Abstract


This paper researched the small size booster explosive of groove channel through simulation kneading technology of mixed explosives and crowded note charging process.The formula of booster explosive was determined based on HMX/HTPB which can detonate steadily with mould groove width under the condition of 2mm: HMX 90% - 92%, HTPB 3% - 5%, DOS 1.0% - 2.0%, and EBUTYL ACETATE is 3 times the quantity of HTPB. With mould size 0.8 mm, 1.0 mm and 2.0 mm, booster explosive charging density was 1.54±0.08g/cm3, detonation velocity was 7120±100m/s (2.0 mm mold inside) .The formula of booster explosive was also determined based on PETN/SILASTIC which can detonate steadily with mould groove width under the condition of 0.8mm、1.0mm、2mm: PETN: 78% - 88%, SILASTIC 5% - 15%, DOS 1.0% - 2.0%, and TOLUENE is 5 times the quantity of SILASTIC. At above situation,the booster explosive charging density was 1.15±0.08g/cm~3, and the detonation velocity was 4908±100m/s.The formula of booster explosive was determined based on CL-20/SILASTIC which can detonate steadily with mould groove width under the condition of 0.8mm, 1.0mm and 2mm: CL-20 80% - 90%, SILASTIC 3% - 12%, DOS 1.0% - 2.0%, and PETROLEUM ETHER is 2-2.5 times the quantity of SILASTIC. At above situation,the booster explosive charging density was 1.14±0.08g/cm~3, and the detonation velocity was 5443±100m/s.This paper established injection processing equipment and methods for the small size booster explosive charging of groove channel, and studied the booster explosive formula though three main explosives for optimization of process parameters.The charging density and detonation wave propagation speed under different charging size were obtained. This study established experimental basis for researching the small size booster explosive charging of groove channel in depth, and provided a better way to study booster explosive.
