Abstract:
A new type high st reng th ammonium nitrate pow dery explosive containing aluminium is manufactured by mixing oxidizer, a kind of ex panded ammonium nitrate, which possesses many microholes and sel-f sensitivity, with reducing agent , w hich is the mixture of wood pow der, composite fuel oil and aluminium powder. By mathematical model for prescript ion design and opt imizat ion of the indust rial explosive w hich contains chemical elements such as C, H, O, N, Al and ex perimental research, a good prescription of pow dery ammonium nitrate explosive containing aluminium pow der is obtained, the formulation is expanded ammonium nit rate 85. 5 % ~ 89. 5 % , w ood powder 3. 5 % ~ 4. 5 % , composite fuel oil 2. 0 % ~ 3. 0 %, alumin-i um pow der 5. 0 % ~ 7. 0 % . The explosion property parameters of this kind of commercial explosive are detonation velocity ( 32 mm) 3 600~ 3 800 m/ s, brisance 16. 00~ 17. 00 mm, sensit ivity to initial detonat ion 12~ 14 cm, st rength 370~ 390 mL, charge density 0. 92~ 0. 95 g / cm3. The relat ion betw een the amount of aluminium pow er in ex plosive and explosion property is also discussed in this paper, w hen the amount of aluminium pow er in ammonium nit rate explosive is 6. 5 %~ 7. 0 %, the strength arrives maximum.
