Kwixesha elidlulileyo, izitya ze-melamine bezisoloko ziphandwa kwaye ziphuculwa, kwaye abantu abaninzi bayayisebenzisa. Isetyenziswa kakhulu kwiihotele, kwiindawo zokutyela zokutya okukhawulezayo, kwiivenkile zeedizethi nakwezinye iindawo. Nangona kunjalo, abanye abantu bayathandabuza malunga nokhuseleko lwezitya ze-melamine. Ngaba iplastiki yezitya ze-melamine inetyhefu? Ngaba iya kuba yingozi emzimbeni womntu? Le ngxaki iya kucaciswa kuwe ziingcali zomenzi wezitya ze-melamine.
Izitya zeMelamine zenziwe ngomgubo we-melamine resin ngokufudumeza nangokucinezela. Umgubo weMelamine wenziwe nge-melamine formaldehyde resin, ekwaluhlobo lweplastiki. Yenziwe nge-cellulose njengesixhobo esisisiseko, yongeza imibala kunye nezinye izongezo. Ngenxa yokuba inesakhiwo senethiwekhi esinemilinganiselo emithathu, sisixhobo se-thermoset. Ukuba nje izitya zeMelamine zisetyenziswa ngokufanelekileyo, aziyi kuvelisa naziphi na iityhefu okanye umonakalo emzimbeni womntu. Ayinazo izinto zesinyithi esinzima, kwaye ayizukubangela ubuthi besinyithi emzimbeni womntu, kwaye ayizukubangela impembelelo ethile embi kuphuhliso lwabantwana njengokusetyenziswa kwexesha elide kwefoyile ye-aluminium ekutyeni kwiimveliso ze-aluminium.
Ngenxa yokunyuka kwexabiso le-melamine powder, abanye abathengisi abangathembekanga basebenzisa ngokuthe ngqo i-urea-formaldehyde molding powder njengezinto zokwenza inzuzo; umphezulu wangaphandle ugqunywe ngumaleko we-melamine powder. Izitya ezenziwe nge-urea-formaldehyde ziyingozi emzimbeni womntu. Yingakho abanye abantu becinga ukuba izitya ze-melamine ziyingozi.
Xa abathengi bethenga, kufuneka baqale baye evenkileni eqhelekileyo okanye kwivenkile enkulu. Xa bethenga, jonga ukuba ingaba izitya zetafile zinokuguquguquka okucacileyo, umahluko wombala, umphezulu ogudileyo, ezantsi, njl. Nokuba azilingani kwaye ingaba ipateni yeapplique icacile na. Xa izitya zetafile ezinemibala zisulwa ngapha nangapha ngama-napkin amhlophe, nokuba kukho na into efana nokufiphala. Ngenxa yenkqubo yokuvelisa, ukuba idecal inomphetho othile, kuyinto eqhelekileyo, kodwa xa umbala ufiphala, zama ukungayithengi.
