卷烟纸自然透气度对卷烟物理性能及烟气量的影响

为探讨卷烟纸自然透气度对卷烟物理性能及烟气量的影响情况 ,采用国标方法检测了卷烟纸自然透气度分别为 4 0、5 0、6 0、70、80CU时烟支的质量 (g)、圆周、卷烟稀释率、烟支段稀释率、开式吸阻、闭式吸阻、烟气总粒相物、焦油量、烟碱量、一氧化碳量、烟支抽吸口数、静燃速率等 12个理化指标 ,并得到卷烟纸自然透气度与各指标的相关方程。结果表明 ,卷烟纸自然透气度对卷烟的一些物理指标如烟支质量 (g)、圆周、开式吸阻和闭式吸阻影响不大 ,但对卷烟稀释率和烟支段稀释率有影响 ,分别与两者成线性关系 ;卷烟的抽吸口数随卷烟纸自然透气度的增加而减少 ,但当卷烟纸自然透气度超过70CU时 ,卷烟的抽吸口数减少已不明显 ;卷烟的静燃速率随卷烟纸自然透气度的增加而呈上升趋势 ,但增加幅度随卷烟纸自然透气度的增加而减少 ;卷烟烟气中总粒相物、焦油量、烟碱量、一氧化碳量随着卷烟纸自然透气度的增加逐渐减少 ,但当卷烟纸自然透气度超过 70CU时 ,烟气中总粒相物、焦油量的减少已不明显 ,烟气中的烟碱量和一氧化碳量随卷烟纸自然透气度增加基本上呈线性降低。

Influence of Natural Permeability of Cigarette Paper on Physical Properties and Smoke Delivery of Cigarettes

Twelve physical and chemical parameters, such as weight, circumference, dilution ratio, draw resistance, TPM, tar, nicotine, CO, puff number, and static burning rate, of the cigarettes made of cigarette papers with different natural permeability (40, 50, 60, 70, and 80 CU) were determined with the national standard methods. The correlative equations of the natural permeability of the cigarette papers with the parameters were obtained. The results showed that 1) there were hardly any effects of the natural permeability of cigarette paper on the weight, circumference, and draw resistance of cigarettes; 2) The relationships of the natural permeability of cigarette paper with the dilution ratio of tobacco rod were linear; 3) the puff number, TPM, tar, nicotine, and CO were decreased and static burning rate was increased with the increase of the natural permeability of cigarette papers, whereas the changes became not significantly when the natural permeability exceeded 70CU; 4) The reduction of delivery of nicotine and CO was almost linear.
