Use Forms Of Explosives
Explosive materials are produced in numerous physical forms for their use in mining, engineering, or military applications. The different physical forms and fabrication methods are grouped together in several use forms of explosives. Explosives are sometimes used in their pure forms, but most common applications transform or modify them. These use forms are commonly categorized as: Castings Castings, or castable explosives, are explosive materials or mixtures in which at least one component can be safely melted at a temperature which is safe to handle the other components, and which are normally produced by casting or pouring the molten mixture or material into a form or use container. In modern usage, Trinitrotoluene or TNT is the basic meltable explosive used in essentially all castable explosives. Other ingredients found in modern castable explosives include: * Active, energetic or explosive ingredients: ** Aluminum powder ** Ammonium nitrate ** Ammonium picrate ** Bariu ...

Detasheet
Detasheet is a flexible rubberized explosive, somewhat similar to plastic explosives, originally manufactured by DuPont. Its ingredients are PETN with nitrocellulose and a binder. Properties It was manufactured in thin flexible sheets with a rubbery texture, technically known as a rubberized explosive and is generally colored either reddish/orange (commercial) or green (military). In use, it is typically cut to shape for precision engineering charges. Compared to other explosives detasheet is very stable. It is detonated with a blasting cap or primercord but not by small-arms fire, heat, water, pressure, or concussion. Detasheet is relatively expensive compared to other explosives. Ingredients Detasheet C, the last and most common version produced, was made up of 63% PETN, 8% nitrocellulose, and 29% acetyl tributyl citrate (ATBC), an organic plasticizer. Production status DuPont ceased manufacturing explosives in the 1990s and when they did the Ensign-Bickford Aerospac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheet Explosive
Sheet explosives are materials formed by combining an explosive with a "rubberizer"—a flexible binding agent. The resulting compound is cast into a flat sheet which is typically pliable and deformable over a wide range of temperature. Typical products are generally shock-insensitive secondary explosives, requiring a blasting cap or other detonator. Detonation velocities are frequently very high, which can improve the detonation synchronicity across the area of a tertiary charge with a low detonation velocity. This property makes them suitable for use in detonation trains which require precise timing and homogeneous delivery of force across a complex surface (but see also shaped charge for an orthogonal technique). Applications: As a main charge Magnetic flux compression generator In an explosively-pumped magnetic flux compression generator, explosives are used to accelerate the plates of a large capacitor at each other, while the capacitor has a charge. The result is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PETN
Pentaerythritol tetranitrate (PETN), also known as PENT, PENTA, (ПЕНТА, primarily in Russian) TEN, corpent, or penthrite (or, rarely and primarily in German, as nitropenta), is an explosive material. It is the nitrate ester of pentaerythritol, and is structurally very similar to nitroglycerin. Penta refers to the five carbon atoms of the neopentane skeleton. PETN is a very powerful explosive material with a relative effectiveness factor of 1.66. When mixed with a plasticizer, PETN forms a plastic explosive. Along with RDX it is the main ingredient of Semtex. PETN is also used as a vasodilator drug to treat certain heart conditions, such as for management of angina. History Pentaerythritol tetranitrate was first prepared and patented in 1894 by the explosives manufacturer Rheinisch-Westfälische Sprengstoff A.G. of Cologne, Germany. The production of PETN started in 1912, when the improved method of production was patented by the German government. PETN was used by the Germ ...

Ensign-Bickford Company
The Ensign-Bickford Aerospace & Defense Company (formerly The Ensign-Bickford Company) is a manufacturer of hardware and energetic systems for use in spacecraft, military, and industrial applications. It is a wholly owned subsidiary of Ensign-Bickford Industries. History The Ensign-Bickford Company (EBCo) was started in 1836 in Simsbury, Connecticut as a manufacturer of William Bickford's safety fuse for use in mining. Safety fuse was a great advance in mining technology over the practice of filling holes with black powder. The next step in mining technology was detonating cord. Ensign-Bickford and other companies developed different versions of detonating cord. In 1937, Ensign-Bickford trademarked "Primacord", which became the functional generic name for detonating cord in North America. In May 2003, Ensign-Bickford sold the trademarks and processes to Dyno Nobel Inc of Australia (formerly of Norway). In 1956, EBCo began providing research and development work for Fran ...

Nitrocellulose
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications. In the form of collodion it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. Production The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The quality of the cellulose is important. Hemicellulose, lignin, pentosans, and mineral salts give inferior nitrocelluloses. In precise chemical terms, nitrocellulose is not a nitro compound, but a nitrate ester. The glucose repeat unit (anhydroglucose) within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the raw material during fabrication, or to meet the demands of the end product's application. For example, plasticizers are commonly added to polyvinyl chloride (PVC), which otherwise is hard and brittle, to make it soft and pliable; which makes it suitable for products such as shower curtains, vinyl flooring, clothing, bags, flexible plastic tubing, and electric wire insulation/coating. Plasticizers are also often added to concrete formulations to make them more workable and fluid for pouring, thus allowing the water contents to be reduced. Similarly, they are often added to clays, stucco, solid rocket fuel, and other pastes prior t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C-4 (explosive)
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical. C-4 has a texture similar to modelling clay and can be molded into any desired shape. C-4 is relatively insensitive and can be detonated only by the shock wave from a detonator or blasting cap. A similar British plastic explosive, also based on RDX but with a plasticizer different from that used in Composition C-4, is known as PE-4 (Plastic Explosive No. 4). Development C-4 is a member of the Composition C family of chemical explosives. Variants have different proportions and plasticisers and include compositions C-2, C-3, and C-4. The original RDX-based material was developed by the British during World War II and redeveloped as Composition C when introduced to the U.S. military. It was replaced by Compositio ...

Explosives
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
