造纸增强剂聚丙烯酰胺
阳离子酰胺作为纸张增强剂,阳离子酰胺的酰胺基纤维的羟基在纤维之间形成氢键结合,增强纤维之间的结合力,达到增加纸张的强度的目的,阳离子pam还可以作为湿强剂,增加纸张的湿强度,来抵抗水对纸张的破坏。
阴离子酰胺pam是造纸厂常用的造纸助剂,高分子量的阴离子PAM被用作絮凝剂,用来絮凝处理造纸厂所产生的废水,还被作为悬浮剂和润滑剂用在长纤维浆料纸张当中,增加浆水的黏稠度,起到水溶性润滑剂的作用,使纤维不缠结在一起,改善了纤维之间的絮聚情况,提高了纤维的交织能力,同时也增强了纤维在介质中的悬浮性,延长了沉降的时间。
低分子量的阴离子聚丙烯酰胺则被用作分散剂,起到减缓纤维的絮凝和沉降的作用,使得纤维能均匀的在水中分布,极大的改善上网浆料的匀度,从而能够的较低的打浆度、较长纤维的情况下抄造出较薄的、高质量的纸张。

Paper reinforcer
Cationic amide is used as paper reinforcer. Hydroxyl groups of amide-based fibers of cationic amide form hydrogen bonds between fibers to enhance the bonding force between fibers, so as to increase the strength of paper. Cationic PAM can also be used as a wet strength agent to increase the wet strength of paper to resist the damage of water to paper.
Anionic amide PAM is a commonly used paper-making additive in paper mills. Anionic PAM with high molecular weight is used as flocculant to flocculate wastewater from paper mills. It is also used as suspension agent and lubricant in paper with long fibre pulp to increase the consistency of pulp water and play the role of water-soluble lubricant, so that fibers are not tangled together and flocculation between fibers is improved. It improves the interweaving ability of the fibers, enhances the suspension of the fibers in the medium, and prolongs the settling time.
Low molecular weight anionic polyacrylamide is used as dispersant, which can slow down the flocculation and sedimentation of fibers, make the fibers evenly distributed in water, and greatly improve the uniformity of surfing slurry, so that thin and high-quality paper can be produced with lower beating degree and longer fibers.
