Kowiri tira ka taea te hangarua, ā, ka taea te pupuri tonu
Mai i tōna whakaurunga tuatahi i te tau 1915, kua whānuitia te whiriwhiri i te maitai kore waikura mō te whakamahi i roto i ngā momo ahumahi nā te mea he pai rawa ōna āhuatanga miihini me te waikura. Ināianei, i te mea e nui haere ana te aro ki te whiriwhiri i ngā rauemi pumau, kei te rongonui haere te maitai kore waikura nā ōna āhuatanga taiao pai rawa atu. Ka taea te hangarua 100% te maitai kore waikura, ā, i te nuinga o te wā ka tutuki i ngā whakaritenga roa o te kaupapa me ngā reiti whakaora roa pai. Hei tāpiri, he mea nui kia mōhio ahakoa he uaua te whiriwhiri i waenga i te whakatinanatanga o tētahi otinga matomato me te whakatinanatanga o tētahi otinga utu-whai hua, he maha ngā wā ka tukuna e ngā otinga maitai kore waikura ngā mea papai o ngā mea e rua.
Kowiri tira hangarua
He mea hangarua 100% te maitai kore waikura, ā, e kore e pirau. He rite tonu te tukanga hangarua o te maitai kore waikura ki te hanga. Hei tāpiri, he maha ngā rauemi mata e hangaia ai te maitai kore waikura, tae atu ki te rino, te nikara, te chromium me te molybdenum, ā, he nui te hiahia mō ēnei rauemi. Ka honoa ēnei āhuatanga katoa hei hanga i te hangarua o te maitai kore waikura kia tino ohanga, ā, ka hua ake he tere hangarua tino teitei. E whakaatu ana tētahi rangahau hou nā te International Stainless Steel Forum (ISSF) tata ki te 92% o te maitai kore waikura e whakamahia ana i roto i ngā mahi hanga whare, hangahanga me ngā mahi hangahanga huri noa i te ao ka whakahokia mai, ka hangaruahia i te mutunga o te mahi. [1]
I te tau 2002, i whakatau tata te International Stainless Steel Forum ko te nui o te hangarua o te maitai kore waikura he tata ki te 60%. I ētahi wā, he teitei ake tēnei. E ai ki a Specialty Steel Industries o Amerika Te Raki (SSINA) ko te nui o te hangarua o te maitai kore waikura raupapa 300 i hangaia i Amerika Te Raki he 75% ki te 85%. [2] Ahakoa he tino pai ēnei tau, he mea nui kia mōhio ehara i te mea koinei te take mō te teitei ake. He roa te ora o te maitai kore waikura i te nuinga o ngā tono. Hei tāpiri, he teitei ake te hiahia mō te maitai kore waikura i ēnei rā i ngā wā o mua. Nō reira, ahakoa te tere hangarua teitei o te maitai kore waikura, kāore te ora o te maitai kore waikura i roto i ngā paipa i te ranea hei whakatutuki i ngā hiahia whakaputa o ēnei rā. He pātai tino pai tēnei.
Kowiri tira pumau
Haunga te whai i tētahi hītori kua whakamātauhia mō te pai o te hangarua me ngā tere whakaora i te mutunga o te oranga, ka tutuki i te maitai kore waikura tētahi atu paearu nui mō ngā rauemi pumau. Mena ka whiriwhiria te maitai kore waikura e tika ana kia rite ki ngā āhuatanga waikura o te taiao, ka taea e te maitai kore waikura te whakatutuki i ngā hiahia o te kaupapa mō tōna oranga katoa. Ahakoa ka ngaro pea te whai huatanga o ētahi atu rauemi i roto i te wā, ka taea e te maitai kore waikura te pupuri i te mahi me te āhua mō te wā roa. Ko te Whare Empire State (1931) he tauira pai o te mahi roa me te whai huatanga utu o te hanganga maitai kore waikura. Kua pāngia te whare e te paru nui i te nuinga o ngā wā, me ngā hua horoi iti rawa, engari e kiia ana kei te pai tonu te maitai kore waikura[iii].
Kowiri tira – te kōwhiringa pumau me te ōhanga
Ko te mea tino whakahihiri ko te whakaaro ki ētahi o ngā āhuatanga e hanga ana i te rino kore waikura hei whiringa taiao ka taea hoki te hanga hei whiringa ōhanga pai rawa atu, inā koa ka whakaarohia te utu mō te roanga o te kaupapa. E ai ki te kōrero i mua ake nei, ka taea e ngā hoahoa rino kore waikura te whakaroa i te roanga o te kaupapa mena ka whiriwhiria te rino kore waikura e tika ana kia tutuki ai ngā āhuatanga waikura o tētahi tono motuhake. Mā tēnei ka piki ake te uara o te whakatinanatanga ki te whakataurite ki ngā rauemi kāore e roa te ora. Hei tāpiri, ka taea e te rino kore waikura mō ngā kaupapa ahumahi te whakaiti i ngā utu tiaki me te tirotiro i te huringa ora me te whakaiti i ngā utu wā whakatā whakaputa. Mō ngā kaupapa hanga, ka taea e te rino kore waikura tika te tu atu ki ētahi taiao uaua me te pupuri tonu i tōna ataahua i roto i te wā. Ka taea e tēnei te whakaiti i ngā utu peita me te horoi mō te roanga o te ora e hiahiatia ana ki te whakataurite ki ngā rauemi rerekē. Hei tāpiri, ko te whakamahinga o te rino kore waikura ka whai wāhi ki te tiwhikete LEED me te āwhina ki te whakanui ake i te uara o te kaupapa. Hei whakamutunga, i te mutunga o te ora o te kaupapa, he nui te uara para o te rino kore waikura e toe ana.
