Cov thawv yas tam sim no tau siv dav hauv txhua yam ntawm peb lub neej, vim nws siv tau dav heev, feem ntau, nws tau raug sim thiab pom zoo.
Tab sis qhov tseem ceeb yog tseem saib cov qeb twg yog "yas". Vim hais tias yas yog ib lo lus dav heev.
Muaj ib txoj hauv kev yooj yim, koj saib cov thawv yas muaj ib daim npav ID me me - daim duab peb sab, feem ntau nyob hauv qab ntawm cov thawv yas. Muaj 1 txog 7 tus lej hauv daim duab peb sab, txhua tus lej sawv cev rau lub thawv yas, lawv cov khoom sib txawv, kev siv cov contraindications kuj txawv.
Nws yuav tsum raug sau tseg tias, tsis muaj daim npav ID me me no, nws tau pom zoo kom tsis txhob siv, lossis ceev faj ntawm cov tuam txhab lag luam dub.
Tsis nkag siab koj tus cwj pwm tsis zoo los teb, tab sis koj tuaj yeem xa mus rau cov ntaub ntawv hauv qab no. Yog tias tub nkeeg dhau los saib, lossis nrog lub khob ntawm stainless hlau khob.
Yas lub npe -------- Code thiab cov lej sib raug zoo yog raws li hauv qab no:
Polyester --- 01-PET (PET lub raj mis)
High-density polyethylene - 02-HDPE
PVC ---- 03-PVC
Tsawg-density polyethylene - 04-LDPE
Polypropylene ----- 05-PP (kub ntawm ntau tshaj 100 degrees)
Polystyrene ---- 06-PS (kub 60-70} degrees, dej kub yuav tsim co toxins, hlawv yuav tso cov styrene)
Lwm cov lej yas - 07-Lwm yam
"No. 1" PET: lub raj mis dej ntxhia, carbonated haus fwj
Haus fwj tsis siv lub voj voog dej kub
Siv: cua sov rau 70 degree, tsuas yog haum rau cov dej qab zib sov los yog cov dej khov khov, ntim nrog cov kua kub kub, lossis yooj yim rau deformation thaum rhuab, muaj cov khoom tsis zoo. Thiab, cov kws tshawb fawb pom tau tias No.
Yog li ntawd, lub raj mis thiab lwm yam dej qab zib raug muab pov tseg thaum lawv siv tas. Lawv yuav tsum tsis txhob siv rau lub khob haus lossis lwm lub thawv ntim khoom kom tsis txhob muaj teeb meem kev noj qab haus huv.
"No. 2" HDPE: cov khoom siv tu, cov khoom siv da dej
Tsis tau ntxuav kom huv si pom zoo kom tsis txhob rov ua dua
Siv: tuaj yeem rov siv dua tom qab ua tib zoo tu, tab sis cov thawv no feem ntau tsis zoo rau kev ntxuav, tawm hauv cov khoom siv tu thawj, ua cov kab mob kub, nws yog qhov zoo tshaj kom tsis txhob rov ua dua.
"No. 3" PVC: Tam sim no tsis tshua muaj siv hauv ntim khoom noj
Nws yog qhov zoo tshaj kom tsis txhob yuav
Siv: Cov khoom siv no yog cov khoom siv phom sij ntawm qhov kub thiab txias, txawm tias thaum lub sijhawm tsim khoom nws yuav tso cov tshuaj lom nrog cov zaub mov rau hauv lub cev, tuaj yeem ua rau mob qog noj ntshav, yug me nyuam thiab lwm yam kab mob. Tam sim no, ntim cov khoom siv no tau siv tsawg dua rau kev ntim khoom noj. Yog siv, tsis txhob cia nws sov.
"4" LDPE: yas qhwv, yas zaj duab xis thiab lwm yam
Cling zaj duab xis qhwv hauv cov zaub mov saum npoo rau hauv lub qhov cub microwave
Siv: Thaum tshav kub kub tsis muaj zog, feem ntau, tsim nyog PE cling zaj duab xis nyob rau hauv cov ntaub ntawv ntawm kub tshaj 110 degree yuav tshwm sim kub yaj tshwm sim, yuav tawm hauv ib co lub cev tsis tuaj yeem zom cov yas npaj. Thiab, qhwv cov zaub mov nrog cov yas qhwv cua sov, cov roj zaub mov yooj yim kom yaj cov khoom tsis zoo hauv cov yas qhwv tawm. Yog li ntawd, cov khoom noj rau hauv lub qhov cub microwave, koj yuav tsum xub tshem tawm cov hnab yas qhwv.
