Tetrafluoroethane R134A (C2H2F4)

Siffofin fasaha:

R134a (1,1,1,2-tetrafluoroethane) shine mafi yawan amfani da matsakaici da ƙarancin zafin jiki mai sanyaya muhalli. R-134a firiji ne wanda baya ɗauke da atomin chlorine, baya lalata layin ozone, kuma yana da kyakkyawan aikin aminci (mara ƙonewa, ba mai fashewa, ba mai guba, mara haushi, ba mai lalatawa), ƙarfin sanyaya sa da inganci Yana kusa da R-12 (dichlorodifluoromethane, Freon), don haka ana ɗaukarsa azaman madaidaicin madaidaicin madaidaicin madaidaicin madauki. R-134a a halin yanzu an amince da shi a duniya a matsayin mafi kyawun maye gurbin muhalli don R-12. Ba ya lalata ozone Layer kwata -kwata. Yana da firiji mai tsabtace muhalli wanda yawancin ƙasashe na duniya suka gane kuma suka ba da shawarar. Shi ne kuma na yanzu na al'ada muhalli m refrigerant. An yi amfani da shi sosai a farkon shigarwa da kuma kula da sabbin kayan sanyi da na’urar sanyaya iska. R134a yana da ƙarancin guba, ba mai ƙonewa a cikin iska, kuma yana da rukunin aminci na A1, wanda yake mai sanyi sosai. R134a galibi ana amfani da shi a fannoni da yawa, gami da: firiji, injin daskarewa, masu ba da ruwa, injin kwandishan na motoci, masu sanyaya iska ta tsakiya, masu dehumidifiers, ajiya mai sanyi, firiji na kasuwanci, injin ruwan kankara, injin ice cream, rabe -raben firiji da sauran kayan aikin firiji. Aerosol propellant, medical aerosol, kwari propellant, polymer (filastik) jiki kumfa wakili, da magnesium gami garkuwa gas, da dai sauransu R-134a za a iya amfani da ko'ina a matsayin refrigerant a mota kwandishan, firiji, tsakiyar kwandishan, firiji kasuwanci da sauran masana'antu, kuma ana iya amfani da su a cikin magunguna, magungunan kashe ƙwari, kayan shafawa, da masana'antun tsaftacewa. Karfin sinadaran R134a yana da kyau sosai. Koyaya, saboda narkar da ruwa ya fi na R22, ba shi da kyau ga tsarin firiji. Ko da akwai ruwa kaɗan, zai samar da acid, carbon dioxide ko carbon monoxide a ƙarƙashin aikin man mai. Ana samar da lalata ko “plating jan ƙarfe”, don haka R134a yana buƙatar bushewa mafi girma da tsabtace tsarin. R134a ba shi da wani maganin sinadarai tare da ƙarfe, baƙin ƙarfe, jan ƙarfe, aluminium da sauran karafa, kuma yana da ɗan tasiri akan zinc.
