Problems solved by technology

However, since the marking information is set on the outer surface of the detonating tube, it is easy to be worn and erased during the circulation and use of the detonating tube, so the reliability of this method of setting the marking information is extremely poor, and it is impossible to accurately and reliably identify the detonating tube. source, which is not conducive to product quality control, accident accountability and the supervision of civilian blasting equipment
[0004] How to overcome the deficiencies in the existing technology and solve the problem that nonel products can be accurately identified before and after use has become a major problem in the field of civil blasting equipment today.

Abstract

The invention relates to a method for manufacturing and detecting an identification detonator used for engineering detonation. The identification detonator comprises a plastic shell (1) and a detonating powder (2), which is characterized in that an inertia tracer (3) is added in the detonating powder (2), the mixed powder is uniformly adhered to an inner wall of the plastic shell (1), the inertiatracer (3) is one or more powder mixtures selected from metal oxide or carbonate. The method for manufacturing and detecting the identification detonator comprises the following steps: the prefabricated mixed powder containing the detonating powder (2) and the inertia tracer (3) in a plastic stay tube is uniformly adhered to the inner wall of the plastic shell (1), then prepared identification detonator enables detection of medicine components, compared with the medicament formula information in database, the qualified product is the finished product of the identification detonator. The identification detonator possesses characteristic of traceablility, and can provide reliable approach and support for product quality control and accident responsibility investigation.

Description

technical field [0001] The invention belongs to the field of civil blasting equipment, in particular to an identification nonel used for engineering detonation and a manufacturing and testing method thereof. Background technique [0002] Safe production, safe storage, safe use and safety supervision in the field of civil blasting materials are the top priority to promote the development of this field. In particular, the lagging of safety supervision measures directly restricts the rapid development of this field. Countries all over the world attach great importance to this Expansion and improvement of safety supervision means. Plastic detonating tube, referred to as nonel for short, is an important civilian blasting equipment. It uses polyethylene resin as the pipe material, and the inner wall of the pipe is adhered with a detonating charge, and its components mainly include high explosives (hersokine or octokin) and aluminum powder. The detonating tube can transmit the de...
