两性高分子聚丙烯酰胺助留助滤剂在非木材纤维中的应用效果

Application Effect of Macromolecule Amphoteric Polyacrylamide Used as Retention and Drainage Aids in Nonwood Fiber

在非木材草类纤维中加入两性高分子聚丙烯酰胺助留、助滤剂,对其效果进行了探索。实验结果表明:用量在1%时,其助滤、助留的效果最好。但高分子的聚丙烯酰胺的助滤效果远不及助留效果好。

The effect of macromolecule amphoteric polyacryamide used as retention and drainage aids in nonwood fiber is studied. The results showed that when the dosage of macromolecule amphoteric polyacryamide was 1%, it had the best effect on retention and drainage. But the macromolecule amphoteric polyacryamide effecting on the drainage was much worse than that on retention.
