| 摘 要： | 研究聚乙烯胺(PVAm)在瓦楞原纸中对中性AKD施胶的促进作用以及对强度的影响。结果表明:当聚乙烯胺的加入量为0.1%时,手抄片的施胶度就已经优于加入1%阳离子淀粉的施胶度q,达到11.8s;加入量为0.3%(相对绝干浆)时,增强效果已与加入1%阳离子淀粉时相同,环压指数增加6%,裂断长增加8%;加入量为0.5%时,环压指数增加10%,裂断长增加17%。

| Abstract: | The paper studied that Polyvinylamine(PVAm) had the enhancing effect on sizing of AKD and the influence to the strength of the handsheets. It showed that when the dosage of the PVAm was 0.1% the degree of sizing was 11.8s, better than when the dosage of cationic starch was 1%; when the dosage of PVAm was 0.3%, the increment of strength was the same as when the dosage of the cationic starch was 1% too, the ring crush index(RTI) increased by 6%,the breaking length increased by 8%. When the dosage of PVAm was 0.5%, the RTI increased by 10%,the breaking length increased by 17%. |
