The utility model characteristics are because it is connected with payment to a porter on gland, to make detonator not quick-fried so conductive plug is led away static.The electric conductivity of conduction material depends primarily on the dispersity of inserts, according to seepage theory, originally disperses isolated filler particles after adding dispersant, and its volume disperses to reach a certain critical value, then can form continuous conductive path.At this moment ion is in two states, and the one, the contact of interionic generation physics, its electric charge carrier can flow in continuous conductor; The 2nd, interionic can make carrier itself be activated and move because the bonding thin layer of rubber itself exists.Though material composition plays a decisive role, the basic interaction of the dispersity of filler grain and polymer thereof has also determined the electric conductivity of composite.
The beneficial effects of the utility model are after detonator adopts above-mentioned conductive plug, and detonator is being produced, carries, do not acted on when storing.When static at 2000Pf, be not more than when being added to detonator pin one shell under the 8KV condition, static is led away making detonator not quick-fried by conductive plug, when the power supply that detonates fed detonator with the direct current of regulation or pulse current, detonator was detonated.
