Inkcazelo yeCorundum Mullite Castable
I-Corundum mullite refractory castable luhlobo lwezixhobo ezingenakubunjwa eziqinileyo nezingenamilo ezithengiswayo kwi-RS Company, ezinokusetyenziswa kwi-oven yesamente. Ii-castable ze-Corundum mullite zinokwenza iipropati eziphezulu ezifana namandla aphezulu okutyumza, uzinzo kubushushu obuphezulu, ukumelana nobushushu, ukumelana nokuguguleka kunye nokukhukuliseka kweekhemikhali kwi-lining yebhoyila enkulu yesikhululo samandla kunye nezinye izixhobo zobushushu obuphezulu. I-corundum mullite refractory castable ingasetyenziswa kwi-oven yentsimbi, kwi-oven yesamente, kwi-oven yeglasi, kwi-oven yokwenza isinyithi, kwi-oven ye-ceramic tunnel njalo njalo.
Iipropati zeCorundum Mullite Castable
- Amandla aphezulu,
- Ukumelana nokuguguleka okunamandla,
- Ukumelana nokukhukuliseka okuhle,
- Uzinzo oluhle kakhulu lobushushu,
- Ukumelana nobushushu obuphezulu.
Inkqubo yokuvelisa iCorundum Mullite Castable
Izinto eziphambili ezisetyenziswa kwi-corundum mullite castable yi-aluminium oxide aggregate elula, i-mullite ore yendalo ecocekileyo esemgangathweni ophezulu, kunye ne-calcium aluminate cement njenge-bonding agent. I-corundum mullite refractory castable yenziwa ngokutshiswa kobushushu obuphezulu yi-industrial furnace ephambili. Amandla e-corundum mullite flexural kunye namandla okuxinzelela ayanda kuqala aze anciphe emva koko ngokonyuka kobushushu bonyango lobushushu. Kwaye xa umxholo wamandla amancinci e-alumina uyi-5%, amandla e-flexural afikelela phezulu.
Ukwakhiwa kweCorundum Mullite Castable
Umxholo we-Al2O3 ungaphezulu kwe-90%, kwaye i-corundum mullite insulation castable kunye ne-corundum njengesigaba esiphambili sekristale ixutywe nee-dispersants ezifanelekileyo, ii-coagulants, iifayibha zentsimbi engagqwaliyo, ezidityaniswe ngokwefomula engqongqo. I-corundum mullite castable erhabaxa ineempawu ezininzi, ezinje ngamandla obushushu aphezulu, ukumelana nokuguguleka kunye nokuchasana nokukhuhla, ukuqhuba ubushushu okuphezulu, ukumelana nobushushu, ukumelana nokugqwala, ukuvalwa kakuhle kunye nokufuma kwangoko.

Ukusetyenziswa kweCorundum Mullite Castable
I-Corundum mullite refractory castable ineempawu zokwandiswa okufanayo, ukumelana nokutsha kobushushu obuphezulu, ukuzinza kobushushu obuphezulu, amandla aphezulu obushushu, ukumelana okuphezulu phantsi komthwalo, izinga eliphantsi lokuhamba kobushushu obuphezulu, amandla aphezulu okutyumza, izinga eliphantsi lokutshintsha komgca, ubulukhuni obuphezulu, ukumelana okuhle nokugqwala kweekhemikhali, ukuchasana nokuguguleka. Ngenxa yezi mpawu, i-corundum mullite insulation castable ihlala ixesha elide kwaye isetyenziswa kakhulu kwii-oven ezahlukeneyo zoshishino, iziko lobushushu obuphezulu kunye nezinye iindawo ezibalulekileyo zobushushu obuphezulu, ezifana:
- Ibhoyila, isitovu somlilo oqhumayo, isitovu somlilo oshushu, isitovu somlilo oshushu,
- Isitovu somjelo weseramikhi, isitovu sesamente, isitshisi samalahle,
- Ucango lwesithando somlilo, ukuvulwa kokutya, izithando zentsimbi, izithando zokwenza intsimbi,
- Igumbi lokutsha, umbhobho othe tyaba,
- Ibhoyila yesitishi samandla esikhulu, i-oven yeglasi.
