膏的pH值、细度、烘干时间是影响试验中有机硅活性的主要因素,并进一步得出pH值对试验中有机硅的活性影响最大,确定了pH值最佳范围。根据所得pH值,研究不同掺量的有机硅消泡剂对云南磷建筑石膏凝结时间、抗压强度的影响,并利用Origin软件进行试验数据拟合,后对拟合方程进行试验验证。According to the orthogonal test analysis,the p H value,fineness and drying time of Yunnan phosphorus building were the main factors affecting the activity of organic silicon. And further determined that p H value had the greatest influence on the activity of silicone in the experiment,and the optimum range of p H value were determined. According to the obtained p H value,the effect of different contents of organosilicon defoamer on the setting time and compressive strength of Yunnan plaster were studied. And the experimental data were fitted by Origin software,and the fitting equation was validated by experiment.
