　　YF402表(biao)面施膠淀(dian)粉(fen)的特性介紹

　　YF402 Surface Sizing Starch Character Introduction

　　該(gai)品(pin)種淀(dian)粉(fen)(fen)是采(cai)用次氯酸鈉(na)為氧(yang)化劑(ji)及濕法工藝(yi)生(sheng)產的(de)氧(yang)化淀(dian)粉(fen)(fen)。該(gai)品(pin)種淀(dian)粉(fen)(fen)蒸煮糊(hu)化后(hou)淀(dian)粉(fen)(fen)糊(hu)液(ye)均勻透(tou)明，糊(hu)液(ye)穩定。在文(wen)化用紙(zhi)(zhi)的(de)生(sheng)產中，使用該(gai)品(pin)種淀(dian)粉(fen)(fen)對紙(zhi)(zhi)張進(jin)行表面施膠可顯著提高(gao)(gao)紙(zhi)(zhi)張的(de)表面強度，減少紙(zhi)(zhi)張在印刷中的(de)掉毛(mao)、掉粉(fen)(fen)現象，并適當進(jin)一步改進(jin)紙(zhi)(zhi)張的(de)施膠度。因為羧基的(de)存在，使得(de)淀(dian)粉(fen)(fen)顆粒糊(hu)化后(hou)產生(sheng)了更多的(de)氫鍵，這些氫鍵增加了淀(dian)粉(fen)(fen)對紙(zhi)(zhi)張纖維(wei)的(de)粘結力從(cong)而得(de)到強度更高(gao)(gao)的(de)淀(dian)粉(fen)(fen)膜。

　　This type of starch is oxidized starch produced by wet process, adopting sodium hypochlorite as oxidizing agent. The starch paste is even, transparent and stable after cooking. In cultural paper production, use this kind of starch could increase paper surface strength; reduce linting and pull-up when printing. Because of the existence of carboxyl, made starch granule after gelatinization bring more hydrogen bonds. These hydrogen bonds strengthen fiber cohesive force between starch and paper; thereby gain better strength starch film.
