Problems solved by technology

[0002] Latex explosive is a kind of water-in-oil type industrial explosive made of water phase as dispersed phase and oil phase as continuous phase. Due to temperature changes during production, use and storage and long storage period of raw materials, the interior of latex explosives Partial fission occurs in osmotic pressure, crystallization and demulsification occur, and the detonation velocity and detonation performance indicators of latex explosives are greatly reduced, resulting in expiration and scrapping of latex explosives
Since the waste latex explosives cannot be properly disposed of in time, it will bring great losses to the production and use units. If the latex explosives are destroyed by pit burial and burning, it will not only cause losses to the production enterprises, but also directly pollute the environment.

Embodiment 1

[0009] Put 99.45 kg of scrapped latex explosives into the waste latex explosives processing machine, heat to break the emulsion, the temperature is 80°C, stir for 25 minutes, then add 0.05 kg of modified Span-80 emulsifier, 0.05 kg of industrial paraffin and 0.05 kg of industrial vaseline , 0.05 kg of modified Span-80 emulsifier is a compound composed of 0.02 kg of soybean flour emulsifier and 0.03 kg of Span-80 emulsifier. It is emulsified at 82 rpm to make the original demulsified water phase particles re- The oil phase is coated, and the emulsification time is 20 minutes. After the new stable latex system is completely formed, add 0.4 kg of emulsified rapid foaming agent. The emulsified foaming agent is based on 0.16 kg of nitroso compound, add 0.002 kg of phosphoric acid, 0.002 kg of thiourea, and 0.08 kg of disk- 80 emulsifier and 0.156 kg of diesel oil are emulsified; after mixing for 10 minutes, the temperature is naturally lowered, and the temperature is lowered below ...

Embodiment 2

[0013] Put 95.5 kilograms of latex explosives with a long storage period into the waste latex explosives processing machine, heat and break the emulsion at a temperature of 100 ° C, stir for 20 minutes, then add 1 kilogram of modified Span-80 emulsifier, 1 kilogram of industrial paraffin and 1 1 kg of industrial vaseline, 1 kg of modified Span-80 emulsifier, a compound composed of 0.6 kg of soybean flour emulsifier and 0.4 kg of Span-80 emulsifier, emulsified at 60 rpm to make the original demulsified water phase The particles were re-coated with oil, and the emulsification time was 30 minutes. After the new stable latex system is completely formed, add 1.5 kilograms of emulsified rapid foaming agent. The emulsified foaming agent is based on 0.3135 kilograms of nitroso compounds. 80 emulsifier and 0.885 kg of engine oil are emulsified; after mixing for 5 minutes, the temperature is naturally lowered, and the temperature is lowered below 50 ℃ before it can be sent to charge and...

Abstract

The invention provides a process for recovering waste latex explosive which comprises, (1) charging 95.5-99.5 wt% of emulsion explosive materials, stirring 20-25 minutes at 80-100 deg. C, (2) charging 0.1-3.3% of compound oil phase, emulsifying, the emulsion time being 20-30 minutes, (3) charging 0.4-4.4% of emulsification and foaming agent, mixing 5-10 minutes.

Description

technical field [0001] The invention relates to a recovery method, in particular to a recovery method of waste latex explosives. Background technique [0002] Latex explosive is a kind of water-in-oil type industrial explosive made of water phase as dispersed phase and oil phase as continuous phase. Due to temperature changes during production, use and storage and long storage period of raw materials, the interior of latex explosives Partial fission occurs in the osmotic pressure, crystallization and demulsification occur, and the detonation velocity and detonation performance indicators of the latex explosives are greatly reduced, resulting in the expiration and scrapping of the latex explosives. Since the waste latex explosives cannot be properly disposed of in time, it will bring great losses to the production and user units. If the latex explosives are destroyed by pit burial and burning, it will not only cause losses to the production enterprises, but also directly poll...
