Problems solved by technology

People often increase the detonation and storage period of explosives by increasing the proportion of oil phase, but this brings unsafe factors to the production of emulsion explosives. The emulsion matrix generally has detonator sensitivity. In the production of high temperature, high speed and high pressure, It is easy to cause an explosion and cause casualties
In order to ensure the safety of the emulsified matrix, people use low temperature, low speed, and increased water content for production, resulting in problems such as insufficient strength of the emulsified matrix, short storage period, and reduced working ability.

Embodiment 1

[0010] Add 13.5 kg of tap water into the water phase dissolving tank with a power of 3kw and a rotation speed of 1480 rpm, then add 75 kg of ammonium nitrate, 3.5 kg of sodium nitrate, and 2 kg of urea to heat and dissolve, and wait until the temperature rises to 100°C to keep warm for later use. 60 minutes; mix 3 kg of modified Span-80 with 3 kg of compound oil, add it to the oil phase dissolution tank to raise the temperature, when the temperature is 98 ° C, keep it warm for 60 minutes, and it is the oil phase; 3 kg of modified Span -80 is a mixture of 1.2 kg of soybean flour emulsifier and 1.8 kg of Pan-80. 3 kg of composite oil phase is a mixture of 1 kg of disc-801 kg of industrial paraffin and 1 kg of industrial vaseline. After the above-mentioned water phase and oil phase materials are filtered, the water phase conveying equipment and oil phase conveying system are sent to the emulsifier for automatic emulsification. The power of the emulsifier is 18.5kw and the speed i...

Embodiment 2

[0012] Add 13.8 kg of tap water to the water-phase dissolving tank, the power of the water-phase dissolving tank is 3kw, and the speed is 1480 rpm, then add 85 kg of ammonium nitrate, 0.3 kg of potassium nitrate or magnesium nitrate, and 0.3 kg of urea to heat and dissolve until the temperature rises to 110 ℃ heat preservation for standby, the heat preservation time is 80 minutes; mix 0.3 kg of modified Span-80 with 0.3 kg of compound oil, add it to the oil phase dissolution tank to raise the temperature, when the temperature is 80 ℃, heat preservation for 80 minutes, it is the oil phase ; 0.3 kg of modified Span-80 is a mixture of 0.18 kg of soybean flour emulsifier and 0.12 kg of Span-80. The 0.3 kg composite oil phase is a mixture of 0.1 kg disc-80, 0.1 kg industrial paraffin and 0.1 kg industrial vaseline. After the above-mentioned water phase and oil phase materials are filtered, the water phase conveying equipment and oil phase conveying system are sent to the emulsifier...

Abstract

The invention relates to an emulsified base without exploder sensitivity and method for preparation, wherein the method comprises, (1) charging 8-15wt% of water into 75-85wt% of ammonium nitrate, agitating, charging 0.3-3.5% of nitrate and 0.3-2% of urea, agitating, when the temperature rises to 100-110 deg. C, thermal insulating 60-80 minutes, thus obtaining aqueous phase, (2) mixing 0.3-3% of modified Span-80 and 0.3-3% of compound oil phase, elevating the temperature to 80-98 deg. C, thermal insulating 60-80 minutes, thus obtaining oil phase, (3) filtering the aqueous phase and the oil phase, mixing and emulsifying, thus obtaining emulsified base material.

Description

technical field [0001] The invention relates to an emulsified base without detonator sensitivity and a preparation method thereof. Background technique [0002] In the production of emulsion explosives, the safety of emulsion matrix directly affects the production safety of emulsion explosives. People often increase the detonation and storage period of explosives by increasing the proportion of oil phase, but this brings unsafe factors to the production of emulsion explosives. The emulsion matrix generally has detonator sensitivity. In the production of high temperature, high speed and high pressure, It is easy to cause an explosion and cause casualties. In order to ensure the safety of the emulsified matrix, people adopt the method of low temperature, low speed and increased water content for production, resulting in problems such as insufficient strength of the emulsified matrix, short storage period, and reduced working ability. Contents of the invention [0003] The ...
