Theem theem kev ntawm cov lag luam ntau lawm tau nce ceev ceev heev.
Raws li lawv lub cev qhov ua tau zoo, HFC tau siv dav hauv tub yees (suav nrog cov tub yees ntawm hydrofluorocarbons), aerosols, cov tua hluav taws, cov tshuaj tua kab, cov tshuaj tua kab, cov tshuaj ntxuav tu, thiab lwm yam. Txog tam sim no, theem kev ntawm kev txhim kho txuj ci ntau lawm thiab kev tsim khoom lag luam xws li Juhua Group, Shandong Dongyue Chemical Co., Ltd., Sinochem Blue Ntuj Group Co., Ltd., Changshu Sanaifu Zhongyu Tshuaj Tshiab Tshuaj Co., Ltd. thiab cov tshuaj fluorine. tshuaj lom neeg kev lag luam hauv lub sijhawm xyoo 1990 cov tuam txhab yog nyob rau tib theem. Cov HFC tam sim no tsim tawm ntawm cov ntsuas kev lag luam suav nrog HFC-134a (Cov Tub Yees Hluav Taws Xob R134a rau siv tau), HFC-32, HFC-125, HFC-152a (Cov Roj Tub Yees R152a), HFC-143a, HFC-227ea, HFC-245fa (Tshuab Tus Neeg Sawv Cev R245fa) thiab HFC 236fa (Cov Hluav Taws Kub Extinguishing Agent R236fa). Hauv xyoo 2016, HFC-125 (pentafluoroethane) muaj lub peev xwm loj tshaj plaws, kwv yees li 278,000 tons / xyoo, xam txog 30% ntawm tag nrho HFCs lub peev xwm.
Txij li xyoo 2014, cov peev txheej tsim tawm thiab cov khoom siv ntawm HFC-125 thiab HFC-32 tau nce siab dua vim HCFC-22 nkag mus rau cov txheej txheem thiab theem kev lag luam rau R410A (Cov Tub Yees R410a rau cov cua txias thiab cov cua kub twj tso kua mis) tau nthuav dav sai. Cov khoom tsim tau ntawm HFC-125 thiab HFC32 tau nce los ntawm 144,000 tons / xyoo thiab 125,000 tons / xyoo hauv 2013 txog 278,000 tons / xyoo thiab 249,000 tons / xyoo hauv 2016.
Cov ntsiab lus ntawm Tuam Tshoj HFCs kev lag luam hauv 2016 tau qhia nyob rau hauv Table 2
