Te hura i te Pūtaiao kei Muri i te Cerium Oxide: Me pēhea te whakatutuki i te Tino Pai o te Mata Taumata-Atomo
I roto i te rāngai hanga tino tika o ēnei rā, he mea nui te whakatutuki i ngā mata karaihe tino maeneene hei whakarite i te mahi whatu tino pai. Kei te ngako o tēnei tukanga ko te paura whakakanapa cerium oxide (CeO₂)[1], he rauemi matua e kore e taea te whakakapi mō te whakakanapa karaihe kounga teitei, e whakanuia ana mō ōna āhuatanga ahurei. Ko tōna hiranga ehara i te mea ko tōna pai o te whakakanapa engari ko tōna kaha ki te whakatutuki i te tika o te mata nanoscale, e whakatutuki ana i ngā whakaritenga hangarau pakari mai i te karaihe papatahi noa ki ngā arotahi whatu rererangi.
Ngā Mātāpono Pūtaiao: Me pēhea te āhei o te Cerium Oxide ki te tango rauemi taumata-atomika
Ko te hiranga o te paura whakakanapa cerium oxide i ahu mai i ōna āhuatanga ā-tinana, ā-matū hoki. I te taha tinana, he rite te rahi o te matūriki iti-micron o te paura cerium oxide kounga teitei (ko te D50 kei roto i te awhe o te 0.3-1.5μm) me te pakeke teitei (tata ki te 7 i runga i te tauine Mohs). Mā tēnei āhuatanga hanganga ka taea e ia te whakaputa piriona o ngā pūwāhi tapahi moroiti i te wā o te tukanga whakakanapa, ka āwhina i te pakū ōrite o te mata karaihe.
He mea nui, ko tana tikanga whakakanapa matū ko te hanganga o tētahi paparanga whakawhiti mā te hononga matū Ce-O-Si i waenga i te cerium oxide me te mata o te karāhe silicate i raro i te pēhanga me te waku. Ka hangaia tonutia tēnei paparanga whakawhiti me te tangohia mā te kutikuti miihini, ka tutuki ai te tango rauemi taumata-ngota. Ko te hua o tēnei mahi tahi miihini-matū ka nui ake ngā tere tango rauemi me te whakaiti i te kino o te mata ki te whakataurite ki te whakakanapa miihini parakore.
Te Mahi Hangarau: Te Ine i te Kounga o te Paura Whakakanapa Cerium Oxide
Ko ngā tohu hangarau matua mō te aromatawai i te paura whakakanapa cerium oxide e hanga ana i tētahi pūnaha kounga whānui:
Te Ihirangi o te Waikura Whenua Onge (REO) me te Parakore o te Waikura Cerium: Me ≥ 90% te REO o ngā paura whakakanapa kounga teitei, kia rite ai, kia pumau ai hoki ngā tauhohenga matū whakakanapa.
Te Tohatoha Rahi o te Matūriki: Ko te D50 (te rahi waenga o te matūriki) me te D90 (te rahi o te matūriki e kitea ai te 90% o ngā matūriki) e whakatau tahi ana i te tika o te whakakanapa; mō te whakakanapa whatu tino tika, me D50 ≤ 0.5μm me te D90 ≤ 2.5μm, e tohu ana i te tohatoha rahi whaiti.
Te Pūmautanga o te Whakatārewatanga: Me pupuri e ngā hua kounga te whakatārewatanga pumau mō te 60-80 meneti i roto i te wai whakakanapa kia kore ai e whakakanapahia te koretake nā te oneone.
Ko ēnei tohu katoa te tauira aromatawai mahi mō te paura whakakanapa ceria, ā, he pānga tika ki ngā hua whakakanapa whakamutunga.
Te Whenua Taupānga: Mai i te Karāhe o ia Rā ki te Hangarau Hou
Kua horapa te hangarau whakakanapa waikura cerium ki ngā momo ahumahi hou:
Ngā Ahumahi Whakaaturanga me te Optoelectronic: He mea nui hei whakamahi mō te whakakanapa i te karāhe arataki ITO, te karāhe uhi tino angiangi, me ngā panera whakaaturanga tioata wai, kia tutuki ai te taratara iti-nanometer me te kore e kino te kiriata ITO.
Ngā Taputapu Whatu: E whakamahia ana i roto i te tukatuka i ngā wāhanga rerekē pēnei i ngā karāhe arotahi, ngā porotiti, me ngā tātari whatu, he tino pai te cerium Oxide mō te whakakanapa tika o te karāhe whatu motuhake, pēnei i te karāhe kiripaka, ka whakaiti i te wā whakakanapa mā te 40%-60%.
Te Hanga Taputapu Tino Pai: I roto i te hanga o ngā huānga whatu tino tika pērā i ngā anga silicon semiconductor, ngā matapihi tirotiro waka mokowhiti, me ngā whakaata gyroscope laser, ka taea e te waikura nano cerium teitei-parakore (parakore ≥ 99.99%, rahi matūriki ≤ 0.3μm) te whakatutuki i te papatahi o te mata taumata-atomika.
Te Tukatuka Whakapaipai me te Toi: E whakamahia ana mō te whakapaipai mata o ngā taonga papai pērā i ngā kohatu hangai, ngā mahi toi karaihe, me ngā mata mataaratanga papai, ka tukuna he pānga tirohanga mārama, kāore he rakuraku.
Mai i te kanapa o ngā mata waea atamai ki te tino tika o ngā karāhe karuārai ātea, kua tutuki i te paura whakakanapa cerium oxide ngā whanaketanga nui i roto i te wheako tirohanga tangata mā roto i tana mahi i roto i te ao moroiti. Ko tēnei hangarau, e whakakotahi ana i te pūtaiao rauemi, te matū atanga, me te miihini tika, kei te pana tonu i ngā rohe o te maimoatanga mata karāhe. Ko ia taunekeneke moroiti i roto i te tukanga whakakanapa e whakaatu ana me pēhea te huri i ngā āhuatanga taiao o tētahi rauemi hei mana e whakarerekē ana i tā tātou tirohanga tirohanga.
