PFAS-feem ntau hu ua "tshuaj lom neeg mus ib txhis" - yog nyob rau hauv kev tshuaj xyuas thoob ntiaj teb tsis tau pom dua. Nrog rau EU Txoj Cai Ntim thiab Ntim Cov Khoom Pov Tseg (PPWR, 2025) txwv tsis pub PFAS hauv cov khoom noj-hu rau lub ntim pib txij lub Yim Hli 2026, thiab US EPA PFAS Action Plan (2021-2024) nruj txwv hla kev lag luam, cov tuam txhab extrusion raug cuam tshuam los hloov cov txheej txheem fluoropolys (PFAS-free) lwm txoj
Vim li cas thiaj tsim nyogtshem tawm PFAS hauv polymer extrusion?
Per- thiab polyfluoroalkyl tshuaj (PFAS), ib pab pawg ntawm cov tshuaj endocrine cuam tshuam tsis tu ncua, thiab txuas rau mob qog noj ntshav, kab mob thyroid, thiab cov teeb meem kev loj hlob. PFAS tau siv rau hauv kev lag luam thiab cov khoom siv txij li xyoo 1940s. PFAS yog ubiquitous nyob rau hauv ib puag ncig vim lawv cov tshuaj ruaj khov qauv. Raws li lub npe hu ua "tshuaj lom neeg mus ib txhis", lawv tau pom hauv av, dej, thiab huab cua.8 Tsis tas li ntawd, PFAS tau pom nyob rau hauv ntau yam khoom (xws li, cov khoom siv uas tsis yog khoom siv, cov ntaub stain-resistant, firefighting foams), khoom noj khoom haus, thiab dej haus, uas ua rau yuav luag tag nrho cov pej xeem (> 95%).
Yog li, PFAS kev sib kis tau ua rau cov kev cai nruj dua rau lawv siv hauv cov khoom siv polymer extrusion. Rau zaj duab xis, yeeb nkab, thiab cable manufacturers, tsoos PPAs ua rau muaj kev pheej hmoo ntawm ob qho tib si kev ua raws cai thiab lub koob npe nrov.
Hauv qab no yog cov kev hloov pauv tshwj xeeb thiab cov kev pib ua rau kev hloov pauv no, raws li cov ntaub ntawv muaj:
1. European Union (EU) Kev Cai Ua Haujlwm:
• ECHA's Proposed PFAS Restriction (2023): Thaum Lub Ob Hlis 2023, European Chemicals Agency (ECHA) tau thov kom muaj kev txwv dav dav rau cov tshuaj per- thiab polyfluoroalkyl (PFAS) raws li kev cai REACH. Lub tswv yim tsom mus rau ntau yam ntawm PFAS, suav nrog fluoropolymers siv los ua cov khoom siv polymer (PPAs). Thaum lub lag luam fluoropolymer tab tom nrhiav kev zam, cov kev cai tswj hwm yog qhov tseeb: cov kev txwv tau raug tsav los ntawm ib puag ncig tsis tu ncua thiab muaj peev xwm noj qab haus huv ntawm PFAS. Lub hom phiaj yog txhawm rau txwv lawv cov khoom tsim, siv, thiab tso rau hauv kev ua lag luam, yog li ua rau kev lag luam txais PFAS-dawb lwm txoj hauv kev.
• EU Chemicals Strategy for Sustainability: EU lub tswv yim siv txoj hauv kev zoo los tswj PFAS kev pheej hmoo, ua ntej theem ntawm cov khoom tsis zoo thiab txhawb kev tsim cov tshuaj fluorine-dawb lwm txoj hauv kev, suav nrog cov txheej txheem polymer. Qhov no tau ua kom muaj kev tsim kho tshiab hauv PFAS-dawb PPAs, tshwj xeeb yog txhawm rau ua raws li kev sib cuag nrog zaub mov thiab ntim cov cai.
• European Union Ntim thiab Ntim Ntim Cov Cai (PPWR) 2025: Tshaj tawm hauv European Official Journal thaum Lub Ib Hlis 22, 2025, PPWR suav nrog kev txwv tsis pub siv PFAS hauv kev ntim khoom noj pib txij lub Yim Hli 12, 2026. Txoj cai tswj hwm lub hom phiaj los txo cov kev cuam tshuam ib puag ncig ntawm kev ntim khoom thiab kev tiv thaiv PFAS. kev pab siv nyob rau hauv yas zaj duab xis extrusion. Tsis tas li ntawd, PPWR hais txog qhov yuav tsum tau rov ua dua tshiab - thaj chaw uas PFAS-dawb PPAs muab qhov txiaj ntsig zoo - yog li txhawb ntxiv kev hloov pauv mus rau cov kev daws teeb meem ntim tau zoo.
2. Teb Chaws Asmeskas Txoj Cai Kev Txhim Kho
• EPA's PFAS Action Plan (2021–2024): US Environmental Protection Agency (EPA) tau siv ntau yam kev ntsuas los daws cov kab mob PFAS:
• Kev Tsim PFOA thiab PFOS ua Cov Khoom Uas Muaj Teeb Meem (Lub Plaub Hlis 2024): Raws li Kev Ua Haujlwm Zoo Ib puag ncig, Kev them nyiaj, thiab kev lav phib xaub (Superfund), EPA tsim cov tshuaj perfluorooctanoic acid (PFOA) thiab perfluorooctanesulfonic acid (PFOS)—cov PPAs tseem ceeb hauv cov khoom siv. Qhov no ua rau kom muaj pob tshab thiab kev lav phib xaub rau kev ntxuav thiab txhawb kev lag luam kom hloov mus rau lwm qhov tsis yog PFAS.
