【Abstract】 A functional coagulative agent containing C[ZJZ;Y;LX,YS] NH 2 O,C[ZJZ;Y;LX,YS] OH O,and —SO 3H groups was obtained by reaction of taurine with polyacrylamide in the microwave’s field. It could reduce η r (relative viscosity) by 7 5% and η sp (increase ratio viscosity) by 12 5% on 27% P 2O 5 wet process phosphoric acid,and change the gypsum crystal form so that the filtrution speed increased by 22% on the separation of gypsum and phosphoric acid.更多还原
