Ngā pūwero mura o te silicon carbide (SiC)

I roto i ngā tukanga pāmahana teitei, he mea nui te whakahaere wai, te ātete ki te horo, me te pumau o te wera,ngā pūwero karawiti silicon (SiC)he mea whakamiharo te hangarau. He rerekē ki ngā pūwero uku, whakarewa rānei, ko ngā āhuatanga ahurei o te SiC e aro ana ki ngā wero o te tahunga, te pana, me ngā pūnaha rehu ahumahi. Ka tūhuratia e tēnei tuhinga te take e piki haere ana te whakamahi a ngā ahumahi i ngā pūwero SiC hei huri i te mahi i roto i ngā tono tino uaua.

1. I hangaia mō ngā taiao wai tino nui

He tino pai ngā pūwero SiC ki te whakahaere i ngā wai me ngā hau tere-teitei, pāmahana-teitei:

（1）Ātete ki te Horo: Ka ātete ki ngā matūriki whakakoi i roto i ngā werohanga para waro, ngā pūnaha pupuhi onepu, ngā pūwero rōkete rānei, me te kore e puta he āhua rerekē nā te kakahu.

（2）Te Ora i te Ru Wera: Ka tere te huri i waenga i ngā pāmahana tino kino (hei tauira, te werohanga wahie i roto i ngā oumu whakarewa) me te kore e pakaru, nā te iti o te horapa wera o te SiC.

（3）Te Ātete Matū: Ātete ki te waikura mai i ngā rehu waikawa/kawakore, ngā tote rewa, ngā mura waikura rānei, kia rite ai te āhua o te kōhao.

2. Te Mana Rere Tika mō ngā Tukanga Tino Hira

I roto i ngā tono e hiahia ana kia tika te taumata-micron, ka tukuna e ngā pūwero SiC te pono e kore e taea te whakataurite:

（1）Te Āhua o te Kōhao Pūmau: Kia mau tonu te rere me ngā tauira rehu tika ahakoa te roa o te whakamahinga ki ngā taiao 1500°C+, he rerekē ki ngā konganuku e piko ana, ki ngā uku rānei e pirau ana.

（2）Te Whakaiti i te Ārai: Mā te āhua maeneene o te mata ka whakaitihia te kohikohinga rauemi i roto i ngā werohanga wahie, i ngā pūnaha rehu matū rānei.

（3）Ātete Pēhanga Teitei: Ka ātete ki ngā pēhanga waipēhi neke atu i te 500 MPa, he mea tino pai mō te tapahi i te waipēhi, mō te whakaterenga rererangi rānei.

3. Te Whakahohe i te Tahu Tino Pai

He mea nui ngā pūwero SiC ki te arotau i ngā pūnaha tahunga kaha-pūngao:

（1）Te Pūmautanga o te Mura: Mā te hoahoa ātete-wera ka ōrite te ranunga wahie-hau i roto i ngā tāhū hau, i ngā mura ahumahi rānei, ka whakaiti i ngā wera me ngā tukunga NOx.

（2）Ngāwari o te Wahie: Hototahi ki te hauwai, ki ngā wahie koiora, ki ngā hinu taumaha rānei, hei tautoko i te whakawhiti ki ngā pūtake pūngao pumau.

（3）Te Whai Hua o te Wera: Whakaitihia te ngaronga wera mā roto i ngā pakitara nā te kawe wera teitei o te SiC, ka whakapai ake i te whai huatanga o te rūma mura tae atu ki te 15%.

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.
