Hypothesis

The study investigates the explosion pressure of industrial titanium powder and the effectiveness of different explosion suppressants.

Conclusion

The optimal mass concentration for titanium powder explosion is 350 g/m³, and the best suppression agent is NaHCO3.

Supporting Evidence

  • The maximum pressure of titanium powder explosion is 0.48 MPa at an optimal concentration of 350 g/m³.
  • The optimal ignition delay time for maximum explosion pressure is 50 ms.
  • NaHCO3 is the most effective suppressant, followed by K2CO3 and SiO2.

Takeaway

This study looks at how much pressure titanium powder can create when it explodes and how different materials can help stop that explosion.

Methodology

The study involved experiments to measure explosion pressure under varying conditions of titanium powder concentration and ignition delay time, as well as the effects of different suppressants.

Limitations

The study primarily focuses on specific suppressants and may not cover all possible explosion suppression methods.
