1, applies to non-flammable gas or hazardous work environment without blasting dust explosion;.
2, applies to the strict requirements of precision delay blasting;
3, for underwater blasting or surface water working industry;
4, can be reliably detonate a variety of industrial explosives, detonating cord and detonating pipe.
Key performance indicators:
Standard: "digital electronic detonator" (Q / 74691619-7.1-2011)
1, the delay time range: 0 ~ 16000ms interval can be set. Extended range at 100ms or less, the deviation should be less than 1ms, extension range at the time of 101ms or more, the relative deviation should not exceed 1% of the value of the preset delay time.
2, seismic performance: the vibration test machines, continuous vibration 10min, shaking process should not explode, loose or damaged phenomenon; after shock is completed, should be able to properly detonate.
3, anti-DC voltage: feet between the product lines apply 65V DC voltage, power-on time 10s, not an explosion.
4, electrostatic sensitivity: the capacitance of 2000pF, series resistance of 0Ω and charging voltage at 8kV condition, the product of the foot line - foot line, foot line - shell discharge, detonator explosion should occur.
5. Initiating Capacity: The product should be able to wear a 5mm thick fried stereotype, perforation diameter should be no smaller than the outer diameter of the detonator.
6, the tensile properties: continued 1min, closures and foot line should not occur visual evidence of damage or move under static tensile force 78.4N, the electrical properties should meet the requirements.
7, water resistance: immerse pressure (0.05 ± 0.02) MPa water, holding 4h, remove the ignition was made after tests should explode completely.
8, heat resistance: 85 ℃ products remain in the environment should not explode in 4h, and shall be able to detonate; 4h should be able to maintain normal detonate in the environment of -40 ℃.
