Description

technical field [0001] The invention relates to a technology for smoothing energetic material particles, and more specifically, to a device and method for smoothing CL-20 particles. Background technique [0002] With the development of science and technology and the increasingly fierce confrontation of weapons, the smooth processing technology of energetic materials is in the ascendant at home and abroad. Because the smooth treatment of the morphology or structure of energetic material particles can not only effectively improve the fluidity and packing density of energetic materials, but also effectively reduce their mechanical sensitivity and shock wave sensitivity. Therefore, the smooth fine explosive particles will play an important role in practical applications. [0003] CL-20 (hexanitroazaisowurtzitane) is an organic high-energy compound with a density 8% higher than Octogen (HMX), a detonation velocity 6% higher, and an energy density higher than 15%. It will be used...

AI Technical Summary

Problems solved by technology

[0005] There are also reports of using ultrasonic waves to smooth graphite particles, but this method has the disadvantages of high energy consumption and low output

More importantly, this method is difficult to apply to high-sensitivity energetic materials. Due to the penetration of high-intensity ultrasonic energy, it is easy to expand the tiny defects inside the crystal particles, forming cavities / holes inside the crystal particles, giving Energetic material particles pose potential hazards in practical use

[0006] Supercritical fluid technology is a better technology that can be applied to the processing of energetic materials. However, this method has the characteristics of small output and high cost (high production cost and equipment cost), which is not conducive to industrialization and practical application

[0007] For now, recrystallization (including solvent erosion method) is usually used to smooth explosive particles, but recrystallization needs to consume a lot of organic solvents or strong acids, which not only increases the cost, but also is harmful to the health of workers and the environment Protect

More importantly, the explosive particles obtained by the recrystallization method are only particles with a relatively regular crystal form. From a microscopic point of view, there are still edges and corners of the crystal particles at the edges and other positions, and the obtained particles are not real smooth particles.
