摘要
采用6.0Y/17000规格丝束制备了不同滤嘴参数(滤嘴通风率、滤棒压降)的细支烟样品,并考查了滤嘴参数对其主要理化指标(烟支吸阻、烟碱过滤效率、焦油释放量、烟碱释放量、CO释放量、主流烟气pH值)及感官品质的影响。结果表明:烟支吸阻与滤棒压降正相关,与滤嘴通风率负相关,相同的滤棒压降变化,细支烟烟支吸阻的变化幅度约为常规烟的1/2,相同滤嘴通风率变化,细支烟烟支吸阻的变化幅度约为常规烟的1.7倍。细支烟滤嘴对烟碱的过滤效率与滤棒压降和滤嘴通风率均正相关,且过滤效率低于常规烟。焦油、烟碱的释放量与滤嘴通风率和滤棒压降均显著负相关,且滤嘴参数变化对细支烟常规成分的影响幅度低于常规烟。细支烟主流烟气中CO的单位焦油释放量随滤嘴通风率的增加而减小,烟碱的单位焦油释放量随滤嘴通风率的增加而增加。分别建立了个理化指标与滤嘴参数的回归方程,预测精度良好。细支烟感官评价得分随滤棒压降的增加而降低,随滤嘴通风率的增加呈先升高后降低的趋势,滤嘴通风率设定为40%时感官品质最优。
Slim cigarette samples with different filter parameters(filter ventilation and filter rod pressure drop)were prepared with 6.0Y/17000 tow,and the effects of filter parameters on its main physical and chemical indexes(cigarette draw resistance,nicotine filtration efficiency,tar release,nicotine release,CO release,mainstream smoke pH)and sensory quality were investigated.The results showed that the cigarettes draw resistance showed a positive correlation with filter rod pressure drop,and a negative correlation with filter ventilation,changing the same filter rod pressure drop,the change range of slim cigarette draw resistance was about 1/2 that of conventional cigarette,changing the same filter ventilation,the change range of slim cigarette draw resistance was about 1.7 times that of conventional cigarette.The filter efficiency of slim cigarette for nicotine had positive correlation with the filter rod pressure drop and the filter ventilation and the filtration efficiency of slim cigarette was lower than that of the conventional cigarettes.The deliveries of tar and nicotine had negative correlation with filter rod pressure drop and filter ventilation,and the influence of filter parameters on slim cigarette was lower than that of conventional cigarette.The unit tar release of CO in mainstream smoke of slim cigarette decreased with the increase of filter ventilation,while the unit tar release of nicotine increased with the increase of filter ventilation.The regression equations of cigarette draw resistance,nicotine filtration efficiency,tar,nicotine,CO and mainstream smoke pH and filter parameters were established respectively,and the prediction accuracy of the model was good.Cigarette sensory evaluation score decreased with the increase of filter rod pressure drop,and increased at first then decreased with the increase of filter ventilation,the sensory quality was the best for slim cigarettes with 40%filter ventilation.
