Puas yog cov khoom noj-qib rpet thiab pellets muaj kev nyab xeeb?
Nkag Siab Cov Khoom Noj-Qib RPET
Nyob rau hauv ib lub sij hawm era ntawm kev nce ib puag ncig thiab nrhiav kev txhim kho kom ruaj khov,Cov Khoom Noj-Qib RPET(rov ua dua polyethylene terephthalate) tau dhau los ua cov khoom tseem ceeb hauv kev lag luam ntim khoom, tshwj xeeb yog cov khoom noj ntim khoom tshwj xeeb. Ntawm nws cov tub ntxhais, RPET yog ib daim ntawv rov ua dua tshiab, ib thermoplicity polymer resin dav siv hauv kev tsim cov tshuaj yas, ntim, thiab ntau yam ntim khoom. Lub "rov ua dua tshiab" hauv RPET txhais tau tias nws yog tsim los ntawm cov neeg siv khoom tom qab lossis tom qab yug cov tsiaj, muab cov ntaub pua khib nyiab tshiab lub neej.
Dab tsi rpet thiab nws muaj dab tsi
Nyob rau theem molecular, cov muaj pes tsawg leeg ntawm RPET yog qhov tseem ceeb tib yam li nkauj xwb tus tsiaj. Nws yog ua los ntawm kev rov ua dua cov chav ethylene glycol thiab terephthalic acid, uas tau txuas rau ua kom cov ntaub ntawv ntev ntev. Txawm li cas los xij, vim nws cov khoom siv ua dua tshiab, qhov zoo thiab huv si ntawm rpet tuaj yeem sib txawv raws li qhov khoom siv rov ua dua tshiab thiab cov txheej txheem recycling. Nov yog qhov uas cov tswv yim ntawm cov zaub mov-qib rpet yog qhov tseem ceeb.
Cov txheej txheem ntau lawm ntawm cov khoom noj-qib RPET
Cov txheej txheem ntau lawm ntawm cov zaub mov-qib rpet yog ntau yam thiab nruj tshaj li ntawd ntawm cov tib neeg rov ua dua. Nws pib nrog kev sau los ntawm cov neeg siv khoom tom qab cov neeg siv khoom tsiaj. Cov fwj no feem ntau yog los ntawm cov chaw rov ua dua tshiab, uas lawv raug txheeb raws li lawv hom, xim thiab mob. Tom qab xaiv, lub hwj yog tsoo rau hauv cov khoom me me. Cov kauj ruam thawj zaug tawg cia loj hwj rau hauv cov kev tswj hwm ntau dua rau kev ua txuas ntxiv. Tom ntej no tseem ceeb theem yog kev tu thiab huv txheej txheem. Tsis zoo li cov kev ua dua tshiab ib txwm ua, cov nyiaj-cov nyiaj-cov nyiaj-cov nyiaj-ua kom huv huv kom ntseeg tau tias nws muaj kev nyab xeeb rau kev sib cuag zaub mov. Cov Fragments tau meej ntxuav kom tshem tawm cov av saum npoo av, cov ntawv lo thiab cov nplaum. Lawv mam li yauv ua kev kho mob thiab kev kho mob lub cev. For example, they may be heated to high temperatures in a process called "melt filtration", which helps remove any remaining contaminants, including colorants and additives from the original bottles. Ib qho ntxiv, cov tswv yim ua kom tau muaj zoo xws li muaj cov khoom siv roj polymerization (SSP)
Cov Qauv Kev Nyab Xeeb thiab Cov Cai
Kev nyab xeeb ntawm cov zaub mov-qib rpet tseem ceeb thiab yog nruj me ntsis tswj hwm los ntawm ntau yam kev ua haujlwm thoob ntiaj teb thiab hauv cheeb tsam. Nyob rau hauv Tebchaws Asmeskas, Chaw Tswj Xyuas Khoom Noj thiab Tshuaj Noj (FDA) ua si lub luag haujlwm tseem ceeb hauv kev tswj hwm kev siv cov khoom siv uas ua dua tshiab, suav nrog RPET, hauv ntim zaub mov. FDA tau tsim txoj kev qhia dav dav thiab cov kev tswj uas cov tuam ntxhab yuav tsum ua raws li kev nyab xeeb ntawm cov ntaub ntawv tiv toj zaub mov noj. Cov kev cai no cov kev pab them rau cov khoom siv uas tuaj yeem siv tau, cov theem uas siv tau los ntawm cov txheej txheem paug, thiab cov txheej txheem sim uas yuav tsum tau ua.
