Abstract

En el campo de la voladura, los medios para transmitir una señal de iniciación ( no eléctricamente) a un dispositivo explosivo para detenerlo remotamente de acuerdo con el periodo de retardo predeterminado, comprende partículas mezcladas de un combustible y de peróxido de bario o dióxido de plomo como oxidante, en donde las partículas oxidantes han sido tratadas con un material activo de superficie que se sujeta a las regiones de superficie del peróxido de bario o a las partículas de dióxido de plomo para proporcionar una disposición de superficie de cadenas de hidrocarbilo las cuales actúan como una barrera par impedir el ingreso de vapor de gua y/o de dióxido de carbono, con lo cual una tubería en la cual hay provisto un polvo de esa composición pirotécnica que es capaz de propagar una señal de iniciación desde un extremo de la tubería hasta el otro, se puede utilizar para proporcionar una unidad de retardo en donde la tubería está conectada a un extremo de la misma, cuando menos, a un detonador de retardo o detonador instantáneo de una manera en si conocida.In the field of blasting, the means for transmitting an initiation signal (non-electrically) to an explosive device to remotely stop it in accordance with the predetermined delay period, comprises mixed particles of a fuel and of barium peroxide or lead dioxide as an oxidizer, where the oxidizing particles have been treated with a surface active material that attaches to the barium peroxide surface regions or lead dioxide particles to provide a surface arrangement of hydrocarbyl chains which act as a barrier to prevent the entry of steam vapor and / or carbon dioxide, with which a pipeline in which there is provided a powder of that pyrotechnic composition that is capable of propagating an initiation signal from one end of the pipeline to the other can be used to provide a delay unit where the pipe is connected to one end of the mi sma, at least, to a delay detonator or instantaneous detonator in a manner known per se.
