TF-MCA Halogen-free Flame Retardant Melamine Cyanurate (MCA)
Gabatarwa
Melamine Cyanurate (MCA) babban ingantaccen halogen ne mai hana harshen wuta na muhalli wanda ya ƙunshi nitrogen.Ana amfani da shi sosai a cikin masana'antar robobi azaman mai hana wuta.
Bayan sublimation zafi sha da high zafin jiki bazuwar, MCA ne bazuwar zuwa nitrogen, ruwa, carbon dioxide da sauran iskar gas wanda dauke reactant zafi don cimma manufar harshen retardant.Saboda girman bazuwar zafin jiki da ingantaccen yanayin zafi, ana iya amfani da MCA don yawancin sarrafa guduro.
