TF-MCA Halogen-isina Murazvo Unodzivirira Melamine Cyanurate (MCA)
Nhanganyaya
Melamine Cyanurate (MCA) chinhu chinodzivirira moto chezvakatipoteredza chisina halogen chinoshanda zvakanaka uye chine nitrogen. Chinoshandiswa zvakanyanya muindasitiri yepurasitiki sechinhu chinodzivirira moto.
Mushure mekunyudzwa kwekupisa kwe sublimation uye kuora kwekupisa kwakanyanya, MCA inoora kuita nitrogen, mvura, kabhoni dhayokisaidhi uye mamwe magasi anobvisa kupisa kwe reactant kuti zvizadzise chinangwa chemurazvo unodzivisa moto. Nekuda kwekupisa kwakanyanya kwe sublimation uye kugadzikana kwakanaka kwekupisa, MCA inogona kushandiswa pakugadzira resin yakawanda.

Hunhu
MCA inodzivirira moto inoshanda zvikuru nekuda kwehuwandu hwayo hwakawanda hwenitrogen, zvichiita kuti ive sarudzo yakanaka yezvinhu zvisingade kupisa zvakanyanya. Kugadzikana kwayo pakupisa, pamwe chete nehupfu hushoma, zvinoita kuti ive imwe nzira inozivikanwa kune dzimwe dzinodzivirira moto dzinoshandiswa zvakanyanya senge brominated compounds. Pamusoro pezvo, MCA haina kudhura zvakanyanya uye iri nyore kugadzira, zvichiita kuti ive sarudzo inodhura zvishoma pakushandisa kukuru.
Kushandiswa
MCA inoshandiswa sechinhu chinodzivirira moto muzvinhu zvakasiyana-siyana, zvinosanganisira mapolyamides, mapolyurethane, mapolyester, uye epoxy resins. Inonyanya kubatsira mumapurasitiki ekugadzira, ayo anoda kushanda zvakanaka uye asingatsvedzi zvakanyanya. MCA inogona kushandiswawo mumachira, pendi, uye machira ekuwedzera kudzivirira moto. Muindasitiri yekuvaka, MCA inogona kuwedzerwa kune zvinhu zvekuvaka zvakaita sekudzivirira furo kuderedza kupararira kwemoto.
Pamusoro pekushandiswa kwayo semushonga unodzivirira moto, MCA ine zvimwe zvinoshandiswawo. Inogona kushandiswa semushonga unoporesa ma epoxies, uye yakaratidzwa kuti inoshanda mukuderedza huwandu hweutsi hunoburitswa panguva yemoto, zvichiita kuti ive chinhu chinokosha muzvinhu zvinodzivisa moto.
