Abstract
“THERMAL SPARK CONDUCTOR TUBE USING NANOMETRIC PARTICLES”, refers to the Invention Patent for a thermal spark conductor tube, applied as a signal transmitter for connection and initiation of explosive columns, which employs a low toxicity nanometric pyrotechnic mixture, with superior thermal performance of the spark which maintains the advantages of the current pyrotechnic shock tube and has additional advantages of reducing or even eliminating the use of contaminants from underground water, presenting a lower risk of conducting an electrostatic discharge of the human body to its end, and to use pyrotechnic mixture production process quite simple and with less risk of accidents due to friction and mechanical shocks.
