Dab tsi yog siab alumina sib tsoo pob?

Cov Khoom Loj Sib TsooYog hom kev sib tsoo sib tsoo ceramic ua los ntawm high-purity alumina (al2o3) raws li cov khoom siv tseem ceeb. Lawv tau dav siv nyob rau hauv cov hmoov sib tsoo cov txheej txheem hauv kev tsuas, cov ntaub ntawv tsim tsev, tshuaj, khoom siv hluav taws xob thiab lwm yam khoom siv hluav taws xob thiab lwm yam khoom siv hluav taws xob thiab lwm yam khoom siv hluav taws xob thiab lwm yam khoom lag luam. Lawv muaj cov yam ntxwv zoo xws li hardness siab, siab coj tsis kam, corrosion tsis kam, thiab kub tsis kam. Lawv tuaj yeem txhim kho kev sib tsoo thiab ua kom muaj kuab paug. Lawv yog cov neeg tseem ceeb hauv kev lag luam hauv kev lag luam niaj hnub thiab kev ua khoom siv.

Cov yam ntxwv ntawm Cov Khoom Loj-Aluminium Sib Tsoo:

(1) hardness siab thiab hnav tsis kam

• Lub mohs hardness ncav cuag 8 ~ 9 (ze rau corundum), thiab cov coj tsis kam txo tau cov hnav thaum lub neej sib tsoo.

(2) muaj zog corrosion tsis kam

• Nws tau ua kom zoo heev rau cov kua qaub, alkalis, cov kuab tshuaj organic, thiab yog qhov haum rau cov tshuaj lom neeg muaj kev lag luam thiab metallurgy.

(3) Cov Kub Ntsuas Kub Kuj

• Nws tuaj yeem ua haujlwm stably ntawm 1400 degree ~ 1600 degree, haum rau kev sib tsoo siab lossis ib puag ncig ib puag ncig.

(4) tsis muaj kuab paug

• Yuav luag tsis muaj impurities tau qhia thaum cov txheej txheem sib tsoo los xyuas cov khoom siv hluav taws xob, uas yog tsim nyog rau kev npaj ntawm cov ntaub ntawv hluav taws xob, tshuaj, thiab cov hmoov noj muaj txiaj ntsig.

(5) txuag hluav taws xob thiab kev txo qis

• Lub qhov ceev yog qhov nruab nrab (3.2 ~ 3.9 g \/ cm³), kev sib tsoo efficievicy yog siab, thiab lub zog siv cov khoom siv tuaj yeem txo.

Kev sib piv ntawm siab Alumina sib tsoo cov pob thiab lwm yam kev sib tsoo:

Lub zog loj sib tsoo pob tau ua si lub luag haujlwm muaj zog hauv ntau yam kev lag luam vim lawv cov khoom siv lub cev thiab tshuaj lom neeg, thiab tuaj yeem siv rau yuav luag txhua tus neeg muaj hmoov sib tsoo. Piv txwv li, tsuas thiab metallurgy: ultra-nplua sib tsoo ntawm cov miner hlau xws li kub, hlau, thiab tooj; Cov ntaub ntawv tsim tsev thiab ceramics: npaj cov hmoov nplej xws li MAAs, Quaramic xuab zeb, ceramic ci, thiab kaolin; Kev Lag Luam Tshuaj: Sib tsoo ntawm cov khoom siv raw tshuaj raw xws li catalysts, pigments, pleev xim, thiab tshuaj tua kab; Lub Zog Tshiab: Ultra-Hniav Sib Tsoo ntawm cov khoom muaj txiaj ntsig thiab tsis zoo ntawm cov roj ntsha lithium (xws li Iron piv txwv), thiab cov khoom siv tsis tshua muaj roj av) Cov ntaub ntawv hauv hluav taws xob: kev ua qias tuaj sib tsoo ntawm cov khoom siv hluav taws xob, cov ntaub ntawv sib nqus, thiab cov khoom siv semiconductor; Tshuaj thiab Khoom Noj: High-purity sib tsoo ntawm cov tshuaj lom neeg thiab cov khoom noj ntxiv khoom noj ntxiv, thiab lwm yam.

Cov Khoom Loj Sib Tsootau dhau los ua qhov kev xaiv tseem ceeb hauv cov hmoov kev lag luam niaj hnub vim lawv cov kev ua tau zoo heev, corrosion tsis kam thiab kub tsis kam. Seb nws yog qhov tsuas, tshuaj lom neeg, lub zog tshiab lossis cov ntaub ntawv hluav taws xob kev lag luam, high-txhuas sib tsoo cov khoom tuaj yeem muab cov kev daws teeb meem thiab tsis muaj kuab paug. Xaiv cov ntsiab lus alumina sab xis thiab cov lus qhia tshwj xeeb tuaj yeem txhim kho kev ua haujlwm zoo thiab txo cov nqi tag nrho.
