摘要 选用了 10种聚丙烯酰胺和 7种淀粉分别作助滤剂,通过测定其分子量、固含量、粘度、Ze ta电位、电荷密度及取代度等参数。 The draining characteristics of bleached wheat straw pulps with ten polyacrylamides and seven starches drainage aids have been studied. In the experiment the analytic methods of single-component and dual component system is more effective. Molecular weights,charge densties,viscosities,degree of substitution and Zeta potential of the systems are also studied. The results show that they are key factors of the drainage aid of bleached wheat straw pulps.
