Kev ruaj ntseg
Khoom noj khoom haus- qib PET yog siv dav hauv ntim khoom noj thiab dej haus thiab tau lees paub zoo rau nws txoj kev nyab xeeb thiab ruaj khov. Nws tsis tso cov tshuaj phem thiab ua raws li cov qauv kev nyab xeeb thoob ntiaj teb, uas tso cai rau cov neeg siv khoom kom tau txais kev nyab xeeb thaum siv. Txawm li cas los xij, ib qho yuav tsum tau saib xyuas tshwj xeeb: PET tuaj yeem tso qee yam teeb meem, xws li DEHP +, nyob rau hauv qhov kub thiab txias. Yog li ntawd, thaum siv cov thawv PET, nco ntsoov kom tsis txhob muaj qhov kub thiab txias los tiv thaiv kev tso tawm cov khoom tsis zoo.
Khoom noj khoom haus- qib PP yog nyob txhua qhov chaw hauv peb lub neej niaj hnub, xws li cov khoom tshiab - khaws cov thawv hauv cov khw muag khoom noj khoom haus thiab lub thawv noj su microwave, ntau yam uas yog ua los ntawm PP. Vim li cas nws thiaj li nrov? Ua ntej tshaj plaws, cov khoom no tsis yog - tshuaj lom, tsis qab thiab tsw, ua rau nws muaj kev nyab xeeb heev rau kev siv. Tsis tas li ntawd, nws muaj cov cua kub zoo heev thiab tuaj yeem muab tso rau hauv lub microwave kom sov zaub mov yam tsis muaj teeb meem. Nws yuav tsis deform thaum rhuab zoo li qee cov yas thiab tej zaum kuj tso cov khoom tsis zoo. Tam sim no, nws cov tshuaj stability kuj zoo heev. Raws li kev siv ib txwm, nws tsis yooj yim rau kev hnov mob nrog lwm yam tshuaj.
Qhov tseem ceeb tshaj, cov khoom siv PP tsis tas yuav tsum tau ntxiv cov khoom tsis zoo thaum lub sijhawm tsim khoom. Nyob rau hauv qhov kub thiab txias, nws yuav tsis decompose bisphenol A*, ib yam tshuaj uas tsim kev puas tsuaj rau tib neeg lub cev. Qhov no txhais tau hais tias cov tais diav los yog ntim khoom ua los ntawm PP cov khoom muaj kev nyab xeeb thiab tshwj xeeb tshaj yog haum rau khaws cov zaub mov. Yog li ntawd, thaum xaiv cov ntim khoom noj lossis cov tais diav, cov khoom siv PP tuaj yeem muab qhov tseem ceeb. Tom qab tag nrho, kev nyab xeeb los ua ntej.
Pob tshab
Cov khoom noj khoom haus - qib PET cov khoom muaj qhov pom tseeb heev, tso cai rau koj pom cov zaub mov sab hauv ib nrais muag, thiab cov tsos thiab qhov zoo tau pom meej meej. Yog li ntawd, nws yog qhov tshwj xeeb tshaj yog siv rau hauv ntim khoom uas yuav tsum tau muab tso rau hauv cov zaub mov, xws li lub raj mis dej haus uas peb nquag haus, thiab cov kaus poom zaub mov rau biscuits thiab candies. Feem ntau ntawm cov pob no yog ua los ntawm PET. Vim li cas siv nws? Nws yog vim cov tub lag luam xav qhia qhov zoo tshaj plaws ntawm lawv cov khoom rau cov neeg siv khoom thiab nyiam lawv mus yuav. Ntxiv mus, hom ntim no tsis tsuas yog zoo li tshiab thiab huv si, tab sis kuj tiv thaiv cov khoom noj rau qee yam, tiv thaiv kom tsis txhob ntub thiab deforming, xyuas kom meej tias cov zaub mov mus txog ntawm txhais tes ntawm cov neeg siv khoom zoo thiab nyob rau hauv qhov zoo.
