马尾松机械浆配抄阔叶木浆对成纸性能的影响

Impact of Masson pine CTMP composed with hardwood pulp on paper properties

研究了马尾松CTMP与阔叶木浆配抄对成纸质量的影响,将漂后马尾松CTMP分别以质量比10%、20%、30%、40%、50%的比例与阔叶木浆混抄,检测成纸的物理性能。结果表明:马尾松机械浆的配抄比例从10%增加到50%时,纸张的白度下降6.6%,抗张指数、撕裂度以及不透明度分别增加46.4%、60.0%和3.81%。

In this paper, impact of Masson pine chemical thermal mechanical pulp composed with hardwood pulp on paper properties was investigated. Masson pine CTMP was mixed with hardwood pulp at the proportion of 10%, 20%, 30%, 40%, and 50% to make paper sheet, whose physical properties were measured. The results show that paper brightness decreases by 6.6%, while tensile index, tear index and opacity increases by 46.4%, 60.0% and 3.81% respectively with the Masson pine CTMP proportion increased from 10% to 50%.
