卷烟纸参数对细支卷烟燃烧锥落头倾向的影响

Effects of cigarette paper parameters on combustion coal fallout propensity of burning slim cigarettes

选取不同参数(定量、透气度、麻浆质量分数、灰分质量分数、助燃剂质量分数、助燃剂中钾盐占比等)的卷烟纸制作细支卷烟样品,考察卷烟纸性状对细支卷烟燃烧锥落头倾向的影响,并对参数设置进行优化.结果表明:细支卷烟的燃烧锥落头倾向随卷烟纸定量的增大而迅速降低;卷烟纸的透气度、麻浆质量分数和灰分质量分数的增大均引起细支卷烟燃烧锥落头倾向的显著上升,其中卷烟纸的透气度与燃烧锥落头倾向正相关;助燃剂质量分数的变化对降低燃烧锥落头倾向无显著效果,但助燃剂中钾盐占比过高则会引起燃烧锥落头倾向的迅速增大;对细支卷烟燃烧锥落头倾向的影响大小依次为透气度>定量>助燃剂中钾盐占比>助燃剂质量分数,卷烟纸最优参数组合为透气度50 CU,定量34 g·m-2,助燃剂中钾盐占比50%,助燃剂质量分数1. 5%,在该参数设置下,燃烧锥落头倾向由优化前的6. 3%降至2. 5%.

In order to investigate the effects of cigarette paper properties on the combustion coal fallout propensity of burning slim cigarette,cigarette paper with different parameters(grammage,air permeability,hemp pulp content,ash content,burn promoter content and proportion of potassium salts in burn promoter)was selected and the samples of fine cigarette were made.The parameters were set optimization.The results showed that the combustion coal fallout propensity of slim cigarettes decreased rapidly with the increase of paper grammage.The presence of air permeability,hemp pulp content and ash content in cigarette papers was able to promote the fallout propensity of combustion coal,in a content-dependent manner.Meanwhile,air permeability of cigarette paper exhibited a positive correlation to the combustion coal fallout propensity.The change of burn promoter content had no significant effect on reducing the tendency of the fallout propensity of combustion coal,while the excessively high proportion of potassium salts in burn promoter would cause the tendency of the fallout propensity of combustion coal to fall rapidly.The four parameters of air permeability,grammage,burn promoter content and proportion of potassium salts in burn promoter were sorted in descending order of the influence on the combustion coal fallout propensity as below:air permeability>grammage>proportion of potassium salts in burn promoter>burn promoter content.The combustion coal fallout propensity decreased from 6.3%to 2.5%with the optimum cigarette paper parameters of air permeability 50 CU,grammage 34 g·m-2,proportion of potassium salts in burn promoter 50%,burn promoter content 1.5%.
