Data from: Gap initiation with 20.35 mm: an initiator integrating the Al/CuOx multilayer film and traditional electronic plug to enhance the ignition ability

IIn order to enhance the ignition ability and reliability of traditional electronic initiators, a novel electronic initiator has been designed to integrate with a nanothermite multilayer film and an electrode plug. The Al/CuOx nanothermite multilayer film with different thickness is deposited on the surface of electrode plug by magnetron sputtering which used Pt-W wire as electronic resistance. The exothermicity of Al/CuOx nanothermite multilayer film is so favorable that the ignition ability of electronic initiator is significantly improved. The fully firing-voltage sensitivity of the electronic initiator is 10.8 V. The thickness of Al/CuOx multilayer film has negligible effects on the ignition time and ignition energy, but leads to great impacts on the function time, the maximum length of combustion flame and ignition ability. The electrical ignition experiments have exhibited outstanding ignition ability, since the electronic initiator can easily fire the insensitive ignition composition of boron-potassium nitrate (B-KNO3) tablet in a gap of 20.35 mm. It proves that this novel propose of remolding the tradition electronic ignition devices will distinctly improve the ignition ability and reliability of electronic initiator.为提升传统电子起爆器（electronic initiator）的点火能力与可靠性，本研究设计了一款集成纳米铝热剂多层膜（nanothermite multilayer film）与电极插头的新型电子起爆器。以铂-钨（Pt-W）丝作为电子电阻，通过磁控溅射（magnetron sputtering）法在电极插头表面沉积了不同厚度的Al/CuOₓ纳米铝热剂多层膜。该Al/CuOₓ纳米铝热剂多层膜具备优异的放热性能，可显著提升电子起爆器的点火能力。该电子起爆器的全发火电压灵敏度为10.8 V。Al/CuOₓ多层膜的厚度对点火时间与点火能量的影响可忽略不计，但对作用时长、燃烧火焰最大长度以及点火能力存在显著影响。电点火实验展现了优异的点火性能：该电子起爆器可在20.35 mm的间隙中轻松引燃钝感的硼-硝酸钾（B-KNO₃）药柱。研究证实，这种对传统电子点火装置的改造方案，可显著提升电子起爆器的点火能力与可靠性。
