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%。
Through the modification of different fiber raw materials, and studied the effect of different fiber modification on paper properties. The results show that different fibers modified to add paper pulp, the strength of the paper are beneficial. After the kraft pulp was partly modified, the tensile index increased from 38.28N · m · g-1 to 47.21N · m · g-1 and the tear index increased by 10.92% after adding 5% After the modified pulp was modified, 1.5% of the pulp was added into the pulp, the bonding strength increased from 49.41J · m-2 to 55.30J · m-2, the tensile index increased 48.06% In OCC pulp, the tensile index increased from 18.89N · m · g-1 to 27.55N · m · g-1, and the crush strength index increased by 13.99%.
