Because they contain main explosives, detonators are dangerous for inexperienced persons to handle. Because of their look, they are occasionally misidentified as explosives, resulting in casualties. Dismantling of damaged buildings has caused several accidents due to the presence of hidden detonators.
Detonators are simple devices that when attached to an explosive charge activate the explosive. There are two types of detonators: initiation and impulse. Initiation detonators trigger an explosion by electrical signal or flame. Impulse detonators produce a spark that triggers an explosion. Most commercial demolitions use impulse detonators because they are easier to set off than electrical systems.
Detonators can be divided into three main categories based on how they are activated: pull, push, and contact. Pull-type detonators are attached to a cord that is pulled to activate them. Push-type detonators are pressed down to activate them. Contact-type detonators must make physical contact with another object to activate them. These objects could be switches, magnets, or electrodes.
Pull-type detonators are easy to use but have a short life span because the cord connecting them to the source of electricity will eventually wear out. Push-type detonators are more stable over time but require a firm pressure point to operate.
An electric detonator is any device that contains an initiating or main explosive that is used to trigger detonation in another explosive material by using direct electrical energy from the device's leads (wires, springs, contacts, etc.) to fire an igniter. Electric detonators are used where safety is important in an environment not suitable for conventional detonators, such as within munitions or at remote sites.
The most common type of electric detonator is the hollow-cylinder primer, which consists of two parts: a base and a cover. A spring inside the base presses it against one end of an initiator cord, which passes through both parts and has a second end attached to an electric match. When the match is struck, it sends a current through the cord and into the base, which fires the primer. Some types of electric primers can be fired more than once. After multiple firings, they need to be replaced.
Electric detonators can also be made in other shapes, but the basic idea is the same: a lead wire with a secondary explosive coating inside it called an "ignitor" is pressed against an object containing metal, which completes an electrical circuit that causes the primer to fire.
Some modern anti-personnel mines use electric detonators instead of traditional high-velocity spools and percussion caps.
There was one explosion. A detonation is a sudden and forceful explosion. A supersonic exothermic front accelerates through a medium, eventually driving a shock front that propagates immediately in front of it. Solid and liquid explosives, as well as reactive gases, can all detonate. When this happens, the energy released can cause damage far beyond what would be caused by only considering the initial charge of the explosive. For example, an explosion on board a plane might cause the entire aircraft to disintegrate before any other part of the environment is affected. This type of explosion is called destructive.
The main difference between a detonation and an explosion is speed. In a detonation, the velocity of the wave reaching the end of the blast radius exceeds the sound speed in the material. So instead of hearing waves, you see flashes into darkness. Disintegration of materials occurs because of the high temperature and pressure produced by a detonation. The heat is enough to break down many types of material into its constituent elements (which are then driven away from each other at high speeds). Silicon, for example, will burn in air, but not at a significant rate. However, put it in contact with water vapor at 200 degrees Celsius (392 degrees Fahrenheit) and it will release electrons which can then combine with oxygen to form silicon dioxide (soap) molecules. These molecules are very unstable and will break down further into silicon monoxide and oxygen gas.
This explosion is known as the "popcorn" or "bacon" noise because it sounds like bacon cooking in a skillet. It may also be characterized as someone pounding on the side of the block with a little ball peen hammer. The sound is caused by an internal shock wave that travels through the gas inside the cylinder and into the surrounding air.
The loudest sound I have ever heard was from a firework called a "Roman Candle". The firework had three layers: a wick, a fuse, and an explosive. When lit, the fuse becomes burning and then triggers the explosive which shoots out many small fireworks at once. That night, we were sitting on the beach watching the sunset when there was a huge BOOM! It was so loud that everyone around us ran for cover. After about 10 minutes, people began to look out again and see what happened to our fireworks display. There were still some left but not as many as before because most of them had been blown up by the bomb sound effect!
Bombs can also be made with bottles, jars, or even cars. A car bomb is also known as a "road mine". These are very dangerous objects to play with because they can blow up at any time.
When you hear a big explosion outside this means that someone has just set off a bomb.
Any dynamite, nitroglycerine, black powder, or other comparable explosive substance, including plastic explosives, is considered explosive. Ammunition or ammunition components like as primers, percussion caps, smokeless powder, black powder, or black powder equivalents used for hand loading are not considered explosives. They do not cause damage or destruction when they explode; they only provide force to affect an object with violence.
Bullets are the metal cylinders containing the propellant gas that powers them in flight. The bullet is driven by the explosion of the propellant which is located in a hollow cavity within it. When the bullet leaves the gun, it is propelled at high speed because of the expansion of the gas. As it travels through the air, so too does it break up into many small particles called shrapnel. These sharp pieces of metal can kill or injure people far away from the initial impact site. Bullets are very efficient tools for killing animals and destroying property because of this reason.
People sometimes use the term "bomb" as a synonym for "bullet", but this is incorrect. A bomb is a device designed to produce an explosive effect by mechanical activation, such as by detonation of an internal fuel-air mixture or an external fuse. This distinction is important because not all bullets will detonate if they hit something hard enough. Some types of bullets may even have been designed not to explode when they reach their target.
