　　YF338漿內(nèi)添加增強(qiáng)淀粉的特性介紹

　　YF338 Strengthened Starch Character Introduction

　　江西雨帆農(nóng)業(yè)發(fā)展有限公司生產(chǎn)的YF338兩性淀粉屬陰、陽兩性淀粉。這種型號的淀粉，在淀粉葡萄糖分子鏈上同時(shí)嫁接有陰離子和陽離子基團(tuán)，因而它在漿料成份復(fù)雜的系統(tǒng)中使用，相對其它單一離子基團(tuán)的淀粉，它具有以下獨(dú)特的作用：

　　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、它所含的陰離子基團(tuán)有助于清除體系中有礙淀粉吸附在纖維上的那些陰離子物質(zhì)。

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

　　2、分子中的陰離子基團(tuán)能對陽離子基團(tuán)起保護(hù)作用。電性排斥那些體系中存在的高活性“雜”陰離子，從而使淀粉中的陽離子基團(tuán)不會發(fā)生過早的反應(yīng)或被“雜”陰離子中和掉。

　　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、由于纖維帶負(fù)電荷，故容易吸附陽離子淀粉，但對其他帶正電荷的物質(zhì)也易吸附。這會減弱淀粉與纖維的吸附，而兩性變性淀粉中的陰離子基團(tuán)能給予彌補(bǔ)。

　　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、兩性變性淀粉的電荷基本平衡，那些未被留著的淀粉隨水排出后，再循環(huán)使用水時(shí)，不會失去電荷平衡，從而保持良好的機(jī)械運(yùn)轉(zhuǎn)狀態(tài)。

　　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、在中堿性體系中，離子電荷的平衡敏感度較大，即體系中較易出現(xiàn)過陽離子化，這就構(gòu)成了“失控”狀態(tài)。兩性變性淀粉使體系的可控程度大大提高，從而也便于使用。

　　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、在文化紙中使用，因原料采用木薯淀粉生產(chǎn)，不僅具有較好的增強(qiáng)效果，同時(shí)還具有較好的助留效果。

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