Isitini se-Corundum mullite uhlobo lwesitini esiphikisayo esenziwe ngezinto zokusetshenziswa ezihlanzekile noma ezihlanzekile, futhi ibhlogo le-corundum mullite liyisitini somlilo se-alumina esiphezulu esenziwe nge-corundum kanye ne-mullite main crystalline phase. Izinto eziyinhloko zesitini se-corundum mullite zingeniswa epuletini le-corundum, i-corundum ehlanganisiwe ehlanzekile ephezulu, yamukela ubuchwepheshe obuthuthukisiwe bokwengeza i-superfine powder, yenziwa ngezinto zokuxuba, zomisa, zibumba futhi zishiswe kuhhavini we-shuttle oshisayo ophezulu.
Izici Zezitini zeCorundum Mullite
- Izinto zokusetshenziswa ezisezingeni eliphezulu,
- I-corundum ehlanzekile kakhulu,
- Ukuqina kwevolumu okuqinile emazingeni okushisa aphezulu,
- Ibunjwe ngokucindezela okuphezulu kanye nokushisa okuphezulu,
- Ukumelana okuhle nokushaqeka kokushisa,
- Ukumelana nokugqoka,
- Ukumelana nokuhlaselwa ngamakhemikhali.
Inqubo Yokukhiqiza Izitini zeCorundum Mullite
Izitini ze-Corundum mullite zenziwe ngezitini ze-mullite zokwenziwa kanye nezinhlayiya ze-mullite ezihlanganisiwe ziyatholakala, kanti i-alpha Al2O3 powder yempuphu, ingahlanganiswa noma ixutshwe nezinhlayiya ze-corundum ukuze ihlanganiswe, i-synthetic mullite powder yempuphu. I-aggregate kanye nempuphu kuxutshwa ngokwesilinganiso esithile kanye nosayizi wezinhlamvu. Utshwala obungcolile be-pulp yephepha ene-sulfite busetshenziswa njenge-ejenti yokubopha, futhi izinto zengezwa ngokulandelana okuthile. Kuxutshwe ngokuphelele futhi kulingane, ngomshini wokubumba izitini noma umshini wokubumba izitini we-hydraulic. I-Adobe ngemuva kokomiswa, shiswa ku-1650 ~ 1750 ℃.
Imininingwane Yezitini ze-Rongsheng Refractory Corundum Mullite
| Izinto | Okumsulwa Okuphezulu Nekhwalithi Ephezulu Isitini se-Corundum esihlanganisiwe | Isitini se-Sintered Corundum | Isitini se-Mullite-Corundum |
| I-Al2O3 % | ≥99 | ≥90 | ≥80 |
| I-SiO2 % | ≤0.2 | ≤8 | ≤18 |
| I-Fe2O3 % | ≤0.2 | ≤0.2 | ≤0.3 |
| Ubuningi g/cm3 | ≥3.2 | ≥3 | ≥2.8 |
| Ukuvuleka okubonakalayo % | ≤19 | ≤18 | ≤18 |
| Amandla okucindezela abandayo i-MPa | ≥100 | ≥100 | ≥100 |
Intengo Yezitini zeCorundum Mullite
Ngokuvamile, izitini ze-cordundum mullite zihlukaniswe ngezitini ezihlanganisiwe nezihlanganisiwe, intengo yezitini ezimbili ze-corundum mullite eziphikisanayo ihluke kakhulu emakethe, intengo isukela ezinkulungwaneni kuya ku-10,000. Siphakamisa ukuthi izitini ezahlukene ze-corundum mullite zomlilo kufanele zikhethwe ngokwezingxenye ezahlukene zesithando somlilo, hhayi nje ukuthuthukisa impilo yesithando somlilo, kodwa futhi nokunciphisa izindleko.
Ukusetshenziswa Kwesitini Se-Corundum Mullite Sesithando Somlilo
Isitini se-Cordundum mullite singathintana ngqo nelangabi, ukumelana nokuqhekeka, ukumelana nokushisa okuphezulu, singasetshenziswa njengokuvimbela ukushisa kwendwangu yesithando somlilo sezimboni esishisa kakhulu. Futhi isitini somlilo se-corundum mullite singasetshenziswa njengenye ingqimba yokusebenza yesithando somlilo sezimboni, esetshenziswa kakhulu embonini ye-petrochemical, i-ammonia gasifier enkulu nephakathi nendawo kanye nezinto ezisebenza ngogesi zesithando somlilo segesi ezinempahla, izinto zokwakha isithando somlilo sezimboni esishisa kakhulu, njll.
