Measurement and Analysis of Thermal Physical Parameters on Nitrocellulose Energetic Materials
摘要
Abstract
In order to obtain the thermal physical parameters of nitrocellulose (nitrogen content 11.89%~13.5%) to make the thermal analysis calculations and reveal the reaction dynamics mechanism, laser flash method and differential scanning calorimetric (DSC) method were used to measure the thermal physical parameters of nitrocellulose with nitrogen content 12%(NC(12%N)). The values of thermal diffusivity, specific heat capacity, and thermal conductivity were obtained at temperature ranging from 25℃to 140 ℃.Results show that with the increase of temperature, the specific heat capacity increases, while the thermal conductivity and thermal diffusivity decrease.But the changes are not obvious.So these parameters can be determinatal as:in the calculation of thermal analysis:cp =1.131 J・ g-1・ K-1 ,D=0.413 mm2・ s-1 ,λ=0.142 W・ m-1・ K-1 .关键词
