摘要
为考察卷烟燃吸温度分布对卷烟主流烟气中7种有害成分释放量的影响，研究了由不同助燃剂含量卷烟纸制作的试验卷烟在燃吸过程中的温度分布及其与主流烟气中7种有害成分释放量的相关关系，并建立了相关性模型。结果表明：①卷烟纸助燃剂含量对卷烟主流烟气中CO2苯酚，HCN，NH，和NNK的释放量具有较显著的影响，且均呈现良好的线性相关性，而卷烟纸助剂含量与主流烟气中B[a]P释放量的相关性较差，与巴豆醛释放量无相关性。②在卷烟燃吸过程中，随着卷烟纸助燃剂含量的增加，燃烧锥最高温度降低，而燃烧锥体积增加。③除巴豆醛外，卷烟主流烟气中其他6种有害成分的释放主要集中在250～300℃低温区和650℃以上的高温区。④建立了卷烟燃吸温度加权体积与单口有害成分释放量的相关关系模型，模型预测值和实测值具有显著的线性相关性。
In order to investigate the influence of temperature distribution in burning cone of cigarette on the deliveries of seven harmful components in mainstream cigarette smoke, samples of cigarettes wrapped with cigarette paper containing different percentages of combustion improver were puffed, the temperature distribution in the cigarettes and its relationship with the deliveries of seven harmful components in mainstream cigarette smoke were studied, and their correlation models were established. The results showed that： 1） The content of combustion improver relatively significantly affected the deliveries of CO, phenol, HCN, NH3 and NNK in mainstream cigarette smoke with good linear correlations, but less correlated to B[a]P delivery, and presented no correlation to crotonaldehyde delivery. 2） With the increase of combustion improver content, the maximum temperature in burning cone decreased, while the volume of burning cone increased during puffing. 3） Other than crotonaldehyde, the other six harmful components mainly released from the low temperature zone between 250-300 ℃ and the high temperature zone of above 650 ℃. 4） The correlation models between the temperature distribution in burning cone and the deliveries of the said harmful components per puff were established, and the predicted values were significantly linearly correlated with the measured values.
