　　YF318陽(yáng)離子淀粉產(chǎn)品特性

　　characteristics of YF318 cationic starch

　　YF318漿內(nèi)添加淀粉屬季銨型陽(yáng)離子淀粉.該淀粉在淀粉分子鏈上嫁接了較多陽(yáng)離子基團(tuán),因而在造紙漿料系統(tǒng)中,除能與纖維結(jié)合提高成紙內(nèi)聚力、抗張強(qiáng)度、耐折次數(shù)等物理指標(biāo)以外,還同時(shí)對(duì)細(xì)小纖維和填料物質(zhì)起到較好的助留作用,因而能明顯地降低網(wǎng)下白水濃度,提高留著率并能有效地改善漿料的濾水性.有利于紙頁(yè)脫水,提高車速.

　　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.
