Gutegura Ikoranabuhanga rya Alumina Ceramics (2)

gukanda

Uburyo bwumye bwo gukanda

Alumina ceramictekinoroji yo gukanda yumye igarukira kumiterere yera kandi uburebure bwurukuta burenze 1mm, uburebure bwa diameter ntabwo burenze ibicuruzwa 4∶1.Uburyo bwo gushiraho ni uniaxial cyangwa biaxial.Imashini ifite hydraulic, imashini yubwoko bubiri, irashobora kuba igice cyikora cyangwa cyikora.Umuvuduko ntarengwa wibinyamakuru ni 200Mpa, kandi ibisohoka birashobora kugera kuri 15 ~ 50 kumunota.

Bitewe numuvuduko umwe wa stroke ya hydraulic, uburebure bwibice byo gukanda buratandukanye iyo kuzuza ifu bitandukanye.Nyamara, umuvuduko ukoreshwa nubushakashatsi bwa mashini uratandukanye nubunini bwuzuye ifu, bizaganisha byoroshye itandukaniro ryo kugabanuka kwubunini nyuma yo gucumura kandi bigira ingaruka kumiterere yibicuruzwa.Kubwibyo, gukwirakwiza ifu yifu muburyo bwo gukanda byumye ningirakamaro cyane mukuzuza ibumba.Niba umubare wuzuye wuzuye cyangwa udafite uruhare runini mugucunga neza ibipimo bya alumina ceramic yakozwe.Ingaruka ntarengwa yubusa irashobora kuboneka mugihe ifu yifu irenze 60μm no hagati ya mesh 60 ~ 200, kandi ingaruka nziza yo gushiraho umuvuduko irashobora kuboneka.

Uburyo bwo gushushanya

Gutegura gushushanya nuburyo bwambere bwo kubumba bukoreshwa murialumina ceramics.Bitewe no gukoresha gypsum mold, igiciro gito kandi byoroshye gukora ubunini bunini, ibice byimiterere bigoye, urufunguzo rwo gushushanya ni ugutegura alumina.Mubisanzwe hamwe namazi nkibikoresho bya flux, hanyuma ukongeramo imiti yo gushonga hamwe na binder, byuzuye nyuma yo gusya umuyaga, hanyuma ugasuka mubibumbano.Bitewe na adsorption yamazi na capillary yububiko bwa gypsumu, ibishishwa birakomera mubibumbano.Gutobora ubusa, murukuta rwubatswe adsorption yubushyuhe bugera kubisabwa, ariko kandi bigomba gusuka ibishishwa birenze.Kugirango ugabanye kugabanuka kwumubiri, hagomba gukoreshwa ibinure byinshi cyane bishoboka.

Inyongeramusaruro zigomba kongerwaho kurialumina ceramicguhubuka kugirango habeho amashanyarazi abiri hejuru yubutaka bwa slurry kugirango ibishishwa bishobora guhagarikwa neza nta mvura igwa.Byongeye kandi, birakenewe kongeramo inzoga za vinyl, methyl selulose, alginate amine nizindi binder na polypropilene amine, gum yicyarabu nizindi zikwirakwiza, ikigamijwe ni ugukora ibishishwa bikwiranye nigikorwa cyo gusya.

Ikoranabuhanga

Uburyo bwa tekiniki bwo kugabanya umubiri wa ceramic ceramic no gukora ibintu bikomeye byitwa gucumura.Gucumura nuburyo bwo kuvanaho icyuho kiri hagati yumubiri wa bilet, ukuraho gaze nkeya hamwe n umwanda mubintu kama, kugirango ibice bikure hamwe bigire ibintu bishya.

Igikoresho cyo gushyushya gikoreshwa mu kurasa muri rusange ni itanura ry'amashanyarazi.Usibye gucumura k'umuvuduko usanzwe, ni ukuvuga, nta gucumura k'umuvuduko, gushyushya gukanda no gushyushya isostatike.Gukomeza gushyuha birashobora kongera umusaruro, ariko igiciro cyibikoresho nububiko ni byinshi cyane, hiyongereyeho uburebure bwibicuruzwa ni bike.Umuvuduko ukabije wa isostatike ushiramo ubushyuhe bwo hejuru hamwe na gaze yumuvuduko mwinshi nkumuyoboro wohereza umuvuduko, ufite ibyiza byo gushyushya kimwe mubyerekezo byose, kandi birakwiriye gucumura ibicuruzwa bigoye.Kubera imiterere imwe, imiterere yibikoresho yiyongereyeho 30 ~ 50% ugereranije no gukonjesha gukonje.10 ~ 15% hejuru kurenza ibisanzwe bishyushye bikanda.
