Ngā Pūrongo - He aha te rerekētanga i waenga i ngā puranga rino hurihuri wera me ngā puranga rino hurihuri matao

I roto i te mara o te miihini ā-iwi me te hanganga,Ngā Puranga Rau Rino(e kiia pinepinetia ana kopuranga pepa) kua roa nei hei rauemi tūāpapa mō ngā kaupapa e hiahia ana kia mau te oneone, kia ātete ki te wai, me te tautoko hanganga—mai i te whakapakari i te tahataha awa me te tiaki takutai ki te keri i raro i te whenua me ngā arai hanga rangitahi. Heoi, kāore i te rite te hanganga o ngā Puranga Rino katoa: e rua ngā tukanga hanga matua—te hurihuri wera me te hanga matao—e whakaputa ana i ngā hua motuhake, arā, ko ngā Puranga Rino Hurihia Wera me ngā Puranga Rino Hurihia Matao, he āhuatanga ahurei tō ia mea e pai ai mō ngā tono motuhake. He mea nui te mārama ki ō rātou rerekētanga mō ngā miihini, ngā kaimahi kirimana, me ngā kaiwhakahaere kaupapa ki te whakatau i ngā whakataunga utu-whai hua, e aro ana ki te mahi.

Ngā momo tukanga hanga puranga rino e rua

Ko ngā tukanga hanga o ngā momo paparanga pepa e rua i whakatakoto i te turanga mō ō rāua āhuatanga rerekē.Ngā Puranga Rau Rino Hurihia Weraka hangaia mā te whakamahana i ngā pereki maitai ki ngā pāmahana tino teitei (i runga ake i te 1,000°C) kia ngawari ra ano te whakarewa, kātahi ka tukuna mā roto i tētahi raupapa roera hei hanga i roto i ngā kōtaha honohono (pēnei i te momo-U, momo-Z, tukutuku tika rānei) e tautuhi ana i te puranga rau. Mā tēnei tukanga pāmahana teitei ka taea te hanga i ngā wāhanga whakawhiti uaua, pakari, ā, ka whakarite kia ōrite te matotoru o ngā rauemi, nā te mea ka whakakorea e te wera ngā ahotea o roto i te maitai. He rerekē,Ngā Puranga Rau Rino Hurihia Mataohe mea hanga mai i ngā koiri maitai papatahi kua oti te tapahi, kua hangaia hei kōtaha honohono mā te whakamahi i ngā roera makariri—kāore he wera nui e pāngia ana i te wā e hangaia ana. Ko te tukanga hurihuri makariri e whakawhirinaki ana ki te ngāwari o te maitai i te pāmahana rūma, he mea tino pai mō te whakaputa i ngā kōtaha māmā ake, paerewa ake, ahakoa ka puta pea he ahotea iti o roto e hiahia ana kia tukatukahia i muri (pēnei i te whakamahana) mō ētahi tono kawenga teitei.

Ngā āhuatanga mahi me te hanganga o ngā momo puranga rino e rua

Ko ngā āhuatanga mahi me te hanganga e wehewehe ana i ngā momo e rua. He tino kaha, he roa hoki te mau o ngā puranga pepa hurihuri-wera: he nui ake te kaha kume, te kaha tuku, me te ātete pānga nā te hanganga hurihuri-wera, ā, he pai mō ngā kaupapa taumaha, roa-wā. Hei tauira, he pai ake ngā puranga pepa hurihuri-wera i roto i ngā kaupapa keri hohonu (me tū atu ngā puranga pepa ki te pēhanga whenua nui) me ngā hanganga tiaki takutai tūturu (e pāngia ana e te huarere kino me te waikura o te wai). Ina pania ki te paninga (pēnei i te epoxy, te konutea rānei), ka pai ake te ātete waikura o ngā puranga pepa hurihuri-wera, nā te mea ka whakarite te hanganga rauemi ōrite kia piri ōrite te paparanga tiaki. Ko ngā puranga pepa hanga-matao, i tētahi atu taha, he mama ake, he iti ake te utu mō ngā tono rangitahi, waenga-kawenga rānei. Nā te iti o te taumaha, ka māmā ake te kawe me te tāutanga—he iti ake ngā taputapu me te mahi e hiahiatia ana—he pai mō te tautoko whare wā poto, ngā taiepa waipuke rangitahi, ngā kaupapa rūma noho rānei, kāore te kaha kawe kawenga nui i te mea nui. Ahakoa he iti iho tōna kaha i ērā atu momo hanga-wera, kua whānui ake te whakamahinga o ngā whanaketanga hou o te hangarau hanga-matao (pērā i ngā koranu maitai kaha-tiketike) i roto i ngā hanganga āhua-tūturu.

Te utu me te wātea o ngā momo puranga rino e rua

He mea nui anō hoki te utu me te wātea hei whiriwhiri i waenga i ngā mea e rua. Ko ngā Puranga Rau Rino Hurihia Matao he iti ake te utu tīmatanga, nā te mea he pai ake te penapena hiko i roto i te tukanga hurihanga matao, he iti ake te hiahia ki ngā taputapu motuhake, ā, he iti ake te para rauemi e puta mai ana i te hurihanga wera. He ngāwari ake hoki te wātea i roto i ngā rahi paerewa, he poto ake ngā wā arahi mō te hanga - he mea nui mō ngā kaupapa he poto ngā wā mahi. He rerekē, he nui ake ngā utu hanga mō ngā Puranga Rau Rino Hurihia Wera nā te tukanga whakamahana nui-hiko me te hiahia mō ngā mīhini hurihanga uaua ake. Ka tāpirihia hoki e ngā kōtaha ritenga (i hangaia mō ngā whakaritenga kaupapa ahurei) ō rātou utu me te wā arahi. Heoi, ko tō rātou roa o te wā ka whakakore i te haumitanga tuatahi teitei ake: i roto i ngā hanganga pumau, he iti ake te tiaki e hiahiatia ana mō ngā Puranga Rau Rino Hurihia Wera, ā, he roa ake te ora ratonga, ka whakaitihia ngā utu huringa ora i roto i te wā.

Ngā painga o ia tangata

Hei whakarāpopototanga, he mea nui te mahi a ngā puranga rau hurihuri wera me ngā puranga rau hanga-matao i roto i te hanganga o ēnei rā, engari nā ō rātou rerekētanga i roto i te hanga, te mahi, me te utu ka pai ake ai mō ngā tono motuhake. E mōhiotia ana ngā puranga rau hurihuri wera mō ō rātou kaha, te roa, me te pai mō ngā tono pumau, taumaha, ko ngā puranga rau hanga-matao ia he iti te utu, he ngāwari te tāutanga, me te ngāwari, e pai ai mō ngā kaupapa rangitahi, mahi-waenga rānei. I te mea kei te tipu haere tonu te hiahia mō te hanganga pumau me te whai hua, e matapaetia ana e ngā tohunga ahumahi ka haere tonu te auahatanga i roto i ngā tukanga e rua, mai i ngā koranu kaha-teitei kua whakapaitia ake ki te hangarau hurihuri wera e whai hua ana ki te pūngao, ka whakawhānui ake i te maha o ngā puranga rau me ngā otinga puranga rau puta noa i te ao.
