梗丝与膨胀丝及薄片丝对卷烟主流烟气中3种有害成分释放量的影响

Effects of stem wire,expansion wire and flake wire on 3 harmful components in mainstream cigarette smoke

采用正交试验方法,用掺配不同比例"三丝"(梗丝、膨胀丝及薄片丝)的烟丝(不加香)卷制烟支,测定卷烟主流烟气中3种有害成分(NH3,HCN,CO)的释放量。结果发现:以烟气NH3释放量为主要考虑因素时,梗丝、膨胀丝和薄片丝最优掺配比例分别为15%、15%和15%;以烟气HCN释放量为主要考虑因素时,梗丝、膨胀丝和薄片丝最优掺配比例分别为15%、5%和15%;以烟气CO释放量为主要考虑因素时,梗丝、膨胀丝和薄片丝最优掺配比例分别为15%、15%和0%。

Orthogonal test was used to make cigarette （no flavor） using cut tobacco added with different proportions of three kinds of wires （stem wire, expansion wire and flake wire）, and the contents of 3 harmful components （NH3, HCN, CO） released in mainstream smoke of cigarettes were determined. The results indicated that when mainly considering the cigarette smoke emission of NH3, the optimum proportions of stem wire, expansion wire and flake wire were 15%, 15% and 15% respectively; when mainly considering the cigarette smoke emission of HCN, the optimum proportions of stem wire, expansion wire and flake wire were 15%, 5% and 15% respectively; when mainly considering the cigarette smoke emission of CO, the optimum proportions of stem wire, expansion wire and flake wire were 15%, 15% and 0% respectively.
