摘　　要：用不同方法对玉米淀粉进行了改性,制备出一系列改性淀粉,测定了各产物的粘度、接枝率等性能指标并用高岭土悬浊液对产物做了初步絮凝对照。结果表明在单独用作絮凝剂使用时,氯乙酸接枝胺化淀粉(CGMS)和阳离子改性淀粉(GMS)的效果明显高于其他产物;在加入PAM作助凝剂后,马来酸接枝胺化淀粉(MGMS)的絮凝效果明显提高,最佳效果可达88%,絮凝瞬间完成。Corn starch was used in the synthesis of a series of modified starch flocculants through different methods with different kinds of reagent.The viscosity and grafting ratio of the new products were measured and so on.The flocculation properties of modified starch toward the water of kaolin were also studied.The experimental results showed that the flocculating activity of the CGMS and CS were higher than other products obviously without PAM.As the PAM used,the flocculating activity of MGMS was improved obviously and the highest flocculating ratio was 88%.
