Kauwhata Taipitopito
Kupu Whakataki
I roto i te ahumahi hou, he mea nui te aroturukitanga tika o te pāmahana ki te whakahaere tukanga, te whakapūmau kounga, me ngā pūnaha haumaru. Ko ngā pūoko pāmahana—e whakamahia whānuitia ana—ka tūpono ki ngā taiao uaua pēnei i te pāmahana teitei, ngā matū waikura, ngā pūnaha korehau, me ngā mara plasma. He mea nui te tiaki pai i ēnei pūoko mō te pumau o te mahi. Ko ngā ngongo hapaira, i hangaia mai i te waikura konumohe karaihe kotahi hangai, kua whakamātauhia ko ētahi o ngā rauemi tino pono mō taua tiakitanga. Ka tūhuratia e tēnei tuhinga ngā āhuatanga ahurei o ngā ngongo hapaira, ō rātou whakamahinga kanorau, me te mea nui, ko tā rātou mahi tino pai hei hipoki tiaki i ngā pūoko pāmahana.
Rauemi Pai rawa atu mō ngā Whakamahinga Tino Nui
He momo tioata te hapaira o te waikura konumohe (Al₂O₃) ā, he iti iho i te taimana tōna pakeke, e 9 ana kaute i te tauine Mohs. Nā tēnei pakeketanga tino pai, ka tino ātete ngā ngongo hapaira ki te rakuraku, te kukū, me te pānga ā-mīhini, ahakoa te whakamahinga auau, te whakamahinga nui rānei.
Haunga te kaha ā-mīhini, he tino uara ngā ngongo hapaira mō tō rātou ātete matū. Ka noho pumau, ka noho koretake hoki i te aroaro o te nuinga o ngā waikawa, ngā whakarewa, me ngā hau tauhohe, tae atu ki te hauwai fluoride, te chlorine, me ngā matū whanariki. Mā tēnei ka taea e rātou te mahi pai i roto i ngā tukanga e whakamahi ana i ngā matū kaha, i te plasma rānei.
Hei tāpiritanga, he mea whakamiharo te mahi wera o te hapaira. Ka ātete ki te pāmahana tae atu ki te 2000°C mō te wā roa, me te pupuri tonu i tōna hanganga. Ka tautokona e tōna kawe wera te whakawhiti wera tere, he āhuatanga tino nui ina whakamahia i roto i ngā pūnaha ine pāmahana.
Ko tētahi atu painga nui ko tōna māramatanga whatu puta noa i ngā roangaru ultraviolet, e kitea ana, me te infrared—mai i te 0.3 μm ki te 5 μm. Nā tēnei ka pai ngā ngongo hapaira mō te ine whatu, ngā pūnaha aroturuki whatu-wera rānei.
Ngā Thermocouples me te Hiahia mō te Tiakitanga
He wāhanga nui ngā thermocouples i roto i te whānuitanga o ngā pūnaha, mai i ngā oumu rino me ngā miihini turbine ki ngā tauhohenga semiconductor me ngā taputapu tukanga matū. Ka whakaputahia e ēnei taputapu he ngaohiko i runga i te rerekētanga pāmahana i waenga i ngā konganuku rerekē e rua e honoa ana i tetahi pito. Ahakoa he maha ngā whakamahinga me te pakari o ngā thermocouples, ko te pānga tika ki te wera, ki ngā matū waikura, me te ru miihini ka taea te whakapoto i te roa o te mahi, te whakaheke rānei i te tika o ngā pānui pāmahana.
Koinei te wāhi e whakamahia ai ngā ngongo hapaira hei hipoki tiaki. Mā te takai i te thermocouple ki roto i te ngongo hapaira, ka wehea te pūoko mai i te taiao uaua, me te tuku tonu i te whakawhiti wera pai. Ko te hua he pūoko roa ake te mau, he pono ake hoki e mau tonu ana te tika ahakoa i muri i te roa o te wā e whakamahia ana ki ngā āhuatanga mahi uaua.
Mā te kawe wera o te Sapphire ka taea te tere me te ōrite o te wera ki te thermocouple, ka whakaitihia te whakaroa pāmahana me te whakapai ake i te wā urupare. Hei tāpiri, mā tōna ātete ki te whakaeke matū ka kore te pūoko e pakaru i ngā toenga, te waikura, te kohikohi rauemi rānei—ngā take e pā kino ana ki ngā ringaringa tiaki whakarewa, uku rānei.
