摘要
研究了改性磷石膏生产建筑砖的工艺最佳物料配比。通过复合胶凝材料对磷石膏低温陶瓷化,首先由正交试验得到复合胶凝材料中最优DSZ:FMH:KZ为1:1:1,然后得到了最优磷石膏:复合胶凝材料为1:1,最后在固定磷石膏50%的前提下,由单因素试验优化得到DSZ、FMH、KZ的最佳掺量分别为12%、18%、20%,最佳养护时间是20h。
The optimal proportion in the process of producing building brick from modified phosphogypsum was studied.Through the low-temperature ceramics modification of phosphogypsum using composite cementitious material,the optimal proportion for DSZ：FMH：KZ is obtained to be 1：1：1 with orthogonal experiments firstly.Then the best ratio of phosphogypsum to composite cementitious material is 1：1.Lastly with the constant phosphogypsum content of 50%,the best content of DSZ,FMH and KZ is 12%,18% and 20% respectively and the best curing time is 20 h through single factor experiments.
