PP yog polypropylene, PET yog polyester. Hauv kev xav, ob qho tib si tsis muaj tshuaj lom, tab sis hais txog kev tiv taus kev laus thiab kev tiv taus huab cua, PP zoo dua rau cov khob dej, PP muaj kev tiv taus cua sov zoo, tuaj yeem tiv taus qhov kub siab txog 120 degrees, yog tib yam khoom siv yas uas tuaj yeem muab tso rau hauv lub tshuab hluav taws xob microwave.

Cov ntawv thov Polypropylene (PP): cov tais diav microwave, lauj kaub, thoob yas, lub plhaub thermos, hnab woven, thiab lwm yam. Cov yam ntxwv: kev ruaj khov tshuaj lom neeg siab, kev ua haujlwm zoo, kev tiv taus kub siab. Cov khoom siv microwave tuaj yeem siv cov khoom yas PP cim. Kev lom: tsis muaj tshuaj lom, tsis ua rau tib neeg lub cev. Cov polymer tuaj yeem muaj peb qhov qauv peb-seem: isometric, intergraphic, atactic polypropylene, thawj ob tuaj yeem crystallize, qhov tom kawg tsis tuaj yeem. Cov khoom polypropylene muaj nyob hauv khw yog cov qauv ntawm kev ua lag luam iso-gauge, melting point ntawm 164 ~ 170 degrees Celsius, qhov ceev ntawm crystalline yog 0.935 grams / cubic centimeters, qhov tsis huv yog 0.851 grams / cubic centimeters. Qhov tsis zoo tshaj plaws ntawm PP yog tias nws yooj yim rau oxidize thiab laus. Tam sim no nrog kev ntxiv cov antioxidants thiab ultraviolet absorbers kom kov yeej.
Cov ntawv thov Polyester (PET): cov fwj yas haus dej, cov fwj tshuaj, cov fwj tshuaj pleev ib ce, cov fwj roj, thiab ntau yam hau fwj, lub hau rwb thaiv tsev. Cov yam ntxwv: pob tshab zoo, tsis yooj yim tawg, ruaj khov tshuaj lom neeg zoo, haum rau ntau yam kua lossis khoom ntim tshuaj. Nws muaj kev tiv thaiv zoo rau cov duab ultraviolet. Kev lom: tsis muaj tshuaj lom.
Lub raj mis yas PET yog lub raj mis tseem ceeb hauv kev ntim dej haus. Lub luag haujlwm tseem ceeb hauv kev lag luam ntim dej haus hauv Suav teb yuav tsum yog lub raj mis yas PET, txog tam sim no, tsis muaj cov khoom siv zoo dua lossis zoo dua los hloov lub raj mis yas PET. Lub raj mis PP feem ntau yog ib kauj ruam txhaj tshuaj rub tshuab thiab ob kauj ruam cua sov rub tshuab, lub tshuab molding hauv lub raj mis PP muaj qhov zoo ntawm pob tshab, ruaj khov, tiv taus kub, thiab tus nqi kuj qis.

Cov fwj yas PP uas tiv taus cua sov zoo dua, cov duab ntawm lub raj mis zoo li rhiab heev, kev nyab xeeb, kev huv thiab cov ntsiab lus ntawm kev saib xyuas qhov tsis zoo, tus nqi pheej yig dua li PET, PS, PE thiab lwm yam khoom siv. Cov fwj yas PP hauv kev lag luam ntim dej haus hauv kev siv ntawm qhov ntsuas tau maj mam los ze rau lub raj mis PET, cov resins hloov kho, cov khoom siv permeability enhancers, thiab cov txuj ci tshuab thiab khoom siv los ntawm lub sijhawm mus rau lub sijhawm kom ua rau kev txhim kho ntawm PP thawv tuaj yeem hloov iav, PET thiab PVC thawv, qhov sib koom ua lag luam tab tom loj hlob.

Cov ntaub ntawv PP thiab PET muaj lawv tus kheej qhov zoo thiab yam ntxwv, tsis muaj qhov zoo lossis qhov phem kiag li, feem ntau nyob ntawm tus kheej xav tau thiab kev siv ntawm qhov xwm txheej los txiav txim siab, yog tias feem ntau siv ntawm qhov kub siab, koj tuaj yeem xaiv cov ntaub ntawv PP. Qhov saum toj no yog kev tshuaj xyuas ntawm PPkhob yasthiab cov khob yas PET, kuv vam tias nws tuaj yeem pab koj.
