| 摘要:本研究以构皮为原料，采用均质处理技术制备了微纤化纤维素（MFC），探究不同尺寸MFC及其配加量对棉浆纸张性能的影响，进而反应其细小纤维对纸张性能的精准调控。结果表明，连续高压均质处理可以促使植物纤维的纤维束解离微纤化，经20次高压均质处理可获得直径约(84±16) nm的MFC。MFC-20具有较大比表面积，使纸张结构变得致密化，导致浆料滤水时间增加（28.5 s）和纸张的透气度下降明显。然而，仅1%添加量的MFC-10，可使纸张耐折度迅速提升至2 089次。 |
| Abstract:In this study， microfibrillated cellulose (MFC) from Broussonetia Papyrifera bark was prepared by homogenization technology. The effects of different sizes of MFC and their addition amounts on the properties of cotton pulp paper were investigated to reflect the precise regulation of fine fibers on paper properties. The results showed that continuous high-pressure homogenization treatment could promote the dissociation and microfibrillation of plant fibers. After 20 times of high-pressure homogenization treatment， MFC with a diameter of about (84±16) nm could be obtained. MFC-20 had a larger specific surface area， which made the paper structure denser， resulting in an increase in the drainage time of the pulp (28.5 s) and a significant decrease in the air permeability of the paper. However， only 1% addition of MFC-10 could rapidly increase the folding endurance of the paper to 2 089 times. |
