摘要:
将硝酸铵、硝酸钠、尿素、水、机油和Span80等通过乳化技术制备出乳胶基质。将制备好的乳胶基质和泡沫树脂混合，得到一种平板状炸药。实验表明：该种炸药的密度可低至0.17g/cm3，爆轰的临界厚度为18 mm，在最低临界密度下的爆速为1 678 m/s；随着密度的增加，爆速增加。密度为0.23 g/cm3时，测得爆速为2 149 m/s。初步分析，该炸药可满足某些爆炸焊接工艺的要求。
Abstract:
An explosive matrix containing ammonium nitrate, sodium nitrate, urea, water, engine oil and emulsifier was prepared by emulsifying technology. The explosive matrix was fully mixed with flexible foam and a flexible flat explosive was manufactured. Experimental results show that density of this explosive can be as low as 0.17 g/cm3, and the critical detonation thickness is 18 mm. Detonation velocity at the lowest critical density is 1 678 m/s. With the increases of density, the detonation velocity increases. Detonation velocity of the flexible flat explosive is 2149 m/s with a density of 0.23 g/cm3, which could meet the requirements of some explosion welding.