"No. 5" PP: microwave noj lub thawv
Tshem lub hau thaum nyob hauv lub microwave
Siv: Tsuas yog lub thawv yas uas tuaj yeem muab tso rau hauv lub qhov cub microwave kom rov siv dua tom qab ua tib zoo tu. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qee lub thawv noj su hauv microwave. Lub thawv yog ua los ntawm PP No. 5, tab sis lub hau yog ua los ntawm No. 1 PE. Vim tias PE tsis tuaj yeem tiv taus qhov kub thiab txias, nws tsis tuaj yeem muab tso rau hauv qhov cub microwave ua ke nrog lub thawv. Yuav kom nyob rau sab nyab xeeb, tshem lub hau ua ntej muab lub ntim rau hauv lub microwave.
"6" PS: lub tais ntim cov noodles ntim, ntim khoom noj ceev
Tsis txhob noj nyob rau hauv ib lub tais microwave ntawm instant noodles
Siv: Kuj kub-resistant thiab txias-resistant, tab sis tsis tuaj yeem muab tso rau hauv lub microwave, kom tsis txhob tso cov tshuaj vim qhov kub thiab txias. Thiab tsis tuaj yeem siv los noj cov kua qaub uas muaj zog (xws li kua txiv kab ntxwv), muaj zog alkaline tshuaj, vim nws yuav ua rau tib neeg lub cev tsis zoo rau polystyrene, carcinogenic. Yog li ntawd, koj yuav tsum tau sim kom tsis txhob siv cov khoom noj ceev ceev ntim cov zaub mov kub.
"7" PC Lwm pawg: lub raj mis dej, khob, lub raj mis
PC nplaum kub tso tawm bisphenol A
Siv: Cov khoom siv dav dav, tshwj xeeb tshaj yog siv rau hauv cov me nyuam lub raj mis, muaj kev tsis sib haum xeeb vim nws muaj BPA. Lin Han-hua, tus kws tshaj lij ntawm biology thiab chemistry ntawm City University of Hong Kong, tau hais tias txoj kev xav, tsuav yog bisphenol A hloov mus rau hauv cov qauv yas 100% ntawm lub sijhawm ntawm kev tsim lub PC, nws txhais tau tias. tsis muaj bisphenol A hauv cov khoom, cia nyob ib leeg. Txawm li cas los xij, yog tias ib qho me me ntawm bisphenol A tsis hloov mus rau hauv cov qauv yas ntawm PC, nws yuav raug tso tawm rau hauv cov zaub mov lossis dej haus. Yog li ntawd, ceev faj thaum siv lub thawv yas no yuav tsum tau saib xyuas tshwj xeeb.
Ua tib zoo saib xyuas cov tshuaj bisphenol A
PC residual bisphenol A, qhov kub thiab txias, qhov tso tawm ntau dua, qhov nrawm dua. Yog li ntawd, PC dej fwj yuav tsum tsis txhob ntim nrog dej kub, thiaj li tsis mus nce bisphenol A (yog tias muaj) tso tawm tus nqi thiab concentration. Yog tias koj lub raj mis muaj 7, cov hauv qab no tuaj yeem txo qhov kev pheej hmoo:
● Tsis txhob siv thaum cua sov.
● Tsis muaj lub tshuab ntxuav tais diav, lub tshuab ntxuav tais diav los ntxuav lub hwj.
● Tsis txhob tso cai rau lub raj mis kom raug tshav ntuj ncaj qha.
● Ua ntej siv thawj zaug, yaug nrog baking soda thiab dej sov ntawm chav tsev kub. Vim tias bisphenol A yuav tso tawm ntau dua hauv kev siv thawj zaug thiab siv mus ntev.
● Yog tias ib lub thawv twg puas los yog puas lawm, nws raug nquahu kom tsis txhob siv vim tias cov khoom yas yog qhov yooj yim los nkaum yog tias muaj cov grooves zoo rau ntawm qhov chaw.
● Tsis txhob rov siv cov khoom siv yas laus dua.
