Melamine tableware ndi mtundu wa tableware wokhala ndi zoopsa zachitetezo.Chifukwa zosakanizazo ndi zosayenera, melamine tableware idzakumana ndi mavuto.M'malo mwake, tableware ya melamine imagwira ntchito ku "Sanitary Standard for Melamine-Formaldehyde Forming Products for Food Containers and Packaging Equipment".Ndi zinthu ziti zomwe ziyenera kulembedwa pa melamine tableware?
Miyezo ya "Sanitary Standards for Use of Additives for Food Containers and Packaging Materials" idakhazikitsidwa pa June 1 2016.zopangira melamine-formaldehyde utomoni(ndiko, utomoni wa melamine) sayenera kutulutsa zinthu zovulaza thanzi pansi pamikhalidwe yoyenera kugwiritsidwa ntchito;pozindikira ukhondo thupi ndi mankhwala zizindikiro, Kutsimikiza kwa kusamuka kuchuluka kwa melamine monoma chinawonjezeka.
Pazolemba za melamine tableware, thezopangira za tablewarezimafunika momveka bwino kwa nthawi yoyamba, ndipo "kalasi ya chakudya" ndi "kuwotcha mu uvuni wa microwave woletsedwa" ziyenera kudziwitsidwa.Kupaka kwakunja kumafunikanso kuzindikirika ndi "kalasi yazakudya" ndipo wopanga, dzina lazogulitsa, mikhalidwe yogwiritsira ntchito, mitundu yazinthu, ndi zina zikuwonetsedwa.
Mu muyezo, gawo la zotsalira za thupi ndi mankhwala zotsalira za evaporation, kumwa kwa potaziyamu permanganate, heavy metal, ndi kusamuka kwa formaldehyde monomer zidasinthidwanso kuchokera ku ra9/L (mg/L) mpaka m9/dm2 (mg/dm2).Akatswiri adanenanso kuti mulingo uwu ndi wofanana ndi 15m9/L, womwe ndi wokhwima kuwirikiza kawiri kuposa wa 30m9/L woyambirira.Urea-formaldehyde utomoni mu "poizoni zadothi ngati chakudya" chipwirikiti chipwirikiti analandira chidwi kwambiri kale, akatswiri ananena kuti mfundo ziwiri pamwambazi sizikuphatikizidwa mu kukula kwa ntchito.
Komabe, China Plastics Processing Industry Association idachita msonkhano wa atolankhani posachedwapa, ponena kuti uremic resin- TACHIMATA melamine resin tableware ndi otetezeka, ndipo anapempha boma kukhazikitsa mfundo zoyenera.
