Safe extraction method of ammonium perchlorate in solid cloud detonation agent

Abstract

The invention relates to the technical field of security treatment of solid energetic materials, and particularly discloses a safe extraction method of ammonium perchlorate in a solid cloud detonation agent. The method comprises the steps of mixing a powdery cloud detonation agent containing ammonium perchlorate, a certain amount of water and a surfactant evenly, wherein the dosage of the surfactant is 1-4% of weight of the solid cloud detonation agent; and carrying out ultrasonic extraction on a mixed feed liquid by using an ultrasonic extraction device at room temperature, and extracting the ammonium perchlorate into a water solution, wherein the surfactant is a sodium sulfonate anionic surfactant. According to the method, the ammonium perchlorate in the solid cloud detonation agent can be recovered at room temperature, so that the extraction time is obviously shortened, the extraction efficiency is significantly improved and the safe extraction method has higher extraction rate, is safe in operation and easy to control and implement.

Description

Technical field [0001] The invention relates to the technical field of safe processing of solid energetic materials. Background technique [0002] Ammonium perchlorate is a commonly used oxidant and has a wide range of applications in many energetic materials. It is used in the production of propellants and explosives in the national defense industry, and in the production of engraving agents and anti-hail agents for civilian use. Ammonium perchlorate is active in nature and can explode when mixed with reducing agents, combustibles and metal powders. [0003] The solid cloud explosive agent is a kind of fuel-rich high explosive. The solid cloud explosive agent is developed for the shortcomings of the liquid-solid composite cloud explosive agent. The liquid-solid cloud explosive agent has certain fluidity and the density difference among the components Larger, loaded in the missile body, the center of mass is prone to deviation during transportation and storage, which affects the b...

AI Technical Summary

Problems solved by technology

[0006] In the existing technology, the ammonium perchlorate in the solid energetic material is recovered by using the boiling process, and the final extraction rate is between 85% and 90%, but the water temperature is relatively high, and it needs to be heated to about 80°C. For solid cloud explosion For the agent, the operation safety is poor, and the extraction time of this method usually takes more than several hours, and the extraction efficiency is low