• National Drinking Water Standard (Plaub Hlis 2024): EPA tau ua tiav thawj tus qauv dej haus uas raug cai rau PFAS, txhawm rau txo qhov raug rau kwv yees li 100 lab tus tib neeg. Txoj cai no txwv tsis pub muaj kev lag luam kom tshem tawm PFAS los ntawm cov txheej txheem tsim khoom, suav nrog PPAs, txhawm rau tiv thaiv cov dej paug.
• Toxics Release Inventory (TRI) Ntxiv (Lub Ib Hlis 2024): EPA tau ntxiv xya PFAS rau TRI raws li Txoj Cai Tiv Thaiv Kev Tiv Thaiv Hauv Lub Tebchaws 2020, xav kom tshaj tawm rau xyoo 2024. Qhov no ua rau muaj kev tshuaj xyuas ntau ntxiv ntawm PFAS-muaj PPAs thiab txhawb kom muaj kev saws me nyuam.
• Txoj Cai Tiv Thaiv Kev Tiv Thaiv thiab Rov Qab Los (RCRA) Cov Lus Pom Zoo (Lub Ob Hlis 2024): EPA tau thov cov cai ntxiv cuaj PFAS rau hauv cov npe ntawm cov neeg muaj kev phom sij nyob rau hauv RCRA, txhim kho txoj cai huv thiab txuas ntxiv thawb cov tuam txhab mus rau PFAS-dawb cov kev daws teeb meem.
• Lub Xeev-Level Bans: Cov xeev xws li Minnesota tau siv cov kev txwv tsis pub muaj PFAS cov khoom, xws li cov khoom noj khoom haus, qhia txog kev nthuav dav dav rau PFAS-raws li cov ntaub ntawv, suav nrog PPAs siv hauv cov ntawv thov zaub mov. Lwm lub xeev, suav nrog California, Michigan, thiab Ohio, tau hais txog qhov tsis muaj tsoomfwv txiav txim siab ua tus tsav tsheb rau lub xeev-qib PFAS cov cai, ntxiv txhawb kev hloov mus rau PFAS-dawb PPAs.
3. Ntiaj teb no thiab Regional Initiatives:
• Canada Txoj Cai Tswjfwm Ntiag Tug: Canada tau tsim cov kev cai muaj zog los txo thiab tswj PFAS ntau lawm thiab siv, cuam tshuam rau cov tuam txhab lag luam thoob ntiaj teb los hloov PFAS-raws li PPAs nrog lwm yam tsis muaj fluorine.
• Stockholm Convention: Kev sib tham thoob ntiaj teb ntawm PFAS txoj cai, tshwj xeeb tshaj yog rau perfluorooctanesulfonic acid (PFOS) thiab lwm yam sib txuas, tau ua tsis tu ncua rau ntau tshaj kaum xyoo. Txawm hais tias tsis yog txhua lub tebchaws (xws li, Brazil thiab Tuam Tshoj) txwv tsis pub muaj qee yam PFAS, lub ntiaj teb hloov mus rau kev tswj hwm txhawb nqa kev txais yuav PFAS-dawb PPAs.
• 3M's Phase-Out Commitment (2022): 3M, lub chaw tsim khoom loj PFAS, tshaj tawm tias nws yuav tso tseg PFAS ntau lawm thaum kawg ntawm 2025, ua rau muaj kev xav tau ntau rau cov tsis-PFAS PPAs los hloov cov fluoropolymer-based pab hauv kev lag luam xws li zaj duab xis thiab yeeb nkab extrusion
4. Kev Ua Raws Li Khoom Noj Khoom Haus:
Cov kev cai los ntawm US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA) hais txog PFAS-dawb PPAs rau cov ntawv thov zaub mov.
5. Kev Lag Luam & Kev Lag Luam Siab
Tshaj li txoj cai tswjfwm, cov neeg siv khoom xav tau rau cov khoom lag luam hauv eco-friendly thiab cov hom phiaj kev lag luam ruaj khov yog thawb cov tswv lag luam thiab cov tuam txhab lag luam kom txais PFAS-dawb PPAs. Qhov no yog qhov tseeb tshwj xeeb hauv kev lag luam ntim khoom, qhov twg PFAS-dawb cov kev daws teeb meem yog nrhiav kev ntim khoom yooj yim, cua tshuab, thiab cam khwb cia cov yeeb yaj kiab kom ua tau raws li kev xav tau ntawm kev lag luam thiab zam kev puas tsuaj rau lub koob npe nrov.
Kev lag luam teb: PFAS-dawb PPAs
Cov khoom lag luam tseem ceeb ntawm cov khoom siv polymer xws li Silike, Clariant, Baerlocher, Ampacet, thiab Tosaf tau teb los ntawm kev tsim PFAS-dawb PPAs uas phim lossis tshaj qhov kev ua tau zoo ntawm fluoropolymer-based pab. Cov kev xaiv no pab txo cov pob txha tawg, tuag tsim, thiab extrusion siab, thaum ua kom muaj kev ua raws li cov cai tswj kev noj zaub mov thiab txhawb cov hom phiaj kev ruaj ntseg.
Piv txwv li,Silike SILIMER Series Polymer Extrusion Additives muaj PFAS dawb, cov tshuaj tsis muaj fluorinekom kov yeej cov kev sib tw ua. Tsim los rau tshuab, cam khwb cia, thiab multilayer films, fibers, cables, kav, masterbatch, compounding, thiab lwm yam, nws muaj peev xwm txhim khu kev ua tau zoo ntawm ntau yam ntawm polyolefins, xws li tab sis tsis txwv rau mLLDPE, LLDPE, LDPE, HDPE, PP, thiab recycled polyolefins.
