Izicelo eziphambili kunye nexabiso leShishini le-Ultra-Precision/Ultra-Fine Diamond Micropowder
Umgubo wedayimani ochanekileyo kakhulu nocolekileyo kakhulu, njengowona unzima, ubukhali, kwaye ulawuleka kakhulu wokusasazwa kobukhulu bamasuntswana onzima kakhulu okhoyo ngoku, uba yinto ebalulekileyo engenakutshintshwa kwimveliso echanekileyo. Ngenxa yokwanda kweemfuno zomgangatho womphezulu, ukuchaneka kokucubungula, kunye nokuthembeka kwezinto ezivela kumashishini afana ne-optics, i-electronics, ii-semiconductors, kunye namandla amatsha,umgubo wedayimani omncinciisuka ekugayeni nasekupolisheni kwendabuko ukuya ekuveliseni okuchanekileyo kakhulu, kwaye ububanzi bokusetyenziswa kwayo buyanda rhoqo. Iisuntswana zedayimani micropowder ngokubanzi ziphakathi kwe-0.1–10 μm, kunye ne-submicron kunye ne-nano-sized ultrafine powders eziba zizinto ezisetyenziswa kakhulu kwimveliso ephucukileyo. Zinobunzima obuphezulu kakhulu be-Mohs 10, ukuqhuba okuphezulu kobushushu, i-coefficient ephantsi yokungqubana, kunye nokukwazi ukusika okuncinci okwenziwa ngexesha lokucubungula, okuvumela ukugqitywa komphezulu we-atom kwizixhobo ezicutshungulwayo. Oku kubonakala ngakumbi kwinqanaba lokugqibela lokupolisha leelensi ze-optical, i-sapphire, i-ceramics, iikristale ze-laser, ii-wafers ze-semiconductor, kunye neentsimbi ezinzima kakhulu, apho zibonisa khona iingenelo ezingenakutshintshwa.
Kwimiba ye-optics kunye ne-laser,umgubo wedayimani ocoliweyo kakhuluIsetyenziswa kakhulu ekupolisheni ngokuchanekileyo kweglasi ye-optical, iikristale ze-infrared, iifestile ze-sapphire, izibuko ezibonisa ukukhanya okuphezulu, kunye neekristale ze-laser. Ishishini le-optics lifuna uburhabaxa obuphezulu kakhulu bomphezulu, obudla ngokufuna i-Ra < 1 nm. Imiphetho ebukhali yokusika yedayimani, esebenza kwimo yomonakalo omncinci, inciphisa ngempumelelo iileya zoxinzelelo kunye nee-microcracks, iphucula ukuhanjiswa kokukhanya kunye nokusebenza kwe-optical. Ekucutshungulweni kweglasi yefowuni ye-sapphire, iifestile ze-infrared, izihluzi zonxibelelwano, kunye neelensi ze-laser resonator, ii-slurries ze-diamond polishing, ii-diamond polishing pads, kunye ne-diamond suspensions zizinto ezibalulekileyo ezisetyenziswayo. Ngaphezu koko, i-ultrafine powder ikwasetyenziswa kwiinkqubo ze-MRF (magnetorheological rheological polishing) kunye ne-CMP (chemical mechanical polishing). Ngolawulo oluchanekileyo lobungakanani be-particle kunye netekhnoloji yokugquma umphezulu, ukusika okufanayo kunye ne-low-defect polishing ziyafezekiswa, okuphucula kakhulu ukusebenza kakuhle kokucubungula kunye nemveliso yezixhobo ze-optical.
