Amatafari ya Corundum
Itafari rya Corundumni igicuruzwa kidakora neza cyane gifite korundum nk'igice cy'ingenzi cya kristale, gikoreshwa cyane mu nganda zikoresha ubushyuhe bwinshi. Gikunzwe n'inganda zitandukanye kubera ko kidakora neza cyane mu bushyuhe bwinshi, imbaraga za mekanike n'ubudahinduka bwa shimi. Hasi aha hari intangiriro irambuye ku matafari yacu ya korundum, harimo gushyira mu byiciro ibicuruzwa, imiterere y'imikorere, imiterere ya shimi, imirima ikoreshwamo n'inyungu z'ibicuruzwa.
Gushyira mu byiciro ibicuruzwa
Dukurikije imiterere y’ibinyabutabire (ibice by’inyongera) cyangwa amasoko y’ibikoresho fatizo, amatafari ya corundum agabanyijemo ibice bine, buri kimwe gifite imiterere yihariye n’uburyo bwo kuyakoresha mu rwego rwo guhaza ibyifuzo bitandukanye by’inganda.
1. Itafari rya Corundum ryera
Amagambo y'ingenzi:Ubuziranenge bwinshi, umwanda muke, ubushyuhe bwinshi
Ibiranga imbaraga:Yakozwe muri alumina y’inganda, ifite umwanda muke cyane (cyane cyane icyuma gikozwe muri okiside nke), bityo ikaba ifite umweru. Ifite ubushobozi bwo kugabanya ubushyuhe bwinshi n’imbaraga za mekanike, ifite ubuziranenge bwiza mu matafari ya corundum.
Ibikubiye muri Al₂O₃:≥ 99%
2. Itafari rya Korundum y'umukara
Amagambo y'ingenzi:Ihendutse, Ifite Intego Rusange, Irwanya Gutakaza Ibiciro
Ibiranga:Ishongeshejwe na bauxite mu itanura ry'amashanyarazi, irimo ingano nto ya oxide y'icyuma (igaragaza umukara). Irangwa n'imiterere y'ubucucike, irwanya cyane amatafari, kandi ikagira igiciro cyiza ugereranyije n'amatafari yera ya corundum.
Ibikubiye muri Al₂O₃:≥ 95%
3. Itafari rya Chrome Corundum
Amagambo y'ingenzi:Ubudahangarwa n'Ingese, Itanura ry'Ikirahure, Itanura rya Sima
Ibiranga:Chromite cyangwa chromium oxyde byongerwa muri corundum. Ikiranga cyane ni ubudahangarwa bukomeye cyane ku kirahure gishonga cyangwa gishonga, ndetse no kudahangarwa neza n'ubushyuhe icyarimwe.
Ibikubiye muri Al₂O₃:90-95%
4. Itafari rya Zirconia Corundum
Amagambo y'ingenzi:Ubudahangarwa bw'imyenda, Ubudahangarwa bw'ubushyuhe, Urukuta rw'ifuru y'ikirahure
Ibiranga:Kongerwamo Zircon. Kongeramo ibice bya zircon byongera cyane ubushobozi bwo kudashira kw'ibikoresho no kudahungabana kw'ubushyuhe (kwirinda gukonja no gushyuha vuba).
Ibikubiye muri Al₂O₃:60-80% (+ ZrO₂)
Ibiranga Imikorere:
Nk'ibikoresho birwanya ubushyuhe bwinshi, amatafari ya corundum afite imiterere myiza cyane, kandi ubwoko butandukanye bw'amatafari ya corundum burushaho kunoza imikorere yihariye hashingiwe ku miterere yavuzwe haruguru:
1. Ubushyuhe bwinshi:Ubushyuhe bushobora kugera hejuru ya 1750℃, kandi bimwe mu bikoresho bifite isuku nyinshi (nk'amatafari yera ya corundum) bishobora kwihanganira ubushyuhe bwinshi igihe kirekire burenga 1800℃, bigakomeza kugumana ubushyuhe bwiza mu bidukikije bitagira ubwihindurize cyangwa kwangirika.
