He aha te pāmahana ka taea e te paraikete muka uku te tu atu?

"He aha te pāmahana ka taea e te paraikete muka uku te tu atu?"
He pātai tēnei e tino whakamāmāhia ana, e kore rānei e māramahia i roto i ngā mahi hangarau. He whānuitia te whakamahinga o ngā paraikete muka uku i roto i ngā arai oumu ahumahi me ngā pūnaha whakamahana, engari ko te take matua ehara i te teitei o te pāmahana ka taea e rātou te tu atu mō te wā poto, engari mehemea ka mau tonu tā rātou mahi i roto i te wā roa.

Nō reira, kāore e taea te tautuhi i te ātete pāmahana o ngā paraikete muka uku mā te tau kotahi. I roto i te kōwhiringa hangarau, he mea nui kia wehewehea i waenga i ngā ariā pāmahana e toru e whai ake nei:

Te Pāmahana Whakarōpūtanga

Ko te pāmahana whakarōpūtanga e pā ana ki te pāmahana mōrahi e whakaatu ana te hua, i raro i ngā āhuatanga taiwhanga, i te whakahekenga rārangi kāore e neke ake i te rohe kua tohua i muri i te whakamātautau pāmahana teitei 24-hāora. Ka whakamahia tēnei pāmahana mō te whakarōpūtanga me te tautuhi hua, ā, kāore e tohu i te pāmahana ratonga roa e whakaaetia ana i roto i ngā tono tūturu.

Te Pāmahana Whakamahi Tonu

Ko te pāmahana whakamahinga tonu te tawhā tino nui mō te kōwhiringa hangarau. Koinei te pāmahana teitei rawa atu e taea ai e te hua te pupuri i te hanganga pumau me te mahi i raro i ngā āhuatanga mahi mō te wā roa. I te nuinga o te wā, ko te pāmahana whakamahinga tonu he iti iho i te pāmahana whakarōpūtanga tata ki te 150–200°C.

Te pāmahana whakawhāiti

Ko te pāmahana rohe ko te awhe e tīmata ai te muka ki te pakaru me te tere o te pirau. I tua atu i tēnei wā, ka tere te heke o te mahi a te rauemi. Kaua rawa tēnei pāmahana e whakamahia hei pūtake mō te hoahoa hangarau, mō te kōwhiringa rauemi rānei.

Ngā Mea e Pā Ana ki te Mahi Tūturu o te Pāmahana o ngā Paraikete Muka Uku

I raro i ngā āhuatanga mahi tūturu, ka pāngia te ātete pāmahana tuturu o ngā paraikete muka uku e ngā āhuatanga maha, tae atu ki te hanganga matū, te momo muka, me te pumau hanganga pāmahana teitei.

Te Awe o te Hanganga Matū me te Momo Muka

Ko te pāmahana o ngā paraikete muka uku ka whakatauhia e te ihirangi o te alumina (Al₂O₃), te silica (SiO₂), me te whakaurua o te zirconia (ZrO₂):

• Taumata S (1260°C / 2300°F)
  Te ihirangi konumohe ≥ 44%. E whakamahia whānuitia ana i roto i ngā tono whakamahana ahumahi paerewa.
  Te pāmahana whakamahinga tonu noa: tata ki te1050°C (1922°F).

• Taumata HPS (1260°C / 2300°F)
  He paraikete muka uku tino parakore, he iti iho i te 1% te nui o te poke, e pai ake ai te ātete ki te whakatioata me te pumau matū.
  Te pāmahana whakamahinga tonu noa: tata ki te1100°C (2012°F), e tika ana mō ngā tono he nui ake ngā whakaritenga mō te pumau mō te wā roa.

• Paraikete PUREWOOL RCF (1260°C / 2300°F, 1430°C / 2600°F)
  He mea hanga mai i ngā rauemi mata hangai parakore-teitei, he tino iti te poke, ā, he mā ake te āhua. I te taumata pāmahana kotahi, ka whakaratohia e PUREWOOL te ātete ki ngā ru wera me te mahi whakamarumaru pai ake.

• Taumata HZ (1430°C / 2600°F)
  I hangaia ki te 15% ZrO₂ pea, e whakarei ake ana i te pumau o te hanganga me te ātete ki te sintering i ngā pāmahana tiketike.
  Te pāmahana whakamahinga tonu noa: tae atu ki te1350°C (2462°F).

Ngā Awhe Pāmahana e Pā Ana mō ngā Pūnaha Muka Rerekē

• Raupapa Paraikete RCF
  Te mahi whai hua i roto i te awhe pāmahana tata ki te1000–1400°C, e tuku ana i tētahi huinga taurite o te mahi me te utu. Ko tēnei raupapa tētahi o ngā hua muka e whakamahia whānuitia ana i roto i ngā arai oumu ahumahi.

• Raupapa Paraikete PCW
  Me te pumau hanganga tino pai, ka taea e ngā paraikete PCW te pupuri i te mahi pono i roto i ngā āhuatanga pāmahana tino teitei e tata ana, e neke atu rānei1500°C (2732°F)He pai ēnei mō ngā rohe tino pāmahana teitei, mō ngā tono rānei e hiahia ana kia roa ake te ora mahi.

• Raupapa Paraikete LBP
  Te hipoki i ngā taumata pāmahana o1200°C (2192°F)me1300°C (2372°F), he mea hanga ngā paraikete LBP mō ngā whakamahinga pāmahana waenga ki te pāmahana teitei. Ka whakaratohia he mahi whakamātao pumau me te whai i ngā ture hauora mahi me te taiao pakari ake, ka waiho hei huarahi kē atu i te RCF i roto i ngā taiao haumaru me te aro ki ngā ture.

Kāore he whakautu kotahi mō te pātai whānui,"He aha te ātete pāmahana o te paraikete muka uku?"
I roto i te mahi hangarau, me hangai te kōwhiringa rauemi ki tepāmahana whakamahi tonuPonoparaikete muka ukuEhara te kōwhiringa i te mea ko te whiriwhiri i te pāmahana teitei rawa, engari ko te whiriwhiri i tētahi rauemi ka taea te pupuri i te mahi pumau mō te wā roa i raro i ngā āhuatanga whakahaere tuturu.
