TeNgongo hapaira EFG, i hangaia e teTe Tipu Whāngai Kiriata-Tautuhi-Tae (EFG)he hua konumohe waikura kotahi-kiriata (Al₂O₃) e mōhiotia ana mō tōna pakari, tōna parakore, me tōna mahi whatu. Mā te tikanga EFG ka taea te whakamahi i ngā ngongo hapairai whakatipu tika i roto i te āhua ngongo, e whakaputa ana i ngā mata maeneene me te matotoru o te pakitara kia rite tonu me te kore e nui te tukatuka i muri. E whakaatu ana ēnei ngongo hapaira i te pumau tino pai i roto ingā taiao pāmahana teitei, pēhanga teitei, me te waikura, he mea nui rawa atu i roto i ngā tono ahumahi me ngā tono pūtaiao matatau.

Hangarau Tipu EFG

Ka whakamahia e te tukanga tipu EFG tētahitaputapu hanga, taputapu rāneie tautuhi ana i ngā rohe o waho, o roto hoki o te karaihe i te mea ka tōia ake te rauemi hapaira rewa. Mā te whakahaere tika i te kiriata rewa e whāngaihia ana e te capillary, ka totoka te karaihe hapaira heirango tuwhera kore hononga.

Mā tēnei tikanga ka mau tonu te hua whakamutunga i te kounga teiteingā ine e hiahiatia ana me te whakatakotoranga tioata, e whakaiti ana i te hiahia mō te miihini tuarua. Nā te mea kua hangaia tika te hapaira i roto i tōna āhua mahi, ka tukuna e te tukanga EFGhe tino pai te whakahokinga, te hua nui, me te tauine iti-utumō te whakaputanga nui.

Ngā Āhuatanga Mahi

Tuku Whānui Whānui:Ka tuku i te mārama mai i te hihi ultraviolet (190 nm) ki te hihi infrared (5 µm), he mea tino pai mō ngā mahi whatu, tātari, me te pūoko.
Te Kaha Hanganga Teitei:Ko te hanganga monocrystalline e whakarato ana i te ātete pai rawa atu ki te ahotea miihini, te ru wera, me te whakarerekētanga.
Te Pūmautanga Wera Tino Pai:Ka taea te mahi tonu i tengā pāmahana neke atu i te 1700°Cme te kore e whakangawari, e ngatata, e pirau rānei i ngā matū.
Ātete Matū me te Plasma:Kāore e pāngia e ngā waikawa kaha, ngā kawakore, me ngā hau tauhohe, e tika ana mō ngā taiao haurua-ira me ngā taiao taiwhanga.
Te Kounga o te Mata Maeneene:Kua ātaahua, kua ōrite hoki te mata EFG kua tupu, ā, ka taea te whakakanapa, te paninga rānei mēnā e hiahiatia ana.
He roa te ora, he iti hoki te tiaki:Nā te ātete o te hapaira ki te kakahu, ka roa te ora o ngā ngongo EFG ahakoa te whakamahinga nui.

Ngā Pātai Auau

Q1: He aha i whiriwhiria ai te tikanga whakatipu EFG mō ngā ngongo hapaira?
A1: Mā te EFG ka taea te tipu tata-āhua-kupenga, ka kore e nui te utu huri, ka tutuki ai he ngongo roa ake, angiangi ake me te āhuahanga tika.

Q2: He ātete ngā ngongo EFG ki te waikura matū?
A2: Āe. He koretake ngā matū o te hapaira, ā, he ātete ki te nuinga o ngā waikawa, ngā kawakore, me ngā hau halogen, he pai ake i ngā uku quartz me te alumina.

Q3: He aha ngā kōwhiringa whakaritenga e wātea ana?
A3: Ka taea te whakarite i te whānui o waho, te matotoru o te pakitara, te whakatakotoranga tioata, me te mutunga o te mata kia rite ki ngā whakaritenga motuhake a te kiritaki, a ngā taputapu rānei.

Q4: He aha te whakataurite o ngā ngongo hapaira EFG ki ngā ngongo karāhe, ki ngā ngongo kuata rānei?
A4: Kāore i rite ki te karāhe, ki te quartz rānei, ka mau tonu te māramatanga me te pono o ngā ngongo hapaira i ngā pāmahana tino wera, ā, ka ātete hoki ki te rakuraku me te horo, ka roa ake te ora mahi.
