聚能炸药索是一种内装炸药、带有V型槽的金属管,又名切割索。它的工作原理是在炸药起爆后,一部分能量沿爆轰波方向传播,另一部分能量作用在聚能罩上,使聚能罩的内层金属粒子高速碰撞,以获得高速动能。这样,爆炸产物与金属粒子就在一定方向上产生一股高速、高压、呈薄层状的射流。这股射流能切割铝板、钢板等金属材料。
Poly explosive cable is a built-in dynamite, with a V-groove metal tube, also known as cutting cable. Its working principle is that after the explosive is detonated, part of the energy propagates along the detonation wave direction and the other part of the energy acts on the energy concentrating cover, so that the inner metal particles of the energy concentrating cover collide at high speed to obtain high-speed kinetic energy. In this way, the explosive product and the metal particles produce a high velocity, high pressure, thin layer jet in a certain direction. This jet can cut aluminum, steel and other metal materials.
