纳米延期药的研制

Study on Nano-Material Delay Composition

文章通过对延期药粒子结构模型的分析,找出了延期药燃烧不稳定和秒量飘移的原因,应用纳米添加剂研制了纳米延期药,其燃烧精度高,秒量稳定,雷管自然贮存1年后秒量变化不超过5%。

By analyzing particle structure model of delay composition, the reason of unstable burning and delay time changing of delay composition are found out in this paper. The nano-material delay composition with higher burning precision and more stable delay time is produced by adding nano-material additives, the change in delay time of detonator is no more than 5% after one year under natural condition.
