细支卷烟燃烧锥落头倾向的影响因素

Factors influencing combustion cone falling propensity of slim cigarettes

为研究细支卷烟燃烧锥落头倾向的影响因素,采用自行研发的卷烟燃烧锥落头倾向测试仪和测试方法,对细支卷烟燃烧锥落头倾向进行评价,分别从单因素角度考察了细支卷烟烟支单支质量、卷烟纸助燃剂含量、烟丝含水率和烟丝中梗签含量4个因素对细支卷烟燃烧锥落头倾向的影响规律。采用偏最小二乘法(PLS)考察了4个因素对细支卷烟燃烧锥落头倾向影响的显著程度。结果表明:①细支卷烟燃烧锥落头倾向随烟支单支质量减小而急剧增加,随卷烟纸助燃剂含量增加而有较大程度的增加,随烟丝含水率的降低而明显增加,随烟丝中梗签量的增加而略有增加。②所考察的4个因素与细支卷烟燃烧锥落头倾向线性关系显著,烟支单支质量对细支卷烟燃烧锥落头倾向影响最大,其次分别是卷烟纸助燃剂含量、烟丝含水率、烟丝中梗签含量。③在某品牌卷烟生产过程中借鉴上述研究结果,适当提高烟支单支质量,卷烟燃烧锥落头倾向明显降低。

To study the factors influencing the combustion cone falling propensity(CCFP)for slim cigarettes,lit slim cigarettes were assessed via an in-house developed CCFP instrument and associated test methods.Four factors(cigarette weight,combustion promoter content in cigarette paper,moisture and stem contents in cut tobacco)on the CCFP of slim cigarettes were investigated through single-factor experiments,and results were analyzed by partial least square method(PLS).The results showed that:1)The CCFP of slim cigarettes sharply increased with the decrease of cigarette weight,greatly increased with the increase of the combustion promoter content in cigarette paper.It also clearly increased with the reduction of the moisture content in cut tobacco and slightly increased with the increase of the stem content in cut tobacco.2)The linear relationships between the four factors and the CCFP of slim cigarettes were significant.The effect of cigarette weight was the greatest,followed by the combustion promoter content in cigarette paper,the moisture content and the stem content in cut tobacco.3)By applying the above knowledge,the CCFP of a commercial slim cigarette was significantly reduced via increasing the cigarette weight during manufacturing.
