Melamine tableware yog ib yam ntawm cov tais diav uas muaj kev nyab xeeb.Vim tias cov khoom xyaw tsis tsim nyog, melamine tableware yuav ntsib teeb meem.Qhov tseeb, melamine tableware muaj feem xyuam rau "Sanitary Standard for Melamine-Formaldehyde Forming Products for Food Containers and Packaging Materials".Cov khoom xyaw twg yuav tsum tau sau rau ntawm melamine tableware?
"Cov qauv kev huv huv rau kev siv cov khoom siv ntxiv rau cov ntim khoom noj thiab cov khoom ntim" tau raug coj los siv rau lub Rau Hli 1 2016. Nws tau hais tias covraw khoom melamine-formaldehyde resin(xws li, melamine resin) yuav tsum tsis txhob tso cov tshuaj phem rau kev noj qab haus huv raws li kev pom zoo ntawm kev siv;Nyob rau hauv kev tshawb pom ntawm kev huv lub cev thiab tshuaj ntsuas ntsuas, qhov kev txiav txim siab ntawm kev tsiv teb tsaws ntawm melamine monomer tau nce.
Rau daim ntawv lo ntawm melamine tableware, lubraw khoom ntawm tablewareNws yog qhov yuav tsum tau ua kom pom tseeb rau thawj zaug, thiab "qib zaub mov" thiab "cua sov hauv microwave qhov cub txwv tsis pub" yuav tsum tau ceeb toom.Lub ntim sab nrauv yog qhov yuav tsum tau ua kom pom tseeb tias yuav tsum tau cim nrog "qib zaub mov" thiab cov chaw tsim khoom, lub npe khoom, kev siv, hom khoom, thiab lwm yam tau qhia.
Nyob rau hauv tus qauv, chav tsev ntawm lub cev thiab tshuaj ntsuas evaporation residue, poov tshuaj permanganate noj, hnyav hlau, thiab formaldehyde monomer tsiv teb tsaws raug kho los ntawm ra9/L (mg/L) rau m9/dm2 (mg/dm2).Cov kws tshaj lij tau taw qhia tias tus qauv no yog sib npaug rau 15m9 / L, uas yog ob zaug nruj raws li tus qauv qub 30m9 / L.Urea-formaldehyde resin nyob rau hauv "tshuaj lom porcelain-zoo li pluas noj" kev ntxhov siab uas tau txais kev saib xyuas ntau ua ntej, cov kws tshaj lij tau hais tias ob qho qauv saum toj no tsis suav nrog qhov kev siv.
Txawm li cas los xij, Tuam Tshoj Plastics Processing Industry Association tau tshaj tawm xov xwm tsis ntev los no, hais tias uremic resin-coated melamine resin tableware kuj muaj kev nyab xeeb, thiab tau thov kom lub xeev tsim cov qauv tsim nyog.
