Kufumura Sainzi Iri Kuseri kweCerium Oxide: Maitiro Ainoita Kuti Nzvimbo Ive Yakanaka Zvikuru
Muchikamu chemazuva ano chekugadzira zvinhu nemazvo, kuwana nzvimbo dzegirazi dzakapfava zvakanyanya kwakakosha pakuona kuti optical inoshanda zvakanaka. Pakati peizvi pane cerium oxide (CeO₂) polishing powder[1], chinhu chakakosha chisingatsiviwi chekupukuta magirazi emhando yepamusoro, chinokosheswa nekuda kwehunhu hwacho hwakasiyana. Kukosha kwayo hakusi chete mukushanda kwayo kwakanaka kwekupukuta asiwo mukukwanisa kwayo kuwana nanoscale surface precision, zvichienderana nezvinodiwa zvehunyanzvi kubva kugirazi rakajairika kusvika kumalenzi emagetsi emuchadenga.
Nheyo dzeSainzi: Maitiro Ekuti Cerium Oxide Ibvise Zvinhu Padanho reAtomu
Kubudirira kwe cerium oxide polishing powder kunobva muhunhu hwayo hwakasiyana hwe physicochemical. Panyama, cerium oxide powder yemhando yepamusoro ine saizi yakafanana ye sub-micron particles (kazhinji ine D50 iri pakati pe 0.3-1.5μm) uye kuomarara kwakanyanya (inenge 7 paMohs scale). Hunhu uhwu hwekuvaka hunoibvumira kugadzira mabhiriyoni e micro-cutting points panguva yekupukuta, zvichiita kuti girazi rikwanise kukwenya zvakanyanya.
Chinokosha ndechekuti, nzira yayo yekupukuta makemikari inosanganisira kuumbwa kwechikamu chekuchinja kuburikidza neCe-O-Si chemical bonding pakati pecerium oxide nepamusoro pegirazi resilicate pasi pekumanikidzwa nekukweshana. Chikamu ichi chekuchinja chinoramba chichigadzirwa uye chichibviswa kuburikidza nekuchekwa kwemechanical, zvichiita kuti zvinhu zvibviswe paatomu. Ichi chiito chekubatana kwemechanical-chemical chinoita kuti zvinhu zvibviswe zvakanyanya uye kukuvara kwepamusoro kushoma zvichienzaniswa nekupukuta kwemechanical pure.
Kushanda Kwehunyanzvi: Kuyera Hunhu hweCerium Oxide Polishing Powder
Zviratidzo zvikuru zvehunyanzvi zvekuongorora upfu hwekupukuta hwecerium oxide zvinoumba sisitimu yakazara yemhando yepamusoro:
Rare Earth Oxide (REO) Content uye Cerium Oxide Purity: Upfu hwekupukuta hwemhando yepamusoro hunofanira kunge huine REO ≥ 90%, zvichiita kuti makemikari ekupukuta agare akasimba uye akasimba.
Kugoverwa kweSaizi yeZvidimbu: D50 (hukuru hwepakati hwezvidimbu) uye D90 (hukuru hwezvidimbu hunowanikwa 90% yezvidimbu) pamwe chete zvinosarudza kunyatsojeka kwekukwesha; pakukwesha kwemaziso kwakanyatsojeka, D50 ≤ 0.5μm uye D90 ≤ 2.5μm zvinodiwa, zvichiratidza kugoverwa kwehukuru hwakatetepa.
Kugadzikana Kwekusungirirwa: Zvigadzirwa zvemhando yepamusoro zvinofanirwa kuchengetedza kusungirirwa kwakasimba kwemaminitsi makumi matanhatu kusvika makumi masere mumushonga wekupukuta kudzivirira kupenya kusina kuenzana nekuda kwekudonha kwevhu.
Zviratidzo izvi pamwe chete zvinoumba modhi yekuongorora mashandiro eupfu hwekupukuta hweceria, zvichikanganisa zvakananga mhedzisiro yekupukuta kwekupedzisira.
Nzvimbo Yekushandisa: Kubva paGirazi Rezuva Nezuva kusvika paTekinoroji Yemazuva Ano
Tekinoroji yekupukuta oxide yeCerium yakapinda muminda yakawanda yemazuva ano yemaindasitiri:
Maindasitiri eDisplay neOptoelectronic: Inoshandiswa pakupukuta magirazi eITO, magirazi ekuvhara akatetepa kwazvo, uye mapaneru ekuratidza emvura ecrystal, zvichiita kuti firimu reITO rive rakaomarara pasina kukuvadza firimu racho.
Zvishandiso Zvemaziso: Inoshandiswa mukugadzirisa zvinhu zvakasiyana-siyana zvakaita semalenzi, maprism, uye mafirita emaziso, cerium Oxide inonyanya kukodzera kupukuta magirazi emaziso chaiwo, akadai segirazi reflint, zvichideredza nguva yekupukuta ne40%-60%.
Kugadzira Zvishandiso Zvemhando Yepamusoro: Mukugadzirwa kwezvinhu zvinopenya zvine hungwaru zvakaita sema "semiconductor silicon wafers", mahwindo ekuongorora spacecraft, uye magirazi e "laser gyroscope", nanocerium oxide ine hungwaru hwakanyanya (hungwaru ≥ 99.99%, saizi ye "particle" ≤ 0.3μm) inogona kuita kuti pamusoro payo pave ne "atomic-level flatness".
Kushongedza Uye Kugadzira Unyanzvi: Inoshandiswa pakugadzirisa pamusoro pezvinhu zveumbozha zvakaita sematombo anokosha ekugadzira, hunyanzvi hwekristaro, uye mawachi emhando yepamusoro, inopa mhedzisiro yekuona isina kukwenywa uye yakajeka.
Kubva pakupenya kwakajeka kwemasikirini emafoni kusvika pakunyatsojeka kwemalenzi emuchadenga ane telescope, cerium oxide polishing powder yabudirira zvikuru mukuona kwevanhu kuburikidza nebasa rayo munyika ine microscopic. Iyi tekinoroji, iyo inosanganisa sainzi yezvinhu, interface chemistry, uye precision mechanics, inoramba ichisimudzira miganhu yekurapa pamusoro pegirazi. Kubatana kwega kwega kwe microscopic panguva yekupukuta kunoratidza kuti hunhu hwechisikigo hwechinhu hunogona kushandurwa sei kuita simba rinoshandura maonero edu.
