Cov hniav ua tshuab ntxhua khaub ncaws zirconia thaiv

 

1. Cov ntaub ntawv ntawm kev kho hniav Zirconia block
Kev kho hniav zirconia cov blocks feem ntau yog siv cov zirconium dioxide (zro₂), lub siab-zog, bioocompe tej hub ntawv. Cov ntaub ntawv nyoos tseem ceeb muaj:

High-Purity Zirconium Dioxide Hmoov (3Y-TZP 4Y / 5Y-TZP)
3y-tzp (3 mol% yttria-stabilized tetragonal zirconia polycrystal) muaj siab zog thiab kav ntev.
4Y / 5Y-TZP muab cov lus translucency rau kev kho hniav anteror.
YTTRIA (Y₂O₃) - Ua raws li lub stabilizer kom zirconia hauv tetragonal theem thiab txhim kho borragonal.
Alumina (al₂o₃) - txhim kho kev ruaj khov thiab tiv thaiv kev laus.
Lwm yam kab tawm oxides - kho cov tsis zoo, hute thiab cov neeg kho tshuab.

 

 

Cov yam ntxwv ntawm cov hniav ua tshuab ntxhua khaub ncaws zirconia block:
Lub zog siab thiab cov fracture kuj (3y-tzp rau cov hniav posterior, 5y-tzp rau sab hauv cov hniav)
Zoo nkauj biocompatibility (haum rau kev siv ntev ntev)
Ntuj translucency thiab zoo nkauj (multi-fawm-feathered zirconium oxide cov mimics ntuj cov txha hniav laus)
Tsawg me me hnav ntawm cov hniav rov qab (optimized microstructure)
Tau tshaj cad / cam milling tshuab

Kev tsim kho kab mob hniav Zirconia
Kauj ruam 1: Cov khoom npaj ua khoom
Zirconium dioxide hmoov yog precisely sib xyaw nrog yttrium oxide thiab lwm yam stabilizers kom ua tiav qhov sib npaug zoo ntawm lub zog thiab kev txhais khoom.
Cov hmoov sib xyaw yog cov pob-milled lossis dav hlau-milled kom ua tiav ultra-zoo particle loj kom ntseeg tau tias muaj kev sib luag.
Kauj ruam 2: Txau kom qhuav thiab ziab
Hmoov zoo zirconia hmoov yog ua tiav los ntawm cov tshuaj tsuag kom qhuav rau cov tshuaj dawb-ntws tawm cov lus sib dhos.
Cov kauj ruam no nce cov tuab ntom ntom ntawm cov khoom siv rau kev sib dhos sib xws thaum nias.
Kauj ruam 3: Khaub thuas isostatic nias (CIP)
Qhov zirconium oxide tau muab tso rau hauv cov pwm thiab txias isostatically tau nias (CIP) ntawm kev kub siab (txog 200 MPA).
Qhov no ua kom muaj kev faib tawm ntom ntom ntom ntom ntom, txo kev puas tsuaj sab hauv thiab txhim kho kev siv tshuab zog.
Kauj Ruam 4: Ua Ntej-Sintering
Cov nias zirconia cov blocks yog ua ntej-sintered nyob ib ncig ntawm {1}}} degree kom tau txais lub zog txaus rau milling thaum tswj kev ua haujlwm machinity.
Nyob rau theem no, cov khoom siv yog nyob rau hauv ib cheeb tsam pej xeem hauv xeev thiab tuaj yeem ua tau yooj yim hauv CAD / cam milling tshuab.
Kauj ruam 5: Shaping thiab Machining
Lub ntsej muag pre-sintered yog precisely txiav mus rau hauv cov qauv ntau dua (piv txwv li 98 hli discs) tau tshaj {2}} Axis milling tshuab.
Cov npoo yog tus thiab cov npoo yog kho kom zoo rau kev tuav yooj yim.
Kauj Ruam 6: Kawg Sintering
Tom qab milling mus rau txoj kev kho hniav uas xav tau (yas, thiab lwm yam), 450-1, 600 degree.
Thaum lub sijhawm tus txheej txheem no, zirconia shrinks txog li 20-25% thiab mus txog qhov kawg high-density xeev nrog lub zog ntawm {2}} (3y-tzp muaj lub zog siab dua).
Kauj ruam 7: Coloring thiab Glazing (Xaiv tau)
Coloring: Qee cov zirconia cov blocks yog ua ntej xim, thaum lwm tus yuav tsum tau kua xim ua ntej kev sintering kawg.
Glazing thiab POLISHING: Kev kho tiav tiav yog glazed thiab polished los txhim kho kev zoo nkauj thiab smoothness.
