催化剂对HMX/AP/HTPB推进剂热分解特性的影响
EFFECT OF CATALYSTS ON THERMAL DECOMPOSITION OF HMX/AP/HTPB PROPELLANT
-
摘要: 热分析实验是使用国产CDR-1型差动热分析仪。热分解活化能用Ozawa法和Kissinger法计算[1],其它动力学参数均用Kissinger法求得。全部热分析实验均在氮气气氛中进行。推进剂燃速用靶线法燃速仪测定。HMX和各种催化剂在使用前均经过烘干处理。催化剂过100目筛。Abstract: The effects of some catalysts on the thermal decomposition of HMX/AP/HTPB propellant are studied with the differential scanning calorimetry(DSC).The experiments demonstrate that the mixture of HMX/AP/=1/1(weight)has specific decomposition characteristics.The catalysts(such as PbO2, Na2S2O8, Fe3O4, CO2O3 and Pb Cr2O4)which are able to increase the burning rate of the propellant,primarily rais6e chemical reaction rate in gaseous phase.
