PET (Polyethylene Terephthalate) yog cov khoom siv yas siv dav hauv kev lag luam ntim khoom. Nrog nce thoob ntiaj teb kev paub txog ib puag ncig, kev lag luam yav tom ntej thiab kev cuam tshuam ib puag ncig ntawm PET plastics tau txais kev saib xyuas ntau.
Yav dhau los ntawm PET Khoom
Nyob rau hauv nruab nrab-xyoo pua 20th, qhov zoo tshaj plaws PET polymer, Polyethylene Terephthalate, tau tsim thawj zaug. Cov neeg tsim khoom tau nrhiav cov khoom siv uas tuaj yeem siv rau ntau yam kev lag luam. Nws lub teeb yuag, pob tshab, thiab muaj zog ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv dav. Thaum xub thawj, PET tau siv feem ntau hauv kev lag luam textile ua cov khoom siv raw rau hluavtaws fibers (polyester). Thaum lub sij hawm, daim ntawv thov ntawm PET maj mam nthuav mus rau hauv lub ntim sector, tshwj xeeb tshaj yog nyob rau hauvlub raj mis dej haus thiab ntim khoom noj.
Qhov tshwm sim ntawm PET lub raj mis hauv xyoo 1970 tau pom tias nws tau nce hauv kev lag luam ntim khoom.PET fwj thiabPET khob haus, nrog rau lawv lub teeb yuag, siab zog, thiab pob tshab zoo, hloov cov iav fwj thiab cov kaus poom hlau sai sai, dhau los ua cov khoom nyiam rau ntim dej haus. Nrog kev nce qib hauv cov thev naus laus zis ntau lawm, tus nqi ntawm cov khoom siv PET maj mam txo qis, ntxiv kev txhawb nqa nws cov ntawv thov thoob plaws ntiaj teb.
Qhov nce thiab qhov zoo ntawm PET
Kev nce nrawm ntawm cov khoom siv PET yog vim nws qhov zoo heev. Ua ntej, PET muaj cov khoom zoo ntawm lub cev, xws li lub zog siab, hnav tsis kam, thiab tshuaj tiv thaiv corrosion, ua rau nws ua tau zoo hauv kev ntim khoom thiab kev lag luam. Qhov thib ob, cov khoom siv PET muaj qhov pom tseeb zoo thiab ci ntsa iab, muab qhov pom kev zoo hauv cov ntawv thov xws li lub raj mis dej haus thiab cov thawv ntim khoom noj.
Tsis tas li ntawd, kev rov ua dua ntawm cov khoom siv PET kuj yog qhov zoo dua. PET yas tuaj yeem siv tau thiab rov siv dua los ntawm lub cev lossis tshuaj siv los tsim cov ntaub ntawv PET (rPET) rov siv dua. rPET cov ntaub ntawv tuaj yeem tsis tsuas yog siv los tsim lub raj mis PET nkaus xwb tab sis kuj tseem siv rau hauv textiles, kev tsim kho, thiab lwm yam kev lag luam, txo qhov cuam tshuam ib puag ncig ntawm cov pov tseg yas.
Environmental Impact
Txawm hais tias muaj ntau qhov zoo ntawm cov ntaub ntawv PET, lawv cov kev cuam tshuam ib puag ncig tsis tuaj yeem tsis quav ntsej. Cov txheej txheem tsim khoom ntawm PET plastics siv ntau cov peev txheej roj av thiab tsim qee cov pa roj carbon monoxide emissions. Tsis tas li ntawd, tus nqi degradation ntawm PET plastics nyob rau hauv ib puag ncig ntuj yog qeeb heev, feem ntau yuav tsum tau ntau pua xyoo, ua rau lawv yog ib qho tseem ceeb ntawm cov pa phem.
