等离子和静电打孔接装纸特性及其对卷烟物理和常规烟气指标的影响

  目的  为综合对比评价等离子打孔和静电打孔接装纸的特性及其对卷烟物理指标和常规烟气成分释放量的影响。  方法  采用两种打孔方式不同透气度和不同孔带宽度的接装纸进行电镜扫描和卷烟试验。  结果  （1）试验条件下，静电打孔接装纸比等离子打孔接装纸的孔密度更高、孔径更小。（2）在相同孔带宽度和接装纸透气度下，静电打孔和等离子打孔卷烟的吸阻稳定性、总通风率稳定性和常规烟气成分释放量无显著差异，静电打孔卷烟滤嘴通风率稳定性优于等离子打孔。（3）增加打孔宽度可提高卷烟滤嘴通风率的稳定性，可降低焦油量、烟气烟碱量和一氧化碳量等常规烟气指标。  结论  从烟支物理特性及降低焦油、烟碱和一氧化碳的角度，等离子打孔和静电打孔可以实现等同应用，应尽量增加打孔密度，减小打孔孔径，并增加打孔宽度。 

Characteristics of plasma and electrostatically perforated tipping papers and their influence on physical and regular smoke indicators of cigarettess

  Background  This study aims to evaluate the characteristics of plasma and electrostatic perforation tipping papers and their influence on cigarette physical indicators and the releasing amount of routine smoke components.  Methods  Electron microscope scanning and cigarette tests were carried out by using two types of perforation tipping papers with different porosity levels and different pore widths.  Results  Under test conditions, electrostatic perforation tipping paper had higher pore density and smaller pore diameter compared with plasma perforation tipping paper. Under the same pore width and porosity level, there were no significant differences in the suction stability, total ventilation stability and release amount of conventional smoke components between electrostatic and plasma perforated tipping papers. Filter ventilation stability of electrostatic perforated cigarettes was better than that of plasma perforated cigarettes. Increasing pore width could improve cigarette filter ventilation stability, and reduce the release amounts of regular smoke components such as tar, nicotine and carbon monoxide.  Conclusion  In the aspects of cigarette physical properties and reduction of tar, nicotine and carbon monoxide, plasma perforation and electrostatic perforation could be applied equally. The pore density and pore width should be increased as much as possible, while pore diameter should be minimized.
