Product Description

Overview
Seismic exploration electric detonators are composed of wires and foundation detonators, which are suitable for detonating various seismic source bombs to investigate geological structure and mineral distribution; they can also be used for blasting projects in underground or open-air places without gas and dust explosion hazards.

performance index
● Initiation ability: it can burst through a lead plate with a thickness of 5mm, and the perforation diameter of the lead plate shall not be less than the outer diameter of the detonator.
● Tensile performance: the product shall last for 1min under the static tension of 19.6N, and the sealing plug and foot line shall not be damaged or moved visually, and shall be reliably detonated.
● Water resistance: the product is immersed in 0.3MPa (equivalent to 30m) water, kept for 72h, and reliably detonated after being taken out.
● Maximum non-ignition current: apply a constant DC current of 0.2A for 5min without explosion.
● Minimum ignition current: the minimum ignition current of the detonator is not greater than 0.45A.
● Series initiation current: when 20 detonators are connected in series, 3.5A constant DC current shall be applied for 20ms, and all detonators shall be fired.
● Antistatic: capacitor 500pF, series 5kΩ resistor, voltage 25KV, the detonator foot-shell discharge should not explode.
● RF resistance: in line with GJB151A/152A-97 standard RS103 10KHz ~ 18GHz electric field radiation sensitivity requirements.

Method of use
Before use, the detonator resistance shall be checked one by one in the explosion-proof protective facilities. The working current of the instrument used shall not be greater than 0.03A. The open-circuit detonator shall short-circuit the wire tail and be destroyed in time.
When blasting in groups in series, the detonator foot line should be connected first, and finally connected with the wire of the power supply.

Precautions
● When transporting, it should be handled with care, and friction and impact are strictly prohibited.
● Keep away from fire and heat sources to prevent sun, rain and moisture.
● When using, the resistance should be detected in the protective facilities, and the detection current should not exceed 0.03A.
● It is forbidden to use the detonator as a drilling tool.
● This product shall not coexist with explosives, detonating cord and seismic source charge.
