Ko te waea nichrome, he koranu nickel-chromium (ko te tikanga he 60-80% nickel, 10-30% chromium), he rauemi mahi e whakanuia ana mō tōna ranunga ahurei o te pumau pāmahana teitei, te ātete hiko pumau, me te ātete ki te waikura. Nā ēnei āhuatanga ka tino hiahiatia puta noa i ngā ahumahi kanorau—mai i ngā taputapu o ia rā ki ngā tautuhinga ahumahi e hiahiatia ana—ā, kua hangaia ā mātou hua waea nichrome kia pai ai te mahi i roto i ia whakamahinga.
1. Ngā Wāhanga Whakamahana: Te Whakamahinga Matua
Ko te whakamahinga whānui o te waea nichrome kei roto i te hanga i ngā wae whakamahana, nā tōna kaha ki te huri i te pūngao hiko ki te wera me te whai hua me te pono. I roto i ngā taputapu o te whare, ka whakakahangia ngā koiri whakamahana i roto i ngā tōstare, i ngā whakamaroke makawe, i ngā oumu hiko, me ngā whakamahana wāhi. Kāore i rite ki ētahi atu konganuku e whakangawari ana, e waikura ana rānei i ngā pāmahana teitei, ka mau tonu te hanganga o tā mātou waea nichrome ahakoa ka werahia ki te 1,200°C, kia mau tonu ai te oma o ngā taputapu mō ngā tau. Hei tauira, kua hangaia ngā koiri whakamahana i roto i tā mātou waea nichrome me te ātete tika (te tikanga 1.0-1.5 Ω·mm²/m) hei tuku wera ōrite—kāore he wāhi wera, he mahana pumau anake e whakapai ake ana i te roa o te whakamahinga o te taputapu.
I roto i ngā taiao ahumahi, ko te waea nichrome te pou tuarā o ngā pūnaha whakamahana pāmahana teitei. Ka whakamahia i roto i ngā oumu ahumahi mō te whakamahana whakarewa, ngā mīhini whakarewa kirihou, me ngā oumu whakamahana, ka roa te wā e pāngia ana e te wera nui, kāore e pirau. Ko tā mātou waea nichrome taumaha (0.5-5mm te whānui) he mea hanga mō ēnei mahi, me te ātete waikura kua whakarei ake kia tu atu ai ki te mahi tonu i roto i ngā taiao ahumahi uaua.
2. Ngā Taputapu Taiwhanga me ngā Taputapu Pūtaiao
He mea nui te waea nichrome i roto i ngā taiwhanga, he mea nui te whakamahana tika. Ka whakamahia i roto i ngā mura Bunsen (hei wāhanga whakamahana mō ngā momo hiko), ngā papa whakamahana mō te whakamahana pounamu, me ngā rūma e whakahaeretia ana te pāmahana. He tino pai tā mātou waea nichrome ine-iti (0.1-0.3mm te whānui) i konei—nā tōna ngāwari teitei ka taea te hanga hei koiri iti, uaua, ā, nā tōna ātete pumau ka whakarite kia tika te whakahaere pāmahana, he mea nui mō ngā whakamātautau tairongo.
3. Ngā Wāhanga Ātete me ngā Whakamahinga Motuhake
Haunga te whakamahana,waea nichromeNā te ātete hiko ōrite o tēnei mea, he mea tino pai mō ngā huānga ātete i roto i ngā hikohiko, pērā i ngā ātete pumau me ngā potentiometers. Ka kitea hoki te whakamahinga i roto i ngā mara motuhake: i roto i te tānga 3D, ka whakakaha i ngā moenga wera hei piri ki te miro; i roto i te rererangi, ka whakamahia mō ngā huānga whakamahana iti i roto i ngā waka rererangi; ā, i roto i ngā kaupapa whakangahau (pērā i ngā rēriwe tauira, i ngā whakamahana DIY rānei), nā te ngāwari o te whakamahi me te utu iti ka tino pai ki a ia.
Kei te wātea ā mātou hua waea nichrome i roto i te whānuitanga o ngā momo (tae atu ki te NiCr 80/20 me te NiCr 60/15) me ngā whakaritenga, mai i ngā waea tino pai mō ngā tono ngawari ki ngā waea matotoru mō ngā whakamahinga ahumahi taumaha. Ka whakamatautauria ia rōra ki te kounga tino pakari—tae atu ki te manatoko hanganga koranu me ngā tirotiro ātete—kia tutuki ai ngā paerewa ahumahi. Ahakoa e hiahia ana koe ki tētahi huānga whakamahana pono mō ngā taputapu whare, ki tētahi otinga pakari rānei mō ngā oumu ahumahi, ka tukuna e tā mātou waea nichrome te mahi, te roa o te ora, me te ōritetanga e hiahiatia ana e koe.
