Ka taea te whakarāpopoto i te pānga o te whakahaere pāmahana i te wā o te tukanga whakakāwhata ki te mahi a te irahiko ki ngā kaupapa matua e whai ake nei:
1. Ka pā tika te mana whakahaere pāmahana ki te tohu whakapūkara me te hanganga karaihe
Te Whakapai Ake i te Tohu Whakapūmau: Me nui ngā pāmahana e hiahiatia ana mō te tukanga whakapūmau (mai i te 2500°C ki te 3000°C), ā, i taua wā ka whakarite anō ngā ngota waro mā te wiri wera hei hanga i tētahi hanganga paparanga pūmau. Ko te tika o te whakahaere pāmahana e pā tika ana ki te tohu whakapūmau:
- Pāmahana Iti (<2000°C): Ko te nuinga o ngā ngota waro e noho pūmau ana i roto i tētahi hanganga paparanga koretake, ka hua ake he iti te taumata whakakāwhata. Ka hua ake tēnei i te korenga o te kawe hiko, te kawe wera, me te kaha ā-pūkaha o te irahiko.
- Te Mahana Teitei (neke atu i te 2500°C): Ka tino whakarerekētia ngā ngota waro, ka piki ake te rahi o ngā tioata moroiti o te karāhe, ka whakaitihia hoki te tawhiti i waenga i ngā paparanga. Ka tino pai ake te hanganga tioata, ā, ka whakarei ake i te kawe hiko o te irahiko, te pumau matū, me te roa o te huringa.
Te Arotau i ngā Tawhā Karaihe: E whakaatu ana ngā rangahau, ina neke atu te pāmahana whakakāwhata i te 2200°C, ka pumau ake te papatahi pūmanawa o te kōka ngira, ā, he hononga nui te roa o te papatahi ki te pikinga o te rahi o te karaihe moroiti, e kī ana ko ngā pāmahana teitei ka whakatairanga i te raupapatanga o te hanganga karaihe.
2. Ka pā te Mana Whakahaere Pāmahana ki te Ihirangi me te Parakore o te Parakore
Te Tango i te Parakore: I te wā whakamahana tino whakahaeretia i ngā pāmahana i waenga i te 1250°C me te 1800°C, ka puta ngā huānga kore-waro (pērā i te hauwai me te hāora) hei hau, i te mea ka pirau ngā warowaihā taumaha-iti me ngā rōpū parakore, ka whakaiti i te nui o te parakore i roto i te irahiko.
Te Whakahaere i te Tere Whakamahana: Mena he tere rawa te tere whakamahana, ka mau pea ngā hau e puta mai ana i te pirau o te poke, ka puta he hapa o roto o te hiko. I tetahi atu taha, ka piki ake te whakapaunga pūngao ina puhoi te tere whakamahana. I te nuinga o te wā, me whakahaere te tere whakamahana i waenga i te 30°C/h me te 50°C/h hei whakataurite i te tango poke me te whakahaere i te ahotea wera.
Te Whakapai Ake i te Parakore: I ngā pāmahana teitei, ka pirau ngā warowaihā (pērā i te warowaihā silicon) hei kohu whakarewa me te karāpeti, ka whakaiti ake i te nui o te poke me te whakapai ake i te parakore o te hiko. Mā tēnei ka whakaitihia ngā tauhohenga taha i te wā o ngā huringa utu-tukunga, ā, ka roa ake te ora o te pākahiko.
3. Te Whakahaere Pāmahana me te Hanganga Moroiti o te Irahiko me ngā Āhuatanga Mata
Hanganga Moroiti: Ka pā te pāmahana whakakāwhata ki te āhua o te matūriki me te pānga here o te hiko. Hei tauira, ko te kōka ngira hinu e tukatukahia ana i ngā pāmahana i waenga i te 2000°C me te 3000°C kāore e whakaatu i te whakahekenga o te mata matūriki, ā, he pai te mahi here, ka hanga he hanganga matūriki tuarua pumau. Ka whakanui ake tēnei i ngā hongere whakauru lithium-ion, ā, ka whakarei ake i te kiato pono me te kiato tap o te hiko.
