YF318阳离子淀粉产品特性

　　characteristics of YF318 cationic starch

　　YF318浆内添加淀粉属季铵型阳离子淀粉.该淀粉在淀粉分子链上嫁接了较多阳离子基团,因而在造纸浆料系统中,除能与纤维结合提高成纸内聚力、抗张强度、耐折次数等物理指标以外,还同时对细小纤维和填料物质起到较好的助留作用,因而能明显地降低网下白水浓度,提高留着率并能有效地改善浆料的滤水性.有利于纸页脱水,提高车速.

　　YF318 pulp-add starch is a kind of quaternary ammonium cationic starch.It has been grafted many cationic groups on the molecule chains of the starch.Not only can it improve the paper physical index of cohesive force,tensile strength and folding strength,but also it will help to remain the fines and fillers,therefor it can obviously lower the consistency of white water,increase the retention and improve the drainability of the pulp effectively,so it will help paper dewatering and heighten the speed of the paper machine.
