通过向纸浆中添加纳米纤维素、纳米蒙脱土和木聚糖,研究添加纳米材料对纸张性能的影响。结果表明:当在纸浆中添加纳米纤维素的量为0.5%时,各项强度指数提高最大:纸张紧度提高15.6%,耐折度提高165%,撕裂指数提高23.8%,抗张指数提高15.8%,光散射系数下降18.3%。电镜分析表明纳米纤维素的添加可以增加纸张的结合。 The effects of adding nanomaterials on paper properties were investigated by adding nanocellulose, nano-montmorillonite and xylan to the pulp. The results showed that when the amount of nanocellulose added in pulp was 0.5%, the maximum of each index of strength was increased: the tightness of paper increased 15.6%, the folding endurance increased 165%, the tear index increased 23.8% and the tensile index increased 15.8%, light scattering coefficient decreased 18.3%. Electron microscopy analysis showed that the addition of nanocellulose can increase the binding of paper.
