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 oil, and adding 333 to 2000 grams of Sudan Red per 1000L of diesel oil; its preparation method is as follows: first , adding 333-2000 grams of Sudan Red to every 1000L of diesel oil; then, mixing the diesel oil containing Sudan Red and ammonium nitrate on site, and the ammonium oil explosive after mixing is pink; after that, the explosive obtained in the above steps The ratio between ammonium nitrate and diesel in the ammonium fuel explosive can be determined visually by comparing with the reference color on the color guide.

[0022] In specific applications, pre-made swatches. By visually inspecting the color of the ammonium fuel explosive after mixing and comparing it with the contrast color on the color guide, the ratio relationship between ammonium nitrate and diesel oil which is closer to zero oxygen balance in the ammonium fuel explos...

Embodiment 2

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

[0032] (The proportion of ammonium oil explosive zero oxygen balance: ammonium nitrate 94.5%, diesel oil 5.5%)

[0033] When 1000g of Sudan Red is added to every 1000L of diesel oil, 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 are added to every 1000 L of diesel oil.

[0036] diesel content

Ammonium dynamite presents color

[0038] (The proportion of ammonium oil explosive zero oxygen balance: ammonium nitrate 94.5%, diesel oil 5.5%)

[0039] When adding more than 2000 grams of Sudan Red per 1000L of diesel, the visual colorimetric effect is relatively inconspicuous, and Sudan Red cannot be completely dissolved in 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 oil explosives, an ammonium oil explosive containing Sudan red and a preparation method of the explosive. Background technique [0002] Industrial explosives are multi-component mixtures, which are generally divided into oxidizers, combustibles, sensitizers and functional additives. The oxidant and combustible agent of ammonium oil explosives are porous granular ammonium nitrate and diesel oil respectively. After the explosion, it mainly generates 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 that the amount of toxic gas generated after explosive explosion should be the least. In order to meet this requirement, the formula of industrial explosives is designed to be in zero oxygen balance, and the explosive’s working ability i...
