LOW CHARGE
PRIMER CORD FOR LARGE AREA OF
EXPLORATION
1.OUTLINE : A low-charge
primer cord is made of PETN wrapped outside with some cotton thread and plastic material. 2.PROPERTIES:
reliable propagation of explosion
high detonation velocity
good water resistance
decent tensile Strength
small network detonating noise
high safety performance
3.APPLICATION :
1)To be used to in blasting operations in open air or under circumstances without firedamp or explosive dust;
2)used in a explosive network with multiple explosive points or with a large area of exploration;
3)and used for
detonation in cooperation with other detonating devices. 4.MODELS:
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.
5.PERFORMANCE : Detonation velocity: ≥5,**0m/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 *0kPa and a water temperature between *0℃ and *5℃ for five consecutive hours. Tensile property: the detonating performance keeps unchanged after the fuse is under **0N static tension for a minute. Lo/hi temp.resistance: the detonating performance keeps unchanged after being placed under *0℃±2℃ for six consecutive hours and **0℃±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.
6.PACKAGING : Ten rolls of or 1,**0 meters of the fuse(**0m each roll) to be wrapped by plastic film bags(five rolls in each
bag) contained in one carton.
