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 kilograms of scrap latex explosives into the waste latex explosives processor, heat to demulsify, temperature 80 ℃, stir for 25 minutes, then add 0.05 kg modified Span-80 emulsifier, 0.05 kg industrial paraffin and 0.05 kg industrial petrolatum , 0.05 kg of modified Span-80 emulsifier is a compound composed of 0.02 kg of soy flour emulsifier and 0.03 kg of Span-80 emulsifier, emulsified at 82 rpm, so that the original demulsified water phase particles will be renewed Oil phase coating, emulsification time 20 minutes. After the new and stable latex system is completely formed, add 0.4 kg of emulsified fast foaming agent, which is based on 0.16 kg of nitroso compound, and add 0.002 kg of phosphoric acid, 0.002 kg of thiourea, and 0.08 kg of Span- 80 emulsifier, 0.156 kilograms of diesel emulsified; after mixing for 10 minutes, the temperature is cooled naturally, and the temperature is below 50 ℃, then it can be sent to the charge and packaged into latex explosives ...

Embodiment 2

[0013] Put 95.5 kg of latex explosives with too long storage period into the waste latex explosives processor, heat to demulsify, stir for 20 minutes at a temperature of 100 ℃, and then add 1 kg of modified Span-80 emulsifier, 1 kg of industrial paraffin and 1 Kg of industrial petroleum jelly, 1 kg of modified Span-80 emulsifier A compound composed of 0.6 kg of soybean powder emulsifier and 0.4 kg of Span-80 emulsifier, emulsify at 60 rpm to make the original water phase demulsified The particles are re-coated with the oil phase, and the emulsification time is 30 minutes. After the new and stable latex system is completely formed, add 1.5 kg of emulsified fast foaming agent, which is based on 0.3135 kg of nitroso compound, and add 0.00075 kg of phosphoric acid, 0.00075 kg of thiourea, and 0.3 kg of Span- 80 emulsifier, 0.885 kg of engine oil emulsified; after mixing for 5 minutes, the temperature is cooled naturally, and the temperature is below 50 ℃, before being sent to the char...

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 recycling method, in particular to a recycling method of waste latex explosives. Background technique [0002] Latex explosive is a kind of water-in-oil industrial explosive made with water phase as the dispersed phase and oil phase as the continuous phase. Due to temperature changes during production, use and storage, and the long storage period of raw materials, the inside of the latex explosive The osmotic pressure undergoes local fission, crystallization, demulsification, and explosive performance indicators such as detonation speed and blasting of latex explosives are greatly reduced, resulting in latex explosives expired and scrapped. Since waste latex explosives cannot be properly disposed of in a timely manner, it will bring greater losses to production and use units. If pit burial and burning methods are used to destroy latex explosives, it will not only cause losses to manufacturers, but also directly pollute the environ...
