摘要
【目的】研究醋纤滤嘴对挥发性羰基化合物的截留规律,为复合滤棒设计提供参考。【方法】将醋纤滤嘴轴向切分成段,在不同位置插入减害材料,考察截留情况。【结果】整支醋纤滤嘴对巴豆醛、丙醛、甲醛的截留率分别为53%、57.66%、38.35%,从烟丝端到嘴端,分段截留率均呈降低趋势;减害材料添加在滤嘴近嘴端,整支滤嘴对羰基化合物表现出更好的截留作用。【结论】为使整支滤嘴表现出更好的截留效果,在保障复合滤嘴安全性的前提下,应考虑将减害材料添加于滤嘴近嘴端。
In order to investigate the retaining behavior of cellulose acetate (CA) on volatile carbonyl compounds, axial sectional cellulose acetate filter samples and filter samples with harm reduction materials were prepared. Results showed that cellulose acetate filter had better filtration effects on crotonaldehyde(53%), propionaldehyde(57.66%) and formaldehyde (38.35%) and filtration rate decreased as cigarette mainstream smoke flowed towards the mouth end. When harm reduction materials were added to the section away from tobacco end, the filter showed better filtration effect.
