I-Melamine Cyanurate (MCA) engenawo amalangabi angenawo i-halogen
Isingeniso
I-Melamine Cyanurate (MCA) iyi-halogen-free flame retardant esebenza kahle kakhulu equkethe i-nitrogen. Isetshenziswa kabanzi embonini yepulasitiki njenge-flame retardant.
Ngemva kokumuncwa kokushisa kwe-sublimation kanye nokubola kwezinga lokushisa eliphezulu, i-MCA iyabola ibe yi-nitrogen, amanzi, i-carbon dioxide kanye namanye amagesi asusa ukushisa kwe-reactant ukuze kufezwe injongo ye-flame retardant. Ngenxa yokushisa okuphezulu kwe-sublimation decomposition kanye nokuqina okuhle kokushisa, i-MCA ingasetshenziswa ekucubungulweni kwe-resin okuningi.

Izici
I-MCA iyi-langabi elibambayo elisebenza kahle kakhulu ngenxa yokuqukethwe kwayo okuphezulu kwe-nitrogen, okwenza ibe ukukhetha okuhle kakhulu kwezinto ezidinga ukusha okuncane. Ukuqina kwayo kokushisa, kuhlanganiswe nobuthi bayo obuphansi, kuyenza ibe yindlela ethandwayo kwezinye izinto ezivimbela umlilo ezisetshenziswa kakhulu njengezinhlanganisela ze-brominated. Ngaphezu kwalokho, i-MCA ayibizi kakhulu futhi kulula ukuyikhiqiza, okwenza kube ukukhetha okungabizi kakhulu kwezicelo ezinkulu.
Isicelo
I-MCA isetshenziswa njengento evimbela ilangabi ezintweni eziningi ezahlukene, okuhlanganisa ama-polyamides, ama-polyurethane, ama-polyester, nama-epoxy resins. Iwusizo kakhulu kumapulasitiki obunjiniyela, adinga ukusebenza kahle kwezinga lokushisa eliphezulu kanye nokusha okuphansi. I-MCA ingasetshenziswa nasezindwangu, opendeni, kanye nezingubo zokugqoka ukuze kuthuthukiswe ukumelana nomlilo. Embonini yokwakha, i-MCA ingangezwa ezintweni zokwakha ezifana nokushisa kwe-foam ukuze kuncishiswe ukusabalala komlilo.
Ngaphezu kokusetshenziswa kwayo njengesivimbeli somlilo, i-MCA inezinye izinhlelo zokusebenza. Ingasetshenziswa njenge-ejenti yokwelapha ama-epoxies, futhi iboniswe ukuthi iyasebenza ekunciphiseni inani lentuthu ekhishwa ngesikhathi somlilo, okwenza ibe yingxenye ebalulekile ezintweni ezivimbela umlilo.
