Izitsha zokudla ze-Melamine zenziwe ngempuphu ye-melamine resin ngokushisa nangokuyiphonsa ngomshini wokushisa. Ngokwesilinganiso sezinto zokusetshenziswa, izigaba zayo eziyinhloko zihlukaniswe ngamagremu amathathu, i-A1, i-A3 kanye ne-A5.
Izinto ze-melamine ze-A1 ziqukethe i-30% ye-melamine resin, kanti u-70% wezithako ziyizithasiselo, isitashi, njll. Nakuba izitsha zokudla ezikhiqizwa ngalolu hlobo lwezinto zokusetshenziswa ziqukethe inani elithile le-melamine, zinezici zepulasitiki, azimelani nokushisa okuphezulu, kulula ukuzishintsha, futhi zicwebezela kabi. Kodwa intengo ehambisanayo iphansi impela, ingumkhiqizo osezingeni eliphansi, ofanelekela iMexico, i-Afrika nezinye izifunda.
Izinto ze-melamine ze-A3 ziqukethe i-melamine resin engu-70%, kanti ezinye ezingu-30% ziyizithasiselo, isitashi, njll. Umbala wokubukeka kwezitsha ezenziwe ngezinto ze-A3 awuhlukile kakhulu kowezinto ze-A5. Abantu bangase bangakwazi ukuwuhlukanisa ekuqaleni, kodwa uma izitsha ezenziwe ngezinto ze-A3 sezisetshenzisiwe, kulula ukushintsha umbala, ukufiphala nokuguquguquka ngaphansi kokushisa okuphezulu ngemva kwesikhathi eside. Izinto zokusetshenziswa ze-A3 zishibhile kuneze-A5. Amanye amabhizinisi azokwenza sengathi yi-A5 njenge-A3, futhi abathengi kumele baqinisekise izinto lapho bethenga izitsha.
Izinto ze-melamine ze-A5 ziyi-resin ye-melamine engu-100%, kanti izinto zokupheka ezikhiqizwa ngezinto zokupheka ze-A5 ziyizinto zokupheka ze-melamine ezihlanzekile. Izici zazo zinhle kakhulu, azinabo ubuthi, azinambitheki, zilula futhi zigcinwa zishisa. Zinokukhanya okufana nokwezinto zokupheka, kodwa zizizwa zingcono kunezinto zokupheka ezivamile.
Futhi ngokungafani nezinto zobumba, iyaphuka futhi iyasinda, ngakho ayifanele izingane. Izitsha zetafula ze-Melamine ziyamelana nokuwa, aziphuki kalula, futhi zibukeka kahle kakhulu. Izinga lokushisa elifanele lezitsha zetafula ze-melamine liphakathi kwama-degree Celsius angu-30 kanye nama-degree Celsius angu-120, ngakho-ke lisetshenziswa kabanzi ekuphekeni nasekuphileni kwansuku zonke.
