MFB series mine detonator

MFB series of mine having a mine suitable initiator explosive mixture of methane, coal dust and the like, operating at ambient temperature -10--35 ° relative humidity of ninety-eight percent, for initiation of electric detonators It is also suitable for use in other mining mining, mountain, stone and clearing obstacles, etc., as an energy device for detonating electric detonators.

High-energy initiators are dual-purpose detonators designed for detonating needles to detonate plastic detonators. It adopts a strong phenolic acid plastic casing and its excitation boost circuit, which has the advantages of high ignition rate, fast charging speed and convenient installation of the detonating needle. The detonating needle utilizes the concept and test principle of the axial static spark sensitivity of the plastic detonating tube. With the standard electrostatic sensitivity tester and a certain structure of the detonating needle, an experimental device can be established for the detonating tube sensitivity test, using lifting The method measures the electrostatic energy required for detonating the detonating tube and uses it to characterize the sensitivity of the detonating tube. The sensitivity test was carried out with three kinds of detonating tubes. Under the experimental conditions, the sensitivity values ​​E0.50 were 0.43, 1.08, >1.94J, respectively. The experimental results show that the energy standard can scientifically and accurately represent the detonation sensitivity of the detonation tube produced by the factory, and the measurement result is reliable. The temperature of the detonation needle detonation output flame is determined by the improved sodium line reversal method. 250k or so is suitable for 2---300 meters long-distance remote control detonating detonator.

XS Hub Centric Rings, designed to fill in the gap between the hub of the car and the center bore of the wheel for averting vibration. There ar two kinds of material used, one is PE, another is T6-6061 aluminum.
