文中为了研究电点火头在长期储存后药剂和桥丝的变化情况 ,对电点火头进行了高温高湿加速寿命试验 ,并对点火头药剂的红外吸收光谱进行对比分析 ,结果表明 ,经加速寿命试验的点火头药剂受温度和湿度的影响大部分发生了分解。显微镜观察表明桥丝表面腐蚀严重。 In this paper, in order to study the changes of electrical ignition head after long-term storage of medicine and bridge wire, the electric ignition head was accelerated life test at high temperature and high humidity, and comparative analysis of infrared absorption spectrum of ignition head agent showed that the accelerated life Most of the tested ignition head chemicals were decomposed due to temperature and humidity. Microscopic observation showed that the bridge wire surface was seriously corroded.
