抽吸模式对纸打孔细支卷烟烟气释放量的影响

为研究卷烟纸打孔细支卷烟的主流烟气,测定不同卷烟纸打孔参数的细支卷烟在ISO和HCI 2种模式下焦油和烟碱逐口释放量。结果表明:(1)ISO模式下卷烟纸打孔细支卷烟样品的焦油释放量有不同程度降低,而烟碱释放量变化幅度不明显;(2)HCI模式下,纸打孔样品焦油和烟碱总释放量均有不同程度升高,卷烟纸打孔对细支卷烟焦油和烟碱总释放量有不利影响;(3)前3口焦油增长率的变化反映了ISO模式下焦油逐口释放量的变化趋势较HCI模式大;(4)ISO模式下,纸打孔卷烟总烟碱/焦油比均大于对照样,且在打孔数目相同的情况下,总烟碱/焦油比随孔带宽度增加而增加,孔带宽度相同时,烟碱/焦油比随打孔数目增加而升高。而HCI模式下打孔卷烟与对照样烟碱/焦油比未呈现明显的变化规律。

Effect of smoking regimes on smoke release of super slim cigarettes with perforation paper

In order to study the mainstream smoke of the super slim cigarettes with perforation cigarette paper. The tar and nicotine deliveries on a puff-by-puff basis of the super slim cigarettes with different cigarette paper perforation parameters were measured under ISO and HCI regimes respectively. The results showed that: 1) Under ISO regime, tar deliveries of the perforation super slim cigarettes decreased, and there were no obvious variations of nicotine between the perforation cigarettes and the control samples. 2) Under HCI regime, tar and nicotine deliveries of perforation cigarettes increased, and the perforation had a negative effect on the total tar and nicotine deliveries of super slim cigarettes. 3) The tar growth rate of the first three puff showed that the variation tendency of tar release per puff under ISO regime was larger than that under HCI regime. 4) Under ISO regime, the total nicotine/tar ratios of perforation cigarettes were larger than that of the control samples. The total nicotine/tar ratio increased with the increase of perforation band under the same number of perforation, and the nicotine/tar ratio increased with the increases of the number of perforation under the same perforation band. There were no regular variation of the nicotine/tar ratio between perforation cigarettes and control samples under HCI regime.
