Abstract

Se presentan mezclas de reaccion exotérmicas que son encendidas eléctricamente con una tira de hoja de bajo costo de dos tiras conductivas separadas por una capa de aislamiento. Uno o más agujeros formados en el encendedor o ocasionador de la ignicion sirven para crear el plasma de chispa en un lado y un plasma de ventilacion en el lado opuesto del agujero. La chispa que tiene bajos requisitos de energía es suficiente para encender e iniciar las reacciones exotérmicas para soldar, colar y otros usos. El encendedor puede ser parte de crisoles y moldes reusables o moldes recipientes y paquetes desechables, o pequeños detonadores para encender cargas mayores. El encendedor puede estar metido o sumergido en o básicamente adyacente a la carga del material exotérmico. El agujero o agujeros formadores de chispa está hecho y conformado por un punzonado en una manera simple y economica. El encendedor elimina la necesidad de polvos de iniciacion o materiales de ignicion y pistolas de pedernal para la ignicion.
