AI Technical Summary
Technical Problem
The existing water suspension method for preparing CL-20/Estane5703 particles suffers from uneven particle size and agglomeration, which affects the safety of the explosive, and the process parameters are difficult to control precisely.
Method used
A pipeline preparation method is adopted, in which CL-20 and Estane5703 solutions are mixed through a spiral glass pipeline to form spherical particles, and uniform coating is formed by diffusion using dichloromethane solvent, thus avoiding the use of surfactants.
Benefits of technology
The CL-20/Estane5703 particles were made uniform in size and regular in morphology, which improved the safety of the explosive and the simplicity of the preparation process, and reduced the probability of impact-sensitive explosion.
