Imipira yo gusya ya Alumina
Ibisobanuro by'igicuruzwa
Imipira yo gusya alumina,zikozwe muri aluminiyumu okiside (Al₂O₃) nk'igice cyazo cy'ingenzi kandi zigakoresha uburyo bwo gusya ibintu mu buryo bwa ceramic, ni imipira y'ceramic ikora neza yagenewe gusya, gusya no gukwirakwiza ibikoresho. Ni imwe mu miyoboro ikoreshwa cyane mu gusya mu nganda (nk'ibumba, gusiga, n'amabuye y'agaciro).
Imipira yo gusya ya alumina ishyirwa mu byiciro bitatu hakurikijwe ingano yayo ya alumina: imipira yo hagati (60%-65%), imipira yo hagati (75%-80%), n'imipira yo hejuru (hejuru ya 90%). Imipira yo hejuru ya aluminiyumu igabanyijemo ibice bibiri: 90-ceramic, 92-ceramic, 95-ceramic, na 99-ceramic, aho 92-ceramic ari yo ikoreshwa cyane bitewe n'imikorere yayo myiza muri rusange. Iyi mipira yo gusya ifite ubukana bwinshi (ubukana bwa Mohs bwa 9), ubucucike bwinshi (hejuru ya 3.6g/cm³), ubukana bwangirika no kwangirika, hamwe no ubushyuhe bwinshi (1600°C), bigatuma ikoreshwa neza mu gusya neza glaze za ceramic, ibikoresho fatizo bya chimique, n'amabuye y'agaciro y'icyuma.
Ibiranga:
Ubukomere bwinshi no kwangirika gukomeye:Ubukana bwa Mohs bugera kuri 9 (hafi ya diyama), hamwe n'igipimo cyo kwangirika gito (<0.03%/1.000 amasaha ku bikoresho bifite isuku nyinshi). Birwanya kwangirika no gucika intege mu gihe cyo gusya igihe kirekire, bigatuma bimara igihe kirekire.
Ubucucike bwinshi n'imikorere myiza yo gusya:Ifite ubucucike bwa 3.6-3.9 g/cm³, itanga imbaraga zikomeye kandi igakata imbaraga mu gihe cyo gusya, ikanoza vuba ibikoresho kugeza ku rwego rwa mikoroni, ifite ubushobozi bwo gukora neza buri hagati ya 20% na 30% ugereranyije n'imipira ya aluminiyumu iri hagati n'iyo hasi.
Umwanda muke n'ubudahangarwa bw'imiti:Imashini zifite ubuziranenge buhanitse zirimo umwanda uri munsi ya 1% (nka Fe₂O₃), zirinda kwanduzwa n'ibintu. Zirwanya aside nyinshi na alkali (usibye aside ikomeye cyane na alkali), ubushyuhe bwinshi (buri hejuru ya 800°C), kandi zikwiriye uburyo butandukanye bwo gusya.
Ingano zoroshye kandi zijyanye n'uburyo ibintu bihagaze:Uwo mupira uboneka mu bunini buri hagati ya mm 0.3 na 20, ushobora gukoreshwa mu bunini bumwe cyangwa buvanze, uhuye n'inganda zitunganya imipira, inganda zitunganya umucanga, n'ibindi bikoresho, uhura n'ibikenewe byose kuva ku gusya gukomeye kugeza ku gusya neza.

Porogaramu
1. Inganda zikora ibirungo:Ikoreshwa mu gusya no gukwirakwiza ibikoresho fatizo bya ceramic, kunoza ubwinshi n'irangira ry'ibicuruzwa bya ceramic;
2. Inganda zikora amarangi n'amabara:Bifasha gukwirakwiza uduce tw'ibara ry'umukara ku buryo bungana, bigatuma ibara rihoraho kandi rikagira imiterere myiza mu irangi;
3. Gutunganya amabuye y'agaciro:Ikoreshwa nk'uburyo bwo gusya mu gusya neza amabuye y'agaciro, yongera imikorere myiza y'ubuziranenge n'urwego rwo gusya neza;
4. Inganda zikora imiti:Ikoreshwa nk'uburyo bwo gukangura no gusya mu bikoresho bitandukanye bya shimi, iteza imbere uruvange rw'ibintu n'uburyo bikoreshwa;
5. Gukora ibikoresho by'ikoranabuhanga:Ikoreshwa mu gusya no gutunganya ibumba ry'ikoranabuhanga, ibikoresho bya rukuruzi, n'ibindi bice by'ikoranabuhanga bitunganye, byujuje ibisabwa cyane kugira ngo ingano y'uduce n'ubuziranenge bibe byiza.
Umwirondoro w'ikigo
Shandong Robert New Material Co., Ltd.iherereye mu Mujyi wa Zibo, mu Ntara ya Shandong, mu Bushinwa, ikaba ari ikigo gikoreramo ibikoresho birwanya ubukana. Turi ikigo kigezweho gihuza ubushakashatsi n'iterambere, umusaruro, kugurisha, igishushanyo mbonera n'ubwubatsi bw'itanura, ikoranabuhanga, no kohereza mu mahanga ibikoresho birwanya ubukana. Dufite ibikoresho byuzuye, ikoranabuhanga rigezweho, imbaraga zikomeye mu bya tekiniki, ubwiza bw'ibicuruzwa, n'izina ryiza. Uruganda rwacu rukora hegitari zirenga 200 kandi umusaruro w'ibikoresho birwanya ubukana buri mwaka ni toni 30000 naho ibikoresho birwanya ubukana ni toni 12000.
