Amatafari maremare ya Alumina Kumuriro

Amatafari-alumina menshi yo gutanura itanura akozwe muri bauxite yo mu rwego rwo hejuru nkibikoresho nyamukuru, bikozwe, bikanda, byumye kandi birasa ku bushyuhe bwinshi. Nibicuruzwa byangiritse bikoreshwa mugutondekanya itanura.

1. Ibipimo bifatika na chimique byamatafari maremare ya alumina

2. Amatafari maremare ya alumina akoreshwa mu itanura riturika?

Amatafari maremare ya aluminiyumu yubatswe ku itanura ry itanura riturika. Igiti cy'itanura giherereye mu gice cyo hejuru cy'itanura riturika. Diameter yacyo igenda yiyongera kuva hejuru kugeza hasi kugirango ihuze nogukwirakwiza ubushyuhe bwumuriro kandi bigabanye guterana kwurukuta rwitanura kumuriro. Umubiri w'itanura ufite itanura riturika. 50% -60% yuburebure bukomeye. Muri ibi bidukikije, itanura rigomba kuba ryujuje ibyo bisabwa, kandi ibiranga amatafari maremare ya alumina ni ukunanirwa cyane, ubushyuhe bworoheje bukabije munsi yumutwaro, kurwanya aside, kurwanya alkali, kurwanya cyane isuri, no kurwanya kwambara neza. Irashobora guhazwa, birakwiriye rero ko itanura ry itanura ritondekanya amatafari maremare ya alumina.

Ibyavuzwe haruguru ni intangiriro yamatafari maremare ya alumina yo gutanura. Ibidukikije biri mu itanura riturika biragoye kandi hari ubwoko bwinshi bwibikoresho byangiritse bikoreshwa. Amatafari maremare ya alumina nimwe murimwe. Hano haribisobanuro 3-5 byamatafari maremare ya alumina yakoreshejwe. Amatafari menshi ya alumina ya Robert arashobora gukoreshwa mumatanura atandukanye. Nibiba ngombwa, twandikire.
