PET khoom yog dab tsi? --Comprehensive Analysis of Polyethylene Terephthalate (PET)
Taw qhia: Cov Ntsiab Cai ntawm PET
PET yog dab tsi? Qhov no yog ib lo lus nug uas ntau tus neeg feem ntau ntsib hauv lawv lub neej txhua hnub. PET, hu ua Polyethylene Terephthalate, yog cov khoom siv thermoplastic polyester uas tau siv dav hauv kev ntim khoom thiab kev lag luam textile. Nrog nws cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, nws tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb hauv kev tsim khoom niaj hnub no.
Cov qauv tshuaj thiab cov khoom ntawm PET
PET yog linear polymer, feem ntau yog tsim los ntawm polycondensation ntawm terephthalic acid (TPA) thiab ethylene glycol (EG) nyob rau hauv tej yam kev mob. Cov khoom siv tau zoo crystallinity thiab txhua yam muaj zog thiab yog cov pob tshab heev.PET muaj qhov melting point ntawm ib ncig ntawm 250 ° C thiab kub resistant, tswj nws cov khoom siv kho mob ntawm qhov kub thiab txias. Nws kuj muaj cov tshuaj tiv thaiv zoo heev thiab UV tsis kam, tso cai rau nws nyob ruaj khov hauv ntau qhov chaw hnyav.
PET cov cheeb tsam tseem ceeb ntawm kev thov
Thaum peb paub tias PET yog dab tsi, cia peb saib nws cov ntawv thov.PET yog dav siv hauv cov khoom ntim, tshwj xeeb tshaj yog hauv kev lag luam lub raj mis haus. Vim nws qhov zoo tshaj plaws pob tshab thiab thaiv cov khoom, PET lub raj mis tuav lub lag luam loj hauv kev ntim khoom noj thiab dej haus. Ntxiv nrog rau kev ntim khoom, PET kuj tseem siv rau hauv kev lag luam textile, feem ntau yog siv rau kev tsim cov polyester fibers, uas yog siv dav hauv cov khaub ncaws, tsev textiles, thiab lwm yam. PET kuj tuaj yeem siv los ntawm cov txheej txheem tsim dua tshiab, ua rau cov khoom siv zoo nkauj.
Kev tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm cov khoom siv PET
Qhov zoo ntawm PET suav nrog lub zog siab, ua haujlwm ntev, lub teeb yuag thiab rov ua dua tshiab. Nws cov khoom thaiv zoo heev cia cov zaub mov thiab dej haus hauv lub pob kom nyob twj ywm tshiab. Ntxiv mus, cov ntaub ntawv PET yog 100% recyclable, uas yog ib qho tseem ceeb rau kev tiv thaiv ib puag ncig thiab kev txuag cov peev txheej.PET kuj muaj qee qhov tsis txaus, xws li nws lub peev xwm los tsim cov lej ntawm ethylene glycol lossis terephthalic acid monomer tso rau hauv qee yam mob, txawm hais tias cov tshuaj no muaj kev cuam tshuam tsawg rau tib neeg kev noj qab haus huv, lawv tseem yuav tsum tau saib xyuas thaum siv.
Hauv cov ntsiab lus: PET yav tom ntej
Cov lus nug ntawm yam khoom siv PET yog dab tsi tau teb ua tiav. Cov ntaub ntawv PET tau dhau los ua ib feem tseem ceeb ntawm kev lag luam niaj hnub no vim lawv cov khoom zoo heev ntawm lub cev thiab ntau yam ntawm daim ntawv thov kev cia siab. Nrog rau kev txhim kho ntawm kev paub txog ib puag ncig thiab kev tsim cov thev naus laus zis rov ua dua tshiab, daim ntawv thov ntau yam ntawm PET yuav tsum tau nthuav dav ntxiv, thaum nws cov txheej txheem tsim khoom thiab cov txheej txheem siv yuav txuas ntxiv tshiab. Nyob rau hauv lub neej yav tom ntej, PET yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ntim khoom, textile thiab lwm yam lag luam, txhawb kev tsim kho kom ruaj khov ntawm cov kev lag luam no.
