This series of detonators is suitable for mines with explosive mixtures such as methane and coal dust. They are used as detonators in operating environments with temperatures ranging from -10 to 35 degrees Celsius and relative humidity of 98%. They are also suitable as energy devices for detonating electric detonators in other mining, mining, rock blasting, and obstacle removal blasting projects.
The high-energy pulse detonator produced by our factory adopts a new type of dedicated infinite energy storage capacitor, which has high initiation voltage, high energy, and more than twice the initiation capacity of other detonators. At the same time, it has a photoelectric conductivity detection function, which uses light display to detect the on-off status of the electric detonator bridge wire and the electric blasting network.
High energy detonator is a dual purpose detonator designed specifically for detonating plastic detonating tubes with a detonating needle. Adopting a sturdy phenolic plastic shell and a separate excitation boost circuit, it has the advantages of high ignition rate, fast charging speed, and convenient installation and connection of the detonating pin. This detonating needle utilizes the concept and testing principle of axial electrostatic spark sensitivity of plastic detonating tubes. A standard electrostatic sensitivity tester is used with a certain structure of detonating needles to establish an experimental device for testing the sensitivity of detonating tubes. The static electric energy required for detonating the detonating tube is measured using the lifting method and used to characterize the sensitivity of the detonating tube. Sensitivity tests were conducted on three types of detonating tubes, and the sensitivity values E0.50 under experimental conditions are 0.43, 1.08, and The experimental results show that using energy standards can scientifically and accurately represent the detonation sensitivity of the detonating tube produced by our factory, and the measurement results are reliable And the improved sodium spectral line inversion method was used to measure the temperature of the detonation output flame of the detonating needle, which is around 250k. It is suitable for remotely detonating the detonating tube detonator at a distance of 2-300 meters.
The digital high-energy detonator uses a high-definition digital tube to display clearly, which can directly display the resistance values of the electric detonator and shooting network, and can prevent misfires. This machine has the characteristics of multi-purpose, safe and reliable, sturdy and durable, simple operation, and convenient use.
