摘要:
为了探究用硼系延期药制作高秒量雷管的可行性，采用了不同管体材料和不同壁厚的同种材料制作低燃速硼系延期体。研究结果表明：由于预热效应的存在，延期药的燃烧速度随着管体材料导热系数的增加而变快，从热绝缘材料到导热材料，延期药的燃烧速度跳跃式增加；当延期体管体为同种导热材料时，在热散失和热传导的双重作用下，延期药燃速随着管体壁厚的增加而降低，但是相对精度却不是随壁厚的增加发生一致性变化，延期体精度随着壁厚的增加先升高然后降低，在壁厚为4 mm时的延期精度最高。
Abstract:
Several pipe materials having various wall thickness were used in the fabrication of boron type delay charges with low burning rate to explore the feasibility of producing high second delay detonator. Experiment results show that, due to the existence of pre-heating, the burning rate of the delay compositions increased with the increased thermal conductivity of the package, especially an abrupt increase when materials nature was changed from heat insulator to heat conductor. For the same type of heat conducting pipe material, the burning rate of the delay compositions will decrease with increased wall thickness due to the effect of heat dissipation and heat conduction. The accuracy of delay composition was observed as increasing with the increased wall thickness to the apex, which corresponds to a wall thickness of 4 mm, and then followed by decreasing.
