Brown Aluminium Oxide

Brown Aluminium Oxide (Al₂O₃) tseem hu ua Brown Fused Alumina (BFA), muaj npe los ntawm nws cov xim xim av. Nws yog tsim los ntawm fusion ntawm high-zoo Calcined Bauxite nyob rau hauv ib tug hluav taws xob arc rauv ntawm kub kub ntau tshaj 2000 degree. Bauxite siv los ua BFA muaj siab Aluminium Oxide (Al2O3). Tom qab cov txheej txheem fusion, cov ntaub ntawv sib xyaw thiab fused rau hauv cov ntaub ntawv ua kua, ces txias thiab crushed (milled) rau hauv pob qhov ntau thiab tsawg. Cov pob loj me yog tom qab ntawd hauv cov qib finer lossis hmoov thiab ua kom zoo los ntawm cov khoom siv sieving rau hauv cov khoom sib txawv particle rau ntau daim ntawv thov.

Peb lub zog muaj zog compression siab, siab toughness, zoo heev self-sharpening, tsawg coefficient ntawm thermal linear expansion, crystallization zoo, thiab zoo heev hydrophilia thiab huv si. Nws yog cov khoom siv huv, muaj zog siab uas tiv taus oxidation thiab corrosion kuj, tswj cov tshuaj lom neeg ruaj khov, thiab tiv taus qhov kub thiab txias. Nws muaj ntau daim ntawv thov nyob rau hauv cov ntaub ntawv refractory.

Xim av fused alumina bauxite li raw khoom, thee, hlau, kub siab tshaj 2000 degrees hitches nyob rau hauv arc smelting, lub zeb sib tsoo yas, sib nqus sib cais rau hlau, tshuaj ntsuam yog muab faib ua ntau yam particle loj, ntom ntom ntom, siab hardness, particle tsim globular, siab consolidation yog tsim rau ua ceramic, resin abrasive thiab sib tsoo, polishing, sandblasting, casting, thiab lwm yam., kuj yuav siv tau rau manufacturing advanced refractories.

Vim nws lub zog siab thiab lwm yam khoom, nws yog siv los cam khwb cia hlau zawv zawg nozzle, smelting tsis tshua muaj hlau, tshwj xeeb alloys, ceramics, blast furnace hauv ob sab phlu (phab ntsa thiab yeeb nkab); Lub cev thiab cov khoom siv tshuaj, lub txim hluav taws xob, cua sov - oxidation - resistant txheej.

NY TWO refractory castables yog ua los ntawm refractory aggregate, refractory hmoov, binder, thiab lwm yam additives, thiab yuav siv tau ncaj qha los yog los ntawm kev ntxiv qhov tsim nyog cov dej los yog lwm yam kua. Thaum cam khwb cia los yog phom rau hauv qhov chaw, cov khoom castable hardens thiab kho kom tsim tau cov khoom ruaj khov thiab ruaj khov hauv ob sab phlu. Refractory castables tuaj yeem ntsia tau siv ntau txoj hauv kev nyob ntawm cov ntawv thov tshwj xeeb thiab cov khoom siv. Xws li casting, phom, troweling, thiab twj tso kua mis.

Raw Khoom: Tshawb nrhiav qhov chaw thiab muaj pes tsawg leeg ntawm Brown-Fused Alumina

Brown Fused Alumina (BFA) yog cov khoom ntom ntom thiab cov khoom siv tau los ntawm bauxite. Bauxite, thawj cov khoom siv raw, yog ib qho txhuas ore uas muaj feem ntau ntawm cov zaub mov gibbsite (Al (OH) 3), boehmite (-AlO (OH)), thiab diaspore (-AlO (OH)), tov nrog hlau oxides thiab Lwm yam impurities xws li silica thiab titania.

Cov txheej txheem pib nrog kev ua kom huv ntawm bauxite, qhov twg impurities raug tshem tawm los ntawm kev ntxuav thiab tshuaj ntsuam. Lub refined bauxite yog ces calcined ntawm kub kub los tsim alumina (Al2O3). Lub alumina yog tom qab fused hauv hluav taws xob arc rauv los tsim Brown Fused Alumina. Cov khoom kawg muaj txog 95% Al2O3, nrog me me ntawm hlau oxide (Fe2O3) thiab silica (SiO2).
