摘要
Abstract
In order to improve the crystal quality of HATO and promote its safety performance in the application of explosives,the solubilities of HATO in four pure solvents and three mixed solvents were measured by the equilibrium method,and the re-crystallization solvent system of HATO was optimized.By using cooling recrystallization method,high-quality HATO crystal was prepared by controlling the type of solvent,cooling rate,and stirring rate.The Materials Studio software was used to sim-ulate the binding ability of HATO with several common adhesive materials,and the materials with strong binding ability with HATO were selected for further coating.The mechanical sensitivities of HATO before and after coating were also tested.The results show that HATO has a higher solubility in the water-formic acid system,but the water-ethanol system is more favorable to the sphericity of HATO.The density of HATO crystal obtained by cooling recrystallization is 1.87 g/cm3,the 5 s bursting point is 286.12℃,the detonation velocity is 9 550m/s,the impact sensitivity and friction sensitivity are 24％and 16％,re-spectively.The above performances are better than those of raw material HATO.The cohesion energy density of fluorine-con-taining materials and HATO is higher than that of non-fluorine-containing materials,proved that fluorine-containing materials has a stronger adhesion effect on HATO.The coated HATO has no crystal face exposed,and the mechanical sensitivity is signifi-cantly reduced.关键词
