Embodiment Construction

[0055] 1. The present invention is implemented with reference to the following quality percentage composition:

[0056] Ammonium nitrate 97

[0057] Explosion-proof agent 3

[0058] The mass percentage composition of the anti-explosive agent is as follows:

[0059] Zinc sulfate 65

[0060] Zinc oxide 20

[0061] Potassium nitrate 15

[0062] 1.1 Preparation of explosion-proof agent

[0063] Add the above-mentioned components of the anti-explosive agent into the ball mill, pulverize and pass through a 20-mesh sieve, and then add the anti-explosive agent to the mixer according to the above proportion and mix it evenly.

[0064] 1.2 Manufacturing of explosion-proof ammonium nitrate

[0065] Add the anti-explosive agent into the solution tank, and then add the ammonium nitrate washing solution with a temperature of 100°C and a concentration of 15% during the production process of ammonium nitrate in the solution tank at a mass ratio of 1:1, and stir it evenly and fully dissolve it. Ac...

Abstract

The invention discloses an anti-explosion ammonium nitrate for agricultural use, which comprises (by weight portion) ammonium nitrate 90-97, anti-knock agent 3-10, the mass portions of the anti-knock agent include reinforcing agent 40-70, deactivator 20-40, and stabilizing agent 5-20.

Description

Technical field [0001] The present invention is a kind of agricultural explosion-proof ammonium nitrate, which belongs to the modification of ammonium nitrate, is mainly used for agricultural fertilization, and is composed of ammonium nitrate and an explosion-proof agent. Background technique [0002] Ammonium nitrate is the main raw material for the manufacture of civilian explosives, and it is also a kind of agricultural fertilizer. It is very easy to be fried into explosives privately, which seriously endangers public safety. In order to eliminate the illegal act of using ammonium nitrate to fry explosives at the source, ammonium nitrate must be strictly controlled. The sale of ammonium nitrate as fertilizer is prohibited. At the same time, in view of the needs of certain crops for nitrate nitrogen fertilizers, ammonium nitrate is allowed to be modified so that it loses its explosiveness and is irreducible before being sold and used as fertilizer. [0003] In order to solve th...
