摘　　要：考察了聚胺的结构对零排放箱纸板造纸系统中AKD施胶效果的影响。结果表明:高阳电荷密度的聚胺可大幅提高AKD施胶度,聚胺的阳电荷密度决定其作用,而其相对分子质量的影响较小;使用聚胺/淀粉复合物可减少聚胺用量,降低助剂使用成本;聚胺对AKD施胶的作用主要是减小浆料中的阴离子垃圾含量,增加微细纤维等的留着。Effects of structures of the polyamines on AKD sizing in the zero discharge system for making cardboard were investigated.The results show that the polyamines with high cationic charge density can greatly improve AKD sizing degrees in the system.The cationic charge density of the polyamines plays a key role in the sizing,but the effect of their molecular weights is relatively small.The use of the polyamide /starch complex can decrease the amount of the polyamines and reduce the application cost.The mechanism of the polyamines on AKD sizing is mainly considered to reduce anionic trash content in the slurry and to increase fines retention.
