Zirconia Cov Nrig
Zirconium oxide blocks, tseem hu ua zirconium dioxide (zrox), yog ib hom ntaub ntawv siv zirmonia cov ntaub ntawv, thiab tom qab ntawd}
Cov xovxwm hydraulic yog qhov ua tau zoo rau nias zirconia cov khoom lag luam thiab nias tus txheej txheem kom ntseeg tau tias yog qhov zoo tshaj plaws ntawm lub cev thiab cov kev ua tau zoo tshaj plaws {}}
Nias cov yam ntxwv ntawm cov ntaub ntawv zirconia
Khoom Siv Khoom
Zirconia (Zro₂) yog qhov ua tau zoo ceramic nrog lub siab tawv, hnav tsis zoo thiab tshuaj lom neeg feem ntau yuav tsum muaj kev kub ntxhov ntawm lub qhov nthe ntawm lub cev ntsuab.
Kev Tshaj Tawm Xav Tau
Firconia hmoov yuav tsum tau tsim rau hauv cov khaub ncaws hnav thiab lub cev ntsuab ntom ntsuab nyob rau hauv ntau pua ntawm MPa) kom txo porosity tom qab sintering .
Hloov pauv tau ntawm cov xovxwm hydraulic
Siab Ntau Yam
Hydraulic xovxwm tuaj yeem muab siab los ntawm kaum rau txhiab tus tons kom tau raws li cov kab piv txwv zirconium oxide hmoov nrog ib lub cheeb tsam ntawm 50 {}}}}}}
Kev Ntsuas Cov Qauv
Unidirectional / Bidirectional nias: Qhov tsim nyog rau cov khoom noj uas yooj yim, tus nqi qis, tab sis tej zaum yuav tsis muaj qhov sib luag meterity.
ISostatic nias (cov khoom siv tshwj xeeb): muab cov khoom siv tshwj xeeb):
Cov Txheej Txheem Tseem Ceeb
Hmoov pretriceator
Granulation: txhim kho cov fluer, binder (xws li PVA) lossis roj nplua nyeem (xws li zinc stearate) tuaj yeem ntxiv .
Particle Mending: Ua kom zoo tshaj qhov muab faib rau kom ua kom tiav cov ntom ntom nti .
Nias tsis
Siab: feem ntau {{50-200 MPa, nyob ntawm cov hmoov yam ntxwv.
Lub sij hawm nyob: Txog {10-60}} vib nas this kom ntseeg tau tias cov kev ntxhov siab tso {}}
Nias ceev: qeeb nias kom tsis txhob muaj huab cua entrapment .
Pwm Tsim
Cov khoom siv: carbide lossis cuab tam hlau (xws li SKD11), thaj npoo polished kom txo kev txhuam.
Kev sib tshuam: Txog {1-3 degree, yooj yim rau demold .
Shrinkage kev them nyiaj: Feserve sintering shrinkage (feem ntau 15-25%).
Tom Tomining Sintering Txheej Txheem
Sintering kub
txog 1400-1600℃(nyob ntawm theem ntawm zirconium oxide thiab additives) .
Sintering cua
huab cua lossis lub tshuab nqus tsev (kom tsis txhob muaj paug los ntawm kev tsis huv) .
Kaum sensification
Kub nias Sintering (ua ke siab thiab kub ntxiv) tuaj yeem nce cov ntom ntom, tab sis yuav tsum muaj cov khoom tshwj xeeb .
Daim Ntawv Thov Kev Pab Cuam
Tsev kawm txuj ci
Mekas hydraulic presses (xws li 50-100} tons) tuaj yeem ua tau raws li qhov yuav tsum {}}
Muaj Ntau Lawm
Automated Hydraulic cov kab yuav tsum tau, ua ke rau kev pub mis, nias, thiab demoulding ua haujlwm.
