I-Mullite light-weight insulation izitini
Incazelo Yomkhiqizo
Izitini ze-mullite ezinesisindo esincane ziqukethe i-porosity ephezulu, engasindisa ukushisa okwengeziwe futhi ngenxa yalokho inciphisa izindleko zikaphethiloli.Okwamanje isisindo esilula sisho umthamo omncane wokugcina ukushisa, ngakho-ke sincane isikhathi esidingekayo lapho ihhashi lishisisa noma lipholiswa.Ukusebenza ngezikhathi ezithile okusheshayo kuyasebenza.
Ingasetshenziswa ebangeni lokushisa kusuka ku-900 kuya ku-1600 ℃.
Isetshenziswa kakhulu njengeziko lomlilo ekushiseni okuphezulu (ngaphansi kuka-1700 ℃) amakhilo e-ceramics, i-petrochemical, i-metallurgy nemishini.
Izici Ezijwayelekile
I-conductivity ephansi ye-thermal, umthamo ophansi wokushisa, okuqukethwe kokungcola okuphansi
Amandla aphezulu, ukumelana nokushaqeka okushisayo okuhle kakhulu, ukumelana nokuguguleka
Ubukhulu obunembile
Uhlelo lokusebenza olujwayelekile
I-Ceramics roller kiln kanye ne-shuttle kiln: isitini esijwayelekile, isitini sembobo ye-roller, isitini se-hanger,
Imboni ye-Metallurgy: isithando somlilo esishisayo;ulwelwesi lwangaphakathi lwamahhanela
Imboni yamandla: ukukhiqiza amandla kanye nemishini yokulala efakwe amanzi
Imboni ye-Aluminium ye-Electrolytic: ulayini lwangaphakathi lweziko
