Pepa Parahi Parakore Tino Pai – He Arataki Wera Pai Rawa
Ataata
Pereti Parahi Kore-Hāora / ETP (C10100 / C10200 / C11000) – Tāpiritanga Hangarau
He tohunga mātou ki te hanga pereti parahi kounga teitei mō ngā kiritaki nui i roto i ngā rāngai hiko me te hiko, te whakahaere wera, te pūngao hou, me ngā taputapu papai. Awhe matotoru: 0.8–200 mm; whānui mōrahi: 2000 mm.
Tukanga Hanga Matua
● Rauemi mata: Ko te parahi hiko kounga teitei anake (≥99.97% Cu) mai i ngā kaihanga whakapaipai o te whare; ko ngā poke kino (Bi, Pb, S, P) e tino whakahaeretia ana i raro i te 10 ppm.
● Te whakarewa me te maka: Te maka tonu whakapae me te maka tonu-haurua hei whakarite i te hanganga ōrite o te kōpaka me te kore porowhita o roto i ngā pereti taumaha.
● Hurihuri wera: Hurihuri wera whakaiti-taumaha maha-haerenga i te 850–900 °C mō te āhua pereti tino pai (papatahi ≤3 mm/m).
● Te hurihuri makariri me te whakamahana: Te hurihuri makariri tino tika me te whakamahana pere tiaki-hauora kia kore ai he waikura, he kiri karaka rānei.
● Whakaoti: Kutikuti rere, mira mata-rua, whakataurite totoro-piko, tapahi wai-rere/reera. E wātea ana te ātete ā-ahu ±0.05 mm me te taratara o te mata Ra ≤0.4 μm mēnā ka tonoa.
Ngā Kaupapa Matua o te Mana Kounga
● Te whai i ngā puranga katoa: Ka rongoatia tonutia ngā wera katoa, ngā whakarewatanga katoa, me ngā pereti kua oti.
● Manatoko tuatoru: Ka whakamatautauria ia rota e SGS, BV, e te National Analysis Center for Iron & Steel / Nonferrous Metals rānei i mua i te tuku. Ka tukuna ngā pūrongo whakamātautau katoa (te hanganga matū, te kawe hiko, te rahi o te witi, te kounga o te mata) me te tuku.
● Te mahi tuturu (te toharite mō ngā marama 12):
1. Te kawe hiko: 101.0–102.5% IACS (C10200)
2. Te roa: ≥38% (te ātete H02)
3. Rahi o te witi: 0.015–0.035 mm
4. Te nui o te hāora: ≤3 ppm (C10100)
● Kāore e aro ki ngā hapa Akomanga-A (te pūwero o roto, ngā whakaurunga, te wehewehe, ngā kapiti) — ka whakakorea 100% ngā puranga kua pāngia.
Kāore mātou e whakataetae mō te utu iti rawa; e whakataetae ana mātou mō te auau teitei rawa atu o ia puranga me te roa o te ora ratonga. Tena koa, tohaina mai ō tuhi, ō whakaritenga hangarau rānei, ā, ka tukuna atu e mātou he tono tukanga me he tauira kua whakaritea mōu i roto i ngā rā mahi e toru.
