Kwiimeko ezininzi zoshishino, izixhobo zihlala zijongene neendawo ezahlukeneyo zokusebenza ezinzima, kwaye iingxaki zokuguguleka zichaphazela kakhulu ubomi benkonzo kunye nokusebenza kakuhle kwezixhobo. Ukuvela kwe-silicon carbide enganyangekiyo kuzisa isisombululo esisebenzayo kwezi ngxaki, kwaye kancinci kancinci iba sisikhuselo esiqinileyo sezixhobo zoshishino.
I-silicon carbide, i-compound eyenziwe ngekhabhoni kunye ne-silicon, ineempawu ezimangalisayo. Ubunzima bayo buphezulu kakhulu, bulandela idayimani enzima kakhulu, kwaye ubunzima bayo be-Mohs bulandela idayimani, oko kuthetha ukuba inokumelana lula nokukrweleka nokusikwa kwamasuntswana aqinileyo kwaye isebenza kakuhle ekuchaseni ukuguguleka. Kwangaxeshanye, i-silicon carbide ikwanayo ne-coefficient ephantsi yokuguguleka, enokulawula izinga lokuguguleka kwinqanaba eliphantsi kakhulu phantsi kweemeko ezinzima ezifana nokuguguleka okomileyo okanye ukuthambisa okungekho semgangathweni, okwandisa kakhulu ubomi benkonzo yezixhobo.
Ukongeza kubulukhuni kunye nomlinganiselo ophantsi wokungqubana, iipropati zeekhemikhali ze-silicon carbide nazo zizinzile kakhulu, kwaye azinazo iikhemikhali ezibalaseleyo. Iyakwazi ukumelana nokugqwala okuvela kwii-asidi ezinamandla (ngaphandle kwe-hydrofluoric acid kunye ne-hot concentrated phosphoric acid), iziseko ezinamandla, iityuwa ezinyibilikisiweyo, kunye neentsimbi ezahlukeneyo ezinyibilikisiweyo (ezifana ne-aluminium, i-zinc, i-copper). Olu phawu luyivumela ukuba isebenze ngokuzinzileyo nakwiindawo ezinzima apho i-corrosive media kunye nokuguguleka kuhlangana khona.
Ngokwembono yeempawu zobushushu nezomzimba, i-silicon carbide ikwabonisa ukusebenza kakuhle. Inomoya ophezulu wokuqhuba ubushushu kwaye ingasusa ngempumelelo ubushushu obuveliswa kukungqubana, iphephe ukuthamba kwezinto okanye ukuqhekeka koxinzelelo lobushushu okubangelwa kukushisa kakhulu kwezixhobo, kwaye igcina ukumelana okuhle kokuguguleka; I-coefficient yayo yokwandiswa kobushushu iphantsi kakhulu, enokuqinisekisa uzinzo olulinganayo lwezixhobo kwaye inciphise umonakalo woxinzelelo lobushushu kwizixhobo ngexesha lokutshintsha kobushushu. Ngaphezu koko, ukumelana nobushushu obuphezulu be-silicon carbide nako kuyamangalisa, kunye nobushushu bokusetyenziswa obufikelela kwi-1350 ° C emoyeni (kwindawo egcina i-oxidizing) kwaye iphezulu nangakumbi kwiindawo ezingasebenzi kakuhle okanye ezinciphisayo.
Ngokusekelwe kwiimpawu ezingasentla, i-lining enganyangekiyo ye-silicon carbide isetyenziswa kakhulu kumashishini amaninzi. Kwishishini lamandla, iipayipi ezisetyenziselwa ukuthutha izinto ezifana nothuthu oluphumayo zihlala zikhukuliswa ziingceba eziqinileyo ezihamba ngesantya esiphezulu, kwaye iipayipi zezinto eziqhelekileyo ziphela ngokukhawuleza. Nangona kunjalo, emva kokusebenzisa i-lining enganyangekiyo ye-silicon carbide, ukumelana nokuguguleka kwepayipi kuphucuka kakhulu, kwaye ubomi benkonzo buyandiswa kakhulu; Kwishishini lezemigodi, ukufakwa kwe-lining enganyangekiyo ye-silicon carbide kwizinto ezinganyangekiyo ezifana neepayipi ezihambisa udaka kunye ne-crusher interiors kunciphisa ukugcinwa kwezixhobo rhoqo kwaye kuphucula ukusebenza kakuhle kwemveliso; Kwishishini leekhemikhali, elijongene neendaba ezirhabaxa kunye neendawo ezintsonkothileyo ze-chemical reaction, i-lining enganyangekiyo ye-silicon carbide ayigcini nje ngokunganyangeki, kodwa ikwamelana nokugqwala kweekhemikhali ngempumelelo, iqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kwezixhobo.
Ngamafutshane, i-silicon carbide enganyangekiyo i-lining inika ukhuseleko oluthembekileyo kwizixhobo zoshishino ngenxa yokusebenza kwayo okugqwesileyo. Ngophuhliso oluqhubekayo lwesayensi yezinto, ukusebenza kwe-silicon carbide enganyangekiyo i-lining kuya kuqhubeka kuphuculwa, kwaye iindleko zinokuncitshiswa ngakumbi. Kwixesha elizayo, kulindeleke ukuba isetyenziswe kwiindawo ezininzi kwaye idlale indima enkulu ekusebenzeni kakuhle nangokuzinzileyo kwemveliso yezimboni.
