在实验室制备了CEH、DQP和DEopD三种漂白NaOH-AQ麦草浆,并通过纸页成形、压榨、干燥模拟造纸过程,得出了这三种漂白麦草浆循环回用过程中纸浆物理性质的变化。在此基础上,本文引入一种测定纤维“脱臼”点的方法,通过循环回用过程中纤维“脱臼”点的变化来反映纤维的损伤程度及其所引起的纤维强度性能的变化。 Three kinds of bleached NaOH-AQ wheat straw pulp, CEH, DQP and DEopD, were prepared in the laboratory. The papermaking process was simulated by paper forming, pressing and drying. The physical properties of the three bleached wheat straw pulp during recycling were obtained Variety. On this basis, this paper introduces a method to determine the fiber “dislocation ” point, through the recycling of fiber “dislocation ” point changes to reflect the degree of fiber damage and the fiber strength caused by its performance Variety.
