What is an example of a secondary high explosive?

What is an example of a secondary high explosive?

Secondary explosives are used in larger quantities in an explosive train and are usually initiated by a smaller quantity of a primary explosive. Examples of secondary explosives include TNT and RDX.

What is secondary explosion?

A secondary explosion occurs when an explosion within a process has not been contained or suppressed by the explosion protection systems enabling the initial explosion to disturb product built up on the external surfaces, thus allowing the product to form a dust cloud and be ignited by the primary explosion.

What is the main difference between primary and secondary high explosives?

Primary explosives detonate by ignition from some source such as flame, spark, impact, or other means that will produce heat of sufficient magnitude. Secondary explosives require a detonator and, in some cases, a supplementary booster. A few explosives can be both primary and secondary…

What are two types of high explosives?

High explosives will be referred to Type E explosives, and there will be three sub-types in this group:

• 1 – blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
• 2 – perforating explosives (intended for use in the oil and gas well industry);

Which is better secondary explosives or primary explosives?

Secondary explosives are less reactive to shock and friction than primary explosives, which make them less dangerous and easier to handle.. They are paired with primary explosives, for ignition when utilized. Done in this manner, the explosion can be calculated and controlled to avoid mishap.

What are the names of the high explosives?

Nitroglycerine, trinitrotoluene, and RDX are high explosives. Los Alamos National Laboratory is engaged in important research into high explosives and has been recognized for making them environmentally cleaner and more stable, which means safer.

How does the detonation of a high explosive work?

High explosives consist of materials that typically combine the reacting elements in the same molecule. This allows them to react much faster, and they “detonate.” Detonation involves supersonic shock waves that pass through the material, causing chemistry that happens quite a bit faster than burning.

How are explosives susceptible to initiation by flame?

According to the deflagration-to-detonation test, soils containing more than 12% secondary explosives by weight are susceptible to initiation by flame; according to the shock gap test, soils containing more than 15% secondary explosives by weight are susceptible to initiation by shock.
