卷烟纸参数对细支卷烟烟气常规成分释放量的影响

Influence of cigarette paper parameters on the release of routine chemical components in mainstream smoke of slim cigarette

为研究细支卷烟卷烟纸参数(定量、透气度、助燃剂中钾钠比,以及麻浆、灰分和助燃剂的质量分数)对烟气常规成分释放量的影响,根据国内外细支烟用卷烟纸的设计特点进行了样品设计和制作,分析了细支烟卷烟纸参数对烟气常规成分释放量的影响,并与常规卷烟进行了对比。结果表明:(1)透气度、助燃剂质量分数、钾钠比与细支烟主流烟气焦油、烟碱和CO的释放量呈现强的负相关关系。相同的助燃剂质量分数和钾钠比增加幅度,细支烟焦油、烟碱和CO释放量的降低率比常规卷烟大;相同的透气度增加幅度,常规卷烟焦油、烟碱和CO释放量的降低率比细支烟大。(2)卷烟纸定量与细支烟焦油和烟碱的释放量具有一定的负相关关系,与CO释放量具有一定的正相关关系。相同的定量增加幅度,细支烟焦油和烟碱释放量降低率比常规卷烟大,细支烟CO释放量降低率与常规卷烟基本一致。(3)麻浆和灰分的质量分数与细支烟焦油释放量均具有一定负相关关系,与烟碱和CO的释放量不相关;常规卷烟卷烟纸麻浆和灰分质量分数对烟气常规成分释放量影响不明显。

To investigate the relationships of cigarette paper parameters（grammage,air permeability,K/Na ratio,hemp pulp content,ash content and burn promoter content） with the releases of routine chemical components in mainstream smoke of slim cigarettes,slim cigarette samples were designed and manufactured according to the performance features of imported and domestic slim cigarette paper.The influences of cigarette paper parameters on the releases of routine components in mainstream smoke were compared with those of kingsized cigarettes.The results showed that： 1） The air permeability,burn promoter content and K/Na ratio showed a strong negative correlation to the releases of tar,nicotine and CO in mainstream smoke.At the same increasing extent of burn promoter content and K/Na ratio,the reduction rate of tar,nicotine,and CO in mainstream smoke were higher than those of kingsized cigarettes.A contrary trend was observed at the same increasing extent by paper air permeability.2） Paper grammage negatively correlated to tar and nicotine releases,positively correlated to CO release.At the same increasing extent of paper grammage,the reduction rates of tar and nicotine levels in mainstream smoke were higher than those of kingsized cigarettes,while the reduction rate of CO release was basically the same as that of kingsized cigarettes.3） The hemp pulp content and ash content in the paper negatively correlated to the tar release in mainstream smoke to a certain extent,and did not correlated to nicotine and CO releases.The hemp pulp content and ash content in kingsized cigarette paper had no obvious influences on the releases of routine chemical components in mainstream smoke of kingsized cigarette.
