Sharaxaad Gaaban

Tabular Alumina waa walxo saafi ah oo lagu miiray heerkul sare oo aan lahayn MgO iyo B2O3 lagu daro, qaabdhismeedkiisu waa laba qaab-dhismeedka polycrystalline oo si fiican u koray oo koray α - Al2O3 crystals.Tabular Alumina waxay leedahay daloolo yar yar oo xiran oo ku jira crystal individval , Al2O3 waxay ka badan tahay 99% .Sidaas darteed waxay leedahay xasillooni mugga wanaagsan iyo caabbinta shoogga kuleylka , nadiifnimada sare iyo dib-u-soo-celinta , awoodda farsamada ee aad u fiican , caabbinta abrasion ka dhanka ah slag iyo walxaha kale.

Tabular & Isku-darka kale

Isku-darku waa laf-dhabarta habaynta dib-u-soo-celinta waxayna bixiyaan xasilloonida cabbirka alaabada dib-u-celinta.Jajabyada qallafsan waxay ku daraan shoogga kulaylka iyo iska caabinta daxalka iyo ganaaxyada wadarta guud waxay hagaajiyaan qaybinta cabbirka walxaha waxayna kordhiyaan refractoriness ee alaabta.

Tayada joogtada ah ee alumina Tabular waa natiijada habka sinter-ka si fiican loo xakameeyo oo leh heerkulka dabka ee ka sarreeya 1800 ° C. Isticmaalka foornooyinka heerkulka sare leh ee tiknoolajiyada casriga ah waxay oggolaataa cufnaanta alaabta ceeriin ee la doortay iyada oo aan la isticmaalin qalabka wax-soo-saarka kaas oo lahaan lahaa si xun u saameeya sifooyinka heerkulka sare ee refractories.

Natiijadu tahay habka sinter-ka, isku-darka isku-darka ah waxay soo bandhigaan isku mid ah macdanta iyo kiimikada dhammaan jajabyada.Ka soo horjeeda alaabooyinka isku dhafan ee wasakhdu ku ururto ganaaxyada, isticmaalka isku-darka isku-darka ah ee qaabaynta diidmada waxay dammaanad qaadaysaa dabeecad xasilloon oo la isku halayn karo.

Junsheng waxay bixisaa qiyaaso kala duwan oo isku geyn ah laga bilaabo jajabyo aad u qallafsan ilaa cabbirro dhul-gaaban oo <45 μm iyo <20 μm.Burburinta iyo shiididda waxaa raacda tillaabooyinka birta-dhigista degdega ah taas oo keenta in birta bilaashka ah ay aad u yar tahay gudaha jajabyada kala duwan.

Codsiga Aluminiinka Tabular

Alumina Tabular waa sheyga doorashada ee dib-u-celinta waxqabadka sare ee aan qaabaysanayn ee loo isticmaalo warshado kala duwan oo ay ka mid yihiin birta , foornada , sibidhka , dhalooyinka , kiimikaad , dhoobada , iyo gubida qashinka .Codsiyada kale ee caadiga ah ee aan leexleexeynin waxaa ka mid ah isticmaalka alaabta guriga iyo sifeynta birta.
