Ucwaningo mayelana nokusetshenziswa kwe-Zirconia Powder ekupholiseni okunembe kakhulu
Ngokuthuthuka okusheshayo kwezimboni zobuchwepheshe obuphezulu ezifana ne-elekthronikhi kanye nobuchwepheshe bolwazi, ukukhiqizwa kwe-optical, ama-semiconductor, kanye ne-ceramics ezithuthukisiwe, izidingo eziphakeme zibekwa ekhwalithini yokucubungula ubuso bezinto ezibonakalayo. Ikakhulukazi, ekusetshenzisweni komshini wokulungisa izinto ngokunemba okukhulu kwezingxenye ezibalulekile njenge-sapphire substrates, ingilazi ye-optical, kanye nama-hard disk platter, ukusebenza kwezinto zokupholisha kunquma ngqo ukusebenza kahle komshini kanye nekhwalithi yokugcina yobuso.Impuphu yeZirconia (ZrO₂), into engaphili esebenza kahle kakhulu, ivele kancane kancane emkhakheni wokupholisha ngokunemba okuphezulu ngenxa yobulukhuni bayo obuhle kakhulu, ukuzinza kokushisa, ukumelana nokuguguleka, kanye nezakhiwo zokupholisha, iba ngummeleli wesizukulwane esilandelayo sezinto zokupholisha ngemuva kwe-cerium oxide ne-aluminium oxide.
I. Izakhiwo zezinto ezibonakalayoI-Zirconia Powder
I-Zirconia iyimpuphu emhlophe enezinga lokuncibilika eliphezulu (cishe ama-2700°C) kanye nezakhiwo ezahlukahlukene zekristalu, kufaka phakathi izigaba ze-monoclinic, tetragonal, kanye ne-cubic. Impuphu ye-zirconia ezinzile noma ezinzile kancane ingatholakala ngokungeza amanani afanele eziqinisi (njenge-yttrium oxide kanye ne-calcium oxide), okuvumela ukuthi igcine ukuzinza kwesigaba okuhle kakhulu kanye nezakhiwo zemishini ngisho nasemazingeni okushisa aphezulu.
Impuphu yeZirconiaIzinzuzo ezivelele zika-'s zibonakala kakhulu kulezi zici ezilandelayo:
Ubulukhuni obuphezulu kanye nekhono elihle kakhulu lokupholisha: Ngobulukhuni be-Mohs obungu-8.5 noma ngaphezulu, bufanelekela ukupholisha kokugcina kwezinto ezahlukahlukene zokuqina okuphezulu.
Ukuqina kwamakhemikhali okuqinile: Kuhlala kuzinzile ezindaweni ezine-asidi noma ezine-alkaline kancane futhi akuthinteki ekuphenduleni kwamakhemikhali.
Ukusabalala Okuhle Kakhulu: Usayizi we-nano- noma we-submicron oguquliweizimpushana ze-zirconiazikhombisa ukumiswa okuhle kakhulu kanye nokugeleza kahle, okwenza kube lula ukupholisha okufanayo.
Ukushisa okuphansi kanye nomonakalo ophansi wokungqubuzana: Ukushisa okukhiqizwa ngesikhathi sokupholisha kuncane kakhulu, okunciphisa ngempumelelo ukucindezeleka kokushisa kanye nengozi yokuqhekeka okuncane ebusweni obucutshungulwayo.
II. Ukusetshenziswa Okuvamile Kwe-Zirconia Powder Ekupholisheni Okunembile
1. Ukupholisha I-Sapphire Substrate
Amakristalu e-sapphire, ngenxa yobulukhuni bawo obuphezulu kanye nezakhiwo ezinhle kakhulu zokukhanya, asetshenziswa kabanzi kuma-chips e-LED, amalensi okubuka, kanye namadivayisi e-optoelectronic. I-Zirconia powder, enobulukhuni obufanayo kanye nesilinganiso somonakalo ophansi, iyinto efanelekile yokupholisha ngemishini yamakhemikhali (i-CMP) ye-sapphire. Uma kuqhathaniswa ne-othomathikhi yendabuko.izimpushana zokupholisha i-aluminium oxide, i-zirconia ithuthukisa kakhulu ukuthamba komphezulu kanye nokuphela kwesibuko ngenkathi igcina amazinga okususwa kwezinto, inciphisa imihuzuko kanye nemifantu emincane.
2. Ukupholisha Ingilazi Ebonakalayo
Ekucutshungulweni kwezingxenye ezibonakalayo ezifana namalensi anembile kakhulu, ama-prism, kanye nobuso be-fiber ye-optical, izinto zokupholisha kumele zihlangabezane nezidingo zokuhlanzeka okuphezulu kakhulu kanye nokucwebezela. Ukusebenzisa ubumsulwa obuphezului-zirconium oxide powderenosayizi wezinhlayiya olawulwayo ongu-0.3-0.8 μm njenge-ejenti yokugcina yokupholisha ifinyelela ubulukhuni bomphezulu obuphansi kakhulu (Ra ≤ 1 nm), ihlangabezana nezidingo "ezingenaphutha" eziqinile zamadivayisi optical.
