【摘要】 通过熔点测定仪、红外光谱仪和差热－热重分析仪等现代分析手段对ＮＣ的加热过程进行了研究．提出并证明了ＮＣ存在熔点，以及熔点随着ＮＣ含氮质量分数、粘度和加热速度的变化而变化．更多还原

【Abstract】 The behaviors of nitrocellulose(NC) in condenced phase upon heating were studied using instruments for the determination of melting points of condenced materials,the infrared spectrographs as well as TG-DTA.The fusion temperature of NC is indicated, and the dependence of its melting point on the degree of nitration, viscosity and the rate in the heating of NC is shown.更多还原
