Scope of application
Can reliable initiation each kind of industrial explosive, detonating cord, detonating tube. Suitable for no combustible gas or dust explosion hazard situation of blasting operation.
Main performance indicators
Execution standard: GB8031-2005
1, resistance: 2 m long copper crural line resistance is not greater than 4.0 Ω, upper and lower deviation is not more than 1.0 Ω; 2 m long galvanized steel reinforced crural line resistance is not greater than 6.3 Ω, upper and lower Ω difference is not greater than 2.
2, initiating ability: can you pierced the lead plate thickness is 5 mm, perforation diameter should not less than detonator outside diameter.
3, delay time to comply with the provisions of the standard.
4, water resistance, into the water pressure is 0.01 MPA, keep 1 h, then remove ignition test, should be completely.
5, and heat resistance performance: keep 4 h in 100 ℃ environment should not be an explosion.
