Fused Brown Aluminium Oxide Technical Data

Fused Brown Aluminium Oxide Technical Data: Yam Koj Yuav Tsum Paub

Fused xim av aluminium oxide yog ib qho ntawm cov khoom siv dav siv niaj hnub no. Nws yog feem ntau siv rau hauv kev tsim thiab ua tiav ntawm cov hlau qhov chaw, xws li bearings, gears, thiab lwm yam high-precision Cheebtsam. Tab sis dab tsi yog nws ua los ntawm, thiab dab tsi yog nws cov specifications?

Kev sau thiab kev tsim khoom

Fused xim av aluminium oxide yog tsim los ntawm bauxite ore, uas yog thawj zaug crushed, ces purified thiab refined kom tshem tawm tej impurities. Lub resulting alumina yog ces yaj nyob rau hauv lub cub tawg ntawm tshaj 2000 degree elsius, qhov twg nws yog tov nrog hlau oxide thiab silica. Cov sib tov yog ces txias sai heev, uas ua rau nws solidify thiab tsim xim av aluminium oxide crystals.

Lub cev muaj zog

Fused xim av aluminium oxide muaj qhov ntsuas Mohs hardness ntawm 9, uas ua rau nws yog ib qho nyuaj tshaj plaws rau txiv neej. Nws kuj yog tuab heev, nrog lub ntiajteb txawj nqus ntawm 3.97 - 4.10 g / cm³. Nws cov ntsiab lus melting siab tshaj 2000 degree elsius thiab nws cov thermal conductivity zoo ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv kev siv kub.

Chemical Properties

Fused xim av aluminium oxideyog chemically inert, uas txhais tau hais tias nws tsis hnov ​​​​mob nrog lwm yam tshuaj. Nws kuj tseem tiv taus corrosion, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv nyob rau hauv ib puag ncig hnyav. Nws cov tshuaj ruaj khov thiab insolubility hauv dej ua rau nws yog ib qho khoom siv zoo heev rau kev siv hauv kev lag luam uas xav tau cov khoom zoo abrasives.

Daim ntawv thov

Fused xim av aluminium oxide feem ntau yog siv rau hauv kev tsim thiab ua tiav ntawm cov hlau. Nws cov hardness siab thiab ntom ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev sib tsoo, polishing, thiab ua tiav daim ntawv thov. Nws kuj tseem siv rau hauv kev tsim cov ntawv xuab zeb, sib tsoo lub log, thiab lwm yam khoom siv abrasive.

Lwm daim ntawv thov rau xim av fused aluminium oxide muaj xws li:

Txheej thiab kev npaj nto: Cov khoom siv yog siv los npaj cov chaw rau cov txheej txheem, nrog rau kev tsim cov txheej tiv thaiv plam.

Cov iav ntau lawm: Nws yog siv los kho cov iav thiab ua kom nws tsis kam ua kom tawg, nrog rau tshem tawm cov impurities ntawm iav.

Ceramic ntau lawm: Brown fused aluminium oxide yog siv los tsim cov ceramics nrog lub zog siab thiab ua haujlwm tsis zoo.

Refractory ntau lawm: Cov khoom siv yog siv los tsim cov khoom kub kub refractory uas yog siv rau hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam kev siv kub.

Environmental Impact

Fused xim av aluminium oxideyog ib tug natural resources uas yog mined thiab ua nyob rau hauv ntau qhov chaw nyob ib ncig ntawm lub ntiaj teb no. Cov txheej txheem ntau lawm tuaj yeem ua rau lub zog siv zog thiab tuaj yeem ua rau tso tawm cov pa hauv tsev cog khoom. Txawm li cas los xij, kev ntsuas tuaj yeem raug coj los txo qhov cuam tshuam ib puag ncig ntawm cov txheej txheem tsim khoom, xws li siv cov khoom siv hluav taws xob tauj dua tshiab thiab siv cov phiaj xwm rov ua dua tshiab.

Xaus

Fused xim av aluminium oxide yog ntau yam thiab dav siv cov khoom siv abrasive uas muaj ntau yam kev siv hauv kev tsim thiab ua tiav ntawm cov hlau. Nws cov hardness siab, ceev, thiab tshuaj stability ua rau nws ib tug zoo tagnrho cov ntaub ntawv rau siv nyob rau hauv ib tug ntau yam ntawm industrial daim ntaub ntawv. Thaum nws cov txheej txheem tsim khoom tuaj yeem muaj kev cuam tshuam ib puag ncig, cov kauj ruam tuaj yeem ua kom txo qis cov kev cuam tshuam no thiab xyuas kom muaj kev siv cov peev txheej muaj txiaj ntsig zoo.
