摘　　要：研究了两性接枝共聚瓜尔胶作为助留剂应用于废纸浆的多种影响因素。结果表明:0.04%～0.08%的两性接枝共聚瓜尔胶(AC-GG)和0.8%的聚合氯化铝(PAC)配合使用,具有较好的助留效果,首程留着率比不加PAC的FPR高出55.51%,DDJ转速在1000r·min-1以内,共聚物维持较高的助留性能,共聚物受体系2000μs·cm-1以上高电导率的影响较小,适宜的pH在6～8。This article deals with the application of grafting copolymer of amphoteric guar gum as retention aid in waste-paper pulp, It is showed FPR increased by 55.51% as 0.04%-0.08% grafting copolymer of amphoteric guar gum and 0.8% dosage of PAC, compared with blank. As the DDJ less than 1 000r·min^-1, the better result can be obtained. Electrical conductivity has less effection to system above 2 000μs·cm^-1. And the better range of pH is 6-8 in this experimentation.
