Polymer-bonded explosives and plasticizer-coated nitramine based represent a group of energetic materials that have been extensively manufactured in recent years order to satisfy requirements ranging from boosters the main charges warheads. From aspect their production technology, physical-mechanical properties, further detonation it is important properly select incorporate specific functional additives into explosive-polymer matrix. Dioctyl adipate (DOA) predominant plasticizer utilized PBX...

The stability control system for energetic materials during storage involves testing, which need to ensure their reliable performance and over time. Any change in these materials, due compatibility or issues, can cause serious consequences. Therefore, rigorous testing using specific methods is essential the development initial phases conform all required criteria. Composite solid propellants based on ammonium perchlorate (AP)/hydroxyterminated polybutadiene (HTPB)/isophorone diisocyanate...

In the past few years, we have witnessed that due to pandemic and wars, some countries limited their export of various ingredients. The request has been made create a time delay pyrotechnic composition with easily accessible For purpose, black powder addition phenol formaldehyde resin was possible solution. This study aims show an optimization ratio in fuel-oxidant mixture how this influences properties compositions. stoichiometric ratios were determined by using oxygen balance (OB) pyro...

Conventional black powder typically consists of charcoal, sulfur and potassium nitrate (KNO3). The use other carbon-based substances instead charcoal has been less common. Following the development time delay pyrotechnic compositions in this research, properties substances, particularly carbon were studied. widely spread due to its unique chemical composition superior combustion properties. However, specific production process selection materials for producing it is difficult achieve same...

Metal powders have been utilized for a long time in energetic materials to improve some specific performance. In recent years, metal particles reduced size since smaller particles, particularly nano-sized, highly beneficial qualities. These positive aspects are evident the reduction of ignition and combustion times, resulting enhanced volume-constrained systems, improved heat transmission, increased total thermal energy release. Aluminum is one first metals be used form nano-particles...

The main ingredient of gunpowder is nitrocellulose. For slowing down the catalytical decomposition process, predominated stabilizer diphenylamine in use for single-base gunpowder, as well propellants. On other hand, wears out over time, which causes changes chemical stability energetic materials. One classical methods determination Bergman-Jung method, has two subgroups. This paper presents comparative analyses twelve NC and five NCD gunpowder. Namely, both subgroups are based on calculation...

The major energy components of double-based gunpowder are nitrocellulose (NC) and nitroglycerin (NG). In NG is used as a plasticizer and, at the same time, an energetic component. Since amount in strongly influences affects its chemical mechanical properties or/and characteristics, study content great importance. aim this paper to compare analytical performances high-performance liquid chromatography (HPLC) classic volumetric method for separation qualitative determination nitroglycerine...
