Kev loj hlob sai ntawm cov teb cov ntaub ntawv thiab Optoelectronics tau nce qib kev hloov kho ntawm cov tshuaj kho tshuab polishing (CMP). Ntxiv rau cov khoom siv thiab cov ntaub ntawv, kev nrhiav tau ntawm ultra-siab-precision chaw muaj ntau ntawm cov kev ua kom siab, nrog rau kev npaj ntawm cov sib piv ntawm cov slurry. Thiab nrog kev txhim kho txuas ntxiv ntawm kev ua haujlwm nto cuam uas yog qhov tseeb thiab kev ua tau zoo, cov cai ua haujlwm kom muaj zog cov ntaub ntawv tau nce siab dua thiab siab dua. Cerium dioxide tau siv dav hauv qhov chaw precision ntawm cov khoom siv microeltronic siv thiab precision kho qhov muag.
CERACE Oxide Polishing Hmoov (VK-CE01) POLISHING FORCISTION, thiab lwm yam kev ua haujlwm ntev, thiab lwm yam teb tau ua haujlwm ib txoj haujlwm tseem ceeb heev.
Cov Khoom Yooj Yim ntawm Ciab Oxide:
Ceria, tseem hu ua Cinex oxide, yog oxide ntawm cerium. Nyob rau lub sijhawm no, lub peev xwm ntawm cerium yog +4, thiab tshuaj mis mis yog CEO2. Cov khoom ntshiab yog cov hmoov hnyav lossis cubic crystal, thiab cov hmoov dawb paug lossis cov xim liab dawb (vim tias nws muaj cov kab ntawm Lanthhanum, Prease Cleamum, PreaseYMACI, thiab lwm yam). Nyob rau hauv chav tsev kub thiab siab, ceria yog cov oxide ruaj khov ntawm cerium. Cerium tseem tuaj yeem tsim +3 Qhov tseem ceeb CE2O3, uas yog tsis ruaj khov thiab yuav tsim ua CEO2 ruaj khov nrog O2. Creium ox oxide yog soluble me ntsis hauv dej, alkali thiab acid. Qhov ceev yog 7.132 g / cm3, lub po melting point yog 2600 ℃, thiab lub boiling point yog 3500 ℃.
Polishing Txheej Txheem Ntawm Creium Oxide
Lub hardness ntawm CEO2 hais yog tsis siab. Raws li qhia hauv cov lus hauv qab no, lub hardness ntawm Creium oxide yog qhov qis dua uas ntawm zirconium oxide, thiab kuj yog qis dua li ntawm zircon oxide, uas yog sib npaug rau ferric oxide. Nws yog yog li tsis muaj cov thev naus laus zis ua rau depolish silicon oxide cov ntaub ntawv, xws li cov iav sileve, quartz iav, thiab lwm yam. Txawm li cas los xij, cerium oxide yog tam sim no cov hmoov polishing hmoov rau polishing silicon oxide-based cov ntaub ntawv lossis txawm tias silicon nitride cov ntaub ntawv. Nws tuaj yeem pom tau tias cerium oxish polishing tseem muaj lwm cov txiaj ntsig dhau ntawm cov neeg siv khoom. Lub hardness ntawm pob zeb diamond, uas yog cov khoom siv sib tsoo thiab cov khoom siv polygen, uas hloov pauv nws lub cev thiab tshuaj lom neeg thiab muaj qee yam cuam tshuam rau cov khoom sib dhos. Feem ntau siv cerium oxide polishing fwj muaj qee tus nqi ntawm lwm lub ntiaj teb tsis tshua muaj txiaj ntsig oxides. Cov roj ntsha olidymium (PR6O11) tseem muaj lub ntsej muag zoo nkauj lotuav tus qauv ua ke, uas yog qhov tsim nyog rau polishing, thaum lwm txoj kev tsis tshua muaj peev xwm tsis muaj lub peev xwm polishing. Tsis muaj kev hloov cov qauv siv lead ua ntawm CEO2, nws tuaj yeem tsim cov tshuaj khov kho nrog nws hauv qee qhov ntau. Rau siab-dawb huv-cerium oxide polishing hmoov (vk-ce Thaum syclic polishing, nws raug nquahu kom siv high-purity cerium oxide polishing hmoov (vk-pes-CE01).
