Leben Mullite ah iyo leben Sillimanite ah
Macluumaadka Badeecada
Leben Mulite ahWaa aluminiin sare oo iska caabiya oo leh mullite oo ah wejiga ugu weyn ee kiristaalka. Guud ahaan, maaddada alumina waxay u dhaxaysaa 65% iyo 75%. Marka laga soo tago mullite, macdanta leh alumina hoose waxay sidoo kale ka kooban tahay xaddi yar oo ah wejiga vitreous iyo cristobalite. Waxyaabaha alumina ee sare waxay sidoo kale ka kooban tahay xaddi yar oo corundum ah. Waxaa inta badan loo isticmaalaa foornada kulul ee qaraxda, jirka foornada qaraxa iyo hoose, dib-u-soo-saareyaasha foornada galaaska, foornada dhoobada, dahaarka geeska dhintay ee nidaamka dillaaca batroolka, iwm.
Kala-soocidda:Saddex Mullite Hoose/Sintered Mullite/Fused Mullite/Sillimanite Mullite
Lebennada Sillimanitewaa lebenno iska caabiya oo leh astaamo wanaagsan oo laga sameeyay macdanta sillimanite iyadoo la adeegsanayo sintering heerkul sare ama slurry casting. Sillimanite waxaa loo beddelaa mullite iyo silica xor ah ka dib kalsixin heerkul sare. Guud ahaan waxaa lagu soo saaraa sintering heerkul sare iyo slurry casting.
Astaamaha:Xasillooni kuleyl oo wanaagsan heerkulka sare, iska caabbinta nabaad-guurka dareeraha galaaska, wasakh yar oo ku timaadda dareeraha galaaska, waxayna inta badan ku habboon yihiin kanaalka quudinta, mashiinka quudinta, mashiinka jiidista tuubada iyo qalabka kale ee warshadaha galaaska, kuwaas oo si weyn u horumarin kara wax soo saarka.
Badeecadaha:Leben kanaalka, godka socodka, tuubada wareega, saxanka quudinta, giraanta daloolka, ul walaaqaya, feedh, dhululubo quudin, leben dab-damis ah, baloog qoyaan, leben qaanso ah, daboolka saxanka quudinta, lebenka godka dhex mara, lebenka gubanaya, alwaax, lebenka daboolka iyo noocyo kale iyo qeexitaanno kale.