Ngā Āhuatanga o te Mata: Mā te maimoatanga pāmahana teitei ka whakaitihia ngā hapa o te mata o te hiko, ka whakaitihia te horahanga mata motuhake. Mā tēnei ka whakaitihia te pirau o ngā hiko me te tipu nui o te kiriata waenga-wāhanga hiko totoka (SEI), ka whakaitihia te ātete ā-roto o te pākahiko me te whakapai ake i te whai huatanga o te tukunga-utu.
4. Ka Whakahaerehia e te Mana Pāmahana te Mahi Hikohiko o ngā Irahiko
Te Āhuatanga Rokiroki o te Ritiumu: Ka pā te pāmahana whakapūkara ki te mokowā me te rahi o ngā tioata moroiti o te karapiti, ā, ka whakahaere i te whanonga whakauru/whakakore whakauru o ngā katote karapiti. Hei tauira, ko te ngira kōka i tukatukahia i te 2500°C he papa pūmau ake te kaha me te kaha rokiroki karapiti teitei ake, e tohu ana ka whakatairangahia e ngā pāmahana teitei te tino pai o te hanganga tioata karapiti me te whakarei ake i te mahi hikohiko o te irahiko.
Te Pūmautanga Huringa: Ka whakaitihia e te whakakāwhata pāmahana teitei ngā panonitanga rōrahi i roto i te hikohiko i ngā huringa utu-tukunga, ka whakaitihia te ngenge ahotea, ā, ka ārai i te hanganga me te horapa o ngā kapiti, ka roa ake ai te ora o te huringa o te pākahiko. E whakaatu ana ngā rangahau ina piki ake te pāmahana whakakāwhata mai i te 1500°C ki te 2500°C, ka piki ake te mātotoru tūturu o te kāwhata hangai mai i te 2.15 g/cm³ ki te 2.23 g/cm³, ā, ka tino pai ake te pumau o te huringa.
5. Te Whakahaere Pāmahana me te Pūmautanga me te Haumarutanga o te Hikohiko
Te Pūmautanga Wera: Mā te whakakāwhata pāmahana teitei ka whakarei ake i te ātete waikura me te pumau wera o te irahiko. Hei tauira, ahakoa ko te rohe pāmahana waikura o ngā irahiko kāwhata i te hau he 450°C, ka noho pūmau tonu ngā irahiko i tukuna ki te maimoatanga pāmahana teitei i ngā pāmahana teitei ake, ka whakaiti i te mōrearea o te rerenga wera.
Haumaru: Mā te arotau i te whakahaere pāmahana, ka taea te whakaiti i te kukū ahotea wera o roto i te hiko, ka ārai i te hanganga kapiti, ā, ka whakaiti i ngā tūponotanga haumaru i roto i ngā pākahiko i raro i ngā āhuatanga pāmahana teitei, utu nui rawa rānei.
Ngā Rautaki Whakahaere Pāmahana i roto i ngā Whakamahinga Whaihua
Te Whakamahana Maha-Wāhanga: Mā te whakamahi i tētahi huarahi whakamahana ā-wāhanga (pēnei i te whakamahana-mua, te whakawaro, me ngā wāhanga whakakāwhatu), me ngā tere whakamahana rerekē me ngā pāmahana ūnga kua whakaritea mō ia wāhanga, ka āwhina i te taurite o te tango poke, te tipu tioata, me te whakahaere ahotea wera.
Whakahaere Āhuarangi: Mā te whakahaere i te whakakāwhata i roto i te hau kore mahi (pērā i te hauota, te argon rānei) te hau whakaiti rānei (pērā i te hauwai) ka ārai i te waikura o ngā rauemi waro, me te whakatairanga hoki i te whakaritenga anō o ngā ngota waro me te hanganga o te hanganga kāwhata.
Te Whakahaere i te Tere Whakamatao: Kia oti te whakakāwhata, me āta whakamatao te hiko kia kore ai e pakaru, e rerekē rānei ngā rauemi i puta mai i ngā huringa ohorere o te pāmahana, kia mau ai te pono me te pumau o te mahi a te hiko.
