辅助材料设计参数对烤烟型卷烟烟气焦油、烟碱和CO释放量的影响

为探索辅助材料与卷烟烟气化学成分之间的关系,研究了卷烟纸定量、卷烟纸透气度、成形纸透气度、接装纸透气度和滤棒吸阻对卷烟主流烟气焦油、烟碱和CO释放量的影响,并通过辅材设计参数的组合设计,建立了辅材设计参数预测焦油、烟碱和CO释放量的数学模型.结果表明:①卷烟纸定量增加CO释放量增加；②卷烟纸透气度增加,焦油、烟碱和CO释放量降低；③滤棒吸阻增加,焦油和烟碱释放量降低；④接装纸透气度增加,焦油、烟碱和CO释放量显著降低；⑤成形纸透气度增加,焦油、烟碱和CO释放量降低,降低程度与配合使用的接装纸透气度有关；⑥焦油、烟碱和CO释放量预测模型的预测值与实测值基本吻合.

Effects of Material's Parameters on Deliveries of Tar, Nicotine, and CO in Mainstream Smoke of Virginia Type Cigarettes

In order to investigate the relationships between cigarette materials and chemical components in mainstream cigarette smoke,the effects of grammage and air permeability of cigarette paper,air permeability of tipping paper and plug wrapper,and draw resistance of filter on the deliveries of tar,nicotine,and CO in mainstream smoke of Virginia type cigarettes were studied,and the mathematical models for predicting the deliveries of tar,nicotine and CO in mainstream smoke on the basis of material parameters were established.The results showed that: 1) The delivery of carbon monoxide in mainstream smoke increased with the increase of cigarette paper grammage.2) The deliveries of tar,nicotine and carbon monoxide in mainstream smoke reduced with the increase of air permeability of cigarette paper.3) The deliveries of tar and nicotine in the smoke reduced with the increase of draw resistance of filter.4) The deliveries of tar,nicotine and carbon monoxide in the smoke decreased obviously with the increase of air permeability of tipping paper.5) The deliveries of tar,nicotine and carbon monoxide in the smoke reduced with the increase of air permeability of plug wrapper,the reduction extent related with the air permeability of tipping paper.6) The predicted values by the models basically agreed with the determined values.