Khoom noj khoom haus-qib PP muaj qhov tsis tshua pom tseeb, feem ntau yog translucent. Txawm hais tias nws muaj lub teeb xa hluav taws xob tsis zoo, nws muaj ntau yam kev siv. Siv lub thawv yogurt piv txwv. Cov khoom siv PP translucent tso cai rau tib neeg kom pom qhov tuab ntawm cov yogurt, thaum tseem ua rau muaj kev nkag siab tsis meej rau cov khoom. Tseem muaj cov tais uas nquag pom hauv cov khw muag khoom loj. Cov tais nqaij tshiab yog ib qho piv txwv. Pallets ua los ntawm cov khoom siv PP yog tawg - tiv taus thiab siv tau, thiab lawv cov ntaub ntawv zoo nkauj zoo li huv thiab huv. Kev siv cov khoom PP los ua cov thawv ntim khoom noj thiab cov tais tsis tuaj yeem ua tau raws li qhov xav tau, tab sis kuj ua kom muaj kev nyab xeeb ntawm zaub mov.
Thaum tshav kub kub kuj
Kev tiv thaiv tshav kub yog ib qho tseem ceeb ntawm cov zaub mov -qib PET. Txawm hais tias nws yog cua sov- tiv taus, nws tsis tuaj yeem tiv taus qhov kub thiab txias. Thaum qhov kub nce mus txog 70-80 degree, qhov chaw ntawm PET ntim yuav deform thiab poob nws cov duab qub. Yog li ntawd, cov zaub mov- qib PET tsis haum rau siv nyob rau hauv cov xwm txheej uas siab -kub kom tsis muaj menyuam lossis cua sov yuav tsum tau ua. Piv txwv li, hauv cov txheej txheem tsim khoom noj, nws tsis muaj txiaj ntsig hauv qee qhov kev sib txuas uas yuav tsum tau ntim cov khoom kub thiab kom tsis muaj menyuam. Yog tias lub ntim PET siv los tuav cov dej kub, nws yuav yooj yim deform, ua rau muaj kev puas tsuaj los yog siv tsis tau. Yog li ntawd, thaum xaiv cov khoom ntim, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov kub thiab txias ntawm kev ua zaub mov kom tsis txhob muaj teeb meem tshwm sim los ntawm cov khoom ntim tsis muaj cua sov.
Khoom noj khoom haus-qib PP muaj qhov ua tau zoo heev thaum tshav kub kub, feem ntau ua rau kub ntawm 110℃thiab 120 degree. Nws tseem yog tib cov yas uas tuaj yeem ua kom sov ncaj qha rau hauv lub microwave, uas yog qhov ua tau zoo heev. Yog tias cov khoom noj yuav tsum muaj siab -kub kom tsis muaj menyuam lossis cua sov ua ntej ntim, PP ntim yog qhov zoo tagnrho. Ntau lub thawv ntim khoom noj peb feem ntau siv rau pluas noj, nrog rau cov cua sov- thiab- noj su lub thawv muag hauv khw muag khoom, yog ua los ntawm PP. Siv nws los tuav cov zaub mov thiab cua sov hauv microwave yog yooj yim thiab nyab xeeb. Tsis tas yuav txhawj xeeb txog nws melting los yog tso cov khoom tsis zoo. Qhov no yooj yim heev hauv lub neej txhua hnub.
Tshuaj tiv thaiv
Khoom noj khoom haus- qib PET muaj kev ua siab ntev rau cov kua qaub thiab alkalis thiab tuaj yeem tiv taus cov acidic thiab alkaline ib puag ncig hauv cov khoom noj txhua hnub. Tab sis yog tias koj ntsib cov oxidizing muaj zog lossis cov kuab tshuaj organic, qhov ntawd yuav tsis ua haujlwm. Piv txwv li, muaj zog oxidizers xws li tshuaj dawb thiab tshuaj tua kab mob, nrog rau tej yam xws li cov xim thinner, yuav corrode PET tom qab kev sib cuag, ua rau nws nkig, deformed, los yog puas. Yog li ntawd, thaum ntim cov khoom noj, nws yog qhov zoo tshaj plaws kom tsis txhob muaj cov khoom no kom ntseeg tau tias kev ntim khoom thiab kev nyab xeeb ntawm cov khoom noj.
