Embodiment 1
[0021] Embodiment 1: Take the preparation of 500kg powdery emulsion explosive as an example. In the first step, heat and dissolve the mixture of 455kg ammonium nitrate and 15kg water and raise the temperature to 140°C; in the second step, heat and melt 20kg of composite oil phase and 10kg polymer emulsifier such as T152 emulsifier and raise the temperature to 125°C; In the first step, the water phase and oil phase materials are emulsified into latex through an emulsifier, that is, the oxidant water phase and the combustible oil phase are emulsified and mixed to form a uniform latex; the fourth step is to coat the prepared latex on a water-cooled It is solidified on the endless rotating steel belt and cooled by water cooling; in the fifth step, the solidified latex is collected from the endless rotating steel belt, and is made into a powdery emulsion explosive by jet crushing. Of course, sometimes the latex collected from the endless revolving steel belt is already broken, and ...
Embodiment 2
[0022] Embodiment 2: Take the preparation of 500kg powdery emulsion explosive as an example. In the first step, heat and dissolve the mixture of 455kg ammonium nitrate and 15kg water and raise the temperature to 140°C; in the second step, heat and melt 21kg of the composite oil phase and 9kg of polymer emulsifier such as T155 emulsifier and raise the temperature to 120°C; In the first step, the water phase and oil phase materials are emulsified into latex through an emulsifier; in the fourth step, the prepared latex is coated on a water-cooled endless rotating steel belt and solidified, and cooled by water cooling; in the fifth step, the The solidified latex is collected from the endless rotating steel belt, and is mechanically pulverized to make a powdery emulsion explosive. The measured explosion performance is: detonation velocity 4550m / s; detonation distance 11cm; working capacity 356mL.
Embodiment 3
[0023] Embodiment 3: Take the preparation of 500kg powdery emulsion explosive as an example. In the first step, heat and dissolve the mixture of 455kg ammonium nitrate and 15kg water and raise the temperature to 140°C; in the second step, heat and melt 20kg of composite oil phase and 10kg polymer emulsifier such as T152 emulsifier and raise the temperature to 125°C; In the first step, the water phase and oil phase materials are emulsified into latex through an emulsifier; in the fourth step, the prepared latex is coated on a water-cooled rotary drum scraper machine for solidification, and cooled by water cooling; in the fifth step, the The solidified latex is collected from the rotary drum scraper, and is made into a powdery emulsion explosive by means of jet milling. Of course, sometimes the latex collected from the drum scraper is already broken, and there is no need to pulverize it at this time. The measured explosion performance is: detonation velocity 4600m / s; detonation...
