How It Works

1

Rapid Phase Change

Liquid CO₂ is heated rapidly within 20-40 milliseconds by an electric activator. The liquid undergoes phase transition to gaseous or supercritical state, causing instantaneous volume expansion of over 600 times and generating extreme pressure (200-300 MPa).

2

Pressure Relief & Jet Formation

When pressure exceeds the rupture threshold (60-270 MPa adjustable), the pressure-relief disc bursts, releasing high-pressure CO₂ gas as a high-speed jet through the nozzle, reaching hundreds of meters per second.

3

Two-Stage Fracturing

Dynamic Stress Wave: The jet creates shock waves, initiating primary cracks. Gas Wedging: High-pressure gas infiltrates cracks, driving propagation until rock fragments completely.
