Izolo nje, ngibone isihloko esikhuluma ngezingozi zezitsha ezenziwe nge-melamine, ezaziwa nangokuthi i-melamine. Ngenxa yokuthi i-melamine iqukethe inani elikhulu le-melamine, i-formaldehyde idlula kakhulu izinga futhi ihlangabezana nezidingo zokudla kwezempilo. 8 izikhathi. Ukulimala okuqondile okubangelwa ukusetshenziswa isikhathi eside kwesitsha esinjalo ukuthi kungabangela i-leukemia. Izinga lokushisa lokusetshenziswa kwe-melamine alikwazi ukusuka ku--20°C kuya ku-120°C, kodwa izindawo zokudlela eziningi nemizi izoba namafutha e-chili ashisayo ezitsheni ze-melamine. Izinga lokushisa likawoyela we-chili elishisayo livame ukuba ngu-150°C. Ngaphezu kwalokho, ngenxa yezakhiwo zokubola zamafutha, Ngakho-ke kukhishwa i-formaldehyde eningi.
Uma kukhona "isitsha esisongela ukuphila", kufanele futhi kube "indebe esongela ukuphila". Izinkomishi zamanzi ezenziwe nge-melamine zithengiswa ezimakethe ezihlukahlukene emhlabeni jikelele. Abantu bavame ukungazinaki izingozi zokuphepha. Abathengisi bazophinde bakhuthaze ukusetshenziswa kwe-melamine ngoba indawo yokubilisa yamanzi ingu-100°C. Izinkomishi zamanzi ezenziwe nge-amine azinangozi emzimbeni womuntu, kodwa akekho usomabhizinisi ozosho ukuthi kuneziphuzo ezine-acidic. Kungakhathaliseki ukuthi i-carbonic acid noma i-acetic acid, izophoqa ukudluliselwa kwe-formaldehyde. Abangane abaningi banesipiliyoni sokusebenzisa izinkomishi zamanzi ezenziwe nge-melamine eziphuzweni ze-carbonate
Ezimpilweni zethu zansuku zonke, iningi labangane bethu linolwazi olubuthakathaka mayelana nokuhlonza ukuphepha kwezinkomishi zamanzi. Namuhla ngizokunikeza iziphakamiso. Uma ungafuni ngempela ukwahlulela ukuthi inkomishi yamanzi iphephile futhi inempilo yini, into yokuqala inkomishi yamanzi engilazi. Njengamanje, inkomishi yamanzi engilazi zonke izinkomishi zamanzi. Into ebaluleke kakhulu ukukhomba ukuthi ingilazi iqhunyiswa emazingeni okushisa aphezulu, futhi zonke izinto eziyingozi zisuswa ngokudubula. Ngesikhathi esifanayo, ngaphezu kokuba buthakathaka, ibhodlela lamanzi engilazi libuye lizinzile kakhulu kuzo zonke izinto futhi ayesabi i-asidi.
Okwesibili, wonke umuntu usebenzisa izinkomishi zamanzi ezenziwe ngensimbi engagqwali engu-304 noma insimbi engagqwali engu-316. Ngeke ngingene emininingwaneni mayelana nendlela yokuhlonza i-304 ne-316. Sicela ufunde izihloko ezedlule kuwebhusayithi. Kodwa-ke, uma usebenzisa izinkomishi zamanzi zensimbi engagqwali, zama ukugwema ukuqukatha iziphuzo ezine-asidi nemikhiqizo yobisi.
