本文研究了聚合物及非离子型表面活性剂浓度对混悬剂重分散的影响。所试表面活性剂为 Nonylphenylethoxylate 类(以下简称NPE),聚合物为不同分子量(5100～95900)的 PVA,混悬药物为平均粒径12.5μm、表面积1.206m~2·g~(-1)的安特酰胺糠酸酯(diloxa- The effect of polymer and non-ionic surfactant concentrations on the redispersion of suspending agents was investigated in this paper. The surfactants tested were nonylphenylethoxylate (hereinafter referred to as NPE) and the polymers were PVA with different molecular weight (5100-95900). The suspensions were as follows: average particle size 12.5 μm, surface area 1.206 m 2 · g -1 Diloxa-
