Indasteri ea lisebelisoa tsa lapeng e felisitse ka botlalo sehatsetsi sa R22 nakong ea ho bala
Ho ea ka Montreal Protocol, sehatsetsi sa R22 se emisitsoe linaheng tse tsoetseng pele 'me se ntse se ka hlahisoa linaheng tse tsoelang pele, empa nako ea ho hlahisa le ho se sebelisa ke 2030.
Ka la 26 Pherekhong 2021, Lekala la Ecology le Tikoloho le ile la fana ka Tsebiso mabapi le Phano ea Likarolo tsa Tlhahiso, Tšebeliso le ho Kena ka 2021 bakeng sa Lintho Tse Felisang Ozone (eo ka mor'a moo e tla bitsoa Tsebiso). Ho latela Molao oa Rephaboliki ea People of China mabapi le Thibelo le Taolo ea Tšilafalo ea Moea, Melawana ea Tsamaiso ea Lintho tse Felisang Lera la Ozone le lipehelo tse ling tse amehang, likhoebo tse 20 li tla fuoa tlhahiso ea lithane tse 292,795 tsa hydrochlorofluorocarbons ( HCFC) ka 2021, mme likarolo tse 46 li tla fuoa palo ea tšebeliso ea lithane tse 31,726 tsa hydrochlorofluorocarbons ka 2021.
Ha ho bapisoa le 2020, palo ea tlhahiso ea hydrochlorofluorocarbons (HCFCS) ho kenyeletsoa HCFC-22 e tla lula e sa fetohe ka 2021, athe palo ea ts'ebeliso e tla fokotsoa haholo, 'me e felise HCFCS hape indastering ea lisebelisoa tsa lapeng ea China.
Karolo ea tlhahiso e nang le hCFC (HCFC) e tla fanoa bakeng sa hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 le HCFC-133A. Har'a tsona, HCFC-141B ke sesebelisoa se phophomang metsi se sebelisoang indastering ea sehatsetsi le e futhumatsang metsi. Ha mokhoa oa ho phophoma ka har'a indasteri ea sehatsetsing o ntlafalitsoe ho ba HFC-245FA + cyclopentane foaming system, mme ka la 1 Pherekhong 2019, indasteri ea futhumatsang metsi e thibetse ts'ebeliso ea HCFC-141B ka botlalo. Hcfc-141b e 'nile ea sebelisoa hanyane ka hanyane indastering ea lisebelisoa tsa lapeng. Kakaretso ea kakaretso ea tlhahiso ea hCFC-141B ka 2021 ke lithane tse 50,878, tse sa fetoheng ho tloha 2020.
Ha ho bapisoa le palo ea tlhahiso ea HCFC-22, kakaretso ea ts'ebeliso ea hCFC-22 indastering ea moea oa lapeng ka 2021 ke lithane tse 31,726, e leng phokotseho ea lithane tse 3,489 ho tloha ho lithane tse 35,215 ka 2020. Sena se amana haufi-ufi le switjha ea sehatsetsing ka har'a sehatsetsing. indasteri ea ho futhumatsa moea ka lapeng. Kabelo ea 'maraka ea li-conditioner tsa HCFC-22 indastering ea li-air conditioning tsa lapeng e ne e le hoo e ka bang 20% ka 2019,' me karolo ena e tla tsoela pele ho theoha ka 2020. Indasteri ea lehae ea naha ea Chaena e entse katleho e tsotehang ho felisa HCFC-22.
Leano la taolo la HCFC-22 la ho kgaotsa bakeng sa indasteri ya Nagae ya ho futhumatsa moya naheng ya China ho tloha ka 2021 ho isa ho 2026 le tjhaellwa monwana ke Komiti ya Phethahatso ya Letlole la Dinaha tse ngata, mme e ikemiseditse ho fedisa tshebediso ya 70% ya hCFC-22 ka 2026, eo e feta kamoo ho hlokehang kemiso ea Montreal Protocol ho fihlela phokotso ea hCFC-22. Re tla kenya letsoho ho feta ho kenngweng tshebetsong ha China ha Porothokhole ya Montreal.
