Abstract

SE REFIERE A UN ELEMENTO RETARDANTE PARA UTILIZARSE EN UN DETONADOR QUIMICO, EL QUE INCLUYE DENTRO DE UNA CARCASA TUBULAR CON SUS EXTREMOS ABIERTOS UN CONJUNTO QUE COMPRENDE: UNA CARGA SELLADORA FABRICADA EN MATERIAL PIROTECNICO EN CONTACTO SELLADOR CON LA SUPERFICIE INTERNA DE LA CARCASA TUBULAR; UNA CARGA TEMPORIZADORA FABRICADA A PARTIR DE UN COMPUESTO TEMPORIZADOR Y EN CONTACTO CON LA CARGA SELLADORA; UNA CARGA INICIADORA EN CONTACTO CON LA CARGA TEMPORIZADORA Y SEPARADA POR MEDIO DE ELLA DE LA CARGA SELLADORA, Y UNA CARGA BASE EN CONTACTO CON LA CARGA PRIMARIA Y SEPARADA POR MEDIO DE ELLA DE LA CARGA TEMPORIZADORA. ADEMAS SE DESCRIBE UN DETONADOR QUIMICO QUE INCLUYE UN ALOJAMIENTO QUE CONTIENE EN SU INTERIOR UN ELEMENTO RETARDANTE, ASIMISMO SE DESCRIBE UN METODO DE FABRICACION DE UN ELEMENTO RETARDANTE PARA SU UTILIZACION EN UN DETONADOR QUIMICOIT REFERS TO A RETARDING ELEMENT TO BE USED IN A CHEMICAL DETONATOR, WHICH INCLUDES WITHIN A TUBULAR CASE WITH ITS OPEN ENDS A SET INCLUDING: A SEALING CHARGE MADE OF PIROTECHNICAL MATERIAL WITH THE INTERIOR SEALING TUBE WITH THE SUPERIOR SEALING TUBE IN THE INTERIOR SEALING TUBE. A TIMING CHARGE MANUFACTURED FROM A TIMING COMPOUND AND IN CONTACT WITH THE SEALING CHARGE; AN INITIATING CHARGE IN CONTACT WITH THE TIMING CHARGE AND SEPARATED THROUGH IT FROM THE SEALING CHARGE, AND A BASE CHARGE IN CONTACT WITH THE PRIMARY CHARGE AND SEPARATED THROUGH IT FROM THE TIMING CHARGE. IN ADDITION, A CHEMICAL DETONATOR IS DESCRIBED THAT INCLUDES A HOUSING THAT CONTAINS INSIDE A RETARDANT ELEMENT, ALSO DESCRIBES A METHOD OF MANUFACTURING A RETARDANT ELEMENT FOR USE IN A CHEMICAL DETONATOR
