DETONATING CORD Russian patent published in 1995 - IPC

FIELD: blasting work. SUBSTANCE: detonating cord comprises leading threads 1 made from lavsan yarn, core 2 from an explosive material, windings 3-5 from lavsan yarn, shell 6 from modified polyvinylchloride plastic compound of high elasticity with a relative elongation of 250-460% plasticized with dioctylsebacinate. Shell thickness is determined by a relation h (0.05-1.0)d, where h shell thickness; d diameter of detonating cord. After initiating from one end of the cord, a detonating wave spreads along the cord length and transmits the detonation process to explosive substances. EFFECT: higher operating characteristics achieved by improving mechanical properties under low temperatures, high pressures and in aggressive media. 1 dwg
