Ibisobanuro by'amatafari ya alumina
Amatafari yo gutwika ya alumina ni ubwoko bushya bw'ibikoresho byo gushyushya bishyushya mu bushyuhe bwinshi kandi bikozwe muri alumina yo mu nganda mu itanura ry'amashanyarazi binyuze mu gushonga no guhumeka. Amatafari yo gutwika ya alumina ni kristale ya a-Al2O3 kandi igice kinini ni alumina ishobora gukorwamo ubwoko bwose bw'ibicuruzwa bifite imiterere itandukanye kugira ngo bikoreshwe mu bushyuhe bwo hejuru bwa 1800℃ hamwe n'imbaraga nyinshi za mekanike n'ubucucike buke.
Imiterere y'amatafari ya alumina
- Uburemere bworoheje,
- Kuzigama ingufu,
- Igiciro gito cy'ubwubatsi,
- Ubudahangarwa bw'ubushyuhe bwinshi,
- Guhindura umurongo muke wo gushyushya,
- Ubudahangarwa bwiza bw'ubushyuhe.
Uburyo bwo gukora amatafari ya alumina
Ibumba rya aluminiyumu rikoresha umupira w’urubura rwa aluminiyumu nk’ibikoresho by’ingenzi, ifu nziza cyane nk’iy’inyongera, n’ibintu bikomoka ku bimera nk’iy’ubuhumekero binyuze mu gushushanya no kumisha, hanyuma bigashyirwa mu itanura rishyuha cyane.
Akamaro k'amatafari y'ibirayi bya Alumina
Amatafari yo mu bwoko bwa aluminiyumu bubblle afite imiterere yo gukingira ubushyuhe n'ubushobozi buke bwo gutwara ubushyuhe, ibyo bikaba bishobora gutuma ubushyuhe burushaho kwiyongera, bikagabanya ubushyuhe buseswa kandi bikongera imikorere myiza y'ubushyuhe. Gukoresha amatafari yo mu bwoko bwa aluminiyumu bubblle bishobora kuzigama ingufu kugeza kuri 30%. Kandi ubushyuhe bwo gukoresha aluminiyumu bubblle bugera kuri 1750 ℃. Ubushyuhe buhagaze neza kandi umuvuduko wo kongera gushyushya ni muto, aluminiyumu bubblle ishobora gutuma ubuzima buramba.

Gukoresha Alumina Bubble Brick
Amatafari y'ifumbire ya Alumina ni ubwoko bw'ibikoresho by'ingenzi cyane birwanya ubushyuhe bwinshi n'ibikenewe byihariye mu itanura n'itanura, bikoreshwa cyane nk'amatafari akingira ubushyuhe mu gukingira urwego rw'itanura n'itanura, kandi amatafari y'ifumbire ya aluminiyumu ashobora gukoreshwa mu gukora quartz nziza cyane mu nganda z'ibikoresho by'ikoranabuhanga nk'amatafari ya keramike muri turbine za gaze n'amatafari yo gukingira mu byuma bitanga umwuka.
Uruganda rukora amatafari ya alumina Bubble rukomoka mu ruganda rwa RS Refractory
Uruganda rukora amatafari ya alumina mu Bushinwa nk'umwuga mu gukora amatafari ya alumina mu Bushinwa, rufite inyungu nyinshi ku isoko. Niba ukeneye amatafari ya aluminiyumu, cyangwa ufite ibibazo ku matafari ya aluminiyumu ku bijyanye n'ibipimo fatizo n'imiti, twandikire ku buntu, tuzaguha amatafari ya aluminiyumu meza cyane.
