Zirconium Mullite Brick
Zirconium Mullite Brick
Zvigadzirwa zvigadzirwa: yakakwira huwandu hwakawanda, hombe vhoriyamu, yakakwira michini simba patembiricha tembiricha uye yakanyanya tembiricha, yakanaka yekupisa yekuvhunduka kugadzikana, yakaderera yekudzorerazve shrinkage uye yakanyanya tembiricha zvinokambaira, uye yakanaka makemikari kugadzikana uye kuramba kune alkaline midhiya.
Supply mukana: Fully otomatiki akangwara refractory kugadzirwa mutsetse, nyika dhirivahari
Chigadzirwa kunoshandiswa: Inonyanya kushandiswa muzvikamu zvakakosha zvemakirniki akadai segirazi kilns, girazi fiber kilns, dombo shinda fiber kilns, marara anopisa kilns, zvedongo frit glaze kilns, mavira emagetsi, nezvimwe.
chigadzirwa tsanangudzo
Zirconium mullite zvidhinha inovandudza chimiro chemullite nekuunza ZrO2 kuita A12O3-SiO2 zvidhinha, izvo zvinogona kugadzirisa kushomeka kwemakemikari, kupisa kwemhepo uye kudzikamisa kuenzana kwekuwedzera kwemullite. Inowanzoitwa neelectrofusion. Iyo zvakare inogadzirwa neiyo sintering nzira.
Zirconium mullite zvidhinha chinhu chakakosha chinogadziriswa chinoitwa nekushandisa maindasitiri alumina uye zircon inosimbisa sezvinhu zvakagadzirwa uye kuunza zirconia mune mullite matrix kuburikidza neyakagadziriswa sintering maitiro.
Zirconium mullite zvidhinha zvinounza zirconia kuita mullite zvidhinha, uye chikamu shanduko kuomerera kwe zirconia kunogona kuvandudza zvakanyanya iyo yepamusoro-tembiricha mega zvivakwa zvemullite zvigadzirwa. Zirconia inosimudzira iyo sintering yezvinhu zvemullite. Kuwedzeredzwa kweZrO2 kunogona kukudza iyo densification uye sintering maitiro eZTM zvigadzirwa nekuda kwechizvarwa chekuderera kwakatsetseka nzvimbo zvinhu uye kuumbwa kwenzvimbo. Kana chikamu chakakura che zirconium mullite chidhinha chiri 30%, iyo hama dzidziso yehuremu hwegirini mutumbi unodzingwa pa1530 ° C unosvika 98%, simba rinosvika 378MPa, uye kuoma kunosvika 4.3MPa · m1 / 2.
Zirconium mullite zvidhinha zvinogadzirwa kubva kumaindasitiri alumina uye zircon nekuita sintering. Nekuti iko kuita uye kutsvaira kunoitwa panguva imwe chete, maitiro ekugadzirisa akaoma. Kazhinji, zirconium mullite zvidhinha zvinopisa pa1450 ° C kuti zviite kuti densified panguva yekupfura, uye zvobva zvatsamwa kusvika 1600 ° C yekuita. ZrSiO4 inoora kuita ZrO2 neSiO2 patembiricha iri pamusoro pe1535 ° C, uye SiO2 neAl2O3 zvinoita kuumba mullite Dombo, nekuti chikamu chechikamu chemvura chinoonekwa panguva yekuora kweZrSiO4, uye kuora kweZrSiO4 kunogona kunatsiridza zvidimbu, kuwedzera iyo chaiyo yepamusoro nzvimbo, uye kusimudzira sintering.
