QJGB型起爆具的研制

Preparation of QJGB Booster

研究了一种特殊装药结构的起爆具,该起爆具以TNT45/RDX55熔铸梯黑炸药为起爆药芯,以纯TNT熔铸炸药为主装药,同传统起爆具相比,高能、敏感组分RDX含量大幅度降低,不仅大幅降低了产品材料成本,也由于RDX的减少而提高了起爆具生产、使用的安全性,产品爆速在7000m/s以上,符合WJ9045—2004Ⅰ型工业起爆具要求,具有良好的经济、社会效益。

Booster with a new charge structure was prepared and studied. TNT45/RDX55 TNT-RDX melt-cast explosive was used as initiating explosive and TNT-based melt-east explosive as main charge. Compared with traditional boosters, a significant reduction of RDX and addition of a high-energy and sensitive component not only reduce the cost of materials but also improve the security in booster manufacturing and using process. The detonation velocity of the product reaches above 7000m/s, which meets the requirements of WJ9045--2004 I industrial booster. The product gains good social and economic benefits.
