Abstract

La invencion proporciona un dispositivo para la iniciacion de una detonacion por un detonador, el dispositivo incluye dos conductores eléctricos espaciados; una substancia resistente que se extiende entre los conductores eléctricos, para liberar energía en la aplicacion de una corriente eléctrica a la sustanciaresistente; y una composicion explosiva que incluye diazodinitrofenol (DDNP), que cubre la substancia resistente. La composicion explosiva incluye DDNP enforma de partículas finas tanto como en la forma de partículas relativamente mayores. El dispositivo para la iniciacion de una detonacion, de acuerdo con lainvencion, no solamente es muy estable y resistente a la explosion accidental, sino que también es confiable debido a la presencia del DDNP de partículas finas. Además, la composicion explosiva del dispositivo para la iniciacion de una detonacion puede ser iniciado aun a los niveles de energía en los cuales losdispositivos de iniciacion electronicos usualmente operan.The invention provides a device for initiating a detonation by a detonator, the device includes two spaced electrical conductors; a resistant substance that extends between the electrical conductors, to release energy in the application of an electric current to the resistant substance; and an explosive composition that includes diazodinitrophenol (DDNP), which covers the resistant substance. The explosive composition includes DDNP in the form of fine particles as well as in the form of relatively larger particles. The device for the initiation of a detonation, according to the invention, is not only very stable and resistant to accidental explosion, but it is also reliable due to the presence of fine particle DDNP. In addition, the explosive composition of the device for the initiation of a detonation can be initiated even at the energy levels at which the electronic initiation devices usually operate.
