Alumina sib tsoo pob tau siv dav hauv kev lag luam ceramic, yog li dab tsi ua rau lawv lees paub los ntawm kev lag luam ceramic? Vim lawv cov khoom siv kho tshuab zoo heev, hnav tsis kam, corrosion kuj thiab lwm yam ntxwv. Lawv tau siv dav hauv kev sib tsoo thiab sib tsoo ntawm ceramics, xws li glaze thiab lub cev npaj, pobzeb tsim, refractory manufacturing, thiab lwm yam.
Alumina npas yog ua los ntawm high-density alumina, uas muaj siab hardness thiab zoo heev mechanical zog. Cov khoom npaj los ntawm txoj kev sintering tuaj yeem tsim cov khoom me me nrog cov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
Alumina sib tsoo pob muaj ntau qhov zoo rau kev siv hauv kev lag luam ceramic. Ua ntej, alumina npas muaj qhov zoo heev corrosion kuj thiab tshwj xeeb tshaj yog haum rau acidic thiab alkaline ib puag ncig. Cov yam ntxwv no tseem ceeb heev rau kev lag luam ceramic, raws li ntau cov txheej txheem yuav tsum tau ua nyob rau hauv acidic los yog alkaline ib puag ncig.
Qhov thib ob, cov txheej txheem microstructure ntawm alumina ua kom ntseeg tau qhov sib xws ntawm nws cov yam ntxwv sib tsoo, kom cov khoom loj me me ntawm cov khoom siv ceramics sib xws.
Tsis tas li ntawd, vim nws cov hardness siab thiab qis hnav tus nqi, nws muaj kev sib tsoo siab, uas txo tus nqi ntawm kev hloov cov abrasives.
Alumina sib tsoo pob yog ib qho tseem ceeb ntawm cov khoom siv ceramic nrog cov khoom siv zoo heev, hnav thiab corrosion kuj, ua rau lawv zoo heev rau kev sib tsoo. Cov khoom lag luam no muaj kev sib tsoo siab ua haujlwm thiab cov khoom sib txawv me me, thiab tuaj yeem muab ntau yam kev qhia tshwj xeeb raws li kev thov tshwj xeeb.
