Aluminium oxide polishing hmoov?

Cov txheej txheem sab nrauv yog qhov tseem ceeb hauv kev tsim khoom lag luam, uas muaj tshuaj kho kom zoo nkauj thiab cov khoom siv hluav taws xob tsis zoo thiab muab cov khoom siv hluav taws xob tseem ceeb thiab muab cov khoom siv hluav taws xob tseem ceeb thiab muab cov khoom siv hluav taws xob tseem ceeb thiab muab cov khoom siv hluav taws xob tseem ceeb thiab muab cov khoom siv hluav taws xob zoo siab thiab cov khoom siv hluav taws xob tsis txaus ntseeg.Alumina polishing hmoovyog ib tug abrasive dav siv nyob rau hauv precision polishing, haum rau piishing ntawm ntau yam ntaub ntawv xws li hlau, iav, catamiconductors, thiab lwm yam.

Kev faib tawm Alumina Polishing Hmoov:

{{0 {}} Raws li cov qauv siv lead ua qauv

• -Alumina (corundum): kub siab ruaj khov me me, siab tshaj plaws, haum rau sapphire thiab hlau polishing .

• -Alumina: thaj chaw tshwj xeeb thaj av tshwj xeeb, kev ua haujlwm siab, haum rau tshuaj kho tshuab polishing (CMP) {1}.

• Sib xyaw Alumina: Ua kom zoo ua kev ua tau zoo los ntawm doping kev hloov kho (xws li cr, si) .

2. los ntawm particle loj

3.} los ntawm purity

• Muaj qib kawm (ntau dua lossis sib npaug nrog 99%): Cov hlau sib luag, iav polishing .

• Qib siab purity (ntau dua los yog sib npaug ntawm 99 {. 9%): Lub lens kho qhov muag, hluav taws xob ceramics.

• Qib-siab huv qib (ntau dua los yog sib npaug rau 99 {. 99%): semiconductor wafers, coj substrates, coj substrates.

Cov txheej txheem npaj ntawm alumina Polishing Hmoov:

Khoom Siv Raw Khoom

• Cov txheej txheem Bayer: Extract high-purity alumina los ntawm bauxite.

• Sol-gel Txoj Kev: Npaj nano-alumina nrog uniform particle loj faib.

Kev xam pom thiab kev faib tawm

• High-temperature calcination (>1200 Qib): Tsim -alumina .

• Cov pa hloov milling: tswj qhov loj me thiab tsis txhob agglomeration .

Kev hloov kho deg deg deg

• Kev ntsuas cov neeg ua haujlwm uas ua haujlwm ruaj khov

Daim ntawv thov alumina Polishing Hmoov:

1. semiconductor kev lag luam

• CMP Polishing: Siv rau kev teeb meem ntawm silicon wafers thiab gallium arsenide (gaas) wafers, xav tau nano-qeb -alumina.

{{0 {}} kho qhov muag thiab tso saib kev lag luam

• Sapphire Polishing: lub xov tooj ntse smartphones npog thiab coj cov substtrates yuav tsum muaj kev dawb huv-purity -alumina (0}} 1-0.5 μm).

• Cov iav lens: txo cov roughness) (ra<1 nm).

3. ua hlau ua

• Daim iav Stainless iav Polishing: Roug Polishing (5 μm) + Zoo polishing (1 μm) kev sib xyaw ua ke {}}

{{04. ceramics thiab composite cov ntaub ntawv

• Hauv Ceramic Ceramt: Precision Polishing ntawm Alumina Ceramics .

Alumina polishing hmoovtau dhau los ua cov khoom siv irreplaable hauv thaj teb kev lag luam zoo ib yam li kev lag luam zoo nkauj thiab kev ua lag luam dav dav thiab cov txheej txheem ua kom zoo dua qub yuav dhau los ua cov tub ntxhais kawm
