摘要：

In order to solve a series of questions on low detonation velocity explosives used in explosion welding which was added into lots of salt, for example hand mixing is heterogeneous, low velocity detonation is unstable, moisture absorption and agglomeration of explosive is easy, ammonium nitrate (AN), wax, diluent, surfactant, gelling agent were mixed into slurry liquid when water temperature was controlled within 105-115 degrees C, and after this liquid was dried, sieved, and cooled at the pressure between -0.07and -0.09Mpa, it can made low detonation velocity explosives used in explosion welding. The microstructure and moisture absorption of the explosive was analyzed, the influence of the charge layout density and thickness on detonation velocity was researched. The results show that each component of the explosives is homogeneous, and is not easy to absorb moisture. When the density is 0.71-0.74g.cm(-3), the detonation velocity is 2300-2380m. s(-1),which can satisfy the requirement of explosion welding of mental plate.
