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 obtain a balance between the bulk and the strength of paper, the poplar PRC-APMP slurry with different freeness is distributed to make better use of the organic pulp. The results showed that under the optimum conditions of 60mLCSF filled slurry (slurry with low freeness), 600mLCSF with skeletal slurry (high-free slurry) and the ratio of 0.14: 1, the bulk of paper was 2.437cm3 · g-1, The tensile index was 33.2N · m · g-1 and the internal bond strength was 272.3J · m-2. Compared to the puree, the ratio of the slurry increased the bulk of the paper by about 6%, and the tensile strength and internal bond strength increased by about 20% and 31%, respectively. Compared with the air-dried, drying drying is not conducive to observe the changes in bulk paper thickness.
