What is the oxygen balance of RDX?
–21.6%
Thus, the oxygen balance of RDX is –21.6%.
What is the normal sensitizer in dynamite?
A sensitizer (typically TNT), an oxidizer (ammonium nitrate), water, and a thickener (such as guar gum or starch). An oxidizer solution (typically ammonium nitrate) and oil. Straight dynamite is the benchmark for explosive weight/strength comparisons.
What does an explosive engineer do?
Design and analysis of shaped charges and reactive armor. Design and analysis of military explosives such as shells, aerial bombs, missile warheads, etc. Bomb disposal. Drilling and Blasting.
How are explosives classified?
The term “explosives” shall include all material which is classified as Class A, Class B, and Class C explosives by the U.S. Department of Transportation, and includes, but is not limited to dynamite, black powder, pellet powders, initiating explosives, blasting caps, electric blasting caps, safety fuse, fuse lighters.
What is the oxygen balance of PETN?
Since PETN is a weak negative oxygen-balanced explosive (OB = −10%),42 there is a small amount of CO and H2 formation during thermal instability.
What does RDX stand for?
Royal Demolition eXplosive
Summary: RDX stands for Royal Demolition eXplosive. It is also known as cyclonite or hexogen. The chemical name for RDX is 1,3,5-trinitro-1,3,5-triazine. It is a white powder and is very explosive. RDX is used as an explosive and is also used in combination with other ingredients in explosives.
What is C4 made of?
The explosive in C4 is RDX (cyclonite or cyclotrimethylene trinitramine), which makes up around 91% of C4 by mass. The plasticizer is diethylhexyl (5.3%) or dioctyl sebacate and the binder is usually polyisobutylene (2.1%). Another plasticizer used is dioctyl adipate (DOA).
Can you get a degree in explosives?
The explosives engineering program in the department of mining and nuclear engineering offers the Master of Science (M.S.) degree in explosives engineering for students with bachelor’s degrees in engineering, science or technology.
How long does it take to become a explosive engineer?
High school diploma or equivalent. Less than 5 years work experience. More than 1 year on-the-job training.
What are the 3 categories of high explosives?
High explosives are further divided into initiating, or primary, high explosives and secondary high explosives. Initiating high explosives are very sensitive and are generally used in small quantities in detonators and percussion caps to set off larger quantities of secondary high explosives.
How sensitive is PETN?
Sensitivity testing At room temperature, PETN–PO and PETN–CH have measurably higher sensitivity to impact than the other materials, with drop heights of ∼8 ± 2 cm, using a 2.5 kg drop weight (PETN has an impact sensitivity of 12 ± 2 cm; larger numbers indicate less sensitive materials).
What is explogel V6 watergel?
The Explogel™ V6 middle range energy watergel cartridge combines proven explosive technology with the proprietary Expan™ Ammonium Nitrate technology. The inclusion of Expan™ ensures a product with enhanced sensitivity and energy partitioning for improved advance and generally coarser fragmentation.
What is an explogel™ pillowpak?
Explogel™ Pillowpaks are extensively used in mud blasting and initiated by either 10g/m Zapcord™ or a 6D + detonator.The Explogel™ Pillowpak is produced in one grade, with an energy of approximately 139% (Explogel™ V6) the energy of standard ANFO (Ammonium Nitrate Fuel Oil).
What is the difference between expan and explosmooth™?
The inclusion of Expan™ ensures a product with enhanced sensitivity and energy partitioning for improved advance and generally coarser fragmentation. Explosmooth™ is a very low energy product designed for smooth-wall and perimeter blasting in underground tunnelling and civil engineering excavations.
Why is expan™ V6 watergel cartridge used?
The inclusion of Expan™ ensures a product with enhanced sensitivity and energy partitioning . Explogel™ V6 watergel cartridge is a middle range energy product designed to be used for general mining purposes. in hard rock stoping applications where a higher gas volume is required for increased advance per blast.
