YF338两性淀粉 |
YF338浆内添加增强淀粉的特性介绍 YF338 Strengthened Starch Character Introduction 江西雨帆农业发展有限公司生产的YF338两性淀粉属阴、阳两性淀粉。这种型号的淀粉,在淀粉葡萄糖分子链上同时嫁接有阴离子和阳离子基团,因而它在浆料成份复杂的系统中使用,相对其它单一离子基团的淀粉,它具有以下独特的作用: 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、它所含的阴离子基团有助于清除体系中有碍淀粉吸附在纤维上的那些阴离子物质。 1. Anion group contained help to clean anion matters which impede starch adsorb in fiber. 2、分子中的阴离子基团能对阳离子基团起保护作用。电性排斥那些体系中存在的高活性“杂”阴离子,从而使淀粉中的阳离子基团不会发生过早的反应或被“杂”阴离子中和掉。 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、由于纤维带负电荷,故容易吸附阳离子淀粉,但对其他带正电荷的物质也易吸附。这会减弱淀粉与纤维的吸附,而两性变性淀粉中的阴离子基团能给予弥补。 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、两性变性淀粉的电荷基本平衡,那些未被留着的淀粉随水排出后,再循环使用水时,不会失去电荷平衡,从而保持良好的机械运转状态。 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、在中碱性体系中,离子电荷的平衡敏感度较大,即体系中较易出现过阳离子化,这就构成了“失控”状态。两性变性淀粉使体系的可控程度大大提高,从而也便于使用。 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、在文化纸中使用,因原料采用木薯淀粉生产,不仅具有较好的增强效果,同时还具有较好的助留效果。 6. Using cultural paper, cassava starch is used to produce material, it not only is more buildup effect, but also more assistance stay effect. |
