Rangahau mō te Whakamahinga o te Paura Zirconia i roto i te Whakakanapa Tika-Mutunga
I te tere o te whanaketanga o ngā ahumahi hangarau matatau pēnei i te hikohiko me te hangarau mōhiohio, te hanga whatu, ngā haurua-ira, me ngā uku matatau, kei te piki ake ngā whakaritenga mō te kounga o te tukatuka mata rauemi. Ina koa, i roto i te miihini tino tika o ngā wāhanga matua pēnei i ngā papa hapaira, te karāhe whatu, me ngā pereti kōpae mārō, ko te mahi a te rauemi whakakanapa te mea tika hei whakatau i te pai o te miihini me te kounga o te mata whakamutunga.Paura Zirconia (ZrO₂), he rauemi kore-waro mahi-teitei, kei te puta haere i roto i te ao o te oro tino tika nā te mea he tino pakeke, he pumau wera, he ātete ki te kakahu, me ngā āhuatanga oro, ka noho hei tohu mō te whakatupuranga e whai ake nei o ngā rauemi oro i muri i te cerium oxide me te konumohe oxide.
I. Ngā Āhuatanga Rauemi oPaura Zirconia
He paura mā te zirconia, he teitei te ira rewa (tata ki te 2700°C) me ngā momo hanganga tioata, tae atu ki ngā āhua monoclinic, tetragonal, me te cubic. Ka taea te whiwhi i te paura zirconia kua pumau, kua pumau rānei mā te tāpiri i ngā rahinga tika o ngā mea whakau (pēnei i te yttrium oxide me te calcium oxide), ka taea ai te pupuri i te pumau āhua me ngā āhuatanga miihini pai rawa atu ahakoa i ngā pāmahana teitei.
Paura ZirconiaKo ngā painga nui o te hua e kitea nuitia ana i roto i ngā āhuatanga e whai ake nei:
He tino mārō, he tino pai te āheinga whakakanapa: Mēnā he 8.5 te mārō o te Mohs, he pai mō te whakakanapa whakamutunga o ngā momo rauemi tino mārō.
Pūmautanga matū kaha: Ka noho pumau i roto i ngā taiao waikawa, paku kawakore rānei, ā, kāore e pāngia e ngā tauhohenga matū.
He tino pai te marara: He rahi nano- iti iho rānei i te maikorona kua whakarerekētiapaura zirconiahe tino pai te whakatārewatanga me te rere o te wai, e āwhina ana i te oro ōrite.
He iti te kawe wera me te iti o te kino o te waku: He iti noa te wera e puta ana i te wā e orohia ana, ka whakaitihia te ahotea wera me te mōrearea o ngā kapiti moroiti i runga i te mata kua tukatukahia.
II. Ngā Whakamahinga Noa o te Paura Zirconia i roto i te Oro Tika
1. Te Whakakanapa Papa Hapaira
Nā te kaha o te pakeke me te pai o ngā āhuatanga whatu, e whakamahia whānuitia ana ngā tioata hapaira i roto i ngā maramara LED, ngā karāhe mataaratanga, me ngā taputapu optoelectronic. He rite te pakeke o te paura zirconia me te iti o te tere pakaru, he rauemi pai mō te whakakanapa matū me te miihini (CMP) o te hapaira. Ki te whakatauritea ki ngā mea tuku ihopaura whakakanapa waikura konumohe, ka whakapai ake te zirconia i te papatahi o te mata me te whakaotinga whakaata, me te pupuri tonu i te tere tango rauemi, me te whakaiti i ngā karawarawa me ngā kapiti moroiti.
2. Te Whakakanapa Karāhe Whatu
I te tukatuka i ngā wāhanga whatu pēnei i ngā karaihe arotahi tino tika, ngā porotiti, me ngā mata pito muka whatu, me tutuki i ngā rauemi whakakanapa ngā whakaritenga tino teitei mō te ma me te ātaahua. Mā te whakamahi i te parakore teiteipaura waikura zirconiummā te rahi matūriki whakahaeretia o te 0.3-0.8 μm hei ākena whakakanapa whakamutunga ka tutuki te taratara o te mata tino iti (Ra ≤ 1 nm), e tutuki ai ngā whakaritenga "kore hapa" pakari o ngā taputapu whatu.
