摘 要: 阳离子淀粉由于其含有阳离子基团在造纸和纺织工业显示出越来越重要的作用,文中对不同取代度的阳离子淀粉的布拉班德粘度曲线、淀粉糊透明度和凝沉性进行研究,发现阳离子淀粉的糊化温度、糊的凝沉性比原淀粉均有所降低,且随取代度的增加而降低,糊最高黏度和透明度比原淀粉高,随取代度的增加而增高。 Cationic starch is more and more important in the paper manufacturing and textile industry because of cationic groups. Brabender viscograph, paste transparency and gel property of cationic starch with different substituted degree were studied in the text: it was found that as substituted degree increased, gel temperature, paste gel property reduced compared to natural starch; while maximum viscidity and transparency of cationic starch paste increased and the properties become better.