Khoom noj khoom haus-qib PP muaj cov tshuaj lom neeg ruaj khov thiab tsis muaj zog rau cov tshuaj feem ntau, tshwj tsis yog cov oxidants muaj zog. Cov khoom no yog nrov nyob rau hauv ob qho tib si zaub mov thiab industrial sectors. Piv txwv li, cov thawv ntim khoom noj thiab lub thawv noj su microwave yog qhov zoo tagnrho rau khaws cov zaub mov, kom ntseeg tau tias lawv muaj kev tiv thaiv los ntawm tshuaj tua kab mob. Kuj tseem muaj qee qhov kev lag luam ntim tshuaj uas tuaj yeem ua los ntawm cov khoom siv PP yog tias acidity lossis alkalinity tsis muaj zog heev. Nws txawm pom kev siv hauv ntim cov tshuaj pleev ib ce thiab cov khoom siv tu, tiv thaiv cov tshuaj lom neeg tsis pub dhau los ntawm cov khoom ntim khoom thiab ua kom cov khoom zoo ib yam. Hauv luv luv, tsuav nws tsis ntsib cov oxidants muaj zog, PP cov khoom tuaj yeem tuav ruaj khov thiab yog qhov kev xaiv zoo rau kev ntim khoom uas tiv thaiv cov tshuaj yaig.
Kev ua tau zoo
Khoom noj khoom haus- qib PET muaj teeb meem me ntsis rau kev ua haujlwm. Nws yuav tsum tau qhuav kom huv si ua ntej nws tuaj yeem molded. Yog tias nws tsis qhuav tag, qhov tsis xws luag tuaj yeem tshwm sim tau yooj yim thaum lub sijhawm ua, xws li npuas lossis impurities ntawm qhov chaw ntawm cov khoom. Tsis tas li ntawd, PET yog qhov nyuaj rau kev ua haujlwm, thiab cov khoom siv thiab cov txheej txheem yuav tsum tau ua thaum lub sijhawm tsim khoom yog nruj dua. Qhov no ncaj qha ua rau nws cov nqi tsim khoom siab dua li lwm cov ntaub ntawv yas. Yog li ntawd, cov khoom PET feem ntau kim dua. Txawm li cas los xij, nws tseem siv dav hauv kev ntim khoom xws li lub raj mis dej haus thiab cov thawv ntim khoom noj, feem ntau yog vim nws qhov kev ua tau zoo, siab pob tshab, muaj peev xwm tso saib zaub mov, thiab ua kom muaj kev nyab xeeb.
Khoom noj khoom haus-qib PP muaj kev ua tau zoo heev thiab tuaj yeem hloov tau yooj yim rau ntau yam kev ua haujlwm nyuaj, xws li kev txhaj tshuaj molding, extrusion, thiab tshuab molding, uas nws tuaj yeem ua tiav zoo heev. Thaum lub sij hawm tsim cov txheej txheem, PP tsis xav tau cov khoom siv nruj tib yam thiab cov txheej txheem raws li qee cov khoom siv yas, thiab kuj yooj yim rau pwm, ua rau cov nqi tsim khoom tsawg. Yog li ntawd, zaub mov -qib PP yog tshwj xeeb tshaj yog nrov nyob rau hauv kev lag luam ntim. Piv txwv li, ntau ntawm peb cov thawv ntim khoom noj txhua hnub thiab yogurt khob yog ua los ntawm PP. Nrog tus nqi qis, zoo zoo thiab muaj peev xwm ua tau raws li kev xav tau ntawm kev lag luam, nws tsis muaj qhov xav tias nws muaj qhov chaw nyob hauv cov khoom ntim khoom noj.
Siv tau Scenarios
