Tsis muaj qhov sib txawv ntawm PET thiab APET yas. Tus tsiaj yog polyester, uas muaj lub npe tshuaj lom neeg ntawm polyethylene terephthalate. Tus tsiaj tuaj yeem ua nrog cov polymers sib koom ua ob txoj hauv kev; amorphous los yog crystalline. Zoo, txhua yam koj tau ntsib nrog yog amorphous nrog ib qho kev zam loj; Cov tais zaub mov microwave uas, yog ua los ntawm tus tsiaj, yog tsim los ntawm C-PET (crystallized PET). Qhov tseem ceeb txhua tus tsiaj ntawv ntshiab suav nrog Mylar thiab cov fwj dej tau tsim los ntawm A-PET (amorphous PET) thiab ntau qhov, "A" tsuas yog tso tseg.
Mobius lub voj rov ua lub cim rau polyester yog PET nrog tus lej 1, yog li coob leej neeg xa mus rau polyester li PET. Lwm tus xav kom muaj qhov tshwj xeeb ntau dua, los ntawm kev qhia seb polyester yog crystalline C-PET, amorphous APET, rov siv RPET, lossis glycol hloov PETG. Cov no yog cov kev hloov pauv me me, npaj kom yooj yim ua cov polyester rau lub hom phiaj kawg cov khoom, txawm tias los ntawm kev txhaj tshuaj molding, tshuab moulding, thermoforming, lossis txuas ntxiv nrog rau kev ua tiav zoo li txiav txiav.
PETG los nrog tus nqi taw tes ntau dua thiab yooj yim dua tuag txiav dua APET siv cov cuab yeej txiav txiav tuag. Nyob rau tib lub sijhawm, nws tseem softer thiab khawb tau yooj yim dua li APET. Cov hloov pauv uas tsis muaj cov cuab yeej tsim nyog tuag txiav APET feem ntau ua haujlwm nrog PETG vim qhov tseeb tias PETG softer thiab khawb yooj yim dua, yog li nws feem ntau yog poly npog (qhov no yog "Saran qhwv" hom npog). Daim npog qhov ncauj no yuav tsum tau muab tshem tawm ntawm ib sab thaum luam ntawv, tab sis daim npog feem ntau yog sab laug ntawm lwm sab thaum tuag txiav kom tiv thaiv khawb. Nws siv sijhawm ntev heev thiab vim li no kim dua kom tshem cov npog ntsej muag poly, tshwj xeeb tshaj yog tias luam tawm ntau nplooj ntawv.
Ntau lub ntsiab lus ntawm kev muag khoom yog tsim los ntawm PETG, txij li lawv feem ntau hnyav ntsuas thiab tawv kom tuag txiav. Lwm qhov laj thawj yog tias daim npog ntsej muag poly tuaj yeem sab laug los tiv thaiv cov zaub thaum tuav thiab thauj khoom thiab tom qab ntawd tshem tawm thaum cov zaub raug teeb tsa. Qhov no yog qhov laj thawj tseem ceeb vim li cas ntau tus neeg tsim qauv tau hais qhia PETG rau qhov chaw muag khoom tsis nkag siab tias APET lossis PETG yog cov khoom tsim nyog tshaj plaws rau lub hom phiaj siv kawg lossis ua (luam ntawv, txiav txiav, gluing, thiab lwm yam). APET feem ntau muaj txog li 0.030 ″ tuab, hos PETG feem ntau pib ntawm 0.020 ″.
Muaj lwm qhov sib txawv me me ntawm PETG thiab APET, thiab yog tias koj tsis paub txog cov txiaj ntsig thiab thim rov qab ntawm PET li cas, nco txog lub npe ua rau tsis meej pem, tab sis nws muaj kev nyab xeeb los hais tias txhua qhov saum toj no hais txog polyester thiab, los ntawm qhov rov ua dua ntawm qhov pom, lawv txhua tus raug kho zoo ib yam.
