Problems solved by technology

The high-temperature sensitization process is currently immature, and most of them use chemical sensitization, but the temperature is high, the bubbles are formed quickly, there are many large bubbles, and there are few effective bubbles, which affects the explosion effect of explosives, and the storage is unstable and the storage cost is high.

Abstract

The invention discloses a preparation process of emulsion explosive, which belongs to the field of explosive preparation. In the technical process for preparing the emulsion explosive, a mixture of Matsumoto microspheres F and water is used as a sensibilizer. The preparation process of the emulsion explosive of the invention has the characteristics of simple technical process, high processing efficiency and low production. The emulsion explosive prepared by the process has the characteristics of ideal explosion effect and low storage cost.

Description

technical field [0001] The invention relates to the field of explosive preparation, in particular to a preparation process of emulsion explosive. Background technique [0002] Emulsion explosive is the main variety of industrial explosives at present, and it is the development direction advocated by the industry. The main composition of the explosive is ammonium nitrate, sodium nitrate, and water as the dispersed phase, the oil phase (liquid oil and solid wax) as the continuous phase, and an emulsifier to form a water-in-oil structure. The emulsified matrix formed in this way does not have a high density of detonator sensitivity, and the density can be adjusted by adding a certain amount of sensitizer to increase the sensitivity. [0003] The detonation principle of emulsion explosives is called the scorching nuclear principle, also known as the hot spot theory. After the sensitizer is added, many dispersed small bubbles will be formed in the emulsion explosive. After the ...
