Mullite tiav
1. Tsawg creep mullite cib
Siv hluavtaws mullite clinker, super siab bauxite clinker li raw khoom, ntxiv ib co siab purity quartz thiab additives, tsawg creep mullite cib yuav ua tau.
Lub molding yog nqa tawm ntawm 300t kev sib txhuam xovxwm. Qhov ceev ntawm lub billet yuav tsum tau tswj siab tshaj 2.70g / cm3. Lub tshuab ziab khaub ncaws qhuav ntawm 50 ~ 110 degree thiab lub sijhawm ziab yog 16h. Cov dej seem ntawm lub cev tom qab ziab yuav tsum tsawg dua 0.5 feem pua. Qhov siab tshaj plaws tua hluav taws kub ntawm cov khoom yog 1600 degree, thiab lub tshav kub preservation yog 16h. Lub cev indexes ntawm cov khoom yog raws li nram no: pom porosity 19 ~ 21 feem pua; Qhov ntom ntom 2.55 ~ 2.60g / cm3; Compressive zog 69 ~ 116MPa; 1450 degree, 50h siab nkag tus nqi 0.12 feem pua.
2. Tsawg creep sintered mullite cib
Sintered mullite cib tuaj yeem tsim los ntawm kev siv andalusite ua aggregate, sillimanite li nruab nrab particle, sillimanite hmoov, bauxite hmoov, muaj alumina hmoov thiab av nplaum hmoov ua substrate.
Qhov kub ntawm sintering yog 1490 degree, tuav rau 19h, qhov porosity ntawm cov khoom tuaj yeem ncav cuag 17.15 feem pua, qhov ntom ntom yog 2.53g / cm3, lub zog siab ntawm chav tsev kub yog 136.5MPa, thiab cov khoom muag muag kub yog 1627 degree. Ntawm 1450 degree, tus nqi nkag tuaj yeem ncav cuag 0.87 feem pua rau 50h. Yog tias qhov hluav taws kub kub yog 1450 degree thiab lub sijhawm tuav tau txuas ntxiv mus rau 26h, lub hom phiaj ntawm sintering tuaj yeem ua tiav. Txawm li cas los xij, qhov Performance index ntawm lub cev yog qis dua li ntawm cov khoom raug rho tawm haujlwm ntawm 1490 degree. Piv txwv li, ntawm 1450 degree, tus nqi nkag rau 50h yog 0.98 feem pua.
