A Study of Effect of Confinement, Obtuaration and Venting on Burning Rate of Modified Pyrotechnics Delay Composition in Delay Detonator
A study was carried out to determine effect of confinement, obturation and venting on burning rate of modified pyrotechnics delay composition (Silicon 14%, PbO 11% and Pb2O3 75%) in electrically initiated delay detonator. A cylindrical aluminum body of specification AA-2024 having inner bore to contain delay composition was used as a delay body and Nichrome wire 80/20 was used as hot bridge wire. This delay detonator consists of electrical primer, detonator body, delay composition and bursting charge. In this study effect of Confinement, Obturation and Venting of delay body on burning rate of modified delay composition was determined and compared. All other parameters such as consolidation pressure and quantity of delay composition were kept constant.
