Munyaya dzekupisa kwakanyanya kwemaindasitiri, kuwana kutamiswa kwekupisa kwakachengeteka uye kunoshanda kwagara kuri kiyi yekubudirira kwetekinoroji.Chubhu yemwaranzi yesilicon carbidemudziyo wakakosha wakagadzirirwa mamiriro ekupisa kwakanyanya. Unoshanda se "mutakuri wesimba rekupisa" wakanyarara uye unoshanda chinyararire mukupisa maovheni mumaindasitiri akadai sesimbi, makemikari, uye zviumbwa zvedongo. Ngatibudisei chakavanzika chekushanda kwayo kuburikidza nemaonero matatu makuru.
1, Chidziviriro chakasimba chekudzivirira core
Zvikamu zvemukati zvechubhu yemwaranzi yesilicon carbide zvakaputirwa zvakanyatsonaka muchubhu yekunze yakagadzirwa nezvinhu zvesilicon carbide, zvichiita dziviriro mbiri: chubhu yekunze yesilicon carbide inoshanda senzira yekutakura mwaranzi yekupisa uye sechidziviriro chekuchengetedza, ichivimbisa kuti zvinhu zvemukati zvekupisa zvabviswa zvachose kubva munzvimbo yechoto. Hazvingorevi chete kuti zvinongowedzera hupenyu hwechubhu yemwaranzi yesilicon carbide, asi zvinoderedzawo zvakanyanya mari yekugadzirisa.
2, Nzira yakasiyana yekushandura kupisa
Kusiyana nekupisa kwechinyakare, mukana mukuru wemidziyo yakadaro uri mukufambiswa kwe "mwaranzi inopisa". Pamusoro pechubhu yesilicon carbide inopisirwa kusvika pakupisa inoramba ichiburitsa mafungu emwaranzi ye infrared kunze. Mwenje wechiedza uyu usingaonekwe unogona kupinda mumhepo woshanda zvakananga pachinhu chinopisirwa, zvakafanana nenzira iyo chiedza chezuva chinodziisa nayo pasi. Kufambiswa kwekupisa kunopenya kunodzivirira kurasikirwa kwepakati, kunovandudza zvakanyanya kushanda kwekupisa kana tichienzanisa nekupisa kwe convective kwakajairika, uye kunoita kuti tembiricha igoverwe zvakaenzana.
3, Budiriro ye crystallization mune zvesainzi yezvinhu
Kusarudzwa kwesilicon carbide (SiC), rudzi rutsva rwezvinhu zveceramic, kunogona kuonekwa sekupedzisa. Kudzivirira kwayo kupisa kwakanyanya kunoita kuti pombi ishande nguva dzose pa1350 ℃, uye simba rayo rakapetwa kakawanda kupfuura simbi yakajairika; Chimiro chekristaro chakasiyana chinounza kudzivirira kupisa kwakanyanya, kunyangwe mushure mekutonhora nekudziya kamwe kamwe, hachizotsemuke; Chinewo hunhu hwekudzivirira ngura uye chinogona kubata mamiriro akasiyana-siyana ekunze anoparadza zviri nyore. Hunhu uhwu pamwe chete hunoumba hwaro hwehupenyu hwenguva refu hwechishandiso.
Nekuwedzera kuri kuita kudiwa kwekugadzirwa kwakachena, machubhu emurazvo esilicon carbide ari kutsiva machubhu ekupisa esimbi echinyakare zvishoma nezvishoma uye ari kuva sarudzo itsva yekuvandudza michina yekupisa yeindasitiri. Dhizaini yayo itsva ye "kudziyisa nekutamisa simba remwaranzi" inoderedza zvakanyanya mari yekugadzirisa uku ichivandudza kushanda zvakanaka kwesimba, ichipa rutsigiro rwehunyanzvi rwakavimbika rwekushandura indasitiri yekugadzira. Iyi hunyanzvi hwemaindasitiri hunobatanidza zvakakwana hunhu hwezvinhu nemisimboti yekufambisa kupisa iri kutsanangura patsva mwero weindasitiri wekudziyisa kupisa kwakanyanya.
