摘要
聚胺－聚酰胺－环氧氯丙烷是一种造纸用湿强剂，为提高它的增强效果，我们采用淀粉黄原酸钠作为助留剂，实验证明这样做可大幅度降低助剂用量，增强效果却明显提高．
The polyamide-polyamine-epichlorohydrin is one of the wet strengthagellts for papermaking. In order to increase its strength effect we use sodium starchxanthate as vetention aid. The experiment demonstrates that in this way the amount of as-sistant can be reduced very much and the effect of the assislant can be improvedconsideralbly.
