研究了马尾松BCTMP浆和阔叶木化学浆纤维的形态特征,以及两种浆配抄对成纸质量的影响.研究发现,马尾松CTMP浆纤维挺硬,没有呈现弯曲、扭结的状态;而阔叶木漂白化学浆纤维柔软,纤维呈现出弯曲的形态,并且纤维之间相互缠绕、扭结,这种形态有利于纤维之间的结合.将马尾松BCTMP浆分别以质量比10%,20%,30%,40%,50%的比例与阔叶木漂白化学浆混合,抄造成纸.结果表明,马尾松BCTMP浆的配抄比例从10%增加到50%时,纸张的白度下降2.1%,抗张指数、撕裂度分别下降28.4%、10.8%,不透明度增加1.1%.
The morphological characteristics of BCTMP and hardwood chemical pulp fibers were studied, and the effects of two kinds of pulp preparation on the paper quality were studied. The results showed that the CTM pulp fibers of the Masson Pine were stiff, without bending and kinking; The bleached chemical pulp fibers are soft, the fibers show a curved shape, and the fibers are intertwined and kinked together, which is in favor of the bonding between the fibers. The mass ratio of the masson pine BCTMP pulp is 10%, 20%, 30% %, 40% and 50% blends with hardwood bleached chemical pulp, the paper was made into paper.The results showed that when the mass ration of masson pine BCTMP increased from 10% to 50%, the whiteness of the paper decreased by 2.1% Zhang index, tearing degree drops respectively 28.4%, 10.8%, the opacity increases 1.1%.
