Aluminum powder explosion accidents occurred frequently,but the mechanism of aluminum powder explosion is ***,the inhibitive effect of aluminum powder explosion plays a key *** evaluate the inhibition capacity of different kinds of carbonates and phosphates:Na H2PO4,(NH4)2HPO4,NH4H2PO4,KHCO3 and Na HCO3 on aluminum deflagrations,a standard 20-L spherical chamber was used to determine the explosion severity,characterized by the maximum explosion pressure(Pmax).New parameters have been proposed:the minimum significant inert concentration(MSIC)and the minimum complete inert concentration(MCIC),which characterized the effect of *** results showed that from the minimum significant inert concentration(MSIC)and the minimum complete inert concentration(MCIC),phosphate can have a significant inhibiting effect.40%Na H2PO4 can totally inert the aluminum explosion,and 50%(NH4)2HPO4or 50%NH4H2PO4 can also suppress the *** simulation,phosphate mainly acts via a chemical inhibition pathway,which inhibits the reaction of aluminum powder and oxygen by catalyzing the recombination of H atoms and O *** performs inhibition in chemically,producing CO2,diluting the oxygen around the aluminum *** indicated that the explosion pressure of the mixture decreases as the concentration of inert dust ***,when the concentration of carbonates was low,SEEP(suppressant enhanced explosion parameter)phenomenon was *** research work has a potential industrial application in high hazard aluminum working condition,which can help decrease the explosion pressure and reduce the accident loss.
