Zvishongo zveMelamine zvakagadzirwa nehupfu hwemelamine resin nekudziisa uye kudiridza. Zvichienderana nehuwandu hwezvinhu zvakagadziriswa, zvikamu zvikuru zvaro zvakakamurwa kuita zvikamu zvitatu, A1, A3 neA5.
Chinhu cheA1 melamine chine 30% melamine resin, uye 70% yezvinhu zvinoshandiswa zvinowedzera, starch, nezvimwewo. Kunyangwe zvikafu zvakagadzirwa nerudzi urwu rwezvinhu zvisina kugadzirwa zvine huwandu hwakati hwemelamine, ine hunhu hwepurasitiki, haipindi kupisa kwakanyanya, iri nyore kukanganisika, uye haina kupenya kwakawanda. Asi mutengo unoenderana wakaderera, chigadzirwa chemhando yepamusoro, chakakodzera Mexico, Africa nedzimwe nzvimbo.
Chinhu cheA3 melamine chine 70% melamine resin, uye chimwe 30% chinowedzera, starch, nezvimwewo. Ruvara rwechitarisiko chemidziyo yakagadzirwa neA3 haruna kusiyana zvakanyanya nerweA5. Vanhu vangasakwanisa kusiyanisa pakutanga, asi kana midziyo yakagadzirwa neA3 yashandiswa, zviri nyore kuchinja ruvara, kupera uye kukanganisika kana yapisa zvakanyanya mushure menguva yakareba. Zvinhu zveA3 zvakachipa pane zveA5. Mamwe mabhizinesi anozviti A5 seA3, uye vatengi vanofanira kusimbisa chinhu chacho pavanenge vachitenga midziyo.
Chinhu cheA5 melamine chine resin ye100%, uye midziyo yekubikira inogadzirwa neA5 raw material ndeye tableware yeA5 chaiyo. Hunhu hwayo hwakanaka kwazvo, hahuna chepfu, hahuna kunaka, huri nyore uye hunochengetedza kupisa. Ine kupenya kwakafanana neceramics, asi inonzwa zviri nani pane ceramics dzakajairika.
Uye kusiyana neceramics, inopfava uye inorema, saka haina kukodzera vana. Melamine tableware haidonhe, haipfava, uye ine chitarisiko chakanaka. Tembiricha yakakodzera yemelamine tableware iri pakati pe -30 degrees Celsius ne120 degrees Celsius, saka inoshandiswa zvakanyanya mukubika uye muhupenyu hwezuva nezuva.
