摘要
从氧化、羧基化、酯化、接枝共聚、醚化等改性方法入手,对淀粉絮凝剂的制备和应用进行了介绍,对比分析了各工艺的特点,总结了面临的问题,展望了今后的研究方向。指出:进一步丰富醚化剂的种类、对淀粉进行复合型改性、淀粉絮凝剂与传统絮凝剂复配使用是该领域的发展趋势。
Based on the modification methods such as oxidation,carboxylation,esterification,graft polymerization,etherification,and so on,the preparation and application of starch flocculants are introduced.The characteristics of the preparing techniques are discussed and their problems are summarized.The directions for further research are prospected.The development trends are pointed out,such as:finding more kinds of etherification reagent,complexly modifying starch,compounding starch flocculants with traditional flocculants,and so on.
