Ezimweni eziningi zezimboni, imishini imvamisa kufanele ibhekane nezindawo zokusebenza ezinokhahlo ezahlukahlukene, futhi izinkinga zokuguga zithinta kakhulu impilo yesevisi nokusebenza kahle kwemishini. Ukuvela kwe-silicon carbide-resistant lining kunikeza isisombululo esisebenzayo kulezi zinkinga, futhi kancane kancane iba isihlangu esiqinile semishini yezimboni.
I-silicon carbide, inhlanganisela eyakhiwe nge-carbon ne-silicon, inezici ezimangalisayo. Ukuqina kwayo kuphakeme kakhulu, okwesibili ngemva kwedayimane elinzima kunawo wonke emvelweni, futhi ubulukhuni bayo be-Mohs bungokwesibili ngemva kwedayimane, okusho ukuthi ingamelana kalula nokuklwebheka nokusikwa kwezinhlayiya ezihlukahlukene ezinzima futhi yenze kahle ukumelana nokugqoka. Ngesikhathi esifanayo, i-silicon carbide nayo ine-coefficient ephansi yokungqubuzana, engalawula izinga lokugqoka ezingeni eliphansi kakhulu ngaphansi kwezimo ezinzima ezifana nokungqubuzana okomile noma ukugcotshwa okungalungile, okunweba kakhulu impilo yesevisi yemishini.
Ngaphezu kokuqina kanye ne-coefficient ephansi yokungqubuzana, izakhiwo zamakhemikhali ze-silicon carbide nazo zizinzile kakhulu, zine-inertness yamakhemikhali enhle kakhulu. Inokumelana okuqinile nokugqwala okuvela kuma-asidi aqinile (ngaphandle kwe-hydrofluoric acid ne-hot concentrated phosphoric acid), izisekelo eziqinile, usawoti oncibilikisiwe, nezinsimbi ezihlukahlukene ezincibilikisiwe (njenge-aluminium, i-zinc, ithusi). Lesi sici siyivumela ukuthi isebenze ngokuzinza ngisho nasezimweni ezinzima lapho imidiya egqwalayo kanye nokugqokwa kuhlangana khona.
Ngokombono wezakhiwo ezishisayo nezomzimba, i-silicon carbide nayo ikhombisa ukusebenza okuhle kakhulu. Ine-conductivity ephezulu yokushisa futhi ingasusa ngokuphumelelayo ukushisa okukhiqizwa ukungqubuzana, ukugwema ukuthambisa izinto ezibonakalayo noma ukuqhekeka kokucindezeleka okushisayo okubangelwa ukushisa okweqile kwendawo kwemishini, nokugcina ukumelana nokugqoka okuhle; I-coefficient yayo yokwanda okushisayo iphansi kakhulu, engaqinisekisa ukuzinza kwe-dimensional kwemishini futhi inciphise ukulimala kokucindezeleka okushisayo kumishini ngesikhathi sokushintshashintsha kwezinga lokushisa. Ngaphezu kwalokho, ukumelana nokushisa okuphezulu kwe-silicon carbide nakho kuvelele, ngezinga lokushisa lokusetshenziswa elifinyelela ku-1350 ° C emoyeni (indawo ene-oxidizing) futhi liphakeme nakakhulu ezindaweni ezingenzi lutho noma ezinciphisayo.
Ngokusekelwe kulezi zici ezingenhla, i-silicon carbide-resistant lining isetshenziswe kabanzi ezimbonini eziningi. Embonini kagesi, amapayipi asetshenziswa ukuthutha izinto ezinjengomlotha wezimpukane avame ukukhukhulwa yizinhlayiya eziqinile ezigeleza ngesivinini esikhulu, namapayipi ajwayelekile aguga ngokushesha. Kodwa-ke, ngemva kokusebenzisa i-silicon carbide-resistant lining, ukumelana nokugqokwa kwepayipi kuthuthukiswa kakhulu, futhi impilo yesevisi inwetshwa kakhulu; Embonini yezimayini, ukufakwa kwe-silicon carbide-resistant lining ezingxenyeni ezingagugi njengamapayipi ahambisa udaka kanye nezinto zangaphakathi ze-crusher kunciphisa imvamisa yokugcinwa kwemishini futhi kuthuthukisa ukusebenza kahle kokukhiqiza; Embonini yamakhemikhali, ebhekene nemithombo yezindaba ebolayo kanye nezimo eziyinkimbinkimbi zokusabela kwamakhemikhali, ulwelwesi olungagugiyo lwe-silicon carbide alugcini nje ukumelana nokugqoka, kodwa futhi lumelana ngokuphumelelayo nokugqwala kwamakhemikhali, luqinisekisa ukusebenza okuphephile nokuzinzile kwemishini.
Kafushane, i-silicon carbide-resistant lining ihlinzeka ngokuvikeleka okuthembekile kwemishini yezimboni ngokusebenza kwayo okuhle kakhulu. Ngokuthuthuka okuqhubekayo kwesayensi yezinto, ukusebenza kwe-silicon carbide-resistant lining kuzoqhubeka nokuthuthukiswa, futhi izindleko zingase zehliswe nakakhulu. Ngokuzayo, kulindeleke ukuthi isetshenziswe emikhakheni eminingi futhi ibambe iqhaza elikhulu ekusebenzeni okusebenzayo nokuzinzile kokukhiqizwa kwezimboni.
