(Alumina CeramicTsim los ntawmWintrustek)
Aluminayog ib lub npe nquag rau txhuas oxide (Al2O3). Nws yog cov khoom siv hluav taws xob ruaj khov nrog kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob thiab hluav taws xob. Nws yog tsim rau ntau yam kev lag luam siv.
Core Advantages:
Kev tsim khoom: Los ntawm hmoov mus rau Hard Ceramic
Kev tsim khoom zooalumina ceramic khoomMuaj kev hloov pauv ntawm lub cev thiab tshuaj lom neeg:
Kev npaj hmoov: Alumina hmoov yog tov nrog additives (xws li sintering aids).
Txheej Txheem: Qhuav nias, isostatic nias, txhaj tshuaj molding, los yog daim kab xev casting raug xaiv nyob ntawm seb cov duab xav tau.
Sintering:Cov khoom raug rho tawm haujlwm hauv qhov cub kub kub ntawm 1600 ° C mus rau 1800 ° C, ua rau cov hmoov hmoov sib txuas rau hauv cov qauv crystalline ntom ntom.
Ua tiav:Vim nws tsis tshua muaj siab hardness, ua tiav tom qab sintering feem ntau yuav tsum tau siv cov cuab yeej pob zeb diamond los yog sib tsoo log.
Kab lus no tsom mus rau ntau yam kev tsim cov txheej txheem tseem ceeb:
1. Qhuav nias
Qhov no yog txoj kev siv ntau tshaj plaws hauv kev tsim khoom, tshwj xeeb tshaj yog tsim rau kev tsim khoom loj ntawm cov duab yooj yim (xws li nplooj ntawv, rings, thiab ntxhua khaub ncaws).
Txoj Cai:Cov hmoov uas muaj cov ntawv khi yog muab tso rau hauv cov pwm hlau thiab raug rau unidirectional lossis bidirectional siab siv lub xovxwm.
Qhov zoo: Kev ua haujlwm yooj yim, kev ua haujlwm siab, qhov tseeb ntsuab lub cev qhov ntev, thiab yooj yim tswj tau sintering shrinkage.
Kev txwv:Yooj yim rau kev tsim cov khoom sib xws; vim muaj kev sib txhuam quab yuam, qhov ntom ntawm qhov loj yuav tsis sib npaug.
2. Isostatic nias
For high-performance parts requiring high density and uniformity, isostatic pressing is the preferred method.
Txoj Cai: Cov hmoov yog muab kaw rau hauv cov pwm elastic (feem ntau yog ib lub hnab roj hmab) thiab muab tso rau hauv lub nkoj uas muaj kev kub ntxhov, siv cov kua ua kua los ntawm qhov nruab nrab siab.
Core Advantages: Lub siab yog siv uniformly rau cov hmoov los ntawm tag nrho cov kev taw qhia, uas ua rau ib tug zoo sib xws ceev ceev thoob plaws hauv lub cev ntsuab thiab tsawg deformation tom qab sintering.
Daim ntawv thov:Feem ntau siv rau hauv kev tsim cov raj loj ceramic, spheres, lossis precision ceramic bearings.
3. Daim kab xev Casting
Yog tias koj pom ultra-thin ceramic substrates (xws li lub rooj sib tham hauv xov tooj ntawm tes), lawv feem ntau yuav tsim los ntawm daim kab xev casting.
Txoj Cai:Hmoov yog tov nrog cov kuab tshuaj, dispersant, thiab binder los ua ib tug "slurry," uas yog ces kis mus rau ib tug conveyor siv siv ib tug kws kho hniav hniav los ua ib tug nyias zaj duab xis. Cov zaj duab xis yog ces qhuav thiab tev tawm.
Qhov zoo: Muaj peev xwm ntawm kev tsim ultra-thin ceramic nplooj ntawv nrog thicknesses ntawm 10 μm thiab 1 hli.
Daim ntawv thov:Thick-film Circuit Court substrates, multilayer ceramic capacitors (MLCC).
4. Txhaj Moulding
Cov txheej txheem no, qiv los ntawm kev lag luam yas, yog siv los tsim cov khoom nrog cov geometry nyuaj heev.
Txoj Cai:Alumina hmoov yog tov nrog ib tug loj npaum li cas ntawm cov organic binder (txog li 40%), rhuab, thiab txhaj rau hauv ib tug precision pwm, ces txias thiab solidified.
Kev sib tw:Cov txheej txheem "debinding" (tawm cov organic teeb meem) ua ntej sintering yog qhov ntev heev thiab tseem ceeb heev; Kev tuav tsis raug tuaj yeem ua rau tawg yooj yim.
Daim ntawv thov:Ceramic precision qhov chaw, cov khoom siv kho mob.
5. Additive Manufacturing (3D Printing)
Qhov no yog ib qho kev siv thev naus laus zis hauv xyoo tas los no uas rhuav tshem tag nrho cov kev txwv los ntawm cov pwm ntawm cov duab.
Cov txheej txheem tseem ceeb muaj xws li: Stereolithography (SLA) los yog paste extrusion.
Qhov zoo: Tsis tas yuav tsum muaj pwm, ua kom nws tsim nyog rau kev tsim cov qauv lossis tsim cov khoom siv ceramics nrog cov txheej txheem sab hauv (xws li biomimetic skeletons thiab microfluidic chips).
