摘要：
To obtain a good explosive suppressant, KH2PO4/montmorillonite composite powder was prepared by the solvent-antisolvent method by using montmorillonite as the carrier and KH2PO4 as the supported particles. Flame propagation inhibition and explosion inhibition of aluminum-silicon alloy dust by the KH2PO4/montmorillonite composite powder were investigated in a vertical quartz glass combustion tube and 20-L spherical explosive tank, respectively. The results showed that the flame propagation of aluminum-silicon alloy dust was basically suppressed as the inerting ratio of KH2PO4/montmorillonite composite powder was 1.2, and the explosion of aluminum-silicon alloy dust was basically inhibited as the inerting ratio of KH2PO4/montmorillonite composite powder was 1.8. The flame and explosion inhibition mechanism of KH2PO4/montmorillonite composite powder on aluminum-silicon alloy dust was further analyzed in this paper.
