He aha te mea tino hira ai ngā pūnaha tuku hau UHP?
I roto i te hanga haurua-haurua—ngā tukanga pēnei i te whakairo, te CVD, te whakauru katote, me te tuhi-ā-ringa—me tino parakore ngā hau tukanga, ko te tikanga he 99.9999% (6N) tae atu rānei ki te 99.99999% (7N). Ahakoa ngā parahanga iti i te taumata ppb (ngā wāhanga mō ia piriona) ppt rānei (ngā wāhanga mō ia tiriona)—pērā i te makuku, te hāora rānei—ka taea te whakaputa i ngā hapa kino pēnei i te angiangi o te waikura kuaha, ngā āputa whakarewa, ngā ara iahiko poto rānei i runga i ngā papa, ka taea te whakangaro i ngā puranga katoa.
Ko te kaupapa matua o te pūnaha tuku hau UHP ko te kawe i ngā hau mai i te pūtake ki te taputapu tukatuka, me te kore e heke te parakore, kia kore ai e poke, e turuturu hoki i ngā wāhi katoa.
He aha ngā ngongo EP e noho ai hei poutokomanawa mō ngā pūnaha UHP?
He mea hanga ngā ngongo EP (Electropolish) mai i te maitai kore waikura ka pāngia e te tukanga whakakanapa hiko, ka puta he mata o roto rite ki te whakaata. Nā tēnei ka waiho hei "uaua toto" tino nui mō te tohatoha hau UHP.
Te Horoi Tino Pai – Te Ārai i te Pūtake
Ka whakaitihia e te tukatuka EP te taratara o roto o te mata (Ra) ki te 0.13 µm – 0.25 µm, ki raro iho rānei. Ka whakakorea e tēnei whakaotinga tino maeneene ngā kapiti moroiti me ngā wāhi mimiti, ā, kāore he wāhi e piri ai ngā matūriki, ngā katote konganuku, te makuku rānei.
Ātete Waikura Whakarei – Tiakitanga Parakore
Mā te mahi whakakoi hiko ka tangohia ngā poke o te mata, ka hangaia he paparanga kore mahi e nui ana te chrome-waikura, ka nui ake te ātete ki ngā hau waikura pēnei i te Cl₂, te CF₄, me te HCl. Ka ārai tēnei i te waikura o te pakitara paipa ka puta he matūriki, he paru rānei i waho.
Te Pai Ake o te Rere me te Tere o te Whakakore
Ka whakaitihia e te pakitara o roto maeneene te ātete rere, ka tere ake te horoinga o te pūnaha me te whakakapinga hau. I roto i ngā tukanga e hiahia ana kia tere te whakawhiti hau, ka whakapotohia ngā wā huringa, ka whakanui ake hoki i te tere whakaputa hau.
Rauemi Tino Pai – Te Paerewa "Karauna"
He mea hanga ngā ngongo EP kounga teitei mai i te maitai kore waikura 316L VIM‑VAR (Vacuum Induction Melting + Vacuum Arc Remelting). Mā tēnei tukanga rewa-rua ka tino parakore te konganuku turanga, koinei te whakaritenga matua mō te whakatutuki i te mahi tino pai a te EP.
Ngā horopaki tono matua
•
Ngā Tukanga Matua– Te tukunga o ngā hau tauhohenga parakore teitei mō te whakairo, te CVD, te whakatō katote, me te tuhi whakaahua.
•
Ngā Hau Motuhake– Te whakahaere haumaru i ngā hau mura, paitini, waikura rānei pērā i te SiH₄, PH₃, Cl₂, me te BCl₃. Mō ngā hau tino morearea, ka whakamahia pinepine ngā ngongo EP takirua (ngongo o roto mō te hau, te koti o waho kua tangohia, kua horoia rānei ki te hauota hei aroturuki i te turuturu).
•
Pūmārō Hira– E whakamahia ana i roto i ngā panera tohatoha hau (VMB), ngā kāpata hau, me ngā hononga taputapu tukatuka ina hiahiatia ngā mata o roto tino ma.
Kei tua atu i te Ngongo: Ētahi atu Mea Matua mō tētahi Pūnaha UHP Katoa
Hei whakarite i te pono tuturu, me whakauru hoki e te pūnaha:
•
Te Whakarewa Āmiomio Aunoa Katoa– Ka mahia i roto i ngā rūma ma ISO Class 5 (Class 100) neke atu rānei, ka whakakorea ngā rerekētanga whakarewa ā-ringa me ngā mōrearea poke.
•
Ngā Hononga Hiri Kanohi Whakarewa Katoa– Pērā i ngā momo VCR®, W-Seal rānei, e whakawhirinaki ana ki ngā gasket whakarewa hei ārai i te turuturu.
•
Te Horoi me te Tākai Pūmau– Ko ngā ngongo EP ka horoia ki te wai parakore, ka whakamarokehia, ka horoia ki te hauota i mua i te tāpiri rua ki roto i te takai rūma ma hei pupuri i tō rātou parakore "i te wā i tukuna ai" tae noa ki te tāutanga.
Ehara i te mea he paipa noa iho ngā ngongo EP—koinei te rārangi parepare tuatahi i roto i te tuku hau haurua-haurua. Ko tōna mata tino maeneene, te ātete ki te waikura, me te parakore o ngā rauemi kounga teitei ka pā tika ki te hua o te wafer, te pono o te taputapu, me te hua whānui o te hanga. I roto i te ao o ngā pona sub-5nm me ngā tahua hapa e kikī haere ana, ehara i te mea whiriwhiri ngā ngongo EP—he mea tūāpapa.