3. Te Tukatuka i te Pereti Puku Mārō me te Waferi Hiraka
I te piki haere tonu o te mātotoru rokiroki raraunga, kei te kaha haere ngā whakaritenga mō te papatahi o te mata o te pereti puku mārō.Paura Zirconia, e whakamahia ana i te wāhanga whakakanapa pai o ngā mata pereti puku mārō, e whakahaere pai ana i ngā hapa tukatuka, e whakapai ake ana i te pai o te tuhi kōpae me te roa o te mahi. Hei tāpiri, i roto i te whakakanapa tino tika o ngā anga silicon, he pai te hototahi o te mata me ngā āhuatanga iti o te ngaronga o te zirconium oxide, ā, he huarahi kē atu tēnei hei whakakapi i te ceria.
Ⅲ. Te Pānga o te Rahi Matūriki me te Whakahaere Marara ki ngā Hua Whakakanapa
Ko te mahi whakakanapa o te paura zirconium oxide e pā tata ana ki tōna pakeketanga ā-tinana me te hanganga tioata, engari he nui hoki te awe o tōna tohatoha me te mararatanga o te rahi matūriki.
Te Whakahaere Rahi o te Matūriki: Ka taea e ngā rahi matūriki nui rawa te whakararu i te mata, engari ka taea e te iti rawa te whakaiti i te tere tango rauemi. Nō reira, ka whakamahia ngā paura moroiti, ngā paura nano rānei me te awhe D50 o te 0.2 ki te 1.0 μm hei whakatutuki i ngā whakaritenga tukatuka rerekē.
Te Mahi Marara: Mā te marara pai ka ārai i te kohikohinga o ngā matūriki, ka whakarite i te pumau o te otinga whakakanapa, ā, ka whakapai ake i te pai o te tukatuka. Ko ētahi paura zirconia kounga teitei, i muri i te whakarerekētanga o te mata, ka whakaatu i ngā āhuatanga whakatārewatanga pai rawa atu i roto i ngā otinga wai, waikawa ngoikore rānei, ka mau tonu te mahi pumau mō ngā haora maha neke atu.
IV. Ngā Auahatanga Whakawhanake me te Tirohanga ki te Ao Whānui
I te whanaketanga tonu o te hangarau hanga-nano,paura zirconiakei te whakapai ake kia teitei ake te parakore, kia whaiti ake te tohatoha rahi matūriki, me te whakarei ake i te marara. Ko ngā wāhanga e whai ake nei me aro atu ā muri ake nei:
1. Te Hanga Papatipu me te Arotau Utu o te Nano-ScalePaura Zirconia
Ko te aro atu ki te utu nui me te uaua o te tukanga whakarite paura parakore te mea nui hei whakatairanga i tōna whakamahinga whānui.
2. Te Whakawhanaketanga o ngā Rauemi Whakakanapa Hiko
Mā te whakakotahi i te zirconia me ngā rauemi pēnei i te alumina me te silica ka pai ake te tere tango me te kaha whakahaere mata.
3. Pūnaha Wai Whakakanapa Kakariki, Ātaahua hoki ki te Taiao
Te whakawhanake i ngā mea horapa kore-paitini, pirau-ora me ngā tāpiringa hei whakarei ake i te atawhai ki te taiao.
Whakamutunga
Paura waikura zirconium, me ōna āhuatanga rauemi tino pai, kei te piki haere te hiranga o te mahi whakakanapa tino tika. Me te haere tonu o ngā whanaketanga hangarau hanga me te pikinga o te tono ahumahi, ko te tono opaura waikura zirconiumka horapa haere, ā, e tūmanakohia ana ka noho hei tautoko matua mō te whakatupuranga e whai ake nei o ngā rauemi whakakanapa mahi-teitei. Mō ngā kamupene e tika ana, ko te whai i ngā au o te whakapai ake rauemi me te whakawhānui ake i ngā tono teitei i roto i te mara whakakanapa he ara matua ki te whakatutuki i te rerekētanga hua me te kaiārahi hangarau.
