| 摘要:为探究烟粉添加对固液耦合涂布效果的影响，本研究通过开展烟粉性能分析，主要探讨了烟粉添加对涂布效果、烟草薄片理化指标的影响。结果表明，烟粉的添加导致涂布液密度、固含量、黏度增加，且黏度增加最快，烟粉添加量对涂布液的影响大于其粒径。烟粉的添加引起烟草薄片抗张强度增加，柔软度和透气度减小。适宜的烟粉添加量应低于9%，粒径为500目左右。 |
| Abstract:In order to investigate the effect of tobacco powder addition on the coating effect of solid-liquid coupling， this study mainly discussed the effects of tobacco powder addition on coating effect and physical and chemical indexes of reconstituted tobacco through the analysis of tobacco powder properties. The results showed that the addition of tobacco powder led to an increase in density， solid content， and viscosity of the coating solution， and the viscosity increased the fastest， and the dosage affected the coating solution more than the particle size. The addition of tobacco powder caused an increase in tensile strength and a decrease in softness and air permeability of the reconstituted tobacco leaves. The appropriate proportion of added tobacco powder should be less than 9%， and the particle size was about 500 mesh. |
