I-silicon carbide ye-Sintered yinto ebalulekileyo ye-ceramic, esetyenziswa ngokubanzi kubushushu obuphezulu, uxinzelelo oluphezulu kunye namasimi anamandla aphezulu. I-reaction sintering ye-sic linyathelo eliphambili ekulungiseleleni imathiriyeli ye-SIC edibeneyo. Olona lawulo lulungileyo lwe-sintered silicon carbide reaction lunokusinceda ukulawula iimeko zokusabela ngcono kunye nokuphucula umgangatho wemveliso.
1. Ukuphuculwa kweemeko zokusabela kwi-silicon carbide
Iimeko zokusabela ziyimilinganiselo ebalulekileyo ye-sintered silicon carbide reaction, kubandakanywa ubushushu bokusabela, uxinzelelo lokusabela, umlinganiselo we-reactant mass kunye nexesha lokuphendula. Xa ulungiselela iimeko zokusabela, kuyimfuneko ukulungelelanisa ngokweemfuno ezithile zesicelo kunye nendlela yokusabela.
(1) Ubushushu bokusabela: Ubushushu be-Rection yenye yezinto eziphambili ezichaphazela isantya sokusabela kunye nomgangatho wemveliso. Kuluhlu oluthile, kokukhona ubushushu bokusabela buphezulu, kokukhona isantya sokusabela sikhawuleza kwaye kokukhona umgangatho wemveliso uphezulu. Nangona kunjalo, iqondo lokushisa eliphezulu kakhulu liya kukhokelela ekwandeni kweepores kunye neentanda kwimveliso, echaphazela umgangatho wemveliso.
(2) Uxinzelelo lokuphendula: Uxinzelelo lokuphendula lunefuthe kwisantya sokusabela kunye nokuxinana kwemveliso. Ngaphakathi kuluhlu oluthile, ukuphakama koxinzelelo lokusabela, ngokukhawuleza isantya sokusabela kunye nokuphezulu koxinano lwemveliso. Nangona kunjalo, uxinzelelo oluphezulu kakhulu lokuphendula lunokukhokelela ekwandeni kwee-pores kunye nokuqhekeka kwimveliso.
(3) Reactant mass ratio: Reactant mass ratio yenye into ebalulekileyo echaphazela isantya reaction kunye nomgangatho wemveliso. Xa umlinganiselo wobunzima bekhabhoni kwisilicon ufanelekile, izinga lokusabela kunye nomgangatho wemveliso. Ukuba i-reactant mass ratio ayifanelekanga, iya kuchaphazela isantya sokusabela kunye nomgangatho wemveliso.
(4) Ixesha lokuphendula: Ixesha lokuphendula yenye yezinto ezichaphazela isantya sokusabela kunye nomgangatho wemveliso. Kuluhlu oluthile, ixesha lokusabela lide, isantya sokuphendula siyacotha kwaye umgangatho wemveliso uphezulu. Nangona kunjalo, ixesha elide lokuphendula liya kukhokelela ekwandeni kweepores kunye nokuqhekeka kwimveliso, echaphazela umgangatho wemveliso.
2. Ulawulo lwenkqubo ye-silicon carbide yokusabela-sintering
Kwinkqubo yokusabela ye-silicone carbide, kuyimfuneko ukulawula inkqubo yokusabela. Injongo yolawulo kukuqinisekisa ukuba ukusabela kuzinzile kwaye umgangatho wemveliso uyahambelana. Ulawulo lwenkqubo yokusabela lubandakanya ulawulo lobushushu, ulawulo loxinzelelo, ulawulo lwe-atmospheric kunye nolawulo lomgangatho wokusabela.
(1) Ulawulo lobushushu: Ulawulo lobushushu yenye yezinto ezibalulekileyo zolawulo lwenkqubo yokusabela. Ulawulo lobushushu Ubushushu bokusabela kufuneka ilawulwe ngokuchanekileyo kangangoko kunokwenzeka ukuze kuqinisekiswe inkqubo yokusabela ezinzileyo kunye nomgangatho wemveliso ongaguqukiyo. Kwimveliso yanamhlanje, inkqubo yolawulo lwekhompyuter idla ngokusetyenziswa ukulawula ngokuchanekileyo ubushushu bokusabela.
(2) Ulawulo loxinzelelo: Ulawulo loxinzelelo lolunye umba obalulekileyo wolawulo lwenkqubo yokusabela. Ngokulawula uxinzelelo lokusabela, ukuzinza kwenkqubo yokusabela kunye nokuhambelana komgangatho wemveliso kunokuqinisekiswa. Kwimveliso yanamhlanje, inkqubo yolawulo lwekhompyuter idla ngokusetyenziswa ukulawula ngokuchanekileyo uxinzelelo lokusabela.
(3) Ulawulo lwe-atmosphere: Ulawulo lwe-atmosphere lubhekisela ekusebenziseni umoya othile (njengomoya ongasebenziyo) kwinkqubo yokusabela ukulawula inkqubo yokusabela. Ngokulawula umoya, kunokwenzeka ukuqinisekisa ukuzinza kwenkqubo yokusabela kunye nokuhambelana komgangatho wemveliso. Kwimveliso yanamhlanje, umoya udla ngokulawulwa yinkqubo yekhompyutha.
(4) Ulawulo lomgangatho we-reactant: Ukulawulwa kwekhwalithi ye-reactant yenye yeenkalo ezibalulekileyo zokuqinisekisa ukuzinza kwenkqubo yokusabela kunye nokuhambelana komgangatho wemveliso. Ngokulawula umgangatho wee-reactants, ukuzinza kwenkqubo yokusabela kunye nokuhambelana komgangatho wemveliso kunokuqinisekiswa. Kwimveliso yanamhlanje, inkqubo yokulawula ikhompyuter idla ngokusetyenziswa ukulawula umgangatho we-reactants.
Ulawulo olufanelekileyo lwe-react-sintered silicon carbide linyathelo eliphambili lokulungiselela umgangatho ophezulu we-silicon carbide materials. Ngokulungisa iimeko zokusabela, ukulawula inkqubo yokusabela kunye nokubeka iliso kwimveliso yokusabela, ukuzinza kwenkqubo yokusabela kunye nokuhambelana komgangatho wemveliso kunokuqinisekiswa. Kwizicelo ezisebenzayo, i-sintered silicon carbide reaction ifuna ukulungiswa ngokweemeko ezithile zesicelo ukuhlangabezana neemfuno ezahlukeneyo zesicelo.
