Alumina ya Brown Fuse, 95% vs 90%

Mawu Ofunika: abrasive, alumina, Refractory, ceramic

Alumina yofiirira yosakanikirana ndi mtundu wa zinthu zopangidwa ndi zinthu zomangira zomwe zimapangidwa posakaniza bauxite ndi zinthu zina mu uvuni wamagetsi. Ili ndi kuuma kwakukulu komanso kulimba, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana.

Ntchito zazikulu za alumina yofiirira yosakanikirana ndi izi:

• Monga chinthu chopukutira mchenga, kupukutira, ndi kudula.

• Monga chinthu chotetezera kutentha kwa uvuni ndi zida zina zotenthetsera kwambiri.

• Monga chida chopangira zinthu zooneka ngati zadothi kapena zosaoneka ngati zadothi.

• Monga chophimba chopangira zitsulo, ma laminate, ndi zojambula.

Pali zinthu zosiyanasiyana za BFA, monga 95%, 90%, 85%, 80% komanso ngakhale zochepa.

Chiwerengero chikakhala chachikulu, kuyera ndi kuuma kwa chinthucho kumakhala kwakukulu. Izi zitha kukhudza mtundu, kukula, ndi kagwiritsidwe ntchito ka chinthucho.

Alumina yofiirira yosakanikirana 95% ili ndi mtundu woyera kapena wosawoneka bwino, pomwe alumina yofiirira yosakanikirana 90% ili ndi mtundu wa bulauni kapena wachikasu. Izi zimachitika chifukwa cha zinthu zosafunika zomwe zili mu zinthuzo, monga titanium oxide ndi iron oxide.

Alumina yosakanikirana ya bulauni 95% imagwiritsidwa ntchito makamaka m'mawilo opukutira ndi zida zodulira, pomwe alumina yosakanikirana ya bulauni 90% imagwiritsidwa ntchito m'mawilo opukutira, sandpaper, ndi zinthu zina zokwawa. Kuyera kwake kukakhala kwakukulu, kukana kwa kukwawa kwa zinthuzo kumakhala kwakukulu.

Alumina yosakanikirana ya bulauni 95% ili ndi kapangidwe ka kristalo ka hexagonal, pomwe alumina yosakanikirana ya bulauni 90% ili ndi kapangidwe ka kristalo ka trigonal. Mapangidwe osiyanasiyana a kristalo angakhudze kukula ndi mawonekedwe a tinthu tating'onoting'ono.