3. Ukucubungula i-Hard Drive Platter kanye ne-Silicon Wafer
Njengoba ukwanda okuqhubekayo kobuningi besitoreji sedatha, izidingo zokuba yisicaba kobuso be-hard drive ziya ngokuya ziba nzima.Impuphu yeZirconia, esetshenziswa esigabeni sokupholisha kahle izindawo zeplati ye-hard drive, ilawula ngempumelelo amaphutha okucubungula, ithuthukisa ukusebenza kahle kokubhala kwediski kanye nokuphila kwesevisi. Ngaphezu kwalokho, ekupholiseni okunembe kakhulu kwama-silicon wafers, i-zirconium oxide ibonisa ukuhambisana okuhle kakhulu kwendawo kanye nezakhiwo zokulahlekelwa okuphansi, okwenza kube yindlela ekhulayo esikhundleni se-ceria.
Ⅲ. Umphumela Wobukhulu Bezinhlayiyana Nokulawulwa Kokuhlakazeka Emiphumeleni Yokupholisha
Ukusebenza kokupholisha kwe-zirconium oxide powder kuhlobene eduze hhayi nje nobunzima bayo obubonakalayo kanye nesakhiwo sekristalu, kodwa futhi kuthonywa kakhulu ukusatshalaliswa kosayizi wezinhlayiya zayo kanye nokuhlakazeka kwayo.
Ukulawulwa Kosayizi Wezinhlayiya: Ubukhulu bezinhlayiya obukhulu kakhulu bungabangela kalula imihuzuko ebusweni, kanti ubuncane kakhulu bunganciphisa amazinga okususwa kwezinto. Ngakho-ke, izinhlayiya ezincane noma izinhlayiya ezincane ezinobubanzi be-D50 obungu-0.2 kuya ku-1.0 μm zivame ukusetshenziselwa ukuhlangabezana nezidingo ezahlukene zokucubungula.
Ukusebenza Kokuhlakazeka: Ukuhlakazeka okuhle kuvimbela ukuhlangana kwezinhlayiya, kuqinisekisa ukuzinza kwesisombululo sokupholisha, futhi kuthuthukisa ukusebenza kahle kokucubungula. Ezinye izimpushana ze-zirconia ezisezingeni eliphezulu, ngemva kokuguqulwa kobuso, zibonisa izakhiwo ezinhle kakhulu zokumiswa ezixazululweni zamanzi noma ezibuthakathaka, zigcina ukusebenza okuzinzile amahora angaphezu kwamashumi amaningi.
IV. Izitayela Zentuthuko kanye Nombono Wesikhathi Esizayo
Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwenza izinto ezincane,izimpushana ze-zirconiaziyathuthukiswa zibe msulwa kakhulu, ukusatshalaliswa kosayizi wezinhlayiya okuncane, kanye nokusabalala okuthuthukisiwe. Izindawo ezilandelayo zidinga ukunakwa esikhathini esizayo:
1. Ukukhiqizwa Okukhulu kanye Nokuthuthukiswa Kwezindleko ze-Nano-ScaleIzimpushana zeZirconia
Ukubhekana nenqubo ebiza kakhulu neyinkimbinkimbi yokulungiselela izimpushana ezihlanzekile kakhulu kubalulekile ekukhuthazeni ukusetshenziswa kwazo kabanzi.
2. Ukuthuthukiswa Kwezinto Zokupholisha Ezihlanganisiwe
Ukuhlanganisa i-zirconia nezinto ezifana ne-alumina ne-silica kuthuthukisa amazinga okususa kanye namakhono okulawula ubuso.
3. Uhlelo Loketshezi Lokupholisha Oluluhlaza Nolungangcolisi Imvelo
Thuthukisa imithombo yokusabalala engenabo ubuthi, ebolayo kanye nezithasiselo ukuze kuthuthukiswe ubungane bemvelo.
V. Isiphetho
Impuphu ye-Zirconium oxide, ngezakhiwo zayo ezinhle kakhulu zezinto ezibonakalayo, idlala indima ebaluleke kakhulu ekupholisheni ngokunemba okuphezulu. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe bokukhiqiza kanye nesidingo esikhulayo semboni, ukusetshenziswa kwei-zirconium oxide powderkuzosabalala kakhulu, futhi kulindeleke ukuthi kube ukusekelwa okuyinhloko kwesizukulwane esilandelayo sezinto zokupholisha ezisebenza kahle kakhulu. Ezinkampanini ezifanele, ukuhambisana nezitayela zokuthuthukisa izinto kanye nokwandisa izinhlelo zokusebenza eziphezulu emkhakheni wokupholisha kuzoba yindlela ebalulekile yokufeza ukuhlukaniswa komkhiqizo kanye nobuholi bezobuchwepheshe.
