Pfoa \/ s foam vs fluorine-dawb foams
Pfoa \/ s-based foams (piav qhia tshwj xeeb ntawm cov yeeb yaj kiab uas tau siv hluav taws xob nrawm, roj tsis kam, thiab kav ntev hauv kev xav tau kev lag luam \/ tub rog; Txawm li cas los xij, cov lej PFAS no yog ib puag ncig ua rau ib puag ncig, thiab kev txwv tsis pub muaj mob qog noj ntshav (piv txwv li EPA theem-outs) thiab kev txwv tsis pub muaj txiaj ntsig zoo. Nyob rau hauv kev sib piv, fluorine dawb niaj hnub (F3) ua haujlwm eco-tsim kev nyab xeeb, thiab kev coj ua qeeb qeeb, xav tau cov khoom siv qeeb qeeb lossis kho vajtse hloov kho; Thaum F3 foams tam sim no yuav tsum tau nyob rau hauv cov chaw tsim hluav taws xob hauv ecologically (piv txwv li, tshav dav hlau pfas ua npuas dej ib ntus
1. Dab tsi yog PFOA \/ S Ua Npuas Ncauj?
Pfoa \/ s (perfluorooctantantantantantantantantantoic) Ua npuas ncauj) Ua npuas ncauj muaj cov lus qhia hluavtaws tsis huv sai sai (" Zoo heev tab sis ib puag ncig pheej yig, nws poses bioaccumulation thiab kev pheej hmoo muaj kev noj qab haus huv.
2. Dab tsi yog fluorine-dawb ua npuas dej (F3)?
Fluorine-dawb ua npuas dej (F3) siv hydrocarbon surfactants es tsis txhob pfas. Nws tshem tawm cov hluav taws kub los ntawm kev sib khi roj thiab txias, cuam tshuam ib puag ncig \/ kev noj qab haus huv ib puag ncig. Tsawg pheej yig dua PFOA \/ S tab sis yuav xav tau cov ntawv thov siab dua.
3. Yuav ua li cas xaiv ntawm lawv?
| Yam tseem ceeb | Pfoa \/ s ua npuas ncauj | Fluorine-dawb ua npuas ncauj (F3) |
|---|---|---|
| Hauj tes | Tshaj teb kom nrawm | Zoo, tab sis qeeb qeeb ntawm cov kuab tshuaj polar |
| Cuam tshuam ib puag ncig | Siab heev (pfas qias neeg) | Biodegradable, eco-phooj ywg |
| Kev cai | Txwv \/ txwv nyob rau ntau thaj tsam | Ua raws li ntiaj teb cov kab lis (piv txwv li, EU, Asmeskas xeev) |
| Tus nqi | Qis dua upfront tus nqi | Siab dua qub tus nqi, qis dua lub luag haujlwm ntev |
* Xaiv F3 rau eco-rhiab chaw; Pfoa \/ s tsuas yog qhov twg cov kev cai uas cia thiab kev pheej hmoo xav tau kev ua tau zoo heev. *
4. Qhov twg yuav siv txhua tus?
Pfoa \/ s ua npuas ncauj:
Cov hauv cov cheeb tsam hauv cov cheeb tsam muaj cov cheeb tsam (roj ua kom zoo dua, tshuaj lom neeg)Qhov twg cov kev cai tso cai.
Cov tub rog muaj kev pheej hmoo \/ aviation cov chaw uas xav tau hluav taws kub ntau tshaj plaws.
Fluorine-dawb ua npuas ncauj (F3):
Tshav dav hlau nyob ze cov dej, hauv nroog hluav taws kub brigades, thaj chaw eco rhiab (ports, hav zoov).
Cov kev teeb tsa tshiab nyob rau hauv Pfas bans (piv txwv li, EU, California).
5. Yuav ua li cas siv lawv?
Daim ntawv thov:
Ob qho tib si siv cov npe ua npuas ncauj (3-6% sib piv) nrog tsom kwm \/ sprinklers.
Qhov sib txawv:
Pfoa \/ s: Cov kev ua tau zoo nyob thoob plaws hauv cov roj (hydrocarbons \/ polar solvents).
F3: Tej zaum yuav xav tau daim ntawv thov siab dua (ntau dua lossis sib npaug raws li 6%) rau polar solvents (piv txwv li ethanol).
Cia \/ Tuav:
Pfoa \/ s yuav tsum tau PFAs muaj cov txheej txheem; F3 tsis muaj kev txwv kev txwv tshwj xeeb.
Ua cov tuam txhab ua rau cov khoom tua hluav taws, ua ntej muaj ntau yam xws li hluav taws kub thiab cov tshuab ua npuas dej, hluav taws xob tshuab hluav taws, tua hluav taws truck accessories.etc.
