滤嘴参数对主流烟气Pb、As、Cd释放量的影响

Effects of Different Filter Parameters on Deliveries of Pb, As and Cd in Mainstream Smoke

为掌握不同滤嘴参数对主流烟气中Pb、As、Cd释放量的影响,通过卷制不同滤嘴参数卷烟,用吸烟机进行抽吸及测定主流烟气中Pb、As、Cd的释放量,结果发现:(1)不同种类滤嘴对主流烟气中Pb、As、Cd释放量的影响具有一定的选择性;(2)随着滤嘴长度的增加,主流烟气中Pb、As、Cd释放量均有不同程度的减少;(3)接装纸透气度、滤嘴压降和成型纸透气度对Pb、As、Cd的释放量均有一定影响,但成型纸透气度的影响较小,接装纸透气度、滤嘴压降的影响较为明显。

In order to investigate the effects of different filter parameters on deliveries of Pb, As and Cd in mainstream smoke, the Pb, As and Cd in the mainstream smoke of cigarettes wrapped with filters of different specifications were determined. The results indicated that：（1）Effects of different types of filters on deliveries of Pb, As, Cd in mainstream smoke had certain selectivity.（2）With the increase of the length of the filter, the Pb, As and Cd in mainstream smoke had different decrease.（3）The deliveries of Pb, As and Cd were affected by filter pressure drop and the air permeability of both tipping paper and plug wrapper to a certain extent, however the influence of filter pressure drop and the air permeability of tipping paper was more obvious.
