| 摘要:为了改善烟草薄片的物理性能，在造纸法烟草薄片的涂布过程中加入纳米纤维素，并探究其对烟草薄片物理性能的影响，且对纳米纤维素种类和添加量进行了优化。结果表明，选用的3种纳米纤维素中，纤维素纳米晶体（CNC）的综合效果最佳，且用量为0.1%时（以涂布液的固含量计）效果最好。另外，CNC的添加对涂布液的黏度无负面影响，抗张指数由对照组（不加CNC）的10.1 N·m/g，增加到13.3 N·m/g，增幅达到了32.6%；表面强度由对照组的1.35m/s，增加到了1.74m/s，增幅达到了28.89%。 |
| Abstract:To improve the physical properties of tobacco sheet， the effect of adding nano-cellulose to the coatings on the properties of tobacco sheet during the coating process of papermaking tobacco sheet was discussed， and the kinds and dosage of nano-cellulose were optimized.The results showed that the effect of CNC was the best among three kinds of nano cellulose. It was more appropriate to add 0.1% CNC （based on the dried coating）. The addition of CNC had no negative effect upon coatings. The tensile index of the tobacco sheet increased from 10.1 N·m/g （the control group） to 13.3 N·m/g. The increment reached 32.6%. And surface strength increased from 1.35m/s （the control group） to 1.74m/s. The increment reached 28.9%． |
