1. Kev xaiv thiab pretreatment ntawm bauxite: xaiv high-qib bauxite rau crushing, sib tsoo thiab lwm yam pretreatment.

2. Synthesis ntawm alumina: Cov tshuaj tiv thaiv ntawm bauxite nrog alkaline tov los ua ke alumina hydroxide.

3. Particle loj tswj ntawm txhuas hydroxide: Los ntawm kev tswj cov synthesis tej yam kev mob, aluminium hydroxide hais nrog txawv particle loj yog tau.

4. Kev ziab ntawm aluminium hydroxide: aluminium hydroxide yog qhuav kom tshem tawm cov dej noo.

5. Kev tua hluav taws ntawm alumina pob: cov pob aluminium hydroxide qhuav yog sintered ntawm qhov kub thiab txias kom tau txais cov khoom alumina.

6. Particle loj tswj ntawm alumina npas: Los ntawm kev sib tsoo thiab kev tshuaj ntsuam, alumina pob ntawm qhov sib txawv particle loj tau txais.

Cov yam ntxwv ua haujlwm

Spherical alumina muaj cov yam ntxwv hauv qab no:

1. Lub zog siab: spherical alumina muaj lub zog tensile siab thiab lub zog tawm los, thiab tuaj yeem tiv taus cov khoom loj.

2. High hnav tsis kam: spherical alumina muaj kev hnav zoo heev, uas tuaj yeem ua kom lub neej ntev ntawm qhov chaw.

3. Tsawg thermal conductivity: Lub thermal conductivity ntawm spherical alumina yog qhov tsawg, uas tuaj yeem txo qhov ceev ntawm kev hloov hluav taws xob, thiab tsim nyog rau lub sijhawm uas yuav tsum tau khaws cov cua sov.

Daim ntawv thov teb

Spherical alumina muaj ntau yam kev siv, suav nrog:

1. Aerospace: Spherical alumina tuaj yeem siv los tsim cov khoom siv dav hlau, aviation bearings, thiab lwm yam.

4. Kev tsim kho kev lag luam: spherical alumina tuaj yeem siv los tsim cov khoom siv hauv tsev, sib tsoo lub log, thiab lwm yam.

Kev txhim kho yav tom ntej

Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev lag luam ntawm cov alumina kheej kheej yuav txuas ntxiv.Nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm spherical alumina feem ntau yuav tsom rau cov hauv qab no:

1. Kev kho kom zoo: Los ntawm kev txhim kho cov txheej txheem ntau lawm thiab thev naus laus zis, kev tsim cov khoom me me me me, siab dua purity kheej kheej alumina kom tau raws li cov kev xav tau ntawm high-end teb.

2. Functionalization: Los ntawm kev ntxiv lwm cov ntsiab lus los yog siv cov cuab yeej tshwj xeeb ntawm kev kho deg, spherical alumina yog endowed nrog ntau lub zog, xws li conduction thiab magnetism.

3. Kev tiv thaiv ib puag ncig: Kev siv cov txheej txheem ntau lawm ib puag ncig thiab thev naus laus zis los txo cov nqi tsim khoom ntawm spherical alumina thiab ib puag ncig muaj kuab lom.

Nyob rau hauv luv luv, spherical alumina, raws li ib tug tshiab cov ntaub ntawv, muaj ib tug ntau yam ntawm daim ntawv thov prospects thiab lub tswv yim tseem ceeb qhov tseem ceeb.Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev ua haujlwm thiab kev siv thaj chaw ntawm spherical alumina yuav txuas ntxiv nthuav dav, thiab ua kom muaj txiaj ntsig tseem ceeb rau kev loj hlob ntawm noob neej.
