I-Melamine formaldehyde resin (MF)iyinhlaka eyakhiwe yi-polycondensation ye-melamine ne-formaldehyde njengezinto zokusetshenziswa eziyinhloko ngemva kokusabela kwe-hydroxylation.
I-MF isetshenziswe kabanzi ku-kitchenware, amathoyizi, izidingo zansuku zonke, izingxenye zikagesi nezinye izinkambungenxa yezinzuzo zayo zokucubungula nokubumba kalula, ukunemba okuphezulu kwe-dimensional, amandla amahle emishini, ukumelana nokushisa, ukubuyiswa komlilo, ukufakwa kwe-insulation, nokumelana nokugqwala.
Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuqwashisa okwandayo kokuvikelwa kwemvelo, amazwe emhlabeni jikelele asebenzise izinyathelo ezinjengokuvinjelwa kokugawulwa kwehlathi emvelo kanye nezitsha ezilahlwayo ezivinjelwe, ezikhuthaze isidingo semikhiqizo ye-melamine ezimakethe zasekhaya nezangaphandle ukuze kwandiswe. unyaka nonyaka.Kodwa-ke, izindleko zokukhiqizwa kwemikhiqizo ye-melamine formaldehyde resin ehlanzekile ziphakeme kancane, ezikhawulela ukukhuthazwa nokusetshenziswa kwayo ngezinga elithile.Ngakho-ke, i-melamine tableware ene-bamboo powder esanda kuthuthukiswa embonini ye-melamine njengesigcwalisi isithandwa kakhulu.Ngakolunye uhlangothi, ukusetshenziswa kwe-bamboo powder kunganciphisa ngempumelelo izindleko zemikhiqizo yepulasitiki ye-melamine, futhi ngakolunye uhlangothi, kungandisa amandla omthelela we-resin.
Ngaphansi kwezimo ezijwayelekile, izinto zokusetshenziswa ze-melamine bamboo tableware cishe zingama-20% uqalo powder, 60% -70%inhlanganisela ye-melamine, kanti okunye kuyimibala nezigcwalisi.Abanye abathengisi emakethe bazokhuthaza ukuthi i-bamboo melamine tableware ihambisana nemvelo futhi iyabola, kodwa empeleni yimpushana yoqalo kuphela eyonakalayo.Ngakho-ke, kuyadingeka ukuthi abakhiqizi be-tableware bafunde ulwazi lobungcweti lwe-melamine bamboo tableware ukuze umphakathi ube nokuqonda okufanele ngakho.
Amakhemikhali e-Huafuizoqhubeka nokwabelana ngobungcweti obuningi nolwazi oluhlobene nemboni ye-melamine esikhathini esizayo.
