| 摘要 |
The technical field of the invention is that of the manufacture of explosive compositions comprising a water-in-oil emulsion containing of a mixture of two phases immiscible in one another, a continuous phase (2) comprising organic combustible components, and a discontinuous phase (1) in a dispersed oxidizing solution. The emulsion is stabilized by the presence of at least one surface-active agent mixed at least in one of said phases, wherein it is soluble, and of a surface-active agent reinforcing additive. According to the invention, the additive selected is insoluble in each of the two phases, and is used to form a third phase (3) in said emulsion, the third phase (3) being situated between the droplets (4) of the discontinuous phase (1). The third phase acts as a barrier between the droplets and increases emulsion stabilization.