2. Ingufu nyinshi:Ifite imbaraga zo gukandagira mu bushyuhe bwinshi, kugeza kuri 340MPa, kandi ishobora kwihanganira imitwaro ya mekanike mu bushyuhe bwinshi. Muri yo, amatafari yera ya corundum afite imbaraga zidasanzwe za mekanike mu bushyuhe bwinshi.
3. Gukomera neza mu binyabutabire:Irwanya cyane aside cyangwa alkaline, ibyuma, ikirahure gishonga, nibindi, kandi ntibyoroshye kubyangiza. Amatafari yera ya corundum afite ubushobozi bwo kudahinduka bitewe n'uko asukuye cyane.
4. Ubudahangarwa bwiza bwo kurwanya isuri no kurwanya isuri:Cyane cyane ifite ubudahangarwa bukomeye ku bintu bivanze n’aside, bidafite aho bibogamiye ndetse n’ibindi bintu bishongeshejwe na alkaline. Itafari rya Chrome corundum ni ryiza cyane muri ubu buryo, rishobora kongera igihe cyo kurikoresha.
5. Guhagarara neza mu gihe cy'ubushyuhe:Nubwo atari meza nk'ibikoresho bimwe na bimwe birimo silikoni cyangwa magnesia, bishobora kunozwa cyane wongeyeho zircon (nk'amatafari ya zirconia corundum) cyangwa ugahindura imiterere y'uduce. Amatafari ya zirconia corundum afite ubushobozi bwo guhagarara neza mu bushyuhe.
Amatafari ya Corundum-mulliteni ikintu cy’ingenzi gifite ishusho nziza yo kugabanya ubushyuhe hamwe na corundum na mullite nk'ibice by'ingenzi bya kristale. Bitewe n'ingaruka z'ibikorwa by'ibice bibiri by'ingenzi, gihuza ubushyuhe bwinshi n'ubudahangarwa bwa corundum hamwe n'ubushyuhe bwiza bwo kudahungabana kwa mullite. Iki gicuruzwa kizwi cyane mu nganda zishyuha cyane ku isi nka metallurgy, ikirahure, peteroli, n'umukara wa karuboni, gitanga ibisubizo byizewe ku bikoresho by'ingenzi byo mu itanura kandi kirushaho kunoza imikorere y'ibikoresho n'igihe cyo kubikoresha.
Ibyiza by'ingenzi mu mikorere:
1. Ubudahangarwa budasanzwe bw'ubushyuhe:Iyi ni yo nyungu yayo y'ingenzi. Mullite ifite ubushobozi buke bwo kwaguka k'ubushyuhe, kandi imiterere yayo imeze nk'ikirahure igabanya umuvuduko uterwa n'ihindagurika ry'ubushyuhe, bigabanya cyane gucika kw'ubukonje n'ubushyuhe ku bushyuhe bwinshi. Imikorere yayo iruta iyamatafari ya corundum.
2. Ingufu ziringaniye no kurwanya ingese:Kuba hariho igice cya corundum bitanga imbaraga nyinshi haba mu bushyuhe bwo mu cyumba no mu bushyuhe bwinshi, ariko kandi binatanga ubudahangarwa bwiza ku bintu bivanze n’aside, ibirahure bishongeshejwe, n’ibindi bikoresho. Nubwo ubudahangarwa bwayo bwa alkali buri hasi gato ugereranyije n’amatafari ya chrome corundum, itanga uburyo bwinshi bwo kuyikoresha.
3. Ubushyuhe buringaniye:Ugereranyije n'amatafari ya corundum afite ubucucike bwinshi, itanga ubushobozi bwo gutwara ubushyuhe buke mu gihe igumana urwego runaka rwo gukingira ubushyuhe, ikagabanya ubushyuhe butakaza mu bikoresho bikoresha ubushyuhe bwinshi kandi bigatuma ikoreshwa mu gukenera gukingira ubushyuhe.
