摘要: Four fire extinguishing agents has been investigated, bromotrifluoromethane, Halon 1301, pentafluoroethane, HFC 125, heptafluoropropane, 227ea and dodecafluoro-2- methylpentane-3-one, C6F-ketone. The inerting concentrations were determined in a cubic pressure vessel with volume of 8 litres. A cup burner was used to find the flameextinguishing for agents. Thermal breakdown also studied this purpose agent introduced into flame propane tubular burner. produced combustion products analysed both conventional IR-techniques FTIR. It found that HF COF2 from all Models theories on mechanisms processes are presented. (Less)