Kwishishini le-semiconductor kunye ne-elektroniki, umgubo wedayimani ochanekileyo kakhulu usetyenziswa ekugayweni nasekupolishweni kwee-wafers ze-silicon, i-silicon carbide (SiC), i-gallium nitride (GaN), ii-substrates ze-sapphire, kunye nee-wafers ze-semiconductor ezihlanganisiweyo. Ngokukhula okukhulu kwezixhobo zamandla ze-SiC kunye neshishini le-semiconductor lesizukulwana sesithathu, ubulukhuni obuphezulu kunye nokuqhekeka kwee-wafers kubeka iimfuno eziphezulu kwizinto ezisetyenziswayo zokugaywa. I-Diamond micropowder inokususa ngokukhawuleza izinto ngexesha lesigaba sokugaywa kwaye inciphise uburhabaxa bomphezulu ukuya kwinqanaba le-nanometer ngexesha lesigaba sokugaywa, inciphise umonakalo womphezulu kwaye ngaloo ndlela iphucule isivuno sesixhobo kunye nokusebenza kokusasazwa kobushushu. Kwishishini lephaneli yokubonisa, i-diamond micropowder isetyenziswa kakhulu ekupolishweni ngokuchanekileyo kakhulu kwezigqubuthelo zeglasi, iglasi yewotshi, iglasi yokugubungela ye-3D, kunye nezixhobo ze-AR/VR optical. Ukusebenza kwayo okuphezulu kokucubungula kunokunciphisa umjikelo wokubumba, kuphucule ukuhambelana kwemveliso, kwaye kuphucule kakhulu isivuno somgca wemveliso kunye nexesha lomjikelo.
Kwimimandla yokuqina okuphezulu njenge-carbide eqinisiweyo, iiseramikhi, kunye nee-metal matrix composites, i-ultrafine diamond micropowder isetyenziswa kakhulu ekugayeni ngokuchanekileyo imiphetho yezixhobo, ukupolisha ngokuchanekileyo iimolds, ukuqinisa umphezulu wezinto zokwakha ze-aerospace, kunye nokwenza ngokuchanekileyo. Ngelixa izixhobo ze-carbide eziqinisiweyo zinokuphucula ukumelana nokuguguleka kunye nokunciphisa ubomi emva kokudlula kunye nokupolisha,umgubo wedayimani omncinci inokufikelela ekusikeni okuncinci ngelixa igcina ubukhali, nto leyo ekhokelela kwisakhiwo esilinganayo nesijikelezileyo kumda ophambili. Kwishishini lokubumba okuchanekileyo, njengee-injection molds, ii-die-casting molds, kunye nee-optical molds, i-diamond micron powder polishing inokufikelela kwiziphumo ezifana nesipili esingaphantsi kwe-nanometer, iphucula kakhulu ubomi bokubumba, ukusebenza okuncitshisiweyo, kunye nomgangatho wokubumba. Kwimizi-mveliso yeemoto, yeenqwelo-moya, kunye nezixhobo zamandla, i-diamond micron powder ikwasetyenziselwa ukugaywa ngokuchanekileyo kwezinye izinto ezikhethekileyo, ezinje ngezinto ze-turbine ze-ceramic ezinzima, ii-superalloys ezisekwe kwi-nickel, kunye nee-carbon fiber composites, nto leyo enika iindawo ukuthembeka okuphezulu kunye nokuzinza kokusebenza.
Njengoko amasimi okufaka isicelo eqhubeka esanda, itekhnoloji yokulungiselela ipowder ye-micron yedayimani echanekileyo kakhulu nayo ihlaziywa rhoqo. Okwangoku, iindlela zokulungiselela eziphambili ziquka ukutyumza idayimani yokwenziwa enamandla aphezulu, ukuqhushumba (i-nanodiamond), iindlela zeekhemikhali, kunye neendlela zokuguqula umphezulu. Ukuhlangabezana neemfuno eziphezulu zozinzo kunye nokumiswa kwimizi-mveliso ye-optics kunye ne-semiconductor, ipowder ye-micron esemgangathweni idla ngokugqunywa, njengeentsimbi, izinto ezingaphiliyo, izinto eziphilayo, kunye ne-surfactants, ngaloo ndlela kuphucula ukusasazeka, ukumelana nobushushu, kunye nokuhambelana kokucubungula. Idayimani ehluzwe nge-ultrafine ithatha indawo yendabuko kancinci kancinci.izinto zokupolishaezifana ne-cerium oxide kunyei-aluminakwiinkqubo ze-CMP, nto leyo ephucula ngakumbi ukuthamba nokusebenza kakuhle kwee-wafers kunye nezixhobo ze-optical. Kwixesha elizayo, ngophuhliso lwemveliso ekrelekrele, unxibelelwano lwe-quantum, izixhobo zonyango ezichanekileyo kunye nezixhobo ze-optoelectronic eziphambili, i-ultra-precision diamond micro powder iya kuqhubeka nokwandisa imida yayo yokusetyenziswa kwaye ibe yinto ebalulekileyo ebalulekileyo kwishishini lokucubungula izixhobo.
