Kunobva: China Chemical Indasitiri Nhau
Musi waMbudzi 23, webhusaiti yepamutemo yeBazi reEcology uye Zvemamiriro ekunze yakaburitsa "Inokurudzirwa Rondedzero yeHydrochlorofluorocarbon Substitutes muChina (Draft for Comment)" (inozonzi "Rondedzero"), ichikurudzira monochlorodifluoromethane (HCFC -22), 1 ,1-dichloro-1-fluoroethane (HCFC-141b), 1-chloro-1,1-difluoroethane (HCFC-142b) 24 yezvitatu zvikuru zvinogadzirwa uye zvakashandiswa mudzimba HCFCs 1 dzimwe nzira, kusanganisira nhanhatu dzeagent agent, kusanganisira carbon dioxide. , pentane, mvura, hexafluorobutene, trifluoropropene, tetrafluoropropene, zvichingodaro.
Munhu akakodzera anoona nezveMinistry of Ecology and Environment akati pari zvino kune marudzi maviri makuru edzimwe nzira dzeHCFCs: imwe ndeye hydrofluorocarbons (HFCs) ine high global warming potential (GWP), iyo yakashandiswa zvakanyanya munyika dzakabudirira kwemakore akawanda. , uye vakawanawo kugadzirwa kwakakura muChina.scale industrialization.Yechipiri ndeye yakaderera GWP kukosha inotsiva, kusanganisira yakasikwa inoshanda zvinwiwa, fluorine-ine olefins (HFO) uye zvimwe zvinhu.Kuti ukurudzire chirongwa chekubuda kweHCFCs, kubatanidza mhedzisiro yechikamu-kunze uye kutsiviwa kweHCFCs, uye kutungamira maindasitiri akakodzera nemabhizinesi kugadzira, kugadzira uye kushandisa girinhi uye yakaderera-kabhoni dzimwe nzira, Ministry of Ecology uye Environment. , pahwaro hwekupfupisa mhedzisiro yechikamu chekubuda kweHCFCs mumakore gumi apfuura, Kushandiswa kwemahydrocarbons (HCFCs) mumaindasitiri akasiyana, tichifunga nezvezvinhu zvakaita sekukura, kuwanikwa, uye kutsiva mhedzisiro yedzimwe nzira, dzakatsvagirwa uye kunyorwa. iyo "Inokurudzirwa Rondedzero yeHCFC-Ine Inotsiva muChina" (inozonzi "Rondedzero").Iyo "Rondedzero" inokurudzira dzimwe nzira uye mamwe matekinoroji akazivikanwa neindasitiri uye anotsigirwa neakabudirira ekushandisa mudzimba akatangira kana mapurojekiti ekuratidzira, uku ichikurudzira hunyanzvi uye kusimudzirwa kwedzimwe nzira dzeGWP dzakaderera.
Meng Qingjun, mutevedzeri wemunyori-mukuru weChina Plastics Processing Industry Association, muhurukuro nemutori wenhau kubva kuChina Chemical Industry News kuti “Rondedzero” inokurudzira kuti carbon dioxide ishandiswe panzvimbo peHCFCs sechinhu chinopupa furo re polystyrene foam ne polyurethane. kupfapfaidza furo, izvo zviri zviviri zvine hushamwari kwezvakatipoteredza uye zvine hupfumi, uye zvicharatidza zvirinani tarisiro yekushandisa.Mudanho rinotevera, mubatanidzwa uchashanda nesimba pamwe chete neBazi reEcology uye Zvemamiriro ekunze kusimbisa kusimudzirwa kwemamwe maajenti ekupupa furo kuitira kuti ive nechokwadi chekuenderera mberi kwekuita kwemaindasitiri e polyurethane uye polystyrene foam.
Xiang Minghua, general maneja weShaoxing Huachuang Polyurethane Co., Ltd., akataura kuti kutsiviwa kweHCFCs necarbon dioxide sechinhu chinopupuma furo repolurethane spray furo rakapfupikiswa mu "Rondedzero", izvo zvinounza mikana mitsva yebudiriro kukambani.Iyo kambani ichawedzera kukwidziridzwa kwekabhoni dioxide furo kupfapfaidza tekinoroji nemidziyo yekupa iyo indasitiri mhinduro dzakachengeteka, dzine hushamwari, dzinodhura.
Sun Yu, sachigaro weJiangsu Meside Chemical Co., Ltd., akataura kuti "14th-Makore mashanu Ekuvandudza Gwaro reChina's Polyurethane Indasitiri" inokurudzira kuti indasitiri yepolyurethane inofanira kuwedzera kusimudzira uye kushandiswa kwekombiki tekinoroji yekushanda, girinhi, yakachengeteka uye. zvakatipoteredza ushamwari additives.Shingairira kusimudzira kutsiva kweanopupa agent ODS.Sechikamu chinotungamira chine chekuita nekusimudzira nekushandisa tekinoroji yepolyurethane yekubatsira mukomboni muChina, Meside iri kubatsira kuona kutsiva kwevashoma-GWP vanopupa maajenti kuburikidza nekuvandudzwa uye kusimudzira kwe polyurethane surfactants (foam stabilizers) uye catalysts, uye kusimudzira yakaderera. -carbon uye kuchengetedzwa kwezvakatipoteredza kweindasitiri.
Parizvino, nyika yangu iri kuita chikamu chekubuda kwehydrochlorofluorocarbons (HCFCs) zvinoenderana nezvinodiwa neprotocol.Zvinoenderana nekugadziriswa kwe19th Protocol yeMusangano weMapato, nyika yangu inoda kumisa kugadzirwa uye kushandiswa kweHCFCs padanho rekutanga muna 2013, uye kuderedza danho rekutanga ne10%, 35% uye 67.5% panosvika 2015. 2020, 2025 uye 2030 zvichiteerana.% uye 97.5%, uye 2.5% yedanho rekutanga rakazochengeterwa kuchengetedza.Nekudaro, nyika yangu haisati yaburitsa rondedzero yakakurudzirwa yevanotsiva maHCFC.Sezvo kubviswa kweHCFC kwapinda padanho rakaomarara, maindasitiri akasiyana siyana nenzvimbo dzinoda hutungamiriri pane vanotsiva kuti ive nechokwadi chekuenderera mberi kweindasitiri nenyika.
