钾盐消焰剂对推进剂催化剂热分解行为的影响

Effect of potassium salt flame suppressors on the thermal decomposition behavior of the combustion catalysts used in solid propellant

研究了三种不同的钾盐对推进剂用催化剂热分解行为的影响。结果表明 ,有机消焰剂KD对邻苯二甲酸铅 (Φ Pb)的热分解行为影响最小 ,而K3 AlF6的影响程度最大。最后 ,探讨了钾盐对催化剂热分解行为的影响和推进剂平台燃烧效应之间的某些关联。

The effect of different potassium salt on the thermal behavior of the combustion catalysts used in solid propellant is studied.The results show that the organic potassium salt KD has the least effect on the thermal decomposition process of lead phthalate (Φ Pb),and K 3AlF 6 badly influences the decomposition characteristics of Φ Pb.Finally,the relations between the effect of different potassium salt on the thermal decomposition behavior of the burning catalysts and the burning plateau effect of solid propellant are analyzed.
