Ngā rākau whakamahana porowhita silicon carbide (SiC), e mōhiotia ana ko ngā Huānga Whakamahana Spiral SiC, he wāhanga whakamahana kore-whakarewa matatau i hangaia mō ngā tono ahumahi pāmahana teitei rawa. Hei wāhanga matua o ngā oumu ahumahi me ngā pūnaha whakamahana, he pai ake ngā tokotoko whakamahana SiC porowhita i ngā whakamahana whakarewa tuku iho me tō rātou ātete wera pai rawa atu, te pumau o te waikura, me te roa o te ora ratonga, ka waiho hei whiringa matua mō ngā pakihi e rapu ana i ngā otinga whakamahana pāmahana teitei pono.
He rerekē ki ngā wāhanga whakamahana whakarewa e tere pakaru ana i roto i ngā taiao uaua, ka taea e ngā tokotoko whakamahana SiC porowhita te mahi pumau i ngā pāmahana mai i te 600°C ki te 1600°C, me te kawenga mata mōrahi o te 15–25 W/cm². Mā te hanganga porowhita ahurei o ēnei tokotoko ka whakarite kia rite te tohatoha wera, ka whakaiti i te rerekētanga pāmahana (i roto i te 40°C i te 1300°C) me te whakarite kia rite te kounga hua i roto i ngā tukanga wera nui—he painga matua mō ngā ahumahi e whakawhirinaki ana ki te whakamahana tika.
Ngā Painga Matua o ā Mātou Rakau Whakamahana SiC Porowhita
- Ātete ki te pāmahana tino teitei:He pumau te mahi tae atu ki te 1600°C, he pai mō te whakawera wera, te tukatuka wera, me ngā tukanga rewa — he pai mō ngā oumu ahumahi.
- Painga o te Hanganga Porowhita:Ka whakarei ake te rohe whakamahana porowhita i te pai o te wera, ka whakarite kia ōrite te tohatoha wera, ā, ka pupuri i te putanga hiko pumau, ka whakaiti i te whakapaunga pūngao.
- Te pakari tino pai:He mea hanga ki te SiC tino parakore (≥95%) me te iti o te porosity me te kaha o te ātete ki ngā ru wera, ka ātete ēnei tokotoko SiC porowhita ki te pakaru i ngā huringa whakamahana me te whakamatao tere.
- Ātete ki te Waikura me te Ātete ki te Waikura:He tino pumau te matū ki te waikura, ki ngā waikawa, me ngā kawakore, e mau tonu ana te mahi i roto i ngā āhuarangi oumu kino me te kore e poke i ngā hua.
- Ngāwari te Tāutanga me te Whakaritenga:Ka uru ngā inenga paerewa me ngā rahi ka taea te whakarite (te whānui, te roa, te ātete) ki ngā hoahoa oumu ahumahi, me ngā pito porowhita hei whakamau haumaru.
Ngā Whakatakotoranga Matua (Paerewa me te Whakaritenga)
Kua whakaritea ā mātou tokotoko whakamahana SiC porowhita kia tutuki ai ngā hiahia ahumahi kanorau, me ngā whakatakotoranga ngāwari:
- Te whānui:6mm–60mm (ka taea te whakarite ki te 80mm)
- Te Roa Katoa:100mm–1500mm (e wātea ana ngā roa ritenga)
- Te Roa o te Rohe Whakamahana:Ka taea te whakarite mō ia hoahoa oumu
- Te Roa o te Pito Matao:150mm–250mm (paerewa, ka taea te whakarite)
- Ātete me te Mana:Whakaritea kia rite ki ngā whakaritenga hiko
Ngā Taupānga Ahumahi e Whakamahia Whānuitia ana
He mea nui ngā tokotoko whakamahana SiC porowhita mō ngā ahumahi e hiahia ana ki te whakamahana pāmahana teitei tika, tae atu ki:
- Ngā Uku me ngā Pūwero Ātete:Te whakapūtanga o ngā uku matatau, ngā taonga oumu, me ngā hua ātete ahi
- Te Whakarewa me te Karāhe:Te whakamahana i te konganuku, te whakarewa paura, te rewa karāhe, me te tukatuka
- Ngā Hikohiko me ngā Pūnaha Whakahaere-ā-Haumaru:Te whakapūtanga o ngā wāhanga uku me te tukatuka muka whatu
- Niho me te Hauora:Te whakakoi tika o ngā whakatikatika niho zirconia
- Taiwhanga me te Rangahau:Ngā oumu whakakā, ngā oumu ngongo, me ngā taputapu whakamātautau pāmahana teitei
He aha i whiriwhiri ai mātou i ā mātou tokotoko whakamahana SiC porowhita? Ka piri mātou ki ngā paerewa whakaputa kua whakamanahia e ISO, me te whakahaere kounga tino pakari hei whakarite i te mahi pumau me te tika o ngā āhuatanga. Ka whakaratohia e tā mātou tīma he tautoko hangarau ngaio mō te tahora oumu, te tāutanga, me te whakaritenga - mai i te hoahoa hanganga porowhita ki te taurite ātete. Ka tukuna e mātou he tuku iti me te nui, hei āwhina i a koe ki te whakaiti i te auau whakakapinga me ngā utu whakaputa.
Mena kei te rapu koe i ngā tokotoko whakamahana SiC porowhita pono, mahi-teitei mō āu oumu ahumahi, whakapā mai ki a mātou i tēnei rā mō tētahi whakatau utu ritenga me te kōrero hangarau. Whakapai ake i tō pūnaha whakamahana me ā mātou huānga whakamahana silicon carbide porowhita pakari, whai hua.
