Tuubooyinka dhoobada iyo qaybaha gaarka ah

Sharaxaad Gaaban:

Xidho dhoobada adkaysiga u leh oo inta badan ka kooban ugu yaraan 90% Al2O3 ayaa ah kuwa ugu isticmaalka badan aduunka maanta.

Alaabadayada waxaa laga sameeyaa budada aluminiumka ah ee si adag loo doortay oo leh cabbirro isku mid ah iyo content CaO hooseeya. Xiro dhoobada adkaysi u leh ayaa lagu samayn karaa iyada oo loo marayo saxaafadda qalalan ee caadiga ah ama habka cadaadiska isostatic ka dibna iyaga oo ku dhejinaya heerkulka sare ee foornada.Waxay yihiin maaddooyin dahaarka loo jecel yahay oo loogu talagalay qalabka xirashada sare sababtoo ah cabbirka saxda ah, cufnaanta sare, content alumina sare, flatness wanaagsan iyo tayada xasilloon.

Tusaalooyinka Isticmaalka

Xusuusin: Waxaan samayn karnaa tile alumina xirashada sida waafaqsan shuruudahaaga.

Astaamaha

Adag sare

Adkeydka Rockwell ee ceramics-ka sare ee alumina waa ilaa HRA80-90 kaas oo ah kan labaad ee kaliya dheeman oo aad uga badan birta aan xirneyn

Iska caabbinta xirashada heer sare ah

Iska caabbinta xirashada ee ceramics sare ee alumina waa 266 jeer oo ka mid ah birta manganese iyo 171.5 jeer oo ka mid ah birta birta ah ee chromium. Sida laga soo xigtay baaritaankeena & dabagalka macaamiisha, nolosha adeegga qalabka ayaa lagu dheerayn karaa waqtiyo 10 oo isku mid ah. xaaladaha shaqada.

Iska caabin daxalka

dhoobada alumina sare waa oksaydhyo inorganic leh qaab-dhismeedka kelli aad u deggan oo aan lahayn daxalka electrochemical, sidaas darteed waxay iska caabin karaan nabaad guurka ee acid, alkali, milix xalalka iyo organic Solvents.

Heerarka kuleyliyaha

Heerkulka shaqada ee dhoobada aluminium sare waxay noqon kartaa ilaa 1400 ℃.

Is-jiid wanaagsan

Ceramics-ka sare ee alumina waxay leeyihiin sifooyinka is-dheellitirka iyo is-dheellitirnaanta, qallafsanaantu waa 1/6 oo keliya tan tuubooyinka birta sidaas darteed qulqulka qulqulka ayaa ka yar.

Miisaan fudud

Cufnaanta ceramics-ka sare ee alumina waxay ku saabsan tahay 3.6g/cm3, taas oo ah kala badh ka mid ah birta, sidaas darteed way fududahay dhismaha iyo rakibidda

Xiro xalalka aanu bixino

Tani waa nidaam adag. Injineeradayadu waxay fahmaan dhibaatooyinka xidhashada oo ay sheegaan

xalal aad ku buuxin karto jawiga shaqada.Guryaha alaabta, dulqaadka, fidsanaanta, hababka lifaaqa, iyo kharashyada agabka ayaa dhamaantood lagu tixgaliyaa xidhashada
