Qhov twg yog pheej yig dua, PP lossis PET?

1. Txheej txheem cej luam ntawm PET Thiab PP Yas

PETsawv cev rau Polyethylene Terephthalate thiab yog cov thermoplastic polymer ua haujlwm hauv ntim cov dej haus thiab zaub mov. Nws yog nto moo rau kev ua kom muaj zog, meej, thiab rov ua dua tshiab, ua rau nws xaiv eco-friendly.

Polypropylene (PP) yog lwm yam khoom siv thermoplastic paub txog nws qhov yooj yim thiab tsis kam mus rau tshuaj. Nws yog dav siv nyob rau hauv ntim, automotive Cheebtsam, thiab textiles. PP muaj kev tiv thaiv kev qaug zog zoo heev thiab tseem tuaj yeem rov ua dua tshiab.

2. Kev sib piv ntawm PET vs. PP hauv tshuaj tiv thaiv

PET muaj cov tshuaj lom neeg tsis zoo thiab haum rau ntim khoom noj thiab dej haus. Nws muaj kev tiv thaiv zoo rau dej thiab qee cov roj tab sis yog soluble hauv cov kuab tshuaj xws li acetone thiab qee hom acids; yog li nws yuav tsis haum rau siv nyob rau hauv ib puag ncig uas siv penetrants los yog thaum cov tshuaj ib puag ncig yog unfriendly.

Ntawm qhov tod tes, PP yog tshuaj lom neeg heev thiab tiv taus ntau yam tshuaj xws li acids, alkalis, thiab cov kuab tshuaj. Qhov no ua rau PP yog ib qho khoom siv zoo heev rau kev siv hauv chav kuaj, kev ua tshuaj lom neeg, thiab ntim khoom ntawm cov khoom hnyav lossis corrosive.

 

3. Kev sib piv ntawm PET vs. PP hauv qhov kub thiab txias

PET muaj cov thermal stability siab dua mus txog 70-80 degree (158-176 degree F). Vim tias nws cov cua sov qis dua, PET yog qhov zoo tshaj plaws rau cov khoom siv uas tsis tas yuav tsum muaj qhov kub thiab txias, xws li lub raj mis dej haus, ntim khoom noj, thiab qee yam khoom siv.

Ntawm qhov tod tes, PP muaj qhov ua kom sov siab dua hauv feem ntau. Nws tuaj yeem tiv taus 100-120 degree C (212-248 degree F). Nws yog feem ntau siv rau microwavable zaub mov cia, thiab nws pib-daim ntawv thov, nrog rau kev siv hauv kev lag luam.

 

4. Kev sib piv ntawm PET vs. PP hauv cov khoom siv dag zog

Lub zog txhua yam ntawm PET muaj lub zog tensile siab thiab rigidity, uas tau ua rau nws nyuaj heev. Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog rau cov neeg siv qhov twg lub thawv yuav tsum muaj cov yam ntxwv ntawm cov khoom, xws li lub raj mis thiab cov hlab ntsha.

Txawm tiasPPmuab lub zog tensile zoo, nws ib txwm hloov tau ntau dua thiab muaj zog rau kev cuam tshuam. Vim li no, PP yog qhov zoo rau cov ntawv thov uas hu rau kev khoov lossis flexing ua raws li cov ntaub ntawv ntim cov yeeb yaj kiab thiab cov khoom siv tsheb.
Nyob rau hauv lub zog txhua yam ntawm PET vs. PP, PET nyhav kom muaj rigidity thaum PP feem ntau hloov tau.

 

5. Kev sib piv ntawm PET vs. PP hauv qhov tseeb

PET yog qhov tseeb thiab pob tshab, uas ua rau nws tsim nyog rau piv txwv hauv lub raj mis ntawm cov dej haus thiab ntim khoom noj. Cov cuab yeej no ua rau cov neeg siv khoom pom cov ntsiab lus vested hauv lawv, ua rau nws xaiv cov khoom ntim.

Ntawm qhov tod tes, PP feem ntau yog translucent thiab tsis haum rau cov ntawv thov uas cov khoom xav tau pom. Tsis tas li ntawd, PP tuaj yeem ua xim, tab sis nws tsis tsim tib qhov kev ntsuas pom tseeb li PET, ua rau nws tsis haum rau kev siv zoo nkauj.

 

6. Yam twg koj yuav tsum xaiv?

Thaum txiav txim siab ntawm PET vs. PP, nws yog ib qho tseem ceeb rau kev ntsuam xyuas koj cov kev xav tau tshwj xeeb thiab cov ntsiab lus uas yuav siv tau:

Nqi thiab muaj:

PP feem ntau raug nqi zoo rau cov ntawv thov loj vim nws cov nqi qis dua thiab muaj kev yooj yim dua. PET, txawm tias muaj peev xwm tsis tshua muaj zog, muaj qhov ua tau zoo uas tuaj yeem cuam tshuam cov txiaj ntsig zoo, tshwj xeeb tshaj yog rau cov khoom muaj nqis.

Xav txog koj cov peev nyiaj thaum xaiv qhov zoo ntawm PET vs. PP rau koj daim ntawv thov.
PP feem ntau pheej yig dua PET.
