低爆速膨化铵油爆炸焊接炸药的实验研究
Experimental Study on Expanded ANFO Explosive of Low Detonation Velocity Used in Explosive Welding
摘要
Abstract
In order to solve the problems of poor homogeneity and unstable explosion property of low detonation velocity explosive used in explosive welding. Ammonium nitrate was mixed with microcrystalline, octadecylamine acetate, diluents, and water at 115~125℃, and it was dehydrated at -0.07~-0.09 MPa. The thermal safety, microstructure and mechanical sensitivity were analyzed, the effect of the explosive layout thickness on detonation velocity was also studied, and the explosive welding test on aluminum-steel plate was done. The results show that the component has a good the mixing uniformity, the mechanical sensitivity is low, the detonation velocity is 1900 ~ 2400 m·s-1 , and the recombination rate of ultrasonic flaw detection is up to 99%, which can satisfy the requirement of explosive welding of metal plate.关键词
