Vim li cas cov chaw tsim khoom siv nyom hluavtaws thiaj li tsiv tawm ntawm PFAS？
Cov tshuaj Per- thiab polyfluoroalkyl (PFAS) yog cov tshuaj siv ua vaj tse uas siv ntau hauv ntau yam lag luam, suav nrog cov nyom ua vaj tse, rau lawv cov khoom uas tsis muaj dej, tsis yooj yim ploj xim, thiab ruaj khov. Txawm li cas los xij, kev siv PFAS hauv cov nyom ua vaj tse tau ua rau muaj kev txhawj xeeb ntau, ua rau muaj kev hloov mus rau lwm cov khoom siv uas tsis muaj PFAS. Hauv qab no yog cov laj thawj tseem ceeb uas cov tuam txhab tsim khoom zam PFAS thiab kev nrhiav cov khoom siv ntxiv rau kev ua haujlwm tsis muaj PFAS (PPAs) thiab lwm cov khoom siv uas tsis muaj fluorine:
1. Kev Pheej Hmoo Txog Kev Noj Qab Haus Huv
Qhov teeb meem:PFAS, feem ntau hu ua "cov tshuaj lom neeg mus ib txhis" vim lawv cov pa roj carbon-fluorine sib txuas, muaj feem cuam tshuam nrog kev pheej hmoo loj rau kev noj qab haus huv, suav nrog mob qog noj ntshav, kev cuam tshuam ntawm lub cev tiv thaiv kab mob, thiab teeb meem kev loj hlob. Hauv cov nyom ua los ntawm cov khoom siv dag, PFAS hauv cov ntaub pua plag, cov hniav, lossis cov khoom siv infill tuaj yeem noj lossis nqus tau, tshwj xeeb tshaj yog cov menyuam yaus lossis cov neeg ncaws pob ntawm cov chaw ua si uas puas tsuaj qhov twg cov hmoov av thiab cov khoom me me raug tso tawm.
Cov pov thawj:Cov kev tshawb fawb, xws li daim ntawv qhia txog Kev Tshawb Fawb Txog Ib puag ncig thiab Kev Siv Tshuab xyoo 2022, pom cov qib PFAS uas pom tau hauv cov qauv qaub ncaug ntawm cov neeg ncaws pob siv cov teb ua los ntawm cov khoom siv hluavtaws.
Cov Lus Teb Los Ntawm Kev Lag Luam:Cov chaw tsim khoom loj tam sim no muab qhov tseem ceeb rau cov nyom uas tsis muaj PFAS, tshwj xeeb tshaj yog rau cov tsev kawm ntawv thiab cov chaw ua si, kom txo qhov kev lav phib xaub thiab ua raws li cov ntsiab cai ntawm kev saib xyuas.
2. Kev Cuam Tshuam Rau Ib Puag Ncig: Tiv Thaiv Kev Ua Phem Mus Ntev
Qhov teeb meemPFAS tsis lwj mus rau hauv av thiab sib sau ua ke hauv cov ecosystem. Cov dej ntws los ntawm cov nyom tau pom tias ua rau cov dej tsis huv.
Kev Kawm Txog Cov Ntaub Ntawv:Ib txoj kev tshawb fawb xyoo 2021 ntawm Lub Koom Haum Tshawb Fawb Txog Dej tau pom PFAS hauv 78% ntawm cov qauv dej hauv av ze ntawm cov chaw tsim cov nyom dag.
Kev Cai Lij Choj:Txoj Cai Lij Choj Txog Dej Haus thiab Kev Siv Tshuaj Lom ntawm California (Proposition 65) teev cov PFAS ua ib yam tshuaj uas raug tswj.
Lub EU txoj cai Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) tab tom tshem tawm PFAS hauv cov khoom siv.
Kev daws teeb meem:Cov txheej txheem turf uas tsis muaj PFAS tshem tawm cov txheej fluorinated thiab ua ke nrog cov khoom siv ruaj khov (piv txwv li, cork, txiv maj phaub husk) kom txo qhov kev nyob ib puag ncig.
3. Kev Tswj Xyuas Kev Cai: Kev Ua Raws Cai Tsav Kev Hloov Pauv
Cov Cai Thoob Ntiaj Teb:
Tebchaws Meskas: Cov xeev zoo li California (Assembly Bill No. 1423, siv tau xyoo 2024) thiab New York yuam kom cov theem PFAS uas tsis pom hauv cov haujlwm pej xeem.
EU: Cov kev txwv PFAS raws li REACH yuav siv tau los ntawm xyoo 2025.
Cov Qauv Kev Xeem:Cov chaw tsim khoom siv EPA Txoj Kev 533 (rau cov qauv khoom khov) lossis ASTM D7968 los ua pov thawj tias tsis muaj PFAS.
