Study on mechanical behavior of NaHCO3 extinguishing powder

摘要：

　　In order to promote NaHCO3 extinguishing powder farther application in explosion extinguishing fire field,Mechanical behavior of the loose and pre-compression NaHCO3 powder was studied by MTS and SHPB experimental apparatus.The results showed that the loose and pre-compression powder were viscous material.With pre-pressure increased,the density and yield strength of pre-compression power increased,but the porosity decreased.With strain rate increased,the yield strength of pre-compression increased.
