The Shock Tube Delay Detonator

The Shock Tube Delay Detonator (fire cracker) is for blasting works in coal mine or in the open pit digging tunnels.

Uses: The  Shock Tube Delay Detonator (fire cracker) is suitable for the blasting works in coal mine or in the open pit digging tunnels where present no fire damp or coal dust. This kind of detonator cannot be affected by static and stray electrical current, high frequency radio transmissions when used.

Performances:

It resists the test of78.4N static stretch for1min, all parts connected are not disjointed.

Base charge (RDX) is 0.8g, it has highly initiating power. It can initiate all dynamites and cap sensitive explosive.

Note: should take care in handing, prohibit to be impacted violently, away from fire source and high temperature objects and should not be exposed to sunshine and rain in order to prevent from exploding and deteriorating. The conjunction of connector and detonating cord should follow the strict guard when used.

Storage: it should be stored in a ventilating and dry storehouse under the original package condition.

Shelf-life: 2years

Packing: Two ling paperboards in one little carton, two little cartons in one big carton (or on requirement of user).
