Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs HCFCs Hydrofluorocarbons (HFCs) yog tib neeg tsim cov organic tebchaw uas muaj fluorine thiab hydrogen atoms, thiab yog hom tshuaj organofluorine ntau tshaj plaws.. Feem ntau yog gases nyob rau hauv chav tsev kub thiab siab.

) thiab halons rhuav tshem lub ntiaj teb tiv thaiv txheej txheej ozone, uas tiv thaiv lub ntiaj teb los ntawm kev phom sij ultraviolet (UV-B) rays tsim los ntawm lub hnub.
Puas chlorofluorocarbons ua phem rau ozone?
Gaseous CFCs tuaj yeem tshem tawm cov txheej txheej ozonethaum lawv maj mam nce mus rau hauv stratosphere, tawg los ntawm cov hluav taws xob muaj zog ultraviolet, tso cov tshuaj chlorine, thiab tom qab ntawd cuam tshuam nrog ozone molecules.
chlorofluorocarbons cuam tshuam li cas rau txheej ozone?
Ib zaug nyob rau hauv qhov chaw, CFCs maj mam nce mus rau stratosphere, qhov chaw uas lawv tawg los ntawm ultraviolet hluav taws xob, tso cov tshuaj chlorine atoms, uas muaj peev xwm ua kom puas ozone molecules. … Thaum tshav ntuj rov los rau lub caij nplooj ntoos hlav, cov tshuaj chlorine pib rhuav tshem ozone.
Puas yog qhov ozone tshwm sim los ntawm CFC?
Ozone depletion tshwm sim thaum chlorofluorocarbons ( CFCs) thiab halons-gases yav tas los pom nyob rau hauv aerosol spray poom thiab refrigerants-tso tawm rau hauv cov huab cua (saib cov ntsiab lus hauv qab no). … CFCs thiab halons ua rau cov tshuaj tiv thaiv uas ua rau ozone molecules, txo ozone lub ultraviolet hluav taws xob-absorbing peev.
CFCs yog dab tsi thiab lawv lub luag haujlwm hauv ozone depletion yog dab tsi?
Chlorofluorocarbons (CFCs) thiab lwm yam halogenated ozone-depleting tshuaj (ODS) yog lub luag haujlwm tseem ceeb rau tib neeg tsim tshuaj ozone depletion.… Lub chlorine atoms ua lub catalyst, thiab txhua tus tuaj yeem ua rau ntau txhiab tus ozone molecules ua ntej raug tshem tawm ntawm lub stratosphere.
