SETSYS STA超高温同步热分析

• The temperature of the calorimeter is maintained at 70°C. • Batteries of type CR1220 are studied. • 9 batteries are superimposed inside the vessel. • Between two batteries a layer of paper is inserted to insulate electrically the batteries from each other.

TGA 经常用于测定聚合物、生物燃料、化学品、制药品和其他材料的水分和挥发物含量。控制这些材料的水分和挥发物含量很重要，因为它可能影响它们的性质、质量和安全性。在这里，使用 SETLINE TGA 测定了尼龙 6,6 的水分和挥发物含量。

发泡剂 H广泛应用于橡胶发泡，其生产工艺属于亚硝化工艺，是重点监管的危险化工工艺，因此，对发泡剂 H的工艺热危险性分析是很有必要的。利用量热仪器可以对物质的热稳定性进行研究。差示扫描量热仪(DSC)便是其中之一。

二硝酰胺铵(ADN)是一种新型氧化剂，它具有能量高、成气量大、含氧量较高、燃气清洁、毒性小、环境友好等特点，用其取代高氯酸铵(AP)能提高推进剂的能量，降低燃气羽焰的特征信号。因此，ADN 在推进剂中具有良好的应用前景，许多国家都致力于研究含 ADN 的适宜推进剂配方体系。其中，ADN 与黏合剂的相容性研究是 ADN 在推进剂中应用的基础

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 The results are compared to both published and unpublished previously determined smaller data sets.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.
