摘　　要：为分析电加热卷烟烟气中烟碱、甘油以及1,2-丙二醇等关键成分通过滤嘴时的截留行为,研究烟气关键成分在不同滤嘴中的截留率,通过建立描述电加热卷烟复合滤嘴截留率的线性模型与指数模型,考察了不同长度滤嘴中空段、聚乳酸段及醋酸纤维段对3种关键烟气成分截留率的影响。结果表明:①线性模型与指数模型均能预测卷烟滤嘴对加热卷烟烟气关键成分的截留率;②中空材料截留率最低,聚乳酸材料截留率居中,醋纤材料截留率最高,三者之间依次近似满足1∶2∶3的关系;③中空材料对甘油和丙二醇的截留能力强于烟碱,聚乳酸材料对甘油的截留能力则相对更高;④醋纤段对4种关键成分截留能力基本一致,无选择性。本研究结果可为电加热卷烟滤嘴结构设计与定量优化提供参考。To investigate the retention behaviors of filters in electrically heated tobacco products(EHTPs)to the key aerosol components(nicotine,glycerin and 1,2-propanediol)of EHTPs,the amount of the components retained by different filters and different filter segments(i.e.,cavity cellulose acetate section,polylactic acid section and cellulose acetate section)were measured.The retention rates were studied through a linear model and an exponential model to characterize the combined filters of EHTPs.The results showed that:1)Both the linear model and the exponential model could predict the retention rates of the key components in aerosols by the filters of EHTPs.2)The retention rate by the cavity cellulose acetate section was the lowest,that of the polylactic acid section was moderate and that of the cellulose acetate section was the highest.The relationship between these three sections approximately met 1∶2∶3.3)The retention rates of glycerol and 1,2-propylene by the cavity cellulose acetate section were higher than that of nicotine,and the retention ability of polylactic acid section to glycerol was relatively higher.4)The retention abilities of cellulose acetate section to the three key components were basically the same.This study provides a mechanistic basis for the structural design and quantitative optimization of filters for EHTPs.
