Lipatlisiso mabapi le Tšebeliso ea Powder ea Zirconia ka ho Pholisa ka mokhoa o nepahetseng ka ho fetisisa
Ka nts'etsopele e potlakileng ea liindasteri tsa theknoloji e phahameng joalo ka lisebelisoa tsa elektroniki le theknoloji ea tlhahisoleseling, tlhahiso ea optical, semiconductors, le lirafshoa tse tsoetseng pele, litlhoko tse phahameng li ntse li beoa boleng ba ts'ebetso ea thepa. Haholo-holo, machining a ultra-precision machining a likarolo tsa bohlokoa tse kang sapphire substrates, optical glass, le hard disk platters, ts'ebetso ea lisebelisoa tsa polishing e khetholla ka ho toba katleho ea machining le boleng ba ho qetela ba holim'a metsi.Zirconia phofo (ZrO₂), thepa e phahameng ea ts'ebetso e sa tloaelehang, butle-butle e hlaha tšimong ea ho belisoa ka mokhoa o nepahetseng ka ho fetisisa ka lebaka la ho thatafala ha eona, botsitso ba mocheso, ho hanyetsa ho roala, le thepa ea ho bentša, ho fetoha moemeli oa moloko o latelang oa lisebelisoa tsa ho bentša ka mor'a cerium oxide le aluminium oxide.
I. Lintho tse bonahalang tsaPhofo ea Zirconia
Zirconia ke phofo e tšoeu e nang le sebaka se phahameng sa ho qhibiliha (hoo e ka bang 2700 ° C) le mefuta e sa tšoaneng ea kristale, ho akarelletsa le monoclinic, tetragonal, le cubic phases. Zirconia phofo e tsitsitseng kapa e tsitsitseng ka mokhoa o itseng e ka fumanoa ka ho eketsa litekanyo tse nepahetseng tsa stabilizers (joaloka yttrium oxide le calcium oxide), e leng se lumellang ho boloka botsitso ba mohato o babatsehang le thepa ea mechine esita le mocheso o phahameng.
Zirconia phofo's melemo e hlaheletseng e bonahala haholo-holo likarolong tse latelang:
Boima bo phahameng le bokhoni bo babatsehang ba ho bentša: Ka boima ba Mohs ba 8.5 kapa ka holimo, bo loketse ho belisoa ha ho qetela ha mefuta e sa tšoaneng ea boima bo phahameng.
Botsitso bo matla ba lik'hemik'hale: E lula e tsitsitse tikolohong e nang le asiti kapa alkaline hanyenyane 'me ha e hlaselehe habonolo ke karabelo ea lik'hemik'hale.
Disspersibility e ntle haholo: E fetotsoe boholo ba nano- kapa submicronphofo ea zirconiabonts'a ho fanyeha ho hoholo le ho phalla, ho nolofatsa ho belisoa ha mokhoa o ts'oanang.
Ts'ebetso e tlase ea mocheso le tšenyo e fokolang ea likhohlano: Mocheso o hlahisoang nakong ea polishing o fokotsehile, o fokotsa ka katleho khatello ea mocheso le kotsi ea li-microcracks holim'a sebaka se sebetsitsoeng.
II. Lits'ebetso tse Tloaelehileng tsa Powder ea Zirconia ka ho hloekisoa ka mokhoa o nepahetseng
1. Sapphire Substrate polishing
Likristale tsa safire, ka lebaka la boima ba tsona bo phahameng le thepa e ntle ea mahlo, li sebelisoa haholo ho li-chips tsa LED, lilense tsa oache le lisebelisoa tsa optoelectronic. Phofo ea Zirconia, e nang le boima bo tšoanang le tekanyo e tlaase ea tšenyo, ke thepa e loketseng bakeng sa ho hloekisa lik'hemik'hale tsa lik'hemik'hale (CMP) tsa safire. Ha ho bapisoa le setsoaluminium oxide polishing powders, zirconia e ntlafatsa haholo holim'a flatness le ho qeta seipone ha e ntse e boloka litekanyetso tsa ho tlosoa ha thepa, ho fokotsa li-scratches le microcracks.
2. Optical Glass polishing
Ts'ebetsong ea likarolo tsa optical tse kang lilense tse nepahetseng haholo, li-prism le lifahleho tsa optical fiber, lisebelisoa tsa ho bentša li tlameha ho finyella litlhoko tse phahameng haholo tsa bohloeki le bohloeki. Ho sebelisa bohloeki bo phahamengzirconium oxide phofoe nang le karoloana e laoloang ea boholo ba 0.3-0.8 μm e le moemeli oa ho qetela oa ho bentša o finyella ho hlaba holimo haholo (Ra ≤ 1 nm), ho finyella litlhoko tse thata "tse se nang sekoli" tsa lisebelisoa tsa optical.
