Tetrafluoroethane R134A (C2H2F4)

Luso magawo:

R134a (1,1,1,2-tetrafluoroethane) ndi firiji yosavuta kugwiritsa ntchito yapakatikati komanso yotsika kwambiri. R-134a ndi firiji yomwe ilibe maatomu a chlorine, sawononga ozoni wosanjikiza, ndipo imakhala ndi chitetezo chabwino (chosapsa, chosaphulika, chosakhala chakupha, chosakhumudwitsa, chosawononga), kuzirala kwake ndi kuyandikira Kwambiri ili pafupi kwambiri ndi R-12 (dichlorodifluoromethane, Freon), chifukwa chake imawonedwa ngati firiji yabwino kwambiri yayitali. R-134a pakadali pano amadziwika padziko lonse lapansi ngati cholowa m'malo mwa R-12. Sichiwononga mpweya wa ozoni konse. Ndi refrigerant wochezeka anazindikira ndipo tikulimbikitsidwa ndi mayiko ambiri padziko lapansi. Imeneyi ndi refrigerant yapano pano yokhazikika. Amagwiritsidwa ntchito kwambiri kukhazikitsa koyambirira ndi kukonza zida zatsopano zafiriji komanso zowongolera mpweya. R134a ili ndi poyizoni wotsika kwambiri, siyotentha mlengalenga, ndipo ili ndi gulu lotetezedwa la A1, lomwe ndi firiji yotetezeka kwambiri. R134a imagwiritsidwa ntchito kwambiri m'magawo ambiri, kuphatikiza: mafiriji, mafiriji, makina operekera madzi, makina opangira magalimoto, ma air conditioner apakatikati, okonza madzi ozizira, malo osungira ozizira, mafiriji, makina amadzi oundana, makina a ayisikilimu, mayunitsi ozizira komanso zida zina zafiriji. Mafuta opopera, opopera mankhwala, opopera tizilombo, polima (pulasitiki) wothandizila thovu, ndi mpweya wa magnesium aloyi woteteza, etc. R-134a itha kugwiritsidwa ntchito kwambiri ngati firiji m'galimoto zamagalimoto, mafiriji, ma air conditioner apakati, firiji yamalonda ndi zina mafakitale, ndipo atha kugwiritsidwa ntchito ngati mankhwala, mankhwala ophera tizilombo, zodzoladzola, komanso mafakitale oyeretsera. Kukhazikika kwamankhwala kwa R134a ndikwabwino kwambiri. Komabe, chifukwa kusungunuka kwake kwamadzi ndikokwera kuposa R22, sizabwino pamafiriji. Ngakhale madzi atakhala ochepa, amatulutsa acid, carbon dioxide kapena carbon monoxide poyikidwa mafuta. Dzimbiri kapena "zokutira zamkuwa" zimapangidwa, chifukwa chake R134a imafuna kuyanika kwambiri ndikuyeretsa makinawa. R134a ilibe mankhwala ndi chitsulo, chitsulo, mkuwa, aluminium ndi zitsulo zina, ndipo imangokhala ndi zotsatira zochepa pa zinc.

Ntchito:

EfFiriji:

Tetrafluoroethane ndi njira ina yayikulu ya CFC-r12, imagwiritsidwa ntchito kwambiri m'chigawo chachikulu cha firiji ngati firiji, firiji, choperekera madzi, makina opangira magalimoto, makina oziziritsa mpweya, makina a ayisikilimu, firiji yolowera etc.

Ntchito ina:

Amagwiritsidwanso ntchito popanga mafuta, ma aerosol azachipatala ndi mankhwala ophera tizilombo; ntchito ngati polima (pulasitiki) thupi thovu wothandizila ndi magnesium aloyi mpweya zoteteza.
