Ma HFO

Ma Hydrofluoroolefins (HFOs) ndi mankhwala osakhuta omwe ali ndi haidrojeni, fluorine ndi kaboni. Mosiyana ndi ma hydrofluorocarbons achikhalidwe (HFCs) ndi ma chlorofluorocarbons (CFCs), omwe ndi odzaza, ma HFOs ndi ma olefins, omwe amadziwikanso kuti alkenes. Ma HFOs akupangidwa ngati ma refrigerant a "m'badwo wachinayi" omwe ali ndi mphamvu yochepa kwambiri yotenthetsera padziko lonse lapansi yomwe ndi 0.1% ya ma HFCs. Zogulitsa za HFO zimakhala ndi nthawi yochepa yopuma mumlengalenga ndipo zimagawidwa m'magulu monga opanda ODP (Ozone Depletion Potential) ndi otsika GWP (Global Warming Potential), zomwe zimapereka njira ina yabwino kwambiri yosamalira chilengedwe kuposa ma CFCs, HCFCs ndi ma HFCs.
Thovu la polyurethane lopangidwa pogwiritsa ntchito ma HFO ngati chofukizira limagwiritsidwa ntchito kwambiri m'magawo a magalimoto ndi zomangamanga monga thovu losinthasintha komanso lolimba lomwe likuyendetsa kukula kwa msika wa HFO.
