Corundum Mullite Castable Incazelo
I-Corundum mullite refractory castable iwuhlobo lwezinto eziphikisayo eziqinile ezingakakhiwe ezithengiswa ku-RS Company, ezingasetshenziswa kuhhavini lukasimende. Ama-castable e-Corundum mullite angenza izakhiwo eziphakeme njengamandla aphezulu okuchotshozwa, ukuzinza okuphezulu kwezinga lokushisa, ukumelana nokushisa okushisayo, ukuguga nokumelana nokuguguleka kwamakhemikhali olwelweni lwe-boiler esiteshini samandla amakhulu nezinye izinto zokushisa eziphakeme. i-refractory corundum mullite castable ingasetshenziswa esithandweni somlilo sensimbi, isithando sosimende, isithando somlilo sengilazi, isithando somlilo sokwenza insimbi, i-ceramic tunnel kiln nokunye.
Izindawo zokuhlala e- Corundum Mullite Castable
- Amandla aphezulu,
- Ukumelana nokugqoka okuqinile,
- Ukumelana kahle nokuguguleka,
- Ukuqina okuhle kakhulu kwe-thermal shock,
- Ukumelana nokushisa okuphezulu.
Inqubo Yokukhiqiza ye-Corundum Mullite Castable
Izinto zokusetshenziswa eziyinhloko ze-corundum mullite eziphonswayo i-aluminium oxide aggregate engasindi, i-ore yemvelo ehlanzekile ye-mullite yekhwalithi ephezulu, kanye nosimende we-calcium aluminate njenge-ejenti yokubopha. I-corundum mullite refractory castable yenziwa ngokushiswa kwezinga lokushisa eliphezulu ngesithando somlilo sezimboni. I-corundum mullite amandla aguquguqukayo namandla acindezelayo akhuphuka kuqala futhi anciphe bese ngokukhuphuka kwezinga lokushisa lokwelapha ukushisa. Futhi lapho okuqukethwe kwamandla amancane e-alumina kungu-5%, amandla okuguquguquka afinyelela phezulu.
Ukwakhiwa kweCorundum Mullite Castable
Okuqukethwe kwe-Al2O3 kungaphezu kuka-90%, futhi i-corundum mullite insulation incastable ne-corundum njengoba isigaba se-crystal esiyinhloko sixubene nama-dispersants afanelekile, ama-coagulants, imicu yensimbi engagqwali, ehlanganiswa ngokuvumelana nefomula eqinile. I-refractory corundum mullite castable inezici eziningi, njengamandla okushisa aphezulu, ukumelana nokugqoka kanye ne-anti-scour, ukushisa okuphezulu, ukumelana nokushaqeka kokushisa, ukumelana nokugqwala, ukuvala kahle kanye nokufiphala kwangaphambi kwesikhathi.

- Ukusetshenziswa kweCorundum Mullite Castable
- I-Corundum mullite refractory castable inezici zokunwetshwa okufanayo, ukumelana nokushaqeka okuhle kakhulu kwe-thermal, ukuzinza kwevolumu yokushisa okuphezulu, amandla okushisa aphezulu, ukungakhululeki okuphezulu ngaphansi komthwalo, izinga lokukhuphuka eliphansi lokushisa eliphezulu, amandla aphezulu okuchoboza, izinga lokushintsha komugqa ophansi, ubulukhuni obukhulu, okuhle. ukumelana nokugqwala kwamakhemikhali, ukubola kanye nokumelana nokugqoka. Ngenxa yezinhlamvu ezinjalo, futhi i-corundum mullite insulation incastable ihlala isikhathi eside isetshenziswa futhi isetshenziswa kabanzi kuhhavini lezimboni ezahlukene, isithando somlilo esishisayo nezinye izingxenye ezibalulekile zokushisa okuphezulu, njenge:
- I-boiler, isithando somlilo, isitofu esishisayo, isithando somlilo,
- Ihhavini le-Ceramic tonnel, ihhashi likasimende, isishishi samalahle,
- Umnyango wesithando somlilo, ukuvulwa kokuphakelayo, iziko lensimbi, iziko lensimbi,
