切丝宽度对卷烟烟丝结构和主流烟气的影响

Influence of cutting width on cut tobacco structure and mainstream smoke

为比较不同切丝宽度对卷烟主流烟气中7种有害成分释放量和卷烟烟丝结构的影响，对两种低焦油规格的卷烟进行切丝宽度试验，分析不同切丝宽度对7种有害成分释放量及烟气危害性指数的影响，并对烟丝结构与烟气危害性指数进行相关分析．研究表明：切丝宽度对卷烟烟气中有害成分的单支和单口释放量均有一定影响；烟丝长度与烟气危害性指数有正负相关性，两种规格卷烟应适当增加3．35～2．00mm长度的烟丝比例．

For comparisons effect of different cutting width, cigarette tobacco structure and the emission of seven harmful components in mainstream smoke was investigated, the width of cutting test for two kinds of specifications of low tar cigarette was proceeded, the different width of cut tobacco in 7 kinds of harmful ingredients release amount and smoke hazard index of effect was analysis. The results shows that width of cutting of two specifications cigarette should be controlled in the range of 3.35-2.00 mm, which consist in positive and negative correlation with hazard index.
