摘　　要：为了获得纸张松厚度与强度的平衡,通过不同游离度杨木PRC-APMP浆料进行配抄,以期更好地使用化机浆。结果显示,在填充浆(低游离度浆料)60mLCSF,骨架浆(高游离度浆料)600mLCSF,配比为0.14:1的最佳工艺下,成纸松厚度为2.437cm3·g-1,抗张指数为33.2N·m·g-1,内结合强度为272.3J·m-2。配比浆料与原浆相比,成纸的松厚度提高约6%,抗张强度和内结合强度分别提高约20%和31%。与风干干燥相比,烘干干燥不利于观察成纸松厚度的变化。In order to have the balance between the bulk and tensile strength, through mixing different freeness pulps to achieve the mixed pulp. The results showed that the best process is as follows： freeness of the backbone pulp is 600 mL; freeness of the appended pulp is 60 mL; the ratio is 0.14：1; the bulk is 2.437 cm ^3 ·g^- 1 ; the tensile index is 33.2 N·m·g^- 1 , and the internal bond strength is 272.3 J·m^- 2 . Compared with the primary pulp, the bulk of mixed pulp is improved by 6%. And tensile and bond of mixed pulp are obviously increased by 20% and 31% than original pulp, respectively. e oven dry is not favor of observe the bulk change.
