Ibikoresho bya Melamine ni ubwoko bwibikoresho byo kumeza bifite ingaruka mbi kumutekano.Kuberako ibiyigize bitujuje ibyangombwa, melamine ibikoresho byo kumeza bizahura nibibazo.Mubyukuri, ibikoresho byo kumeza ya melamine birakoreshwa kuri "Isuku yisuku ya Melamine-Formaldehyde ikora ibicuruzwa kubikoresho birimo ibiryo nibikoresho byo gupakira".Nibihe bintu bigomba gushyirwaho ikimenyetso cya melamine?
"Ibipimo by'isuku byo gukoresha inyongeramusaruro y'ibikoresho n'ibikoresho byo gupakira" byari byashyizwe mu bikorwa ku ya 1 Kamena 2016. Biteganya koibikoresho fatizo melamine-formaldehyde resin(aribyo, melamine resin) ntigomba kurekura ibintu byangiza ubuzima mugihe cyagenwe cyo gukoresha;mugushakisha ibipimo byisuku byumubiri nubumara, Kugena umubare wimuka wa melamine monomer wariyongereye.
Kubirango bya melamine kumeza, theibikoresho fatizo byo kumezabirasabwa neza kunshuro yambere, kandi "urwego rwibiryo" na "gushyushya mu ziko rya microwave birabujijwe" bigomba kumenyeshwa.Ibipfunyika byo hanze birasabwa cyane gushyirwaho ikimenyetso cy "ibiryo" kandi uwabikoze, izina ryibicuruzwa, imiterere yimikoreshereze, ubwoko bwibikoresho, nibindi byerekanwe.
Mubisanzwe, igice cyerekana ibipimo byumubiri nubumara ibisigazwa byuka, ikoreshwa rya potasiyumu permanganate, ibyuma biremereye, hamwe na formaldehyde monomer yimuka byavuguruwe kuva ra9 / L (mg / L) kugeza m9 / dm2 (mg / dm2).Abahanga bagaragaje ko iki gipimo gihwanye na 15m9 / L, ikaba ikubye kabiri igipimo cyambere 30m9 / L.Urea-formaldehyde isubira mu gihirahiro cy '"uburozi bwa farashi isa n’uburozi" bwitabiriwe cyane mbere, abahanga bavuze ko ibipimo bibiri byavuzwe haruguru bitashyizwe mu rwego rwo gukoresha.
Icyakora, Ishyirahamwe ry’inganda zitunganya plastike mu Bushinwa ryagiranye ikiganiro n’abanyamakuru vuba aha, rivuga ko ibikoresho byo mu bwoko bwa uremic bisizwe na melamine resin byo mu meza nabyo bifite umutekano, anasaba leta gushyiraho ibipimo bifatika.
