Alumina y'umukara ivanze n'amashanyarazi, ikwiriye inganda nshya nyinshi nka nyuko za kirimbuzi, indege, ibicuruzwa bya 3c, ibyuma bitagira umugese, ibumba ryihariye, ibikoresho birwanya kwambara cyane, nibindi.

Ibisobanuro bigufi

Alumina y'umukara ivanze ni kristu y'ibara ry'umukara wijimye ikomoka ku kwivanga kwa bauxite y'icyuma kinini cyangwa bauxite y'icyuma kinini mu itanura ry'amashanyarazi. Ibice byayo by'ingenzi ni α-Al2O3 na hercynite. Ifite ubukana buringaniye, ikomera cyane, yikosora neza, ubushyuhe buke kandi ntishobora gushya cyane, bigatuma iba ibikoresho byiza cyane bidashya.

Uburyo bwo gutunganya: gushonga

Irimo Inganda

Bikwiriye inganda nyinshi nshya nka za kirimbuzi, indege, ibicuruzwa bya 3C, ibyuma bitagira umuze, ibumba ryihariye, ibikoresho bigezweho birwanya kwangirika, nibindi.

Ibiranga Ibicuruzwa

1.Ubuhanga buhanitse
Imbaraga zikomeye zo gukata no kwiyongerera ubushobozi bwo gukata.

2. Igipimo cyiza cy'igiciro / imikorere
Igiciro kiri hasi cyane ugereranyije n'ibindi bikoresho byo mu bwoko bwa abrasive (aggregate) bifite imikorere ingana.

3. Ubwiza bwo hejuru
Ubushyuhe buke buturuka ku buso, bushobora gutwika ibice by'akazi mu gihe cyo gutunganya. Ubukana buringaniye n'irangira ryiza cyane bigerwaho nta ibara ry'ubuso rihinduka cyane.

4. Ibicuruzwa by'icyatsi kibisi
Gukoresha imyanda yose, gushonga kw'ibinure, nta myuka mibi ikomoka mu musaruro.

Porogaramu

Disiki yo Gukata Resin
Kuvanga alumina y'umukara ya 30%-50% na alumina y'umukara yakuwemo bishobora kongera ubukana bwa disiki no kurangiza neza, koroshya ibara ry'ubuso, kugabanya ikiguzi cyo kuyikoresha, no kongera igiciro/imikorere.

Gusukura ibikoresho byo ku meza by'icyuma kitagira umugese
Gusukura ibikoresho byo ku meza by'icyuma kitagira umutuku ukoresheje alumina y'umukara hamwe n'ifu nto bishobora kugira ibara rimwe kandi ntibishobora gutwika ubuso.

Ubuso burwanya ubunyerera budashira
Gukoresha umucanga w’umukara wa alumina nk'ibice bihuriweho kugira ngo habeho umuhanda, ikiraro, aho guparika imodoka bidashira gusa, ahubwo binatanga igipimo cy’igiciro n’imikorere biri hejuru.

Guturika umucanga
Igiti cya alumina cy’umukara gikoreshwa nk'ibikoresho byo guturitsa mu gukuraho ubwandu ku buso, gusukura imiyoboro, gushonga no gutwika umucanga mu gitambaro cya Jean.

Umukandara upfundikiye n'uruziga rwo ku ruhande
Uruvange rwa alumina y'umukara n'umukara rushobora gukorwamo umwenda wo gukurura hanyuma rugahindurwamo umukandara wo gukurura n'uruziga rwo gukurura kugira ngo rukoreshwe mu irangi.

Ipine ya fibre
Igiti cya alumina cyangwa ifu ntoya y'umukara ikoreshwa mu gukora ipine ya fibre yo gusya no gusiga irangi.

Igitambaro cyo gusiga irangi
Ifu y'umukara ya alumina ishobora kandi gukorwamo ubwoko butandukanye bw'isuku yo gusiga neza.
