HFA 152a kev kho mob propellant HFA 152A Inhalant khoom propellants rau asthmatic
HFA-152a yog ib qho hydrofluoroalkane (HFA) uas feem ntau yog siv los ua cov tshuaj tua kab mob hauv cov tshuaj aerosol, xws li cov tshuaj inhalers. Nws muaj cov tshuaj formula C2H4F2 thiab qhov kub ntawm -24 degree . HFA-152a muaj qhov muaj peev xwm ua rau lub ntiaj teb qis qis (GWP) thiab ozone depletion peev (ODP), ua rau nws xaiv ib puag ncig zoo dua piv rau cov laus dua li cov chlorofluorocarbons (CFCs) thiab hydrochlorofluorocarbons (HCFCs).
