TF-MCA Halogen-Free Flame Retardant Melamine Cyanurate (MCA)
Mawu Oyamba
Melamine Cyanurate (MCA) ndi chida champhamvu kwambiri cha halogen chosagwiritsa ntchito malawi okhala ndi nayitrogeni.Amagwiritsidwa ntchito kwambiri m'makampani apulasitiki ngati choletsa moto.
Pambuyo sublimation kutentha mayamwidwe ndi mkulu kutentha kuwonongeka, MCA ndi decomposed kuti asafe, madzi, carbon dioxide ndi mpweya wina amene amachotsa reactant kutentha kukwaniritsa cholinga lawi retardant.Chifukwa cha kutentha kwambiri kwa kutentha kwa sublimation ndi kukhazikika kwabwino kwa kutentha, MCA ingagwiritsidwe ntchito pokonza utomoni wambiri.

Makhalidwe
MCA ndiyothandiza kwambiri lawi retardant chifukwa ali mkulu nayitrogeni zili, kupangitsa kukhala yabwino kusankha zipangizo zimene amafuna otsika kuyaka.Kukhazikika kwake kwamatenthedwe, kuphatikiza ndi kawopsedwe kakang'ono, kumapangitsa kuti ikhale njira yodziwika bwino yamafuta ena omwe amagwiritsidwa ntchito kwambiri ngati mankhwala a brominated.Kuphatikiza apo, MCA ndiyotsika mtengo komanso yosavuta kupanga, ndikupangitsa kuti ikhale chisankho chandalama pazogwiritsa ntchito zazikulu.
Kugwiritsa ntchito
MCA imagwiritsidwa ntchito ngati choletsa moto pazinthu zosiyanasiyana, kuphatikiza ma polyamides, polyurethanes, polyesters, ndi epoxy resins.Ndiwothandiza makamaka mu mapulasitiki opangira uinjiniya, omwe amafunikira kutentha kwambiri komanso kutsika pang'ono.MCA itha kugwiritsidwanso ntchito muzovala, utoto, ndi zokutira kuti zithandizire kukana moto.M'makampani omanga, MCA ikhoza kuwonjezeredwa kuzinthu zomangira monga kutsekereza thovu kuti muchepetse kufalikira kwa moto.
Kuphatikiza pakugwiritsa ntchito ngati choletsa moto, MCA ilinso ndi ntchito zina.Ikhoza kugwiritsidwa ntchito ngati mankhwala ochizira ma epoxies, ndipo yasonyezedwa kuti ndi yothandiza kuchepetsa utsi wotuluka pamoto, ndikupangitsa kuti ikhale chigawo chamtengo wapatali muzinthu zowononga moto.
