导爆管新型成套引爆器具研制成功辽宁省营口市高能爆破仪表研究所，在市场导爆管引爆火帽供应短缺的情况下，通过科学实验，研制了特种高效火帽和新型激发器具引爆装置。由于这种火帽，前端具有褶皱形收口，它会产生聚能作用，故较传统的任何一种火帽发火效率都好。另外一... Detonating tube new complete sets of detonators successfully developed Yingkou City, Liaoning Province, high-energy blasting instrumentation Institute, in the market detonating cap supply shortage of cases, through scientific experiments, developed a special high-efficiency fire cap and a new type of ignition device detonator. Because of this cap, the front has a pleat-shaped mouth, it will have a role in energy gathering, it is more efficient than any of the traditional fire-cap firing efficiency. Another one ...
