Vim li cas Synthetic Turf Cov Tuam Txhab Tsiv Tawm ntawm PFAS?
Per- thiab polyfluoroalkyl tshuaj (PFAS) yog cov khoom siv hluavtaws feem ntau siv hauv ntau qhov kev lag luam, suav nrog cov khoom siv hluavtaws, rau lawv cov dej-repellent, stain-resistant, thiab ruaj khov zog. Txawm li cas los xij, kev siv PFAS hauv cov khoom siv hluavtaws tau ua rau muaj kev txhawj xeeb loj, ua rau muaj kev hloov pauv mus rau PFAS-dawb lwm txoj kev. Hauv qab no yog cov laj thawj tseem ceeb ntawm cov tuam txhab lag luam zam kev zam PFAS thiab kev tshawb nrhiav tsis tu ncua rau PFAS-dawb txheej txheem kev ua tau zoo ntxiv (PPAs) thiab lwm yam tsis muaj fluorine:
1. Kev phom sij rau kev noj qab haus huv
Qhov teeb meem:PFAS, feem ntau hu ua "tshuaj lom neeg mus ib txhis" vim lawv cov ntawv cog lus carbon-fluorine tsis tu ncua, txuas rau kev pheej hmoo mob hnyav, suav nrog mob qog noj ntshav, tiv thaiv kab mob, thiab teeb meem kev loj hlob. Hauv cov turf hluavtaws, PFAS hauv cov ntaub pua plag, cov hniav, los yog cov khoom ntim tuaj yeem noj lossis nqus tau, tshwj xeeb tshaj yog los ntawm cov menyuam yaus lossis cov neeg ncaws pob ntawm cov chaw degraded uas cov plua plav thiab cov khoom tawm.
Cov pov thawj:Kev tshawb fawb, xws li 2022 Environmental Science & Technology tsab ntawv ceeb toom, pom pom PFAS qib hauv cov kua qaub ntawm cov neeg ncaws pob uas siv cov khoom siv hluavtaws.
Kev lag luam teb:Cov tuam txhab loj tam sim no tseem ceeb rau PFAS-dawb turf, tshwj xeeb tshaj yog rau cov tsev kawm ntawv thiab chaw ua si, txhawm rau txo kev lav phib xaub thiab ua raws li cov cai ntawm kev saib xyuas.
2. Kev cuam tshuam ib puag ncig: Tiv thaiv kev kis kab mob mus ntev
Qhov teeb meem: PFAS tsis degrade ib txwm muaj thiab khaws cia hauv ecosystems. Turf field runoff tau pom tias muaj paug cov khoom siv dej.
Case Study:Ib xyoo 2021 Kev Tshawb Fawb Kev Tshawb Fawb Txog Dej tau tshawb pom PFAS hauv 78% ntawm cov qauv dej hauv av ze ze ntawm cov khoom siv turf.
Regulatory Action:Kalifonias Txoj Cai Kev Haus Dej Nyab Xeeb thiab Kev Ua Phem Txhaum Cai (Txoj Cai 65) teev PFAS ua cov tshuaj tswj hwm.
EU's Registration, Evaluation, Tso Cai thiab Kev Txwv Cov Tshuaj (REACH) lub moj khaum yog phasing tawm PFAS hauv cov neeg siv khoom.
Kev daws:PFAS-dawb turf systems tshem tawm cov fluorinated coatings thiab ua ke nrog cov infills ruaj khov (xws li, cork, txiv maj phaub husk) kom txo tau ib puag ncig persistence.
3. Kev Tswj Xyuas Kev Ruaj Ntseg: Ua Raws Li Kev Tsav Tsheb Hloov
Cov kev cai thoob ntiaj teb:
Teb Chaws Asmeskas: Cov xeev xws li California (Assembly Bill No. 1423, siv tau rau xyoo 2024) thiab New York yuam kom cov qib PFAS tsis tuaj yeem kuaj pom hauv cov haujlwm pej xeem.
EU: Kev txwv PFAS raws li REACH tuaj yeem siv los ntawm 2025.
Test Standards:Cov neeg tsim khoom siv EPA Method 533 (rau cov qauv kuaj) lossis ASTM D7968 kom lees paub qhov xwm txheej tsis pub PFAS.
Kev hloov kho kev lag luam:Cov tuam txhab xws li TenCate Grass thiab SYNLawn hloov kho cov khoom siv hluavtaws kom ua tau raws li cov qauv no, nrog rau kev pov thawj thib peb.
Vim li cas PFAS pom hauv cov nyom dag?
Txij li thaum nruab nrab xyoo pua 20th, kev lag luam tau nce siv fluorinated txheej txheem kev ua tau zoo ntxiv (PPAs) raws li tus qauv hauv plastics thiab textile manufacturing. Cov additives, uas suav nrog fluoropolymers zoo li polytetrafluoroethylene derivatives thiab fluoroelastomers, feature carbon-fluorine (CF) bonds uas muaj feem xyuam nrog per- thiab polyfluoroalkyl tshuaj (PFAS).
Keeb kwm, fluorinated PPAs, 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 cov nyom dag. Lawv feem ntau siv rau hauv cov txheej txheem xws li hniav extrusion thiab rov qab txheej. Cov additives no tsis tsuas yog txhim kho cov kev ua tau zoo ntawm polyethylene thiab polypropylene extrusion tab sis kuj txhim khu cov nto tiav, durability, thiab dej tsis kam ntawm turf. Los ntawm kev txo qis kev tuag thiab tiv thaiv cov pob txha tawg, lawv pab txhawb kev tsim cov fibers zoo li qub, ua kom lub neej ntev ntawm cov khoom, thiab txo cov nqi tsim khoom. Cov kev nce qib no tau ua qhov tseem ceeb hauv kev ua kom tau raws li qhov kev thov loj hlob rau kev ua haujlwm siab, kev tu vaj tse qis.
SILIKE cov kev daws teeb meem tsis muaj fluorine
Txhawm rau daws cov teeb meem cuam tshuam nrog PFAS, SILIKE tau pib SILIMER series. Cov khoom lag luam tshiab no suav nrog ntau yam ntawm 100% PFAS dawb huv thiab tsis muaj fluorine-free polymer processing additives (PPAs), nrog rau PFAS-dawb thiab fluorine-dawb PPA masterbatches. Tsim los ntawm cov organic hloov pauv polysiloxane, cov kev xaiv no tsis tsuas yog txhim kho cov roj nplua nyeem thiab cov khoom siv saum npoo av, tab sis kuj txhawb kev nyab xeeb, kev ruaj ntseg dua los ntawm kev tshem tawm kev siv cov tshuaj fluorine teeb meem. Los ntawm kev xaiv SLIKE SILIMER seriesPFAS-Dawb PPAs, koj tuaj yeem ua rau muaj kev noj qab haus huv ib puag ncig thaum tau txais txiaj ntsig los ntawm kev ua tau zoo.
Cov txiaj ntsig ntawm SILIMER series PFAS-Dawb PPAs:
- Siv tau zoo nyob hauv cov pob txha tawg (sharkskin)
