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.

Abstract: A spark generating tube includes a single tube and a pyrotechnical mixture. The single tube only has a single layer of plastic material, such as ethylene vinyl acetate (EVA) and polyethylene. The pyrotechnical mixture has formed a thin layer in contact with the single layer of the single tube. The pyrotechnical contains an oxidizer, a reducing agent, a substance with low temperature of Tammann and an agent for lubricating and adhering, wherein the agent for lubricating and adhering is either talc or graphite, and the reducing agent can be an aluminum powder in microscale. During the process for manufacturing a spark generating tube, the mixture of the oxidizers and additives is formed separately from the reducing agent. The final mixture is obtained only in the single tube formed with an extruder. In this way, only a very small amount of pyrotechnic mixture is formed at any instant.
