Umuyoboro wa alumina udapfa kwambarwa ushyira imbaraga nshya mu nganda zitwara umwuka

Mu nganda, amashanyarazi akoreshwa mu byuma bikoresha umwuka akoreshwa cyane mu nganda zikoresha ingufu, imiti n'izindi, ariko kwangirika kw'imiyoboro y'amazi byagiye biba ikibazo mu nganda, byongera ikiguzi kandi bigira ingaruka ku musaruro. Kugaragara kw'imiyoboro ya alumina idashira byakemuye iki kibazo kandi biba amahitamo mashya ku nganda.

Imiyoboro ya alumina idashira irambitse irimo ibumba rya alumina rifite ubuziranenge buhanitse, rifite ubukana hafi ya 90HRA, kandi ubukana bw'ubudashira buruta inshuro nyinshi imiyoboro isanzwe y'icyuma. Iyo umwuka wihuta cyane utuma ibikoresho bikwirakwira ku rukuta rw'imbere rw'umuyoboro, bishobora kurwanya ubusaza no kongera igihe cyo kuwukoresha. Urugero, mu kigo cy'imiti, imiyoboro isanzwe y'icyuma irashira cyane mu mezi make iyo itwara ibikoresho birimo uduce duto, kandi igomba gusimburwa kenshi; nyuma yo gusimbuza imiyoboro ya alumina idashira, ubusaza buba buke nyuma y'imyaka myinshi ikora.

Ifite kandi ubushobozi bwo kwihanganira ubushyuhe bwinshi. Igitambaro cya ceramic gishobora kwihanganira ubushyuhe bwinshi buri hejuru ya dogere 1200℃, kandi kwihanganira ubushyuhe biri hejuru mu buryo bwihariye. Ishobora gukora neza mu gutwara ibintu mu bushyuhe bwinshi kugira ngo irinde umutekano w'uburyo bwo gutwara ibintu mu mwuka. Byongeye kandi, ifite ubushobozi bukomeye bwo kudahinduka mu binyabutabire. Iyo itwara ibintu byangiza mu nganda z'ibinyabutabire, ishobora kurwanya kwangirika kw'ibinyabutabire nka aside, alkali, n'umunyu kugira ngo ifashe ibicuruzwa byangiza.

Byongeye kandi, umuyoboro wa alumina udashira ni woroshye mu buremere, ushobora kugabanya umutwaro kuri sisitemu y'imiyoboro, woroshye gushyiraho no kubungabunga, kandi ugabanya ikoreshwa ry'ingufu. Hariho uburyo butandukanye bwo gushyiraho, kandi uburyo bwo guhuza bushobora gutoranywa hakurikijwe ibikenewe kugira ngo buhuze n'ibidukikije bigoye by'ubuhanga.

Bitewe n’iterambere ry’ikoranabuhanga mu nganda, hashyizweho ibisabwa byinshi ku buryo bwo gutwara ibintu hakoreshejwe umwuka. Bitewe n’imikorere myiza, umuyoboro wa alumina udashira ufite amahirwe menshi yo gukoreshwa. Urashobora gukemura ibibazo byo kwangirika, kunoza imikorere myiza y’umusaruro, kugabanya ikiguzi, guteza imbere iterambere ry’ikoranabuhanga ryo gutwara ibintu hakoreshejwe umwuka, no gufasha inganda zitandukanye gutera imbere mu buryo bwiza. Uzagira uruhare runini mu bindi bihe bizaza.
