Isingeniso
I-Melamine (ifomula yamakhemikhali i-C3H6N6) iyinhlanganisela yezinto eziphilayo enezinto ezihlukahlukene kanye nokusetshenziswa.
Ikhwalithi:
1. Izakhiwo zomzimba: I-Melamine iyikristale engenambala eqinile enamaphoyinti ancibilikayo nabilayo.
2. Izici zamakhemikhali: I-Melamine iyinhlanganisela ezinzile akulula ukubola ekamelweni lokushisa. Iyancibilika emanzini nakwezinye izincibilikisi eziphilayo njenge-methanol ne-acetic acid.
Sebenzisa:
1. Embonini, i-melamine ivame ukusetshenziswa njengento eluhlaza yama-resin okwenziwa, njenge-acrylic fibre, amapulasitiki e-phenolic, njll. Inokushisa okuhle kakhulu nokumelana namakhemikhali.
2. I-Melamine ingasetshenziswa futhi njengesinqamuleli somlilo, odayi, izingulube nezithasiselo zephepha.
Indlela:
Ukulungiswa kwe-melamine kuvame ukwenziwa ukusabela kwe-urea ne-formaldehyde. I-Urea ne-formaldehyde isabela ngaphansi kwezimo ze-alkaline ukukhiqiza i-melamine namanzi.
Ulwazi Lokuphepha:
1. I-Melamine inobuthi obuphansi futhi inomthelela omncane kubantu nasendaweni ezungezile.
3. Lapho usebenzisa futhi ugcina i-melamine, gwema ukuthinta isikhumba namehlo, futhi gqoka amagilavu okuzivikela kanye nezibuko uma kudingeka.
4. Ekulahlweni kukadoti, imithetho efanele kanye neziqondiso kufanele kuthotshelwe ukugwema ukungcoliswa kwemvelo.
