3) Txheej Kev Lag Luam: Sau rau cov txheej txheem tshwj xeeb thiab cov ntshav txau.
4) Kev lag luam hlau thiab cov khoom lag luam Ceramic: sintered ceramic raw cov ntaub ntawv, kub tiv taus cov txheej txheej, thiab lwm yam.
Cov Abrasive Polishing kua
Piv nrog cov pa nano-alumina, lub tiaj thiab du daim ntawv saum npoo tsis yooj yim rau khawb cov khoom uas muaj zog, thiab cov khoom lag luam tsim nyog tuaj yeem nce 10% mus rau 15%. Yog li ntawd, phaj-puab alumina tau dhau los ua qhov tshiab ntawm lub siab-precision microelectronics kev lag luam, lub pov haum kev lag luam thiab kev lag luam kev lag luam ceramic.
Inorganic fillers
Lub phaj alumina yog ib qho tsis tseem ceeb rau kev tsim khoom hauv kev lag luam. Nws yog siv nyob rau hauv cov khoom siv ua haujlwm, cov ntaub yas thiab cov roj hmab kom nce hardness thiab rigidity, thiab tuaj yeem hloov shrinkage thiab thermal nthuav coefficients.
Ua Haujlwm Txheej
Cov zoo heev phaj-zoo li txhuas oxide tsis muaj agglomeration prenomenon thiab zoo adhesion. Nws yog ib qho yooj yim los ua ke nrog lwm cov haujlwm micropowders los npaj ntau yam khoom siv tau zoo nkauj nrog cov khoom txaus nyiam. Cov txheej txheem oxide txhuas siv rau cov hlab ntsha tuaj yeem txhim kho nws cov kev thim rov qab ntawm electroososmotic txaus thiab kev xaiv tau thiab kev ruaj ntseg ntawm lub hom phiaj tsom xam; Lub tshuab ua haujlwm tau siv rau lub dav hlau stealth tuaj yeem nqus tau xov tooj cua tsis tuaj yeem tshawb nrhiav los ntawm radar.
Saciconductor wafer tiaj tus Alumina Polishing Hmoov Tej yam
1. Cov platelet pamined alumina hmoov tsim los ntawm Bingyang Abrasive tuaj yeem ua tiav cov nyhuv sib tsoo ntawm cov ntawv sib tsoo-zoo li txhuas oxide hmoov piv rau cov khoom lag luam txawv teb.
2. Lub Crystal daim ntawv yog ca yam tsis muaj npoo thiab lub sij hawm sib tsoo, cov abrasive tau ua ib qho kev ua haujlwm tiaj tus, ua rau nws khawb.
3. Siab tawv thiab muaj zog sib tsoo quab yuam. Flaky Alumina muaj cov khoom zoo sib xws rau Corundum - Al2o3 Crystal theem, haum rau kev sib tsoo thiab polishing ntawm cov ntaub ntawv feem ntau.
4. Tsawg cov ntsiab lus sib nqus, muaj kev huv huv, thiab qhov siab siab qhov loj me me.
5. Muaj siab melting taw tes, muaj lub zog txhua yam, thiab kev sib tsoo siab zoo.
6. Lub particle loj yog tswj tau thiab tuaj yeem tau txais los ntawm 3 mus rau 50 microns.
7. Lub flatness ntawm cov lus ua kom tus nplaim taws yooj yim rau kev tawg yooj yim rau kev tawg, ua rau cov kua dej sib tsoo.
8. Nws muaj corrosion tsis kam, tshuaj lom neeg muaj zog ruaj khov, thiab zoo tshaj antioxidant kev ua tau zoo, thiab yuav tsis muaj kev tawm tsam nrog kua media hauv cov kua sib tsoo.
9. Thaj chaw tshwj xeeb thaj av, cov dej num nto thiab cov nplaum vim muaj zog polishing zog.
10. Plateleled alumin hmoov yog ib qho yooj yim rau disperse, thiab cov hmoov tsis yooj yim rau saum npoo ntawm cov wafer, ua rau muaj kev cuam tshuam thiab cuam tshuam rau polishing smoothness.
