Product Description

Overview:It is used for deep hole field mixing and other electronic detonators with high requirements of water resistance, wear resistance, tensile resistance and vibration resistance.

Technical parameters:

Product Name Shell Material detonator length Foot line specifications Foot line length Ground connection
reinforced electronic detonator Blue steel shell 80mm/85mm Outer diameter Ф 3mm, inner core Ф 0.59mm 3m (can be adjusted according to user requirements) Ф 0.6mm core copper wire

Main performance indicators:
● Low temperature resistance of the foot wire: the foot wire of the electronic detonator shall be wound at -40 ℃ for 4h, and the sample shall be free of leakage core.
● Tensile performance of foot wire: the foot wire of electronic detonator shall last for 5min under the condition of applied static pressure ≥ 294N, and the core wire and insulating layer shall be free of fracture and damage.
● Seismic performance: seismic performance: placed in a vibration testing machine with cam rotation speed of (60±1)r/min and falling height of (150±2)min, vibrate continuously for 10min without explosion, loose structure or damage, and the electronic detonator shall be able to detonate normally.
● Water resistance: Immerse the electronic detonator in water with a pressure of (0.5±0.02)MPa at room temperature for 72h; after being taken out, the electronic detonator shall be able to detach normally.
● Tensile performance: apply a static tensile force of 19.6N to the sealing plug for 1min. The sealing plug and foot line shall not be visually damaged and moved, and the detonator shall be able to normally explode.
● Temperature resistance: it should be able to detonate normally after being kept at 85 ℃ and -40 ℃ for 4h; No explosion will occur after being kept at 100 ℃ for 4h.
● Extension accuracy: the extension time range is 0ms ~ 8000ms. When the extension time is not more than 150ms, the error is not more than 1.5ms. When the extension time is more than 150ms, the relative error is not more than 1%.
● Electrostatic sensitivity: under the conditions of capacitance 500pF, series resistance 5000Ω and charging voltage 25kV or under the conditions of capacitance 2000pF, series resistance 0Ω and charging voltage 8kV, the electronic detonator shall not explode when discharging the detonator foot-foot wire and foot wire-shell;
● Radio frequency sensitivity: a radio frequency source with a power of 10W is used to inject radio frequency energy into the detonator. Under the two modes of foot line-foot line and foot line-tube shell, the detonator will not explode.
● Anti-voltage performance: apply 48v DC voltage or 220v/50Hz AC voltage to the electronic detonator for 10s, and the detonator shall not explode.
● Initiation ability: It can blow through 5mm thick lead plate, and the diameter of perforation should not be less than the outer diameter of electronic detonator.

Method of use:
● Equipment registration: log in to the "Civil Explosion Information System Network Service Platform" for registration, set explosion ban rules, and bind blasting projects.
● Get the ciphertext file:
(1) Offline mode: log in to the civil explosion system → obtain the ciphertext file or generate the ciphertext two-dimensional code → import the ciphertext file into the initiator or scan the ciphertext two-dimensional code to obtain the ciphertext. This method is mainly applicable to underground mines and blasting areas without mobile signal coverage of the blasting project, the ciphertext file is valid for 3 days.
(2) Online mode: the initiator is connected to the mobile network to enter the product in the initiator → obtain the ciphertext file online. This method is mainly applicable to open-pit mines and blasting projects with mobile signal coverage in the blasting area, and the validity period of the ciphertext document is 3 days.
● Single-hair test: Before use, please carry out single-hair test on the product under safety protection conditions to ensure that the product is normal.
● Detonator hole entry, charging and filling (when used in tunnel and underground mining face, it is recommended to enter the detonator first and set up a segmented delay time before detonator hole entry, charging and filling)
● detonator entry and delay setting: enter the product according to the delay scheme scan code → view the delay scheme.
● Connection and networking: lay blasting busbar → correctly clamp each generator on the busbar.
● Network detection: connect the blasting bus with the initiator → conduct network detection outside the safe distance
● timing initiation: alert → click timing initiation → high voltage charging → initiation.
● Post-explosion inspection: after confirming the safety of the explosion zone according to the blasting regulations, the post-explosion inspection shall be carried out on the explosion zone.

● 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.
● It is forbidden to use the detonator as a drilling tool.
● This product shall not coexist with explosives and detonating cord.
