| 摘 要： | 为了获得六硝基芪的烤燃响应特性,对六硝基芪进行了非限制条件下的程序升温烤燃试验.结果表明,随着升温速率的增加,HNS的起始反应温度呈升高的趋势.3.3℃/h升温速率下3种尺寸的HNS药柱只发生热分解反应,且反应后发现大量黑色残留物.在5℃/min和10℃/min条件下药柱发生燃烧或不完全燃烧反应,均没有发生爆炸现象.几...

| Abstract: | In order to obtain the cock-off response properties of HNS,the cook-off tests of HNS cylinder used in exploding foil initiator under nonrestrictive condition were carried out with various temperature increasing rates.The results show that the initial reaction temperature takes on the increscent trend with increasing heating rate.The HNS explosive cylinders of three sizes just decomposed at a heating rate of 3.3℃/h,and black remain was obtained.While no explosion phenomena turned up under the heating rate of 5℃/min and 10℃/min,the explosive was just burned or incompletely burned.The surface temperature of HNS at ignition point was from 328 to 335℃.The reaction intensity went up as the charge weight and temperature rate increasing.Execrable thermal environment will cause that part of the explosive reach the critical temperature.The HNS explosive cylinder of a small charge is safe under heat stimulation. |
