DETONATING CORD Meaning and
Definition
-
Detonating cord, also known as detonation cord or det cord, is a specialized explosive device primarily used for initiating larger explosive charges in a controlled manner. It consists of a flexible plastic or textile core that is filled or coated with a high explosive material, typically PETN (pentaerythritol tetranitrate) or RDX (cyclotrimethylenetrinitramine).
The purpose of a detonating cord is to transmit a shockwave capable of initiating other explosive materials, such as dynamite or a larger explosive charge. It is designed to propagate a fast and reliable detonation along its entire length when initiated at one end. The detonation wave typically travels at around 6,000 to 8,000 meters per second, ensuring uniformity and precision in blasting operations.
Detonating cords are commonly used in various industries, including mining, construction, and demolition, as they offer a safer and more efficient method of initiating controlled explosions. They are often used in combination with timing devices or blasting caps to synchronize the detonation of separate charges or to achieve specific blasting patterns.
The use of detonating cords requires strict adherence to safety procedures, as they are highly sensitive and pose a significant risk if mishandled or misused. Precise measurements, secure storage, and professional knowledge are fundamental for proper handling and application.
In summary, a detonating cord is a specially designed explosive device utilized to initiate larger charges in a controlled manner by transmitting a rapid and reliable shockwave along its length.
Etymology of DETONATING CORD
The word "detonating cord" has a straightforward etymology based on the meanings of its individual parts.
- "Detonating" originates from the verb "detonate", which means to explode or cause an explosion. It comes from the Latin word "detonare", where "de-" implies a reversal or intensification of action, and "tonare" means to thunder.
- "Cord" refers to a flexible string or thin rope made of multiple strands twisted together. It can be traced back to the Latin word "chorda", which means a string or rope.
Combining these two words, "detonating cord" refers to a type of cord or string that is specifically designed to explode or cause an explosion when ignited.
