Iterambere ryihuse mubijyanye namakuru na optoelectronics ryateje imbere ivugurura rihoraho rya tekinoroji ya mashini (CMP).Usibye ibikoresho nibikoresho, kugura hejuru ya ultra-high-precision surface biterwa cyane nigishushanyo mbonera n’umusaruro w’inganda zikora neza cyane, ndetse no gutegura ibishishwa bikwiranye.Hamwe nogukomeza kunoza uburyo bwo gutunganya neza neza nibisabwa neza, ibisabwa kubikoresho byohanagura neza nabyo biragenda byiyongera.Derixyde ya Cerium yakoreshejwe cyane mugutunganya neza ibikoresho bya microelectronic nibikoresho bya optique.
Ifu ya Cerium oxyde (VK-Ce01) ifu ya polishinge ifite ibyiza byo gukata gukomeye, gukora neza cyane, gusya neza, neza neza neza, ibidukikije bikora neza, umwanda muke, ubuzima bwa serivisi ndende, nibindi, kandi bikoreshwa cyane muri optique isobanutse neza na CMP, nibindi umurima ufite umwanya wingenzi cyane.
Ibintu by'ibanze bya cerium oxyde:
Ceria, izwi kandi nka cerium oxyde, ni oxyde ya cerium.Muri iki gihe, agaciro ka cerium ni +4, naho imiti yimiti ni CeO2.Ibicuruzwa byera ni ifu iremereye cyangwa ifu ya kirisiti, kandi ibicuruzwa byanduye ni umuhondo wijimye cyangwa se ibara ryijimye kugeza ifu yijimye-yijimye (kuko irimo urugero rwa lanthanum, praseodymium, nibindi).Ku bushyuhe bwicyumba nigitutu, ceria ni oxyde ihamye ya cerium.Cerium irashobora kandi gukora +3 valence Ce2O3, idahindagurika kandi izakora CeO2 ihamye hamwe na O2.Cerium oxyde irashonga gato mumazi, alkali na aside.Ubucucike ni 7.132 g / cm3, aho gushonga ni 2600 ℃, naho guteka ni 3500 ℃.
Uburyo bwo gusya bwa cerium oxyde
Ubukomezi bwa CeO2 ntabwo buri hejuru.Nkuko bigaragara mu mbonerahamwe ikurikira, ubukana bwa oxyde cerium buri munsi cyane ugereranije na diyama na oxyde ya aluminium, kandi ikanaba munsi ya oxyde ya zirconium na oxyde silicon, ihwanye na oxyde ferric.Ntabwo rero bishoboka muburyo bwa tekiniki gukuraho ibikoresho bishingiye kuri silicon oxyde, nkibirahuri bya silikatike, ikirahuri cya quartz, nibindi, hamwe na ceria ifite ubukana buke uhereye kumashini gusa.Nyamara, cerium oxyde kuri ubu niyo ifu yifu ya polishinge yo gusiga ibikoresho bya silicon oxyde cyangwa ibikoresho bya nitride ya silicon.Birashobora kugaragara ko polieri ya cerium nayo ifite izindi ngaruka usibye ingaruka zumukanishi.Ubukomezi bwa diyama, bukunze gukoreshwa mu gusya no gusya, ubusanzwe bufite imyanya ya ogisijeni muri kasike ya CeO2, ihindura imiterere yumubiri n’imiti kandi ikagira ingaruka runaka kumiterere.Ubusanzwe ikoreshwa rya cerium oxyde isize ifu irimo umubare munini wizindi oxyde idasanzwe.Okiside ya Praseodymium (Pr6O11) ifite kandi imiterere yububiko bwa cubic lattice, ikwiranye no gusya, mugihe izindi oxyde ya lanthanide idasanzwe idafite ubushobozi bwo gusya.Hatabayeho guhindura imiterere ya kristu ya CeO2, irashobora gukora igisubizo gihamye hamwe nayo murwego runaka.Kuri porojeri nini ya nano-cerium oxyde (VK-Ce01), niko ubuziranenge bwa okiside ya cerium (VK-Ce01), niko ubushobozi bwo gusya hamwe nubuzima bumara igihe kirekire, cyane cyane kubirahuri bikomeye na lens ya optique kuri a igihe kirekire.Iyo guswera cyclic, ni byiza gukoresha ifu ya cerium oxyde isukuye cyane (VK-Ce01).
