接装纸材质和激光打孔参数对卷烟的影响研究

目的 研究不同材质接装纸和激光打孔参数对在线激光打孔卷烟的影响。方法 应用扫描电镜检测卷烟样品的打孔微观结构，包括纸的表面形貌、打孔的大小、孔间距等指标，对相应接装纸的卷烟物理指标差异和烟气指标差异以及相关性进行研究。结果 激光打孔脉冲时间、打孔数量对激光打孔的微观形态有较大影响，打孔脉冲时间和打孔数量与卷烟烟支吸阻呈线性负相关，与总通风率呈线性正相关。在相同激光打孔参数下，不同接装纸材质纸张孔径和孔间距明显不同，单孔的形态差异较大;不同材质接装纸对卷烟物理指标影响较小，对卷烟烟气指标有一定影响。单孔打孔的高质量有利于提高卷烟物理指标和烟气指标的稳定。结论 不同材质接装纸的在线激光打孔应用效果不同，可以根据烟支设计需要进行选择接装纸材质。

Effect of Tipping Paper Materrials and Laser Punching Parameters on Cigarette

The work aims to investigate the effect of tipping paper of different materials and laser punching parameters on the cigarette made by online laser punching. The punching microstructure of cigarette sample was detected by scanning electron microscope, including the surface shape of paper, the size of punching and hole spacing. The differences in physical indexes and smoke indexes of cigarette sample made by corresponding tipping paper were studied and the correlation was explored. Laser punching pulse duration and hole number had great effect on the micro-morphology of laser punching. The punching pulse duration and the number of holes had a linear negative correlation with the cigarette draw resistance and a linear positive correlation with the total ventilation rate. The size and spacing of tipping paper of different materials were obviously different, and the morphology of single hole was also different. Different materials had little effect on physical indexes of cigarette, but had a certain effect on the smoke indexes. The high quality of single hole was beneficial to improving the stability of physical indexes and smoke indexes of cigarette. The application effect of online laser punching of tipping paper of different materials is different, but the material of tipping paper can be selected according to the design of cigarette.
