I roto i te mara o te pāmahana teitei ahumahi, ko te whakatutukitanga o te whakawhiti wera haumaru me te whai hua ko te kī ki ngā putanga hangarau hou.Ngongo irahiko silicon carbideHe taputapu motuhake tēnei i hangaia mō ngā āhuatanga pāmahana teitei. He rite ki te "kaikawe pūngao wera" puku, ā, he mahi nui tōna i roto i te whakamahana i ngā oumu i roto i ngā ahumahi pēnei i te whakarewa, te miihini matū, me te uku. Kia wetewetehia te mea ngaro o tōna kaupapa mahi mā roto i ngā tirohanga matua e toru.
1, He ārai pakari hei tiaki i te uho
Ko ngā wāhanga matua o roto o te ngongo hihi silicon carbide kua takaihia marietia ki roto i tētahi ngongo o waho i hangaia ki te rauemi silicon carbide, hei hanga i tētahi parenga takirua: ko te ngongo silicon carbide o waho hei kawe hihi wera, hei ārai haumaru hoki, kia tino wehea ai ngā wāhanga whakamahana o roto mai i te taiao oumu. Ehara i te mea ka roa ake te ora o ngā ngongo hihi silicon carbide anake, engari ka tino whakaitihia hoki ngā utu tiaki.
2, Tikanga whakawhiti wera ahurei
He rerekē ki te kawe wera tuku iho, ko te painga matua o ēnei taputapu ko te whakawhiti i te "ira wera". Ka tukuna tonutia e te mata o te ngongo silicon carbide kua werahia ki te āhua incandescent ngā ngaru ira whero ki waho. Ka taea e tēnei ngaru mārama e kore e kitea te uru ki te hau, ka pā tika ki te mea kua werahia, he rite ki te whakamahana o te rā i te whenua. Ka karohia e te whakawhiti wera ira te ngaronga waenga, ka whakapai ake i te pai o te wera ki te whakataurite ki te whakamahana convective tuku iho, ā, ka hua ake he tohatoha pāmahana ōrite ake.
3, Te whakawhaititanga hou i roto i te pūtaiao rauemi
Ko te kōwhiringa o te silicon carbide (SiC), he momo rauemi uku hou, ka taea te kī ko te whakaotinga. Nā tōna ātete pāmahana teitei ka taea e te tinana paipa te mahi tonu i te 1350 ℃, ā, he maha ngā wā o tōna kaha i te maitai noa; Ko te hanganga karaihe ahurei e whakarato ana i te ātete wera pai rawa atu, ahakoa i muri i te whakamatao me te whakamahana ohorere, e kore e pakaru; He āhuatanga ātete-waikura anō hoki, ā, ka taea te whakahaere i ngā momo hau waikura ahumahi me te ngāwari. Ko ēnei āhuatanga ngātahi te turanga o te roa o te ora ratonga o te taputapu.
I te pikinga ake o te hiahia mō te hanga ma, kei te whakakapi haere ngā ngongo irahiko silicon carbide i ngā ngongo whakamahana whakarewa tuku iho, ā, kei te noho hei whiringa hou mō te whakapai ake i ngā taputapu wera ahumahi. Ko tana hoahoa auaha o te "whakamahana motuhake me te whakawhiti pūngao irahiko" ka tino whakaiti i ngā utu tiaki me te whakapai ake i te whai huatanga o te pūngao, ka whakarato tautoko hangarau pono mō te huringa matomato o te ahumahi hanga. Ko tēnei mahi toi ahumahi e tino whakauru ana i ngā āhuatanga rauemi me ngā mātāpono whakawhiti wera kei te tautuhi anō i te paerewa ahumahi mō te whakamahana pāmahana teitei.
