AKo te ngākau o ia whakamahana hiko he huānga whakamahana. Ahakoa te rahi o te whakamahana, ahakoa he wera hihi, he hinu, he hau rānei, kei roto i tētahi huānga whakamahana ko tana mahi he huri i te hiko hei wera.

SI ētahi wā ka kitea te wāhanga whakamahana, e mura ana i roto i te mata o te ahi tiaki. I ētahi wā ka huna i roto, e tiakina ana e ngā anga whakarewa me te kirihou, engari e pupuhi ana i te wera. Ko te āhua o te wāhanga whakamahana me tōna hoahoa ka pā tika ki te pai o te mahi a te whakamahana, me te roa o tana mahi tonu.

Waea Ātete

BI tēnei wā, ko ngā waea whakarewa, ko ngā rīpene rānei te rauemi e whakamahia whānuitia ana mō ngā wāhanga whakamahana, e kiia ana ko ngā waea ātete. Ka taea ēnei te takai piri, te whakamahi rānei hei rīpene papatahi, i runga i te āhua o te taputapu. Ka roa ake te waea, ka nui ake te wera ka puta.

Tahakoa e whakamahia ana ngā momo koranu mō ngā mahi motuhake,Nichromekoinei tonu te mea tino rongonui e whakamahia ana mō ngā whakamahana wāhi me ētahi atu taputapu iti.He koranu te nichrome 80/20 o te 80% nickel me te 20% chromium.Nā ēnei āhuatanga pai hei whakamahana:

1. Ātete teitei
2. He ngāwari ki te mahi me te hanga
3. Kāore e waikura, e pirau rānei i te hau, nō reira ka roa ake te ora
4. Kāore e tino whānui ina wera
5. Teitei o te pūmahana rewa tata ki te 2550°F (1400°C)

OKo ētahi atu koranu e kitea whānuitia ana i roto i ngā huānga whakamahana ko te Kanthal (FeCrAl) me te Cupronickel (CuNi), ahakoa kāore ēnei e whakamahia whānuitia ana i roto i ngā whakamahana wāhi.

Ngā whakamahana uku

RNō nā tata nei, kua piki haere te rongonui o ngā waeine whakamahana uku. He rite tonu te mahi a ēnei i raro i ngā kaupapa ātete hiko me te waea ātete, engari ka whakakapia te konganuku e ngā pereti uku PTC.

PKo te uku TC (te tikanga ko te barium titanate, BaTiO3) i tapaina pērātia nā te mea he pai te tauwehenga ātete wera o tōna, arā, ka piki ake te ātete i te wā e whakamahanatia ana. Ka mahi tēnei āhuatanga whakawhāiti-ake hei whakamahana taiao – ka tere te wera o te rauemi uku, engari ka noho papatahi ina tae ki te pāmahana kua tautuhia. Ina piki te pāmahana, ka piki ake te ātete, ka heke te putanga wera. Ka whakaratohia he whakamahana ōrite me te kore he rerekētanga mana.

TKo ngā painga o ngā whakamahana uku ko:

1. Whakamahana tere
2. He iti te pāmahana o te mata, he iti te mōrearea ahi
3. Te roa o te ora
4. Mahi whakahaere-ā-koe

II te nuinga o ngā whakamahana rūma, he rite te hanganga o ngā panera uku ki te honikoma, ā, he mea tāpiri ki ngā ārai konumohe hei tuku i te wera ki te hau, me te kore āwhina o te pā.

Ngā Rama Wera Hiko, Ngā Rama Wera Pūwhero rānei

TKo te miro i roto i te pūrama rama he waea ātete, ahakoa he mea hanga ki te tungsten hei whakanui ake i te putanga mārama ina werahia (arā, te incandescence). Ko te miro wera kei roto i te karāhe, i te quartz rānei, e whakakīia ana ki te hau kore mahi, e tangohia ana rānei te hau hei tiaki i a ia mai i te waikura.

Ihei whakamahana wāhi, ko te miro rama wera te tikangaNichrome, ā, ka whāngaihia te pūngao mā roto i taua mea i raro i te mana mōrahi, kia tukuna ai e te miro te whero whero hei utu mō te mārama e kitea ana. Hei tāpiri, he maha ngā wā ka pania te uhi quartz ki te whero hei whakaiti i te nui o te mārama e kitea ana e tukuna ana (ka mamae pea ō tātou kanohi, ki te kore). Ko te nuinga o te wā ka tautokona te wāhanga whakamahana e te whakaata e tohutohu ana i te wera ki te huarahi kotahi.

TKo ngā painga o ngā rama wera hihi ko:

1. Kāore he wā whakamahana, ka mahana tonu koe
2. Whakahaerehia marietia, nā te mea kāore he hau wera e hiahia ana ki te pā hau
3. Whakaratohia he whakamahana wāhi i ngā wāhi tuwhera me waho, kia marara ai te hau wera

NAhakoa te momo whakamahana o tō whakamahana, kotahi te painga o ēnei katoa: tata ki te 100% te whai huatanga o ngā whakamahana ātete hiko. Ko te tikanga, ka hurihia te hiko katoa e uru ana ki te ātete hei wera mō tō wāhi. He painga tēnei ka taea e te katoa te maioha, inā koa ka tae ki te wā utu pire!
