Problems solved by technology

Therefore, the existing delay detonators generally have defects such as inaccurate delay time and poor consistency of delay time, which are limited in use and cannot be used in high-precision controlled blasting
With the development of blasting technology, there is an urgent need to further improve the delay time accuracy of the delayed initiation system, and the existing delay detonators can no longer meet the requirements of high-precision controlled blasting

Abstract

The prodn. method of safety detonator is that conducting wire is connected with detonator body, bottom explosive is put in bottom of detonator, force-end of conducting wire is encapsulated on top of the detonator by elastic PVC plastic plug, an electric time delay unit is connected with force-end of the conducting wire, igniting powder head is connected with out-end of the electric time delay unit. The delay time can be set to 1-30 section with equally interval 20 millisecond, delay error is less than 5 millisecond.

Description

Technical field: [0001] The invention relates to a safety detonator, which belongs to the technical field of detonators. Background technique: [0002] At present, most of the delay detonators used in the prior art use the common agent delay body technology. This technology uses the method of controlling the burning time of the delay agent to obtain the delay time. The delay time error is large, especially for high-level delays. The error of the detonator is as high as hundreds of milliseconds. Even if the newly researched high-precision equal-interval delay agent is used in the delay detonator, the interval of more than 16 segments is 50 milliseconds, the error reaches 40 milliseconds, and the interval of more than 25 segments is 50 milliseconds. 80 milliseconds, the error reaches 60 milliseconds, the higher the segment, the greater the delay time error. Therefore, the existing delay detonators generally have defects such as inaccurate delay time and poor consistency of de...
