摘要
利用扫描电镜、广角X-射线衍射仪和热重分析仪比较了几种烟丝的表面形态、断面形态、结晶结构与热稳定性的差异,结果表明:天然烟丝组织干瘪,排列紧密,膨胀丝组织光滑膨大;天然烟丝中纤维素结晶度高,膨胀丝中纤维素结晶度较低;3种烟丝热稳定性差别不大。
Data of morphological,structural and thermal stability of three different cut tobaccos were obtained by SEM,WAXD and TGA metods.Results showed that the structure of natural tobacco was tight and hence limited filling power,while the structure of expanded tobacco was smooth and hence improved filling power.The crystallization of cellulose in natural tobacco was higher than that in expanded tobacco.The thermal stability of the three tobaccos were similar.
