Melamine Cyanurate (MCA) idafite Halogen irinda umuriro (TF-MCA)
Intangiriro
Melamine Cyanurate (MCA) ni umuti urinda umuriro mu bidukikije udafite halogen kandi urimo azote. Ukoreshwa cyane mu nganda za pulasitiki nk'umuti urinda umuriro.
Nyuma yo gukoresha ubushyuhe bwa sublimation no kubora cyane, MCA irahinduka azote, amazi, dioxyde de carbone n'indi myuka ikuraho ubushyuhe bwa reactant kugira ngo igere ku ntego yo kugabanya ubushyuhe. Kubera ubushyuhe bwinshi bwo kubora sublimation no kudahinduka neza n'ubushyuhe, MCA ishobora gukoreshwa mu gutunganya resin nyinshi.

Ibiranga
MCA ni umuti ugabanya umuriro cyane bitewe n’uko ifite azote nyinshi, bigatuma iba amahitamo meza ku bikoresho bidakenera umuriro mwinshi. Kuba ubushyuhe bwayo burambye, hamwe n’uburozi buke, bituma iba uburyo buzwi bwo gusimbura ibindi bintu bigabanya umuriro bikunze gukoreshwa nk’ibinyabutabire bya bromine. Byongeye kandi, MCA irahendutse kandi yoroshye kuyikora, bigatuma iba amahitamo ahendutse ku bikorwa binini.
Porogaramu
MCA ikoreshwa nk'ikintu kidakoresha umuriro mu bikoresho bitandukanye, harimo polyamides, polyurethane, polyester, na epoxy resins. Ifite akamaro cyane cyane muri pulasitiki z'ubuhanga, zisaba imikorere myiza kandi zidashya cyane. MCA ishobora kandi gukoreshwa mu myenda, amarangi, n'amabara kugira ngo yongere ubushobozi bwo kurwanya umuriro. Mu nganda z'ubwubatsi, MCA ishobora kongerwa ku bikoresho by'ubwubatsi nko gukingira ifuro kugira ngo igabanye ikwirakwira ry'umuriro.
Uretse gukoreshwa kwayo nk'umuti ugabanya umuriro, MCA ifite n'izindi gahunda. Ishobora gukoreshwa nk'umuti uvura epoxies, kandi byagaragaye ko igira akamaro mu kugabanya ingano y'umwotsi usohoka mu gihe cy'inkongi, bigatuma iba ingenzi mu bikoresho bigabanya umuriro.
