摘　　要：利用槽式打浆机对杨木P-RC APMP进行不同程度打浆,获得高游离度浆和低游离度浆,研究了两者配抄对杨木P-RC APMP成纸性能的影响因素,并与传统浆的性能进行对比。结果表明:通过槽式打浆机构建的改良化机浆,影响其成纸松厚度、抗张指数的主要因素顺序为:高游离度浆>低游离度浆添加比例>低游离度浆;在相同的抗张强度下,改良化机浆可以获得比传统浆更高的松厚度。The pulps with high freeness and low freeness were prepared by beating poplar P-RC APMP with a Valley beater, the effects of different freeness pulps on paper properties were studied. The results showed that the sequence of main factors influencing on the bulk and tensile index of the paper sheet was： high freeness pulp 〉 the proportion of low freeness 〉 low freeness pulp ; and the mixed pulp had a better bulk compared to the traditional pulp at a given tensile strength.
