【摘要】 通过90℃高温加速老化试验,分别研究了DNTF在失重0.25%、0.50%、0.75%、1.0%时物理化学性能的变化,结果表明,在加速老化过程中,DNTF熔点、分解温度、晶体形貌没有发生明显的变化,但是摩擦感度和撞击感度分别升高到96%、84%,这将对DNTF的安全贮存和安全使用产生不利影响。更多还原

【Abstract】 The physical and chemical properties of DNTF at mass loss 0.25%, 0.50%, 0.75%, 1.0% were researched in 90 ℃high temperature accelerated aging process. The results showed that the melting point, decomposition temperature, crystal morphology of DNTF had no significant change in accelerated aging process. But friction sensitivity and impact sensitivity of aged DNTF were up to 96% and 84% respectively, which would adversely affect the safe storage and use of DNTF.更多还原
