Ucwaningo ngokusetshenziswa kwe-Zirconia Powder ekupholiseni okunembayo okuphezulu
Ngokuthuthuka okusheshayo kwezimboni zobuchwepheshe obuphezulu ezifana ne-electronics kanye nobuchwepheshe bolwazi, ukukhiqiza optical, ama-semiconductors, kanye ne-ceramics ethuthukisiwe, izidingo eziphakeme zibekwa kwikhwalithi yokucubungula indawo yezinto ezibonakalayo. Ikakhulukazi, ekusetshenzisweni okunembe kakhulu kwezingxenye ezibalulekile ezifana ne-sapphire substrates, ingilazi ebonakalayo, namapuleti e-hard disk, ukusebenza kwezinto zokupholisha kunquma ngokuqondile ukusebenza kahle kwemishini kanye nekhwalithi yokugcina yomhlaba.I-Zirconia powder (ZrO₂), i-high-performance material inorganic, kancane kancane ivela emkhakheni we-high-end precision polishing ngenxa yokuqina kwayo okuhle kakhulu, ukuzinza kokushisa, ukumelana nokugqoka, kanye nezakhiwo zokupholisha, iba ngummeleli wesizukulwane esilandelayo sezinto zokupholisha ngemva kwe-cerium oxide ne-aluminium oxide.
I. Izinto ezibonakalayo zeI-Zirconia powder
I-Zirconia iyimpushana emhlophe enezinga eliphakeme lokuncibilika (cishe i-2700 ° C) kanye nezinhlobonhlobo zezinhlaka ze-crystal, kuhlanganise nezigaba ze-monoclinic, tetragonal, ne-cubic. I-zirconia powder eqinisiwe noma eqinile kancane ingatholakala ngokungeza amanani afanelekile we-stabilizers (njenge-yttrium oxide ne-calcium oxide), evumela ukuthi igcine ukuqina kwesigaba esihle kakhulu kanye nezakhiwo zemishini ngisho namazinga okushisa aphezulu.
I-Zirconia powderIzinzuzo ezivelele ziboniswa ngokuyinhloko kulezi zici ezilandelayo:
Ukuqina okuphezulu nekhono elihle kakhulu lokupholisha: Ngokuqina kwe-Mohs okungu-8.5 noma ngaphezulu, ifanele ukupholishwa kokugcina kwezinhlobonhlobo zezinto ezinokuqina okuphezulu.
Ukuzinza kwamakhemikhali okuqinile: Ihlala izinzile endaweni ene-asidi noma ene-alkali kancane futhi ayingenwa kalula ukusabela kwamakhemikhali.
Ukuhlakazeka okuhle kakhulu: I-nano- noma i-submicron-size eguquliwei-zirconia powderbonisa ukumiswa nokugeleza okuhle kakhulu, okwenza kube lula ukupholisha okufanayo.
I-thermal conductivity ephansi kanye nomonakalo ophansi wokungqubuzana: Ukushisa okukhiqizwa ngesikhathi sokupholisha kuncane, kunciphisa ngokuphumelelayo ukucindezeleka okushisayo kanye nengozi yama-microcracks endaweni ecutshunguliwe.
II. Ukufakwa Okujwayelekile Kwe-Zirconia Powder Ekupholisha Okunembayo
1. Ukupholisha kweSapphire Substrate
Amakristalu eSapphire, ngenxa yokuqina kwawo okuphezulu kanye nezakhiwo ezinhle kakhulu zokubona, asetshenziswa kakhulu kuma-chips e-LED, amalensi wewashi, namadivayisi e-optoelectronic. I-Zirconia powder, enobulukhuni obufanayo kanye nezinga eliphansi lomonakalo, iyinto efanelekile yokupholisha ngamakhemikhali (CMP) wesafire. Uma kuqhathaniswa nendabukoi-aluminium oxide polishing powders, i-zirconia ithuthukisa kakhulu ukucaba kwendawo nokuqedwa kwesibuko kuyilapho igcina amazinga okususwa kwezinto, inciphisa imihuzuko nama-microcracks.
2. I-Optical Glass Polishing
Ekucutshungulweni kwezingxenye ze-optical ezifana namalensi anembe kakhulu, amaprism, nobuso bokuphela kwefiber optical, izinto zokupholisha kufanele zihlangabezane nezidingo zokuhlanzeka okuphezulu kakhulu kanye nokucoleka. Ukusebenzisa ukuhlanzeka okuphezului-zirconium oxide powderenosayizi wezinhlayiyana olawulwayo ongu-0.3-0.8 μm njengesisebenzeli sokupholisha sokugcina sifinyelela ubulukhuni obuphezulu obuphansi kakhulu (Ra ≤ 1 nm), sihlangabezana nezimfuneko eziqinile “ezingenasici” zemishini yokubona.
