Kev xaiv zoo tshaj plaws rau kev ua haujlwm siab sib tsoo tawm - zirconia hlaws thiab lawv cov ntawv thov
Nyob rau hauv lub tshav pob ntawm high-precision ntub sib tsoo thiab dispersion, qhov kev ua tau zoo ntawm kev sib tsoo xov xwm yog nce. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li lub zog tshiab, electronics, precision ceramics thiab high-end coatings, tsoos sib tsoo xov xwm yuav tsis ua tau raws li cov kev xav tau ntawm ultra-zoo sib tsoo, purity tswj thiab lub zog noj optimization. Lub sijhawm no, zirconia hlaws, raws li hom tshiab ntawm kev ua haujlwm siab ceramic sib tsoo xov xwm, tau maj mam dhau los ua qhov tseem ceeb ntawm kev ua lag luam.
Dab tsi yog zirconia hlaws?
Zirconia hlaws yog me me spheres sintered los ntawm cov khoom ruaj khov zirconia nrog lub zog siab, siab hardness, siab ceev thiab zoo heev hnav tsis kam. Nws cov khoom siv tseem ceeb, zirconia, muaj qhov zoo toughness thiab tshuaj inertness, uas ua rau zirconia hlaws kom muaj kev ruaj ntseg zoo thiab kev pab cuam lub neej nyob rau hauv siab zog ceev, siab shear thiab siab viscosity systems.
Feem ntau hom zirconia hlaws muaj xws li:
Y-TZP stabilized zirconia hlaws dai: doped nrog yttrium oxide, nrog lub siab tshaj plaws ceev thiab hardness, haum rau nano-qib sib tsoo;
ZTA composite zirconia hlaws dai: ua los ntawm alumina thiab zirconia composite, nqi-zoo;
PSZ ib nrab stabilized zirconia hlaws dai: zoo heev toughness, haum rau high-zog ntxhib sib tsoo los yog thawj sib tsoo txheej txheem.
Kev ua tau zoo ntawm zirconia hlaws
Qhov laj thawj yog vim li cas zirconia hlaws tuaj yeem sawv ntawm ntau qhov sib tsoo xov xwm yog vim lawv cov yam ntxwv tseem ceeb hauv qab no:
High ceev (5.8 ~ 6.2 g / cm³): coj ntau dua sib tsoo kinetic zog thiab txhim kho kev sib tsoo efficiency;
High hardness (Mohs hardness ≥8): tsis yooj yim rau hnav, yuav tsis ua rau impurity paug rau cov khoom sib tsoo;
High toughness: tsis yooj yim rau tawg txawm nyob rau hauv high-siv kev cuam tshuam, xyuas kom meej sib tsoo stability;
Tus nqi qis qis: poob qis ntawm cov hlaws me me hauv ib lub sijhawm, ncua kev pabcuam lub neej;
Smooth nto thiab siab sphericity: smoother ua haujlwm, txo cov khoom siv thiab siv zog.
Ntau yam kev siv
Zirconium oxide hlaws tuaj yeem siv dav hauv ntau yam khoom sib tsoo ntub dej (xws li kab rov tav xuab zeb zeb, nplawm mills, pob tawb grinders, thiab lwm yam), thiab lawv cov ntawv tshwj xeeb suav nrog tab sis tsis txwv rau:
Cov khoom siv hluav taws xob tshiab: sib tsoo ntawm lithium hlau phosphate, cov ntaub ntawv ternary, silicon-carbon tsis zoo electrodes, thiab lwm yam .;
Cov khoom siv ua haujlwm siab: siv rau cov hmoov ua kom zoo ntawm txhuas oxide, silicon nitride, silicon carbide, thiab lwm yam.;
Electronic chemical cov ntaub ntawv: xws li ITO conductive iav slurry, MLCC ceramic hmoov, thiab lwm yam.;
High-end txheej inks: homogeneous dispersion ntawm UV inks, nano txheej, thiab hluav taws xob inks;
Tshuaj thiab zaub mov: siv rau kev sib tsoo-dawb micronization hauv biopharmaceuticals thiab khoom noj khoom haus.
Cov ntsiab lus
Raws li ib qho kev sib tsoo nruab nrab uas ua ke nrog lub zog siab, siab purity thiab siab ruaj khov, zirconia hlaws tau dhau los ua cov khoom tseem ceeb rau ntau yam kev lag luam los txhim kho hmoov raug, ruaj khov cov txheej txheem ntau lawm, thiab txhim kho cov nqi tsim khoom. Nrog rau kev nce qib ntawm kev tsim khoom thiab kev tsim ntsuab, zirconia hlaws yuav ua lub luag haujlwm tseem ceeb hauv kev sib tsoo ntub dej yav tom ntej.
