Izicelo Eziyinhloko kanye Nenani Lemboni Le-Ultra-Precision/Ultra-Fine Diamond Micropowder
I-micropowder yedayimane enembile kakhulu futhi ecolekile kakhulu, njenge-particle size distribution enzima kakhulu, ebukhali kakhulu, futhi elawuleka kakhulu etholakalayo njengamanje, iba yinto ebalulekile engenakuphikwa ekukhiqizeni ngokunemba. Njengoba izidingo ezikhulayo zekhwalithi ephezulu, ukunemba kokucubungula, kanye nokuthembeka kwezinto ezivela ezimbonini ezifana ne-optics, i-electronics, i-semiconductors, kanye namandla amasha,idayimane elincane eliyimpuphuishintsha kusukela ekugayeni nasekupholisheni kwendabuko kuya ekukhiqizeni okunembe kakhulu, futhi ububanzi bokusetshenziswa kwayo buyaqhubeka nokukhula. Izinhlayiya ze-diamond micropowder ngokuvamile ziphakathi kuka-0.1–10 μm, kanti i-submicron kanye ne-nano-size ultrafine powders ziba yizinto ezisetshenziswayo ekukhiqizeni okuthuthukisiwe. Zinobunzima obuphezulu kakhulu be-Mohs 10, ukuqhuba okuphezulu kokushisa, i-coefficient ephansi yokungqubuzana, kanye namakhono okusika amancane akhiqizwa ngesikhathi sokucubungula, okuvumela ukuqeda kobuso obusezingeni le-athomu ezintweni ezicutshungulwayo. Lokhu kubonakala kakhulu esigabeni sokugcina sokupholisheni samalensi optical, i-sapphire, i-ceramics, amakristalu e-laser, ama-wafer e-semiconductor, kanye nezinsimbi eziqinile kakhulu, lapho zibonisa khona izinzuzo ezingenakuphikwa.
Emikhakheni ye-optics kanye ne-laser,impuphu yedayimane ecwebezelayoIsetshenziswa kakhulu ekupholisheni okunembe kakhulu kwengilazi yokukhanya, amakristalu e-infrared, amafasitela e-sapphire, izibuko ezibonisa ukukhanya okuphezulu, kanye namakristalu e-laser. Imboni ye-optics idinga ubulukhuni obuphezulu kakhulu bomphezulu, ngokuvamile edinga i-Ra < 1 nm. Imiphetho ebukhali yokusika yempuphu yedayimane, esebenza ngendlela ephansi yomonakalo, inciphisa ngempumelelo izendlalelo zokucindezeleka kanye nemifantu emincane, ithuthukise ukuhanjiswa kokukhanya kanye nokusebenza kokukhanya. Ekucubungulweni kwengilazi yeselula ye-sapphire, amafasitela e-infrared, izihlungi zokuxhumana, kanye namalensi e-laser resonator, ama-slurries e-diamond polishing, ama-diamond polishing pads, kanye nama-diamond suspensions kuyizinto ezibalulekile ezisetshenziswayo. Ngaphezu kwalokho, i-ultrafine powder isetshenziswa futhi ezinqubweni ze-MRF (magnetorheological rheological polishing) kanye ne-CMP (chemical mechanical polishing). Ngobuchwepheshe bokulawula usayizi wezinhlayiya kanye nobuchwepheshe bokumboza ubuso, ukusika okufanayo kanye nokupholisheni okunesici esincane kufezwa, okuthuthukisa kakhulu ukusebenza kahle kokucubungula kanye nokukhiqiza izingxenye ze-optical.
