Raws li lub Xya Hli 1 lub sijhawm kawg yuav los txog, kev lag luam PU tawv ua npuas ncauj tau mus txog qhov tseem ceeb ntawm ib puag ncig- ua raws cov dej ntws. Raws li Ministry of Ecology thiab Ib puag ncig Daim Ntawv Tshaj Tawm No. 28 ntawm 2025, txij Lub Ib Hlis 1, 2026, kev tsim cov khoom siv polyols thiab polyurethane ua ntej siv HCFC-141b raws li tus neeg sawv cev tshuab yog txwv tsis pub, tshwj tsis yog cov tshuaj tsuag polyurethane ua npuas ncauj; txij Lub Xya Hli 1, 2026, kev tsim cov tshuaj tsuag polyurethane ua npuas ncauj siv HCFC-141b raws li tus neeg sawv cev tshuab yuav raug txwv.
Qhov no txhais tau hais tias premixed polyols thiab feem ntau cov khoom polyurethane twb tau nkag mus rau theem txiav npluav, thaum cov tshuaj tsuag tawv ua npuas ncauj tab tom yuav tawm ntawm nws qhov rais hloov tshiab. Rau kev lag luam, qhov no tsis yog ib qho teeb meem ntawm kev hloov mus rau lwm tus neeg ua haujlwm tshuab; nws yog ib qho system - kev hloov kho dav cuam tshuam rau cov qauv tsim, kev tsim khoom, kev tsim kho thiab kev ua raws li cov neeg siv khoom.
1. Txoj Cai Sijhawm Kawg Nkaus: Txau Nrho Ua Npuas Ncauj nkag mus rau nws lub qhov rais kawg hloov pauv
Hais txog lub sijhawm txoj cai, Lub Ib Hlis 1, 2026 yog thawj qhov pib, feem ntau yog tsom rau cov khoom siv polyols thiab polyurethane uas siv HCFC-141b ua tus neeg sawv cev tshuab. Raws li txoj cai, premixed -polyol producers, rigid-foam khoom manufacturers thiab lwm yam polyurethane khoom tuam txhab uas muag uas tsis yog tshuaj tsuag npuas yuav tsis tau txuas ntxiv siv HCFC-141b ua tus neeg sawv cev tshuab hauv ntau lawm.
Lub Xya hli ntuj 1 hnub kawg yog lub hom phiaj tshuaj tsuag polyurethane ua npuas ncauj khoom. Tsis zoo li lub Hoobkas- ua nruj- ua npuas ncauj boards, yeeb nkab plhaub thiab lwm yam khoom, cov tshuaj tsuag tawv ua npuas ncauj feem ntau tsim rau ntawm qhov chaw. Nws cov ntawv thov suav nrog kev rwb thaiv tsev, txias- rwb thaiv tsev cia, nuv ntses- lub nkoj rwb thaiv tsev, ru tsev waterproofing thiab rwb thaiv tsev, warehouse rwb thaiv tsev thiab ib co pipeline rwb thaiv tsev. Vim tias cov neeg koom nrog kev tsim kho tau tawg mus ntau dua, cov xwm txheej ntawm qhov project yog qhov nyuaj dua thiab cov kev tswj hwm txoj cai tau ntev dua, txoj cai yav dhau los tau tso cai rau lub sijhawm hloov mus ntev dua.
Pib txij Lub Xya Hli 1, txawm li cas los xij, qhov hloov pauv no tseem yuav kaw. Spray polyurethane ua npuas ncauj khoom siv HCFC-141b raws li tus neeg sawv cev tshuab yuav raug txwv los ntawm kev tsim khoom. Rau cov tshuaj tsuag- cov tuam txhab tsim kho, cov chaw muag khoom ua ntej-polyol thiab cov neeg siv khoom hauv qab, kev ua raws cai yuav hloov ntawm "kev hloov pauv" mus rau "yuav tsum tau hloov."
