Problems solved by technology

Most of the formulas use 94.5% porous granular ammonium nitrate and 5.5% diesel oil. Due to the current formula, it is difficult for the operator of the ammonium oil explosive vehicle to ensure that the explosives loaded in each blasthole meet the requirements of the formula, resulting in the explosion and working ability of the explosives. Small, poor blasting effect

Embodiment 1

[0021] An ammonium oil explosive containing Sudan Red, comprising 94.5±0.5% by weight of ammonium nitrate and 5.5±0.5% by weight of diesel, and adding 333-2000 grams of Sudan Red to every 1000L of diesel; the preparation method is as follows: , Add 333-2000 grams of Sudan Red per 1000L of diesel; then, mix the diesel containing Sudan red with ammonium nitrate on site, and the mixed ammonium explosive is pink and mixed; then, the explosives obtained in the above steps are mixed By comparing with the control color on the colorimetric plate, the ratio between ammonium nitrate and diesel in the ammonium explosive can be determined by naked eyes.

[0022] In specific applications, make a color comparison board in advance. By visually inspecting the color of the mixed ammonium oil explosive and comparing it with the control color on the colorimetric plate, the ratio of ammonium nitrate and diesel oil in the ammonium oil explosive which is closer to zero oxygen balance is obtained.

Embodiment 2

[0030] The difference between this embodiment and the foregoing embodiment is that 1000 grams of Sudan Red is added to every 1000 L of diesel.

[0031] Diesel content

Ammonium explosives show color

Remarks

0~3%

White, a small amount of pink ammonium nitrate particles

3%~5%

Light pink with a few white ammonium nitrate particles

5%~6%

Pink and uniform color, no white ammonium nitrate particles

Target color

More than 6%

Crimson

[0032] (Proportion of ammonium oil explosives with zero oxygen balance: 94.5% ammonium nitrate, 5.5% diesel)

[0033] When 1000 grams of Sudan Red is added to each 1000L of diesel, the visual colorimetric effect is relatively obvious.

Embodiment 3

[0035] The difference between this embodiment and the foregoing embodiment is that 2000 grams of Sudan Red is added to every 1000 L of diesel.

[0036] Diesel content

Ammonium explosives show color

Remarks

0~3%

White, a small amount of pink ammonium nitrate particles

3%~5%

Light pink with a few white ammonium nitrate particles

5%~6%

Pink and uniform color, no white ammonium nitrate particles

Target color

More than 6%

Crimson

[0037] (Proportion of ammonium oil explosives with zero oxygen balance: 94.5% ammonium nitrate, 5.5% diesel)

[0038] When more than 2000 grams of Sudan Red is added to each 1000L of diesel, the visual colorimetric effect is relatively insignificant, and Sudan Red cannot be completely dissolved in the diesel, forming a precipitate.

Abstract

The invention relates to an application of Sudan red for preparing an ammonium nitrate fuel oil explosive (ANFO), and an ANFO containing the Sudan red and a preparation method thereof. The invention can enable a field operator to visually ensure that the ANFO meeting the formula requirement into each blast hole through a color board, reduces the emission of toxic gas, improves the capacity for work of the explosive, obtains good blasting effect, and meets the requirement of green organization on least content of toxic gas generated after the explosive explodes.

Description

Technical field [0001] The invention relates to the application of Sudan Red in ammonium explosives, an ammonium explosive containing Sudan Red and a preparation method of the explosives. Background technique [0002] Industrial explosives are multi-component mixtures. These components are generally divided into oxidizers, combustibles, sensitizers and functional additives. The oxidant and combustible agent of ammonium explosives are porous granular ammonium nitrate and diesel respectively. After the explosion, they mainly produce water vapor, nitrogen, nitrogen monoxide, nitrogen dioxide, carbon monoxide, carbon dioxide and other gases, among which nitrogen oxide and carbon monoxide are poisonous gases. [0003] Green chemistry requires explosives to produce the least amount of toxic gas after explosion. In order to meet this requirement, the industrial explosives formula is designed to have zero oxygen balance, at this time the explosives have the greatest working power; under ne...
