Ubushinwa buremereye cyane alumina yumuriro wamatafari uruganda nabakora | Rongsheng

Ibisobanuro bigufi:

Amatafari maremare ya alumina ni ubwoko bwo kwanga, igice nyamukuru cyacyo ni Al2O3. Niba ibirimo Al2O3 birenze 90%, byitwa amatafari ya corundum. Bitewe nubutunzi butandukanye, ibipimo byibihugu bitandukanye ntabwo bihuye rwose. Kurugero, mubihugu byu Burayi, imipaka yo hasi yibirimo bya Al2O3 kubikoresho byo hejuru bya alumina ni 42%. Mubushinwa, ibiri muri Al2O3 mumatafari maremare ya alumina muri rusange bigabanijwemo ibyiciro bitatu: Icyiciro cya I - Ibirimo Al2O3> 75%; icyiciro cya II - Ibirimo Al2O3 ni 60-75%; icyiciro cya III - Ibirimo Al2O3 ni 48-60%.

Gusaba:

Amatafari maremare ya alumina akoreshwa cyane mububiko bw'itanura ryinganda imbere, nk'itanura riturika, itanura rishyushye, itanura ry'amashanyarazi hejuru, reverberator, itanura rya sima n'ibindi. Uretse ibyo, amatafari maremare ya alumina nayo akoreshwa cyane nk'amatafari yo kugenzura, guhagarika sisitemu yo gukomeza guterana, amatafari ya nozzle, n'ibindi.
