摘要: 利用在线激光打孔设备制作通风率不同的混合型卷烟和烤烟型卷烟,考察通风率对两种卷烟物理指标、常规烟气释放量的影响.结果表明:两种卷烟的总通风率、滤嘴通风率均与卷烟质量呈正相关,与吸阻呈负相关,且通风率越高,滤嘴通风率对总通风率的贡献越大;两种卷烟的总通风率、滤嘴通风率均与烟气烟碱、焦油和CO释放量呈显著负相关,影响大小依次为CO释放量> 焦油释放量> 烟碱释放量.根据卷烟烟气指标设计,可先计算总通风率,再通过调整在线激光打孔参数来满足卷烟产品设计要求.Abstract: In order to observe the effect of ventilation on cigarette physical and chemical properties, blended type and Virginia type cigarettes were made by online laser punching equipment. The results showed that ventilation rate of the two types of cigarettes was positively related with cigarette weight, and negatively related with cigarette resistance. The higher the ventilation rate was, the more the filter ventilation rate contributed to the total ventilation rate. The two types of cigarettes ventilation rate and filter ventilation rate had negative correlation with the release of nicotine, tar and carbon monoxide. Carbon monoxide was most affected, followed by tar, and nicotine was least affected. Once the cigarette properties were fixed, ventilation rate could be calculated firstly,then through adjusting the laser perforation parameters online, cigarette design demands could be met.
