Mu gawo la kutentha kwambiri kwa mafakitale, kukwaniritsa kusamutsa kutentha kotetezeka komanso kogwira mtima kwakhala chinsinsi cha kupita patsogolo kwaukadaulo.Chitoliro cha radiation cha silicon carbidendi chipangizo chapadera chomwe chapangidwira makamaka zochitika zotentha kwambiri. Chimagwira ntchito ngati "chonyamula mphamvu yotenthetsera" chete ndipo chimagwira ntchito yofunika kwambiri mu uvuni wotenthetsera m'mafakitale monga zitsulo, uinjiniya wa mankhwala, ndi zoumba. Tiyeni tivumbule chinsinsi cha mfundo yake yogwirira ntchito kudzera m'magawo atatu akuluakulu.
1, Chotchinga cholimba choteteza pakati
Zigawo zamkati mwa chubu cha radiation cha silicon carbide zimakulungidwa mosamala mu chubu chakunja chopangidwa ndi zinthu za silicon carbide, zomwe zimapangitsa chitetezo chambiri: chubu chakunja cha silicon carbide chimagwira ntchito ngati chonyamulira kutentha komanso chotchinga chitetezo, kuonetsetsa kuti zinthu zotenthetsera zamkati zimalekanitsidwa kwathunthu ndi malo ophikira ng'anjo. Sikuti zimangowonjezera nthawi ya moyo wa machubu a radiation a silicon carbide, komanso zimachepetsa kwambiri ndalama zokonzera.
2, Njira yapadera yosamutsira kutentha
Mosiyana ndi kutentha kwachikhalidwe, ubwino waukulu wa zipangizo zotere uli mu kusamutsa "kutentha kwa dzuwa". Pamwamba pa chubu cha silicon carbide chomwe chimatenthedwa mpaka kufika pa incandescent nthawi zonse chimatulutsa mafunde a infrared radiation kunja. Kuwala kosaoneka kumeneku kumatha kulowa mumlengalenga ndikugwira ntchito mwachindunji pa chinthu chotenthedwa, mofanana ndi momwe kuwala kwa dzuwa kumatenthetsera dziko lapansi. Kusamutsa kutentha kowala kumapewa kutayika kwapakati, kumawonjezera kwambiri mphamvu ya kutentha poyerekeza ndi kutentha kwachizolowezi, ndipo kumapangitsa kuti kutentha kugawikane mofanana.
3, Kupambana kwa crystallization mu sayansi ya zinthu
Kusankhidwa kwa silicon carbide (SiC), mtundu watsopano wa zinthu zadothi, kungawonedwe ngati kumaliza. Kukana kwake kutentha kwambiri kumalola thupi la chitoliro kugwira ntchito mosalekeza pa 1350 ℃, ndipo mphamvu yake ndi yochulukirapo kuposa ya chitsulo wamba; Kapangidwe kake kapadera ka kristalo kamabweretsa kukana kwabwino kwambiri kutentha, ngakhale atakumana ndi kuzizira mwadzidzidzi ndi kutentha, sikung'ambika; Ilinso ndi mphamvu zotsutsana ndi dzimbiri ndipo imatha kuthana ndi mlengalenga wosiyanasiyana wa mafakitale mosavuta. Makhalidwe awa pamodzi amapanga maziko a moyo wautali wa chipangizocho.
Chifukwa cha kufunikira kwakukulu kwa kupanga zinthu zoyera, machubu a radiation a silicon carbide pang'onopang'ono akulowa m'malo mwa machubu otenthetsera achitsulo achikhalidwe ndikukhala chisankho chatsopano chokweza zida zotenthetsera zamafakitale. Kapangidwe kake katsopano ka "kutenthetsera kosiyana ndi kusamutsa mphamvu ya radiation" kumachepetsa kwambiri ndalama zokonzera pomwe kumawonjezera kugwiritsa ntchito mphamvu moyenera, kupereka chithandizo chodalirika chaukadaulo pakusintha kobiriwira kwa makampani opanga zinthu. Zojambulajambula zamakampani izi zomwe zimagwirizanitsa bwino zinthu zakuthupi ndi mfundo zosamutsa kutentha zikusinthanso muyezo wamakampani wotenthetsera kutentha kwambiri.
