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).
Is RDX impact sensitive?
The high-quality RDX exhibited a high purity (≥99.90%), high apparent density (≥1.811 g/cm3), spherical shape, and relatively low impact sensitivity (6%).
What is Cap sensitivity?
Cap sensitivity is a measure of the minimum energy, pressure, or power required for initiation of a detonation; i.e., “cannot be detonated by means of a No. 8 test blasting cap when unconfined.” Strength Two strength ratings are used for commercial dynamites.
Which chemical used to make explosives is sensitive to friction impact and static electricity?
Ammonium powder can be purchased at paint stores. This explosive is sensitive to friction, impact, and static electricity and needs only a blasting cap for initiation.
What is PETN used for?
Pentaerythritol tetranitrate (PETN) is an explosive used as the primary ingredient in detonating fuses and as a component in some plastic explosives.
What is the military use for RDX?
As a military explosive, RDX can be used alone as a base charge for detonators or mixed with another explosive such as TNT to form cyclotols, which produce a bursting charge for aerial bombs, mines, and torpedoes (HSDB 2009; Lewis 2000; Sax and Lewis 1989; Stokinger 1982).
How RDX is detected?
Several methods have been used to detect and measure RDX in explosive materials and debris from explosions. The most common separation procedure is HPLC, but HRGC has also been used. These methods have been paired with several types of detectors, including TEA, MS, electrochemical detection, and UV.
Why is it called RDX?
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.
Why is RDX mixed with TNT?
❖ RDX can be used alone as a base charge for detonators or mixed with other explosives such as TNT to form Cyclotols, which produce a bursting charge for aerial bombs, mines and torpedoes (ATSDR 2012; Lewis 2000).
What is the full form of RDX and TNT?
Among the different explosives developed during this period were TNT (2,4,6-trinitrotoluene), RDX (Research Department Explosive or hexahydro-1,3,5-trinitro-1,3,5-triazine), PETN (Pentaerythritol tetranitrate) and HMX (High Melting Explosive or octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) are to name only a few.
What is sensitivity analysis?
Sensitivity Analysis is a tool used in financial modeling to analyze how the different values of a set of independent variables affect a specific dependent variable under certain specific conditions. In general, Sensitivity Analysis is used in a wide range of fields, ranging from biology and geography to economics…
How do you perform a sensitivity analysis in Excel?
This question is answered with sensitivity analysis. The analysis is performed in Excel under the Data section of the ribbon and the “What-if Analysis” button, which contains Goal Seek and Data Table. These are both taught step by step in our free Excel Crash Course.
Is asphalt-contaminated TNT more impact sensitive?
Asphalt-contaminated TNT was somewhat less impact sensitive than pure TNT at temperatures of -110 to 125oC, but became more sensitive at 130oC; 50 pct probability of initiation at a drop height of 7.8 cm at 110oC, decreasing to 3.3 cm at 130oC.