Gukoresha ifu ya cerium oxyde:
Ifu ya Cerium oxyde (VK-Ce01), ikoreshwa cyane cyane mu gusya ibirahuri, ikoreshwa cyane mubice bikurikira:
1. Amadarubindi, ibirahuri by'ibirahure;
2. Lens optique, ikirahure cya optique, lens, nibindi.;
3. Terefone igendanwa ya terefone igendanwa, kureba hejuru (kureba umuryango), nibindi.;
4. LCD ikurikirana ubwoko bwose bwa ecran ya LCD;
5. Rhinestone, diyama ishyushye (amakarita, diyama kuri jeans), imipira yaka (chandeliers nziza muri salle nini);
6. Ubukorikori bwa kirisiti;
7. Kuringaniza igice cya jade
Ibikomoka kuri cerium oxyde ikomokaho:
Ubuso bwa cerium oxyde yometse kuri aluminiyumu kugirango itezimbere cyane ikirahure cya optique.
Ishami ryubushakashatsi niterambere ryiterambere rya UrbanMines Tech.Bidafite aho bihuriye, byasabye ko guhuza no guhindura ibice bya polishinge aribwo buryo nyamukuru nuburyo bwo kunoza imikorere nukuri kwa CMP.Kuberako ibice bigize ibice bishobora guhuzwa no guhuza ibintu byinshi bigize ibice, kandi gutatanya gukwirakwira hamwe no gutunganya neza imikorere ya polishinge birashobora kunozwa no guhindura ubuso.Gutegura no gusya imikorere yifu ya CeO2 yometse kuri TiO2 irashobora kuzamura imikorere ya polish hejuru ya 50%, kandi mugihe kimwe, inenge zo hejuru nazo zigabanukaho 80%.Ingaruka zo guhuza imbaraga za CeO2 ZrO2 na SiO2 2CeO2 ya oxyde;kubwibyo rero, tekinoroji yo gutegura dopiya ceria micro-nano compite oxyde ifite akamaro kanini mugutezimbere ibikoresho bishya byo gusya no kuganira kuburyo bwo gusya.Usibye umubare wa doping, leta nogukwirakwiza dopant mubice bya synthesize nabyo bigira ingaruka cyane kumiterere yabyo no mumikorere ya polishing.
Muri byo, synthesis yo gusya ibice bifite imiterere yambaye neza birashimishije.Kubwibyo, guhitamo uburyo bwubukorikori nuburyo bukenewe nabyo ni ngombwa cyane, cyane cyane ubwo buryo bworoshye kandi buhendutse.Gukoresha karubone ya hydratiya ya hydrata nkibikoresho byingenzi, aluminium-dope cerium oxyde polishing ibice byashizwemo nuburyo bukomeye bwa fonctionnement ya chimique.Hifashishijwe imbaraga za mashini, ibice binini bya karubone ya cerium hydrated irashobora gushyirwamo ibice byiza, mugihe nitrate ya aluminium ikora namazi ya amoniya kugirango ibe amorphous colloidal.Ibice bya colloidal bifatanye byoroshye na cerium karubone, hanyuma nyuma yo gukama no kubara, doping ya aluminiyumu irashobora kugerwaho hejuru ya oxyde cerium.Ubu buryo bwakoreshejwe mugushushanya ibice bya cerium oxyde hamwe na doping ya aluminiyumu itandukanye, kandi imikorere yabyo yo kurasa yaranzwe.Nyuma yumubare ukwiye wa aluminiyumu wongeyeho hejuru yubutaka bwa cerium oxyde, agaciro keza k'ubushobozi bwo hejuru kariyongera, ari nako byatumye habaho itandukaniro riri hagati yuduce duto duto.Hariho imbaraga za electrostatike yanga, iteza imbere kunoza ihagarikwa ryimikorere.Muri icyo gihe, imikoranire ya adsorption hagati yuduce duto duto kandi tworoheje tworoheje binyuze muri Coulomb ikurura nayo izashimangirwa, ibyo bikaba ari ingirakamaro mu mikoranire hagati y’ibintu byangiza kandi byoroshye hejuru yikirahure gisennye, kandi bigateza imbere kunoza igipimo cyo gusya.
