Ukutyhila iSayensi engasemva kweCerium Oxide: Indlela Efikelela Ngayo Ukugqibelela Komphezulu We-Atomic
Kwicandelo lemveliso yanamhlanje echanekileyo, ukufikelela kumphezulu weglasi ogudileyo kakhulu kubalulekile ekuqinisekiseni ukusebenza kakuhle kokukhanya. Eyona nto iphambili kule nkqubo yi-cerium oxide (CeO₂) polishing powder[1], into engundoqo engenakutshintshwa yokupolisha iglasi ekumgangatho ophezulu, exatyiswa ngenxa yeempawu zayo ezikhethekileyo. Ukubaluleka kwayo akupheleli nje ekusebenzeni kwayo kakuhle kokupolisha kodwa nakubuchule bayo bokufikelela ekuchanekeni komphezulu we-nanoscale, ihambelana neemfuno zobugcisa ezingqongqo ukusuka kwiglasi eqhelekileyo ethe tyaba ukuya kwiilensi ze-aerospace optical.
Imigaqo Yesayensi: Indlela iCerium Oxide Enceda Ngayo Ukususwa Kwezinto Ezikwinqanaba Leathomu
Ubuhle be-cerium oxide polishing powder buvela kwiimpawu zayo ezahlukeneyo ze-physicochemical. Ngokwemvelo, i-cerium oxide powder esemgangathweni ophezulu inomlinganiselo ofanayo we-sub-micron particle distribution (ngesiqhelo ene-D50 ekuluhlu lwe-0.3-1.5μm) kunye nobunzima obuphezulu (malunga ne-7 kwisikali se-Mohs). Le propati yolwakhiwo ivumela ukuba ivelise amawaka ezigidi zee-micro-cutting points ngexesha lenkqubo yokupolisha, okwenza kube lula ukukrala komphezulu weglasi.
Eyona nto ibalulekileyo kukuba, indlela yayo yokupolisha iikhemikhali ibandakanya ukwakheka komaleko wenguqu ngokusebenzisa i-Ce-O-Si chemical bonding phakathi kwe-cerium oxide kunye nomphezulu weglasi ye-silicate phantsi koxinzelelo kunye nokungqubana. Lo maleko wenguqu uqhubeka uveliswa kwaye ususwa ngokucheba oomatshini, nto leyo efezekisa ukususwa kwezinto kwinqanaba le-athomu. Lo msebenzi wentsebenziswano phakathi kweekhemikhali noomatshini ukhokelela kumazinga aphezulu okususwa kwezinto kunye nomonakalo ophantsi womphezulu xa kuthelekiswa nokupolisha oomatshini okucocekileyo.
Ukusebenza koBugcisa: Ukulinganisa Umgangatho wePowder yokuPolisha iCerium Oxide
Izalathisi zobugcisa eziphambili zokuvavanya umgubo wokupholisha we-cerium oxide zenza inkqubo egqibeleleyo yomgangatho:
Umxholo weRare Earth Oxide (REO) kunye neCerium Oxide Purity: Iipowders zokupholisha eziphezulu kufuneka zibe ne-REO ≥ 90%, ukuqinisekisa ukuhambelana kunye nokuzinza kweempendulo zeekhemikhali zokupholisha.
Ukusasazwa koBukhulu beeNgcambu: i-D50 (ubukhulu obuphakathi beengcambu) kunye ne-D90 (ubukhulu beengcambu apho i-90% yeengcambu ifumaneka khona) kunye zimisela ukuchaneka kokupholisha; ukuze kupholise ngokubonakalayo okuchanekileyo, i-D50 ≤ 0.5μm kunye ne-D90 ≤ 2.5μm ziyafuneka, nto leyo ebonisa ukusasazwa kobukhulu obuncinci.
Uzinzo Lokumiswa: Iimveliso ezisemgangathweni kufuneka zigcine ukumiswa okuzinzileyo imizuzu engama-60-80 kwisisombululo sokupholisha ukuze kuthintelwe ukupholisha okungalinganiyo ngenxa yokungcola.
Ezi zibonakaliso xa zizonke zenza imodeli yovavanyo lokusebenza komgubo wokupholisha we-ceria, zichaphazela ngokuthe ngqo iziphumo zokugqibela zokupholisha.
Imbonakalo Yesicelo: Ukusuka Kwiglasi Yemihla Ngemihla ukuya KwiTekhnoloji Ephambili
Ubuchwepheshe bokupholisha i-cerium oxide bungene kwiinkalo ezininzi zoshishino zanamhlanje:
Imizi-mveliso yokubonisa kunye ne-Optoelectronic: Yinto ephambili esetyenziswayo ekupolisheni iglasi eqhubayo ye-ITO, iglasi egqumayo ebhityileyo kakhulu, kunye neephaneli zokubonisa zekristale yolwelo, ukuze ifikelele kuburhabaxa obungaphantsi kwe-nanometer ngaphandle kokonakalisa ifilimu ye-ITO.
Izixhobo Zokukhanya: Isetyenziswa ekucutshungulweni kwezinto ezahlukeneyo ezifana neelensi, iiprism, kunye nezihluzi ze-optical, i-cerium Oxide ifanelekile ngokukodwa ekupolisheni ngokuchanekileyo kweglasi ekhethekileyo ye-optical, njengeglasi ye-flint, inciphisa ixesha lokupolisha ngama-40%-60%.
Ukwenziwa kweZixhobo eziPhezulu: Kwimveliso yezinto ezibonakalayo ezichanekileyo kakhulu ezifana nee-semiconductor silicon wafers, iifestile zokujonga i-spacecraft, kunye nezibuko ze-laser gyroscope, i-nano cerium oxide ecocekileyo kakhulu (ubumsulwa ≥ 99.99%, ubungakanani bezinto ezincinci ≤ 0.3μm) inokufikelela kwi-atomic-level flatness surface.
Ukucubungula izinto zokuhombisa nezobuGcisa: Isetyenziswa ekuphatheni izinto zodidi oluphezulu ezifana namatye anqabileyo okwenziwa, izinto zobugcisa zekristale, kunye neewotshi ezikumgangatho ophezulu, inika iziphumo ezibonakalayo ezingenamikrwelo nezicacileyo.
Ukususela ekukhanyeni okucacileyo kwezikrini ze-smartphone ukuya ekuchanekeni okugqithisileyo kweelensi zeteleskopu zesithuba, i-cerium oxide polishing powder ifikelele kwinkqubela phambili ebalulekileyo kumava okubona abantu ngomsebenzi wayo kwihlabathi le-microscopic. Le teknoloji, edibanisa isayensi yezinto, i-interface chemistry, kunye ne-precision mechanics, iyaqhubeka nokunyusa imida yonyango lomphezulu weglasi. Unxibelelwano ngalunye lwe-microscopic ngexesha lenkqubo yokupolisha lubonisa indlela iimpawu zendalo zezinto ezinokuguqulwa ngayo zibe ngamandla atshintsha umbono wethu.
