Lub hauv paus rau phau ntawv
Tawm tsam lub nraub qaum ntawm nce ntiaj teb ib puag ncig ib puag ncig, rov ua plastics tau dhau los ua kev daws teeb meem tseem ceeb rau kev txhim kho kom ruaj khov. Ntawm lawv, RPET (rov ua dua polyethylene terepthalate) cov chips yog raphaping cov khoom siv muab khoom siv ntau yam li cov ntawv sau, thiab cov tsheb sib txuas nrog lawv cov yam ntxwv. Cov khoom dawb zoo tib yam li cov khoom dawb yog qhov tseeb ntawm cov ntawv tseem ceeb rau cov khib nyiab yas rau rov qab nws lub neej tshiab. Lawv hloov los ntawm cov dej haus hauv dej haus kom qhuav rau hauv kev ua haujlwm siab, ntim cov khoom lag luam, thiab cov lag luam hauv tsheb ntawm lub ntiaj teb cov kev lag luam ncig.
Kab lus no yuav tshawb txog cov lus txhais, cov txheej txheem thov cov khoom lag luam thiab kev lag luam hauv cov phiaj xwm kev nyuaj siab, thiab kev lag luam cov kev sib tw thiab kev tsim kho uas yuav ntsib rau yav tom ntej.
Dab tsi yog rpet nti?
2.1 Kev Txhais Lus thiab Qhov Chaw Ntawm RPET
RPET (rov ua dua polyethylene terephthalate)yog cov khoom siv rov ua dua tshiab los ntawm kev rov ua kom cov roj av uas muaj pov tseg (xws li cov roj mineral cov raj dej, lub fowerage fwj, thiab lwm yam). Piv nrog cov tsiaj nkauj xwb, cov txheej txheem ntau lawm ntawm RPET heev txo qis ntawm cov roj av cov pa hluav taws xob thiab txo cov roj carbon emissions.
2.2 cov txheej txheem ntau lawm ntawm rpet chips
Kev tsim cov khoom siv rpet muaj ntau kauj ruam ntau cov kauj ruam los xyuas kom meej meej cov khoom siv thiab muaj cov khoom siv ua rov qab:
Kev sau thiab faib tawm: Cov khib nyiab cov tsiaj ntim tau sau los ntawm kev rov ua dua tshiab thiab faib cov xim thiab cov khoom siv.
Kev ntxuav tu thiab tua kab: Tshem cov ntawv cim, seem thiab cov paug tsis huv, thiab ua kom muaj kev tsis huv.
Kev sib tsoo thiab melting: Cov tsiaj ntxuav tau huv yog txiav ua tej daim thiab ces yaj los tshem tawm impurities.
Extrusion Granulation: Molten Cov Khoom Siv Tsiaj yog extruded thiab txiav mus rau hauv cov khoom siv hluav taws xob sib xyaw (tej zaum).
Qhov system kaw-Visp uas kaw lawm tsis tsuas yog txhim kho tus nqi ntawm cov plastics, tab sis kuj tseem ceeb txo cov pa phem ib puag ncig.
Qhov tseem ceeb ntawm RPET CHIPS
3.1 cov txiaj ntsig ib puag ncig
Txo cov pa roj carbon emissions: muab piv nrog nkauj xwb tus tsiaj, kev tsim cov rpet tuaj yeem txo cov hneev taw ntawm cov pa roj carpin li 75%.
Txo kev siv zog txuag hluav taws xob: kev ua cov kev siv hluav taws xob ntawm cov tsiaj uas rov siv dua yog 50% qis dua li ntawm cov tsiaj nkauj xwb.
Alleviate yas paug: txo cov khib nyiab yas hauv cov chaw pov tseg thiab dej hiav txwv, thiab pab txhawb rau cov hom phiaj yas thoob ntiaj teb.
3.2 Cov Kev Pab Nyiaj Txiag
Txo cov nqi ntau lawm: Reccled plastics muaj ntau tus nqi ua kom zoo dua nkauj xwb plastics, tshwj xeeb tshaj yog thaum cov roj cov nqi fluction.
