EXPLOSIVE OF THE TYPE OF WATER GEL, PROCESS OF ITS PRODUCTION AND ITS USE IN A PAPER CARTRIDGE CASE

摘要

In the present invention, there is disclosed an explosive composition of water gel type that is sensitive to a detonator and is filled in paper cartridge cases, the explosive composition containing 30 to 90 percent by weight of an oxidizer salt, 0.1 to 5 percent by weight of a thickener, 0.01 to 5 percent by weight of a crosslinking agent, 3 to 20 percent by weight of fuel, a sensitizer and water. The sensitizer component of the invented explosive composition contains more than 50 percent by weight of one or more water soluble compounds of oxygen balance more positive than -150 percent and optionally a water insoluble sensitizer in an amount less than 50 percent by weight, in both cases based on total weight of the sensitizer component, whereby the sum of amounts of the water soluble sensitizer and water insoluble sensitizer, if present, is 100 percent by weight of the total sensitizer component weight. Amount of water in the proposed explosive composition is less than 5 percent by weight based on the explosive total weight. Claimed is also a process for preparing the above-described explosive composition, said preparation process comprising preparation of a thickened water phase containing a thickened aqueous solution of a water soluble sensitizer, a thickener and optionally a portion of an oxidizer salt, further a separate preparation of a dry phase including an oxidizer salt or a remainder thereof, a thickener a crosslinking agent, fuel, optionally a water insoluble sensitizer and optionally another water soluble sensitizer, mixing both the phases together and reducing the obtained mixture density. So prepared explosive composition rheology allows it to be filled in paper cartridge cases.
