Description

Дл  проверки разработанного способа получени  взрывчатого вещества был изготовлен состав, содержащий на 1000 вес.ч. 389,5 вес.ч. нитрата аммони ,.79 вес.ч. нитрата кальци , 120 вес.ч. нитрата натри , 216 вес.ч нитрата метиламмони , 34 вес.ч. мочевины , 55 вес.ч. алюминиевого по-решка , 11 вес.ч. гуаровой смолы, 87 вес.ч. воды и 8,5 вес.ч. микросфер (на сухой материеил) . Изготовленное в различных услови х (по примерам) указанное выше водонаполненное взрывчатое вещество имело плотность 1,12 г/см, скорость детонации в железных трубах диаметром 32 мм и инициировании от к/д № 8 4400 м/с. В услови х повышенного статического давлени  взрывчатое вещество сохран ет посто ннуюг восприимчивость к инициирующему импульсу и стабильно детонирует. По своим характеристикам разработанное водонаполненное взрывчатое вещество равноценно примерно взрывчатому веществу , содержащему сенсибилизатор, например тротил.To test the developed method for producing an explosive, a composition containing 1000 parts by weight was manufactured. 389.5 weight.h. ammonium nitrate, .79 weight.h. calcium nitrate, 120 weight.h. sodium nitrate, 216 weight.h methyl ammonium nitrate, 34 weight.h. urea, 55 weight.h. aluminum on-tail, 11 weight.h. guar gum, 87 weight.h. water and 8.5 wt.h. microspheres (dry matter). Manufactured under various conditions (by examples), the above-mentioned water-filled explosive had a density of 1.12 g / cm, a detonation velocity in iron pipes with a diameter of 32 mm and initiation from k / d No. 8 4400 m / s. Under conditions of increased static pressure, the explosive remains constant susceptibility to the initiating pulse and stably detonates. According to its characteristics, the developed water-filled explosive is equivalent to about an explosive containing a sensitizer, for example, TNT.
