Xidho dhoobada Alumina ee adkaysta
Macluumaadka Alaabta
Alumina ceramic, oo sidoo kale loo yaqaan aluminium oxide ama Al2O3, waa dhoobada oksaydhka ah ee si weyn looga isticmaalo warshadaha.Qalabka dhoobada alumina waxaa lagu yaqaanaa adkeysigooda aadka u sarreeya iyo kuleylka kuleylka sarreeya.Astaamaha ceramics alumina waxay ka dhigaan mid ka mid ah dhoobada aadka loo isticmaalo ee qaab dhismeedka, xirashada iyo deegaanka daxalka.
Aluminium oxide waxaa lagu gartaa adkeysi aad u sarreeya, iska caabin daxalka, xasilloonida kulaylka, sifooyinka dielectric ee wanaagsan (ka beddelka DC ilaa GHz), taangiga luminta hooseeya iyo qallafsanaanta.
Alumina ceramics waxaa loo qaybiyaa iyadoo loo eegayo nuxurka Al2O3 ee maaddada.Kuwa caadiga ah waa: 75%, 95%, 99%, 99.5%, 99.7% alumina ceramics, iwm. Caadi ahaan, waxaan dooranaa nadiifnimada ceramics alumina iyadoo lagu saleynayo shuruudaha waxqabadka ee alaabta aan samayno.
Qaybaha Alaabta
1. Kubbada Alumina
Kubadaha aluminiumku waa unugyo aluminium oxide ah oo aan wareegsanayn kuwaas oo si weyn loogu isticmaalo warshadaha petrochemical, beeraha iyo dahaarka.
Kubadaha alumina waxay si toos ah u geli karaan falcelinta, si weyn u yaraynaysaa saameynta kicinta, taas oo kordhinaysa nolosha adeegga kicinta.Intaa waxaa dheer, kubbadaha alumina ayaa sidoo kale loo isticmaali karaa in lagu sameeyo dahaarka ilaalinta dusha sare.Ka dib marka lagu buufiyo birta, balaastiigga iyo meelaha kale, waxay hagaajin kartaa adkaanta dusha sare, caabbinta daxalka, xirashada caabbinta iyo dib u dhaca ololka.
Warshadaha elektiroonigga ah, kubbadaha aluminium ee wareegsan ayaa muhiimad weyn u leh goobta baakadaha elektiroonigga ah sababtoo ah sifooyinkooda korantada, kulaylka iyo farsamada wanaagsan.
Baaxadda cabbirka walxaha: 0.3-0.4, 0.4-0.6, 0.6-0.8, 0.8-1.0, 1.0-1.2, 1.2-1.4, 1.4-1.6, 1.8-2.0, 2.0-2.2, 2.2-2.4, 0.0.2 3.2, 3.2-3.5, 4.5-5.0, 5.0-5.5, 6.0-6.5, 6.5-7.0, 8, 10, 12, 15, 20.
Kubadaha shiida ee alumina
Kubadaha wax lagu shiido alumina waa qaybo wareegsan oo ka samaysan aluminium saafi ah oo sarreeya waxaana caadi ahaan loo isticmaalaa sida abrasives ama warbaahinta shiida.Sababtoo ah adkeysigeeda sare iyo caabbinta xirashada wanaagsan, waxaa sidoo kale si weyn loogu isticmaalaa warshadaha leh shuruudaha sare ee shiida iyo xirashada caabbinta.