Txawm li cas los xij, piv rau lwm hom yas, kev rov ua dua ntawm PET muab qhov zoo dua rau kev tiv thaiv ib puag ncig. Cov ntaub ntawv pov thawj qhia tau hais tias kwv yees li 26% ntawm PET plastics tau rov ua dua tshiab thoob ntiaj teb, feem ntau ntau dua li lwm cov ntaub ntawv yas. Los ntawm kev nce tus nqi rov ua dua ntawm PET plastics, lawv qhov kev cuam tshuam tsis zoo rau ib puag ncig tuaj yeem txo tau zoo.

Tsis tas li ntawd, tus nqi degradation ntawm PET plastics nyob rau hauv ib puag ncig ntuj yog qeeb heev, feem ntau yuav tsum tau ntau pua xyoo, ua rau lawv yog ib qho tseem ceeb ntawm cov pa phem.
Txawm li cas los xij, piv rau lwm hom yas, kev rov ua dua ntawm PET muab qhov zoo dua rau kev tiv thaiv ib puag ncig. Cov ntaub ntawv pov thawj qhia tau hais tias kwv yees li 26% ntawm PET plastics tau rov ua dua tshiab thoob ntiaj teb, feem ntau ntau dua li lwm cov ntaub ntawv yas. Los ntawm kev nce tus nqi rov ua dua ntawm PET plastics, lawv qhov kev cuam tshuam tsis zoo rau ib puag ncig tuaj yeem txo tau zoo.
Kev cuam tshuam ib puag ncig ntawm PET Disposable Cups
Raws li cov khoom ntim khoom noj thiab dej haus, ib puag ncig cuam tshuam ntawmPET cov khob pov tsegkuj yog ib qho kev txhawj xeeb tseem ceeb. Txawm hais tias PET khob dej haus thiab PET txiv hmab txiv ntoo tshuaj yej khob muaj qhov zoo xws li lub teeb yuag, pob tshab, thiab zoo nkauj, lawv siv ntau thiab kev pov tseg tsis zoo tuaj yeem ua rau muaj teeb meem loj rau ib puag ncig.
Tus nqi degradation ntawm PET cov khob pov tseg hauv ib puag ncig ntuj yog qeeb heev. Yog tias tsis rov siv dua, lawv tuaj yeem tsim kev puas tsuaj mus ntev rau ecosystems. Tsis tas li ntawd, PET cov khob pov tseg yuav ua rau muaj kev phom sij rau kev noj qab haus huv thaum siv, xws li tso tawm cov khoom tsis zoo nyob rau hauv qhov kub thiab txias. Yog li ntawd, kev txhawb nqa kev rov ua dua tshiab thiab rov siv dua ntawm PET cov khob pov tseg kom txo lawv cov kev cuam tshuam ib puag ncig yog qhov teeb meem ceev uas yuav tsum tau daws.
Lwm yam kev siv ntawm PET Plastics
Sib nrug los ntawm lub raj mis dej haus thiab ntim khoom noj, PET plastics tau siv dav hauv lwm qhov chaw. Hauv kev lag luam textile, PET, raws li cov khoom siv tseem ceeb rau polyester fibers, yog siv dav hauv kev tsim khaub ncaws thiab tsev textiles. Hauv kev lag luam, PET plastics, vim lawv lub cev zoo heev, yog siv los tsim cov khoom siv hluav taws xob thiab cov khoom siv tsheb.
Tsis tas li ntawd, cov ntaub ntawv PET muaj qee yam kev siv hauv kev kho mob thiab kev tsim kho. Piv txwv li, PET tuaj yeem siv los tsim cov khoom siv kho mob thiab ntim tshuaj vim nws cov biocompatibility zoo thiab kev nyab xeeb. Hauv kev tsim kho kev lag luam, cov ntaub ntawv PET tuaj yeem siv los tsim cov ntaub ntawv rwb thaiv tsev thiab cov ntaub ntawv zoo nkauj, paub txog lawv cov kav ntev thiab ib puag ncig tus phooj ywg.
