Waa maxay farqiga u dhexeeya leben corundum mullite iyo leben aluminium sare ah?

Farqiga ugu weyn ee u dhexeeya lebenka corundum mullite iyo lebenka aluminium sare waa wajiga crystal, iyo muuqaalka iyo midabka xoogaa kala duwan. Sababta ugu weyn waa saamiga alaabta ceeriin. Fadlan hoos ka eeg hordhaca oo faahfaahsan.

Leben mullite Corundum

Waxay leedahay awood heerkul sare oo wanaagsan, iska caabin heerkul sare ah, iska caabin shoog kulayl ah iyo iska caabin daxalka. Qalabka jirka iyo kiimikaad ee lebenka corundum mullite ee caadiga ah waa Al2O3> 85%, Fe2O30.45%, porosity muuqata 19%, heerkulka caadiga ah ee xoogga cadaadiska 55MPa, heerkulka jilcin ee ka sarreeya 1700 ℃, isbeddelka khadka kuleylka (1600 ℃, 3h) -0.1 %.

Leben alumina sare

Waxyaabaha ku jira oksaydhka aluminiumku waa 48% ilaa 85%, kaas oo loo qaybin karo gaar ahaan, hoose, sare, jaamacadeed, iwm. 2 ℃, isbeddelka fiilada kululaynta (30.45 ℃, 19h) -55%, caabbinta naxdinta kulaylka (1700 ℃ biyaha qaboojinta) in ka badan 1600 jeer. Alaabtu waxay isticmaashaa aluminium-alum clinker-sare oo ah alaabta ceeriin ee ugu muhiimsan, dhoobada jilicsan iyo qashinka qashinka iyo dareeraha warqadda sida wakiilka ku xiran, iyo dhoobada leh qaybo badan oo kala duwan ayaa lagu sameeyay qaabaynta cadaadiska sare, qalajinta iyo dabka heerkulka sare.
