| 摘 要： | 研究了阳离子环糊精（c—CD）／高阳离子度淀粉（HcS）／阴离子聚丙烯酰胺（APAM）三元体系对废纸脱墨浆DCs的控制效果。结果表明：C-CD／HCS／APAM三元体系对废纸脱墨浆DCS有很好的协同控制效果，其控制效果好于C-CD／APAM双元体系和C—CD单一体系。在C-CD／HCS／APAM三元体系协同作用中，C-CD最佳用量为0．6％、HCS为0．1％、APAM为0．05％；在该C-CD／HCS／APAM三元体系作用T废纸脱墨浆的zeta电位开始逐渐增加，浆料滤水性能改善显著，浆料DCS水的浊度下降80％，阳离子需求量下降显著，且C-CD依靠其改性后仍然保留的独特“锥筒”状空腔结构，使DCs水的电导率下降约10％。

| Abstract: | The controlling effect of a triple system,composed of cationicmodified cyclodextrin(C-CD),high substitution cationic starch(HCS) and anionic polyacrylamide(APAM),on dissolved and colloidal substances(DCS) in waste paper deinked pulp was studied.The results show that DCS controlling effect of the C-CD/HCS/APAM triple system is better than that of the C-CD/APAM dual system and the single C-CD system in deinked pulp.In the C-CD/HCS/APAM triple system,when C-CD dosage is 0.6%,HCS 0.1% and APAM 0.05%,the Zeta po... |