Cov lus nug nquag nug txogPET khob
1. PET khob puas muaj kev nyab xeeb?
PET khob muaj kev nyab xeeb raws li kev siv ib txwm siv thiab ua raws li cov qauv tsim nyog rau cov ntaub ntawv tiv tauj cov khoom noj. Txawm li cas los xij, lawv tuaj yeem tso cov kab mob ntawm cov khoom tsis zoo nyob rau hauv qhov kub thiab txias, yog li nws raug nquahu kom tsis txhob siv PET khob hauv qhov chaw kub.
2. Puas yog PET khob rov ua dua?
PET khob yog recyclable thiab tuaj yeem ua tiav rau hauv cov ntaub ntawv PET rov ua dua los ntawm txoj kev siv lub cev lossis tshuaj. Txawm li cas los xij, tus nqi rov ua dua tshiab tsuas yog txwv los ntawm kev ua tiav ntawm cov khoom siv rov ua dua tshiab thiab kev paub txog cov neeg siv khoom.
3. Dab tsi yog qhov cuam tshuam ib puag ncig ntawm PET khob?
Tus nqi degradation ntawm PET khob hauv ib puag ncig ntuj yog qeeb, uas yuav ua rau muaj kev cuam tshuam ntev rau ecosystems. Kev nce tus nqi rov ua dua tshiab thiab txhawb nqa kev siv cov khoom siv PET rov qab yog txoj hauv kev zoo los txo lawv cov kev cuam tshuam ib puag ncig.
Lub neej yav tom ntej ntawm cov khoom siv PET
Nrog nce thoob ntiaj teb kev paub txog ib puag ncig thiab kev nce qib thev naus laus zis txuas ntxiv, cov khoom siv PET yuav ntsib txoj hauv kev txhim kho tshiab thiab cov teeb meem yav tom ntej. Ntawm qhov tod tes, nrog kev ua tiav tas mus li ntawm kev siv thev naus laus zis, cov khoom siv rov ua dua tshiab ntawm PET yuav tsum txhim kho ntxiv, yog li txo lawv cov kev cuam tshuam tsis zoo. Ntawm qhov tod tes, kev tshawb fawb thiab kev siv cov ntaub ntawv bio-based PET (Bio-PET) kuj tau nce qib, muab cov lus qhia tshiab rau kev txhim kho cov ntaub ntawv PET.
Nyob rau yav tom ntej,PET khob dej haus, PET txiv hmab txiv ntoo tshuaj yej khob, thiab PET pov tseg khob yuav xyuam xim rau ib puag ncig kev ua tau zoo thiab kev nyab xeeb kev noj qab haus huv, txhawb kev txhim kho kom ruaj khov. Raws li lub ntiaj teb ntsuab kev loj hlob keeb kwm yav dhau, yav tom ntej ntawm cov ntaub ntawv PET yog tag nrho ntawm kev cia siab thiab muaj peev xwm. Los ntawm kev tsim kho tshiab thiab kev siv zog tas mus li, PET plastics yuav tsum pom qhov sib npaug ntawm kev ua kom tau raws li kev xav tau ntawm kev lag luam yav tom ntej thiab kev tiv thaiv ib puag ncig, dhau los ua qauv rau cov ntim ntsuab.
Txoj kev loj hlob ntawm PET plastics yuav tsum tsom tsis tsuas yog kev lag luam xav tau tab sis kuj tseem cuam tshuam rau ib puag ncig. Los ntawm kev nce tus nqi rov ua dua tshiab, txhawb nqa kev siv cov ntaub ntawv PET rov ua dua tshiab, thiab ua kom muaj kev tshawb fawb thiab kev loj hlob ntawm bio-based PET, PET plastics yuav tsum pom qhov sib npaug tshiab ntawm kev xav tau ntawm kev lag luam yav tom ntej thiab kev tiv thaiv ib puag ncig, ua tau raws li qhov xav tau ntawm ob.
