Kodi Melamine Ndi Chiyani Kuti Mugwiritse Ntchito Mu Dishware? - Thanzi

Zamkati

Melamine ndi mankhwala opangidwa ndi nayitrogeni omwe opanga ambiri amapanga kuti apange zinthu zingapo, makamaka mbale za pulasitiki. Amagwiritsidwanso ntchito mu:

  • ziwiya
  • malo owerengera
  • mankhwala pulasitiki
  • matabwa owuma
  • mankhwala pepala

Ngakhale melamine imapezeka kwambiri m'zinthu zambiri, anthu ena afotokoza nkhawa zakuti mankhwalawa akhoza kukhala owopsa.

Nkhaniyi ifufuza zotsutsana komanso malingaliro okhudzana ndi melamine muzinthu zapulasitiki. Pitilizani kuwerenga kuti mupeze ngati mbale za melamine ziyenera kukhala ndi malo mu makabati anu komanso muma picnic anu.

Kodi ndizotetezeka?

Yankho lalifupi ndilo inde, ndizotetezeka.

Pamene opanga amapanga mapulogalamu apulasitiki okhala ndi melamine, amagwiritsa ntchito kutentha kwambiri kuti awumbe zinthuzo.

Pomwe kutentha kumagwiritsa ntchito mankhwala ambiri a melamine, pang'ono zokha zimatsalira m'm mbale, kapu, ziwiya kapena zina zambiri. Ngati melamine yatentha kwambiri, imatha kusungunuka ndipo imatha kutayikira muzakudya ndi zakumwa.


Kuda nkhawa

Chidwi chachitetezo ndikuti melamine imatha kuchoka pama mbale kupita kuzakudya ndikupangitsa kuti idye mwangozi.

Wachita kuyesa zachitetezo pazinthu za melamine. Zitsanzo zimaphatikizapo kuyeza kuchuluka kwa melamine yomwe idalowetsedwa mu zakudya pamene melamine imasungidwa kutentha kwambiri motsutsana ndi zakudya kwa maola angapo.

A FDA adapeza kuti zakudya za acidic, monga madzi a lalanje kapena zopangidwa ndi phwetekere, zimakonda kukhala ndi melamine yosunthira kwambiri kuposa nonacidic.

Zotsatira

Komabe, kuchuluka kwa melamine yomwe ikudontha kumawerengedwa kuti ndi kocheperako - pafupifupi 250 kutsika kuposa mulingo wa melamine omwe a FDA amawona kuti ndi owopsa.

A FDA atsimikiza kuti kugwiritsa ntchito mapepala apulasitiki, kuphatikiza omwe ali ndi melamine, ndibwino kugwiritsa ntchito. Adakhazikitsa kudya kwama tsiku ndi tsiku mamiligalamu 0,063 pa kilogalamu ya kulemera kwa thupi patsiku.

A FDA amachenjeza anthu kuti asayike mbale zapulasitiki zama microwave zomwe sizitchulidwa kuti "zotetezedwa ndi ma microwave." Zinthu zotetezedwa ndi ma microwave nthawi zambiri zimapangidwa kuchokera kuzinthu za ceramic, osati melamine.


Komabe, mutha kuyika ma microwave kena kake pa mbale yotetezedwa ndi ma microwave ndikuyigwiritsa ntchito mbale ya melamine.

Kodi pali zoopsa zilizonse kapena zoyipa zilizonse?

Chodetsa nkhaŵa chachikulu chokhudza melamine ndichakuti munthu amatha kupwetekedwa ndi melamine poyambira ndikudya.

Kafukufuku wocheperako wa 2013 wofalitsidwa mwa odzipereka omwe ali ndi thanzi 16 kuti adye msuzi wotentha womwe umakhala mu mbale za melamine. Ofufuzawo adatenga zitsanzo za mkodzo kuchokera kwa omwe adatenga nawo gawo maola awiri aliwonse kwa maola 12 atadya msuzi.

Ofufuzawo adapeza melamine mumkodzo wa omwe akutenga nawo mbali, akuwonjezeka pakati pa 4 mpaka 6 maola atangoyamba kudya msuzi.

