low charge detonating fuse

Descripción del producto

A low-charge detonating fuse is made of PETN wrapped outside with some cotton thread and plastic material. It has three fix models according to their different charge: 3~4g/m; 4.5~5g/m; and 5.5~7g/m. The fuse can be customized with any change between 3 and 7g/m. The fuse is characterized by its reliable propagation of explosion, high detonation velocity, good water resistance, decent tensile

Strength, small network detonating noise, and high safety performance. All in all, it is high-performance detonating device.

Detonation velocity: ≥5,000m/s

Detonating performance: the fuse can reliably detonate an explosive charge.

Propagation of explosion: the fuse itself is spliced and connected with double bowlines;

And can be fully detonated using a No.8 blasting cap.

Water resistance: the fuse can be fully detonated using a No.8 blasting cap after being placed under calm water with a water pressure of 50kPa and a water temperature between 10℃ and 25℃ for five consecutive hours.

Tensile property: the detonating performance keeps unchanged after the fuse is under 300N static tension for a minute.

Lo/hi temp.resistance: the detonating performance keeps unchanged after being placed under 50℃±2℃ for six consecutive hours and -40℃±2℃ for two consecutive hours.

Flame sensitivity: the fuse will not be detonated when the flame is jet from the fuse onto the end-face core of the fuse.

To be used to in blasting operations in open air or under circumstances without firedamp or explosive dust; used in a explosive network with multiple explosive points or with a large area of exploration; and used for detonation in cooperation with other detonating devices.

Packing : Ten rolls of or 1,000 meters of the fuse(100m each roll) to be wrapped by plastic film bags(five rolls in each bag) contained in one carton.
