Cov teb thov thiab qhov zoo ntawm cov xuab zeb corundum xim av
Xim av corundum xuab zeb, tseem hu ua xim av corundum lossisxim av fused corundum, yog ib hom khoom siv dag ua los ntawm bauxite zoo ua cov khoom siv tseem ceeb, smelted thiab txias ntawm qhov kub siab tshaj 2000 ℃ hauv lub cub hluav taws xob arc. Lub ntsiab tivthaiv yog txhuas oxide (Al₂O₃), thiab cov ntsiab lus feem ntau yog siab dua 95%. Vim nws qhov nyuaj siab, zoo toughness, muaj zog hnav tsis kam thiab zoo heev kub tsis kam, nws yog dav siv hauv ntau qhov chaw lag luam. Nrog rau kev txhim kho tas mus li ntawm cov khoom siv ua tiav qhov yuav tsum tau ua, daim ntawv thov ntawm xim av corundum xuab zeb hauv abrasives, refractory cov ntaub ntawv, kev kho saum npoo, casting thiab cov khoom siv ua haujlwm tau dhau los ua qhov tseem ceeb.
1. Daim ntawv thov dav dav hauv cov khoom siv abrasives
Cov khoom siv sib tsoo yog ib qho ntawm cov teb siv ib txwm muaj thiab tseem ceeb tshaj plaws ntawm cov xim av corundum. Vim nws qhov Mohs hardness txog li 9.0, thib ob tsuas yog pob zeb diamond thiab silicon carbide, xim av corundum yog siv dav hauv kev tsim ntau yam khoom sib tsoo, xws li cov log sib tsoo, daim ntaub emery, ntawv xuab zeb, pob zeb roj thiab cov taub hau sib tsoo. Txawm hais tias hauv kev ua hlau, iav polishing lossis ceramic sib tsoo, xim av corundum tuaj yeem muab lub zog txiav zoo thiab tiv taus hnav zoo. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej kev lag luam uas xav tau kev txiav muaj zog thiab ruaj khov cov duab khaws cia, xim av corundum abrasives ua tau zoo tshwj xeeb.
2. Ua ib qho khoom siv tseem ceeb rau cov ntaub ntawv refractory
Xim av corundum muaj qhov kub refractory siab heev thiab zoo heev thermal stability, yog li nws yog dav siv los tsim ntau yam khoom refractory ua tau zoo.cov cub tawg kub kubxws li metallurgy, hlau, cement, thiab iav, xim av corundum tuaj yeem siv los tsim cov cib refractory zoo, castables, plastics, ramming cov ntaub ntawv thiab lwm yam khoom refractory, tshwj xeeb tshaj yog rau cov khoom uas muaj kev kub ntxhov hnyav thiab kev poob siab thermal ntau zaus. Piv nrog cov ntaub ntawv txhuas siab ib txwm muaj, cov ntaub ntawv refractory xim av corundum muaj kev tiv thaiv slag thiab spalling zoo dua, ua kom lub neej ua haujlwm ntawm cov khoom siv ntev dua thiab txo cov nqi txij nkawm.
3. Daim ntawv thov hauvkev xuab zebthiab kev kho qhov chaw
Cov xuab zeb corundum xim av yog siv dav hauv kev xuab zeb ntawm cov hlau vim nws qhov loj me sib xws, qhov nyuaj siab thiab qhov hnyav tshwj xeeb. Thaum lub sijhawm xuab zeb, cov xim av corundum tuaj yeem tshem tawm cov xeb, nplai, txheej xim qub, thiab lwm yam ntawm qhov chaw ua haujlwm, thiab txhim kho qhov huv ntawm qhov chaw thiab kev nplaum. Tib lub sijhawm, vim nws qhov kev ua kom ntse zoo thiab tsis yooj yim rau passivate, nws tuaj yeem rov ua dua tshiab thiab siv ntau zaus, txo cov nqi khoom siv. Tsis tas li ntawd, cov xim av corundum kuj qhia txog cov teebmeem tshwj xeeb hauv kev kho mob matte thiab kev ua cov qauv ntawm cov ntaub ntawv xws li hlau tsis xeb, txhuas profiles, iav, thiab ceramics.
4. Daim ntawv thov hauv kev ua kom raug
Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho tas mus li ntawm kev siv tshuab precision casting, cov kev cai siab dua tau muab tso rau pem hauv ntej rau kev huv thiab thermal stability ntawm cov ntaub ntawv casting.Xim av corundum tau dhau los ua cov khoom siv plhaub zoo tagnrho rau kev ua cov khoom siv precision xws li cov hlau kub siab, hlau tsis xeb, thiab cov hlau carbon vim nws cov tshuaj lom neeg ruaj khov, kev ua kom sov zoo, thiab cov coefficient nthuav dav thermal qis. Xim av corundum casting xuab zeb tuaj yeem txhim kho qhov zoo ntawm cov castings thiab txo cov teeb meem casting. Nws yog siv dav hauv cov teb tsim khoom siab xws li aviation, tsheb, thiab lub zog.
5. Siv ntev dua li kev ua haujlwm puv ntoob
Xim av corundum kuj tseem siv tau ua cov khoom sib xyaw ua ke hauv cov khoom xws li cov plag tsev tiv thaiv kev plam, cov kev taug kev uas tsis yooj yim hnav, cov tshuaj pleev xim resin, thiab cov ntaub ntawv tsim kho siab. Nws qhov nyuaj thiab kev tiv thaiv compressive zoo heev pab txhim kho kev tiv thaiv kev hnav thiab kev pabcuam lub neej ntawm cov ntaub ntawv sib xyaw. Hauv cov teb ntawm cov khoom siv hluav taws xob, ceramics, roj hmab, thiab lwm yam, xim av corundum micropowder kuj tseem siv tau ua cov khoom sau kom txhim kho kev tiv thaiv cua sov, thermal conductivity, thiab lub zog ntawm cov khoom.
Xaus lus
Xuab zeb corundum xim av ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub nrog nws cov khoom zoo heev thiab kev ruaj khov tshuaj lom neeg. Nrog kev txhim kho ntawm cov khoom siv thev naus laus zis thiab kev xav tau kev ua haujlwm hauv kev lag luam, kev cia siab ntawm kev ua lag luam ntawm xuab zeb corundum xim av yuav dav dua thiab tseem yuav coj cov kev daws teeb meem zoo dua thiab zoo rau ib puag ncig rau ntau yam kev lag luam.
