Safe extracting method of ammonium perchlorate in solid FAE (Fuel Air Explosive)

Abstract

The invention relates to the technical field of safe treatment of solid energetic materials, and particularly discloses an extracting method of ammonium perchlorate in solid FAE (Fuel Air Explosive). The extracting method comprises the following steps: uniformly mixing a powdery solid FAE containing the ammonium perchlorate with a certain amount of water and surfactant, wherein the dosage of the surfactant is 1 to 4 percent of the weight of the solid FAE; carrying out ultrasonic extraction on mixed liquid by using an ultrasonic extraction device under room temperature, wherein the ammonium perchlorate is extracted into a water solution, and the surfactant is a brominated quaternary ammonium cationic surfactant. According to the extracting method disclosed by the invention, the ammonium perchlorate in the solid FAE can be recycled under normal temperature, the extracting time is remarkably shortened, the extracting efficiency is remarkably increased, a higher extracting rate is obtained, the operation is safe, and control and implementation are easy.

Description

technical field [0001] The invention relates to the technical field of safe handling of solid energetic materials. Background technique [0002] Ammonium perchlorate is a commonly used oxidant, which is widely used in many energetic materials. It is used in the production of propellants and other explosives in the defense industry, and in the production of engraving agents and anti-hail agents for civilian use. Ammonium perchlorate is active and will explode when mixed with reducing agents, combustibles and metal powders. [0003] Solid cloud blasting agent is a kind of high explosive rich in fuel. Solid cloud blasting agent is developed for the deficiency of liquid-solid composite cloud blasting agent. Liquid and solid cloud explosive agent has certain fluidity, and the density difference between components Larger, loaded in the projectile body, prone to center of mass deviation during transportation and storage, affecting ballistic accuracy and explosive performance stabi...

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
