I-Melamine tableware iwuhlobo lwe-tableware enezingozi zokuphepha.Ngenxa yokuthi izithako azifanelekile, i-melamine tableware izohlangabezana nezinkinga.Eqinisweni, i-tableware ye-melamine iyasebenza "Kuzinga Lenhlanzeko Lemikhiqizo Yokwenza I-Melamine-Formaldehyde Yeziqukathi Zokudla Nezinto Zokupakisha".Yiziphi izithako okufanele zilebulwe ku-tableware ye-melamine?
"Amazinga Enhlanzeko Okusetshenziswa Kwezithako Eziqukathi Zokudla kanye Nezinto Zokupakisha" aqaliswe ukusebenza ngo-June 1 2016. Ibeka ukuthiizinto ezingavuthiwe ze-melamine-formaldehyde resin(okungukuthi, i-melamine resin) akufanele ikhulule izinto eziyingozi empilweni ngaphansi kwezimo ezinconyiwe zokusetshenziswa;ekutholeni izinkomba zenhlanzeko zomzimba nezamakhemikhali, Ukunqunywa kwenani lokufuduka kwe-melamine monomer kwandiswa.
Ukuze kufakwe ilebula ye-melamine tableware, iimpahla eluhlaza ye-tablewarekudingeka ngokucacile okokuqala ngqa, futhi "ibanga lokudla" kanye "nokushisa kuhhavini we-microwave okunqatshelwe" kuzokwaziswa.Iphakheji yangaphandle idingeka ngokucacile ukuze imakwe "ibanga lokudla" futhi kubonisiwe umenzi, igama lomkhiqizo, izimo zokusetshenziswa, izinhlobo zezinto, njll.
Ngokwezinga, iyunithi yezinsalela zezinkomba zomzimba namakhemikhali, ukusetshenziswa kwe-potassium permanganate, insimbi enzima, nokufuduka kwe-formaldehyde monomer kwabuyekezwa kusukela ku-ra9/L (mg/L) kuya ku-m9/dm2 (mg/dm2).Ochwepheshe baveze ukuthi leli zinga lilingana no-15m9/L, eliqine ngokuphindwe kabili kunelokuqala elijwayelekile elingu-30m9/L.I-resin ye-Urea-formaldehyde kusiphithiphithi "sesidlo esinjenge-porcelain enobuthi" esithole ukunakwa okuningi ngaphambili, ochwepheshe bathi lezi zindinganiso ezimbili ezingenhla azifakiwe kububanzi bokusetshenziswa.
Kodwa-ke, i-China Plastics Processing Industry Association ibambe isithangami sabezindaba muva nje, ithi i-uremic resin-coated melamine resin tableware nayo iphephile, futhi yacela umbuso ukuthi uthuthukise izindinganiso ezifanele.
