| 摘 要： | 为揭示卷烟燃烧灰分形成机制，采用色差仪、扫描电镜、能量色散X射线谱仪和红外光谱仪等表征卷烟燃烧灰分不同区域以及不同燃烧热解模拟条件下烟丝和卷烟纸残留物的外观、微观形貌、元素分布及化学组成。结果表明:①卷烟燃烧灰分不同区域外观特征呈多样性。②卷烟燃烧过程中，卷烟纸先发生纤维素降解碳化，颜色由白变黑，随后焦炭燃烧，颜色由深变浅，CaCO3颗粒之间粘聚增大，形成了以Ca、O、K和Na为主的灰分。③燃烧锥内烟丝表面被烧蚀鼓泡，大量脱氧，形成了表面粗糙、含大量褶皱条纹的黑色焦炭，随后焦炭燃烧，多种无机元素富集，颜色由深变浅，烟丝表面形成的高强度泡被烧蚀形成大量孔洞，最后发生无机成分热反应，质量损失较少，颜色更浅，最终形成了含有钙钾镁的氧化物、磷酸盐、硫酸盐、氯化物、硅酸盐和微量有色金属元素的烟丝灰分。

| Abstract: | In order to reveal the formation mechanism of cigarette combustion ash, the appearance, microstructure, element distribution and chemical composition of cut tobacco and cigarette paper residues in different areas of cigarette combustion ash and under different combustion pyrolysis simulation conditions were characterized and analyzed by color difference instrument, scanning electron microscope, energy dispersive X-ray spectrometer and infrared spectrometer. The results show that: 1) the appearance characteristics of cigarette combustion ash in different areas were diverse. 2) In the process of cigarette combustion, the cellulose of cigarette paper was degraded and carbonized first, the color changed from white to black, and then the coke burned, the color changed from dark to light, the cohesion between CaCO3 particles increased, and the ash contents dominated by Ca, O, K and Na were formed. 3) The cut tobacco in the combustion cone was ablated, bubbled and deoxidized in a large amount, forming a black coke with rough surface and a large number of folds and stripes. Then the coke burned, a variety of inorganic elements were enriched, and the color changed from dark to light. The high-strength bubbles formed on the cut tobacco surface were ablated, forming a large number of holes. Finally, the thermal reaction of inorganic components occurred, with less mass loss and lighter color, resulting in cut tobacco ash containing calcium, potassium and magnesium oxides, phosphates, sulfates, chlorides, silicates and trace non-ferrous metal elements. |
