| 摘 要： | 作为废纸回用的涂布纸中含有多种聚合物，它们形成白色树脂。改良型阳离子聚乙烯亚胺由于是伯仲叔三种胺基的高度支链化的化合物，起到树脂固定剂的作用。靠残留的高电荷阳离子把它强力的固定在纤维上，使白树脂与纸张一起离开纸机。

| Abstract: | Various polymers are contained in the reclaimed coated paper and the white pitch depositions formed wherefrom have unfavorable effect on the operation of paper machine and on the quality of paper. The improved cationic polyethyleneimine, which is a highly chainbranched compound from primary, secondary and tertiary amidogen, can be used as pitch anchoring agent which fixed pitch onto fiber by the remnant high charge cationic and brought the pitch out of the paper machine system. |
