Isicelo
Iiceramics ze-silicon carbidesebenza indima ebalulekileyo kwimisebenzi yokutshisa i-industry kumacandelo amaninzi. Esona sicelo siphambili yi-silicon carbide burner nozzles, esetyenziswa ngokubanzi kwiinkqubo zokutsha ezinobushushu obuphezulu bokulungiswa kwesinyithi, ukuveliswa kweglasi, kunye nokudubula kwe-ceramic ngenxa yozinzo lwazo kwindawo ezishushu kakhulu. Olunye usetyenziso oluphambili yi-silicon carbide rollers, esebenza njengenkxaso kunye nokuhanjiswa kwezinto kwiikloni eziqhubekayo, ngakumbi ekufakweni kwee-ceramics eziphambili, izinto ze-elektroniki, kunye neglasi echanekileyo. Ukongeza, ii-ceramics ze-SiC zisetyenziswa njengezinto zolwakhiwo ezinje ngemiqadi, iireyile, kunye neeseta kwiziko leeko, apho zinyamezela ukuvezwa ixesha elide kwiatmosphere enobundlongondlongo kunye noxinzelelo lomatshini. Ukudityaniswa kwabo kwiiyunithi zokutshintsha ubushushu kwiinkqubo zokubuyisela ubushushu obusetyenzisiweyo kugxininisa ngakumbi ukuguquguquka kwazo kulawulo lwe-thermal olunxulumene ne-kiln. Ezi zicelo zigxininisa ukuguquguquka kwe-silicon carbide kwiimfuno ezahlukeneyo zokusebenza ngaphakathi kwetekhnoloji yokufudumeza kwemizi-mveliso.
Usetyenziso oluphambili lweziko lokushishina lubandakanya:
1.Imilomo ye-silicon carbide burner
3.Imiqadi ye-silicon ye-carbide
4.I-silicon carbide ityhubhu ekhanyayo
Izinto eziluncedo kwezobuGcisa
1. Uzinzo lweThermal oluKhethekileyo
-Indawo yokunyibilika: 2,730°C (igcina ubume bobushushu obuphezulu kakhulu)
- Ukumelana ne-oxidation ukuya kuthi ga kwi-1,600 ° C emoyeni (ithintela ukuthotywa kwe-oxidative atmospheres)
2. I-Superior Thermal Conductivity
- I-150 W/(m·K) i-thermal conductivity kwiqondo lobushushu begumbi (yenza ukuhanjiswa kobushushu ngokukhawuleza kunye nokuhanjiswa kobushushu obufanayo)
- Ukunciphisa ukusetyenziswa kwamandla nge-20-30% xa kuthelekiswa nezixhobo zendabuko ezichasayo.
3. Ukumelana neThermal Shock Resistance
- Ukumelana nokuguquguquka okukhawulezileyo kobushushu okudlula i-500°C/sec (ilungele ukufudumeza umjikelo/iinkqubo zokupholisa).
- Ukugcina ingqibelelo yesakhiwo phantsi kwebhayisikile ye-thermal (inqanda ukuqhekeka kunye nokuguqulwa).
4. Amandla oomatshini aphezulu kumaqondo obushushu anyusiweyo
- Igcina i-90% yamandla obushushu begumbi kwi-1,400 ° C (ibaluleke kakhulu kwiinxalenye ze-kiln ezithwala umthwalo).
- Ukuqina kwe-Mohs ye-9.5 (ukumelana nokunxiba kwizinto ezinqabileyo kwiindawo ze-kiln).
