What is gas expansion
The carbon dioxide would be changed from the liquid state to gas state immediately after it is being heated, then the gas would form very big pressure inside the tube which would lead to the volume expansion and produce a very big expansive force .
The popularization and application of the Carbon dioxide
Carbon dioxide is one of the normal chemical compound in the air,when the carbon combined with the oxygen then the carbon dioxide produced. The carbon dioxide can be widely used in the fire extinguisher,gas -shielded welding machine and other products well.
Huge Volume Changes
After transient heating ,the carbon dioxide would be changed from the liquid state to the steam state, When the state changed, the volume would be 600times bigger than before.
Gas expansion to fracturing—blasting
After transient heating,the carbon dioxide would be changed from the liquid state to the gas state, When state changed, a big pressure would be of formed then the rock would be cracked after the blasting disc being broken. Indeed, the gas volume is only the power source to produce the gas pressure, the gas pressure is the true reason to lead the rock cracking not like some suppliers said the bigger the gas volume is, the better the rock cracking effective is.
It can be used in combination, that is, a single hole can be used for 5 kg, 3 kg, 2 kg and other disposable plastic paper tubes of different specifications.

Gas expansion fracturing
CO2, gas expansion fracturing is a result of physical volume change, it has not shock wave, vibration wave, blasting wave, etc. That means gas expansion forms from combined action of gas volume and pressure, instead of explosive.
No impact wave
No vibration Wave
No blasting wave
