APPARATUS FOR FORMING FINE PARTICLE OF CHEMICALLY COMBINED EXPLOSIVE, APPARATUS FOR MANUFACTURING CHEMICALLY COMBINED FINE PARTICLE EXPLOSIVE, AND METHOD FOR MANUFACTURING CHEMICALY COMBINED FINE PARTICLE EXPLOSIVE

摘要

PROBLEM TO BE SOLVED: To facilitate the controlling of the particle shape and the particle size of a chemically combined fine particle explosive when performing the recrystallization of the chemically combined explosive using a supercritical CO2.

SOLUTION: There are provided a first conduit that introduces a solution of the chemically combined explosive being dissolved in an organic solvent, and a second conduit that is arranged coaxially with the first conduit and so as to surround the first conduit and that introduces the supercritical CO2, wherein the exit end of the second conduit is longer than the exit end of the first conduit by 5 mm or more, whereby the second conduit forms a single flow channel for performing the recrystallization of the chemically combined explosive by contacting the supercritical CO2with the solution. In the single flow channel the second conduit has the same inner diameter and a length of 5-200 mm. When the pressure within the second conduit reaches to a given pressure during introducing the supercritical CO2into the second conduit, the solution is introduced into the first conduit and in the single flow channel the recrystallization to the chemically combined fine particle explosive having a spherical shape is occurred by contacting the supercritical CO2with the solution, and the recrystallized chemically combined fine particle explosive is recovered.
