Thaum Lub Xya Hli 2, 2025, nyob rau hauv txoj kab nrog nws cov lus cog tseg nyob rau hauv kev tiv thaiv ntawm ozone txheej thiab national txheej txheem ntawm cov tshuaj lom neeg- txheej txheem kev tswj hwm (HPMP) rau Polyurethane ua npuas ncauj Kev lag luam, Tuam Tshoj tshaj tawm ntawm Ecology thiab ib puag ncig ntawm daim ntawv ceeb toom sau ntawv ceeb toom npe hu ua:
"Cov lus tshaj tawm txog kev txwv tsis pub ntau lawm cov polyurethane cov khoom siv HCFC-141B raws li ib lub noob tus neeg sawv cev (cua ntsawj ntshab rau cov lus qhia rau pej xeem)".
Tom Qab
Kev lag luam polyurethane ua npuas ncauj tau yog ib qho ntawm cov neeg siv khoom tseem ceeb ntawm HCFCS (hydrochlorofluorocarbons) hauv Suav teb. Tau ntau xyoo, HCFC-141B, ib lub tshuab sawv cev nrog lub peev xwm siab high}} 2}}}), tau siv dav hauv cov khoom thermal rwb thaiv tsev. Ntawm tag nrho HCFCS, HCFC-141B muaj lub peev xwm ntau tshaj rau kev puas tsuaj.
Raws li lub tebchaws theem - out out phiaj, HCFC-141B yuav raug txwv tsis pub muaj nyob rau hauv Polyurethane Applications los ntawm 2026.

Nws yuav raug txwv los tsim cov polyethane khoom siv thiab cov khoom siv polyurethane siv HCFC-141B ua cov khoom siv tshuaj tsuag, tsuas yog rau cov khoom txau polyurethane ua npuas dej.
Kev tsim cov khoom lag luam xws li:
Tub yees thiab freezers
