卷烟纸参数对卷烟自由燃烧速率的影响

Effects of Cigarette Paper Parameters on Free Combustion Rate of Cigarette

卷烟自由燃烧速率是卷烟燃烧特性的表观特征参数,实验考察了卷烟纸的原料组分、定量、透气度、灰分、宽度及助燃剂等参数对卷烟自由燃烧速率的影响,并分析了卷烟纸阴燃速率与卷烟自由燃烧速率间的关联性,结果表明:卷烟纸的定量、透气度、助燃剂含量以及助燃剂中钾盐和钠盐的比例是影响卷烟自由燃烧速率的主要卷烟纸参数,而卷烟纸浆料组分、灰分以及宽度对卷烟自由燃烧速率影响有限;卷烟纸阴燃速率仅反映卷烟纸自身的燃烧性,与卷烟自由燃烧速率无明显相关性.

The rate of free combustion of cigarette represents apparent characteristic parameters of cigarette combustibility.The influence of different cigarette paper parameters,such as basis weight,air permeability,K/Na ratio,hemp pulp content,ash content and burn improver content,was studied.The results showed that four cigarette paper parameters,including basis weight,permeability,combustion improver content and K/Na ratio,significantly promoted the rate of free combustion of cigarette.Whereas hemp pulp content,ash content and cigarette paper width had no obvious influence.Moreover,cigarette paper smoldering rate only reflected its combustibility and has no significant correlation with free combustion of cigarette.
