Detailed Product Description
Uses: High-Precision Shock Tube Series Delay Detonator is suitable for blasting work in coal mine or in open pit where present no fire damp or coal dust. Especially suitable for large diameter holes and deep holes blasting work by filling high temperature emulsion explosive oil in a mixture drug vehicle. It is free from stray current and static electricity effects.
Features: It can realize hole-by-hole millisecond blasting work and directional blasting work with high-precision millisecond delay and reliable ignition initiation. It is easy to connect detonators into network with connectors. The operation is much easy in the construction process. It can meet high temperature resistance and high strength requirements. The blasting vibration is smaller; flying rocks are reduced; side impact and back impact are smaller and blasting pile is concentrated, etc. Blasting work can be done completely and boulder yields can be lowered. That improves productivity effectively and lowers blasting cost as well.
Performances:
Initiating power: ≥No.8 detonator
Ground-surface delay detonator standard time: 9ms, 17ms, 25ms, 42ms, 67(65) ms, 100ms;
In-hole delay detonator standard time: 375ms, 400ms.
Temperature Resistance: The initiating power should not be changed at -45~80.
Stretch Resistance: Stretch resistance is not less than 196N at 15~25.
Oil Resistance: Immersed in No.0or No.-35 diesel oil at 75~80, after 72 hours of natural cooling, initiating power should not be changed.
Water proof: Immersed in water of 30m deep for 24 hours, the initiating power should not be changed.
