Thaum Lub Kaum Ib Hlis 23, lub vev xaib raug cai ntawm Ministry of Ecology thiab Ib puag ncig tau tshaj tawm "Cov Ntawv Pom Zoo Ntawm Hydrochlorofluorocarbon Hloov Hauv Suav Teb (Draft for Comment)" (tom qab no hu ua "Sau"), pom zoo rau monochlorodifluoromethane (HCFC -22), 1 , 1-dichloro-1-fluoroethane (HCFC-141b), 1-chloro-1,1-difluoroethane (HCFC-142b) 24 ntawm peb lub ntsiab tseem ceeb hauv tsev tsim thiab siv HCFCs 1 lwm txoj hauv kev, suav nrog 6 tus neeg sawv cev foaming, suav nrog carbon dioxide. , pentane, dej, hexafluorobutene, trifluoropropene, tetrafluoropropene, thiab lwm yam.
Tus neeg cuam tshuam los ntawm Ministry of Ecology thiab Ib puag ncig tau hais tias tam sim no muaj ob hom kev hloov pauv tseem ceeb ntawm HCFCs: ib qho yog hydrofluorocarbons (HFCs) nrog lub ntiaj teb ua kom sov siab (GWP), uas tau siv dav hauv cov tebchaws tsim tau ntau xyoo. , thiab kuj tau ua tiav cov khoom loj hauv Suav teb.scale industrialization.Qhov thib ob yog qhov qis GWP tus nqi hloov pauv, suav nrog cov kua dej ua haujlwm, muaj fluorine-muaj olefins (HFO) thiab lwm yam khoom.Txhawm rau txhawb nqa cov txheej txheem theem-tawm ntawm HCFCs, sib sau ua ke cov txiaj ntsig ntawm theem tawm thiab hloov HCFCs, thiab coj cov kev lag luam thiab cov lag luam cuam tshuam rau kev tsim kho tshiab, tsim thiab siv ntsuab thiab cov pa roj carbon tsawg, Ministry of Ecology thiab Ib puag ncig. Raws li kev txheeb xyuas cov txiaj ntsig ntawm theem-tawm ntawm HCFCs hauv kaum xyoo dhau los, Kev siv cov hydrocarbons (HCFCs) hauv ntau qhov kev lag luam, xav txog yam xws li kev loj hlob, muaj, thiab kev hloov pauv los ntawm lwm txoj kev, tshawb nrhiav thiab tsim qauv "Cov Ntawv Pom Zoo ntawm HCFC-muaj Cov Hloov Pauv hauv Suav Teb" (tom qab no hu ua "Tsev Npe") ).Cov "Tsev Npe" pom zoo rau lwm txoj hauv kev thiab lwm yam thev naus laus zis uas tau lees paub los ntawm kev lag luam thiab kev txhawb nqa los ntawm kev ua tiav kev siv hauv tsev ua ntej lossis ua qauv qhia, thaum txhawb kev tsim kho tshiab thiab txhawb nqa cov kev hloov qis-GWP.
Meng Qingjun, Tus Lwm Thawj Coj ntawm Tuam Tshoj Plastics Processing Industry Association, tau hais hauv kev xam phaj nrog tus neeg sau xov xwm los ntawm Tuam Tshoj Tshuaj Kev Lag Luam Xov Xwm hais tias "Daim ntawv teev npe" pom zoo kom siv cov pa roj carbon dioxide es tsis txhob siv HCFCs ua tus neeg sawv cev foaming rau extruded polystyrene ua npuas ncauj thiab polyurethane. spray ua npuas ncauj, uas yog ob qho tib si ib puag ncig tus phooj ywg thiab kev lag luam, thiab yuav ua rau pom kev zoo dua daim ntawv thov.Hauv cov kauj ruam tom ntej, lub koom haum yuav koom tes nrog Ministry of Ecology thiab Ib puag ncig los ntxiv dag zog rau kev txhawb nqa ntawm lwm cov neeg ua npuas ncauj kom ntseeg tau tias kev ua haujlwm tsis tu ncua ntawm polyurethane thiab polystyrene ua npuas ncauj kev lag luam.
Xiang Minghua, tus thawj coj ntawm Shaoxing Huachuang Polyurethane Co., Ltd., tau hais tias kev hloov HCFCs los ntawm cov pa roj carbon dioxide raws li tus neeg sawv cev foaming rau polyurethane spray ua npuas ncauj yog shortlisted nyob rau hauv "Tsev", uas yuav coj txoj kev loj hlob tshiab rau lub tuam txhab.Lub tuam txhab yuav nce qib ntawm cov pa roj carbon dioxide ua npuas ncauj txau tshuab thiab cov cuab yeej siv los muab kev lag luam nrog kev nyab xeeb, kev nyab xeeb ntawm ib puag ncig, kev daws teeb meem zoo.
Sun Yu, tus thawj coj ntawm Jiangsu Meside Chemical Co., Ltd., tau hais tias "14th Tsib Xyoo Kev Txhim Kho Phau Ntawv Qhia rau Tuam Tshoj Polyurethane Kev Lag Luam" qhia tias kev lag luam polyurethane yuav tsum nce kev txhim kho thiab siv cov cuab yeej sib xyaw rau kev ua haujlwm, ntsuab, nyab xeeb thiab environmentally friendly additives.Txhawb kev hloov pauv ntawm tus neeg sawv cev foaming ODS.Raws li lub tuam txhab ua lub luag haujlwm rau kev txhim kho thiab kev siv cov tshuab polyurethane auxiliary compound technology hauv Suav teb, Meside tab tom pab kom paub txog kev hloov cov low-GWP foaming agents los ntawm kev tsim kho tshiab thiab kho dua tshiab ntawm polyurethane surfactants (foam stabilizers) thiab catalysts, thiab txhawb qhov qis. -carbon thiab kev tiv thaiv ib puag ncig ntawm kev lag luam.
Tam sim no, kuv lub teb chaws tab tom ua cov theem tawm ntawm hydrochlorofluorocarbons (HCFCs) raws li cov cai ntawm cov txheej txheem.Raws li qhov kev daws teeb meem ntawm 19th Txoj Cai ntawm Lub Rooj Sib Tham ntawm Cov Neeg Sib Tham, kuv lub teb chaws yuav tsum tau tso tseg kev tsim khoom thiab kev siv HCFCs nyob rau theem pib hauv xyoo 2013, thiab txo qis theem pib los ntawm 10%, 35% thiab 67.5% los ntawm 2015, 2020, 2025 thiab 2030 feem.% thiab 97.5%, thiab 2.5% ntawm cov theem pib thaum kawg tau khaws tseg rau kev saib xyuas.Txawm li cas los xij, kuv lub tebchaws tseem tsis tau tshaj tawm cov npe pom zoo hloov pauv rau HCFCs.Raws li kev tshem tawm HCFCs tau nkag mus rau theem tseem ceeb, ntau yam kev lag luam thiab cov cheeb tsam xav tau kev taw qhia txog kev hloov pauv kom ntseeg tau tias kev ua haujlwm tsis tu ncua ntawm kev lag luam thiab lub teb chaws.
