Sharaxaad Gaaban

Aluminas falcelin ah ayaa si gaar ah loogu talagalay soo saarista refractories waxqabadka sare halkaas oo xirmo qayb qeexan, rheology iyo sifooyin meelaynta joogto ah muhiim u yihiin sida sifooyinka sare ee jirka ee alaabta kama dambaysta ah. Alumina-yada fal-celiska ah ayaa si buuxda hoos ugu dhiga ilaa kan ugu horreeya (hal) kiristaalo iyadoo loo marayo habab wax-ku-shiidid aad u hufan. Celceliska cabbirka walxaha, D50, ee aluminium-modal fal-celineed, sidaas darteed waxay ku dhowdahay dhexroorka hal kiristaalo. Isku darka aluminas falcelinta leh qaybaha kale ee matrixka, sida alumina alumina 20μm ama spinel 20μm, waxay u oggolaanaysaa xakamaynta qaybinta cabbirka qaybinta si loo gaaro rheology meelaynta la doonayo.

Tilmaamaha Alaabta

Aluminas fal-celin ah oo laga bilaabo-micron-hoosaad ilaa cabbirka walxaha 3 micron. Qaybinta cabbirka walxaha, oo u dhaxaysa mono-modal ilaa laba-modal iyo modal-badan, waxay u oggolaataa dabacsanaan buuxda xagga naqshadaynta qaabaynta oo waxay siisaa ku habboonaanta aluminas-ka-soo-baxa-dhaqdhaqaaqa leh ee isku-dhafan.

The alumina micro-budada reactive, sameeyey iyada oo loo marayo habka sintering gaar ah, habka shiidi iyo kala soocidda awoodda multistage, waxay leedahay daahirnimo sare, qaybinta qaybinta qayb wanaagsan iyo hawl sintering aad u fiican, kaas oo ku habboon codsiga in wax soo saarka ee wax soo saarka ee wax refrac-tory sare. , iyo alaabta ceramics elektarooniga ah .The reactive alfa alumina micropowerd si fiican loo xakameeyo karaa qaybinta size qayb ee kala duwan ee submicron, taasoo keentay in ay la hadhuudh xirxiro aad u fiican cufnaanta hantida rheological wanaagsan iyo workability deggan iyo sidoo kale sintering waxqabad wanaagsan, kaas oo ciyaaro gaar ah. doorka dib-u-celinta:
1. Adigoo wanaajinaya ururinta walxaha si loo yareeyo tirada biyaha lagu daro
2. Iska caabbinta xirashada iyo xoogga farsamada ayaa lagu wanaajiyaa iyada oo la samaynayo weji isku xidhka dhoobada adag;
3. Waxqabadka heerkulka sare ee alaabta ayaa lagu wanaajiyaa iyada oo lagu beddelayo budada ultra-fine oo leh dib-u-celin hoose.

Reacfive Alumina Ultrafine ee Dib-u-soo-celinta Waxqabadka Sare

Budada yaryar ee a-alumina ee fal-celiska ah waxaa loo isticmaali karaa kabka ladle, kabka BF, furayaasha nadiifinta, baloogyada fadhiga, kabka alumina is-socodka ah, iyo isku darka qoryaha sidoo kale, kuwaas oo la soo saaray iyada oo la tixraacayo heerarka Shirkadda Transnational. Budadani waxay leeyihiin wasakh hoose oo hoose, qaybinta cabbirka walxaha macquulka ah iyo falcelinta, waxay siinayaan qulqulka qulqulka wanaagsan, furfurnaan yar, waqti shaqo oo habboon, qaab dhismeed cufan iyo xoog aad u fiican, iyo
waxaa loo dhoofiyay Japan, USA, iyo Europe.

Aluminas fal-celin ah oo loogu talagalay Refractories Waxqabad Sare

The aluminas dhulka si buuxda u falcelis ah waxaa si gaar ah loogu talagalay soo saaridda ee refractories waxqabadka sare, halkaas oo xirxiro qayb qeexan, rheology iyo sifooyin meelaynta joogto ah yihiin sida muhiim u ah prop-erties jireed sare ee alaabta kama dambaysta ah.

Waxqabadka Alaabta
Qaybinta cabbirka walxaha ganaaxa ee aadka loo xakamaynayo ilaa kala duwanaanshaha mikroroon-hoosaadka iyo falcelinta falcelintooda aadka u wanaagsan waxay siinaysaa Aluminas-ka-soo-jiidashada hawlo gaar ah oo ku jira qaab-dhismeedyada refractory.

Kuwa ugu muhiimsan waa:
• Yaree isku darka biyaha isku-dhafan ee refractories adiga oo gacan ka geysanaya hagaajinta baakadaha walxaha.
• Kordhi caabbinta nabarka iyo xoogga farsamada iyadoo la samaynayo curaarta dhoobada ee xooggan.
• Kordhi wax qabadka makaanikada heerkulka sare iyadoo lagu bedelayo agabka kale ee aadka u fiican ee ka soo horjeeda hoose.
