***5  BEST-SELLER DETONATION CORD FOR ROCK BLASTING 
1.OUTLINE :
A detonation cord for rock is ±1g/m; 4#:7~8g/m. The fuse is used mainly in the blasting of decorative or building rocks,  and also in controlled blasting, smooth-surface blasting, and presplitting blasting.
2.APPLICATION :
To be used in rock blasting operations and in a explosive network connected to the ground  surface. 
3.PERFORMANCE:
Detonation velocity: 6,**0~7,**0m/s. one specially designed for rock blasting operations.  It is made of a purpose made explosive wrapped a special covering. It has the detonation  velocity and detonation pressure as  required by rock blasting operations, as well as the  detonation sensitivity and tensile strength of a common detonation fuse. Its principal strengths include the high detonation  velocity, evenly distributed charge, and ability of making smooth sections of the blasted  rock. According to different rock types, the fuse can have four different charge amounts: 1#:*8g/m±1g/m; 2#:*9g/m±1g/m;3#:*1g/m
Propagation of explosion: the fuse itself is fastened, spliced and connected with double  bowlines; and can be fully detonated using a No.8 blasting cap.
Detonating performance: a 1.5m fuse can reliably detonated a **0g TNT charge.
Water resistance: the fuse, if wrapped by cotton thread, can keep its detonating performance 
unchanged after being placed one meter deep in calm water with a water temperature  between *0℃ and *5℃ for four consecutive hours; the fuse, if wrapped by a plastic  covering, can  keep it unchanged after being placed five meters deep in calm water with a water  temperature between *0℃ and *5℃ for five consecutive hours.
Heat resistance: the detonating performance keeps unchanged after being placed under *0℃±2℃ for six consecutive hours.
Freezing resistance: the detonating performance keeps unchanged after being placed under **0℃±2℃ for two consecutive hours.
Tensile property: the detonating performance keeps unchanged after the fuse is under **0N  static tension.

4.PACKING:
To be wrapped by plastic bags inside and placed in cartons outside.
1# and 2#: four rolls of or**0 meters of the fuse(**0m each roll) to be in one carton;
