Laser Initiation of Non-Primary Explosive Detonators

摘要

Aiming to solve the problems caused by primary explosives in traditional detonators, a new kind of non-primary explosive detonator based on the principle of flying plate detonator is invented. However, in some special circumstances, such as high temperature, strong radiation, strong magnetic field, overload, high-pressure conditions, the non-primary explosive detonator cannot work well because of the defects of its usual used initiating method like electric hot wire initiating devices, electric exploding bridge wire initiator, and initiating by a shock-conducting tube, in this context, initiation by low energy laser is applied to non-primary explosive detonator. After this combination, the non-primary explosive detonator performs well in resisting high temperature, high pressure, overload, and electric interference.
