ITetrafluoroethane R134A (C2H2F4)

Iparameters technical

I-R134a (1,1,1,2-tetrafluoroethane) yeyona ndawo isetyenziswa kakhulu kubushushu obuphakathi nobuphantsi obunobungqongileyo. I-R-134a sisiqandisi esingenazo iiathom zeklorine, esingonakalisi umaleko weozone, kwaye sisebenza kakuhle kukhuseleko (esingenakutsha, esingadubuliyo, esingesityhefu, esingacaphukisiyo, esingonakalisiyo), amandla aso okupholisa kunye nokusebenza kufutshane kakhulu ne-R-12 (dichlorodifluoromethane, Freon), ke ithathwa njengeyona ndlela ibalaseleyo yexesha elide. I-R-134a okwangoku yamkelwe kwilizwe liphela njengeyona ndawo ibambekayo enokusingqongileyo eyiR-12. Ayilonakalisi kwaphela i-ozone layer. Ifriji enobungozi kwindalo esingqongileyo eyaziwayo kwaye yacetyiswa ngamazwe amaninzi ehlabathini. Ikwayindawo eqhelekileyo enobuhlobo kwindalo. Isetyenziswa ngokubanzi kufakelo lokuqala kunye nokugcinwa kwefriji entsha kunye nezixhobo zokumisa umoya. I-R134a inetyhefu esezantsi kakhulu, ayinakho ukutsha emoyeni, kwaye inecandelo lokhuseleko le-A1, nefriji ekhuselekileyo. I-R134a isetyenziswa ubukhulu becala kumacandelo amaninzi, kubandakanya: iifriji, iifriji, izixhobo zokuhambisa amanzi, izixhobo zokupholisa izithuthi, izipholisi zomoya, izixhobo zokuphelisa umoya, indawo yokugcina ebandayo, ifriji yorhwebo, oomatshini bamanzi e-ice, oomatshini bokwenza i-ice cream, iiyunithi zokujiya kwefriji kunye nezinye izixhobo zefriji. I-Aerosol propellant, i-aerosol yonyango, i-propellant ye-insecticide, i-polymer (iplastiki) i-arhente yokugubha, kunye ne-magnesium alloy yokukhusela igesi, njl. amashishini, kwaye ingasetyenziselwa amayeza, i-pesticides, izimonyo, kunye nokucoca amashishini. Uzinzo lweekhemikhali lwe-R134a lulunge kakhulu. Nangona kunjalo, ngenxa yokuba ukunyibilika kwamanzi kuphezulu kune-R22, ayiyilunganga inkqubo yefriji. Nokuba kukho isixa esincinci samanzi, iya kuvelisa iasidi, icarbon dioxide okanye icarbon monoxide phantsi kwentshukumo yeoyile yokuthambisa. Umhlwa okanye "isingxobo sobhedu" senziwe, ke i-R134a ifuna ukomiswa okuphezulu kunye nokucocwa kwenkqubo. I-R134a ayinasabela yekhemikhali yentsimbi, intsimbi, ubhedu, i-aluminium kunye nezinye izinyithi, kwaye inefuthe elincinci kwi-zinc.

Isicelo:

Ifriji:

I-Tetrafluoroethane yeyona ndlela iphambili kwi-CFC-r12, isetyenziswa kakhulu kwindawo ebanzi yesifriji njengefriji, ifriji, isixhobo sokuhambisa amanzi, isixhobo sokupholisa umoya, indawo yokupholisa umoya, umatshini we-ayisi khrim, iyunithi yokujija ifriji njl.

Olunye usetyenziso:

Ikwasetyenziswa nakwi-erosol propellant, i-aerosol yonyango kunye ne-aerosol yokubulala izinambuzane; Isetyenziswa njengepolymer (iplastiki) iarhente egwebu ngokwasemzimbeni kunye nemagniziyam alloy igesi yokukhusela.

Iphakheji yesiqhelo:
