Ni ibihe bintu bizagira ingaruka ku mucyo wa alumina ceramics?

Imwe mu miterere yingenzi yububumbyi bubonerana nuburyo bwohereza. Iyo urumuri runyuze mu giciriritse, gutakaza urumuri nuburemere bwiyongera bizabaho bitewe no kwinjizwa, kugaragarira hejuru, gutatanya no kugabanuka kwicyerekezo. Iyi attenuations ntabwo ishingiye gusa kumiterere yibanze yimiti yibikoresho, ahubwo biterwa na microstructure yibikoresho. Ibintu bigira ingaruka ku ihererekanyabubasha ryibumba bizatangizwa hepfo.

1.Ubukorikori bwibumba

Gutegura ububumbyi buboneye nibyingenzi kugirango ukureho ubucucike bwa micro-pore muburyo bwo gucumura. Ingano, umubare nubwoko bwa pore mubikoresho bizagira ingaruka zikomeye kumucyo wibikoresho bya ceramic.Ihinduka rito mubyifuzo birashobora guhindura cyane ihererekanyabubasha ryibikoresho. Kurugero, ubushakashatsi bwerekanye ko gukorera mu mucyo bigabanukaho 33% mugihe poritike ifunze mubutaka bwahindutse kuva 0.25% ikagera kuri 0,85%. Nubwo ibi bishobora kuba ibisubizo byikibazo runaka, kurwego runaka, turashobora kubona ko ingaruka zo gutitira kumucyo wibumba ryibumba ari kwigaragaza bitaziguye kandi byubugizi bwa nabi. Andi makuru y’ubushakashatsi yerekana ko iyo ingano ya stomatal ari 3%, ihererekanyabubasha ni 0.01%, naho iyo stomatal ni 0.3%, ihererekanyabubasha ni 10%. Kubwibyo, ububumbyi buboneye bugomba kongera ubwinshi bwabyo no kugabanya ubukana bwabo, ubusanzwe burenga 99.9%. Usibye kuba porotike, diameter ya pore nayo igira uruhare runini mugukwirakwiza ububumbyi. Nkuko bigaragara ku gishushanyo gikurikira, turashobora kubona ko itumanaho ari ryo hasi iyo diameter ya stomata ihwanye nuburebure bwumucyo wurumuri rwabaye.

Ingano y'ibinyampeke

Ingano yubunini bwa ceramic polycrystal nayo igira uruhare runini mu ihererekanyabubasha ryibumba ryera. Iyo ibyabaye urumuri rwumurambararo rungana na diameter yintete, ingaruka zo gukwirakwiza urumuri nini nini kandi ihererekanyabubasha ni rito. Kubwibyo, kugirango tunonosore ihererekanyabubasha ryibumba ryera, ingano yingano igomba kugenzurwa hanze yumurambararo wumucyo wibyabaye.

3. Imiterere yimipaka

Imipaka y'ibinyampeke ni kimwe mu bintu by'ingenzi bisenya ubutunzi bwa optique bwa ceramique kandi bigatera urumuri kandi bikagabanya ihererekanyabubasha ry'ibikoresho. Icyiciro cyibigize ceramic mubusanzwe bigizwe nibice bibiri cyangwa byinshi, bishobora kuganisha byoroshye kumucyo ukwirakwira kumupaka. Ninshi itandukaniro ryibigize ibikoresho, niko itandukaniro ryinshi ryerekana indangantego, kandi niko kugabanuka kwamabuye yose yubutaka.Niyo mpamvu, akarere gahana imbibi zintara zubutaka bwibumba bugomba kuba buke, guhuza urumuri nibyiza, kandi nta pore ihari , ibiyirimo, gutandukana nibindi. Ibikoresho byubutaka hamwe na kristu ya isotropique birashobora kugera kumurongo woherejwe bisa nibirahure.

4. Kurangiza ubuso

Ihererekanyabubasha ryibumba ryibonerana naryo ryibasiwe nubuso bukabije. Ubusumbane bwubutaka bwa ceramique ntabwo bufitanye isano gusa nubwiza bwibikoresho fatizo gusa, ahubwo bufitanye isano no gutunganya imashini yubutaka bwa ceramic. Nyuma yo gucumura, ubuso bwubutaka butavuwe bufite ububobere bunini, kandi gukwirakwiza diffuse bizabaho mugihe urumuri rwabaye hejuru, bikazana gutakaza urumuri. Nubunini bukabije bwubuso, niko kwanduza ibintu.

Ubuso bwubutaka bwubutaka bufitanye isano nubwiza bwibikoresho fatizo. Usibye guhitamo ibikoresho byiza cyane, ibikoresho byubutaka bigomba kuba hasi kandi bigasukurwa. Ihererekanyabubasha rya alumina ryibumba ryibumba rirashobora kunozwa cyane mugusya no gusya. Ihererekanyabubasha rya alumina ryibumba ryibumba nyuma yo gusya rishobora kwiyongera kuva kuri 40% -45% kugeza kuri 50% -60%, kandi gusya bishobora kugera hejuru ya 80%.
