Igikoresho cya Alumina Ceramic kidasharira gikoreshwa mu bikoresho by'uruganda rwa sima

Mu gukora sima, ibikoresho nk'imiyoboro itwara ibikoresho, imiyoboro igabanya ubushyuhe, inkubi z'umuyaga, n'imiyoboro bimara igihe kirekire bihura n'ingaruka zikomeye z'umuvuduko mwinshi no kwangirika, bigatuma ibyuma bitakaza vuba kandi ikiguzi cyo kubungabunga kiyongera. Gukoresha umugozi wa alumina udashira byongerera igihe ubuzima bwo gukora. Uyu mugozi ukorwa binyuze mu gushyuha cyane, ufite alumina itari munsi ya 92%, ubucucike bw'umuzingo ≥3.60 g/cm³, ubukana bwa Rockwell (HRA) buri hejuru ya 85, n'ingano y'ubusaza iri munsi ya 0.1 cm³ (byageragejwe hakurikijwe GB/T 8489-2006).

Ugereranije n'ibyuma bisanzwe bidashira (urugero, NM400), icyuma gikozwe muri alumina ceramic gifite ubushobozi bwo kudashira inshuro zigera kuri 5-8, hamwe n'ubushobozi bwo gushwanyagurika ku buso buke (hafi 0.2-0.3 mu gihe cy'umuvuduko), bigabanya ibyago byo gufatana kw'ibikoresho no kuziba. Amatafari ya ceramic ashyirwa ku rukuta rw'imbere rw'ibikoresho hakoreshejwe epoxy resin cyangwa kole idakora, afite ubushyuhe buri hagati ya -50°C na 300°C kandi yihanganira igihe gito kugeza kuri 500°C. Mu gihe cy'imiterere isanzwe y'uruganda rwa sima, icyuma gikozwe muri ceramic cyongera igihe cyo gukora kuva ku mezi 6 kugeza ku mezi arenga 36.

Iyi nyunganiramirire yakoreshejwe neza ku bice by'ingenzi nka za feri zikoreshwa mu nganda, ibyuma bitandukanya ibikoresho, ibyuma bifunga imiyoboro ya cyclone, n'imiyoboro itwara icyuma mu nganda za sima. Amakuru y'ubutaka agaragaza ko munsi y'ingano y'uduce tw'ibikoresho bya mm 30 n'umuvuduko wa metero 15/s, nyuma y'amezi 12 y'imikorere idasibangana, uburebure bw'ubujyakuzimu ku buso bw'amatafari ya ceramic ari mm 0.2–0.5 gusa, kandi igihe cyo kubungabunga ibikoresho cyongerewe inshuro enye z'igihe cyagenwe. Iboneka mu mabati ya ceramic cyangwa mu mabati ya mosaic, nyunganiramirire ihinduka ku bikoresho bifite imiterere itandukanye n'imiterere y'imiterere.

Kwamamazaigitambaro cya alumina ceramic kidashira mu bikoresho by'ubuhanga bya simabigabanya neza ikoreshwa ry'ibice bisimbura ibindi n'igihe cyo kuruhuka, bikongera igipimo rusange cy'imikorere y'imirongo ikora. Mu gihe cyo gushyiraho, menya neza ko ubuso bw'ubutaka busukuye kandi nta mavuta arimo; igihe cyo gukoropa gikwiye kuba amasaha 24 (kuri 25°C). Ku nguni z'inkuba zirenze 45° ku hantu hagwa ibikoresho, ni byiza gushyiraho urwego rwa buffer kugira ngo wongere ubushobozi bwo kurwanya inkuba. Iri koranabuhanga ryashyizwe mu bipimo byinshi byo gushushanya uburyo bwo kurinda inkuba mu nganda za sima.
