　　YF338漿內(nei)添加增強淀粉(fen)的(de)特性介紹

　　YF338 Strengthened Starch Character Introduction

　　江西雨帆農業(ye)發展有(you)限公司(si)生產的YF338兩(liang)性(xing)淀(dian)粉(fen)屬(shu)陰、陽(yang)兩(liang)性(xing)淀(dian)粉(fen)。這種型號(hao)的淀(dian)粉(fen)，在淀(dian)粉(fen)葡萄糖分子(zi)(zi)鏈上同時嫁(jia)接有(you)陰離(li)子(zi)(zi)和陽(yang)離(li)子(zi)(zi)基(ji)團(tuan)，因而它在漿(jiang)料成份復(fu)雜的系統中使用(yong)，相對其它單一(yi)離(li)子(zi)(zi)基(ji)團(tuan)的淀(dian)粉(fen)，它具有(you)以下獨特(te)的作用(yong)：

　　YF338 amphoteric starch contains anion and cationic two kinds of starch, produced by Jiangxi Yu Fan Agricultural Development Limited Company. This type of starch graft anion and cationic group at the same time on the starch glucose molecule chain. Therefore, compared with other single ion group starch, it has following unique functions while using in complex pulp content system:

　　1、它所含的(de)陰離(li)子基團有(you)助(zhu)于清除體系(xi)中有(you)礙淀粉吸附(fu)在(zai)纖維上(shang)的(de)那些陰離(li)子物(wu)質。

　　1. Anion group contained help to clean anion matters which impede starch adsorb in fiber.

　　2、分子中的陰(yin)離(li)子基(ji)團能對(dui)陽(yang)離(li)子基(ji)團起保護(hu)作用。電性排斥(chi)那(nei)些體系中存(cun)在的高活性“雜(za)”陰(yin)離(li)子，從而使淀(dian)粉中的陽(yang)離(li)子基(ji)團不會發生(sheng)過早的反(fan)應或被“雜(za)”陰(yin)離(li)子中和掉。

　　2. Anionic groups of molecule can protect cationic groups. Electrical exclude those highly active ‘mixed’ anions existed in the system, thus make the cationic starch groups won't react too early or neutralized by ‘mixed’ anion.

　　3、由于纖維帶(dai)負電荷，故容易(yi)吸附陽(yang)離子淀(dian)粉(fen)(fen)(fen)，但對(dui)其他帶(dai)正(zheng)電荷的物(wu)質也易(yi)吸附。這會(hui)減(jian)弱淀(dian)粉(fen)(fen)(fen)與纖維的吸附，而兩(liang)性(xing)變性(xing)淀(dian)粉(fen)(fen)(fen)中的陰離子基(ji)團能給予(yu)彌補。

　　3. Because fiber negatively charged, so easily to absorb cationic starch, but also easily to absorb other positively charged material. It will weaken absorption between starch and the fiber, and anionic group of amphoteric modified starch can compensate.

　　4、兩性變性淀(dian)粉(fen)的電荷(he)基本(ben)平衡，那些未被留著(zhu)的淀(dian)粉(fen)隨水排(pai)出后(hou)，再循環使用水時，不會失(shi)去(qu)電荷(he)平衡，從而保持良好的機械(xie)運轉狀態。

　　4. Amphoteric modified starch charge is balanced basically, the starch is not stayed and drain with the water, after water recycling, and it will not lose charge balance, thereby maintaining good mechanical operation conditions.

　　5、在中堿性(xing)體(ti)系(xi)中，離(li)子電荷的(de)平衡敏感度(du)較大，即(ji)體(ti)系(xi)中較易出(chu)現過陽離(li)子化(hua)，這就構(gou)成了“失(shi)控”狀態(tai)。兩性(xing)變性(xing)淀粉使(shi)(shi)體(ti)系(xi)的(de)可控程度(du)大大提(ti)高，從而(er)也便(bian)于使(shi)(shi)用。

　　5. In neutral and alkaline system, ion charge balance sensitivity is larger, that is easy to happen over-cationized in the system, then becomes ‘out of control’ situation. Amphoteric modified starch greatly increased the controllable degree in the system, and then also makes it easy to use.

　　6、在文化紙中(zhong)使(shi)用，因原(yuan)料采用木(mu)薯淀粉生產(chan)，不僅具有較好的增強效果(guo)，同時還(huan)具有較好的助留(liu)效果(guo)。

　　6. Using cultural paper, cassava starch is used to produce material, it not only is more buildup effect, but also more assistance stay effect.
