摘要
本文研究了在同一淀粉分子链上,先后接上阳离子基团和阴离子基团的可能性,以及这种新型两性离子淀粉的各种性质,尤其着重研究在造纸工业作为助留剂的作用。结果发现,两性离子淀粉,比阴离子淀粉、阳离子淀粉都有较高的助留率,而与聚丙烯酰胺相类似,是一种较好的助留剂。
The various properties of amphoteric starch was investigated. The retention effect of the amphoteric starch as a retention agent in papermaking was paid attention to. It was found that the retention rate of amphoteric starch is higher than those of cation or anion starch, and is similar to polyacryamide. The amphoteric starch is a sood retention aeent.
