民爆库

摘要：  
对比了乳化炸药敏化技术的现状,提出了树脂微球可作为乳化炸药的物理敏化剂,并通过试验数据分析了采用树脂微球敏化的乳化炸药密度、爆炸性能、黏度、泵送稳定性、储存稳定性,来评价树脂微球作为乳化炸药敏化剂的敏化效果.结果表明:树脂微球的质量占乳胶基质质量的0.35%~0.45%时,制备的乳化炸药密度为1.09~1.15 g/cm3,爆速为5200~5400 m/s,殉爆距离为6~9 cm;高温80℃左右时,树脂微球敏化的乳化炸药黏度略高于化学敏化的乳化炸药,远小于膨胀珍珠岩敏化的乳化炸药;树脂微球敏化的乳化炸药泵送稳定性优于化学敏化及膨胀珍珠岩敏化的乳化炸药.
Abstract：  
Status of sensitizing technology of emulsion explosives was compared. Resin microspheres were proposed to be used as a good physical sensitizer in preparation of emulsion explosive. Sensitizing performance of emulsion explosive sensitized by resin micro spheres was evaluated in terms of density, blasting performance, viscosity, pumping stability and storage stability in test. The results show that when the mass fraction of the resin microsphere is 0. 35%-0. 45%, the density of the emulsion explosive prepared is 1. 09-1. 15 g/cm3 , the detonation velocity is 5200-5400m/s and the gap distance is 6-9 cm;at high temperature of 80℃, the viscosity of emulsion explosive sensitized by resin microsphere is slightly higher than that of the emulsion explosive sensitized chemically, and it is far less than that of emulsion explosive sensitized by expanded perlite;the pumping stability of the emulsion explosive sensitized by resin microsphere is superior to the emulsion explosive sensitized by chemical method and expanded perlite.
