Mashandisirwo Akakosha uye Kukosha Kweindasitiri kweUpfu hweDaimondi Hwakanyatsogadzirwa/Hwakanaka Zvakanyanya
Upfu hwedhaimani hwakanyatsonaka uye hwakatsetseka, sehupfu hwakaoma kwazvo, hwakapinza, uye hunogona kudzorwa hunowanikwa parizvino, huri kuva chinhu chakakosha chisingatsivike mukugadzira zvinhu nemazvo. Nekuwedzera kwekuda kwemhando yepamusoro, kunyatsogadzirisa zvinhu, uye kuvimbika kwezvinhu kubva kumaindasitiri akadai se optics, electronics, semiconductors, uye simba idzva,upfu hwedhaimaniiri kuchinja kubva pakukuya nekupukuta kwechinyakare kuenda pakugadzira zvinhu zvine hungwaru hwepamusoro-soro, uye huwandu hwekushandiswa kwayo huri kuramba huchiwedzera. Zvidimbu zvemadhaimani zveupfu hwemicrofiber zvinowanzova pakati pe0.1–10 μm, neupfu hwesubmicron nehukuru hwenano-sized ultrafine huchive zvinhu zvekushandisa mukugadzira kwepamusoro-soro. Dzine hunyoro hwakanyanya hweMohs 10, high thermal conductivity, low coefficient of friction, uye micro-cutting capabilities dzinogadzirwa panguva yekugadzirisa, zvichiita kuti atomic-level surface finishes ishande pazvinhu zvakagadzirwa. Izvi zvinonyanya kuoneka muchikamu chekupedzisira chekupukuta kwema optical lenses, sapphire, ceramics, laser crystals, semiconductor wafers, uye ultrahard metals, uko zvinoratidza mabhenefiti asingatsiviwi.
Muminda ye optics ne lasers,upfu hwedhaimani hwakatsetsekainonyanya kushandiswa pakupukuta girazi re optical, makristaro e infrared, mahwindo e sapphire, magirazi e high-reflectivity, uye makristaro e laser. Indasitiri ye optics inoda kukwirira kwakanyanya pamusoro, kazhinji inoda Ra < 1 nm. Micheto yakapinza ye diamond powder, inoshanda nenzira isina kukuvara zvakanyanya, inoderedza zvinobudirira stress layers uye microcracks, ichivandudza light transmittance uye optical performance. Mukugadzirisa magirazi efoni e sapphire, mahwindo e infrared, ma telecommunication filters, uye laser resonator lenses, diamond polishing slurries, diamond polishing pads, uye diamond suspensions zvinhu zvakakosha zvinoshandiswa. Uyezve, ultrafine powder inoshandiswawo mu MRF (magnetorheological rheological polishing) uye CMP (chemical mechanical polishing). Kuburikidza nehunyanzvi hwekutonga saizi ye particle uye surface coating, kucheka kwakafanana uye low-defect polishing zvinowanikwa, zvichivandudza zvakanyanya kushanda kwe processing uye goho re optical components.
Muindasitiri ye semiconductor neyemagetsi, upfu hwedhaimani hwakanyanya kunaka hunoshandiswa pakukuya nekupukuta mawafer esilicon, silicon carbide (SiC), gallium nitride (GaN), sapphire substrates, uye mawafer e semiconductor akasanganiswa. Nekukura kwakanyanya kwemidziyo yeSiC uye indasitiri ye semiconductor yechizvarwa chechitatu, kuomarara kwakanyanya uye kuputsika kwemawafer kunoisa kudiwa kwakanyanya pakushandisa zvinodyiwa pakukuya. Upfu hwedhaimani hunogona kubvisa zvinhu nekukurumidza panguva yekukuya uye kuderedza kuomarara kwenzvimbo kusvika padanho re nanometer panguva yekupukuta, zvichideredza kukuvara kwenzvimbo uye nokudaro zvichivandudza kugona kwemidziyo uye kupisa. Muindasitiri ye display panel, upfu hwedhaimani hunoshandiswa zvakanyanya pakupukuta magirazi, magirazi ewachi, magirazi e3D cover, uye AR/VR optical components. Kushanda kwayo kwepamusoro kwekugadzirisa kunogona kupfupisa kutenderera kwekuumba, kuvandudza kugara kwechigadzirwa, uye kuvandudza zvakanyanya kugona kwemutsetse wekugadzira nenguva yekutenderera.
Munzvimbo dzine kuomarara kwakawanda dzakadai se cemented carbide, ceramics, uye metal matrix composites, ultrafine diamond micropowder inoshandiswa zvakanyanya pakukuya mipendero yemidziyo nemazvo, kupukuta maforoma nemazvo, kusimbisa pamusoro pezvikamu zvemuchadenga, uye kugadzira nemazvo. Kunyange hazvo zvishandiso zve cemented carbide zvichigona kuvandudza kuramba kupfeka uye kucheka hupenyu mushure mekupwanya uye kupukuta,upfu hwedhaimani inogona kuita kuti icheke zvishoma uku ichiramba yakapinza, zvichikonzera kuti pave nechimiro chakafanana uye chakatenderera pamucheto wepamusoro. Muindasitiri yemhando yemhando yemhando yemhando ye "molds" chaiyo, senge ma "injection molds", ma "die-casting molds", uye ma "optical molds", "diamond micron powder polishing" inogona kuita kuti pave nemhedzisiro yakafanana negirazi, ichivandudza zvakanyanya hupenyu hwemhando ye "mold", "demolding performance", uye mhando ye "molding". Muindasitiri yemotokari, yendege, uye yemagetsi, "diamond micron powder" inoshandiswawo pakukuya zvinhu zvakakosha, zvakaita se "hard ceramic turbine components", "nickel-based superalloys", uye "carbon fiber composites", zvichipa zvikamu kuvimbika kwakanyanya uye kugadzikana kwekushanda.
Sezvo minda yekushandisa ichiramba ichikura, tekinoroji yekugadzira upfu hwemadhiyamondi micron hwakanyatsogadzirwa iri kuramba ichivandudzwa. Parizvino, nzira dzekugadzira dzakakurumbira dzinosanganisira kupwanya madhiyamondi akagadzirwa zvine simba guru, kupwanya (nanodiamond), nzira dzemakemikari, uye matekiniki ekugadzirisa pamusoro. Kuti zvizadzise zvinodiwa zvepamusoro zvekugadzikana uye kumisa muindasitiri ye optics ne semiconductor, upfu hwemadhiyamondi hwemhando yepamusoro hunowanzo putirwa, senge nesimbi, inorganics, organics, uye surfactants, nokudaro zvichivandudza kupararira, kuramba kupisa, uye kugadzikana kwekugadzirisa. Dhayamondi yakagadzirwa ne ultrafine iri kutsiva zvishoma nezvishoma tsika dzechinyakare.zvinhu zvekupukutazvakaita se cerium oxide uyealuminamumaitiro eCMP, zvichiwedzera kuvandudza kutsetseka uye kushanda zvakanaka kwemawafers nezvikamu zve optical. Mune ramangwana, nekuvandudzwa kwekugadzirwa kwakangwara, kutaurirana kwequantum, zvishandiso zvekurapa zvakanyatsonaka uye zvishandiso zve optoelectronic zvepamusoro, upfu hwemadhaimani hwakanyatsonaka hucharamba huchiwedzera miganhu yekushandisa uye huchava chinhu chakakosha muindasitiri yekugadzirisa zvinhu.
