Tetrafluoroethane R134A (C2H2F4)

Tapulaʻa faʻatekonolosi:

R134a (1,1,1,2-tetrafluoroethane) o le sili ona lautele faʻaaogaina auala ma maualalo vevela faʻamamaina siosiomaga pusaaisa. R-134a o se pusa 'aisa e le o aofia ai ni chlorine atoms, e le faʻaleagaina le osone layer, ma e lelei lona saogalemu faʻagaioiga (e le mumu, e le pa, e le oona, e le faʻaitaita, e le o pala), o lona malosiaga malulu ma le lelei E latalata tele i le R-12 (dichlorodifluoromethane, Freon), o lea e manatu ai o se sili ona umi-isi suʻega pusaaisa. R-134a o loʻo aloaia faʻavaomalo faʻavaomalo o se sili ona lelei siʻosiʻomaga sui mo R-12. E le faʻaleagaina uma le vaega ole osone. O se siosiomaga faauo faʻamamaisa faʻaalia ma fautuaina e le tele o atunuʻu i le lalolagi. O le taimi nei foi faʻaauau faʻatonutonu siʻosiʻomaga faʻamafanafana. E lautele faʻaaogaina i le faʻapipiʻiina muamua ma le tausiga o fou pusaaisa ma ea-malulu masini. O le R134a e maualalo lona oona, e le mafai ona mu i le ea, ma e iai le vaega o le saogalemu o le A1, o se pusaaisa saogalemu tele lea. O le R134a e tele na faʻaaogaina i le tele o matata, e aofia ai: pusaaisa, pusaaisa, masini faʻasoa vai, taʻavale faʻafoe, taʻavale faʻatonu, faʻamago malulu, faʻamalama malulu, masini vai aisa, masini aisa kulimi, vaega faʻapipiʻi aisa malulu ma isi mea faʻavela. Aerosol propellant, medical aerosol, insecticide propellant, polymer (palasitika) foaming agents soʻofaʻatasi, ma magnesium uʻamea uʻamea puipui puipuia, ma isi R-134a mafai ona lautele faʻaaogaina o se pusaaisa i taʻavale ea malulu, pusaaisa, faʻatonu ea ea, faʻamalama faʻamalama faʻamalama ma isi alamanuia, ma e mafai ona faʻaaogaina i vailaʻau, vailaʻau, vailaʻau faʻalelei, ma faʻamama falegaosimea. O le vailaʻau tumau o R134a e lelei tele. Peitai, talu ai o lona vai solubility e maualuga atu nai lo o R22, e le lelei mo le pusaaisa faiga. Tusa lava pe iai se vai laʻititi, e maua ai le acid, carbon dioxide poʻo le carbon monoxide i lalo ole gaioiga o le suauʻu gaʻo. Paʻu poʻo "apamemea plating" e gaosia, o lea R134a manaʻomia maualuga faamagoina ma le faʻamamaina o le faiga. R134a e leai se vailaʻau e faʻaalia i uʻamea, uʻamea, 'apamemea, alumini ma isi metala, ma e na o sina aʻafiaga i le metala paʻepaʻe.
