摘要
为研究酸性乙炔银作为光敏炸药用于模拟X射线热-力学效应的可行性,开展了酸性乙炔银涂层的闪光起爆性能研究。根据酸性乙炔银的基本性能和实验测定的感度,分析其光起爆作用机制,开展了酸性乙炔银涂层的爆轰性能测试,并实现了高压脉冲闪光条件下的大面积起爆。研究结果表明:酸性乙炔银是一种相对安全的光敏感炸药,在喷涂层表面的爆轰传播速度较低,可作为低过载瞬态加载源使用;在低密度条件下,其爆炸比冲量与喷涂层的面密度近似呈线性关系。
To investigate the feasibility of applying the light-initiated explosive, silver acetylide-silver nitrate （SASN） ,as an effective simulation of a cold X-ray blow-off event,we carried out experimental researches on the detonation property of SASN ignited by a light flash. First we presented the basic and sensitivity character- istics of SASN, and then based on the analysis of its light-initiated mechanisms, we succeeded in igniting a large area of SASN sprayed layer by a light flash with high voltage, and conducted tests on the detonation characteristics of SASN sprayed layer initiated by light. The results indicate that SASN is a relatively safe agent of light-sensitive explosive with a relatively low detonation velocity of sprayed layer capable of providing low impulsive loads. The test results confirmed that linear to the areal density of sprayed layer under the the specific impulse of explosion from SASN is almost conditions of low-level density.
