摘要:
A process for extinguishing, preventing and controlling fires using a composition containing at least one fluoro-substituted propane selected from the group of CF3-CHF-CF3, CF3-CF2-CHF2, CF3-CFH-CF2H, CF3-CH2-CF3, CF3-CF2-CH2F, CHF2-CF2-CHF2, CF3-CF2-CHCl2, CHFCl-CF2-CClF2, CHF2-CCl2-CF3, CF3-CHCl-CClF2, CHF2-CF2-CHClF, CF3-CF2-CH2Cl, CClF2-CF2-CH2F, CF3-CH2-CClF2, CHClF-CF2-CF3, CHF2-CF2-CF2Cl, CF3-CHCl-CF3, CF3-CHF-CF2Cl, and CHF2-CFCl-CF3 is disclosed. The fluoropropanes can be used in open or enclosed areas with little or no effect on the ozone in the stratosphere and with little effect on the global warming process.
摘要:
A fire extinguishing composition consisting of (a) one or more fire extinguishing compounds selected from bromodifluoromethane, 1-bromo-1,2,2,2-tetrafluoroethane, 1-chloro-1,2,2,2-tetrafluoroethane and 1,1-dichloro-2,2,2-trifluoroethane and optionally one or more of (b) a completely halogenated fluorobromoalkane(s) and/or fluorobromochloroalkane(s), (c) a coadjuvant agent(s) having a boiling point below 0°C and (d) a gaseous propellant(s).
摘要:
A fire extinguishing composition which comprises bromofluorohydrocarbon and/or bromochlorofluorohydrocarbon and a fluorine-containing high molecular compound.
摘要:
Fire-extinguishing compositions of low ozone depletion potential comprise dry particles of fire-extinguishing agents dispersed in a gel of liquified volatile perfluorocarbons, chlorofluorocarbons or hydrofluorocarbons. The dry particles are compatibilized with the carrier gel by the presence of a surfactant system composed of a non-ionic surfactant, a film forming fluorocarbon surfactant and a phosphorus containing antiflocculant.

摘要:
A process for extinguishing, preventing and controlling fires using a composition containing at least one fluoro-substituted ethane selected from the group of CF3-CHF2, CHF2-CHF2, CF3-CH2F, CF3-CHFCl, CF2Cl-CHF2, CF3-CHCl2, CF2Cl-CHFCl, CFCl2-CHF2, and CHFCl-CHFCl is disclosed. The ethane can be used in open or enclosed areas with little or no effect on the ozone in the stratosphere and with little effect on the global warming process.
摘要:
