Amatafari ya alumina menshi yo gukoresha mu itanura

Amatafari ya alumina menshi yo gukoresha mu matanura acukurwaho umuriro akozwe muri bauxite yo mu rwego rwo hejuru nk'ibikoresho by'ingenzi, bigashyirwa mu matsinda, bigakanda, bikanikwa kandi bigacanwa ku bushyuhe bwinshi. Ni ibikoresho birwanya ubushyuhe bikoreshwa mu matanura acukurwaho umuriro.

1. Ibipimo ngenderwaho n'ibinyabutabire byerekana amatafari menshi ya alumina

2. Amatafari maremare ya alumina akoreshwa mu itanura riturika ari hehe?

Amatafari ya aluminiyumu yubakishijwe ku mwobo w'itanura riturika. Umugozi w'itanura uherereye mu gice cyo hejuru cy'itanura riturika. Ubugari bwaryo bugenda bwiyongera kuva hejuru kugera hasi kugira ngo buhuze n'ubushyuhe bw'umuriro kandi bugabanye ubushyuhe bw'urukuta rw'itanura ku mwobo. Umubiri w'itanura ufata itanura riturika. 50%-60% by'uburebure bufatika. Muri iki gihe, imiterere y'itanura igomba kuzuza ibyo bisabwa, kandi ibiranga amatafari ya aluminiyumu mato ni ukudakomera cyane, ubushyuhe bwinshi bworoshye iyo umutwaro uremereye, kurwanya aside, kurwanya alkali, kurwanya cyane isuri, no kudashira neza. Irashobora kunyurwa, bityo birakwiriye cyane ko umubiri w'itanura riturika ushyirwamo amatafari ya aluminiyumu mato.

Ibi byavuzwe haruguru ni intangiriro y'amatafari maremare ya alumina yo gukoresha mu matanura. Imiterere y'itanura rikoresha alumina iragoye kandi hari ubwoko bwinshi bw'ibikoresho birwanya ubushyuhe. Amatafari maremare ya alumina ni kimwe muri byo. Hari uburyo butatu cyangwa butanu bwo gukoresha amatafari maremare ya alumina. Amatafari maremare ya Robert ashobora gukoreshwa mu matanura atandukanye. Niba bibaye ngombwa, twandikire.
