I-sintered silicon carbide sisixhobo esibalulekileyo se-ceramic, esisetyenziswa kakhulu kwiindawo ezinobushushu obuphezulu, uxinzelelo oluphezulu kunye namandla aphezulu. Ukusasazwa kwe-reaction ye-sic linyathelo eliphambili ekulungiseleleni izixhobo ze-SIC ezisasazwayo. Ulawulo olufanelekileyo lwe-sintered silicon carbide reaction lunokusinceda silawule ngcono iimeko zokusabela kwaye siphucule umgangatho wemveliso.
1. Ukuphucula imeko ye-silicon carbide ebangela ukurhawuzelelwa kwe-reaction
Iimeko zokusabela zizinto ezibalulekileyo kwiiparameter zempendulo ye-sintered silicon carbide, kubandakanya ubushushu bokusabela, uxinzelelo lokusabela, umlinganiselo wobunzima be-reactant kunye nexesha lokuphendula. Xa kulungiselelwa iimeko zokusabela, kuyimfuneko ukulungelelanisa ngokweemfuno ezithile zesicelo kunye nendlela yokusabela.
(1) Ubushushu bokusabela: Ubushushu bokusabela yenye yezinto eziphambili ezichaphazela isantya sokusabela kunye nomgangatho wemveliso. Ngaphakathi koluhlu oluthile, okukhona ubushushu bokusabela buphezulu, kokukhona isantya sokusabela sikhawuleza kwaye umgangatho wemveliso uphezulu. Nangona kunjalo, ubushushu bokusabela obuphezulu kakhulu buya kukhokelela ekwandeni kweembobo kunye nemingxunya kwimveliso, nto leyo echaphazela umgangatho wemveliso.
(2) Uxinzelelo lokusabela: Uxinzelelo lokusabela lukwachaphazela isantya sokusabela kunye noxinano lwemveliso. Ngaphakathi koluhlu oluthile, kokukhona uxinzelelo lokusabela luphezulu, kokukhona isantya sokusabela sikhawuleza kwaye uxinano lwemveliso luphezulu. Nangona kunjalo, uxinzelelo lokusabela oluphezulu kakhulu lunokukhokelela ekwandeni kweembobo kunye nemingxunya kwimveliso.
(3) Umlinganiselo wobunzima be-Reactant: Umlinganiselo wobunzima be-reactant yenye into ebalulekileyo echaphazela isantya se-reaction kunye nomgangatho wemveliso. Xa umlinganiselo wobunzima be-carbon kwi-silicon ufanelekile, izinga le-reaction kunye nomgangatho wemveliso. Ukuba umlinganiselo wobunzima be-reactant awufanelekanga, uya kuchaphazela isantya se-reaction kunye nomgangatho wemveliso.
(4) Ixesha lokuphendula: Ixesha lokuphendula lelinye lawona manqaku achaphazela isantya sokuphendula kunye nomgangatho wemveliso. Ngaphakathi koluhlu oluthile, kokukhona ixesha lokuphendula lide, kokukhona isantya sokuphendula sicotha kwaye umgangatho wemveliso uphezulu. Nangona kunjalo, ixesha elide kakhulu lokuphendula liya kukhokelela ekwandeni kweembobo kunye nemingxunya kwimveliso, nto leyo echaphazela umgangatho wemveliso.
2. Ulawulo lwenkqubo ye-silicon carbide etshintshayo
Kwinkqubo yokusabela kwi-sintered silicon carbide, kuyimfuneko ukulawula inkqubo yokusabela. Injongo yokulawula kukuqinisekisa ukuba impendulo izinzile kwaye umgangatho wemveliso uyahambelana. Ulawulo lwenkqubo yokusabela luquka ulawulo lobushushu, ulawulo loxinzelelo, ulawulo lomoya kunye nolawulo lomgangatho we-reactant.
(1) Ulawulo lobushushu: Ulawulo lobushushu yenye yezona zinto zibalulekileyo zolawulo lwenkqubo yokusabela. Ulawulo lobushushu Ubushushu bokusabela kufuneka bulawulwe ngokuchanekileyo kangangoko ukuqinisekisa inkqubo yokusabela ezinzileyo kunye nomgangatho wemveliso ohambelanayo. Kwimveliso yanamhlanje, inkqubo yolawulo lwekhompyutha idla ngokusetyenziswa ukulawula ngokuchanekileyo ubushushu bokusabela.
(2) Ulawulo loxinzelelo: Ulawulo loxinzelelo lolunye umba obalulekileyo wolawulo lwenkqubo yokusabela. Ngokulawula uxinzelelo lokusabela, uzinzo lwenkqubo yokusabela kunye nokuhambelana komgangatho wemveliso kunokuqinisekiswa. Kwimveliso yanamhlanje, inkqubo yolawulo lwekhompyutha idla ngokusetyenziswa ukulawula ngokuchanekileyo uxinzelelo lokusabela.
(3) Ulawulo lwemozulu: Ulawulo lwemozulu lubhekisa ekusebenziseni umoya othile (njengomoya ongasebenziyo) kwinkqubo yokusabela ukulawula inkqubo yokusabela. Ngokulawula umoya, kunokwenzeka ukuqinisekisa uzinzo lwenkqubo yokusabela kunye nokungaguquguquki komgangatho wemveliso. Kwimveliso yanamhlanje, umoya uhlala ulawulwa yinkqubo yolawulo lwekhompyutha.
(4) Ulawulo lomgangatho weReactant: Ulawulo lomgangatho weReactant yenye yezinto ezibalulekileyo ukuqinisekisa uzinzo lwenkqubo yereactant kunye nokuhambelana komgangatho wemveliso. Ngokulawula umgangatho wereactants, uzinzo lwenkqubo yereactant kunye nokuhambelana komgangatho wemveliso kunokuqinisekiswa. Kwimveliso yanamhlanje, inkqubo yolawulo lwekhompyutha idla ngokusetyenziswa ukulawula umgangatho wereactants.
Ulawulo olufanelekileyo lwe-reaction-sintered silicon carbide linyathelo eliphambili lokulungiselela izixhobo ze-silicon carbide ezikumgangatho ophezulu. Ngokwenza ngcono iimeko zokusabela, ukulawula inkqubo yokusabela kunye nokujonga iimveliso zokusabela, uzinzo lwenkqubo yokusabela kunye nokuhambelana komgangatho wemveliso kunokuqinisekiswa. Kwizicelo ezisebenzayo, impendulo ye-silicon carbide e-sintered kufuneka ilungiswe ngokweemeko ezithile zokusetyenziswa ukuze kuhlangatyezwane neemfuno ezahlukeneyo zokusetyenziswa.
