Description

I

The invention relates to BoaoHantuiHeH explosives, designed for charging {% 1vnogo work with mechanized charging of charges and shurfda at 5 ° C. The closest explosive to the invention is the waterfilled explosive composition containing O-8O wt.% Inorganic oxidant nitrate salts or ammonium, sodium or calcium perchlorate, mainly 5O-70%, of which 2O-65% ammgavi nitrate with 5-5O% sodium nitrate, O, 5-25% water, up to 5%. liquid total water soluble

this LENGLIKOL, PRMSHSLENGOL, methyl or ethyl alcohol, 0.05-10% aluminum powder or powder, 4% sulfur, 2-1O% vegetable fiber or 15-6O% vegetable fiber, covered outside with asphaltite, 0.1-20% TNT hexagon on or smokeless powder, thickener, not forming cross-links in the form of 0.05-1.5% of guar gum and 0.5-4.0% of starch and up to 0.2 salts of pshk boric acid, forming upon thickening zi jl. The water-filled explosive is resistant to water even when the package is torn in a chip where water is contained. After production | back (veschesovogo case is FORCE but thickened, which does not allow it to be used for mechanized loading of the fox-holes, especially small diametpia. It has insufficient fluidity when spilling from capping and ksteinerov.

The aim of the invention is the creation of a physically stable explosive composition up to 60 ° C, which can be freely poured up to 5 ° C from (containers and closures) and used for pumping by pumps when charging by a hole with a diameter of 76.2-12.7 mm.

For this purpose, an antimony or chromic acid salt is introduced into the proposed explosive composition as a cross-linking agent using the following ratio of components, wt.%: Liquid or solid dispersed fuel 11.5-40.0 or a mixture of 1O, O-4O, 0 V ode Thickener - guar gum or O, 2-5, O starch or their mixture Salt of antimony or 0, b5-O, 25 chromic acid Eutectic mixture, ammsis nitrate with the rest, sodium nitrate Explosive is obtained by diluting salts of oxidant in water, heating the solution to 25–30 ° С, adding liquid fuel and guar gum and thickening the mixture at this temperature. After that, the thickened solution is mixed until homogeneous with the remaining components, including salt and starch. Known manufacturing equipment is used to manufacture and transfer the mixture. To check the composition and its characteristics, the following were made. samples containing, wt.%:
