摘要
通过对不同的纤维原料进行改性,并研究了不同纤维改性后对成纸的性能影响。结果表明,不同纤维经过改性后添加到纸浆中抄纸,对成纸的强度都是有利的。对硫酸盐浆进行部分改性后添加5%到浆料中,抗张指数可从38.28N·m·g-1提高到47.21N·m·g-1,撕裂指数增加10.92%;对高得率浆进行改性后添加1.5%到纸浆中,纸张内结合强度从49.41J·m-2提高到了55.30J·m-2,抗张指数增加48.06%;对木屑纤维改性后添加1.5%到OCC纸浆中,抗张指数从18.89N·m·g-1增加到27.55N·m·g-1,环压强度指数增加13.99%。
The different fiber materials were modified,and the effects of modified fiber on hand-sheet were evaluated in this paper.It＇s shown that,the strength of paper could be promoted by modified fiber.When the adding ratio of part modified fiber from NBKP was 5% in NBKP,the tensile index increased from 38.28N·m·g-1 to 47.21N·m·g-1.When the adding ratio of modified fiber from HYP was 1.5% in HYP,the internal bond of paper increased from 49.41J·m-2 to 55.30J·m-2 and the tensile index increased 48.06%.When the adding ratio of modified fiber from sawdust was 1.5% in OCC,the tensile index of paper increased from 18.89N·m·g-1 to 27.55N·m·g-1,and the same time,the ring crush index increased 13.99%.
