Ukuthuthuka okusheshayo emikhakheni yolwazi kanye ne-opoleelectronics kukhuthaze ukubuyekezwa okuqhubekayo kobuchwepheshe be-Chemical Mechanic Polishing Polishing Polishical Polishical Polishing (CMP). Ngaphezu kwemishini nezinto zokwakha, ukutholwa kwezindawo eziphakeme ze-Ultra-high ngokunemba kuncike kakhulu ekwakhiweni nasekukhiqizweni kwezimboni okusebenza kahle kwezinhlayiya ezivumayo, kanye nokulungiselela kwe-slurry ehambisanayo. Futhi ngokwenza ngcono okuqhubekayo kokunemba kokunemba okungaphezulu nokusebenza kokusebenza kahle, izidingo zokusebenza kwezinto eziphilayo ezisebenza kahle nazo ziya ngokuya ziphakeme. I-Centium Dioxide isetshenziswe kabanzi ekubumbeni kwemishini okunembile kwamadivayisi ama-microelectronic kanye nokunemba okubonakalayo.
I-CERUEIUS OXIDE Polishing Powder (VK-CE01) I-Polishing Powder inezinzuzo zekhono eliqinile lokusika, ukusebenza kahle okuphezulu, ikhwalithi ephansi yokupholisa, impilo ephansi, futhi isetshenziswa kabanzi ku-Optical Perision Polishing ne-CMP, njll. Inkambu ithatha isikhundla esibaluleke kakhulu.
Izakhiwo eziyisisekelo ze-cerrium oxide:
UCouria, owaziwa nangokuthi i-certium oxide, uyinkabi ye-certuium. Ngalesi sikhathi, ubukhulu be-cerlium bungukuthi +4, futhi ifomula yamakhemikhali yi-CEO2. Umkhiqizo omsulwa yi-White Heave powder noma i-cubic crystal, futhi umkhiqizo ongcolile uphuzi ophuzi noma upinki ku-reddish-brown powder (ngoba uqukethe amanani e-lanthanum, ngoba aqukethe ama-lanthanum, i-prateodymium, njll.). Ekushiseni kwegumbi kanye nengcindezi, uCouria yi-oxium elizinzile le-certium. I-CERUUM ingakha futhi + 3 valence CE2O3, engazinzile futhi izokwakha i-CEA2 CEO2 eno-O2. I-Cerium Oxide incibilika kancane emanzini, i-alkali ne-acid. I-Density ingu-7.132 g / cm3, indawo yokuncibilika ingu-2600 ℃, futhi iphuzu elibilayo lingu-3500 ℃.
I-Polishing Mechanism of Cerrium Oxide
Ubulukhuni bezinhlayiya ze-CEOO2 aluphakeme. Njengoba kukhonjisiwe etafuleni elingezansi, ubulukhuni be-cerrium oxide buphansi kunaleya dayimane ne-aluminium oxide, futhi bephansi kunaleso se-zirconium oxide ne-silicon oxide, okulingana ne-ferric oxide. Ngakho-ke akunakwenzeka kwezobuchwepheshe kuma-disecon oxide asekelwe ezintweni, njengengilazi esibuyisana, ingilazi ye-quartz, njll. Kodwa-ke, i-certium oxide njengamanje ingumpuphu oncamelayo okhethwayo wokupholisha izinto ezisekelwe eSiliconi oxide noma izinsiza ze-silicon nitride. Kungabonakala ukuthi i-certium oxide polishing nayo ineminye imiphumela ngaphandle kwemiphumela emishini. Ubulukhuni bedayimane, elivame ukusetshenziswa kokugaya kanye nokuphola okuvame ukusetshenziswa, kuvame ukuba nezikhala ze-oksijini ku-CEO2 Lattice, eshintsha izakhiwo zayo ezingokomzimba nezamakhemikhali futhi inomthelela othile ekuboniseni izakhiwo. Ama-polishing we-certium oximane asetshenziswa kakhulu aqukethe inani elithile lamanye amazwe angavamile emhlabeni oxides. I-PraseOdymium Oxide (PR6O11) futhi inesakhiwo esigxile ebusweni se-cubic lattice, esilungele ukupolwilisa, kanti enye i-lanthanide Earth Earth oxides ayinawo amandla okuphola. Ngaphandle kokushintsha ukwakheka kwe-Crystal of CEO2, kungakha isixazululo esiqinile naso ngaphakathi kwebanga elithile. Okwe-Nano-Cereium oxide Polishing Powder (VK-CERE01), okuphezulu kwe-certuium oxide (VK-CE01), amandla amakhulu okuphola kanye nempilo yenkonzo enzima, ikakhulukazi i-hardz optical lens isikhathi eside. Lapho i-cyclic polishing, kungakuhle ukuthi usebenzise i-high purity cererity oxium oxide polishing powder (VK-CE01).