3. I-Hard Drive Platter kanye neSilicon Wafer Processing
Ngokukhula okuqhubekayo kokuminyana kokugcinwa kwedatha, izidingo ze-hard platter surface flatness ziya ngokuya ziba nzima.I-Zirconia powder, esetshenziswa esigabeni esihle sokupholisha sezindawo ze-hard drive platter, ilawula ngokuphumelelayo iziphambeko zokucubungula, ukuthuthukisa ukusebenza kahle kokubhalwa kwediski kanye nempilo yesevisi. Ngaphezu kwalokho, ekupholishweni okunembe kakhulu kwama-silicon wafers, i-zirconium oxide ibonisa ukuhambisana okuhle kakhulu kwendawo kanye nezindawo zokulahlekelwa okuphansi, okuyenza ibe enye indlela ekhulayo ye-ceria.
Ⅲ. Umthelela Wosayizi Wezinhlayiya Nokulawula Kokusabalalisa Kumiphumela Yokupholisha
Ukusebenza kokupholisha kwe-zirconium oxide powder akuhlobene eduze kuphela nobulukhuni bayo bomzimba kanye nesakhiwo se-crystal, kodwa futhi kuthonywa kakhulu ukusabalalisa nokusabalalisa kwezinhlayiyana zayo.
Ukulawula Usayizi Wezinhlayiyana: Osayizi abakhulu ngokwedlulele bangabangela kalula imihuzuko yangaphezulu, kuyilapho okuncane kakhulu kunganciphisa amanani okususwa kwezinto. Ngakho-ke, ama-micropowder noma ama-nanopowder anebanga le-D50 lika-0.2 kuya ku-1.0 μm avame ukusetshenziselwa ukuhlangabezana nezidingo ezahlukene zokucubungula.
Ukusebenza Kokuhlakazeka: Ukuhlakazeka okuhle kuvimbela ukuhlangana kwezinhlayiyana, kuqinisekisa ukuzinza kwesixazululo sokupholisha, futhi kuthuthukisa ukusebenza kahle kokucubungula. Ezinye izimpushana ezisezingeni eliphezulu ze-zirconia, ngemva kokuguqulwa kwendawo, zibonisa izakhiwo ezinhle kakhulu zokumiswa ezixazululweni ezinamanzi noma ezine-asidi ebuthakathaka, ezigcina ukusebenza okuzinzile amahora angaphezu kwamashumi amabili.
IV. Amathrendi okuThuthukisa kanye ne-Future Outlook
Ngokuthuthuka okuqhubekayo kobuchwepheshe be-nanofabrication,i-zirconia powderzithuthukiswa ukuze zibe nobumsulwa obuphakeme, ukusabalalisa usayizi wezinhlayiyana ezincane, kanye nokuhlakazeka okuthuthukisiwe. Izindawo ezilandelayo zidinga ukunakwa esikhathini esizayo:
1. Ukukhiqizwa Okuningi kanye Nokuthuthukiswa Kwezindleko ze-Nano-ScaleI-Zirconia Powder
Ukubhekana nezindleko eziphakeme kanye nenqubo eyinkimbinkimbi yokulungiselela izimpushana ezihlanzekile kuyisihluthulelo sokukhuthaza ukusetshenziswa kwazo okubanzi.
2. Ukuthuthukiswa Kwezinto Ezihlanganisiwe Zokupholisha
Ukuhlanganisa i-zirconia nezinto ezifana ne-alumina ne-silica kuthuthukisa amazinga okususwa kanye namandla okulawula indawo.
3. Isistimu Yoketshezi Olucwebezelayo Oluluhlaza Nobungana Imvelo
Thuthukisa imidiya yokuhlakazeka engeyona enobuthi, ebolayo kanye nezithasiselo ukuze uthuthukise ubungane bemvelo.
V. Isiphetho
I-Zirconium oxide powder, enezici zayo ezinhle kakhulu zezinto ezibonakalayo, idlala indima ebalulekile ngokuya ngokupholisha okunembayo okuphezulu. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe bokukhiqiza kanye nesidingo esikhulayo sembonini, ukusetshenziswa kwei-zirconium oxide powderizosakazeka kakhulu, futhi kulindeleke ukuthi ibe usekelo oluyisisekelo lwesizukulwane esilandelayo sezinto zokupholisha ezisebenza kahle kakhulu. Ezinkampanini ezifanele, ukuhambisana nezitayela zokuthuthukisa izinto kanye nokwandisa izinhlelo zokusebenza ezisezingeni eliphezulu emkhakheni wokupholisha kuzoba indlela eyinhloko yokuzuza ukuhlukaniswa kwemikhiqizo kanye nobuholi bezobuchwepheshe.
