Study On Chain Scission Of Gas Explosion Reaction In Foam Ceramics

In order to reveal the mechanism of gas explosion suppressed by foam ceramics, ultra-depth three-dimensional microscope VHX-600 is applied to measure and analyze the micro-structure of foam ceramics. Then combining with the theory of chain reaction and wall effect, gas explosion reaction and foam ceramics wall effect are quantified. The results show the special three-dimensional mesh structure of ceramic foam is beneficial to destroy free radicals in gas explosion reaction, chain scission of the reaction can be terminated, gas explosion propagation can be suppressed.
