Ngā Ngongo Parahi i te Tau 2026: Ngā Kōtaha Porowhita, Tapawhā, me te Āhua Motuhake – Ngā Painga ki te Parahi Parakore

  I roto i ngā tono e hiahia ana kia taurite te kaha ā-mīhini, te ngāwari o te miihini, me te whai huatanga o te utu,ngā ngongo parahi(ko te nuinga ko te parahi kātere C26000/C27000, ko te parahi admiralty C44300 rānei) kua whakaū i tō rātou tūranga hei whakakapi pai mō te parahi parakore. I te mea e whakatairanga ana ngā ahumahi i ngā wāhanga pakari, ātete-waikura mō ngā mahi paipa, ngā taputapu, me ngā whakamahinga hoahoa, ka tukuna e ngā ngongo parahi he pai ake te mahi me te ātete ki te kakahu me te pupuri tonu i ngā āhuatanga wera me te hiko pai. I te tau 2026, me te pikinga o ngā utu rauemi me te aro nui ki te hanga pumau, ka haere tonu te hiranga o ngā ngongo parahi i te wāhi e whakawhāitihia ana e te ngawari o te parahi parakore me te utu teitei ake tōna pai.

E kapi ana tēnei tuhinga i ngā momo matua e toru o ngā ngongo parahi—he porowhita, he tapawhā, me ngā āhua motuhake (he rerekē te āhua)—ō rātou mahi, ngā ahumahi matua, ngā painga matua i ngā ngongo parahi parakore, me ngā horopaki e noho tonu ai te parahi hei whiringa nui.

He ngongo parahi, he porowhita, he tapawhā, he āhua motuhake hoki, e whakamahia whānuitia ana i roto i ngā mahi hangarau, whakapaipai, me ngā mahi putorino.

Ngā Momo Matua o ngā Ngongo Parahi me ā rātou Mahi Motuhake

Ko ngā ngongo parahi he mea whakaputa, he mea kumea rānei, he mea whakarewa/whakapiripiri e tutuki ana i ngā paerewa pēnei i te ASTM B135, EN 12451, me te JIS H3300, me te whakanui ake i te kaha me te āhua o te konutea:

1. Ngongo Porowhita TikaNgā ngongo porotaka paerewa i roto i ngā ngongo kumea mārō, i whakamahanatia rānei. He tino pai mō te whakawhiti wai, te whakawhiti wera, me ngā tautoko hanganga nā te matotoru o te pakitara me te ātete pēhanga.
2. Ngā Ngongo TapawhāHe kōtaha tapawhā, tapawhā rānei kua whakapūtātia, e whakarato ana i te kaha hurihuri teitei ake, me ngā mata papatahi ataahua. He pai mō ngā reera hoahoa, ngā anga, me ngā wāhanga tāonga.
3. Ngā Ngongo Āhua Motuhake (Heterotype)Ngā kōtaha kua whakapūtātia ritenga (porowhita, hexagonal, āhua-D, me ētahi atu) mō ngā whakaritenga whakauru motuhake. Whakahohehia te whakaurunga ara kī ki roto i ngā raka, te rere pai rānei ki roto i ngā pūwhakapūtā.

Ko ēnei puka, tae atu ki ā mātoungā ngongo parahi porowhita, ngā ngongo parahi tapawhā, mengā kōtaha parahi āhua motuhake, tautoko i te tikaMīhini CNCmō ngā huihuinga uaua.

Ngā Ahumahi Matua e Whakamahi ana i ngā Ngongo Parahi

He mea nui ngā ngongo parahi i roto i ngā rāngai e whakanui ana i te pakari me te ataahua:

• Ngā Paipa me ngā Taputapu Hauora→ Ngā takirere, ngā pūwero, me ngā hononga.
• Ngā Taonga Puoro→ Ngā tetere, ngā toropona, me ngā saxophone mō ngā āhuatanga oro.
• Ngā Whakawhiti Wera me ngā Waka→ Ngā pūwhakamatao hinu, ngā whakamatao hinu, me ngā pūwhakamātao (te parahi o te admiralty hei ārai i te waikura).
• Hanga Whare me te Whakapaipai→ Ngā ringaringa, ngā anga tāonga, me ngā rama.
• Ngā Raka me ngā Taputapu→ Ngā tinana rango me ngā wāhanga haumaru e hiahia ana kia ngāwari te miihini.
• Moana me te Ahumahi→ Ngā paipa wai moana me te hangarau whānui.

Ngā Painga i ngā Ngongo Parahi Parakore, me te Kore e taea te Whakakapi

He rerekē ngā painga o ngā ngongo parahi ki te parahi parakore (C11000/C12200):

• Te Kaha Mīhini Teitei Ake→ Kaha kume 300–500 MPa vs 200–250 MPa o te parahi; he pai ake te ātete ki te whakarerekētanga me te kakahu.
• Te Āheinga Mīhini Pai Rawa→ He pai te hanganga maramara me te whakaotinga mata i te wā e huri ana/keri ana; ka whakaiti i ngā utu taputapu.
• Te Ātete Waikura Whakarei Ake→ He pai ake te ātete o te parahi parakore o te moana ki te tango i te konutea me te whakaekenga o te wai moana i te parahi parakore i roto i ētahi taiao.
• Te Whai Hua o te Utu→ He iti ake te utu o ngā rauemi nā te whakakotahitanga o te konutea; he rite tonu te kawe wera (~150–200 W/m·K) mō ngā tono maha.
• Ataahua→ He tae koura tūturu me te pupuri oro mō ngā mahi whakapaipai.

He aha e kore ai e taea te whakakapi i te parahi e te parahi parakoreI roto i ngā taiao hanganga, miihini, whakakoi rānei, ka tere te pakaru, te whakakorikori, me te whakarerekē i te āhua o te parahi parakore i raro i te kawenga nā te mea he uaua te parahi. E 20–40% te utu nui ake o te parahi parakore, ā, he kino te mahi a ngā mīhini nā te mea he pīataata. Mō ngā raka, ngā taputapu, me ngā hononga e hiahia ana ki te miro tika, ki ngā manawanui piri, ki te pupuri āhua mō te wā roa rānei, ka tukuna e te parahi te pono me te ōhanga e kore e taea e te parahi parakore te rite me te kore he raruraru hoahoa nui.
