建立了用Ｊｏｕｌｅ效应径向加热与Ｐｅｌｔｉｅｒ效应致冷补偿相结合，在微量热量计上测定含能材料导热系数和热扩散率的装置及方法。利用该装置测定了聚四氟乙烯、有机玻璃、石英玻璃、高密聚乙烯四种标准物质及ＪＨ－９１０５、ＪＯＢ－９００３、ＪＯ－９１５９、ＪＯ－９１８５、ＪＢ－９００１、ＪＯＢ－９００６六种塑料粘结炸药在２９８．２Ｋ下的导热系数及热扩散率，并对实验数据进行了误差分析。四种标准物质的导热系数及热扩散率与文献值的相对误差分别小于０．８％及０．４％。测定不平衡热及径向热流的相对标准偏差分别为０．４％及０．１％，导热系数及热扩散率的测定总相对标准偏差在１．２％以内。圆简体试样内外半径和不平衡热的测量误差是影响导热系数及热扩散率测定准确度的主要因素。
A device and method for measuring the thermal conductivity and thermal diffusivity of energetic materials by using Joule effect radial heating and Peltier effect refrigeration compensation are established. Four kinds of standard materials of polytetrafluoroethylene, organic glass, quartz glass and high density polyethylene and six kinds of plastics such as JH-9105, JOB-9003, JO-9159, JO-9185, JB-9001 and JOB-9006 Thermal Conductivity and Thermal Diffusivity of Bonded Explosives at 298.2K, and Error Analysis of Experimental Data. The relative errors of thermal conductivity and thermal diffusivity of the four reference materials and the literatures were less than 0.8% and 0.4% respectively. The relative standard deviations for the determination of unbalanced heat and radial heat flux were 0.4% and 0.1%, respectively, and the relative standard deviations of the thermal conductivity and thermal diffusivity were within 1.2%. The measurement error of the inner and outer radius and the unbalanced heat of the circular simplified specimen is the main factor that affects the accuracy of the thermal conductivity and thermal diffusivity measurement.
