Ma ka lā 23 o Nowemapa, ua hoʻokuʻu ka pūnaewele mana o ka Ministry of Ecology and Environment i ka "Recommended List of Hydrochlorofluorocarbon Substitutes in China (Draft for Comment)" (i kapa ʻia ʻo "List"), e paipai ana i ka monochlorodifluoromethane (HCFC -22), 1 ,1-dichloro-1-fluoroethane (HCFC-141b), 1-chloro-1,1-difluoroethane (HCFC-142b) 24 o nā mea nui ʻekolu i hana ʻia a hoʻohana ʻia nā HCFC 1 ʻokoʻa, me 6 mau mea hoʻohāhā, me ka carbon dioxide. , pentane, wai, hexafluorobutene, trifluoropropene, tetrafluoropropene, etc.
ʻO ka mea kūpono i mālama i ka Ministry of Ecology and Environment i ʻōlelo ʻia aia i kēia manawa ʻelua ʻano nui o nā koho HCFC: hoʻokahi hydrofluorocarbons (HFCs) me ka hiki ke hoʻomehana honua kiʻekiʻe (GWP), i hoʻohana nui ʻia i nā ʻāina hoʻomohala no nā makahiki he nui. , a ua hoʻokō pū i ka hana nui ma Kina.hoʻonaʻauao pālākiō.ʻO ka lua, he mau mea pani waiwai GWP haʻahaʻa, me nā wai hana maoli, nā olefins i loko o ka fluorine (HFO) a me nā mea ʻē aʻe.I mea e paipai ai i ke kaʻina hana hoʻopau ʻana o nā HCFC, e hoʻohui i nā hopena o ka haʻalele ʻana a me ka pani ʻana i nā HCFC, a alakaʻi i nā ʻoihana kūpono a me nā ʻoihana e hana hou, hoʻomohala a hoʻohana i nā ʻōmaʻomaʻo a me nā kalapona haʻahaʻa, ke Kuhina o Ecology a me Environment. , ma ke kumu o ka hōʻuluʻulu ʻana i nā hopena o ka haʻalele ʻana o nā HCFC i nā makahiki he ʻumi i hala, ʻO ka hoʻohana ʻana i nā hydrocarbons (HCFCs) i nā ʻoihana like ʻole, e noʻonoʻo ana i nā kumu e like me ke oʻo ʻana, loaʻa, a me nā hopena pani o nā mea ʻokoʻa, noiʻi ʻia a hoʻolālā ʻia. ʻO ka "Papa Manaʻo ʻia o nā mea pani HCFC-Loaʻa i Kina" (i kapa ʻia ʻo "List") ).Manaʻo ka "List" i nā mea ʻē aʻe a me nā ʻenehana ʻē aʻe i ʻike ʻia e ka ʻoihana a kākoʻo ʻia e nā hoʻohana mua ʻana o ka home a i ʻole nā papahana hōʻikeʻike, ʻoiai e paipai ana i ka hana hou a me ka hoʻolaha ʻana i nā koho haʻahaʻa-GWP.
Ua ʻōlelo ʻo Meng Qingjun, ka hope kākau ʻōlelo nui o China Plastics Processing Industry Association, i loko o kahi hālāwai ninaninau me kahi mea kākau moʻolelo mai China Chemical Industry News e ʻōlelo ana ka "List" e hoʻohana ʻia ka carbon dioxide ma mua o nā HCFC ma ke ʻano he mea hoʻohua no ka extruded polystyrene foam a me ka polyurethane. ʻO ka pulupulu hoʻoheheʻe, ʻo ia ka mea pili i ke kaiapuni a me ka hoʻokele waiwai, a e hōʻike ana i kahi ʻoi aku ka maikaʻi o ka noi.I ka hana aʻe, e hui pū ka hui me ka Ministry of Ecology and Environment e hoʻoikaika i ka hoʻolaha ʻana i nā mea hoʻoulu ʻē aʻe kūpono e hōʻoia i ka hana mau ʻana o ka ʻoihana polyurethane a me ka polystyrene foam.
Ua ʻōlelo ʻo Xiang Minghua, ka luna nui o Shaoxing Huachuang Polyurethane Co., Ltd., ʻo ka hoʻololi ʻana o nā HCFC e ka carbon dioxide ma ke ʻano he mea hoʻohāhā no ka polyurethane spray foam i koho pōkole ʻia ma ka "List", e lawe mai i nā manawa hoʻomohala hou i ka hui.E hoʻonui ka hui i ka hoʻolaha ʻana i ka ʻenehana hoʻoheheʻe carbon dioxide a me nā mea hana e hoʻolako i ka ʻoihana me nā hopena palekana, pili i ke kaiapuni, nā kumu kūʻai.
Ua ʻōlelo ʻo Sun Yu, ka luna o Jiangsu Meside Chemical Co., Ltd., ʻo ka "14th Five-Year Development Guide for China's Polyurethane Industry" e manaʻo e hoʻonui ka ʻoihana polyurethane i ka hoʻomohala ʻana a me ka hoʻohana ʻana i ka ʻenehana composite no ka hana, ʻōmaʻomaʻo, palekana a nā mea hoʻohui pili kaiapuni.Hoʻoikaika ikaika i ka hoʻololi ʻana i ka mea hoʻohāhā ODS.Ma ke ʻano he alakaʻi alakaʻi no ka hoʻomohala ʻana a me ka hoʻohana ʻana i ka ʻenehana hui kōkua polyurethane ma Kina, ke kōkua nei ʻo Meside e hoʻomaopopo i ka hoʻololi ʻana o nā mea hoʻoheheʻe haʻahaʻa-GWP ma o ka hana hou a me ka hoʻomaikaʻi ʻana i nā polyurethane surfactants (foam stabilizers) a me nā catalysts, a hoʻolaha i ka haʻahaʻa. -ʻo ke kalapona a me ke kaiapuni o ka ʻoihana.
I kēia manawa, ke hoʻokō nei koʻu ʻāina i ka hoʻopau ʻana i nā hydrochlorofluorocarbons (HCFCs) e like me nā koi o ka protocol.Wahi a ka ʻōlelo hoʻoholo o ka 19th Protocol of the Conference of the Party, pono koʻu ʻāina e hoʻokuʻu i ka hana a me ka hoʻohana ʻana i nā HCFC ma ka pae baseline ma 2013, a hoʻemi i ka pae baseline e 10%, 35% a me 67.5% e 2015, 2020, 2025 a me 2030.% a me 97.5%, a me 2.5% o ka pae kumu i hoʻopaʻa ʻia no ka mālama.Akā naʻe, ʻaʻole i hoʻopuka koʻu ʻāina i kahi papa inoa o nā mea pani no nā HCFC.I ke komo ʻana o ka hoʻopau ʻia ʻana o nā HCFC i kahi kūlana koʻikoʻi, makemake nui nā ʻoihana like ʻole a me nā wahi i ke alakaʻi ʻana i nā mea pani e hōʻoia i ka hana mau o ka ʻoihana a me ka ʻāina.
