Working principle:

Carbon Dioxide (CO2), it can be liquefied under high-pressure situation. Filling the liquefied CO2 into a special cylinder (blasting cartridge ) by high-pressure pump, then installs safety diaphragm, bursting disc, heat conduction rod, gasket ring, and tighten the end cap, that finish the preparation works of the blasting.

Take the blasting cartridge, initiator, power cables to the working site. Put the blasting cartridge into pre-drilled holes, connect power supply to the initiator, when the current go through heat conduction rod, it causes high-temperature to break the safety diaphragm down, liquid CO2 will gasify instantly and expand suddenly, which causes high impact force to break through the relief valve and generate geometric-level power to demolish the blasting objects.

The whole procedure is only 0.4 millisecond, it just works under usual circumstance, does not mix together with other liquid or gas, no harmful gas, no electric arc or spark, does not limited by high-temperature, humidity, cold, etc. Meanwhile, It can dilute the gas inside pit, no shock, no powdery. CO2 is a kind of inert gas, but not flammable and explosive. The blasting procedure is just a physical works instead of chemical reaction.


Applications:
1.    Mining: surface mine development, digging in pit, etc.
2.    SOS: wrecker, quake lake, clear landslip, flood discharge, reinforce dam, etc.
3.    Metro, tunneling and municipal engineering: hard rock demolishing, directional blasting of concrete building, digging and channeling, etc.
4.    Geological survey: drilling and sampling, quarrying, stone-slab cutting, etc.
5.    Loosening works: ice breaking, snow-peak blasting , powdery or nubbly loosen, etc.
6.    Underwater project: submarine channel dikage,  submarine mine blasting, etc.


Advantages:
1.    Safety: safe from storage, transport, usage, recovery, etc. Control panel is away of blasting materials. The whole procedure is in short time from gas-filling to the end of blasting, gas-filling takes only 1-3 minutes, while blasting takes only 0.4 milliseconds, no failure, no need test, short safety-distance, no hidden danger, recoverable and reusable.
2.    Directional blasting, time-delay blasting: No destructive effect to the specific sites, somewhere like residential area, channel, metro, pit, etc. No destructive shock or short-wave.
3.    High yield and high efficiency during quarrying, do not effect stone’s texture structure.
4.    Labor-saving: easy to manage or operate, few operators only, no need occupational watchkeeper.
5.    No approval of approval procedure, all components are non-explosive before gas-filling. Can gather materials easily on spot/
6.    Increase blasting force easily: more expansion tubes, more powerful.
