Embodiment 1

[0012] First, the powdered ammonium nitrate to be modified is pretreated to make it into 1.5mm particles, and its moisture content is controlled to 2.5%, and the temperature is 90°C to 120°C; the above-mentioned materials that have been pretreated are melted The molten urea is wrapped with urea, the pressure of the molten urea is 1Mpa, the temperature is 135°C-145°C, it is sprayed on the ammonium nitrate particles, and the non-explosive ammonium nitrate is produced by the rotary drum fluidized bed spray granulator. Particles, so that ammonium nitrate becomes a safe inert substance that is non-flammable and non-explosive, and achieves the purpose of modification.

Embodiment 2

[0014] First, the powdered ammonium nitrate to be modified is pretreated to make it into 2mm particles, and its moisture content is controlled to 3%, and the temperature is 90°C to 120°C; the above-mentioned materials that have been pretreated are melted The urea is wrapped, the pressure of the molten urea is 1.2Mpa, the temperature is 135 ° C ~ 145 ° C, sprayed on the ammonium nitrate particles, and granulated by a fluidized bed granulator, the non-explosive ammonium nitrate particles are formed, thereby Make ammonium nitrate into a non-flammable and non-explosive safe inert substance to achieve the purpose of modification.

Abstract

The invention relates to a method for solving explosion property of ammonium nitrate explosives, which is characterized by that firstly, the powdered ammonium nitrate explosive substance to be modified is pretreated and made into 0.5-5 mm granules, and the granular explosive substance has no need of pretreatment, then the molten non-explosive and incombustible substances of urea, etc, can be sprayed on the pretreated above-mentioned explosive substance to form a layer of inert protecting layer so as to make said whole material become into non-explosive and incombustible safe inert substance and can attain the goal of modifying ammonium nitrate explosives. Said invention is safe, reliable and high in product quality.

Description

technical field [0001] The invention relates to a method for solving the explosive performance of explosives, in particular to a method for solving the explosive performance of ammonium nitrate. Background technique [0002] Chemical products such as nitrates, chlorates, and ammonium salts are unstable and prone to explosion. [0003] After retrieval, it is known that the methods for solving the explosive performance of explosives are to add loosening agent to explosives, or to change its structure. Such as: [0004] Patent Publication No. 1144792 discloses a powdery ammonium nitrate explosive and its process method in the field of civil blasting explosives. Increase and promote the physical characteristics of ammonium nitrate volume expansion, and through the action of stabilizers, ammonium nitrate powder quickly and safely disperses composite fuel oil. At a certain temperature, the oil film shrinks and fixes evenly, forming a stable, bulky fine powder Ammonium nitrate e...
