基于烟支损失质量的三种加热卷烟基棒截留效果研究

Study on the retention effect of three HTPs base rods based on the cigarette lose mass

【目的】研究加热卷烟基棒材料对烟气释放质量的影响。【方法】基于加热卷烟逐口烟支损失质量(Cigarette lose mass,CLM)测量装置,选取市售加热卷烟,截取烟丝段增加烟气连接段制作参考样品,在参考样品后增加不同长度或材料基棒制作测试样品,参照ISO标准抽吸模式,测量参考样品和测试样品逐口CLM的变化,以测试样品相对参考样品的CLM减少率作为截留率。【结果】(1)参考样品第1口的相对标准偏差为5.92%,第2口至第6口相对标准偏差最大值为3.39%,选取的市售加热卷烟烟丝段烟气释放质量较为稳定;(2)截留率随着基棒长度增加而增加,当基棒长度从5 mm增加到20 mm时,中空基棒、PLA基棒、醋纤基棒截留率分别增加7.49%、21.56%、17.09%;且截留率:中空基棒<醋纤基棒<PLA基棒;(3)PLA基棒为20 mm、醋纤基棒大于等于10 mm后逐口的截留率呈现递减趋势。

This study aims to investigate the impact of HTPs(Heated Tobacco Products)base rods material on smoke emission quality.Based on the Cigarette Loss Mass(CLM)measurement device for heating cigarettes,commercially available heating cigarettes were selected.Reference samples were made by cutting the tobacco section and adding a smoke connection section.Test samples were made by adding rods of different lengths or materials to the reference samples.Using the ISO standard smoking regime,the change in CLM per puff was measured for both reference and test samples.The retention rate was calculated as the reduction rate of CLM for test samples relative to reference samples The results show that:①The relative standard deviation of the reference sample from the first puff is 5.92%,and the maximum relative standard deviation from the second puff to the sixth puff is 3.39%.The smoke emission quality of the selected commercially HTPs is relatively stable.②As the length of the base rod increased from 5mm to 20mm,the retention rates of hollow base rod,PLA base rod and vinegar fiber base rod increased by 7.49%,21.56%and 17.09%,respectively.The retention rate followed the order:hollow base rod<vinegar fiber base rod<PLA base rod;③The retention rate per puff showed a decreasing trend after 20 mm for PLA rods and 10 mm for cellulose acetate rods.
