Melamine tableware imhando yetafuraware ine njodzi dzekuchengetedza.Nekuti izvo zvinongedzo hazvina kukodzera, melamine tableware ichasangana nematambudziko.Muchokwadi, iyo melamine tableware inoshanda kune "Sanitary Standard yeMelamine-Formaldehyde Kugadzira Zvigadzirwa zveChikafu Container uye Packaging Zvishandiso".Ndezvipi zvinhu zvinofanira kunyorwa pa melamine tableware?
Iyo "Sanitary Standards yeKushandisa Additives yeChikafu Containers uye Packaging Materials" yakange yaitwa muna Chikumi 1 2016. Inoti iyoraw material melamine-formaldehyde resin(kureva, melamine resin) haifanire kuburitsa zvinhu zvinokuvadza kune hutano pasi pemamiriro akakurudzirwa ekushandisa;mukuonekwa kwehutsanana hwemuviri uye makemikari zviratidzo, Iko kutsunga kwehuwandu hwekufamba kwemelamine monomer hwakawedzerwa.
Nekunyorwa kwe melamine tableware, iyoraw material ye tablewareinonyatso kudiwa kwekutanga, uye "giredhi yezvokudya" uye "kupisa muvheni yewa microwave inorambidzwa" inofanira kuziviswa.Iyo yekurongedza yekunze inonyanya kudiwa kuti icherechedzwe ne "giredhi rekudya" uye mugadziri, zita rechigadzirwa, mamiriro ekushandiswa, marudzi ezvigadzirwa, nezvimwe zvinoratidzwa.
Muchiyero, chikamu chemuviri uye chemakemikari zvinoratidzira evaporation zvakasara, potassium permanganate kushandiswa, heavy metal, uye formaldehyde monomer migration yakadzokororwa kubva para9/L (mg/L) kusvika m9/dm2 (mg/dm2).Nyanzvi dzakaratidza kuti chiyero ichi chakaenzana ne15m9/L, iyo yakapetwa kaviri seyakatanga chiyero 30m9/L.Urea-formaldehyde resin mune "chepfu porcelain-yakafanana chikafu" mhirizhonga yakagamuchirwa zvakanyanya kare, nyanzvi dzakataura kuti zviyero zviviri zviri pamusoro hazvina kubatanidzwa muchikamu chekushandiswa.
Nekudaro, iyo China Plastics Processing Industry Association yakaita musangano nevatori venhau nguva pfupi yadarika, ichiti uremic resin-yakavharidzirwa melamine resin tableware yakachengeteka, uye yakadana nyika kuti igadzirise zviyero zvakakodzera.
