Zirconia, cov khoom siv tseem ceeb ceramic, yog siv dav hauv kev lag luam vim nws cov khoom zoo xws li lub zog siab, hnav tsis kam, thiab kub tsis kam. Nws cov txheej txheem npaj muaj ob peb kauj ruam tseem ceeb, suav nrog kev npaj raw khoom, sib tov, molding, sintering, thiab tom qab- kho. Hauv qab no yog cov lus piav qhia ntxaws txog txheej txheem kev npaj zirconia.
1. Raw Material Preparation: Lub ntsiab raw khoom rau zirconia yog zirconia hmoov, uas feem ntau tau los ntawm zirconia ore los ntawm crushing thiab sib tsoo. Kev soj ntsuam nruj nruj yog qhov tseem ceeb nyob rau theem no, yuav tsum muaj kev ntsuam xyuas meej ntawm cov ntsuas tseem ceeb xws li particle loj tis thiab tshuaj muaj pes tsawg leeg kom ntseeg tau tias cov khoom siv raw ua tau raws li cov qauv tsim.
2. Kev sib xyaw: Qhov zoo- tshuaj xyuas zirconia hmoov yog sib xyaw kom huv si nrog cov stabilizers, plasticizers, thiab lwm yam additives nyob rau hauv ib qho piv txwv. Cov txheej txheem sib xyaw yog txhawm rau txhim kho cov molding thiab sintering cov khoom ntawm zirconia ceramics, yog li muab lawv zoo tshaj plaws physicochemical zog.
3. Moulding: Cov hmoov sib xyaw zirconia yog molded siv cov cuab yeej nias. Cov txheej txheem molding feem ntau suav nrog kev nias qhuav thiab txhaj tshuaj molding. Thaum lub sij hawm molding txheej txheem, cov txheej txheem molding uas tsim nyog tshaj plaws yuav tsum raug xaiv raws li cov qauv thiab qhov loj ntawm cov khoom kom ntseeg tau tias qhov tseeb thiab qhov chaw tiav ntawm cov pwm ua tau raws li cov qauv xav tau.
4. Sintering: Lub zirconia blanks tom qab molding yuav tsum undergo sintering. Sintering yog ib qho txheej txheem tseem ceeb uas txhawb nqa kev loj hlob siv lead ua nyob rau hauv qhov khoob ntawm qhov kub thiab txias, tsim cov qauv ntom ntom. Nws yog tsim nyog sau cia tias yam xws li sintering kub, lub sij hawm, thiab huab cua muaj feem xyuam rau kev ua tau zoo ntawm zirconia ceramics; Yog li ntawd, cov txheej txheem sintering tsim nyog yuav tsum tau ua tib zoo tsim raws li cov kev cai tshwj xeeb ntawm cov khoom.
5. Tom qab-kev kho mob: Tom qab sintering, zirconia ceramic cov khoom tau dhau los tom qab- cov txheej txheem kho, suav nrog polishing nto, tu, thiab tshuaj xyuas. Cov ntawv tshaj tawm no - cov txheej txheem kho tau zoo txhim kho qhov zoo ntawm qhov chaw thiab cov txiaj ntsig ntawm zirconia ceramic khoom, kom ntseeg tau tias cov khoom kawg ua tau raws li cov qauv kev xav tau los ntawm cov neeg siv khoom.
Cov saum toj no yog ua tiav cov txheej txheem ntawm zirconia. Los ntawm kev tsim qauv zoo thiab kev tswj hwm nruj ntawm txhua kauj ruam, suav nrog kev npaj cov khoom siv raw, sib tov, molding, sintering, thiab tom qab- kev kho mob, siab -kev ua tau zoo zirconia ceramic khoom tuaj yeem npaj tau zoo, yog li ua tau raws li kev xav tau ntawm ntau hom kev lag luam sib txawv. Hauv kev tsim khoom tiag tiag, kev hloov kho thiab kev ua kom zoo yuav tsum tau ua kom yooj yim raws li cov khoom siv tshwj xeeb thiab cov txheej txheem txheej txheem txhawm rau txhawm rau txhim kho cov khoom zoo thiab kev ua haujlwm zoo.
