Hais txog PET Raw Material
PET stands rau polyethylene terephthalate. Nws yog ib hom thermoplastic polymer cob.
PET yas yog qhov tseeb, tawv, thiab muaj cov roj zoo thiab cov khoom thaiv dej noo. Nws yog dav siv nyob rau hauv kev tsim cov dej haus fwj, ntim khoom noj, thiab lwm yam khoom ntim vim nws tuaj yeem pab khaws cov ntsiab lus tshiab.
Nws kuj tseem siv los ua cov hluavtaws fibers. Piv txwv li, polyester fibers hauv khaub ncaws feem ntau yog tsim los ntawm PET. Cov fibers no ruaj thiab wrinkle - resistant.
Tsis tas li ntawd, PET yog recyclable. Recycling PET pab txo cov khoom pov tseg thiab kev thov rau cov khoom siv tshiab.
Yam khoom twg yog tsim los ntawm PET khoom?
PET (polyethylene terephthalate) yog cov khoom siv ntau yam thiab siv los ua ntau yam khoom:
Ntim
• Lub raj mis dej haus: Feem ntau yog siv rau cov fwj dej, fwj dej qab zib, thiab lub raj mis kua txiv. Nws cov khoom thaiv zoo heev khaws cov pa roj carbon dioxide (hauv cov dej qab zib carbonated) thiab oxygen tawm, pab tswj kom zoo thiab tshiab ntawm cov dej haus.
• Cov Thawv Khoom Noj: Xws li cov thawv rau cov khaub ncaws hnav, cov kua ntses, thiab txiv laum huab xeeb. Lub pob tshab ntawm PET tso cai rau cov neeg siv khoom pom cov ntsiab lus, thiab nws txoj kev nyab xeeb ua rau nws haum rau kev sib cuag zaub mov.
• Tshuaj pleev ib ce thiab Toiletries Ntim: Siv rau fwj tshuaj zawv plaub hau, tshuaj pleev ib ce, thiab lwm yam khoom siv tu tus kheej.
Textiles
• Polyester Fibers: PET yog siv los tsim polyester fibers rau khaub ncaws, ntaub pua chaw pw, thiab upholstery. Polyester khaub ncaws paub txog nws cov durability, wrinkle - tsis kam, thiab ceev - ziab khoom. Nws yog siv los ua txhua yam ntawm lub tsho thiab ris mus rau cov khaub ncaws ncaws pob thiab cov khoom siv sab nraum zoov.
Lwm Daim Ntawv Thov
• Cov khoom siv hluav taws xob: Qee cov khoom siv hluav taws xob me me thiab cov casings tuaj yeem siv PET vim nws cov khoom tiv thaiv thiab tiv thaiv.
• Automotive: tuaj yeem siv rau hauv kev tsim khoom ntawm qee qhov chaw sab hauv, xws li headliners thiab lub rooj zaum npog, qhov uas nws cov kav ntev thiab yooj yim tuaj yeem siv tau.
Moulds ntawm PET cov khoom
PET (polyethylene terephthalate) cov khoom pwm ua lub luag haujlwm tseem ceeb hauv kev tsim ntau yam khoom PET.
Txhaj Moulding pwm
• Siv rau: Kev tsim khoom me me, khoom PET xws li qee cov khoom siv hluav taws xob ua los ntawm PET. Hauv kev txhaj tshuaj molding, molten PET yog txhaj rau hauv pwm kab noj hniav nyob rau hauv siab.
• Pwm Tsim: Cov pwm yuav tsum muaj cov rooj vag meej (qhov chaw nkag rau cov khoom siv molten) kom paub meej tias txawm tias txhaws ntawm kab noj hniav. Cov cua txias hauv pwm yog tsim los ua kom txias PET sai thiab sib npaug kom ua tiav cov duab xav tau thiab cov khoom siv kho tshuab.
Tshuab Moulding tshuab
• Siv rau: Tsim hollow PET cov khoom, tshwj xeeb tshaj yog lub raj mis thiab ntim. Hauv tshuab moulding, parison (ib lub raj ua ntej - zoo li tus qauv ntawm PET) yog muab tso rau hauv pwm thiab tom qab ntawd inflated coj cov pwm kab noj hniav.
• Pwm Nta: Cov pwm muaj qhov sib cais - tsim uas tso cai rau kev tshem tawm yooj yim ntawm cov khoom tiav hollow. Lawv kuj yuav tsum tau muab qhov sib npaug thickness faib thaum lub tshuab tshuab. Sab hauv ntawm cov pwm txiav txim siab cov duab sab nrauv thiab ua tiav ntawm PET lub raj mis lossis lub thawv.
Thermoforming pwm
• Siv rau: sib sau nyias-walled PET cov khoom xws li cov tais thiab cov hlwv pob. Hauv thermoforming, ib daim ntawv PET tiaj tus yog rhuab kom txog thaum nws pliable thiab ces kos rau hauv pwm kab noj hniav siv lub tshuab nqus tsev los yog siab.
• Pwm kev txiav txim siab: Cov pwm rau thermoforming feem ntau muaj cov kab noj hniav poj niam nrog ib qho kev ntxhib los mos lossis du nto nyob ntawm qhov xav tau ntawm cov khoom tiav. Lub qhov cua yog ib feem tseem ceeb ntawm cov pwm tsim los xyuas kom meej cov cua khiav tawm thaum lub sij hawm tsim kom ua tiav cov khoom tsim tau zoo.
