“原位”合成铜叠氮化物的爆速测试

Measurement of Detonation Velocity of Copper Azides Prepared by 'In Situ' Method

为了测试铜叠氮化物的爆速,采用多层叠片装药方式制成长药柱,将镀在约束壳体表面的细金属线用作特殊的探针,测试了两种装药直径(0.8mm、1.0mm)下的爆速。测试结果表明:采用该特殊探针测试铜叠氮化物装药爆速的结果一致性好;当装药厚度达到0.9mm时,铜叠氮化物已经达到稳定爆轰状态;装药直径为1.0mm时的平均爆轰速度为5 317 m·s^(-1),大于装药直径为0.8mm时的平均爆轰速度5 229 m·s^(-1)。

Aimed at measuring the detonation velocity of copper azides, the long grain was fabricated by piling up multi-charges, the thin metal wire deposited in confinement surface was used for a special probe, and the detonation velocity of charges with two diameter was tested. The results indicate that the measurement results are of good consistency through using this special probe, and copper azides have reached the stable detonation state when the charge length is 0.9 mm. The average detonation velocity of 1.0 mm charge diameter is larger than that of 0.8mm charge diameter, which are 5 317 m·s^-1 and 5 229m·s^-1 respectively.
