“…25–27 Recent experiments reported that the more gas generated by decomposition before thermal runaway, the greater the pre-damage caused and the lower the reaction intensity of slow cook-off. 28–31 Since the explosives rapidly combust and explode after entering from thermal decomposition to thermal runaway, the thermal pre-damage before this significantly influences the intensity of the reaction. Therefore, we used an adiabatic reaction calorimeter (ARC) to investigate the heat and gas release behaviour of HMX and PW/HMX between decomposition and thermal runaway.…”

A cook‐off resistant high‐energy booster explosive based on hexanitrohexaazaisowurtzitane (CL‐20) and 1,1‐diamino‐2,2‐dinitroethylene (FOX‐7) was prepared by the solvent‐slurry process with ethylene‐vinyl acetate copolymer (EVA) and acrylate rubber (ACM) as binders. Small‐scale cook‐off test was used to select formulations that have cook‐off resistant ability and their performance were further compared. Scanning electron microscopy (SEM) was utilized to characterize the morphology and particle size of CL‐20, FOX‐7 and molding powders. The mechanical sensitivity, thermal decomposition performance, and detonation velocity of the CL‐20/FOX‐7 boosters were also measured and analyzed. The results showed that the mechanical sensitivity of CL‐20/FOX‐7 boosters was significantly lower than those of CL‐20 based PBX without FOX‐7. The maximum measured detonation velocity of the booster is 8576 m ⋅ s−1. These combined properties indicate that CL‐20/FOX‐7 booster can be used as an insensitive booster.

A number of coating techniques have been used to improve the processability of high explosives. These techniques are typically used for developing compositions, such as boosters and fillers. The most typically used technique is the “solvent–slurry coating”. Several compositions of polymer-bonded explosives have been industrialized using this technique. The NUPC-6 polymer-bonded powder composition of hexahydro-1,3,5-trinitro-1,3,5-triazine is optimized using the solvent–slurry coating. It involved multiple processes, i.e., preparing a slurry of high explosives in an aqueous phase, dissolving the modified polymer binder in an organic solvent, maintaining both the solvent and slurry at controlled temperatures, introducing polymer binder solution and ingredients in the slurry, distilling the solvent, mixing contents homogeneously, filtering the polymer-coated hexahydro-1,3,5-trinitro-1,3,5-triazine composition, and drying in a vacuum oven. The phlegmatizing and hydrophobic agents enhance flowability and hydrophobicity. The mass flow rate, bulk density, tapped density, compressibility index, and Hausner ratio are determined to evaluate its flowability during filling operations. The results show that the composition is flowable using a filling funnel, with a 150 mm upper diameter, 25 mm flow diameter, and 136 mm total funnel height. The raw polymer binder was modified using diisooctylsebacate and SAE-10 oil. The additives in the composition enhance its flowability, and it might be used in underwater applications.
