Nrog rau lub caij ntuj sov, txhua yam dej haus rau lub caij muag, ntau tus neeg siv khoom nug: lub raj mis dej haus twg muaj kev nyab xeeb dua? Puas yog tag nrho cov kaus poom muaj BPA?

International Food Packaging Association tus tuav ntaub ntawv, tus kws tshaj lij tiv thaiv ib puag ncig Dong Jinshi hais rau cov neeg sau xov xwm tias cov yas polycarbonate uas muaj bisphenol A tau huv si, tsis yooj yim tawg thiab lwm yam ntxwv. Cov neeg tsim khoom siv nws los ua ntau yam khoom siv, xws li cov tais diav yas, lub raj mis dej, lub raj mis me me, cov kaus poom, thiab lwm yam. Epoxy resins uas muaj bisphenol A feem ntau yog siv rau hauv txheej txheej ntawm cov khoom noj thiab dej haus xws li cov kaus poom thiab cov kaus poom. Yog vim li cas vim li cas lub thawv ntim ntawm cov kaus poom hlau thiab txhuas cov kaus poom muaj bisphenol A yog tias bisphenol A muaj cov txiaj ntsig zoo tiv thaiv corrosion thiab tuaj yeem tiv thaiv cov pa oxygen thiab cov kab mob nkag mus rau hauv lub kaus poom.

Dong Jinshi ceeb toom, tam sim no muaj bisphenol A tsis yog tsuas yog txhuas tuaj yeem cola, nrog rau hlau,aluminium tuaj yeem ntimntawm yim cov khoom muaj nqis poruel, cov txiv hmab txiv ntoo hauv kaus poom thiab lwm yam kuj muaj bisphenol A. Txawm li cas los xij, Dong Jinshi kuj tau taw qhia tias qhov no tsis tau txhais hais tias txhua lub kaus poom muaj BPA, qee cov kaus poom tam sim no yog ua los ntawm cov yas, tsuav yog lawv tsis ua los ntawm PC. yas, lawv tsis muaj BPA.

Bisphenol A, lub npe scientific ntawm 2, 2-di (4-hydroxyphenyl) propane, yog ib qho tseem ceeb ntawm cov organic chemical raw khoom, phenol thiab acetone tseem ceeb derivatives ntawm bisphenol A molecular space filling kab mob, feem ntau yog siv nyob rau hauv zus tau tej cov polycarbonate, epoxy. resin, polysulfone resin, polyphenyl ether resin, unsaturated polyester resin thiab lwm yam ntaub ntawv polymer. Nws tseem tuaj yeem siv rau hauv kev tsim cov yas yas, nplaim hluav taws xob, tshuaj tua kab mob, tshuaj tua kab mob, roj hmab antioxidant, tshuaj tua kab, xim thiab lwm yam khoom zoo.

Cov ntaub ntawv qhia tias bisphenol A yog cov tshuaj lom neeg tsawg. Kev kuaj tsiaj txhu tau pom tias bisphenol A muaj txiaj ntsig ntawm kev ua cov tshuaj estrogen, txawm tias qhov koob tshuaj tsawg heev, nws tuaj yeem ua rau tus tsiaj tsim cov poj niam thaum ntxov maturation, phev suav poob, prostate loj hlob thiab lwm yam teebmeem. Tsis tas li ntawd, nws tau pom tias bisphenol A muaj qee yam embryonic toxicity thiab teratogenicity, uas tuaj yeem ua rau muaj mob qog noj ntshav ntawm zes qe menyuam, mob qog nqaij hlav prostate, leukemia thiab lwm yam qog nqaij hlav hauv tsiaj.

Yuav ua li cas xaiv cov dej haus uas tsis yog bisphenol A

Kev ua lag luam rau bisphenol A tsis tau ploj mus, thiab tej zaum yuav muaj kev phom sij ntawm bisphenol A. Yog li, lub ntim twg yog qhov zoo tshaj plaws ntawm kev ua lag luam? Yuav ua li cas txheeb xyuas cov khoom yas uas muaj bisphenol A?

Thaum xaiv ib lub kaus poom, nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum tau nyeem cov lej hauv daim duab peb sab hauv qab ntawm lub raj mis yas. Vim tias txhua tus lej sawv cev rau cov khoom siv yas, cov khoom sib txawv, kev ua haujlwm sib txawv, kev siv nyab xeeb kuj txawv.

Raws li lub teb chaws tus qauv, "1" stands rau PET (polyethylene terephthalate), uas feem ntau yog siv nyob rau hauv cov ntxhia dej fwj thiab carbonated haus fwj. Thaum tshav kub kub resistant 70 ℃, tsuas yog haum rau chav tsev kub dej qab zib los yog khov dej qab zib, siab kub kua yog ib qho yooj yim deformation, siv sij hawm ntev dua yuav tso cov pa phem; "3" sawv cev rau PVC (7810,15.00,0.19%) (polyvinyl chloride), uas tsis tuaj yeem siv rau hauv ntim khoom noj; "4" sawv cev rau LDPE (tsawg ntom polyethylene), siv rau cling zaj duab xis, yas zaj duab xis, thiab lwm yam, thaum nws ua tau raws li 110 ℃, yuav muaj kub melting tshwm sim, yog li ua ntej siv lub microwave qhov cub, nco ntsoov tshem tawm cov zaub mov cling zaj duab xis. ua ntej; "5" stands rau PP (polypropylene), uas yog siv nyob rau hauv lub microwave noj su thawv thiab yuav tsum tau rhuab; "6" stands rau PS (polystyrene), uas yog siv los ua lub tais ntawm instant noodle thawv thiab cov thawv ntim khoom noj ceev, tab sis nws tsis tuaj yeem ua kom sov hauv qhov cub microwave, thiab nws tsis tuaj yeem siv los thauj cov kua qaub thiab alkaline; Lub "7" sawv cev rau polycarbonate (PC) thiab lwm hom, uas txhais tau hais tias yog tus lej hauv daim duab peb sab yog 7, nws yuav tsum muaj BPA.
