摘要射钉技术主要应用于建筑、水工、暖通领域，是一项非常具有市场前景的紧固技术。目前市场上射钉弹大多由撞针击发，并没有出现射钉弹的电点火技术，而射钉弹的电点火又具有可靠性高，能长时间连续工作的优点，因此本课题就是研究基于射钉弹击发药的电点火技术。通过叠氮肼镍起爆药以及BTTA点火药包覆碳晶膜电点火桥，通过电容激发以及恒流激发，探究其对不同配方击发药片的点火能力，并测试其点火参数。通过比较可知道，碳晶膜电点火桥的包覆药剂应该具有能量高，作用迅速的特点，叠氮肼镍起爆药满足需求，而BTTA点火药则因响应感度低并不能满足需求。由实验数据可得，只要碳晶膜电点火桥包覆材料的能量足够高，作用足够迅速，则点火电压及电流与击发药的配方没有关系；反之，若碳晶膜包覆药剂并不能满足以上要求，则会出现击发药片燃烧或者无法点火的情况。77890

Title    Electric ignition technology on the pieces of primer                                                 

Abstract Nail technology is mainly used in woodworking, architecture, and it is a very promising fastening technology。 Currently on the market the nail bomb fired almost is by needle, and no nail electric ignition technology and nail bombs appears。 Bombs’ electric ignition, has the advantages of high reliability and long-time-continuous work。 Therefore, this topic is to study the nail bomb primer electric ignition technology。 Based on the nickel hydrazine NHA explosive ignition and BTTA cladding carbon crystal film electric ignition bridge, and constant current through the capacitor firing way to explore their different formulations of firing tablets and test the ignition energy, ignition parameters。 By comparing know, the carbon crystal film coating agent electric ignition bridge should have characteristics of high energy, fast acting, nickel hydrazine NHA explosive to meet the demand, while the BTTA powder and can not meet the demand。 By the experimental data available, as long as the carbon film electric ignition bridge Coating material energy is high enough, quickly enough, the ignition voltage and current and firing drug formulations without relationship; on the contrary, if the amorphous carbon film coating agent and does not meet the above requirements, firing pill combustion or unable to be ignited。
