Ngā ngongo hihi silicon carbide

Ngā ngongo hihi silicon carbidehe wāhanga uku matatau e mōhiotia whānuitia ana mō tā rātou mahi tino pai i roto i ngā tono ahumahi pāmahana teitei me te waikura. Nā ō rātou āhuatanga rauemi ahurei me te urutau hanganga e mea nui ai rātou i roto i ngā taiao mahi uaua. Kei raro nei he tirohanga whānui mō ō rātou painga matua me ngā tono.

1. Ngā Āhuatanga Rauemi Pai Rawa

He rauemi uku mahi-teitei te SiC, ā, he tino pai ōna āhuatanga:

（1）Ātete ki te Pāmahana Tino Kaha: Ka taea te mahi tonu i ngā pāmahana tae atu ki te 1600°C me te wā poto neke atu i te 1800°C, he nui atu i ngā otinga whakarewa tuku iho.

（2）Te Awe Wera Teitei: Mā te kawe wera e 2–3 ngā wā teitei ake i ngā konganuku, ka taea e ngā ngongo hihi Silicon carbide te whakamahana tere me te tohatoha pāmahana ōrite.

（3）Te Whakawhanuitanga Wera Iti: Mā te iti o te whakawhānuitanga wera ka whakaitihia te ahotea i te wā o ngā piki me ngā heke o te pāmahana, kia mau ai te pumau o te hanganga.

（4）Ātete ki te Waikura me te Waikura: Ātete ki ngā waikawa, ki ngā kawakore, ki ngā konganuku rewa, me ngā hau kaha, ahakoa i raro i ngā āhuatanga pāmahana teitei mō te wā roa.

2. Te Āhuatanga Hanganga

Ka taea te whakarite i ngā ngongo hihi silicon carbide mō ngā hiahia ahumahi rerekē:

（1）Ngā Hoahoa Whakaritenga: Kei te wātea i roto i ngā whirihoranga torotika, āhua-U, āhua-W rānei hei whakapai ake i te tohatoha wera me te whakamahinga o te wāhi.

（2）Whakaurunga Pakari: Hototahi ki ngā pare whakarewa, ki ngā pūnaha hiri uku rānei mō ngā hononga ātete turuturu i roto i ngā whakatakotoranga uaua.

1. Ngā Painga Whakahaere

（1）Te Whai Hua o te Pūngao: Ka whakaitihia te whakapaunga pūngao e te kawe wera teitei mā te whakateretere i te whakawhiti wera.

（2）Te Ora Ratonga Roa: Ko ngā ngongo hihi silicon carbide e 3–5 ngā wā e roa ake ai i ngā momo konganuku kē atu i roto i ngā taiao uaua, ka whakaiti i te wā kore mahi me ngā utu whakakapinga.

（3）Ātete ki te Ru Wera: Ka ātete ki ngā huringa whakamahana me te whakamatao tere, me te kore e pakaru, he mea tino pai mō ngā tukanga e hiahia ana kia huri pinepine te pāmahana.

4. Ngā Whakamahinga Ahumahi Matua

He tino pai ngā ngongo hihi o te silicon carbide i roto i ngā rāngai matua:

（1）Te whakarewa: Whakamahia i roto i ngā oumu whakamahana, ngā oumu whakakā, me ngā pūnaha whakawera mō te maimoatanga wera ōrite.

（2）Te Tukatuka Matū: Hei ngongo tauhohenga, hei tautoko whakakorikori rānei i roto i ngā tauhohenga pāmahana-tiketike me ngā oumu whakakorikori.

（3）Te Hanga Uku/Karāhe: Kia tika te whakahaere i te pāmahana i roto i ngā oumu whakarewa me ngā oumu whakarewa karāhe.

（4）Ngā Pūnaha Taiao: Ka whakamahia i roto i ngā tahunga para me ngā wāhanga tukatuka hau hei whakahaere i ngā hau waikura i ngā pāmahana teitei.

5. Ngā Painga Whakataurite ki ngā Huarahi Rēwena:

6. He aha i whiriwhiri ai i ngā ngongo hihi Silicon carbide?

Ko ngā ngongo hihi silicon carbide te kōwhiringa tino pai mō ngā ahumahi e whakatairanga ana i:

（1）Te pumau o te pāmahana tino nui, engari kāore e heke te mahi.

（2）Te pono mō te wā roa i roto i ngā āhuarangi waikura, waikura rānei.

（3）He whakamahana ōrite, he penapena pūngao hoki, mō ngā tukanga e arohia ana e te tika.

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.
