Kwicandelo lobushushu obuphezulu kwimizi-mveliso, ukufikelela ekudluliseleni ubushushu ngokukhuselekileyo nangokufanelekileyo bekusoloko kungundoqo kwimpumelelo yezobuchwepheshe.Ityhubhu yemitha ye-silicon carbidesisixhobo esikhethekileyo esenzelwe ngokukodwa iimeko zobushushu obuphezulu. Sisebenza njengesixhobo sokuthutha amandla obushushu obuphezulu esithuleyo kwaye sidlala indima ebalulekileyo ngokuthe cwaka kwizitofu zokufudumeza kumashishini afana ne-metallurgy, ubunjineli beekhemikhali, kunye neeseramikhi. Masityhile imfihlakalo yomgaqo wayo wokusebenza ngeembono ezintathu eziphambili.
1, Umqobo oqinileyo wokukhusela umbindi
Izinto ezingaphakathi ezingundoqo zetyhubhu yemitha ye-silicon carbide zisongelwe ngononophelo kwityhubhu yangaphandle eyenziwe ngezinto ze-silicon carbide, zenza ukhuseleko oluphindwe kabini: ityhubhu ye-silicon carbide yangaphandle isebenza njengomthwali wemitha yobushushu kunye nomqobo wokhuseleko, iqinisekisa ukuba izinto zokufudumeza zangaphakathi zahlulwe ngokupheleleyo kwindawo yesithando. Ayipheleli nje ekwandiseni ubomi beetyhubhu zemitha ye-silicon carbide ngokufanelekileyo, kodwa ikwanciphisa kakhulu iindleko zokulungisa.
2, indlela eyahlukileyo yokudlulisa ubushushu
Ngokungafaniyo nokuqhuba ubushushu bendabuko, inzuzo ephambili yezixhobo ezinjalo ikukudluliselwa "kwemitha yobushushu". Umphezulu wetyhubhu ye-silicon carbide efudunyezwa ukuya kwimeko ye-incandescent uya kukhupha amaza okukhanya kwe-infrared ngaphandle rhoqo. Olu kukhanya lungabonakaliyo lunokungena emoyeni kwaye lusebenze ngokuthe ngqo kwinto eshushu, ngendlela efana nendlela ilanga elifudumeza ngayo umhlaba. Ukudluliselwa kobushushu obukhanyayo kuthintela ukulahleka okuphakathi, kuphucula kakhulu ukusebenza kakuhle kobushushu xa kuthelekiswa nokufudumala okuqhelekileyo, kwaye kukhokelela ekusasazweni kobushushu obufanayo.
3, Ukuphuculwa kwekristale kwisayensi yezinto
Ukukhethwa kwe-silicon carbide (SiC), uhlobo olutsha lwezinto ze-ceramic, kunokubonwa njengento yokugqibela. Ukumelana kwayo nobushushu obuphezulu kuvumela umzimba wepayipi ukuba usebenze ngokuqhubekayo kwi-1350 ℃, kwaye amandla ayo aphindwe kaninzi kunentsimbi eqhelekileyo; Isakhiwo sekristale esikhethekileyo sizisa ukumelana okuhle kakhulu nobushushu, nokuba emva kokuba iphole ngequbuliso kwaye ifudumale, ayizukuqhekeka; Ikwanazo neempawu zokulwa nokugqwala kwaye inokusingatha iimozulu ezahlukeneyo zokugqwala kwemizi-mveliso ngokulula. Ezi mpawu xa zidibene zakha isiseko sobomi benkonzo ende yesixhobo.
Ngenxa yokwanda kwemfuno yemveliso ecocekileyo, iityhubhu zemitha ye-silicon carbide ziya zithatha indawo yeetyhubhu zokufudumeza zesinyithi zemveli kwaye ziba lukhetho olutsha lokuphucula izixhobo zobushushu zoshishino. Uyilo lwayo olutsha "lokufudumeza okwahlukileyo kunye nokudluliselwa kwamandla emitha" kunciphisa kakhulu iindleko zokugcina ngelixa kuphucula ukusebenza kakuhle kwamandla, kubonelela ngenkxaso yobugcisa ethembekileyo yokuguqulwa okuluhlaza kwishishini lokuvelisa. Lo msebenzi wobugcisa wezemveliso odibanisa ngokugqibeleleyo iipropati zezinto kunye nemigaqo yokudluliselwa kobushushu uchaza ngokutsha umgangatho weshishini lokufudumeza obushushu obuphezulu.
