At present, in the domestic production of explosive composite plates, the detonation method is to use instantaneous detonators to detonate. In order to improve production efficiency, multiple composite plates are used to detonate at the same time. Explosive compounding has the hazard characteristics of open blasting. Harmful phenomena such as explosion shock waves and blasting vibrations increase with the increase in the number of primary explosives. Delayed blasting technology is an effective way to reduce harmful phenomena such as blasting shock waves and blasting vibrations. If the time-delay blasting technology is introduced into explosive composite production, it can effectively reduce the harmful phenomena caused by blasting on the premise of increasing the number of single composites and improving production efficiency. When the time-delay blasting technology is applied in explosive compounding, due to the time difference between the explosive points, the time difference will inevitably affect the quality of explosive compounding.
The full name of the delay electric detonator is "millisecond delay electric detonator allowed in coal mines", referred to as delay detonator; the full name of the instantaneous detonator mentioned is "allowable instantaneous detonator in coal mine", referred to as prompt detonator. Composite explosives are composed of powdery emulsion explosives with explosive diluents added.
In practice, we learned that when the delay time is 25ms, the minimum distance between the boards is 15m; when the delay time is 50ms, the minimum distance between the boards is 30m; when the board spacing is less than the minimum spacing, the composite boards are not well bonded or even not bonded.
In the practice of explosive composite production, when the delay detonator is used for detonation, it is necessary to ensure that the plate spacing is greater than the minimum plate spacing corresponding to the selected delay time. The results show that the delay time is 25ms, the minimum plate spacing is 15m, the delay time is 50ms, and the minimum plate spacing is 30m. There is no obvious difference in quality between the titanium steel composite plates produced by the delayed detonator detonation and the titanium steel composite plates produced by the instant detonator. The performance of the produced titanium-steel clad plate can exceed the shear strength requirement of 137.9MPa in ASTMB898.
It can be seen from the above that different detonation methods have a certain impact on the quality of titanium steel clad plates, and the production requirements of clad plates are very strict.
