卷烟纸透气度对卷烟燃吸温度分布特征的影响

Effects of Cigarette Paper Permeability on Temperature Distribution Characteristics in Cigarette During Smoking

为了研究卷烟纸特性对烟支燃烧状态的影响，制备了不同透气度卷烟纸试验卷烟样品，利用改进的Rosin．Rammler（R．R）分布模型考察了40～80CU透气度卷烟纸对卷烟燃吸温度分布特征（燃吸前静燃、抽吸期间和抽吸后）的影响。结果表明：卷烟燃吸过程中，随卷烟纸透气度的增加，燃烧锥最高温度先降低后升高，在透气度为70CU时转折；燃吸过程中各时刻点（静燃、抽吸及阴燃）的燃烧锥体积先增加后降低，在透气度为70CU时转折，同时，燃烧锥体积在抽吸结束时刻达到最大值；燃烧锥特征温度先升高后降低，在透气度为60和70CU时转折，分布参数呈现相同规律。

In order to study the influence of cigarette paper property on cigarette burning state, the effects of cigarette paper permeability （from 40 to 80 CU） on temperature distribution characteristics of cigarette burning （static burning before puffing, puffing and after puffing） were investigated with a revised Rosin-Rammler （R-R） distribution model. The results showed that： in the process of puffing, the highest temperature in burning cone decreased and then raised with the increase of cigarette paper permeability, the lowest value appeared at the permeability of 70 CU; the volume of burning cone increased and then reduced in all of the three burning stages （static burning before puffing, puffing and after puffing）, the biggest volume appeared at the permeability of 70 CU. The volume of burning cone reached its maximum value at the end of smoking, the characteristic temperature and distribution parameter of burning cone raised and then lowered with the turning point at the paper permeability of 60 and 70 CU.
