METHOD TO MANUFACTURE A WATER-RESISTANT NON-PREVENTIVE EXPLOSIVE Russian patent published in 2004 - IPC

FIELD: chemical industry. SUBSTANCE: the invention presents a method to manufacture a water-resistant nonpreventive explosives made of the utilized ballistite and pyroxyline blasting powders. The offered method of manufacture of the water-resistant nonpreventive blasting explosive, provides for ammunition of the powder elements, forge-rolling, a batching and packing. In the process of the forge-rolling the comminuted powder elements are added with a sensitizer that has a form of suspensions or a powder. In the capacity of the sensitize they use oxides of metals, and before the batching the pressing is performed. The invention promotes production of a water-resistant non-preventive blasting explosive with good sensitivity to the initiation means and rather high detonation features. EFFECT: the invention allows to produce waterproof-explosive with good sensitivity initiating means. 1 dwg, 1 tbl
