Low explosives deflagrate while high explosives detonate. low explosives have slower reactions, are used as propellants (produce pushing effect), and must be confined in container to explode (otherwise it would burn). high explosives have faster reactions, the shockwave causes the damage, it produces a "shattering" effect, more stable.

Explosions and Explosives: Explosion: An explosion occurs after a chemical reaction when a large amount of energy is created in a short space of time. This energy comes in the form of heat and usually lots of gas. As the reaction occurs so quickly, the gases do not expand immediately but when they do create an enormous ‘blast wave’ which can cause a lot of damage to surroundings.
Associated with the detonation of an explosive is a fireball.

In general, the dimension of the fireball is given by: D = x W Where W is the weight of the explosive in pounds and D is the diameter of the fireball in feet. So, for example, if there is an explosion of 10 pounds there will be a.
There is no information on dermal and ocular toxicity in humans following exposure to fuel vapors. To assess the potential toxicity to the eyes and skin following exposure to the vapors without those data, the subcommittee used information on the dermal and ocular toxicity following application of total fuel to the skin and eyes or dermal injections, largely in experimental animals.

Most explosives are used in 2- 3- or 4-step trains that are shown schematically in Figure The simple removal of a tree stump might be done with a 2-step train made up of an electric blasting cap and a stick of dynamite.

Explosives fall into several categories; however, the foci of this work are nitramine explosives including Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and. Engines used for different types of service require fuels with specific chemical and physical properties, and individual specifications have evolved to meet those cial and military fuels 1 are made by blending kerosene fractions with low-boiling-point fractions containing more-volatile hydrocarbons.
Except for the additives, the chemical composition of most military fuels is.

CanmetCERL Explosives Lab CanmetCERL (Canadian Explosives Research Laboratory) within the Explosives Safety and Security Branch of the Lands and Minerals Sector at NRCan is the only Canadian government laboratory dealing with commercial explosives, and one of the few in the world.

Ammonium Nitrate a. aqueous solutions containing less than 60% weight in weight of ammonium nitrate b. any material in soli d form comprising a mixture of components, one of which is ammonium nitrate, where the nitrogen content derived from ammonium nitrate is less than 28% by weight of.
It's not surprising that the federal government has a few regulations regarding the use of explosives in mining: 30 CFR, Part 15 (approval of explosives and sheathed explosive units): 30 CFR P Subpart E (safety and health standards: surface metal and non-metal mines: explosives); 30 CFR P Subpart E (safety and health standards: underground metal and nonmetal mines: explosives.
necessarily heat- light- friction- or shock-sensitive. These chemicals give off gaseous degra-dation by-products that may cause over-pressurization of the container and explode. They can degrade over time and should be incorporated into a safety and handling system that will prevent them from becoming explosive Size: KB.

Obviously avoiding nuclear weaponry, what are the most powerful conventional explosive materials. My original question was see what you could theoretically replace the modern military's HMX based explosives with. That said, feel free to bring up theoretical and hypothetical materials in the interest of.
Preliminarily results on the reaction mechanism of detonation of composite emulsion explosives sensitized by MgH2, which simultaneously plays the role of an energetic material, are presented.
Compared to emulsion explosives sensitized by glass microspheres, emulsion explosives sensitized by magnesium hydride have a different reaction mechanism of by: Leading worldwide specialist in the field of high explosives, EURENCO offers its customers a complete range of high explosives and compositions like HNS, owing to high-tech manufacturing capabilities.
