烟草及烟叶中热物性分析检测方案(同步热分析仪)
The values of the thermophysical properties of tobacco and other cigarette components are important input parameters for cigarette combustion models [1-7] and tobacco process design and characterization. Knowledge of these values is also essential to the development of cigarette prototypes with modified burning characteristics. Heat capacity, thermal diffusivity and thermal conductivity are key parameters. An understanding of these thermophysical properties for substrates in contact with a burning cigarette is essential for understanding cigarette related fire scenarios. Work in these areas has been reported by tobacco companies as well as government agencies [8-10] . Data have been reported for the heat capacities [5, 11-14] and thermal diffusivities [5, 14-16] of tobacco but relatively little information exists with regard to thermal conductivity[5] . In this paper we present the thermal conductivity and thermal effusivity values determined for an extensive set of tobaccos as well as cigarette paper and filter tow. The tobacco types include bright, burley, reconstituted sheet materials and blends. The results are compared to both published and unpublished previously determined smaller data sets. The available heat capacity data are reviewed. The results suggest that most biomass materials behave similarly with regard to thermophysical properties.
