PET txawv ntawm lwm hom yas li cas?

PET yas yog qhov kev xaiv ntim khoom ruaj khov thiab hom yas tseem ceeb siv rau lub raj mis dej haus vim nws cov tshuaj tiv thaiv zoo heev rau cov ntaub ntawv organic thiab dej thiab nws lub zog-rau-qhov hnyav piv. Ntawm no, peb yuav tshawb xyuas seb lub raj mis PET yog dab tsi, ntsuas lawv cov txiaj ntsig, thiab muab piv rau lwm hom yas.

PET yog dab tsi?

PET, polyethylene terephthalate (tseem hu ua PETE) yog cov khoom siv hluav taws xob muaj zog, tawv tawv uas yog cov tsev neeg thermoplastic, uas txhais tau tias nws tuaj yeem ua kom sov, yaj, thiab txias rau ntau yam duab thiab ntau thiab tsawg. Ua los ntawm kev sib xyaw ntawm cov roj thiab cov tshuaj petrochemical, nws yog qhov nrov hauv kev tsim cov raj mis thiab jars. Qhov tseeb, yuav luag txhua lub raj mis yas yog tsim los ntawm PET. Nws yog tsim rau ntau yam dej haus, nrog rau cov dej carbonated, uas tsis yog-carbonated thiab dilutable dej haus, kua txiv hmab txiv ntoo thiab cov dej hauv lub raj mis.

Cov khoom muab kev tiv thaiv tiv thaiv cov pa roj carbon dioxide thiab lub teeb, tshem tawm cov kab mob, thiab yog EU / NSF / FDA kuaj thiab pom zoo. PET yog lub teeb yuag, muaj qhov pom tseeb heev thiab zoo li iav thaum khov. Nws muaj zog, tsis muaj zog thiab tawg-pov thawj, tso cai rau cov khoom ua tau raws li cov qauv kev nyab xeeb siab rau cov khoom noj, dej haus thiab cov khoom tu tus kheej. Nws muaj zog txaus los mus rau HPP (High Pressure Processing) - ib daim ntawv uas tsis muaj cua sov pasteurization.

PET puas yog ib puag ncig zoo dua li lwm hom yas?

PET yog qhov kev xaiv zoo tshaj plaws rau lub raj mis yas (thiab lwm yam kev siv) vim nws yog 100% recyclable thiab ruaj khov heev. Nws tuaj yeem rov qab tau thiab rov ua dua tshiab rau hauv cov khoom tshiab dua, txo cov peev txheej pov tseg. Qhov no txawv ntawm lwm hom yas xws li polyvinyl chloride (PVC), tsawg ntom polyethylene (LDPE), polypropylene (PP), polystyrene (PS), uas yog siv rau hauv cov hnab yas, cov hnab yas pov tseg, cov khoom noj thiab cov khob pov tseg raws li. .

PET kuj tseem muaj cov pa roj carbon tsawg vim tias nws siv lub zog tsawg dua hauv cov txheej txheem tsim khoom, uas pab cov neeg siv khoom txo qis kev siv hluav taws xob tag nrho. Vim nws lub teeb yuag, lub tuam txhab muaj peev xwm thauj cov khoom PET ntau thiab txo cov pa roj carbon emissions thaum lub sij hawm thauj mus los. Qhov no kuj ua rau nws xaiv kev lag luam rau kev lag luam.

PET lub neej voj voog

Cov khoom siv PET tuaj yeem muaj lub neej ntev thiab tsim cov pov tseg yas me me yog tias cov neeg siv khoom pov tseg kom raug. Cov khoom siv tau yooj yim rov ua dua thiab rov ua dua PET yog cov khoom muaj txiaj ntsig nrog lub peev xwm los kaw lub voj. Cov khoom siv PET feem ntau tau sau meej meej nrog # 1 resin code, qhia rau cov neeg siv khoom tias nws yog cov khoom siv PET tag nrho. Piv txwv li, qee lub thawv yas muaj ntau txheej, thiab qee tus neeg pom nws siv sijhawm los txheeb xyuas kom raug.

Rov ua dua cov ntsiab lus

Cov khoom siv PET tuaj yeem tsim tau siv PET rov ua dua tshiab. Piv txwv li, ib-liter refillable PET lub raj mis yog tsim los ntawm 30% recycled cov ntsiab lus thiab muaj 81% qis carbon hneev taw dua li lub khob iav refillable. Qee qhov ntawm peb cov qauv tsim tuaj yeem tsim tau siv 100% cov khoom siv rov ua dua tshiab - tshem tawm cov yas yas los ntawm cov txheej txheem tsim khoom yuav pab txuag tau li 75% ntawm koj cov pa roj carbon hneev taw.

Puas yog PET muaj kev nyab xeeb dua li lwm hom yas?

Raws li tau hais ua ntej, PET yog shatterproof thiab yuav tsis ua rau muaj kev puas tsuaj yog tawg lossis puas - nws yog lub npe hu ua "kev nyab xeeb" yas. PET kuj tsis muaj bisphenol A (BPA), ntau cov tshuaj phem. Qee hom yas muaj cov tshuaj no, uas tau tshaj tawm tias cuam tshuam nrog lub cev endocrine system, uas ua rau muaj kev cuam tshuam rau kev noj qab haus huv. Qhov no yog qhov laj thawj tseem ceeb uas ntau tus neeg siv khoom hloov pauv los ntawm polycarbonate rau PET dej txias, ib hom yas uas feem ntau muaj BPA.

Zuag qhia tag nrho, PET yog ib qho kev nyab xeeb, huv si ntim tshuaj thiab tau pom zoo los ntawm pawg neeg saib xyuas kev noj qab haus huv thiab kev nyab xeeb. Nws muaj pes tsawg leeg txhais tau hais tias nws yuav tsis hnov ​​​​mob nrog cov khoom noj lossis cov kua uas tuaj yeem cuam tshuam nrog cov khoom, ua rau PET tsis muaj kev pheej hmoo thiab nyab xeeb.
