Ina whakaaro tātou ki ngā rauemi hangarau teitei, ka peke atu tātou ki ngā koranu titanium, ki te muka waro, ki te maitai kore waikura kanapa rānei. Heoi, ko te poutokomanawa o tō tātou ao hou he tino iti ake:maitai waro noaE 85-90% pea o te hanga maitai o te ao te take o tēnei koranu, ā, koia te "hōiho mahi" o te ahumahi. Engari he aha rawa te mea e tino hira ai te maitai waro "ma", ā, he aha ngā pono taketake mō tōna āhua?
Te Māmā o te Koranu
Ko te kupu "maamaa" e tohu ana he iti noa ngā huānga whakarewa kei roto i tēnei maitai. Kāore i te nui te chromium, te nickel, te molybdenum rānei, e tāpirihia ana ki ngā maitai motuhake. Engari, he mea whakarewa rino me te waro te nuinga. He iti noa te manganese me te silicon, engari ko te waro te mea matua e whakahaere ana i ngā āhuatanga o te maitai.
Ko te pono tino nui mō te maitai waro noa ko te whanaungatanga whakahurihuri i waenga i te kaha me te ngāwari. I a koe e whakanui ana i te waro, ka pakeke haere te maitai, ka kaha ake, engari ka pakarukaru haere, ka uaua ake hoki te whakarewa.
He Whānuitanga o te Kaha
Ko te tikanga, ka whakarōpūhia e ngā miihini te maitai waro māori ki ngā rōpū e toru i runga i tō rātou "tohu" waro:
Rino Waro Iti (Rino Ngāwari):Kei roto i tēnei momo te waro tae atu ki te 0.25%, ā, koinei te momo tino noa. He maha ā mātou whakamahinga mō ngā panera tinana waka me ngā kurupae hanganga i roto i ngā whare teitei. Ā, he tino pai mō te hanganga nui me te hanga ngongo maitai. Ko tōna "pono" kei roto i tōna ngāwari whakamiharo; ka taea e koe te piko, te takai, me te whakarewa me te kore e whati.
Rino Waro Waenga:He taurite te hanganga o tēnei putanga, arā, 0.25% ki te 0.6% te waro. He kaha rawaka te rauemi mō ngā ara rerewē me ngā taputapu, e whakakotahi ana i te ātete ki te pakaru me te kaha ki te tu atu i te wiri nui me te kore e pakaru.
Te maitai waro teitei:I te nuinga o te wā kei roto i te 0.6% ki te 1.2–1.4% te waro, he tino mārō tēnei konganuku. Mā te whakamahi i te maitai waro teitei ka taea ai te whakamahi i ō maripi kīhini, i ngā mata wiri, me ngā puna. Ka roa ake te pupuri a te rauemi i te mata koi i te maitai ngawari. Me tika te whakamahana. Ki te kore he maimoatanga tika, ka tino heke te pakari o te pānga.
Te Tauhokohoko: Te Take Waikura
Ko tētahi o ngā pono tino kore e taea te karo mō te maitai waro noa ko tōna ngoikore ki te taiao. Ka hangaia e te maitai kore waikura he paparanga waikura chromium tiaki. Kāore te maitai waro noa e mahi pera, ā, ka tere te tauhohe ki te hāora me te makuku. Ki te kore he paninga tiaki—pērā i te peita, te hinu, te paparanga konutea rānei (whakarewa)—ka hoki anō ki tōna āhua tūturu: te waikura rino, te waikura rānei.
Mō ngā tono hanganga, ko tōna uara tūturu kei roto i:
- Whēkenga matapaetia
- Ngā māka paerewa
- Te hanga pai
- Te wātea o te ao whānui
Mai i ngā anga hanga whare ki ngā whatunga paipa rino, ko te rino waro noa te toa ngaro o te hangarau hanganga o ēnei rā.
He aha i toa tonu ai
He aha i whakamahia whānuitia ai te maitai waro noa, ahakoa te waikura, ā, he iti ake te pakari i ngā koranu tauhou? Ko te whakautu ko te ōhanga me te āheinga ki te hangarua. He iti ake te utu o te hanga maitai waro noa i tētahi atu konganuku he rite te kaha.
Hei whakaroa i te roa o te mahi, ka tiakina ngā paipa maitai hanganga e:
- Te peita, te paninga rānei
- Te whakahinuhinu mō te rokiroki rangitahi
- Te whakakikorua (paninga konutea) mō ngā taiao o waho me te makuku
Mā te tiaki tika i te mata, ka taea e ngā paipa maitai waro ma te mahi pono mō ngā tekau tau.
Hei tāpiritanga, ko tētahi o ngā rauemi hangarua rawa atu o te ao. Ka taea te whakarewa i tētahi kurupae maitai mai i tētahi whare putunga o ngā tau 1920, ā, ka taea te whakamahi anō hei anga waka o te tau 2026. Kāore anō kia rerekē te kounga.
Whakamutunga
E whakaatu ana te maitai waro noa kāore i te pai ake ngā rauemi uaua ake i ngā tono hangarau. Mā te panoni iti o te ihirangi waro i roto i te rino ka taea te whakaputa i tetahi mea mai i te waea ngohengohe ki ngā tautoko piriti nui. He rauemi e tautuhia ana e te taurite—te tauhokohoko i te ātete waikura mō te utu, me te ngāwari mō te kaha.
