摘要
为了研究滤纸作为卷烟引燃倾向测试基质的缺陷,探索新的替代基质,测试了不同批次Whatman 2号滤纸的质量、厚度、透气度,卷烟与滤纸存在间距时的全长燃烧百分比,分析了不锈钢基质的底部温度场,比较了标样卷烟SRM1082在不同基质上的全长燃烧百分比。结果表明:①不同批次的滤纸存在差异,卷烟与滤纸的间距会影响引燃倾向测试结果;②0.2 mm厚302不锈钢上附一层滤纸做基质时,标样卷烟的引燃倾向测试结果可以到达SRM1082的标准值(12.6±3.3)%,可以作为引燃倾向测试方法替代基质的主要研究对象。
In a detailed study on the filter papers used as the substrate for testing the ignition propensity of cigarette, the mass, thickness and air permeability of Whatman 2# filter paper of different batches were determined, and the percentage of full length burn （PFLB） of cigarette was determined when a gap was present between cigarette and filter paper. The temperature field at the bottom of a stainless steel substrate was analyzed, and the PFLBs of standard cigarettes SRM1082 on different substrates were compared. The results showed that： 1） There was difference between different batches of filter paper, the distance between cigarette and filter paper affected the test result of PFLB; 2） The test results of standard cigarette sample reached the standard value of SRM1082 （12.6%±3.3%） when one layer of filter paper on a 302 stainless steel plate of 0.2 mm in thickness was used as a substrate, it provided a clue to the study of alternative substrate for testing ignition propensity of cigarette.
