Embodiment 1

[0017] Embodiment 1: GTG primer safety detonator

[0018] In the detonator shell with a length of 50mm, firstly, 300mg of shellac granulated RDX (RDX) explosive is loaded, and the shellac granulated RDX is pressed into a powder column with a pressure of 80MPa, and then 300mg of lac granulated black powder is loaded. Suojin Explosive uses a pressure of 60MPa to press shellac granulated black Suojin into a powder column; then load 200mg of crystalline Taian explosive (PETN), and then pack 180mg of perchloric acid tricarbonyl hydrazide cadmium (GTG) primer, Buckle up the reinforcing cap, press down the reinforcing cap with a pressure of 20 MPa, and at the same time compress GTG and PETN tightly to fill the intrinsically safe basic detonator with GTG as the priming charge.

[0019] Insert the ordinary fuse into the detonator, and after the fuse is ignited, the burning fuse cannot detonate the detonator; directly inserting the electric ignition charge, the detonator cannot be deton...

Abstract

The invention discloses an essentially safe detonator for civil use or engineering blasting. According to the safe detonator, a perchlorate carbon hydrazide complex is served as an initiating explosive; and the pressure switching effect exists in the deflagration to detonation transition process of such initiating explosives, so that the deflagration to detonation transition process can be realized reliably in an airtight state of sealing the detonator, thereby outputting detonation waves; and the deflagration to detonation transition process cannot be realized in a pressure relief state of opening the detonator. Therefore, the detonator only utilizing the initiating explosive has special use safety and reliability and can be assembled together with the electric ignition components of an electric heating wire, magnetoelectric ignition components, the ignition control components of an electronic circuit or the ignition components of an explosive-guiding pipe to form a safe electric detonator, a safe magnetoelectric detonator, an essentially safe electronic detonator or a safe explosive-guiding detonator so as to be used for civil blasting equipment. As a result, accidental explosion accidents are controlled effectively as well as terrorist events are prevented.

Description

technical field [0001] The invention discloses a safety basic detonator technology, where the safety basic detonator can be assembled with electric heating wire electric ignition components, magnetoelectric ignition components, electronic circuit control ignition components, nonel tube ignition components to form an electric detonator , Magnetic detonator, electronic detonator, detonator detonator general. Background technique [0002] Basic detonators are the basic components for manufacturing industrial electric detonators, electronic detonators, and nonel detonators. In order to realize the detonation wave output function of the detonator after ignition and detonation, it is necessary to use a detonating agent that is very easy to achieve combustion to detonation, such as dinitrodiazonium phenol (DDNP), lead azide (LA), styphenolic acid Lead (LTNR), etc. These primary explosives are highly sensitive and dangerous, and can burn and explode as long as they encounter spark...