Ukusetshenziswa kwe-certium oxide polishing powder:
I-Cerium Oxide Polishing Powder (VK-CE01), esetshenziselwa ikakhulukazi imikhiqizo yengilazi yokupholisa, isetshenziswa ikakhulukazi kule mikhakha elandelayo:
1. Izibuko, i-lens lens lens;
2. I-lens ye-optical, ingilazi ye-optical, lens, njll;
I-3. Ingilazi yefoni yefoni ephathekayo, ukubukwa komhlaba (umnyango wokubuka), njll;
I-4. I-LCD qapha zonke izinhlobo zesikrini se-LCD;
Ama-Rhinestones, amadayimane ashisayo (amakhadi, amadayimane kuma-jean), amabhola okukhanyisa (ama-chandeliers okunethezeka ehholo elikhulu);
6. I-Crystal Crafts;
7. Ukudonswa okuyingxenye kwe-jade
I-Certium Oxiium Oxide Polishives:
Ingaphezulu le-certium oxide idonswa nge-aluminium ukuthuthukisa kakhulu ukucwaswa kwayo kwengilazi yamehlo.
Umnyango wezobuchwepheshe kanye noMnyango Wezentuthuko we-Urbanmines Tech. Okukhawulelwe, kuhlongozwa ukuthi ukuguqulwa okuhlanganisiwe nokubumba izinhlayiyana kwezimpawu zokuphola kuyizindlela eziphambili nezindlela zokwenza ngcono ukusebenza kahle nokunemba kwe-CMP polishing. Ngoba izakhiwo eziyizinhlayiyana zingahle zikhonkwane ngokuhlanganiswa kwezinto eziningi zezakhi, kanye nokuqina kokuhlakazeka kanye nokusebenza kokunye kokupholisha kuthuthukiswe ukuguqulwa komhlaba. Ukulungiswa kanye nokusebenza komoya opholile we-CEO2 i-Powder Doped nge-Tio2 kungathuthukisa ukusebenza kokuphoqelela ngaphezulu kwama-50%, futhi ngasikhathi sinye, kuncishiswa amaphutha angaphezulu. Umphumela wokuphamba okukhethekile we-CEO2 ZRO2 ne-SIO2 2CEO2 composite oxides; Ngakho-ke, ubuchwepheshe bokulungiselela be-ceria ceria micro-nano composite oxides bubaluleke kakhulu ekuthuthukisweni kwezinto ezintsha zokupholisha kanye nengxoxo ye-polishing mechanism. Ngaphezu kwenani le-doping, isimo kanye nokusatshalaliswa kweDopant ezinkithini ezihlanganisiwe nakho kuthinta kakhulu izakhiwo zazo ezingaphezulu kanye nokusebenza kokuphamba.
Phakathi kwazo, ukuhlanganiswa kwezinhlayiyana kwe-polishing ngesakhiwo sokuhlambalaza kukhanga ngokwengeziwe. Ngakho-ke, ukukhethwa kwezindlela zokwenziwa nezimo kubaluleke kakhulu, ikakhulukazi lezo zindlela ezilula futhi ezingenazindleko. Usebenzisa i-Certium Certium Carbonate njengezinto eziphambili eziluhlaza, izinhlayiya ze-aluminium-doped oxium oxium polishing zihlelwe yindlela ye-mechochemical esezingeni eliphansi. Ngaphansi kwesenzo samandla okusebenza, izinhlayiya ezinkulu ze-cellium carbonate carbonate zingagqekezwa zibe izinhlayiya ezinhle, ngenkathi i-aluminium nitrate ibhekana namanzi e-ammonia ukwakha izinhlayiya ze-colloidal ze-amonia. Izinhlayiya ze-colloidal zinamathiselwe kalula izinhlayiya ze-carbonate carbonate, futhi ngemuva kokomiswa nokuzoma, i-aluminium doping ingatholakala ebusweni be-certium oxide. Le ndlela yayisetshenziselwa ukuhlanganisa izinhlayiya ze-certium oxide ngamanani ahlukene we-aluminium doping, futhi ukusebenza kwawo kokuphoqelela kwabonakala. Ngemuva kokuthi inani elifanele le-aluminium lengezwe ebusweni bezinhlayiya ze-certium oxide oxide, inani elingelona iqiniso lamathuba angaphezulu lizokwanda, okuzokwenza igebe phakathi kwezinhlayiya ezinzima. Kukhona ukuthuthukiswa kwe-elektrostiki okunamandla, okukhuthaza ukuthuthuka kokuqina kokumiswa okuhlangene. Ngasikhathi sinye, i-adsorption ehambisanayo phakathi kwezinhlayiya ezi-abrasive kanye nongqimba oluthambile olukhokhiswayo nge-coulomb ahehayo futhi luzoqiniswa, oluzuzisa ukuxhumana phakathi kwengilazi ebunjiwe, futhi kuthuthukisa ukuphuculwa kwezinga lokuphamba.
