He aha tonu te tikanga o te tukanga "whakairoiro"?

"Te Whakairoiro"

Ko te "whakapūtanga kōwhai" e pā ana ki tētahi tukanga maimoatanga wera pāmahana teitei (e whakahaerehia ana i te 2000°C ki te 3000°C, neke atu rānei) e whakarerekē ana i te hanganga moroiti o ngā rauemi waro (pērā i te kōka hinu, te uku tāra waro, te waro anthracite, me ētahi atu) mai i te āhua koretake, iti rānei te raupapa ki tētahi hanganga tioata paparanga e rite ana ki te kōwhai tūturu. Ko te uho o tēnei tukanga kei roto i te whakaritenga taketake o ngā ngota waro, e whakawhiwhi ana i te rauemi ki ngā āhuatanga ā-tinana me te matū ahurei e āhua ana ki te kōwhai.

Te Tukanga Taipitopito me te Tikanga o te Whakairoiro

Ngā Wāhanga Maimoatanga Wera

1. Rohe Pāmahana-Iti (<1000°C)
   • Ka memeha haere ngā wāhanga pūngāwerewere (hei tauira, te makuku, ngā hauwaiwai māmā), ā, ka tīmata te hanganga ki te whakawhāiti mārire. Heoi anō, ka noho tonu ngā ngota waro he koretake, he poto rānei te tawhiti.
2. Rohe Pāmahana-Waenga (1000–2000°C)
   • Ka tīmata te whakarerekē i ngā ngota waro mā te nekehanga wera, ka hanga he hanganga whatunga hexagonal kua whakaritea ā-rohe (he rite ki te hanganga papa-roto o te karāpeti). Heoi, kei te noho pōrearea tonu te whakaritenga o waenga-papa.
3. Rohe Pāmahana-Tiketike (>2000°C)
   • I raro i te roanga o te wā e pāngia ana e te pāmahana teitei, ka āta whakarara haere ngā paparanga waro tetahi ki tetahi, ka hanga he hanganga tioata raupapa-toru-ahu (hanganga karāpiti). Ka ngoikore ngā kaha o ngā paparanga (ngā taunekeneke van der Waals), ka piki ake te kaha o te hononga hononga-ira-roto.

Ngā Huringa Hanganga Matua

• Te Whakarite Anō i te Ahu Waro: Te whakawhiti mai i tētahi hanganga "turbostatic" kore-āhua ki tētahi hanganga "paparanga" raupapa, me ngā ngota waro i roto i te papa e hanga ana i ngā hononga kovalent ranu sp² me te hononga paparanga mā ngā kaha van der Waals.
• Te Whakakore i te Hapa: Ka whakaitihia e ngā pāmahana teitei ngā hapa tioata (hei tauira, ngā takoto kau, ngā nekehanga), ka whakarei ake i te tioata me te pumau o te hanganga.

Ngā Whāinga Matua o te Whakairoiro

1. Te Whakarei Ahu Hiko
   • Ka hangaia e ngā ngota waro kua raupapahia he whatunga kawe hiko, ka taea ai te nekehanga kore utu irahiko i roto i ngā paparanga, ā, ka tino whakaitihia te ātete (hei tauira, ko te kōka hinu kua whakakāwhatatia he 10 ngā wā iti iho te ātete i ngā rauemi kāore i te whakakāwhatatia).
   • Ngā Whakamahinga: Ngā irahiko pākahiko, ngā paraihe waro, ngā wāhanga ahumahi hiko e hiahia ana ki te kawe hiko teitei.
2. Te Pūmautanga Wera Kua Whakapaitia
   • Ka ātete ngā hanganga kua whakaritea ki te waikura, ki te pirau rānei i ngā pāmahana teitei, ka whakarei ake i te ātete wera (hei tauira, ka tu atu ngā rauemi kua whakakāwhatia ki te >3000°C i roto i ngā āhuarangi kore mahi).
   • Ngā Whakamahinga: Ngā rauemi ātete ahi, ngā oko wera pāmahana-tiketike, ngā pūnaha tiaki wera o ngā waka mokowhiti.
3. Ngā Āhuatanga Mīhini kua Arotauhia
   • Ahakoa ka whakaitihia te kaha whānui e te whakakāwhata (hei tauira, te hekenga o te kaha pēhi), ka puta te anisotropy i te hanganga paparanga, ka mau tonu te kaha teitei i roto i te papa me te whakaiti i te pakarukaru.
   • Ngā Whakamahinga: Ngā irahiko karāpiti, ngā poraka katote tauine nui e hiahia ana ki te ātete ki te ru wera me te ātete ki te kakahu.
4. Te Pūmautanga Matū kua Whakanuia
   • Ka whakaitihia e te tioata teitei ngā pae hohe o te mata, ka whakahekehia te tere o te tauhohenga ki te hāora, ki ngā waikawa, ki ngā kawakore rānei, ā, ka whakanui ake i te ātete ki te waikura.
   • Ngā Whakamahinga: Ngā ipu matū, ngā arai hikohiko i roto i ngā taiao waikura.

Ngā Take e Pā Ana ki te Whakapūkara

1. Ngā Āhuatanga o ngā Rauemi Mata
   • Mā te nui ake o te ihirangi waro pumau ka māmā ake te whakakāwhata (hei tauira, he māmā ake te whakakāwhata o te petroleum coke i te tāra waro).
   • Ko ngā poke (hei tauira, te whanariki, te hauota) e ārai ana i te whakaritenga anō o ngā ngota, ā, me tukatuka i mua (hei tauira, te tango i te whanariki).
2. Ngā Tikanga Maimoatanga Wera
   • Pāmahana: Ka whakanui ake ngā pāmahana teitei i te taumata o te whakakāwhata engari ka piki ake ngā utu taputapu me te whakapaunga pūngao.
   • Wā: Ka pai ake te hanganga mēnā ka roa te pupuri, engari mā te roa rawa o te pupuri ka whakakiki te witi me te heke o te mahi.
   • Āhuarangi: Mā ngā taiao kore mahi (hei tauira, te argon) me ngā korehau ka ārai i te waikura me te whakatairanga i ngā tauhohenga whakakāwhata.
3. Ngā Tāpiri
   • Ka whakaitihia e ngā whakakorikori (hei tauira, te boron, te silicon) ngā pāmahana whakakoroiro me te whakapai ake i te whai huatanga (hei tauira, ka whakaitihia e te tāpiritanga boron ngā pāmahana e hiahiatia ana mā te ~500°C).

Te Whakataurite i ngā Rauemi Kua Whakairoirohia me ngā Rauemi Kāore i Whakairoirohia

Ngā Take Whakamahinga Whaihua

1. Ngā Irahiko Karāpiti
   • Ka whakakāwhatia te kōka hinu, te tāra waro rānei hei whakaputa i ngā irahiko kaha-teitei, he kaha-rahi te kawe hiko mō te hanga maitai o te oumu pewa hiko, e mau ana ki te >3000°C me ngā ia kaha.
2. Ngā Anode Pūhiko Lithium-Ion
   • Ko te karāpiti tūturu, hangai rānei (kua whakakārāpitihia) ka mahi hei rauemi anode, e whakamahi ana i tōna hanganga paparanga hei whakawhanui/whakakore i te katote lithium-ion tere, hei whakapai ake i te pai o te utu/tukunga.
3. Carburizer Hanga Rino
   • Mā te kōke hinu kua whakakākahuria, me tōna hanganga pūngoi me te nui o te waro, ka tere te whakanui ake i te nui o te waro i roto i te rino rewa, me te whakaiti i te whakaurunga o te poke whanariki.
