防射频高钝感电雷管的制备与性能OA

In order to improve the anti radio frequency and current insensitive performances of electric detonators,based on ordinary industrial electric detonators,anti radio frequency and high insensitive electric detonators were manufac-tured by increasing the diameter of the bridge wire,adhering a layer of insensitive film on the surface of the bridge wire,and changing the ignition agent.The ignition current and electrostatic sensitivity tests were conducted on the ignition ele-ments.The results show that the insensitive electric detonator meets the project requirements.The minimum firing current reaches 1.152 A.The electric detonator does not explode at 2 000 pf and 20 kV,far exceeding the electrostatic sensitivity requirements of 2 000 pf and 8 kV.The current safety performance of the detonator is significantly improved.
