Study on Explosion Suppression Performance of Spherical Nonmetallic Materials

Taking horizontal shock tube as the main equipment in this paper, using chemical ignition and high voltage ignition as the ignition source to evaluate the flame wave propagation characteristics of spherical nonmetallic explosion-suppression materials and aluminium alloy explosion-suppression materials when the horizontal shock tube was filled with No. 93 gasoline and liquefied petroleum gas vapors. The trend of peak overpressure and the flame propagation speed was tested, and the mechanism of flame and overpressure propagation was analyzed in the experiment. The results show that the spherical nonmetallic materials are better than aluminium alloy explosion-suppression materials for peak overpressure and flame wave propagation velocity suppression.
