Dawb Aluminium oxide yog hom corundum heev ntawm cov khoom abrasidity. Dawb fated alumina abrasives tau siv dav hauv ntau daim teb. Nws lub luag haujlwm hauv kev lag luam nrhiav tau kuj tseem yog kuv li.
Yog li casDawb ox oxideTxhim kho qhov chaw zoo ntawm cov cuab yeej ua?
Nyob rau hauv xyoo tsis ntev los no, kev siv zirconium silicate raws li cov plhaub cov khoom hauv cov teb chaws noo thiab Asmeskas tau txhim kho lub plhaub kev ua tau zoo thiab ua kom zoo dua ntawm qhov chaw zoo ntawm cov cuab yeej. Los ntawm kev xyaum ntawm cov txheej txheem kev txhim kho hniav, nws yog qhov pom tseeb tias kev ua tau zoo thiab muaj kev cuam tshuam ntawm zircon cov ntaub ntawv sib txawv heev nyob ntawm lawv cov qib, keeb kwm ntawm ORE thiab tus nqi.
Cov nyhuv ntawm cov xim dawb txhuas yuav cuam tshuam nws cov nyhuv. Yuav ua li cas txiav txim siab qhov zoo ntawm cov neeg nplua dawb?
Dawb Aluminium oxide muaj cov impurities thaum lub txheej txheem ntau lawm. Lub ntsiab impurities yog siio2, FE2O3, Tio2Cov. Cov impurities tsawg dua, qhov siab dua qhov zoo ntawm cov alumina dawb. Kev txiav txim rau cov ntsiab lus ntawm cov ntsiab lus hauv cov xim dawb dawb oxide tau dhau los ua ib txoj kev los txiav txim qhov zoo ntawm alumina. Tsis tas li ntawd, cov ntsiab lus ntawm Al2O3Hauv Alumina Dawb kuj ncaj qha qhia qhov zoo ntawm dawb corundum.
Cov xim dawb oxide kuj tseem siv tau ua cov khoom siv refactory.
Yog tias nws muaj impurities, nws yuav cuam tshuam nws txoj kev ua tau zoo. Qee qhov kev tsis txaus ntseeg hauv cov ntaub ntawv refractory yog fusTractory, thiab qee tus muaj lub ntsiab lus zoo heev, tab sis thaum lawv ua rau cov tshuaj tseem ceeb, lawv tuaj yeem tsim cov tshuaj fusible. Yog li ntawd, lub xub ntiag ntawm kev tsis txaus siab feem ntau muaj cov nyhuv muaj zog rau ntawm lub ntsiab tivthaiv. Txawm hais tias fluxing nyhuv ntawm cov xim dawb txhuas pab cov theem ua kua Sintering ntawm cov khoom siv, nws muaj kev phom sij rau cov khoom siv tiv thaiv kub.
