Calcined Alumina
Calcined Alumina yog ib tug coj mus muag Alumina los yog Aluminium Oxide. Nws yog dawb hmoov. Ib tug ntawm cov koj cov yam ntxwv ntawm Calcined Alumina yog nws hardness uas yog 9 rau mohs scale. Muaj yog board muaj teb ntawm daim ntaub ntawv rau no hom ntawm alumina thiab tus xov tooj ntawm yus qib yog ua kom tau raws li ntau yam xav tau kev pab.
Qhia txog qib
1) Calcined Aluminium S-100 qib: Dawb granular free ntws hmoov kis tau los ntawm 150 m.
2) Calcined Aluminium S-300 qib: Dawb Superfine lub hmoov kis tab sis yog 45 micron.
3) Calcined Alumina SCM kawm qib: Nws yog thaum kawg av qib muaj nkaus ntawm Superfine lub kis los ntawm 45 micron.
4) Calcined Alumina S-300 PT: Nws yog finely av qib muaj nkaus ntawm Superfine lub nrog nto kho.
Siv
Siv raws li ib tug ntaub pua chaw pw khoom nyob rau hauv lub tshav kub kev kho mob tshwj xeeb hlau steels, Nws yog siv raws li ib tug fluxing nrab nyob rau hauv lub rooj sib tham tshwj xeeb steels li ib feem ntawm cov uas tsis muaj expansion iav. Nws yog siv raws li ib tug constituent tshwj xeeb Tuam Tshoj dazes & nws yog siv raws li ib tug raw khoom rau qhov siv thiab ua cov kev kho hniav porcelains. Nws yog siv rau refractory daim ntawv thov xws li hluav taws xob insulators. Nws yog siv raws li ib tug abrasive resistant. Nws yog siv glazing tej hub vuas.
Ordinary Calcined Alumina
High quality txhuas hydroxide li raw khoom, nws yog calcined los ntawm teb kiln thaum tsim nyog calcine kub. Nws muaj qhov zoo siab hloov dua siab tshiab npaum li cas, siv lead ua stability, siab txhua yam dag lub zog, ruaj khov shrinkage tus nqi, hnav kuj, corrosion kuj thiab kub kuj.
