【摘要】 为满足非能动型压水堆核电站爆破阀对耐高温产气做功药剂的需求,研制了炭黑/硝酸钾(CPN)推进剂,对其性能进行了测试与评估并与6号黑火药(HY6)和6号无硫黑火药(WHY6)进行了对比。结果表明,CPN推进剂的自动点火温度>321℃,显示CPN推进剂有好的热安定性和耐高温能力。CPN推进剂具有一定的产气做功能力。燃速的排序为CPN推进剂<WHY6<HY6。CPN推进剂摩擦感度和静电感度均为0,安全性优于HY6和WHY6。更多还原

【Abstract】 To satisfy the requirements of passive pressurized water reactor nuclear power station explosion valve for high-temperature-resistant gas-producing powder,the carbon black /potassium nitrate( CPN) propellant was developed,and its performances were tested and evaluated by DSC,TGA,closed bomb test,linear burning rate test,friction sensitivity and electrostatic sensitivity tests. The comparison of performances of CPN and black powder( HY6) and sulfur-free black powder( WHY6) was carried out. Results show that the auto ignition temperature of the CPN propellant is over 321 ℃,revealing that the CPN propellant has good thermal stability and high temperature-resistance ability. The CPN propellant has the ability of producing gas to do work. The burning rates increases in the order; CPN <WHY6 < HY6.The values of friction sensitivity and electrostatic sensitivity of the CPN propellant are 0. The safety of the CPN propellant is better than that of HY6 and WHY6.更多还原
