Abstract:
     Said explosive is composed of black powder, acrylate and crylonitrile copolymer and graphite. The character of high-energy single-base explosive is high in content of black powder, good in diffusivity and formation of molding powder, high in pressed density and capacity, better in thermal stability and good in compatibility. When the perforation bullet of explosive filler undergoes 180 deg.C for 2h, its armour-piercing performance is unaltered the perforation level is higher than that of the same kind of explosive at home and abroad. The mechanical sensibility of said explosive is lower, and its production and application security is better. It is suitable for all kinds of oil and gas well in perforation under the condition of 180 deg.C and 2h.
