I-Tetrafluoroethane R134A (C2H2F4)

Amapharamitha wezobuchwepheshe:

I-R134a (1,1,1,2-tetrafluoroethane) iyifriji esetshenziswa kakhulu phakathi nendawo naphansi. I-R-134a iyisiqandisi esingaqukethe ama-athomu e-chlorine, engalimazi ungqimba lwe-ozone, futhi inokusebenza okuhle kokuphepha (okungashisi, okungadubuli, okungekho ubuthi, okungacasuli, okungonakalisi), amandla ayo okupholisa nokusebenza kahle Kusondele kakhulu ku-R-12 (dichlorodifluoromethane, Freon), ngakho-ke kubhekwa njengesiqandisi esihle kakhulu sesikhathi eside. I-R-134a njengamanje yamukelwa emhlabeni jikelele njengendawo engcono kakhulu engathatha indawo ye-R-12. Akuqedi nhlobo ungqimba lwe-ozone. Kuyisiqandisi esinobungani bemvelo esaziwayo futhi esinconywe amazwe amaningi emhlabeni. Futhi iyisiqandisi samanje esivamile semvelo. Isetshenziswa kabanzi ekufakweni kokuqala nasekugcinweni kwemishini efrijini nemishini yokupholisa umoya. I-R134a inobuthi obuncane kakhulu, ayikwazi ukutsha emoyeni, futhi inesigaba sokuphepha se-A1, okuyisiqandisi esiphephe kakhulu. I-R134a isetshenziswa kakhulu emikhakheni eminingi, kufaka phakathi: iziqandisi, amafriji, izisetshenziswa zokuhambisa amanzi, ama-air conditioner ezimotweni, ama-air conditioner aphakathi nendawo, ama-dehumidifiers, indawo yokugcina ebandayo, ifriji yezentengiselwano, imishini yamanzi e-ice, imishini ye-ayisikhilimu, amayunithi okuqinisa amafriji neminye imishini yesiqandisi. I-Aerosol propellant, i-aerosol yezokwelapha, i-properant ye-insecticide, i-polymer (ipulasitiki) i-ejenti ekhihliza amagwebu, ne-magnesium alloy shielding gas, njll i-R-134a ingasetshenziswa kabanzi njengesiqandisi ezimotweni zomoya ezimotweni, amafriji, ama-air conditioner aphakathi nendawo, ifriji yezentengiso nokunye izimboni, futhi zingasetshenziswa ezimbonini zemithi, izibulala-zinambuzane, izimonyo nezimboni zokuhlanza. Ukuzinza kwamakhemikhali kuka-R134a kuhle kakhulu. Kodwa-ke, ngenxa yokuthi ukuncibilika kwawo emanzini kuphakeme kuno-R22, akululungele uhlelo lwesiqandisi. Noma ngabe mancane amanzi, izokhiqiza i-asidi, isikhutha noma isikhutha ngaphansi kwesenzo samafutha okugcoba. Kukhiqizwa i-corrosion noma "ipuleti yethusi", ngakho-ke i-R134a idinga ukomiswa nokuhlanzwa okuphezulu kohlelo. I-R134a ayinakho ukusabela kwamakhemikhali ngensimbi, insimbi, ithusi, i-aluminium nezinye izinsimbi, futhi inomthelela omncane nje ku-zinc.

Isicelo:

Isiqandisi:

I-Tetrafluoroethane iyindlela eyinhloko ye-CFC-r12, isetshenziswa kakhulu endaweni eningi yesiqandisi njengesiqandisi, ifriji, idrayivu yokuhambisa amanzi, i-air conditioner, i-air conditioning emaphakathi, umshini we-ayisikhilimu, iyunithi yokuqinisa ifriji njll.

Okunye ukusetshenziswa:

Iphinde isetshenziswe ku-aerosol propellant, i-aerosol yezokwelapha ne-aerosol yokubulala izinambuzane; isetshenziswa njenge-polymer (epulasitiki) ejenti ekhihliza amagwebu kanye negesi yokuvikela i-magnesium alloy.
