Huānga Whakamahana SiC
Ngā tokotoko silicon carbide (SiC), e mōhiotia ana ko ngā huānga whakamahana silicon carbide, he huānga whakamahana kore-whakarewa mahi-teitei, i hangaia mai i te SiC hexagonal matomato parakore-teitei mā te sintering pāmahana-teitei 2200℃. He ātete pāmahana teitei (tae atu ki te 1450℃), he tere whakamahana, he roa te ora mahi, me te tāutanga ngāwari, he pai mō ngā oumu ahumahi pāmahana-teitei me ngā taputapu pūtaiao.
Ngā Tauira Matua me ngā Whakamahinga:
(1) Raupapa GD (Ngā Rakau Diametera Ōrite)
He hoahoa whānui ōrite, he hanganga māmā, he iti hoki te utu. He pai mō ngā oumu pouaka iti, ngā oumu whakakākahu i roto i ngā taiwhanga me ngā mahi whakaputa iti. Ngā āhuatanga noa: Φ8–Φ40mm, te roa 200–2000mm.
(2) Raupapa CD (Ngā Rākau Matatoru)
Ka whakaitihia te ngaronga wera e ngā pito matao whānui ake, ka nui ake te pai o te whakamahana me te roa o te ora. He tino pai mō ngā oumu kauhanga nui, ngā oumu roera me ngā oumu whakarewa i roto i ngā ahumahi uku, karāhe. Ngā āhuatanga noa: wāhanga whakamahana Φ8–Φ30mm, pito matotoru Φ20–Φ60mm.
(3) Raupapa U (Ngā tokotoko āhua-U)
He āhua-U piko hei tāuta tika i runga i te whakairi, hei penapena wāhi mō te oumu. He whānuitia te whakamahinga i roto i ngā oumu korehau kiato me ngā taputapu whakawera uku.
(4) Ngā Rākau Āhua Ritenga
He tokotoko miro momo-W, momo puāwai paramu, kua whakaritea mō ngā hanganga oumu motuhake me ngā whakaritenga whakamahana.
Ātete pāmahana teitei:I roto i te āhuarangi waikura, ka taea e te pāmahana mahi noa te eke ki te 1450℃, ā, ka taea te whakamahi tonu mō te 2000 hāora.
Ātete pai rawa atu ki te waikura:Ina whakamahanatia ki te hau maroke i ngā pāmahana tiketike, ka hangaia he paparanga tiaki o te hauhā hiko (SiO₂) ki te mata o te tokotoko karāhe hiko, e whakarato ana i te ātete kaha ki te waikura.
Te pumau matū pai:He kaha tōna ātete ki te waikawa. Heoi, ka waikurahia e ngā matū kawakore i ngā pāmahana tiketike.
Te tere whakamahana tere:Kei a ia ngā āhuatanga o te whakamahana tere, ka taea ai te whakaara tere i te pāmahana o te mea kua wera ki te taumata e hiahiatia ana, ka whakapai ake i te pai o te whakaputa.
Te roa o te ora ratonga:Mā te whakamahinga tika me te tiaki, ka roa te ora o ngā tokotoko silicon carbide, ka whakaiti i te auau o ngā utu whakakapinga me te tiaki.
Te tāutanga me te tiaki ngāwari:He māmā te hanganga, ā, he watea hoki te tāuta me te tiaki. Ka taea hoki te hono atu ki tētahi pūnaha whakahaere hiko aunoa hei whakatutuki i te whakahaere pāmahana tika.

Ouma hiko ahumahi me te oumu hiko whakamātautau:He maha ngā wā ka whakamahia ngā tokotoko waro silicon i roto i ngā oumu hiko ahumahi pāmahana-waenga me te pāmahana-teitei, me ngā oumu hiko whakamātautau. He iti te utu, ā, he pai mō ngā mara ahumahi pāmahana-teitei pērā i te uku, te karāhe, me ngā rauemi ātete-wera.
Ahumahi karaihe:He whānuitia te whakamahinga o ngā tokotoko waro silicon i roto i ngā tāke karāhe pōrewa, ngā oumu rewa karāhe whatu, me te tukatuka hohonu karāhe.
Te whakarewa me ngā rauemi ātete-wera:I roto i te mahi whakarewa paura, te whatukawa whenua onge, te hikohiko, ngā rauemi aukume, te whakarewanga tika me ētahi atu ahumahi, he maha ngā wā ka whakamahia ngā tokotoko waro silicon i roto i ngā oumu pereti pana, ngā oumu whitiki mata, ngā oumu trolley, ngā oumu pouaka me ētahi atu huānga whakamahana.
Ētahi atu mara pāmahana teitei:Ka whakamahia hoki ngā tokotoko waro silicon i roto i ngā oumu kauhanga, ngā oumu roera, ngā oumu korehau, ngā oumu whakamahana, ngā oumu whakarewa me ngā taputapu whakamahana rerekē, e tika ana mō ngā wā e hiahiatia ana te whakahaere tika i te pāmahana.
