Kupu Whakataki: Ngā Para Karāpiti — Ngā Wāhanga Hira mō te Hanganga i te Pāmahana Tino Teitei
I roto i te ao o te hangahanga kounga teitei o ēnei rā, he maha ngā tukanga nui e whakawhirinaki ana ki ngā taiao e tohuhia ana e te wera nui. Mai i te whakarewa whakarewa tuku iho ki te hanga rauemi haurua-whakatipuranga tuatoru, ko ngā rauemi e whakamahia ana i roto i ngā taputapu pāmahana teitei me tu atu ki ngā taiao wera e tae atu ana ki ngā mano nekehanga Celsius engari me pupuri tonu hoki i ngā āhuatanga ā-tinana pumau, ngā kaha whakawhiti wera pai rawa atu, me te iti rawa o te mōrearea o te poke.
Ngā oko whakarewa karāpitii puta mai hei akomanga matua o ngā wāhanga pāmahana-tiketike hei whakatutuki i ēnei hiahia ahumahi.
I ngā wā o mua, ko ngā oko whakarewa i whakamahia hei pupuri me te whakawhiti i ngā rauemi rewa i te wā e whakarewahia ana ngā konganuku pēnei i te koura, te hiriwa, te parahi, me te konumohe. Heoi, nā te tere o te whanaketanga o ngā rāngai hanga matatau—tae atu ki te umanga haurua-ira, ngā hikohiko mana-tiketike, me ngā rauemi pūngao hou—kua whānui ake ngā whakamahinga o ngā oko whakarewa i tua atu i te mahi whakarewa tuku iho.
I ēnei rā, kua noho ngā oko whakarewa karapiti tino-parakore hei wāhanga nui o:
- Te tipu o te tioata kotahi SiC;
- Te hanga karaihe haurua-arataki;
- Te whakarite rauemi silicon photovoltaic;
- Maimoatanga wera korehau pāmahana teitei;
- Ngā pūnaha papa wera mō ngā taputapu CVD me te epitaxy.
I roto i te hanga haurua-ira, ehara i te mea he ipu pāmahana teitei noa iho te oko karāhe; he rauemi nui hoki i roto i te pūnaha papa wera, me ngā āhuatanga mahi e pā tika ana ki te kounga tioata, te ōritetanga pāmahana, me te pumau o te tukanga.
He aha te Para Karāpiti?
A oko paraihehe wāhanga pupuri pāmahana teitei i hangaia mai i te karāpeti parakore-teitei; e whakamahia ana hei pupuri, hei whakamahana, hei tukatuka rānei i ngā rauemi maha i roto i ngā taiao pāmahana tino nui.
Nā ngā āhuatanga motuhake o te karāpeti ki te wera, te hiko, me te matū, ka taea e ēnei oko whakarewa te mahi pumau i roto i ngā taiao e kore ai e rahua ngā rauemi whakarewa tuku iho.
I tēnei wā, e whakamahia whānuitia ana ngā oko whakarewa karāhe i roto i:
- Te whakarewa i te konganuku utu nui;
- Te whakarewatanga o te konganuku kore-ferrous;
- Te tukatuka koranu;
- Ngā whakamātautau taiwhanga pāmahana teitei;
- Te tipu o te tioata haurua-arataki;
- Te hanga rauemi pūngao hou.
I roto i te ao hangahanga teitei, ko te uara matua o ngā ipu karāpeti kei roto i tōna kaha ki te whakarato i tētahi taiao pāmahana teitei pumau, ma, me te tino ōrite. Hei tauira, i te wā e tipu ana te tioata silicon carbide (SiC), me mahi ngā ipu karāpeti mō ngā wā roa i roto i ngā taiao pāmahana teitei neke atu i te 2,000°C me te whakarite kia:
- Te whakawhiti wera ōrite;
- Te tipu o te karaihe pumau;
- Te iti rawa o te poke.
Nō reira, kua noho te karāpiti tino parakore hei rauemi matua e kore e taea te whakarerekē.

He aha te pai o te karāpiti mō ngā whakamahinga pāmahana teitei?
Ko te tūnga o te karāpiti hei rauemi nui i roto i ngā ahumahi pāmahana teitei i ahu mai i tōna hanganga rauemi ahurei.
