Problems solved by technology

For this reason, some technologies add oxidizers to the explosives, but this may reduce the chemical stability of the explosives and reduce production safety.
[0014] Some technologies only include instant detonators, but not millisecond delay detonators, which makes it still impossible for manufacturers of these two detonators to get rid of the primer

example 1

[0038] Example 1: Instantaneous detonator, figure 1

[0039] Such as figure 1 , 1 is a detonator shell, made of steel, copper clad or aluminum, with an outer diameter of 5.7 mm to 8.0 mm, a length of 50 mm to 60 mm, and a thickness of 0.10 mm to 0.38 mm. From the bottom of the detonator to the top, there are mixture 2 of Hesuojin and Taian (the mass ratio of the two is Taian: Hesuojin = 80:20, and the particle diameter is 0.15mm~0.30mm), a closed metal tube at one end 3, and the bottom of the metal tube High explosive 4, high explosive 5 in the middle of the metal tube, high high explosive 6 on the upper part of the metal tube, exciting powder 7, bridge wire type electric ignition powder head 8, and plastic plug 9.

[0040] During production, firstly pack 0.15g to 0.35g of the high explosive 2 mentioned above in the detonator shell, and the density after compaction is 1.2g / cm 3 ~1.6g / cm 3 .

[0041] 3 is a closed steel pipe at one end, which is formed by multiple punching...

example 2

[0044] Example 2: non-electric plastic nonel type prompt detonator, figure 2

[0045] To the steel inner tube being pressed into the detonator shell, the assembly process is the same as example 1, except that plastic nonel tube 8 and stopper 9 are stuck on the detonator shell.

example 3

[0046] Example 3: lead core delay type millisecond delay electric detonator, image 3

[0047] The length of the detonator shell is 65mm-75mm. To press the steel inner tube into the detonator shell, the assembly process is the same as in Example 1. Afterwards, the lead core extension body is pressed into the detonator shell, and then the lead core is clamped outside the detonator shell to fix the lead core. On the lead core delay, stick the gunpowder head plug 10 again, promptly make the lead core delay form millisecond delay electric detonator.

Abstract

The invention relates to the structure, charge and production process of a non-priming charge detonator. The invented non-priming charge detonator includes two types of instant detonators, electric igniter tip and non-electric plastic nonel, and a millisecond delay detonator with a lead core delay body. It stimulates the combustion of gunpowder in the steel pipe to generate high-pressure gas, which acts on the high explosive to make it burn in the steel pipe and develop into a high-speed detonation at the bottom of the steel pipe, thereby making a non-priming detonator. The design is optimized for reliable operation and simple fabrication.

Description

[0001] Technical field: the present invention belongs to the field of detonating equipment, and specifically relates to the structure of the detonator with electric ignition powder head type and non-electric nonel tube type non-priming explosive immediate, lead core delay type millisecond delay detonator, the composition and ratio of explosives and gunpowder contained therein, and the manufacturing process of the entire device. Background technique: [0002] The detonators of the traditional technology are inseparable from the priming charge, which is highly sensitive to external stimuli and can develop from combustion to detonation in a very short time with only a small amount of charge. The strong explosive below the priming charge is detonated by the high-speed detonation shock wave of the priming charge. Primers can be activated by many forms of stimuli, such as the flame from the burning of the primer tip, the flame from the burning of the delay charge, the flame from the...
