摘要
Abstract
To study the detonation properties of SY under initiation of electric explosion, explosive bridge wires made by Ni-Cr, Al or W were used as energy conversion component to detonate SY columns.Different density, particle size, and addition of components of SY columns were tested to obtain corresponding thresholds of initiation voltage.The re-sults show that larger density or smaller particle size is conducive to detonate.Comparing to density and particle size, the latter has a greater impact on the degree of difficulty.Under the conditions of large density and small particle, SY columns coated with fluororubber are the easiest to detonate by plasma.SY is more sensitive to the Ni-Cr plasma than to W plasma or Al plasma.In addition, small pores of the pillars are more likely to be detonated.关键词
