TF-MCA Halogen-free Flame Retardant Melamine Cyanurate (MCA)
Hoʻolauna
ʻO Melamine Cyanurate (MCA) kahi mea pale ahi kaiapuni ʻole halogen kiʻekiʻe e loaʻa ana ka naikokene. Hoʻohana nui ʻia ia i ka ʻoihana plastik ma ke ʻano he mea pale ahi.
Ma hope o ka omo ʻana o ka wela sublimation a me ka decomposition wela kiʻekiʻe, ua decomposed ʻo MCA i ka nitrogen, ka wai, ke kalapona dioxide a me nā kinoea ʻē aʻe e lawe aku i ka wela reactant e hoʻokō ai i ke kumu o ka flame retardant. Ma muli o ke kiʻekiʻe o ka mahana decomposition sublimation a me ka paʻa wela maikaʻi, hiki ke hoʻohana ʻia ʻo MCA no ka hapa nui o ka hana resin.

Nā ʻano
He mea pale ahi maikaʻi loa ʻo MCA ma muli o kona nui o ka naikokene, e lilo ia i koho maikaʻi loa no nā mea e pono ai ka lapalapa haʻahaʻa. ʻO kona kūpaʻa wela, i hui pū ʻia me kona ʻawahia haʻahaʻa, e lilo ia i mea koho kaulana i nā mea pale ahi ʻē aʻe i hoʻohana pinepine ʻia e like me nā hui brominated. Eia kekahi, he ʻano kūʻai ʻole ʻo MCA a maʻalahi hoʻi e hana, e lilo ia i koho waiwai no nā noi nui.

Hoʻohana ʻia ʻo MCA ma ke ʻano he mea pale lapalapa i nā ʻano mea like ʻole, me nā polyamides, polyurethanes, polyesters, a me nā resins epoxy. He mea pono loa ia i nā plastics ʻenekinia, kahi e pono ai ka hana wela kiʻekiʻe a me ka flammability haʻahaʻa. Hiki ke hoʻohana ʻia ʻo MCA i nā lole, nā pena, a me nā uhi e hoʻomaikaʻi i ke kūpaʻa lapalapa. I ka ʻoihana kūkulu hale, hiki ke hoʻohui ʻia ʻo MCA i nā mea kūkulu hale e like me ka insulation foam e hōʻemi i ka laha ʻana o ke ahi.
Ma waho aʻe o kona hoʻohana ʻia ʻana ma ke ʻano he mea pale ahi, loaʻa iā MCA nā hana ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻōla no nā epoxies, a ua hōʻike ʻia he pono ia i ka hōʻemi ʻana i ka nui o ka uahi i hoʻokuʻu ʻia i ka wā o ke ahi, e lilo ia i mea waiwai nui i nā mea pale ahi.
