Corundum-mullite Chute

IiCeramics zeAlumina

I-Alumina Ceramics yeyona nto isetyenziswa kakhulu kwi-ceramic imathiriyeli ephezulu. Ngenxa yebhondi yayo eyomeleleyo ye-ionic inter-atomic, i-alumina ibonelela ngokusebenza kakuhle ngokwemichiza kunye nokuzinza kwe-thermal, ukomelela okulungileyo, iimpawu zokugquma kwe-thermal kunye nombane ngexabiso elifanelekileyo. Ngoluhlu lokucoceka kunye nexabiso eliphantsi ngokwentelekiso kwimveliso yemathiriyeli ekrwada kuyenzeka ukuba kusetyenziswe i-alumina kwizicelo ezahluka-hlukeneyo kumashishini ahlukeneyo.

Mullite Ceramics Alumina

I-Mullite yenzeka ngokunqabileyo kakhulu kwindalo kuba yenza kuphela kubushushu obuphezulu, iimeko zoxinzelelo oluphantsi, ngoko ke njengeminerali yeshishini, i-mullite kufuneka inikezelwe ngezinye iindlela zokwenziwa. I-Mullite yimathiriyeli eyomeleleyo yomgqatswa we-ceramics ephucukileyo kwinkqubo yoshishino kwiipropathi zayo ezithandekayo ze-thermal kunye ne-mechanica: ukwanda kwe-thermal ephantsi, i-thermal conductivity ephantsi, ukuxhathisa okugqwesileyo okuhambayo, amandla afanelekileyo obushushu obuphezulu kunye nozinzo olubalaseleyo phantsi kweemeko zemichiza enzima.

I-Alumina exineneyo kunye neCordierite exineneyo

Ukufunxa amanzi asezantsi (0-5%)

Ukuxinana okuphezulu, Umthamo wobushushu obuphezulu

Indawo enkulu yendawo ethile, ukusebenza kakuhle kwe-thermal

I-anti-asidi enamandla, i-anti-silicon, i-anti-salt. Izinga lebhloko ephantsi

IiCeramics zeSilicon Carbide

I-silicon carbide iphawuleka ngenxa yobunzima bayo, indawo ephezulu yokunyibilika kunye ne-thermal conductivity ephezulu. Iyakwazi ukugcina amandla ayo kubushushu obuphezulu ukuya kuthi ga kwi-1400 °C kwaye inikezela ngokumelana okugqwesileyo kokunxiba kunye nokumelana nokothuka kwe-thermal. Ineemveliso ezisekwe ngokufanelekileyo kwaye zisasazeke ngokubanzi njengenkxaso ye-catalyst kunye negesi eshushu okanye izihluzo zetsimbi ezinyibilikisiweyo ngenxa ye-coefficient yayo ephantsi yokwandiswa kwe-thermal kunye nokumelana nokutshatyalaliswa kwe-thermal-shock kunye nokuzinza okugqwesileyo komatshini kunye neekhemikhali kwiindawo eziphakamileyo zokushisa.

IiCeramics zeCordierite

I-Cordierite inokumelana nokothuka kwe-thermal ngenxa ye-intrinsic low coefficient of thermal expansion (CET), idityaniswa nokuchasana okuphezulu kunye nokuzinza okuphezulu kweekhemikhali. Ngoko ke, isoloko isetyenziswa njengezicelo zobushushu obuphezulu, ezifana nezi: abatshintshi bobushushu kwiinjini ze-injini ye-gas; i-honeycomb-shaped catalyst carriers kwinkqubo yokukhupha imoto.

Zirconia Oxide Ceramics Corundum

I-Ceramics Zirconia ingaba yinto efanelekileyo yokuqina okuphezulu kunye nokuqina okuphezulu xa iingoma ezifanelekileyo, ezifana ne-magnesium oxide (MgO), i-yttrium oxide, (Y2O3), okanye i-calcium oxide (i-CaO), yongezwa ukulawula ukuguqulwa kwesigaba esiyingozi. izicelo.

IiCeramics zaseCorundum

1. ukucoceka okuphezulu: Al2O3> 99%, ukuchasana kweekhemikhali okulungileyo

2. ukumelana nobushushu, ukusetyenziswa kwexesha elide kwi-1600 °C, 1800 °C yexesha elifutshane

3. ukuxhathisa ukothuka kwe-thermal kunye nokumelana kakuhle nokuqhekeka

4. ukuphosa ukutyibilika, ukuxinana okuphezulu, ukucoceka okuphezulu kwe-alumina
