Abstract
In using a plastic explosive composition (PEC), the ignitor, in spite of initially closed stoppers (12), can be inserted very easily and precisely in the PEC. When the PEC is combined with a booster, safe and central placing of the ignitor in the sleeve (11) is ensured, and the PEC, because of the stoppers on both sides, can be safely and densely packed. The PEC contains (wt.%): pentaerythritol tetranitrate and/or hexogen and/or octogen as high explosive material (50-80), dibutyl phthalate and/or diamyl phthalate as plastifying agent (15-30), nitrocellulose (0.5-3), inorganic nitrates, e.g. sodium (Na) and/or potassium (K) nitrate (up to 10), and small amounts of impurities, colorants and inert materials. Independent claims are also included for the following: (1) a process for preparation of the PEC having the above properties involving making a mixture containing (wt.%) dibutyl phthalate and/or diamyl phthalate as plasticizer (15-30) and nitrocellulose (0.5-3) to form a gelatin, to which are added pentaerythritol tetranitrate (nitropenta) and/or hexogen and/or octogen as high explosive materials (50-80), inorganic nitrates (up to 10) and small amounts of colorant and inert materials, until a homogeneous composition is obtained; (2) a booster for the explosive material, especially for the borehole loading tube, a small caliber priming, and a boosting charge for tunnel construction, with a tubular sleeve (11) with plastics stoppers (12) at both end sections, of which at least one can be penetrated by the ignitor for the explosive in the sleeve (11), where the sleeve stoppers (12) are strongly and tightly closed, and at least one stopper has a central opening (19) for an ignitor, so that the ignitor is enclosed centrally, and can be arrested.
