Kev faib tawm thiab cov yam ntxwv ntawm mica ntawv

Classification thiab yam ntxwv ntawm mica ntawv

Tam sim no, muaj peb hom mica ntawv nyob rau hauv kev ua lag luam: daim ntawv muscovite, ntuj phlogopite ntawv, thiab hluavtaws fluorophlogopite ntawv.

Peb hom mica ntawv muaj me me ntawm cov khoom decomposition hauv qab 500 ℃, thiab qhov hnyav poob qis dua 1%; Thaum cov ntawv muscovite yog rhuab mus rau 550 ℃ lossis ntau dua, cov ntawv phlogopite mica ntuj muaj ntau cov dej hauv cov qauv thaum rhuab mus rau 850 ℃ lossis ntau dua. Thaum cov ntaub ntawv hluavtaws fluorophlogopite mica decomposed thiab rhuab mus rau saum 1050 ° C, ntau cov fluoride ions kuj raug tso tawm. Tom qab ib tug loj tus naj npawb ntawm cov khoom yog decomposed, lawv nplaim retardancy thiab siab tsis kam poob sharply. Yog li ntawd, qhov siab tshaj plaws siv kub ntawm daim ntawv muscovite yog 550 ° C, qhov siab tshaj plaws siv kub ntawm cov ntawv phlogopite yog 850 ° C, thiab Taicheng fluorphlogopite Qhov siab tshaj plaws ua haujlwm kub ntawm ntawv yog 1 050 ° C.