Cov txiaj ntsig ntawm kev siv cov khoom noj-qib rppet chips thiab pellets
Muaj ntau cov txiaj ntsig rau kev siv cov khoom noj-qib rppet chips thiab pellets, suav nrog ib puag ncig, nyiaj txiag, thiab cov lag luam muaj feem xyuam.
Cov txiaj ntsig ib puag ncig
Kev Koom Tes Rau Hom Khoom Siv
Los ntawm ib puag ncig lub tswv yim, cov nyiaj-rpet loj heev txo cov khib nyiab yas. Los ntawm kev rov ua dua tshiab cov neeg siv khoom tsiaj rau hauv RPET rau cov khoom noj ntim khoom, muaj cov yas loj uas yuav txwv tsis pub muaj qhov chaw pov tseg lossis dej hiav txwv. Qhov no tsis tsuas yog pab kom txuag tau cov khoom siv ntuj, tab sis kuj tseem txo cov kev cuam tshuam ib puag ncig nrog cov nkauj xwb cov tsiaj ntau lawm. Piv rau cov tsim khoom tsiaj los ntawm cov ntaub ntawv raw, RPET yuav tsum muaj tsawg dua lub zog los tsim thiab muaj cov hneev taw txo qis dua. Piv txwv li, cov kev tshawb fawb tau pom tias siv rpet tuaj yeem txo cov roj tsev cog khoom muaj nce txog 50% piv rau nkauj xwb cov tsiaj ntau lawm.
Cov Kev Pab Nyiaj Txiag
Cov khoom noj-qib rpet kuj muaj qhov zoo nyob rau hauv cov nqe lus ntawm kev lag luam. Raws li kev thov kom muaj kev ruaj khov ntim cov kev daws teeb meem, siv RPET tuaj yeem raug nqi rau cov neeg tsim khoom lag luam. Txawm hais tias thawj zaug kev nqis peev hauv cov chaw ua haujlwm thiab cov txheej txheem ntau lawm rau cov nqi khoom noj muaj txiaj ntsig zoo, raw cov khoom siv tau tuaj yeem txo nyob rau hauv ntev. Vim hais tias RPET yog tsim los ntawm cov khoom siv ua kom rov ua dua tshiab, nws tus nqi feem ntau qis dua li nkauj xwb tus tsiaj. Ib qho ntxiv, raws li tsoomfwv thoob ntiaj teb pom cov cai thiab kev txhawb nqa los txhawb kev siv cov khoom siv-cov nyiaj muas noj thiab lwm yam kev txhawb nqa nyiaj txiag.
Kev Koom Tes Rau Hom Khoom Siv
Nyob rau hauv cov nqe lus ntawm hom duab, siv cov khoom noj-qib rpet ua kom cov tuam txhab ua tiav lawv cov hom phiaj ruaj khov. Cov neeg siv khoom niaj hnub no yog ib puag ncig ntau dua li tau ua ntej thiab muaj peev xwm txhawb nqa cov hom phiaj uas tau ua rau muaj kev cog lus rau kev ceev faj. Los ntawm kev siv rpet hauv lawv cov khoom ntim khoom noj, hom tuaj yeem sib txuas lus lawv kev cog lus kom txo cov khib nyiab thiab tiv thaiv ib puag ncig. Qhov no tuaj yeem txhawb hom kev ncaj ncees, nyiam cov neeg yuav khoom tshiab, thiab hom sib txawv hauv kev sib tw ua lag luam.
Zhejiang Haili Environmental tiv thaiv Technology Co., Ltd.Txuas ntxiv mus tsav tsheb tshiab hauv cov khoom noj-qib rpet ntau lawm. Los ntawm kev tshawb fawb txuas ntxiv thiab kev txhim kho, lub tuam txhab txuas ntxiv txhawm rau txhim kho kom zoo thiab ua tau zoo ntawm nws cov khoom lag luam rpet thaum nruj dua rau cov qauv kev nyab xeeb thoob ntiaj teb. Lawv cov kev siv zog pab txhawb cov kev hloov pauv thoob ntiaj teb, muab cov kev nyab xeeb zoo, ib puag ncig zoo rau cov zaub mov thiab dej haus kev lag luam. Raws li qhov kev thov rau kev ntim khoom ruaj khov ntxiv kom loj hlob, cov khoom noj khoom haus-cov roj ntsha
