Ngongo tiaki silicon carbide

I roto i ngā ahumahi e mōrearea ana te kounga o ngā taputapu i ngā āhuatanga tino kino,ngā ngongo tiaki silicon carbide (SiC)Ka puta mai hei otinga hou. He rerekē ki ngā rauemi ārai tikanga, ka whakakotahi ngā ngongo SiC i te pūtaiao rauemi matatau me te hangarau pakari hei tiaki i ngā taputapu me ngā tukanga nui. Kei a ia ēnei painga e whai ake nei:

1. Te Parenga Kore-Whakataurite i roto i ngā Āhuatanga Whawhai

Ko ngā ngongo tiaki SiC hei rārangi tuatahi o te parepare i ngā taiao kāore e taea te rahunga:

（1）Te Parenga Wera: Ka taea te tu atu i ngā pāmahana roa tae atu ki te 1600°C, te tiaki i ngā pūoko, ngā takirua wera, ngā tirotiro rānei mai i ngā konganuku rewa, ngā mura, me te plasma.

（2）Ārai Matū: Ātete ki te waikura mai i ngā waikawa (hei tauira, te whanariki, te hauwaiora), ngā kawakore, me ngā hau tauhohe pēnei i te haurehu, te waikura whanariki rānei.

Ātete ki te Waro: Ārai i ngā matūriki horo i roto i ngā moenga wai, i ngā whakapūnga waro, i ngā mahi keri rānei.

2. Te Tika me te Pūmautanga mō ngā Inenga Tino Hira

I roto i ngā tukanga ahumahi nui te tūponotanga, he mea tino nui te tika. Ka whakarei ake ngā ngongo SiC i te pono mā te:

（1）Te Whakaiti i te Whakararuraru Tohu: Ka ārai ngā āhuatanga kore-arataki i ngā whakararuraru hikohiko i roto i ngā pūoko hiko.

（2）Te Pūmautanga o te Wera: Mā te āhua rerekētanga o te wera tata-kore ka whakarite kia ōrite te tūnga me te tika o te ine i raro i ngā huringa tere o te pāmahana.

（3）Te Ārai-Hau: Ka ārai te hanganga ā-roto i te urunga o te hau, he mea nui mō ngā pūnaha korehau, mō ngā hauhautanga whakahaeretia rānei.

3. Te Whakahohe i ngā Hangarau Whakatipuranga-E whai ake nei Ka wetewetehia e ngā ngongo tiaki SiC ngā auahatanga i roto i ngā mara hou:

（1）Te Ōhanga Hauwai: Hei hipoki pakari mō ngā pūoko i roto i te hanga hauwai, te rokiroki, me ngā pūtau wahie, e ātete ana ki te pakarukaru me te pānga ki te H₂ pēhanga teitei.

（2）Te Hanganga Ārahi: Te tiaki i ngā pūoko whatu me ngā pūoko wera i roto i ngā tauhohenga CVD (Te Whakatakotoranga Kohu Matū) mai i ngā matū waikura pēnei i te silane, te haukini rānei.

（3）Te Tūhuratanga Ātea: Te tiaki i ngā taputapu i roto i ngā miihini rōkete me ngā tirotiro aorangi mai i ngā pikinga wera nui me te irahiko ātea.

4. Te Whai Hua o te Utu mā te Roa o te Ora

Ahakoa he nui ake ngā utu o mua mō ngā ngongo SiC, ka huri anō te uara o ō rātou painga i te huringa ora:

（1）Te Whakaiti i te Wā Whakamutu: Ka roa ake te ora o ngā mea whakakapi mō te konganuku, te quartz rānei mā te 4–6 ngā wā i roto i ngā tautuhinga whakakoi, waikawa rānei, ka whakaiti i te tiaki kore i whakamaheretia.

（2）Kāore he Hiahia ki te Paninga: Kāore i rite ki ngā konganuku e hiahia ana ki ngā paninga tiaki, ka whakakorehia e ngā āhuatanga ā-roto o te SiC ngā utu maimoatanga mata auau.

（3）Whakamahinga anō: Ka ora tonu i ngā huringa tukanga maha i roto i ngā mahi pēnei i te whakarewa whakarewa, te hanga karāhe rānei, me te kore e pirau.

5. Whakaritenga mō ngā Hiahia Motuhake

Ka urutau ngā ngongo tiaki SiC ki ngā wero motuhake mā te hangarau kua whakaritea:

（1）Ngā Hoahoa Ranu: Whakauruhia ki ngā konganuku, ki ngā uku rānei mō ngā huihuinga maha-mahi (hei tauira, ngā hononga miro, ngā flange).

（2）Ngā Whakarerekētanga Mata: Ngā roto kua orohia mō ngā mahi whatu, ngā waho kua whakairohia rānei hei whakarei ake i te mararatanga wera.

（3）Ngāwari o te Rahi: I hangaia mai i ngā mirimita (ngā tauhohenga taiwhanga) ki ngā mita (ngā oumu ahumahi).

6. Te Whakahāngaitanga o te Oranga Tonutanga

Ka tautokohia e ngā ngongo SiC ngā mahi ahumahi e pai ana mō te taiao:

（1）Te Penapena Pūngao: Ka whakaitihia te whakapaunga wahie o te oumu e te pai o te wera tae atu ki te 20% ki te whakatauritea ki ngā parenga whakarewa.

（2）Te Whakaiti Para: Ka whakaitihia e te roa o te ora o te mahi ngā para rauemi mai i ngā whakakapinga maha.

（3）Whakaiti i te Paitini: Whakakorea te hiahia mō ngā paninga morearea (hei tauira, ngā koranu nikara) i roto i ngā taiao waikura.

Ko Shandong Zhongpeng Special Ceramics Co., Ltd tētahi o ngā otinga rauemi hou uku silicon carbide nui rawa atu i Haina. Uku hangarau SiC: Ko te pakeke o Moh he 9 (ko te pakeke o Moh hou he 13), he ātete pai ki te horo me te waikura, he ātete pai ki te pakū me te ārai-waikura. Ko te roa o te ora ratonga o te hua SiC he 4 ki te 5 ngā wā roa atu i te rauemi alumina 92%. Ko te MOR o RBSiC he 5 ki te 7 ngā wā i tō SNBSC, ka taea te whakamahi mō ngā āhua uaua ake. He tere te tukanga whakatau utu, ko te tuku e rite ana ki te mea i oatitia, ā, ko te kounga kāore he rite. Ka tohe tonu mātou ki te wero i ā mātou whāinga me te tuku i ō mātou ngākau ki te hapori.