Daim Ntawv Thov Kev Ca Ciab Oxide Polishing Hmoov:
CERACE Oxide Polishing Hmoov (Vk-Qu01), tsuas yog siv rau cov khoom lag luam thiab cov khoom lag luam hauv qab no:
1. Tsom iav, iav lens polishing;
2. Optical lens, iav kho qhov muag kho tshiab, lens, thiab lwm yam .;
3. Txawb xov tooj xov tooj ntawm tes iav, saib saum npoo (saib lub qhov rooj), thiab lwm yam .;
4. LCD Saib Xyuas Txhua Yam ntawm LCD Screen;
5. Rhinestones, kub pob zeb diamond (phaib, Diamonds ntawm ris ntauv txhav), teeb pom kev zoo pob (cov chandeliers nyob hauv chav loj);
6. Cov khoom siv crystal;
7. Ib nrab polishing ntawm jade
Tam sim no Cine cerium oxide polishing derivatives:
Cov saum npoo ntawm cerium oxide yog doped nrog txhuas kom txhim kho nws polishing ntawm iav kho qhov muag.
Kev Tshawb Fawb Technology thiab Kev Txhawb Kev Txhawb Kev Txhawb Kev Cenburanmines Tech. Txwv, thov kom cov compounding thiab NTO kev hloov kho ntawm polishing hais yog cov txheej txheem tseem ceeb thiab cov hau kev los txhim kho kev ua haujlwm tau zoo thiab raug ntawm cmp polishing. Vim hais tias cov khoom siv particle tuaj yeem raug tuned los ntawm ntau cov ntsiab lus, thiab cov dispersion ruaj khov thiab polishing kev ua tau zoo thiab ua polishing kev ua tau zoo los ntawm kev hloov kho saum npoo. Qhov kev npaj thiab polishing kev ua tau ntawm caso2 hmoov doped nrog tio2 tuaj yeem txhim kho kev sib deev los ntawm ntau dua 50%, thiab tib lub sijhawm, cov khoom tsis xws li yog txo 80%. Lub synerocistic polishing cuam tshuam ntawm CEO2 ZRO2 thiab Sio2 2CEO2 Composite oxides; Yog li ntawd, kev npaj thev naus laus zis ntawm doped ceria micro composite oxides yog qhov tseem ceeb ntawm kev txhim kho cov ntaub ntawv tshiab thiab kev sib tham ntawm polishing mechanism. Ntxiv nrog rau Doping tus nqi, lub xeev thiab faib cov dopant hauv synthesized hais kuj cuam tshuam lawv cov khoom thiab polishing.
Ntawm lawv, cov synthesis ntawm polishing hais nrog cov qauv cladding yog qhov txaus nyiam dua. Yog li ntawd, xaiv cov qauv hluavtaws thiab cov xwm txheej tseem ceeb heev, tshwj xeeb tshaj yog cov hau kev uas yooj yim thiab siv tau. Siv hydrated cerium carbonate yog cov khoom siv rawin aluminium yog cov khoom ntub tau synthesized los ntawm ntub dej-pase kiv cua tshuab. Nyob rau hauv qhov kev txiav txim ntawm kev ua haujlwm ntawm cov tshuab hluav taws xob, cov khoom loj ntawm hydrated cerium carbonate tuaj yeem ua rau cov khoom zoo, thaum txhuas cov dej kom tsim cov amorphous colloidal hais. Cov lus colloidal tau yooj yim txuas nrog cerium carbonate hais, thiab tom qab ziab thiab doping, Aluminium doping tuaj yeem ua tiav ntawm cov npoo ntawm Creium oxide. Cov qauv no tau siv los ua cov hluavtaws cerium oxide hais nrog cov sib txawv ntawm txhuas doping, thiab lawv polishing ua tau zoo. Tom qab ib qho txiaj ntsig tsim nyog ntawm txhuas tau ntxiv rau saum npoo ntawm CERINE OXIDE tus nqi yuav nce ntxiv, uas nyeg ua tau qhov sib txawv ntawm cov abrasive hais. Muaj lub zog electrostatic repulsion, uas txhawb kev txhim kho cov kev txhim kho kom tsis meej. Nyob rau tib lub sijhawm, kev sib nrig sib pab ntawm cov txheej txheem abrasive thiab cov txheej txheem zoo rau cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem polished ntawm cov kev txhim kho ntawm cov txheej txheem polished, thiab txhawb nqa kev txhim kho ntawm cov polishing tus nqi.