Embonini ye-semiconductor kanye ne-electronics, i-powder yedayimane eqondile kakhulu isetshenziswa ekugayeni nasekupholisheni ama-wafer e-silicon, i-silicon carbide (SiC), i-gallium nitride (GaN), ama-substrate e-sapphire, kanye nama-wafer e-compound semiconductor. Ngokukhula okukhulu kwamadivayisi kagesi e-SiC kanye nomkhakha we-semiconductor wesizukulwane sesithathu, ubulukhuni obukhulu kanye nokuphuka kwama-wafer kubeka izidingo eziphezulu ezintweni ezisetshenziswayo zokugaya. I-diamond micropowder ingasusa ngokushesha izinto ngesikhathi sesigaba sokugaya futhi inciphise ubulukhuni bomphezulu ezingeni le-nanometer ngesikhathi sesigaba sokupholisa, inciphise umonakalo womphezulu futhi ngaleyo ndlela ithuthukise ukukhiqizwa kwedivayisi kanye nokusebenza kokushabalalisa ukushisa. Embonini yamaphaneli okubonisa, i-diamond micropowder isetshenziswa kabanzi ekupholisheni okunembile kakhulu kwezimbozo zengilazi, ingilazi yokubuka, ingilazi yekhava ye-3D, kanye nezingxenye ze-AR/VR optical. Ukusebenza kwayo okuphezulu kokucubungula kungafinyeza umjikelezo wokubumba, kuthuthukise ukuhambisana komkhiqizo, futhi kuthuthukise kakhulu ukukhiqizwa komugqa wokukhiqiza kanye nesikhathi somjikelezo.
Emasimini anokuqina okuphezulu njenge-carbide eqinisiwe, izinto zobumba, kanye nezinto ezihlanganisiwe ze-metal matrix, i-micropowder yedayimane e-ultrafine isetshenziswa kabanzi ekugayeni ngokunembile imiphetho yamathuluzi, ukupholisha ngokunembile isikhunta, ukuqinisa ubuso bezingxenye zesakhiwo sezindiza, kanye nokwakha ngokunembile. Ngenkathi amathuluzi e-carbide aqinisiwe angathuthukisa ukumelana nokuguguleka kanye nokusika impilo ngemva kokudlula kanye nokupholisha imiphetho,idayimane elincane eliyimpuphu ingafinyelela ukusika okuncane ngenkathi igcina ubukhali, okuholela esakhiweni esincane esifanayo nesiyindilinga onqenqemeni oluphambili. Embonini yokubumba ngokunemba, njengemibhobho yokujova, isikhunta esikhipha insimbi, kanye nesikhunta esibonakalayo, ukupholisha i-diamond micron powder kungafinyelela imiphumela efana nesibuko esingaphansi kwe-nanometer, kuthuthukise kakhulu impilo yesikhunta, ukusebenza okuncishisiwe, kanye nekhwalithi yokubumba. Ezimbonini zezimoto, zezindiza, kanye nemishini yamandla, i-diamond micron powder nayo isetshenziselwa ukugaya ngokunemba okukhulu kwezinye izinto ezikhethekile, njengezingxenye ze-turbine eqinile ye-ceramic, ama-superalloy asekelwe ku-nickel, kanye nama-composites e-carbon fiber, okunikeza izingxenye ukuthembeka okuphezulu kanye nokuqina kokusebenza.
Njengoba amasimu okufaka isicelo eqhubeka nokukhula, ubuchwepheshe bokulungiselela i-powder ye-micron yedayimane enembile kakhulu buthuthukiswa njalo. Njengamanje, izindlela zokulungiselela ezijwayelekile zifaka phakathi ukuchoboza idayimane yokwenziwa enamandla aphezulu, ukuqhuma (i-nanodiamond), izindlela zamakhemikhali, kanye namasu okuguqula ubuso. Ukuze kuhlangatshezwane nezidingo eziphakeme zokuzinza nokumiswa embonini ye-optics kanye ne-semiconductor, i-powder ye-micron esezingeni eliphezulu ivame ukumbozwa, njengezinsimbi, izinto ezingaphili, izinto eziphilayo, kanye nama-surfactants, ngaleyo ndlela kuthuthukiswe ukuhlakazeka, ukumelana nokushisa, kanye nokuvumelana kokucubungula. Idayimane enezinhlamvu ezicwebezelayo kancane kancane ithatha indawo yendabuko.izinto zokupholishanjenge-cerium oxide kanyei-aluminaezinqubweni ze-CMP, okuthuthukisa kakhulu ukuthamba nokusebenza kahle kokucubungula kwama-wafers nezingxenye ze-optical. Esikhathini esizayo, ngokuthuthukiswa kokukhiqiza okuhlakaniphile, ukuxhumana kwe-quantum, amadivayisi ezokwelapha anembile kanye namadivayisi e-optoelectronic athuthukile, i-ultra-precision diamond micro powder izoqhubeka nokwandisa imingcele yayo yokusetshenziswa futhi ibe yinto ebalulekile eyisisekelo embonini yokucubungula izinto.
