摘要
Abstract
In order to improve the heat resistance of ANFO,urea was mixed with ammonium acetate,potassium sulfate,or acetamide in a 1:1 mass ratio to produce composite additives a,b,and c.Three types of heat-resistant ANFO were prepared by mixing 89.5%porous granular ammonium nitrate,5.7%diesel,and 4.8%composite additives by mass.The effects of three composite additives on the thermal stability and explosive performance of ANFO were studied through TG-DTG experiments,oven heat resistance experiments,and detonation velocity experiments.The results show that the detonation velocity of conventional ANFO is 2 813 m/s,while the detonation velocities of ANFO containing composite additives a,b,and c are 2 791,2 897 m/s,and 1 996 m/s,respectively.The ANFO containing composite additive c has the lowest detonation velocity.The activation energy of conventional ANFO is 164.95 kJ/mol.The activation energy of ANFO containing composite additive a is 193.02 kJ/mol,with the maximum increase in activation energy.Compared with conventional ANFO,the appearance time of the exothermic peak of the three heat-resistant ANFO in a high temperature environment of 240℃is delayed by about 1.39,2.08 hours and 2.78 hours.It can provide reference for the design of the formula of heat-resistant ANFO.关键词
