In this study, nitrated bacterial cellulose (NBC) energetic binder was introduced to prepare NBC-based nanocomposite materials (nEMs) through a combined simple and safe sol–gel method the freeze-drying technology. A series of analytical test methods were systematically conducted characterize structure, composition, thermal properties, safety performance materials. The results indicated that particles nitramine explosives dispersed embedded homogeneously in three-dimensional (3D) porous...
The properties of gun propellants are important for the stability weapon systems and have been extensively studied in field research. In this work, an applied semi-solvent method was used to prepare a triple base propellant with nitrated bacterial cellulose (NBC)/nitrocellulose (NC) as binder system. For first time, study found that addition NBC system resulted distinct spatial 3D network structure. morphology, composition, mechanical properties, energy, thermal behaviour, combustion...
Abstract In order to investigate the thermal decomposition kinetics and mechanism of nitrocellulose (NC) based nitramine explosives nanocomposite energetic materials, this work prepares NC/RDX (cyclotrimethylenetrinitramine), NC/HMX (cyclotetramethylenetetranitramine), NC/CL‐20 (hexanitrohexaazaisowurtzitane) composites by a combined sol‐gel freeze‐drying technology. The structure is systematically investigated results reveal that explosive particles are dispersed, filled, or embedded...
Abstract In this work, nitrocellulose/hexanitrohexaazaisowurtzitane/carbon nanomaterials (NC/CL‐20/CnMs) nanoenergetic composite materials are synthesized by combining sol‐gel and vacuum freeze‐drying technology, wherein NC is chosen as the gel matrix to load CL‐20 particles CnMs. The results indicate that CnMs imbedded homogeneously dispersed in monolithic of matrix, polymorph maintains optimal ϵ form during fabrication process. thermal reveal onset temperature exothermic visibly advanced...
Abstract In this paper, an SF‐3 double‐base propellant was treated by a supercritical carbon dioxide foaming process. Effects of the pressure on morphology, energy level, and ingredients foamed detonation performance perfusion explosive with were studied. Results show that, increase pressure, number pores in gradually increased, some connected to form small amount cracks. process, had effect SF‐3, formation dense increased volume sample. The acted as “hotspots” during process explosive,...
This paper used a supercritical CO2 batch foaming process to treat waste SP double-base propellant, which is type of propellants containing 58.6% nitrocellulose, 40.0% nitroglycerin, 0.8% centralite, and 0.5% vaseline, solve problem poor stability industrial explosives directly prepared by the propellant. Experiments show that this can produce dense pores inside With increase pressure CO2, number foamed propellant increased, these served as hotspots in detonation reaction. An increased...
