通风分配对常规和细支卷烟主流烟气pH影响分析
Effects of ventilation distribution on mainstream smoke pH of regular and slim cigarettes
摘要
Abstract
[Objective]To investigate the effects of ventilation rate and ventilation distribution on the mainstream smoke pH of cigarettes.[Methods]The total particulate matter of mainstream smoke was extracted with water at pH 7.000,the smoke pH of regular and slim cigarettes under different ventilation distributions was determined using a pH meter.[Results]①With increasing total ventilation rate,the smoke pH of both regular and slim cigarettes increased linearly(R2＞0.93),and the increase of smoke pH from regular cigarette was greater than that of slim cigarette.②Prediction models correlating smoke pH with filter ventilation and cigarette paper ventilation were established and validated,the ratio of the predicted value to the measured value of cigarette smoke pH is between 1.001 and 1.004,indicating that the established prediction model has high adaptability.And whether it was regular cigarette or slim cigarette,all model coefficients were positive,indicating that smoke pH increased with either cigarette paper ventilation or filter ventilation.③Under the premise of fixed total ventilation of cigarettes,the ratio Vp/Vf has a greater effect on the mainstream smoke pH of regular cigarettes than on that of slim cigarettes.[Conclusion]Under the premise of fixed total ventilation of cigarettes,there are significant differences in the ventilation distribution strategies for regulating mainstream smoke pH between regular and slim cigarettes.关键词
