DESCRIPTION
High-strength and high-precision detonator: suitable for underground and open-pit mining. High strength and resistance to physical impact make this product an ideal choice for explosion control in complex blasting applications such as mining, tunneling and infrastructure projects.
Performance
Item | Performance | |
Jolt test | No explosion, structural loose or damage after vibrating for 10mins in the vibration machine | |
Initiating power | Use detonator No.4 to fire through 3mm thick lead plate, or No.8 to fire through 5mm thick lead plate, and the diameter of the hole is bigger than the out-diameter of the shell | |
Oil resistance | Immersed in 0#diesel at 75℃ under 0.3Mpa for 24hrs, put out and initiate, no misfire or incomplete explosion | |
Tensile | Surface detonator | Pull with 19.6N static forces for 1min, shock tube can not be pulled out |
Pull with 78.4 N static forces for 1min, shock tube can not be pulled out | ||
Water resistance | Surface detonator | Immersed in 1m deep water for 8hrs, performance doesn’t change |
In-hole detonator | Immersed in 30m deep water for 20hrs, performance doesn’t change | |
