Kev xaiv zoo tshaj plaws rau kev sib tsoo ua haujlwm siab - zirconia hlaws dai thiab lawv daim ntawv thov
Hauv kev sib tsoo ntub thiab kev sib cais siab, qhov yuav tsum tau ua rau cov khoom sib tsoo ntau ntxiv. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li lub zog tshiab, hluav taws xob, cov khoom siv ceramic thiab cov txheej txheem siab, cov khoom sib tsoo ib txwm tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev sib tsoo zoo heev, kev tswj kev huv thiab kev siv hluav taws xob zoo dua. Lub sijhawm no, cov hlaws zirconia, ua ib hom tshiab ntawm cov khoom sib tsoo ceramic siab, maj mam dhau los ua qhov tseem ceeb ntawm kev ua lag luam.
Cov hlaws zirconia yog dab tsi?
Cov hlaws zirconia yog cov pob me me uas tau sintered los ntawm cov khoom siv zirconia ruaj khov heev nrog lub zog siab, siab tawv, siab ceev thiab zoo heev hnav tsis kam. Nws cov khoom siv raw tseem ceeb, zirconia, muaj kev tawv zoo thiab tshuaj inertness, uas ua rau cov hlaws zirconia kom tswj tau qhov ruaj khov zoo thiab lub neej ua haujlwm hauv cov txheej txheem siab zog, siab shear thiab siab viscosity.
Cov hom zirconia feem ntau muaj xws li:
Y-TZP stabilized zirconia hlaws dai: doped nrog yttrium oxide, nrog qhov ceev tshaj plaws thiab hardness, tsim rau nano-level sib tsoo;
ZTA composite zirconia hlaws dai: ua los ntawm alumina thiab zirconia composite, pheej yig;
PSZ ib feem ruaj khov zirconia hlaws dai: zoo heev toughness, haum rau high-energy coarse sib tsoo lossis thawj zaug sib tsoo cov txheej txheem.
Kev ua tau zoo ntawm cov hlaws zirconia
Qhov laj thawj vim li cas zirconia hlaws dai tuaj yeem sawv tawm ntawm ntau cov xov xwm sib tsoo yog vim lawv cov yam ntxwv tseem ceeb hauv qab no:
Qhov ceev ceev (5.8 ~ 6.2 g / cm³): coj lub zog kinetic sib tsoo siab dua thiab txhim kho kev sib tsoo zoo;
Kev nyuaj siab (Mohs hardness ≥8): tsis yooj yim hnav, yuav tsis ua rau muaj kev sib kis ntawm cov khoom sib tsoo;
Kev tawv siab: tsis yooj yim tawg txawm tias nyob rau hauv qhov cuam tshuam siab, ua kom muaj kev sib tsoo ruaj khov;
Tus nqi hnav qis: poob me me ntawm cov hlaws dai ib lub sijhawm, ua rau lub neej ua haujlwm ntev dua;
Qhov nto du thiab lub voj voog siab: kev ua haujlwm du dua, txo cov khoom siv hnav thiab kev siv zog.
Ntau yam kev siv
Cov hlaws zirconium oxide tuaj yeem siv dav hauv ntau yam khoom siv sib tsoo ntub (xws li cov xuab zeb kab rov tav, cov tshuab sib xyaw, cov tshuab sib tsoo pob tawb, thiab lwm yam), thiab lawv cov ntawv thov tshwj xeeb suav nrog tab sis tsis txwv rau:
Cov ntaub ntawv siv zog tshiab: kev sib tsoo ntawm lithium hlau phosphate, cov ntaub ntawv ternary, silicon-carbon negative electrodes, thiab lwm yam.;
Cov khoom siv ua los ntawm cov khoom siv ceramics zoo: siv rau kev ua kom zoo ntawm cov hmoov txhuas oxide, silicon nitride, silicon carbide, thiab lwm yam.
Cov ntaub ntawv tshuaj lom neeg hluav taws xob: xws li ITO conductive iav slurry, MLCC ceramic hmoov, thiab lwm yam.;
Cov kua mem pleev xim zoo tshaj plaws: kev sib xyaw ua ke ntawm UV kua mem, nano txheej, thiab cov kua mem hluav taws xob;
Tshuaj thiab khoom noj: siv rau kev sib tsoo micronization uas tsis muaj kuab paug hauv biopharmaceuticals thiab cov khoom noj muaj txiaj ntsig.
Kev Txheeb Xyuas
Ua ib qho khoom siv sib tsoo siab heev uas muaj zog heev, purity siab thiab ruaj khov, zirconia hlaws dai tau dhau los ua ib qho khoom siv tseem ceeb rau ntau yam lag luam los txhim kho qhov tseeb ntawm hmoov, ruaj khov cov txheej txheem tsim khoom, thiab ua kom zoo dua cov qauv nqi. Nrog rau kev nce qib tas mus li ntawm kev tsim khoom raug thiab kev tsim khoom ntsuab, zirconia hlaws dai yuav ua lub luag haujlwm tseem ceeb hauv kev siv sib tsoo ntub yav tom ntej.