Ntsib cov neeg xav tau: Raws li cov neeg nyiam ua lag luam rau cov khoom lag luam kom muaj cov khoom lag luam nce ntxiv, cov tswv lag luam hom lag luam rau rpet tseem loj hlob ntxiv.
Daim ntawv thov cov chaw ntawm RPET CHIPS
4.1 textile thiab khaub ncaws kev lag luam
RPET cov lus yog yaj-spun rau hauv cov khoom siv polyester (RPIs)
4.2 Kev Lag Luam Ntim
Rpet tuaj yeem yog kho dua rau hauv cov raj ntim khoom lag luam-ntim khoom, cov ntaub ntawv kom zoo nkauj, thiab lwm yam. Cov tuam txhab xws li Coca-Cola thiab Unilever tau cog lus kom nce cov feem ntawm rpet hauv kev ntim khoom kom txo cov kuab paug ntxiv.
4.3 tsheb thiab tsim kev lag luam
Hauv cov tsheb tsim khoom, rpet yog siv los tsim cov rooj zaum, cov suab rwb thaiv tsev cov ntaub ntawv thiab cov khoom sab hauv. Kev tsim kho kev tsim kho siv nws lub teeb thiab cov khoom siv ruaj khov los ua cov panels thiab ntaub pua plag.
Tuam Tshoj lub luag haujlwm tseem ceeb hauv kev lag luam RPET
Tuam Tshoj yog ib lub teb chaws loj tshaj plaws, kev sib xyaw ntau lab ntawm tons ntawm cov hwj yas pov tseg txhua xyoo. Hauv cov tuam txhab tsis ntev los no, Suav cov tuam txhab tau txhim kho cov cuab yeej thev naus laus zis (xws li FDA thiab EU cov qauv kev lag luam hauv Tebchaws Europe thiab Tebchaws Asmeskas. Ib qho ntxiv, kev cai txhawb txoj cai (xws li "kev txiav txim siab yas") tau ntxiv kev txhim kho kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam RPET.
Cov kev sib tw ntsib RPET kev lag luam
Txawm hais tias nws cov lus cog tseg, kev lag luam RPET tseem ntsib cov teeb meem hauv qab no:
Kev Ua Haujlwm Tsis Txaus Siab: Qee thaj chaw tseem tsis muaj cov khib nyiab ua tau zoo thiab rov ua dua tshiab.
Cov Qauv-Tus Qauv-Tus Qauv Kawm Qib: Cov ntawv pov thawj yuav tsum sib txawv ntawm lub tebchaws, cuam tshuam kev lag luam nce qib.
Cov neeg tau txais kev paub txaus siab tsis txaus: Coob tus neeg tseem tsis tuaj yeem paub qhov txawv ntawm RPET thiab dog dig tsiaj, cuam tshuam kev yuav cov kev txiav txim siab.
Kev tsim kho yav tom ntej
Kev siv thev naus laus zis: Cov thev naus laus zis siv tshuaj lom zem yuav tsum txhim kho qhov kev coj dawb huv thiab kev siv tau ntawm RPET.
Txoj Cai Txhawb Txoj Cai: Cov tseemfwv yuav qhia cov kev cai txhawb nqa los txhawb txoj kev loj hlob ntawm RPet kev thov.
Hom Kev Cog Lus: Ntau cov tuam txhab yuav koom nrog "cov khoom siv ua rov qab ua dua" los txhawb kev ua lag luam kev lag luam.
Tag
RPET CHIPS tsis yog tsuas yog tus xa rov qab rau cov khoom siv roj hmab yas rau cov khib nyiab yas, tab sis kuj yog cov khoom tseem ceeb rau kev txhawb nqa cov kev lag luam ncig. Cov thev naus laus zis, cov cai siv thiab kev lag luam lag luam, tsheb, thiab lwm thaj teb thiab pab ua tiav cov hom phiaj txhim kho thoob ntiaj teb. Nyob rau yav tom ntej, ntxiv dag zog rau kev tsim kho cov tshuab ua rov qab, txhim kho cov neeg siv khoom siv thiab kev txhawb nqa kev lag luam kev lag luam yuav yog qhov tseem ceeb ntawm kev lag luam RPET.