Pomwe ofufuzawo adazindikira kuti melamine imatha kusiyanasiyana kutengera wopanga mbale, adatha kuzindikira melamine kuchokera mumsuzi.

Adatenga zitsanzo asanadye msuzi kuti awonetsetse kuti omwe akutenga nawo gawo alibe melamine mkodzo wawo asanayambe kuphunzira. Olemba kafukufukuyu adatsimikiza kuthekera kwakukuvulazidwa kwakanthawi kuchokera pakuwonekera kwa melamine "kuyenerabe kukhala kofunika."


Ngati munthu atha kudya milamine yambiri, atha kukhala pachiwopsezo cha impso, kuphatikiza impso kapena kulephera kwa impso. Malinga ndi nkhani yolembedwa ndi International Journal of Food Contamination, kuchepa kwa melamine nthawi zonse kumatha kukhala kokhudzana ndi chiwopsezo cha miyala ya impso mwa ana ndi akulu.

Chimodzi mwazovuta zina zokhudzana ndi poizoni wa melamine ndikuti madotolo samadziwa bwino zomwe zimachitika pakutha kwa melamine. Kafukufuku waposachedwa kwambiri amachokera ku maphunziro azinyama. Amadziwa kuti zizindikiro zakupha kwa melamine ndi monga:

  • magazi mkodzo
  • kupweteka m'mbali mwake
  • kuthamanga kwa magazi
  • kupsa mtima
  • kupanga mkodzo pang'ono
  • kufunika kokodza mwachangu

Ngati muli ndi zizindikirozi, ndikofunikira kuti mupite kuchipatala mwachangu.

Mavuto ena a melamine

Mitundu ina ya kuipitsa kwa melamine, kupatula kugwiritsa ntchito tableware, yakhala ikunenedwa.

Mu 2008, akuluakulu aku China adati ana akhanda adadwala chifukwa chowonekera melamine mosavomerezeka akuwonjezera mkaka. Opanga zakudya anali kuwonjezera melamine kuti apange ma protein okhala mkaka.

Chochitika china chidachitika mu 2007 pomwe chakudya cha ziweto zochokera ku China, komabe chimagawidwa ku North America, chinali ndi milamine yambiri. N'zomvetsa chisoni kuti izi zinachititsa kuti ziweto zoposa 1,000 zizifa. Kukumbukira zakumwa zopitilira 60 za agalu kunachitika.

FDA siyilola melamine ngati chowonjezera pa chakudya kapena kuti agwiritse ntchito ngati feteleza kapena mankhwala ophera tizilombo.

Ubwino ndi kuipa

Tengani maubwino ndi zoyipa izi musanagwiritse ntchito mbale ya melamine kuti muone ngati ndiyabwino kwa inu.

Ubwino wa Melamine

  • ochapa chotsuka-otetezeka
  • cholimba
  • zobwezerezedwanso
  • kawirikawiri amakhala otsika mtengo

Mavuto a Melamine

  • osagwiritsidwa ntchito mu microwave
  • Kuthekera kwakubwera chifukwa chakuwonekera pafupipafupi

Njira zina zotengera melamine

Ngati simukufuna kupitiliza kugwiritsa ntchito mbale kapena ziwiya za melamine, pali njira zina. Zitsanzo ndi izi:

  • mbale zadothi
  • mbale za enamel
  • muli galasi
  • nsungwi zopangidwa ndi nsungwi (osati zotetezedwa ndi mayikirowevu)
  • miphika ndi ziwaya zosalumikiza
  • mbale zosapanga dzimbiri (osati zotetezera ma microwave)

Opanga amatchula zambiri mwazinthuzi ngati zopanda melamine kapena pulasitiki, zomwe zimapangitsa kuti zikhale zosavuta kugula ndi kupeza.

Mfundo yofunika

Melamine ndi mtundu wa pulasitiki womwe umapezeka m'mbale zambiri, ziwiya, ndi makapu. A FDA agamula kuti melamine ndiyabwino kugwiritsa ntchito, koma kuti simuyenera kuyigwiritsa ntchito mu microwave.

Komabe, ngati mukuda nkhawa ndi kutulutsa kwa melamine kuchokera m'mbale, pali njira zina kunja uko.
