I-Silicon carbide (SiC) ibonisa ukuguga okuvelele nokumelana nokugqwala ngenxa yezakhiwo zayo ezihlukile zomzimba namakhemikhali.
Mayelana nokumelana nokugqokwa, ubulukhuni be-Mohs be-silicon carbide bungafinyelela ku-9.5, okwesibili ngemuva kwedayimane ne-boron nitride. Ukumelana nokugqokwa kwayo kulingana nokuphindwe ka-266 okwensimbi ye-manganese kanye nezikhathi ezingu-1741 kune-chromium cast iron ephezulu.
Mayelana nokumelana nokugqwala, i-silicon carbide inokuqina okuphezulu kakhulu kwamakhemikhali futhi ikhombisa ukumelana okuhle kakhulu nama-acids aqinile, ama-alkali, nezixazululo zikasawoti. Ngaleso sikhathi, i-silicon carbide nayo inokumelana nokugqwala okuphezulu kwezinsimbi ezincibilikisiwe njenge-aluminium ne-zinc, futhi ivame ukusetshenziswa kuma-crucibles kanye nesikhunta embonini ye-metallurgical.
Njengamanje, i-silicon carbide ehlanganiswe nesakhiwo esiqinile kakhulu kanye nokungabi namandla kwayo kwamakhemikhali sekusetshenziswe kabanzi ezimbonini ezifana nezimayini, insimbi, namakhemikhali, iba yinto ekahle yokukhetha ngaphansi kwezimo zokusebenza ezinzima.
| impahla | ukumelana nokugqoka | ukumelana nokugqwala | ukusebenza kwezinga lokushisa eliphezulu | Ezomnotho (isikhathi eside) |
| I-silicon carbide | Iphakeme kakhulu | Iqine ngokwedlulele | Kuhle kakhulu (((1600℃) | Phezulu |
| I-Alumina Ceramics | Phezulu | Iqinile | Isilinganiso (((1200℃) | Maphakathi |
| Ingxubevange yensimbi | Maphakathi | Ibuthakathaka (idinga ukunamathela) | Okubuthakathaka (okuthambekele ekungeneni kwe-oxidation) | Buthaka |
I-silicon carbide-resistant block blockiyisigaba esibalulekile emikhiqizweni ye-silicon carbide.Izakhiwo ze-silicon carbide ezingagugi futhi ezimelana nokugqwala ziyenza isetshenziswe kabanzi emishinini yokugaya njengama-crushers emayini kanye nezigayo zamabhola, ukunciphisa ukushintshwa kwemishini njalo okubangelwa ukuguga futhi ngaleyo ndlela kwehlise izindleko zokulungisa umshini.
Okulandelayo ukuqhathanisa phakathi kwamabhulokhi e-silicon carbide angagugi kanye namanye amabhulokhi wendabuko angagugi:
| Ukuqina Nokumelana Nokugqoka | I-silicon carbide-resistant block block | Izinto zendabuko |
| Ukuqina Nokumelana Nokugqoka | Ubulukhuni be-Mohs 9.5, ukumelana nokugqoka okunamandla kakhulu (impilo ikhuphuke izikhathi ezingu-5-10) | I-chromium cast iron ephezulu inokuqina okuphansi (HRC 60~65), futhi izitsha zobumba ze-alumina zijwayele ukuqhekeka. |
| Ukumelana nokugqwala | Imelana nama-asidi aqinile nama-alkali | Izinsimbi zijwayele ukugqwala, kuyilapho i-alumina ine-avareji yokumelana ne-asidi |
| Ukuqina kwezinga lokushisa eliphezulu | Izinga lokushisa ukumelana 1600 ℃, non oxidizing emazingeni okushisa aphezulu | Insimbi ijwayele ukuguquka emazingeni okushisa aphezulu, kuyilapho i-alumina inokumelana nezinga lokushisa elingu-1200 ℃ kuphela. |
| I-Thermal conductivity | 120 W/m · K, ukushabalaliswa kokushisa okusheshayo, ukumelana nokushaqeka okushisayo | I-Metal ine-thermal conductivity enhle kodwa ijwayele ukungena kwi-oxidation, kuyilapho izitsha zobumba ezivamile zine-thermal conductivity engalungile. |
| Ezomnotho | Ukuphila okude kanye nezindleko eziphansi | Izinsimbi zidinga ukushintshwa njalo, izitsha zobumba zintekenteke, futhi izindleko zesikhathi eside ziphezulu |
