Sintered Tabular Alumina Inkcazo
I-tabular corundum, kwaziwa njengesintered tabular alumina, i-high-purity form of alumina (Al2O3) ecutshungulwa ngokukodwa ukuba ibe ne-aItheyibhile eyodwa, okanye imilo emcaba.Iveliswa nge-sintering (ukufudumala ngaphandle kokunyibilika) i-alumina powder ephezulu kwiqondo lokushisa ngaphezu kwe-1900 ° C, ebangela ukuba iinqununu ze-alumina zikhule kwaye zenze i-crystals enkulu, i-flat, i-plate-like.

| Ukusetyenziswa: I-tabular corundum isetyenziswa ngokubanzi kwizixhobo eziphezulu zokusebenza kwi-refractory kwimimandlaintsimbi, ukugalela, iikhemikhali zepetroli, izitena eziphefumlayo, iileyiti zeladi, izinto eziphoswayo, iindawo ezenziweyo, iiseramikhi kunye nezinye iindawo..Yimathiriyeli egqibeleleyo yerefractory egqwesileyo.I-tabular corundum isetyenziswa njengeUdityaniso lwe-refractoryingasetyenziselwa ngokudibanisa ne-spinel, i-alumina ene-calcined esebenzayo kunye nee-agent zokubopha ezifana ne-samente, udongwe okanye i-resin.Izitena ezilungiselelwe ukucoceka okuphezulu kwe-corundum zinomxholo ophantsi wokungcola (okufana ne-SiO2), ubuninzi obuninzi kunye neempawu ezintle ze-thermodynamic, ukwenza izitena ze-corundum Izitena zichasene nomonakalo obushushu, iikhemikhali kunye nezakhiwo ezibangelwa kukusebenza kwe-gasifiers kunye nezinye iziko zoshishino. | ||
| Iingenelo:i-refractoriness ephezulu;ukuxhathisa okuphezulu kwe-corrosion;ukumelana nokukhukuliseka okuphezulu;ukuxhathisa ukothuka okuphezulu kwe-thermal;amandla aphezulu, ukuqina okuhle;iipropati ezizinzileyo zeekhemikhali;ukuchasana nokukhukuliseka kwe-alkaline ye-slag, ukuchasana kakuhle nokhukuliseko lwe-slag, kunye nokumelana kakuhle nokhukuliseko lwentsimbi enyibilikisiweyo;Ukumelana nokhukuliseko yintsimbi etyhidiweyo kunye nokungena komoya okulungileyo. | ||
