微胶囊对卷烟纸阴燃速率和阴燃温度的影响

本实验分析空心微胶囊粉末、茉莉香精微胶囊粉末和酸梅香精微胶囊粉末及其用量对卷烟纸透气度、阴燃速率和阴燃最高温度的影响。结果表明,随空心微胶囊粉末和酸梅香精微胶囊粉末用量增加,卷烟纸透气度逐渐降低,茉莉香精微胶囊对卷烟纸透气度基本没有影响;当微胶囊用量为2. 0%时,与对照样相比,空心微胶囊粉末对卷烟纸阴燃速率提高9. 4%,另外2种微胶囊对卷烟纸阴燃速率基本相同,且微胶囊囊芯香精的燃烧性也对燃烧速率有影响;当微胶囊用量超过1. 5%时,随微胶囊用量提高,卷烟纸阴燃最高温度升高。

Effects of Microcapsules on Smoldering Rate and Burning Temperature of Cigarette Paper

In this Paper the effects of microcapsules and its dosages, including hollow microcapsule, jasmine flavor microcapsule and cranberry flavor microcapsule in cigarette paper on permeability, smoldering rate and maximum smoldering temperature of the paper were studied. The results showed that the air permeability of cigarette paper decreased gradually with the increase of the amount of hollow microcapsule and cranberry flavor microcapsule. The air permeability of cigarette paper was not affected by jasmine flavor microcapsule. When the dosage of microcapsule was 2.0%, compared with the control, the smoldering rates of cigarette paper adding hollow microcapsule increased by 9.4%, and the smoldering rates adding cigarette papers adding was almost the same. Besides the dosage, combustibility of microcapsule flavorcore also has an effect on the burning rate. When the dosage of microcapsule was more than 1.5%, the maximum smoldering temperature of cigarette paper increased with the dosage.
