Tetrafluoroethane R134A (C2H2F4)

Halbeegyada Farsamada:

R134a (1,1,1,2-tetrafluoroethane) waa midka ugu badan ee la isticmaalo dhexdhexaad iyo heerkulka hooseeya qaboojiyaha bay'ada u fiican. R-134a waa qaboojiye aan ku jirin atamooyin koloriin ah, oo aan waxyeello u geysan lakabka ozone, oo leh waxqabad badbaado oo wanaagsan (aan guban karin, aan qarxin, aan sun ahayn, aan xanaaqin, aan xoqin), awoodeeda qaboojinta iyo wax-ku-oolnimada Waxay aad ugu dhowdahay R-12 (dichlorodifluoromethane, Freon), marka waxaa loo arkaa inay tahay qaboojiye kale oo muddo dheer aad u fiican. R-134a ayaa hadda caalamku u aqoonsan yahay inuu yahay beddelka deegaanka ugu fiican ee R-12. Ma burburiso lakabka ozone. Waa qaboojiye bay'ada u fiican oo aqoonsaday oo ku taliyay waddamada adduunka intooda badan. Sidoo kale waa qaboojiyaha caadiga ah ee bay'ada u fiican. Waxaa si weyn loogu adeegsadaa rakibidda hore iyo dayactirka qalabka cusub ee qaboojiyaha iyo qaboojiyaha. R134a waxay leedahay sumoobo aad u hooseysa, ma aha mid guban karta hawada, waxayna leedahay qaybta badbaadada A1, oo ah qaboojiye aad u ammaan badan. R134a waxaa inta badan loo adeegsadaa beero badan, oo ay ku jiraan: qaboojiyeyaasha, qaboojiyaha, qaybiyaha biyaha, qaboojiyeyaasha baabuurta, qaboojiyeyaasha dhexe, qashin -qubka, keydinta qabow, qaboojiyaha ganacsiga, mashiinnada biyaha barafka, mashiinnada jalaatada, qaybaha qaboojiyaha qaboojiyaha iyo qalabka kale ee qaboojiyaha. Aerosol propellant, aerosol medical, propellant insecticide, polymer (caag) wakiilka xumbada jirka, iyo gaaska gaashaamida alloy magnesium, iwm warshadaha, waxaana loo isticmaali karaa daawooyinka, sunta cayayaanka, qurxinta, iyo warshadaha nadiifinta. Degganaanshaha kiimikada ee R134a aad bay u wanaagsan tahay. Si kastaba ha ahaatee, sababta oo ah dareeraheeda biyaha ayaa ka sarreeya kan R22, uma fiicna nidaamka qaboojiyaha. Xitaa haddii ay jiraan waxoogaa biyo ah, waxay soo saari doontaa aashito, kaarboon laba ogsaydh ama kaarboon moono -ogsaaydh iyadoo la adeegsanayo saliidda saliidda. Nabaad -guurka ama “dahaadhka naxaasta” ayaa la soo saaraa, sidaa darteed R134a waxay u baahan tahay qalajin sare iyo nadiifinta nidaamka. R134a ma laha falcelin kiimikaad oo leh bir, bir, naxaas, aluminium iyo biro kale, waxayna saamayn yar ku leedahay zinc.

Codsiga:

Ef Qaboojiyaha:

Tetrafluoroethane waa beddelka ugu weyn ee CFC-r12, waxaa si aad ah loogu isticmaalaa aagga qaboojiyaha sida qaboojiyaha, qaboojiyaha, qaybiyaha biyaha, hawo-qaboojiyaha baabuurta, qaboojiyaha dhexe, mashiinka jalaatada, qaybta qaboojiyaha qaboojiyaha iwm.

Isticmaal kale:

Waxaa kaloo lagu dabaqaa aerosol propellant, aerosols caafimaad iyo aerosol cayayaanka; loo isticmaalo sidii polymer (caag) wakiilka xumbo jirka iyo gaaska difaaca alloy magnesium.