Kev Hloov Kho Kev Lag Luam:Cov tuam txhab xws li TenCate Grass thiab SYNLawn hloov kho cov khoom siv Synthetic Turf kom ua tau raws li cov qauv no, nrog rau kev txheeb xyuas los ntawm cov neeg thib peb.
Vim li cas PFAS thiaj pom muaj nyob rau hauv cov nyom dag?
Txij li thaum nruab nrab xyoo pua 20th, cov lag luam tau siv cov tshuaj ntxiv rau kev ua haujlwm ntawm cov txheej txheem fluorinated (PPAs) ua tus qauv hauv kev tsim cov yas thiab cov ntaub. Cov tshuaj ntxiv no, uas suav nrog fluoropolymers xws li polytetrafluoroethylene derivatives thiab fluoroelastomers, muaj cov pa roj carbon-fluorine (CF) uas cuam tshuam nrog cov tshuaj per- thiab polyfluoroalkyl (PFAS).
Keeb kwm, cov tshuaj PPA uas muaj fluorinated, tshwj xeeb tshaj yog los ntawm cov tuam txhab lag luam xws li 3M, tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev tsim cov nyom dag. Lawv feem ntau siv rau hauv cov txheej txheem xws li kev rho hniav thiab cov txheej txheem thaub qab. Cov tshuaj ntxiv no tsis yog tsuas yog txhim kho kev ua haujlwm ntawm polyethylene thiab polypropylene extrusion tab sis kuj txhim kho qhov tiav ntawm qhov chaw, kev ruaj khov, thiab kev tiv thaiv dej ntawm cov nyom. Los ntawm kev txo qis kev tsim cov pwm thiab tiv thaiv kev tawg ntawm cov yaj, lawv pab txhawb kev tsim cov fibers sib xws, txuas ntxiv lub neej ntev ntawm cov khoom, thiab txo cov nqi tsim khoom. Cov kev nce qib no tau ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li qhov kev thov loj hlob rau kev ua haujlwm siab, kev daws teeb meem nyom uas tsis tas yuav saib xyuas.
SILIKE cov kev daws teeb meem uas tsis muaj fluorine
Txhawm rau daws cov teeb meem cuam tshuam nrog PFAS, SILIKE tau tshaj tawm SILIMER series. Cov kab khoom tshiab no suav nrog ntau yam ntawm 100% ntshiab PFAS-dawb thiab fluorine-free polymer processing additives (PPAs), nrog rau PFAS-dawb thiab fluorine-free PPA masterbatches. Tsim los ntawm cov organically hloov kho polysiloxane, cov kev xaiv no tsis yog tsuas yog txhim kho lubrication thiab cov khoom nto tab sis kuj txhawb nqa txoj hauv kev nyab xeeb dua, ruaj khov dua los ntawm kev tshem tawm kev siv cov tshuaj fluorine uas ua rau muaj kev phom sij. Los ntawm kev xaiv SLIKE SILIMER seriesPFAS-Free PPAs, koj tuaj yeem pab txhawb rau ib puag ncig noj qab haus huv thaum tau txais txiaj ntsig los ntawm kev ua tau zoo dua.

- Txhim kho tag nrho cov khoom ua tiav
- Txo qhov tsis zoo ntawm qhov chaw, ua rau qhov chaw tiav zoo dua thaum lub sijhawm extrusion ntawm polyethylene lossis polypropylene turf blades.
Txhim Kho Kev Ua Haujlwm Polymer Zoo:Cov Kev daws teeb meem PPA rau kev tsim khoom
SILIKE's SILIMER series PFAS-Free PPAs muaj txiaj ntsig zoo heev rau ntau yam kev lag luam. Lawv yog qhov tshwj xeeb tshaj yog rau cov ntawv thov hauv cov nyom dag (cov nyom dag), cov masterbatch ua haujlwm, cov yas zaj duab xis, tshuab molding, extrusion, fibers, raj, ntawv, thiab cables. Cov kev daws teeb meem Polymer Processing Aids no tau tsim los ua kom tau raws li ntau yam kev xav tau thaum tswj hwm cov qauv kev ua tau zoo.
Ntsib kev nyuaj siab ntawm kev cai lij choj thiab kev ua lag luamtshem tawm PFAS thiab cov tshuaj ntxiv fluorines los ntawm lawv cov txheej txheem polymer? Rau cov lag luam cog lus rau kev tsim khoom uas zoo rau ib puag ncig, SILIKE muab kev daws teeb meem ua tau zoo, tsis muaj PFAS - zoo meej rau koj cov kev xav tau.
