摘要:考察了不同有机酸金属盐(柠檬酸钾、乙酸钾、草酸钾、酒石酸钾、柠檬酸钠、柠檬酸钠/柠檬酸钾(质量比1∶1)混合物)对卷烟纸热解特性的影响,通过扫描电子显微镜及热重/差热分析初步探讨了有机酸金属盐对卷烟纸热解的影响机理。结果表明,以上6种有机酸金属盐均有助于卷烟纸热解并产生致密孔隙,加速烟气扩散,促进CO排出;钾盐对降低卷烟纸热解所需活化能的效果最好,钾含量越高,卷烟纸越易在较低温度下发生热解反应。
Abstract:The effects of different organic acid metal salts (potassium citrate, potassium acetate, potassium oxalate, potassium tartrate, sodium citrate, and the mix of sodium citrate and potassium citrate (mass ratio of 1:1) mixture) on the pyrolysis characteristics of cigarette papers were investigated. The mechanism of the influence of organic acid metal salts on the pyrolysis of cigarette paper was studied via scanning electron microscope and thermogravimetric/differential thermal analysis. The results showed that the above 6 kinds of organic acid metal salts all contributed to the pyrogenation of cigarette paper and produced dense pores, accelerated the diffusion of smoke and promoted the emission of CO. Potassium salts were the best organic acid metal salts for reducing the activation energy required for pyrolysis of cigarette paper. The higher the potassium salt content, the easier the pyrolysis reaction of cigarette paper occured at low temperature.
