Cov tswv yim yooj yim ntawm lub teeb corundum mullite cib
Corundum thiab mullite yog cov khoom tseem ceeb uas ua los ntawm teeb pom kev zoo, kev txuag tshav kub, kev txuag hluav taws xob thaum tshav kub kub
Lub ntsiab Cheebtsam ntawm lub teeb corundum mullite cib:
Al2O3 cov ntsiab lus ntawm lub teeb corundum mullite cib yog: 1500 hom: ≥ 70%, 1550 hom: ≥ 75%, 1600 hom: ≥ 80%, thiab ≥ 85%, cov ntsiab lus SiO2 yog: 1500 hom ≤ 28%, 1550 hom ≤ 23%, 1600 hom ≤ 18%, thiab ≤ 13%, Cov ntsiab lus Fe2O3 tsis ntau dua 0.5% - 0.8%, qhov ntim ntau yog 1.3-1.7g / cm3, thauj (0.2MPa) qhov kub tsis txias tsis tsawg dua 1500 ℃ - 1600 ℃, kev ua cua sov yog 0.48-0.72w ／ (m • K).
Cov txheej txheem tsim khoom thiab cov yam ntxwv ntawm lub teeb corundum mullite cib:
Lub teeb corundum mullite cib yog ua los ntawm fused dawb corundum thiab fused mullite. Qhov poob ntawm cov paib tus neeg sawv cev yog sib xyaw thiab zoo li tus duab hauv qhov ntsuas thiab tua ntawm qhov kub. Nws muaj cov yam ntxwv ntawm qhov kub tsis kam tiv thaiv, tsis tshua muaj cua sov (kev ua tau zoo ntawm kev tiv thaiv tshav kub, daim nyias nyias phab ntsa, tus nqi qis), siab zog, siab poob siab thermal stability, thiab lwm yam.
Daim ntawv thov ntu ntawm lub teeb corundum mullite cib:
Cov khoom muaj qhov zoo ntawm lub teeb yuag, siab kub tsis kam, hloov me me ntawm kev thim rov qab, zoo thermal poob siab tsis kam, kev siv tus nqi kiln thiab lub zog txuag hluav taws. Cov khoom siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, iav, ceramics, refractories thiab lwm yam kev lag luam ntawm qhov kub siab kub, zoo txais los ntawm cov neeg siv.
