COMMON DETONATION CORD FOR LARGE DEMOLITION ENGINEER
1. OUTLINE OF COMMON DETONATION CORD FOR LARGE DEMOLITION : The common detonation cord is classified into cotton thread detonation cord and plastic detonation cord. The cotton thread detonation cord is made of high explosive as its core, cotton thread and paper as its wrapper, and asphalt as its moisture-proof layer. The plastic detonation cord is made of high explosive as its core, fiber as its wrapper. And plastic as its moisture-proof layer. Its outer diameter is not more than 6.0mm. It possesses the advantages of high detonating velocity, complete detonation and good water-resistant property, its quality reaches the advanced level of the world. It won a prize of High Quality Product of Ministry and Yunnan province separately. It is used in many key engineering of our country, such as Sanxia power station. Now it is a famous product in Yunnan province. Its technical indexes is accord with GB********9. 2.PERFORMANCEOF COMMON DETONATION CORD FOR LARGE DEMOLITION : Velocity of detonation: not less than ***0m/s. Detonating sensitivity: it can be completely detonated and when connected by the specified methods. Moisture-proof capacity: The cotton thread detonating cord can be completely detonated after 4 keeping hours in water of 1m deep at the temperature of *0~*5℃ when connected by the specified methods. The plastic detonating cord can be completely detonated after 5 keeping hours in water at the temperature of *0~*5℃ and at the pressure of *0kPa when connected by the specified methods. Detonating capacity: The detonating cord of 1.5m long can completely detonate a TNT block of **0g(press charge). Pulling-resistant capacity: It can be completely detonated after bearing a static pulling force of **0N. 3.APPLICATION OF COMMON DETONATION CORD FOR LARGE DEMOLITION :
When connected into a cord net in the large demolition engineering and ignited by a detonator, it can detonate explosive bag groups.
It is suitable for the demolitions in the open air and without explosion gas, coal dust or marsh gas.
4.PACKING OF COMMON DETONATION CORD FOR LARGE DEMOLITION : Box packing: Inside: plastic bag; Outside: paper box or wooden box. Dimension of paper box: **6 x **6 x **6mm. **0m each box (*0 rolls each box. *0m each roll or 2 rolls each box, **0m each roll), *6kg each box(Gr. Wt.).
