Tetrafluoroethane R134A (C2H2F4)

Nā Kauoha Kōmike:

ʻO R134a (1,1,1,2-tetrafluoroethane) ka mea hoʻohana ākea a me ka haʻahaʻa haʻahaʻa e hoʻomaʻamaʻa ai i ka nohona. ʻO R-134a he pahu anuanu ʻaʻole ia i loko o nā chlorine atoms, ʻaʻole ia e hōʻino i ka ozone layer, a he hana palekana maikaʻi (non-flammable, non-explosive, non-toxic, non-irritating, non-corrosive), kona hiki anuanu a me ka hoʻokō ʻana Ua kokoke loa ia i R-12 (dichlorodifluoromethane, Freon), no laila ua manaʻo ʻia ia me kahi maikaʻi loa o ka wā ʻoi loa o ka pahu hau. ʻIke ʻia ʻo R-134a i kēia manawa ma ke ʻano he ʻoliʻoli kūlohelohe maikaʻi loa no R-12. ʻAʻole ia e luku i ka ozone āpau. He ipu anuanu maikaʻi ia e ʻike ʻia a paipai ʻia e ka hapa nui o nā ʻāina i ka honua. ʻO ia nō hoʻi ka coolant friendly environmentally mainstream o kēia manawa. Hoʻohana ākea ia i ka hoʻokumu mua a me ka mālama ʻana i nā pono hoʻoilo hou a me nā pono hoʻohe ea. He haʻahaʻa haʻahaʻa ʻo R134a, ʻaʻohe lapalapa i ka lewa, a he maʻaʻano palekana o A1, kahi mea palekana maikaʻi loa. Hoʻohana nui ʻia ʻo R134a i nā kahua he nui, e like me: nā pahu hau, nā pahu hau, nā mea hāʻawi wai, nā ʻenekini kaʻa kaʻa, nā ea lewa kikowaena, nā mea hoʻoheʻe anuanu, nā waihona anuanu, nā pahu hau kalepa, nā mīkini wai ʻaihue, nā mīkini wai kalima, nā ʻenekini condensing coolation a me nā pono hana hoʻohuihui ʻē aʻe. Aerosol propellant, medical aerosol, insecticide propellant, polymer (plastic) physical foaming agent, a me ka magnesium alloy pale i ke kinoea, a pela aku R-134a hiki ke hoʻohana ākea e like me kahi pahu hau i nā kaʻa hoʻohanohano kaʻa, nā pahu hau, nā ea ea kikowaena, ke anuanu pāʻoihana a me nā mea ʻē aʻe. nā ʻoihana, a hiki ke hoʻohana ʻia i ka lāʻau, nā pesticides, cosmetics, a me nā ʻoihana hoʻomaʻemaʻe. Maikaʻi loa ke kūpaʻa kemika o R134a. Eia naʻe, no ka mea ʻoi aku ka kiʻekiʻe o ka solubility o kona wai ma mua o R22, ʻaʻole maikaʻi ia no ka ʻōnaehana hōʻolu. ʻOiai inā he wahi liʻiliʻi o ka wai, e hoʻopuka ia i ka acid, carbon dioxide a i ʻole carbon monoxide ma lalo o ka hana o ka aila lubricating. Hoʻopuka ʻia ka popopo a i ʻole "plating keleawe", no laila pono ʻo R134a i kahi maloʻo kiʻekiʻe a hoʻomaʻemaʻe o ka ʻōnaehana. ʻAʻohe hopena kemika o R134a me ka hao, hao, keleawe, aluminika a me nā metala ʻē aʻe, a he hopena iki wale nō ka zinc.

RRefrigerant:

ʻO Tetrafluoroethane kahi koho nui no CFC-r12, hoʻohana ākea ʻia ia ma ka hapanui o ka pahu hau e like me ka pahu hau, pahu hau, mīkini wai, kaʻa ea, kaʻa hoʻoneʻe kikowaena, mīkini ʻaikalima, mīkini condensing cooler a pēlā aku.

Ther ʻOihana ʻē aʻe:

Hoʻohana ʻia ia i ka propellant aerosol, aerosol lapaʻau a me aerosol insecticide; hoʻohana 'ia e like me polymer (ea) kino foaming konohiki a me ka makanekiuma oka a pale pale kinoea.
