Kev faib tawm ntawm cov thawv yas

Raws li kev siv cov khoom siv sib txawv, cov thawv yas feem ntau muaj cov cim kev tshaj lij kom paub qhov txawv ntawm lawv:
1-PET polyethylene terephthalate: Nws tuaj yeem tsim cov carcinogens tom qab siv kaum lub hlis. Cov khoom siv yas no muaj qhov ua tau zoo ntawm kev muab pov tseg tom qab siv thiab feem ntau yog siv los ua cov dej ntxhia dej, lub raj mis mis, thiab lwm yam. Tsis haum rau khaws cov dej txias los yog kub dhau, vim nws tuaj yeem yooj yim precipitate carcinogenic tshuaj DEHP.
2-HDPE (High Density Polyethylene): Tsis yooj yim los ntxuav, ua rau cov kab mob loj hlob, tsis pom zoo siv dua. Feem ntau, cov fwj tshuaj pleev ib ce thiab da dej gel yas ntim fwj yog cov khoom siv no.
3-PVC (polyvinyl chloride): Nws yooj yim tso tawm cov khoom tsis zoo thaum raug kub thiab roj, thiab feem ntau siv rau hauv cov tsho tiv nag, cov khoom ua si yas, cov khoom siv hauv tsev, thiab lwm yam.
4-LDPE (Low Density Polyethylene): Cov khoom tsis zoo yog yooj yim tsim thaum kub kub, thiab hnab yas, cling films, thiab lwm yam ntaub ntawv uas feem ntau siv nyob rau hauv lub neej txhua hnub yog ua los ntawm cov khoom no. Muab cov zaub mov qhwv hauv hnab yas thiab cua sov nws tuaj yeem yooj yim yaj cov khoom tsis zoo nyob rau hauv muaj roj.
5-PP (polypropylene): tsuas yog cov khoom siv uas siv tau rau microwave cua sov, cov khoom siv zoo heev. Tom qab ua tib zoo tu, nws tuaj yeem rov qab siv dua, tab sis feem ntau lub hau ntawm lub thawv yas microwave tsis yog ua los ntawm cov khoom PP, yog li nws raug nquahu kom tshem lub hau thaum cua sov.
6-PS (polystyrene): tshav kub-resistant thiab txias resistant, nws yog cov khoom siv los tsim lub tais zoo li cov noodle thawv thiab cov thawv ntim khoom noj ceev ceev. Peb tsis tuaj yeem muab tso rau hauv lub microwave vim nws tuaj yeem tsim cov tshuaj vim qhov kub thiab txias. Yog li ntawd, peb yuav tsum txo qis kev siv cov thawv ntim khoom noj ceev kom ntim cov zaub mov kub.
7-AB (Acrylonitrile Butadiene Baijiu Cool Pad Diene): tsis tuaj yeem siv rau ntim khoom noj, tab sis ua ntej xyoo 2008, code 7 feem ntau xa mus rau txhua yam yas tshwj tsis yog rau 1-6. Daim ntawv lo rau lub raj mis yas thiab cov dej xa dej feem ntau yog '7'.
Peb yuav tsum sim kom tsis txhob muaj qhov kub thiab txias, rov siv dua, thiab lwm yam ib puag ncig ib puag ncig thaum siv cov thawv ntim yas, thiab cia siab tias yuav muaj ntau lub thawv ntim khoom zoo thiab noj qab nyob zoo rau yav tom ntej.
