Ka pāngia te ātete waikura o ngā irahiko karāhe e te huinga o ngā āhuatanga, tae atu ki te pāmahana, te kukū hāora, te hanganga tioata, ngā āhuatanga rauemi irahiko (pēnei i te nekehanga karāhe, te kiato papatipu, me te kaha ā-ringa), te hoahoa irahiko (pēnei i te kounga hononga me te hototahitanga whānui wera), me te maimoatanga mata (pēnei i ngā paninga ārai-hauora). Anei tētahi tātaritanga taipitopito o ēnei āhuatanga:
1, Te pāmahana:
Ka tino piki ake te tere o te waikura o ngā irahiko karāpiti i te pikinga o te pāmahana. I runga ake i te 450°C, ka tīmata te kaha o te tauhohenga o te karāpiti ki te hāora, ā, ka tino piki ake te tere o te waikura ina neke ake te pāmahana i te 750°C.
I ngā pāmahana tiketike, ka kaha ake ngā tauhohenga matū i runga i te mata o te karāpeti, ka tere ake te waikura. Hei tauira, i roto i ngā oumu pewa hiko, ka neke ake te pāmahana o te mata o te irahiko i te 2000°C, ka waiho te waikura hei tino take o te paunga o te irahiko.
2, Te Kukū o te Hāora:
He mea nui te kukū o te hāora e pā ana ki te tere o te waikura o ngā irahiko karāpeti. I ngā pāmahana teitei, ka kaha ake te nekehanga wera o ngā ngota hāora, ka nui ake te tūponotanga ka tukinga rātou ki te karāpeti, ka whakatairanga i ngā tauhohenga waikura.
I roto i ngā taiao ahumahi pērā i ngā oumu pewa hiko, he nui te hau e tomo ana mā roto i ngā kōhao hiko o te taupoki oumu me ngā tatau oumu, ka kawe mai i te hāora, ā, ka whakanui ake i te waikura o ngā hiko.
3, Hanganga Kiriata:
He tino ngoikore te hanganga tioata o te karāpeti, ā, he ngāwari ki te whakaekehia e ngā ngota hāora. I ngā pāmahana teitei, ka rerekē te hanganga tioata o te karāpeti, ka heke te pumau me te tere o te waikura.
4, Ngā Āhuatanga o te Rauemi Irahiko:
- Teitei Whakakāwhata: Ko ngā irahiko he nui ake te kaha o te whakakāwhata he pai ake te ātete ki te waikura me te iti o te whakamahinga. Ko te kāwhata parakore teitei, me te pāmahana whakakāwhata e eke ana ki te 2800°C, e whakaatu ana i te ātete waikura pai ake i ngā irahiko kāwhata mana noa (me te pāmahana whakakāwhata tata ki te 2500°C).
- Te Matotoru o te Papatipu: Ka piki ake te kaha ā-pūkaha, te tauwehenga ngāwari, me te kawe wera o ngā irahiko karāpeti me te matotoru o te papatipu, ka heke te ātete me te porosity. He pānga tika tō te matotoru o te papatipu ki te whakamahinga o te irahiko, ā, ko ngā irahiko he matotoru nui ake te papatipu e whakaatu ana i te ātete waikura pai ake.
- Kaha Ā-Mīhini: Ehara i te mea ko te taumaha me ngā kaha o waho anake ngā irahiko karāpiti, engari ko ngā ahotea wera hoki o te taha whakarara, te taha tuaka, me te taha porohita i te wā e whakamahia ana. Ina nui ake ngā ahotea wera i te kaha ā-mīhini o te irahiko, ka pakaru pea, ka pakaru rānei. Nō reira, he kaha te ātete o ngā irahiko he kaha ā-mīhini teitei ki ngā ahotea wera, ā, he pai ake te ātete waikura.
5, Hoahoa Irahiko:
- Te Kounga o te Hononga: Ko ngā hononga ngā ngoikore o ngā irahiko, ā, he ngāwari ake te pakaru i te tinana o te irahiko. Ko ngā āhuatanga pēnei i te koretake o ngā hononga i waenga i ngā irahiko me ngā hononga, me te kore ōrite o ngā tauwehenga whānui wera, ka tere ake te waikura, ka whati hoki ngā hononga.
- Hototahi ki te Whānuitanga Wera: Ka taea hoki e ngā tauwehenga whānuitanga wera kore e ōrite i waenga i te rauemi hiko me te taiao e karapoti ana te hanga i te pakaru o te hiko. Ina pāngia te hiko e te whānuitanga wera i ngā pāmahana teitei, ki te kore e taea e te taiao e karapoti ana, e ngā rauemi rānei e pā ana ki te hiko te whānui, ka puta te kukū ahotea, ā, ka mutu, ka pakaru.
6, Te Maimoatanga Mata:
Mā te whakamahi i ngā paninga ārai mate ka taea te whakanui ake i te ātete waikura o ngā irahiko karāpeti. Hei tauira, ka hangaia e te paninga ārai mate karāpeti RLHY-305 he paninga ārai mate matotoru ki runga i te mata o te papa, e whakarato ana i ngā āhuatanga hiri pai rawa atu. Ka wehea te hāora mai i te karāpeti i ngā pāmahana teitei, ka aukati i te tauhohenga i waenga i te karāpeti me te hāora, ā, ka whakaroa ake i te roanga o te ora o ngā hua karāpeti mā te 30% neke atu rānei.
He tikanga ārai-waikura whai hua anō hoki te maimoatanga whakakī. Mā te whakakī i ngā ārai-waikura ki roto i ngā irahiko karāpiti mā te whakakī korehau, mā te rumaki taiao rānei, ka taea te whakapai ake i te ātete waikura o ngā irahiko.
