POROUS AMMONIUM NITRATE FOR PRODUCTION OF BLASTING EXPLOSIVES AND A METHOD OF ITS PRODUCTION Russian patent published in 2005 - IPC

FIELD: chemical industry; development of special kinds of raw materials and methods for the raw materials processing to produce the mix type blasting explosives.

SUBSTANCE: the invention is pertaining to the field of making of special kinds of raw and processing methods of its production for making blasting explosives of a mix type. The invention offers a porous granulated ammonium nitrate for making the mix blasting explosives, which contains an additive modifying the space lattice of ammonium nitrate, the pores forming additives and the surface-active substance distributed on the bodies of the granules and also the conditioning seasoning additives on the surface of the granules. As the modifying additive it contains ferrous sulfite (III) and magnesium, calcium, potassium and sodium nitrates at the particular content of ions: Mg⁺², Ca⁺², Na⁺¹, K⁺¹, Fe⁺³, SO₃ ^-2. And also the invention offers a method of production of the porous granulated ammonium nitrate. The technical result of the invention is production of the porous granulated ammonium nitrate with the developed homogeneous porosity space along the body and the surface of the granules, that allows to manufacture the stable explosive mixtures with the balanced contents of an oxidizing agent and a liquid oil product.

EFFECT: the invention ensures production of the porous granulated ammonium nitrate with the developed homogeneous porosity along the body and the surface of the granules, manufacture the stable explosive mixtures with the balanced contents of an oxidizing agent and a liquid oil product.
