【摘要】 研究了阳离子淀粉、阳离子接枝淀粉和两性淀粉的助留作用。分别添加 1%的两性淀粉、0 0 5 %的阳离子接枝淀粉和 1%阳离子淀粉 ,漂白麦草浆的填料留着率分别提高了 2 3 8、2 2 6和 14 2个百分点 ,表明阳离子接枝淀粉和两性淀粉是优于阳离子淀粉的优良助留剂。更多还原

【Abstract】 In this paper, cationic starch, cationic graft corn starch(CGS) and amphoteric starches were used as filler retention aids. Filler retention respectively in bleached wheat straw pulp increased 23.8%, 22.6% and 14.2% by adding 1% amphoteric starches LS L2 2,0.05% cationic graft corn starch(CGS) and 1% cationic starch (ZJ 4). The results showed that as filler retention aids cationic graft corn starch (CGS) and amphoteric starches were superior to cationic starch.更多还原