He mea tito mai i ngā ngota waro kua whakaritea i roto i tētahi hanganga tioata paparua, he tino pai ngā āhuatanga wera me te pumau matū o te karapiti.
Tuatahi, he tino pai te ātete o te karāpiti ki te pāmahana teitei. I roto i ngā hau korehau, i ngā hau kore mahi rānei, ka taea e te karāpiti tino-parakore te tu atu ki ngā pāmahana tino nui mō ngā wā roa, me te pupuri tonu i te hanganga pai. Nā tēnei he tino pai mō ngā tukanga pāmahana tino-tiketike, pērā i te tipu tioata haurua-ira.
Tuarua, he tino pai te kawe wera o te karāpeti. He mea nui te whakahaere pāmahana e pā ana ki te kounga o te hua i te wā e hangaia ana te tioata. Ka taea e ngā piki me ngā heke o te pāmahana ā-rohe te arahi ki:
- Te pikinga ake o ngā hapa karaihe;
- Te whakaputanga ahotea;
- Ngā āhuatanga rauemi kua heke.
Mā te kawe wera pai rawa atu o te karāpiti ka āwhina i ngā taputapu kia tutuki ai te tohatoha āpure wera ōrite ake, ā, ka whakarei ake i te ōritetanga o te tukanga.
Hei tāpiritanga, he iti te tauwehenga whānui o te karāpeti, ā, he tino ātete ki ngā ru wera. He maha ngā wā ka tere te whakamahana me te whakamatao i roto i te hanga pāmahana teitei; ka whakaitihia e te karāpeti ngā kino hanganga i puta mai i te ahotea wera, ka roa ake te roa o te ora o ngā wāhanga.
I taua wā anō, he tino pai te pumau o te matū o te karāpeti parakore. I roto i ngā taiao hangahanga haurua-ira, he mea nui te poke o ngā rauemi e pā ana ki te hua o te hua. Mā te whakaiti i te nui o te poke me te arotau i te hanganga o ngā rauemi, ka whakaitihia e te karāpeti parakore te poke o ngā tukanga, ā, ka whakarei ake i te parakore o te tioata.
Te Tukanga Hanga o ngā Paraihe Karāhe Parakore-Teitei
Ehara i te mea he hua noa iho o te tukatuka ngāwari ngā oko whakarewa karāhe mahi-teitei; ka hangaia mā te whakarite rauemi pakari, te maimoatanga pāmahana teitei, me te miihini tika.
Ko te tukanga hangahanga ka tīmata mā te kōwhiringa o ngā rauemi mata o te karāhe parakore-teitei.
Ko ēnei rauemi mata ko te petroleum coke, te pitch coke, me ētahi atu rauemi waro parakore teitei. Mō ngā tono semiconductor, me tino whakahaere i:
- Te parakore o te waro;
- Te nui o te poke o te konganuku;
- Rahi o te witi;
- Te matotoru o ngā rauemi.
I muri i te kuru, te huri, me te tātari i ngā rauemi mata, ka konatunatua ki te mea here, kātahi ka hangaia hei hanganga para tuatahi.
Mō ngā tono haurua-ā-ira teitei, e whakamahia whānuitia ana te hangarau pēhi isostatic nā te mea ka puta he kiato rauemi ōrite ake, he pumau hoki ngā āhuatanga hangarau.
Ka tunua te para kua hangaia hei whakapakari i te kaha o te rauemi, hei whakau hoki i tōna hanganga o roto.
Muri iho, ka hurihia e te tukanga whakakāwhata te hanganga waro koretake hei hanganga tioata kāwhata tino raupapa i raro i ngā pāmahana tino tiketike.
Mā tēnei tukanga ka whakatauhia te hua whakamutunga:
- Te kawe wera;
- Ātete hiko;
- Te kaha o te miihini;
- Te pumau o te pāmahana teitei.
Hei whakamutunga, i runga i ngā whakaritenga tono motuhake, ka pāngia te oko graphite e:
- Te miihini tika CNC;
- Te maimoatanga mata;
- Te tirotiro i ngā āhuatanga;
- Maimoatanga horoi/whakapūmau.
Mā ēnei mahi ka tutuki i te para ngā whakaritenga tino tika me te tino pono o ngā taputapu haurua-ira.
