Safe extraction method for ammonium perchlorate in solid fuel air explosive

Abstract

The invention relates to the technical field of safe treatment of solid energetic materials and particularly discloses a safe extraction method for ammonium perchlorate in a solid fuel air explosive. The method includes the steps that the powdery solid fuel air explosive containing ammonium perchlorate and a certain amount of water and surfactant are mixed to be uniform, wherein the use amount of the surfactant is 1%-4% of the weight of the solid fuel air explosive; an ultrasonic extraction device is used for ultrasonically extracting mixed feed liquid at room temperature, and ammonium perchlorate is extracted into a water solution; the surfactant is Tween series nonionic surfactant. The method can be used for recycling ammonium perchlorate in the solid fuel air explosive at normal temperature, the extraction time is obviously shortened, the extraction efficiency is obviously improved, the higher extraction rate is achieved, 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
