Me pēhea te pānga whakarewa o te oumu whakakoi korehau?
He tikanga hou te tikanga whakawera i roto i te oumu korehau, kāore he rerenga i raro i ngā āhuatanga korehau. Nā te mea kei roto te whakawera i te taiao korehau, ka taea te whakakore pai i te pānga kino o te hau ki te mea mahi, nō reira ka taea te whakahaere angitu i te whakawera me te kore e whakamahia he rerenga. Ko te nuinga o te wā e whakamahia ana mō te whakawera i ngā konganuku me ngā koranu he uaua ki te whakawera, pērā i ngā koranu konumohe, ngā koranu titanium, ngā koranu pāmahana-teitei, ngā koranu ātete me ngā uku. He kanapa, he kiato te hononga whakawera, he pai ngā āhuatanga miihini me te ātete ki te waikura. Kāore i te nuinga o te wā ka whakamahia ngā taputapu whakawera korehau mō te whakarewa ngira o te maitai waro me te maitai koranu iti.
Ko ngā taputapu whakakā i roto i te oumu korehau he mea hanga i te oumu korehau me te pūnaha korehau. E rua ngā momo oumu korehau: te ahi wera me te ahi matao. Ka taea te whakamahana i ngā momo oumu e rua mā te hau māori, mā te whakamahana hiko rānei, ā, ka taea te hanga hei oumu taha, oumu raro, oumu runga rānei (momo Kang). Ka taea te whakamahi i te pūnaha korehau i te nuinga o te wā.
Ko te pūnaha korehau te nuinga o te wā ko te wae korehau, te paipa korehau, te takirere korehau, me ētahi atu. Ko te wae korehau he mea hanga mai i te papu miihini hurihuri me te papu tohatoha hinu. Ko te papu miihini anake ka taea te whiwhi i raro iho i te 1.35 × nekehanga korehau o te taumata 10-1pa. Hei whiwhi i te korehau teitei, me whakamahi te papu tohatoha hinu i te wā kotahi. I tēnei wā, ka taea te eke ki te 1.35 × nekehanga korehau o te taumata 10-4Pa. Ka inehia te pēhanga hau i roto i te pūnaha ki te ine korehau.
Ko te whakakoi i roto i te oumu korehau he whakakoi i roto i te oumu, i te rūma whakakoi rānei me te hau e tangohia ana. He tino pai mō te whakakoi i ngā hononga nui me te haere tonu, ā, he pai hoki mō te hono i ētahi konganuku motuhake, tae atu ki te titanium, te zirconium, te niobium, te molybdenum me te tantalum. He whānuitia ngā whakamahinga. Heoi, he ngoikoretanga anō hoki ēnei o te whakakoi korehau:
① He ngāwari te whakarewa ki te whakapūpū i raro i te korehau, nō reira kāore e pai te whakamahi i te whakapūpū korehau mō te whakarewa turanga me te whakarewa whakakī o ngā huānga pūpūpū. Mena e tika ana kia whakamahia, me whakamahi i ngā tikanga tukanga uaua e rite ana.
② He mea aro te whakakoi korehau ki te taratara o te mata, te kounga o te huihuinga me te manawanui ki te taunga o ngā wāhanga kua whakakoitia, ā, me nui te taumata ariā o te taiao mahi me ngā kaiwhakahaere.
③ He uaua ngā taputapu korehau, he nui te haumitanga kotahi, ā, he nui hoki ngā utu tiaki.
Nā, me pēhea te whakatinana i te tukanga whakakoi i roto i te oumu korehau? Ina whakahaerehia te whakakoi i roto i te oumu korehau, me uta te whakarewa hei whakakoi ki roto i te oumu (ki roto rānei i te ipu whakakoi), me kati te tatau o te oumu (me kati rānei te taupoki o te ipu whakakoi), ā, me whakakoi i mua i te whakamahana. Tīmatahia te papu miihini i te tuatahi, hurihia te takirere urungi i muri i te ekenga o te nekehanga korehau ki te 1.35pa, katihia te ara tika i waenga i te papu miihini me te oumu whakakoi, honoa te paipa ki te oumu whakakoi mā te papu horapa, whakawhirinaki ki te papu miihini me te papu horapa kia mahi i roto i te wā poto, papuhia te oumu whakakoi ki te nekehanga korehau e hiahiatia ana, kātahi ka tīmata te whakamahana hiko.
I roto i te tukanga katoa o te pikinga pāmahana me te whakamahana, me mahi tonu te wae korehau ki te pupuri i te taumata korehau i roto i te oumu, ki te whakakore i te turuturu o te hau i ngā atanga rerekē o te pūnaha korehau me te oumu whakawera, ki te tuku i te hau me te mamaoa e piri ana ki te pakitara o te oumu, ki te hononga me te whakarewa, ki te whakakorikori i te konganuku me te waikura, me ētahi atu, kia whakaitihia ai te hau tūturu. E rua ngā momo whakakorikori korehau: te whakakorikori korehau teitei me te whakakorikori korehau wāhanga (korehau waenga). He tino pai te whakakorikori korehau teitei mō te whakakorikori i te konganuku turanga he uaua ki te pirau te waikura (pērā i te konukōre turanga nikara). Ka whakamahia te whakakorikori korehau wāhanga mō ngā wā ka whakakorikori te konganuku turanga, te konganuku whakakī rānei i raro i te pāmahana whakakorikori me ngā āhuatanga korehau teitei.
Mēnā me mahi ngā mahi whakatūpato motuhake hei whakarite i te parakore teitei, me whakamahi te tikanga purenga korehau i mua i te whakakanapa hauwai maroke. Waihoki, mā te whakamahi i te tikanga purenga hauwai maroke, te tikanga purenga hau korehau rānei i mua i te whakakanapa ka āwhina i te whiwhi hua pai ake i roto i te whakakanapa korehau teitei.
