摘要(Abstract):

利用C80微热量热仪研究了分析纯硝酸铵、典型配方的乳化炸药基质以及含有高氯酸铵(AP)的乳化炸药基质的热分解过程。通过C80热流曲线所得出的结果,采用单一非等温曲线法,求出了相应的动力学参数。结果表明:AP不但可以消弱AN晶变的热效应,而且具有稳定AN晶型的作用;AP对乳化炸药基质的热分解具有一定的催化作用,但催化作用不显著。
Thermal decomposition processes of ammonium nitrate with analytical pure grade,the emulsion explosive matrix with the typical formulations and with adding Ammonium perchlorate were studied by C80 micro calorimeter.With the single non-isothermal curve method,the kinetic parameters by the results of C80 heat flow curve were obtained.Results indicated that ammonium perchlorate could slack down the thermal effects of the crystal transition of ammonium nitrate,and stabilize polymorphs of ammonium nitrate;ammonium perchlorate had a certain catalysis action to the thermal decomposition of emulsion explosive matrix,but it was not obvious.
