摘要:
针对持续高温暴露、烤爆环境以及油气深井开采中应用的火工品对耐高温起爆药的需求,合成、评估了新型起爆药叠氮化镉。利用复分解反应研究了叠氮化镉的合成方法与工艺,通过成分、IR分析对叠氮化镉的结构进行了表征和确认。对叠氮化镉的热、感度、爆速、起爆能力等性能进行评估,叠氮化镉分解温度比叠氮化铅高,分解峰达到334~370 ℃,爆炸温度达到417~426 ℃;叠氮化镉撞击感度相当于叠氮化铅,而摩擦感度、静电感度比叠氮化铅钝感。叠氮化镉是一种优良的耐高温起爆药,可以代替叠氮化铅用于军用耐高温雷管、深井石油开采爆破装置以及工程雷管中。
Abstract:
For the demand of resisting high temperature of primary explosives used in initiator at sustained high temperature exposure, coke off environment and oilgas well exploitation, a new primary explosive cadmium azide (CA) had been synthesized and evaluated. Synthesis techniques of CA have been studied by metathesis reaction. The structure characteristic of CA has been measured by the component analysis and IR spectrum. By the evaluation of its properties such as heat, sensitivity, explosion speed and initiating ability, it is considered that the decomposing temperature of CA (334~370℃) is higher than lead azide, and its blast temperature is up to 417~426℃. The impacting sensitivity of CA is similar to lead azide, but the friction and static sensitivity of CA are lower than those of lead azide. The results show that CA is a primary explosive resisting high temperature, serving as a substitute of lead azide that could be used in military and civil detonators.
