卷烟纸特性对卷烟静态包灰性能的影响

Effects of cigarette paper property on ash cohesion of statically burning cigarette

  • 摘要: 为研究卷烟纸特性对卷烟静态包灰性能的影响,采用层次分析法确定卷烟包灰持灰力、白度、裂口率、缩灰率、碳线整齐度5个指标的权重,建立了定量评价卷烟包灰综合性能的方法。结果表明:①各指标的权重分别为W持灰力=0.04,W白度=0.16,W裂口率=0.64,W缩灰率=0.10,W碳线整齐度=0.06,权重判断矩阵通过一致性检验(CR=0.081 < 0.1),说明计算的权重较准确。②利用构建的评价方法分析卷烟纸特性对包灰综合性能的影响,定量结果与静燃实际包灰效果具有一致性,说明该评价方法较可靠。③对于不同的有机酸钾助燃剂,其包灰综合性能:酒石酸钾>醋酸钾>柠檬酸钾。钾钠比为1:1时,随着柠檬酸根含量的增加,包灰综合性能提升。较低的钾钠比、较高的氧化钙灰分含量、较高的透气度对提升包灰综合性能均有作用。

     

    Abstract: In order to study the properties of cigarette paper on ash integration and cohesion of static burning cigarettes, an experimental method was developed to determine the weights of ash holding, whiteness, crack rate, ash shrink rate and burn line uniformity with analytic hierarchy process (AHP). The results showed that:1) The weights of ash holding, whiteness, crack rate, ash shrink rate and burn line uniformity were 0.04, 0.16, 0.64, 0.10 and 0.06 respectively. The ash weight decision matrix passed the consistency test (CR=0.081 < 0.1), indicating that the calculated ash weights were accurate. 2) The developed method was used to analyze the properties of cigarette paper on the comprehensive cigarette ash integration and the quantitative results agreed with the actual ash integration of static burning cigarettes, suggesting that the developed method was reliable. 3) The order of effectiveness for comprehensive cigarette ash integration were potassium tartrate > potassium acetate > potassium citrate. With the increase of citrate content, comprehensive cigarette ash integration improved significantly at the potassium/sodium ratio of 1:1. A lower potassium/sodium ratio, higher calcium oxide content and higher air permeability were beneficial to the improvement of comprehensive cigarette ash integration.
