Isicelo
I-selicon carbide ye-ceramicsKhonza iindima ezinobuchule kwimizi mveliso ye-rights kumacandelo amaninzi. Isicelo esiphambili sisiLicon Carner Buzzles, isetyenziswe ngokubanzi kwiinkqubo eziphezulu zokuhamba kwamaqondo okuhambisa, ukwenziwa kweglasi, kunye nokudubula kwe-ceramic ngenxa yeendawo ezigqithileyo zengqolowa. Olunye usetyenziso oluphambili yi-Silicon carbiders, nto leyo yenziwa njengenkxaso kunye nezinto ezidlulisela kwiikhilomitha eziqhubekayo, ngakumbi kwi-elektroniki, kunye neglasi efanelekileyo. Ukongeza, i-ceramics ye-SIC iqeshwa njengezixhobo zesakhiwo ezinjengeebhulethi, kunye neeseti ezikwimicebo yaseKiln, apho zinyamezelwa ixesha elide kwi-adges kunye noxinzelelo loomatshini. Ukudityaniswa kwabo kubushushu be-shacksurn ye-SUFRT yeNkqubo yokuBuyisa kobushushu obubuyisela umva kugxininisa kakhulu kulawulo lwe-kiln. Ezi zicelo zigxininisa ukuziqhelanisa ne-carbide ze-carbide kwiindawo ezahlukeneyo zokusebenza kwiitekhnoloji zokufudumeza imizi mveliso.
Izicelo eziphambili zeKineyment zeza eziPhambili zibandakanya:
1.I-Silicon Carbide Burner Nozzles
Izibonelelo zobugcisa
1. Uzinzo olukhethekileyo
- Inqaku lokunyibilika: I-2,730 ° C (ixhasa imeko yeqondo lobushushu)
-Ukuxhathisa i-oxidation ukuya kwi-1,600 ° C emoyeni (kuthintela ukonakaliswa kwe-oxidage)
I-2. Ukuqhubela phambili kwengqondo
I-150 w / (m · k) yokuqhubela phambili kwegumbi lokuphumla
Ukunciphisa ukusetyenziswa kwamandla nge-20-30% ngokuthelekiswa nezinto zemvelo zemveli.
I-3. Ukunganyangeki kothukile
-Ukuhlala ngokukhawuleza kwamaqondo obushushu obuguqukayo obungaphezulu kwe-500 ° C / sec (ilungele i-cyclic heating / iinkqubo zokupholisa).
-Gcina ingqibelelo yesakhiwo phantsi kwebhayisikile ye-thermal (uthintela ukuqhekeka kwaye ulahlekelwe).
4. Ukomelela okuphezulu kumaqondo obushushu aphakamileyo
-Igcina i-90% yamaqondo obushushu egumbi kwi-1,400 ° C (ibaluleke kakhulu ekutsaleni imithwalo yomthwalo).
- I-MOHS eluhlaza ye-9.5 (i-rester (i-chancis inxibe izinto ezingenanto).

Imeko yeShishini
Ishishini elikhokelayo le-Metional Grenterurgical lifezekisile ukuphuculwa okubonakalayo emva kokudibanisa i-selicon carbide (i-SIC) ye-ceramics kwiinkqubo zayo zeqondo eliphezulu. Ngokutshintsha izinto eziqhelekileyo ze-alumina kunyeI-Silicon Carbide Burner Nozzles, ishishini lixeliwe:
✅ Iipesenti ezingama-40 zokugcina izinto zolondolozo zonyaka eziphantsi zonyaka ngenxa yokuncitshiswa kwecandelo ngo-1500 ° 2 iindawo +.
I-20% yonyuso kwixesha lokuvelisa, iqhutywa kukunganyangeki kuka-sic kwi-shrick ye-shirmal kunye ne-sothres kwi-molten slag.
Ulungelelwaniso nemigangatho yolawulo lwe-IS 50001 yezamandla, ukuqhubela phambili i-SIC ephezulu yokuphucula ukusebenza kwe-opeel nge-15 ukuya kwi-20%.
