Isingeniso ekusebenzeni nasekusetshenzisweni kwe izitini ze-aluminium magnesia

Izitini ze-Magnesia alumina zenziwe nge-calcined magnesia (MgO>90%, CaO<2.2%) ezinokuqukethwe kwe-calcium ephansi njengezinto zokusetshenziswa, zengeza cishe u-8% wempushana ye-alumina yezimboni, nokusebenzisa uketshezi lwe-sulfite pulp waste njenge-agent ebophayo. Imikhiqizo eshiswe emazingeni okushisa aphezulu.

Ukwakheka kwesigaba samaminerali sezitini ze-magnesia alumina kusekelwe ku-periclase njengekristalu eyinhloko ne-magnesia alumina spinel (MgO.Al2O3) njenge-matrix. Lesi sakamuva sithatha indawo ye-forsterite esitini se-magnesia futhi iba isibopho se-periclase.

Izitini ze-Magnesia-aluminium zinezakhiwo ezinhle kakhulu ezibalwe ngenhla, ngakho-ke zisetshenziswe kabanzi njengezinto zokwakhiwa kwamatshe ophahleni lweziko ezincibilikisa izinga lokushisa eliphezulu ezifana neziko ezivulekile zensimbi kanye neziko lokuncibilikisa ithusi, futhi bathole impumelelo. umphumela wokwelula impilo yesithando somlilo. Iziko elikhulu elivulekile lingafinyelela kumaziko angama-300, kanti iziko elivulekile eliphakathi nendawo nelincane lineziko ezingaphezu kuka-1000.
