Dab tsi yog cov txheej txheem tsim khoom ntawm zirconia ceramic pob?

1. Direct pyrolysis txoj kev
Txoj kev ncaj qha pyrolysis yog tsim rau kev npaj ntawm zirconia ceramic pellets los ntawm cov hlau carbonates. Nws tsis tsuas yog siv tag nrho cov ntaub ntawv raw, tab sis kuj yog ib puag ncig tus phooj ywg; Cov txheej txheem yog yooj yim thiab haum rau industrial loj ntau lawm. Zirconia npas Cov kauj ruam tseem ceeb hauv cov txheej txheem yog calcination, thiab cov thermal decomposition cov tshuaj tiv thaiv ua rau muaj roj ntau, uas yuav tsum tau ua kom sov maj mam.
Thib ob, txoj kev txhaj tshuaj molding
Cov txheej txheem molding yog ib txoj kev siv dav hauv molding, thiab qhov zoo ntawm zirconia pob txheej txheem yog kev ua haujlwm siab thiab ua haujlwm yooj yim; Lub firing shrinkage ntawm cov khoom yog me me thiab tsis yooj yim rau deform. Qhov tsis zoo yog qhov loj ntawm lub pob zirconia loj thiab cov duab kheej kheej tsis zoo. Cov txheej txheem molding feem ntau yog siv los npaj cov khoom siv plooj (porcelain) yooj yim hauv cov duab ntawm cov rods thiab txhua kab lossis discs, thiab muaj cov kev xav tau siab rau qhov zoo ntawm cov pwm. Yog tias cov khoom me me ceramic tau npaj, qhov ua tau zoo yog tsawg.
3. Rov qab-theem ncua kev kawm ntawv polymerization
Suspension polymerization yog hais txog cov txheej txheem ntawm polymerizing lub monomer nyob rau hauv daim ntawv ntawm cov tee thiab dispersing cov neeg sawv cev los ntawm cov neeg kho tshuab stirring thiab dispersant. Lub kaw lus ntawm zirconia npas feem ntau yog tsim los ntawm plaub ntu: monomer, roj-soluble pib, dej thiab dispersant. Reversed-phase suspension polymerization yog polymerization ntawm dej-soluble monomers hauv cov organic hnyav los ntawm dispersing lawv mus rau hauv cov dej zoo.
