He whānuitia te whakamahinga o te nikara kuporo (te konukōre parahi-nikara) i roto i ngā mara moana, hiko, me ngā mara ahumahi. He tokomaha e whakaaro ana mēnā he uara tūturu tōna.
He tino mārama te whakautu: Āe. Nā tōna huinga ahurei o ngā āhuatanga, kāore e taea te whakakapi i roto i ngā āhuatanga tono nui. Kei raro nei he whakamārama taipitopito o tōna uara, āna tono, me ā mātou hua waea nikara parahi mahi teitei.
1. Uara Matua oNikara KapuroMahi Kāore i te ōrite
1.1 Ātete Pai ki te Waikura
He tino pai ki te ātete ki te waikura o te wai moana, te poke koiora, me te horo.
Ka hanga i tētahi kiriata waikura tiaki matotoru e ārai ana i te waikura o ngā poka me ngā kapiti, ka nui ake te pai o te mahi i ngā koranu noa i roto i ngā taiao moana.
Mā tēnei āhuatanga ahurei ka roa ake te ora o te taputapu i ngā konganuku noa, e 2-3 ngā wā ka roa ake, ka tino whakaiti i ngā utu tiaki.
1.2 Ngā Āhuatanga Hiko Pūmau
Te tauwehenga ātete pāmahana iti (te nuinga o te wā ko te 0.00001/°C).
Ka mau tonu te kawe hiko pumau ahakoa ngā piki me ngā heke o te pāmahana (-50°C ki te 400°C).
Nā tēnei he mea tino pai mō ngā wāhanga hiko tino tika pērā i ngā pūoko motuka me ngā pūnaha whakahaere ahumahi.
1.3 Te Āhuatanga Taurite o te Āhuatanga Mīhini
Ka whakakotahi i te kaha kume teitei (300-500 MPa) me te ngāwari tino pai.
He māmā te hanga hei waea, paipa, me ngā rau mā te tuhi, te piko, me te whakarewa.
Kāore te hanga e whakararu i te mahi matua, e urutau ana ki ngā hiahia hanga kanorau.
2. Ngā Tohu Noa me ngā Āhuatanga Matua o te Nikara Kuporo
He rerekē ngā momo nikara kapuro, ā, he rerekē ngā āhuatanga mō ngā whakamahinga motuhake. Kei te ripanga i raro nei ngā momo tino noa:
| Tau | Ōwehenga Parahi-Nikara | Ngā Āhuatanga Matua | Ngā tono noa |
| 90/10 | 90% Cu, 10% Ni | He ātete pai ki te waikura, he ngawari teitei | Ngā paipa moana, ngā whakawhiti wera |
| 80/20 | 80% Kū, 20% Ni | He ātete nui ki te wai moana, he kaha ake | Ngā papaaho moana, ngā waea hiko moana |
| 70/30 | 70% Cu, 30% Ni | He ātete tino pai ki te wai moana tere-rahi | Ngā poroporo kaipuke, ngā taputapu tango tote |
E whakaatu ana te ripanga e whai ake nei i te kaha whakataetae o te nikara cupro ki te maitai kore waikura me te parahi parakore:
| Tawhā Mahi | Nikara Kapuro | Kowiri tira (316) | Parahi Parakore |
| Ātete ki te Waikura o te Moana | Tino pai | Pai | rawakore |
| Tauwehenga Pāmahana o te Ātete | Iti (te kawe hiko pumau) | Waenga | Teitei (te kawe hiko e rerekē ana) |
| Te Pāmahana Whakahaere Tonu Mōrahi | 300-500°C | 870°C | 250°C |
| Te Whai Hua o te Utu (Wā Roa) | Teitei (iti te tiaki) | Waenga | Iti (ngāwari ki te waikura) |
3. Ngā Whakatakotoranga Matua: Te Wāhi e Hiranga ai te Nikara Cupro
3.1 Te Hangarau Moana
Whakamahia ana mō ngā paipa kaipuke, ngā whakawhiti wera, ngā wāhanga papaaho tai moana, me ngā waea hiko moana.
Mā tā mātou waea parahi nikara ka taea te whakarite kia pono te tuku tohu i roto i ngā taiao moana kino.
Ka whakarei ake hoki i te ātete ki te waikura, ka whakaiti i ngā reiti rahunga o ngā taputapu i roto i ngā mahi moana.
3.2 Te Hiko me te Hikohiko
Whakamahia ki ngā ātete tika, ngā taura whakamahana, ngā ine taumahatanga, me ngā pūoko motuka.
Mā te ātete pumau o tā mātou waea ka tika te mahi.
He mea tino nui tēnei tika mō ngā taputapu hiko e hiahia ana kia rite te putanga tohu.
3.3 Hauora me te Akuaku
E whakamahia ana hei "rauemi pā" i roto i ngā hōhipera nā te mea he āhuatanga patu huakita, e whakaiti ana i ngā tūponotanga whakawhiti-parahanga.
3.4 Te Moni me te Whakapaipai
E whakamahia ana mō ngā moni hiriwa (hei tauira, ngā moni ūropi) me ngā wāhanga whakapaipai, nā te mea he ātaahua, he pakari hoki.
4. Tō Mātou Waea Parahi Nikara: Te Whakanui i te Uara Rauemi
4.1 Ngā Whakatakotoranga Katoa
E kapi ana i ngā māka noa (90/10, 80/20, 70/30).
Kei waenga i te 0.06mm ki te 5.0mm te whānui o ngā waea.
E tautoko ana i ngā waea tahanga me ngā waea whakamahana, e tika ana mō ngā tono kanorau.
4.2 Ngā Otinga Whakarite
E whakarato ana i ngā waea kua paea, kua pūpū rānei hei whakapai ake i te ngāwari.
E tuku ana i ngā hanganga koranu ritenga hei whakatutuki i ngā whakaritenga waikura, pāmahana rānei.
E wātea ana ngā otinga tākai kua whakaritea mō ngā ota nui, iti rānei.
4.3 Te Mana Kounga Tino Pai
E tutuki ana i ngā paerewa o te ao ASTM B162, EN 1652, me ētahi atu paerewa o te ao.
Whakamātautau mahi 100% i mua i te tukunga, tae atu ki te ātete ki te waikura me te arowhai kawe hiko.
Ka whakahaerehia hoki ngā whakamātautau ātete diameter hei whakarite i te kounga me te pono tonu.
5. Whakamutunga: Te Uara Kāore e Taea te Whakakahore a Cupro Nickel
Nā te ātete ahurei o te nikara Cupro ki te waikura, te pumau hiko, me te maha o ngā whakamahinga, he mea tino whai hua tēnei i roto i ngā ahumahi nui.
Tā mātou waea parahi nikaraka whakamāoritia anō hoki tēnei uara rauemi hei otinga whai hua mō ngā mara moana, hiko, me te hauora.
Mena kei te rapu koe i ngā rauemi pono mō ngā taiao uaua, tino tika rānei, he haumitanga pai tā mātou waea parahi nikara. Whakapā mai ki a mātou mō ngā taunakitanga whaiaro me te tautoko hangarau.
