摘　　要：用CS(阳离子淀粉)、PEI(改性聚乙烯亚胺)和CPAM(阳离子聚丙烯酰胺)等对麦草浆的助留、助滤作用进行了研究,结果表明,CS、CPAM、PEI对麦草浆来说,都是良好的助留剂,从达到细料留着效果所需的用量来看,CPAM<PEI<CS。从淀粉种源看,马铃薯淀粉对细料的留着效果最好,其次是木薯淀粉,再次为玉米淀粉,取代度高的阳离子淀粉对细料的留着效果比取代度低的阳离子淀粉好。CS、CPAM、PEI对麦草浆的助滤作用明显,但必须在适量范围内。Effects of modified starch?PEI and CPAM on retention and drainage of bleached chemical wheat-straw pulp is studied in this paper.They improve in fines reten tion as well as drainage.The fines retention and drainge of the wheat straw pulp can be improved by us-ing these aids.The high DS cationic starch is more effective than the low one,and the modified potato starch has better retention effect than corn starch and tapioca starch.
