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 pulping of poplar P-RC APMP was carried out by beating pulverizer to obtain high-free pulp and low-free pulp, and the influencing factors on the paper-making performance of poplar P-RC APMP were studied. The performance of traditional pulp is compared. The results showed that the order of the main factors affecting the slab thickness and tensile index of the modified pulp produced by the slot beater was as follows: high-free pulp> low-free pulp> low-free pulp; Of the tensile strength, improved mechanical pulp can get higher than the traditional pulp bulk.
