Uphando malunga nokusetyenziswa kweZirconia Powder kwiHigh-End Precision Polishing
Ngophuhliso olukhawulezileyo lwamashishini asebenza ngobuchwepheshe obuphezulu afana ne-elektroniki kunye netekhnoloji yolwazi, ukwenziwa kwezinto ezibonakalayo, ii-semiconductors, kunye neeseramikhi eziphambili, iimfuno eziphezulu zibekwe kumgangatho wokucubungula umphezulu wezinto ezibonakalayo. Ngokukodwa, kwi-machining echanekileyo kakhulu yezinto eziphambili ezifana ne-sapphire substrates, iglasi ebonakalayo, kunye nee-hard disk platters, ukusebenza kwezinto zokupolisha kumisela ngokuthe ngqo ukusebenza kakuhle kwe-machining kunye nomgangatho wokugqibela womphezulu.Umgubo weZirconia (ZrO₂), izinto ezingaphiliyo ezisebenza kakuhle, ziyavela kancinci kancinci kwicandelo lokupholisha ngokuchanekileyo ngenxa yobunzima bazo obugqwesileyo, ukuzinza kobushushu, ukumelana nokuguguleka, kunye neempawu zokupholisha, zibe ngummeli wesizukulwana esilandelayo sezinto zokupholisha emva kwe-cerium oxide kunye ne-aluminium oxide.
I. Iimpawu zezinto ezibonakalayoUmgubo weZirconia
I-Zirconia ngumgubo omhlophe onendawo yokunyibilika ephezulu (malunga ne-2700°C) kunye nezakhiwo ezahlukeneyo zekristale, kuquka ii-monoclinic, tetragonal, kunye ne-cubic phases. Umgubo we-zirconia ozinzileyo okanye ozinzileyo kancinci unokufumaneka ngokongeza ubungakanani obufanelekileyo bezinto ezizinzileyo (ezifana ne-yttrium oxide kunye ne-calcium oxide), okuvumela ukuba igcine uzinzo lwesigaba kunye neempawu zoomatshini ezintle nokuba kubushushu obuphezulu.
Umgubo weZirconiaIingenelo ezibalaseleyo zika-'s zibonakala kakhulu kwezi nkalo zilandelayo:
Ubunzima obuphezulu kunye nobuchule obuhle bokupholisha: Ngobunzima be-Mohs obuyi-8.5 nangaphezulu, ifanelekile ekupholiseni kokugqibela kwezixhobo ezahlukeneyo zobunzima obuphezulu.
Uzinzo oluqinileyo lweekhemikhali: Ihlala izinzile kwiindawo ezineasidi okanye ezine-alkaline kancinci kwaye ayinakuchaphazeleka ziikhemikhali.
Ukusasazeka okugqwesileyo: Ubungakanani be-nano- okanye i-submicron eguquliweyoiipowder ze-zirconiazinokumiswa kakuhle kunye nokuhamba kakuhle, nto leyo eyenza kube lula ukupolisha ngokulinganayo.
Ukuqhuba kobushushu obuphantsi kunye nomonakalo ophantsi wokungqubana: Ubushushu obuveliswayo ngexesha lokupolisha buncinci, nto leyo enciphisa ngempumelelo uxinzelelo lobushushu kunye nomngcipheko wokuqhekeka kwamaqhekeza amancinci kumphezulu ocutshungulwayo.
II. Ukusetyenziswa Okuqhelekileyo kweZirconia Powder kwiPrecision Polishing
1. Ukupholisha iSapphire Substrate
Iikristale zesafire, ngenxa yobunzima bazo obuphezulu kunye neempawu zazo ezibalaseleyo zokukhanya, zisetyenziswa kakhulu kwiitships ze-LED, iilensi zewotshi, kunye nezixhobo ze-optoelectronic. Umgubo weZirconia, onobunzima obufanayo kunye nesantya esiphantsi somonakalo, sisixhobo esifanelekileyo sokupolisha ngekhemikhali (CMP) yesafire. Xa kuthelekiswa nemveliiipowder zokupolisha i-aluminium oxide, i-zirconia iphucula kakhulu ukuthamba komphezulu kunye nokugqitywa kwesipili ngelixa igcina amazinga okususwa kwezinto, inciphisa imikrwelo kunye nemifantu emincinci.
2. Ukupolisha iglasi ebonakalayo
Xa kusetyenzwa izinto ezibonakalayo ezifana neelensi ezichanekileyo, iiprism, kunye nee-end fiber zobuso, izinto zokupolisha kufuneka zihlangabezane neemfuno zokucoceka okuphezulu kakhulu kunye nokuqina.umgubo we-zirconium oxideenobukhulu besuntswana olulawulwayo lwe-0.3-0.8 μm njenge-arhente yokugqibela yokupolisha ifikelela kuburhabaxa bomphezulu obuphantsi kakhulu (Ra ≤ 1 nm), ihlangabezana neemfuno ezingqongqo "ezingenasiphako" zezixhobo zokukhanya.
3. Iplati yeHard Drive kunye neSilicon Wafer Processing
Ngenxa yokwanda okuqhubekayo koxinano lokugcina idatha, iimfuno zokuba umphezulu weplati ye-hard drive ube buthathaka ziya zisiba nzima ngakumbi.Umgubo weZirconia, esetyenziswa kwinqanaba lokupholisha kakuhle kwiindawo zeplati ye-hard drive, ilawula ngokufanelekileyo iziphene zokucubungula, iphucula ukusebenza kakuhle kokubhala kwidiski kunye nobomi benkonzo. Ngaphezu koko, ekupholiseni ngokuchanekileyo kakhulu kwee-silicon wafers, i-zirconium oxide ibonisa ukuhambelana okuhle komphezulu kunye neempawu zokulahleka okuphantsi, okwenza ukuba ibe yindlela ekhulayo endaweni ye-ceria.
Ⅲ. Impembelelo yoBukhulu beeNgcawu kunye noLawulo lokuSasazwa kwiZiphumo zokuPolisha
Ukusebenza kokupholisha kwe-zirconium oxide powder kunxulumene ngokusondeleyo kungekuphela nje nobunzima bayo obubonakalayo kunye nesakhiwo sekristale, kodwa kukwachatshazelwa kakhulu kukusasazwa kwayo kunye nokusasazwa kwayo kobukhulu beesuntswana.
Ulawulo lobungakanani bamasuntswana: Ubukhulu obukhulu bamasuntswana bunokubangela imikrwelo yomphezulu ngokulula, ngelixa ubuncinci kakhulu bunokunciphisa amazinga okususwa kwezinto. Ke ngoko, ii-micropowders okanye ii-nanopowders ezinoluhlu lwe-D50 oluyi-0.2 ukuya kwi-1.0 μm zihlala zisetyenziselwa ukuhlangabezana neemfuno ezahlukeneyo zokucubungula.
Ukusebenza Kokusasazwa: Ukusasazeka kakuhle kuthintela ukuhlangana kwamasuntswana, kuqinisekisa uzinzo lwesisombululo sokupolisha, kwaye kuphucula ukusebenza kakuhle kokucubungula. Eminye imipuphu ye-zirconia ephezulu, emva kokuguqulwa komphezulu, ibonisa iimpawu ezintle zokumiswa kwizisombululo zamanzi okanye ezibuthathaka, zigcina ukusebenza okuzinzileyo kangangeeyure ezininzi.
