Embodiment 1

[0043] Example 1: Stability detection test of packaged emulsion explosives

[0044] 1. Preparation of latex matrix

[0045](1) Water phase (93.5%): ammonium nitrate 78.5%, sodium nitrate 3%, water 12%

[0046] (2) Oil Phase (6.5%): Oil Phase A / Oil Phase B / Oil Phase C

[0047] (3) The water phase at 100-105°C and the oil phase A / oil phase B / oil phase C at 90-95°C are pumped into the emulsifier at the same time in proportion (water phase: oil phase = 93.5%: 6.5%) After emulsification, latex matrix A, latex matrix B, and latex matrix C were obtained.

[0048] 2. Detection of anti-destructive ability of latex matrix

[0049] Test example 1-1: Take 80g of latex matrix A and put it into a high-speed centrifuge test tube, and centrifuge it at 10000r / min for 40min;

Embodiment 2

[0084] Example 2: Stability detection test of on-site mixed emulsified explosives

[0085] 1. Preparation of latex matrix

[0086] (1) Water phase (93.5%): ammonium nitrate 73.5%, sodium nitrate 5%, water 15%

[0087] (2) Oil phase (6.5%): oil phase D / oil phase E / oil phase F

[0088] (3) The water phase at 80-85°C is pumped into the emulsifier at the same time as the oil phase D / oil phase E / oil phase F at 60-65°C in proportion (water phase: oil phase = 93.5%: 6.5%) Medium emulsification, and then obtain latex matrix D, latex matrix E, latex matrix F.

Abstract

The invention discloses a characterization method of emulsion explosive stability, and belongs to the technical field of emulsion explosive performance detection. According to the characterization method, the damage resistance of an emulsion matrix is characterized by detecting the crystallization rate of the emulsion matrix in the emulsion explosive, so that the stability of the emulsion explosive is characterized. According to the method, the stability of the emulsion explosive can be rapidly and accurately represented, the operation is convenient, the detection time is short, the detection efficiency is high, the stability of the packaged emulsion explosive can be represented, and the stability of the on-site mixed emulsion explosive can also be represented.

Description

technical field [0001] The invention relates to a characterization method for the stability of emulsion explosives, and belongs to the technical field of performance detection of emulsion explosives. Background technique [0002] Emulsion explosive refers to the explosive mixture that forms a W / O latex matrix in emulsification equipment and sensitizes it with a sensitizer by using emulsification technology under the emulsification effect of an emulsifier. It takes the supersaturated solution of oxidant salts such as ammonium nitrate and sodium nitrate as the dispersed phase, and takes oil-soluble or water-insoluble combustible components (such as hydrocarbon fuel) as the continuous phase, and makes the tiny droplets of the dispersed phase through emulsification technology Evenly dispersed in the continuous phase, forming a water-in-oil industrial explosive. Since its invention, it has been widely used due to its excellent explosive properties, good water resistance, flexibl...
