Pa Novembara 23, tsamba lovomerezeka la Unduna wa Zachilengedwe ndi Zachilengedwe lidatulutsa "Mndandanda Wovomerezeka wa Hydrochlorofluorocarbon Substitutes ku China (Draft for Comment)" (pamenepa amatchedwa "List"), ndikulimbikitsa monochlorodifluoromethane (HCFC -22), 1 ,1-dichloro-1-fluoroethane (HCFC-141b), 1-chloro-1,1-difluoroethane (HCFC-142b) 24 mwa njira zitatu zazikulu zomwe zimapangidwa ndikugwiritsa ntchito HCFCs 1, kuphatikiza njira zina 6 zotulutsa thovu, kuphatikiza mpweya woipa. , pentane, madzi, hexafluorobutene, trifluoropropene, tetrafluoropropene, etc.
Munthu woyenerera yemwe amayang'anira Unduna wa Zachilengedwe ndi Zachilengedwe adati pakadali pano pali mitundu iwiri ikuluikulu ya njira zina za HCFC: imodzi ndi ma hydrofluorocarbons (HFCs) okhala ndi kutentha kwapadziko lonse lapansi (GWP), omwe akhala akugwiritsidwa ntchito kwambiri m'maiko otukuka kwazaka zambiri. , ndipo akwaniritsanso kupanga kwakukulu ku China.kukula kwa mafakitale.Chachiwiri ndi malo otsika a GWP, kuphatikizapo madzi achilengedwe ogwirira ntchito, olefins okhala ndi fluorine (HFO) ndi zinthu zina.Pofuna kulimbikitsa njira yochotsera ma HCFC, kuphatikiza zotsatira za kuchotsedwa ndi kusintha kwa ma HCFC, ndikuwongolera mafakitale ndi mabizinesi oyenera kupanga zatsopano, kupanga ndi kugwiritsa ntchito njira zina zobiriwira komanso zotsika kaboni, Unduna wa Zachilengedwe ndi Zachilengedwe. , pamaziko ofotokozera mwachidule zotsatira za kutuluka kwa ma HCFC m'zaka khumi zapitazi, Kugwiritsa ntchito ma hydrocarbon (HCFCs) m'mafakitale osiyanasiyana, poganizira zinthu monga kukhwima, kupezeka, ndi kusintha kwa njira zina, zofufuzidwa ndi kulembedwa. "Mndandanda Wolangizidwa wa HCFC-Muli M'malo ku China" (pamenepa umatchedwa "Mndandanda") )."Mndandanda" umalimbikitsa njira zina ndi njira zamakono zomwe zadziwika ndi makampani komanso kuthandizidwa ndi zochitika zogwirira ntchito zapakhomo kapena mapulojekiti owonetserako, pamene akulimbikitsa kukonzanso ndi kupititsa patsogolo njira zochepetsera GWP.
Meng Qingjun, wachiwiri kwa mlembi wamkulu wa China Plastics Processing Industry Association, poyankhulana ndi mtolankhani wochokera ku China Chemical Industry News kuti "Mndandanda" umalimbikitsa kuti mpweya woipa wa carbon dioxide ugwiritsidwe ntchito m'malo mwa HCFC monga thovu la polystyrene ndi polyurethane. thovu lopopera, lomwe ndi lokonda zachilengedwe komanso lopanda ndalama, ndipo liwonetsa chiyembekezo chogwiritsa ntchito bwino.Mu sitepe yotsatira, bungweli ligwirizana kwambiri ndi Unduna wa Zachilengedwe ndi Zachilengedwe kulimbikitsa kukwezedwa kwazinthu zina zotulutsa thovu kuti ziwonetsetse kuti mafakitale a thovu a polyurethane ndi polystyrene akugwira ntchito mosalekeza.
Xiang Minghua, manejala wamkulu wa Shaoxing Huachuang Polyurethane Co., Ltd., adati m'malo mwa HCFCs ndi mpweya woipa wa carbon dioxide ngati wothandizira thovu la thovu lopopera la polyurethane adasankhidwa mu "List", zomwe zidzabweretse mwayi watsopano wa chitukuko ku kampani.Kampaniyo idzawonjezera kukwezeleza kwaukadaulo wopopera thovu wa carbon dioxide ndi zida kuti apatse makampaniwo njira zotetezeka, zoteteza zachilengedwe, zotsika mtengo.
Sun Yu, wapampando wa Jiangsu Meside Chemical Co., Ltd., adati "14th Year Five Development Guide for China's Polyurethane Viwanda" ikufuna kuti makampani a polyurethane awonjezere chitukuko ndi kugwiritsa ntchito ukadaulo wamagulu ogwirira ntchito, obiriwira, otetezeka komanso otetezeka. zachilengedwe wochezeka zowonjezera.Limbikitsani mwachangu m'malo mwa ODS yotulutsa thovu.Monga gawo lotsogola lomwe limayang'anira chitukuko ndi kugwiritsa ntchito ukadaulo wowonjezera wa polyurethane ku China, Meside ikuthandizira kuzindikira m'malo mwa otsitsa thovu a GWP kudzera mwaukadaulo ndi kukweza kwa polyurethane surfactants (foam stabilizers) ndi zothandizira, ndikulimbikitsa otsika. - carbon ndi kuteteza chilengedwe cha makampani.
Pakali pano, dziko langa likugwira ntchito yochotsa ma hydrochlorofluorocarbons (HCFCs) mogwirizana ndi zofunikira za ndondomekoyi.Malinga ndi chigamulo cha 19th Protocol of the Conference of the Parties, dziko langa liyenera kuyimitsa kupanga ndi kugwiritsira ntchito ma HCFC pamlingo woyambira mu 2013, ndikuchepetsa gawo loyambira ndi 10%, 35% ndi 67.5% pofika 2015, 2020, 2025 ndi 2030 motsatana.% ndi 97.5%, ndipo 2.5% ya gawo loyambira idasungidwa kuti ikonzedwe.Komabe, dziko langa silinaperekebe mndandanda wovomerezeka wa m'malo mwa ma HCFC.Popeza kuthetsedwa kwa ma HCFC kwafika pamlingo wovuta kwambiri, mafakitale ndi madera osiyanasiyana akufunika chitsogozo chaolowa m'malo kuti awonetsetse kuti bizinesi ndi dziko zikuyenda bwino.