3. Hard Drive Platter le Silicon Wafer Processing
Ka keketseho e tsoelang pele ea boima ba polokelo ea data, litlhoko tsa hard drive platter surface flatness li ntse li eketseha ka thata.Zirconia phofo, e sebelisoang sethaleng se setle sa ho belisoa ha li-platter tsa hard drive, ka katleho e laola liphoso tsa ho sebetsa, ho ntlafatsa bokhoni ba ho ngola disk le bophelo ba tšebeletso. Ntle le moo, ha ho etsoa polishing e nepahetseng haholo ea li-wafers tsa silicon, zirconium oxide e bonts'a tšebelisano e ntle ea bokaholimo le thepa ea tahlehelo e tlase, e e etsa sebaka se seng se holang ho fapana le ceria.
Ⅲ. Phello ea Boholo ba Karolo le Taolo ea Phatlalatso ho Liphetho tsa ho Pholisa
Ts'ebetso ea ho bentsa ea phofo ea zirconium oxide e amana haufi-ufi eseng feela le boima ba 'mele le sebopeho sa kristale, empa hape e susumetsoa haholo ke kabo ea boholo ba likaroloana le ho hasana.
Taolo ea Boholo ba Particle: Boholo bo boholo bo feteletseng bo ka baka mengoallo habonolo, ha bo nyane haholo bo ka fokotsa litheko tsa ho tlosa thepa. Ka hona, li-micropowder kapa nanopowder tse nang le mefuta e mengata ea D50 ea 0.2 ho 1.0 μm hangata li sebelisoa ho finyella litlhoko tse fapaneng tsa ho sebetsa.
Ts'ebetso ea Phatlalatso: Dispersibility e ntle e thibela ho kopana ha likaroloana, ho netefatsa botsitso ba tharollo ea polishing, le ho ntlafatsa ts'ebetso ea ts'ebetso. Li-powders tse ling tsa boemo bo holimo tsa zirconia, ka mor'a ho fetoloa holimo, li bonts'a thepa e ntle ea ho emisoa ka litharollo tse nang le metsi kapa tse fokolang, tse bolokang ts'ebetso e tsitsitseng nako e fetang lihora tse ngata.
IV. Mekhoa ea Ntlafatso le Pono ea Bokamoso
Ka tsoelo-pele e tsoelang pele ea theknoloji ea nanofabrication,phofo ea zirconiali ntse li ntlafatsoa ho isa bohloeki bo phahameng, kabo e fokolang ea likaroloana, le ho ntlafatsoa ha dispersibility. Lintlha tse latelang li hloka ho eloa hloko nakong e tlang:
1. Tlhahiso ea Boima le Ts'ebeliso ea Litšenyehelo tsa Nano-ScaleLihlahisoa tsa Zirconia
Ho sebetsana le litšenyehelo tse phahameng le mokhoa o rarahaneng oa ho lokisa li-powders tse hloekileng ke senotlolo sa ho khothalletsa tšebeliso ea bona e pharaletseng.
2. Nts'etsopele ea Lisebelisoa tse Kopantsoeng tsa ho Pholisa
Ho kopanya zirconia le lisebelisoa tse kang alumina le silica ho ntlafatsa litekanyetso tsa ho tlosoa le matla a ho laola holim'a metsi.
3. Sisteme ea Mokelikeli o Motala le o Sebelang Tikoloho
Theha mecha ea phatlalatso e se nang chefo, e ka senyehang ea biodegradable le li-additives ho ntlafatsa botsoalle ba tikoloho.
V. Qetello
Zirconium oxide phofo, ka thepa ea eona e babatsehang ea lintho tse bonahalang, e phetha karolo e ntseng e eketseha ea bohlokoa tabeng ea ho bentša ka mokhoa o nepahetseng oa boemo bo holimo. Ka tsoelo-pele e tsoelang pele ea theknoloji ea tlhahiso le tlhokahalo e ntseng e eketseha ea indasteri, ts'ebeliso eazirconium oxide phofoe tla ata haholo, 'me ho lebeletsoe hore e be tšehetso ea mantlha bakeng sa moloko o latelang oa lisebelisoa tsa ho bentša tse sebetsang hantle. Bakeng sa lik'hamphani tse amehang, ho tsamaisana le mekhoa ea ntlafatso ea thepa le ho atolosa lits'ebetso tsa maemo a holimo lefapheng la ho pholisa e tla ba tsela ea bohlokoa ea ho finyella phapang ea lihlahisoa le boeta-pele ba theknoloji.
