Nhanganyaya yezvigadzirwa zve silicon nhema uye kushandiswa kwazvo mukuputika kwejecha
Silikoni nhemachinhu chinoshanda chesilicon chine chimiro chakakosha pamusoro, chakapihwa zita nekuda kwekugona kwaro kupinza chiedza kwakasimba uye chimiro chayo che micro-nano surface. Mumakore achangopfuura, nekuvandudzwa kwekunyatso gadzirisa pamusoro uye zvinodiwa pakushanda kwezvinhu mukugadzira kwepamusoro-soro, black silicon yave ichishandiswa zvakanyanya mu photovoltaics, optoelectronics, semiconductors, optical component manufacturing nedzimwe nzvimbo dzine hunhu hwayo hwakanaka hwepanyama nemakemikari. Panguva imwe chete, black silicon yakapinda zvishoma nezvishoma muindasitiri ye sandblasting pamusoro uye yave rudzi rutsva rwe sandblasting ine mashandiro akanaka kwazvo.
Ⅰ. Hunhu hwepakutanga hwesilicon nhema
Silikoni nhema inoumbwa nekurapa pamusoro pesilicon kuburikidza netekinoroji dzakasiyana-siyana dzekugadzira chimiro che micro-nano (senge reactive ion etching, metal-assisted chemical etching, laser-induced etching, nezvimwewo). Pamusoro payo pane dense cone kana columnar structure, izvo zvinogona kuderedza zvakanyanya reflectivity yechiedza. Reflectivity iri mu vision to near-infrared band inogona kutove pasi pe1%, saka ine chitarisiko cherima dema.
Silikoni nhema haina chete hunhu hwakanaka hwekuona, asiwo ine zvakanakira kuomarara kwakanyanya, kuchena kwakanyanya, kuramba kupfeka, uye kuramba ngura. Maumbirwo ayo ezvikamu akasimba uye akakodzera kutenderera kakawanda mumamiriro ezvinhu ekumhanya kukuru. Inoshanda zviri nani mukuputika kwejecha pane zvinokuvadza zvechinyakare zvakaita sewhite corundum, brown corundum, quartz jecha, nezvimwewo.
Ⅱ. Mabhenefiti esilicon nhema mukuputika kwejecha
Kuputira jecha inzira yekurapa pamusoro inoshandisa jecha rinoyerera nekukurumidza kuti riparadze pamusoro kuti richenese, ribvise oxide layer, riite roughening kana kuti rishongedze. Senzira yekubvisa jecha inoshanda zvakanyanya, black silicon ine zvakanakira zviri pachena mumunda wekuputika jecha:
1. Mhedzisiro yakanaka uye yakafanana pamusoro
Maumbirwo esimbi dzesilicon nhema akafanana uye chimiro chayo chakasimba. Mushure mekupfapfaidza, inogona kugadzira chinhu chakafanana uye chakafanana pamusoro pechinhu chebasa. Izvi zvinonyanya kukodzera zvigadzirwa zvakaita segirazi re optical, lens housing, aluminium alloy structure parts, nezvimwewo zvine zvinodiwa zvakanyanya kuti chitarisiko uye chionekwe zvakanaka.
2. Kuomarara kwakanyanya uye kuramba kukanganiswa
Kuomarara kwesimbi yesilicon nhema yeMohs kwakakwira kusvika 8.5 kana kupfuura, mwero wekutyoka panguva yekuputira jecha wakaderera, uye hupenyu hwebasa hwakareba. Kana tichienzanisa nejecha requartz kana magirazi, kuputira jecha nhema yesilicon inoshanda zvakanyanya uye ine simba rakasimba rekurova, uye inogona kupedzisa kuchenesa kwakadzama uye kupwanya munguva pfupi.
3. Kuchena kwakanyanya uye kuchengetedzwa kwezvakatipoteredza
Kuchena kwesilicon nhema kunowanzova pamusoro pe99%, uye haina tsvina inokuvadza senge silicon yakasununguka kana simbi dzinorema. Ine guruva shoma munzvimbo yekugadzira sandblasting uye yakakodzera kushandiswa mumaindasitiri ane hutsanana hwakanyanya senge zvikamu zvemagetsi, zvishandiso zvekurapa, uye mapurasitiki e semiconductor. Panguva imwe chete, chimiro chayo chezvidimbu chakagadzikana, kugadzirwa kweguruva kudiki, uye yakachengeteka kune hutano hwevashandi.
4. Inogona kushandiswazve uye inodzorwa nemutengo
Nekuda kwekuoma kwayo kwakanyanya uye kugadzikana kwechimiro, silicon nhema inogona kuramba ichipfapfaidza zvakanaka mushure menguva dzakawanda, zvichideredza zvakanyanya kurasikirwa kwezvinhu. Mumichina mikuru yekuputika jecha otomatiki, silicon nhema inoratidza hupfumi huri nani.
Ⅲ. Nzvimbo dzakajairika dzekushandisa
Mabrasive eblack silicon sandblasting anoshandiswa zvakanyanya muminda inotevera:
Kurapa kwakanyatsogadzirwa kwehardware pamusoro pematte: senge furemu yepakati yefoni yepamusoro, shell yenotebook, shell yewachi yakangwara nezvimwe zvigadzirwa zvealuminium alloy;
Kurapa kwegirazi regirazi rekuona: rinoshandiswa kune lenzi, firita, mahwindo ekuona uye kushongedza;
Zvikamu zvemuchadenga nemauto: bvisai oxide layer pasina kuchinja saizi kuti muvandudze coating adhesion;
Kucheka pamusoro pemapakeji emagetsi: kunatsiridza kurongeka kwepakeji uye kunamira kweinterface;
Kuputira jecha diki nesimbi yeceramic: kugadzirisa kusimba kwekubatana kwesimbi nesimbi.
Ⅳ. Pfupiso
Nekuvandudzwa kuri kuramba kuchiitwa tekinoroji yekuputika kwejecha uye indasitiri yekugadzira zvinhu iri kufambira mberi pakunyatsorurama uye kuchengetedzwa kwakanyanya kwezvakatipoteredza, zvinhu zvechinyakare zvekuputika kwejecha hazvichakwanisi kusangana nezvinodiwa nemaitiro epamusoro-soro. Silikoni nhema, senzira inoshanda yekukwesha ine simba rakawanda, kuratidzira kwakaderera, kuchena kwakanyanya uye kuchengetedzwa kwezvakatipoteredza, iri kuva chinhu chakakosha chekuvandudza muindasitiri yekuputika kwejecha. Ingave mukugadzira kwakanyatsojeka, optical matte, kana mukugadzirisa zvishandiso zvemagetsi, kugadzirira kwepamberi kwemidziyo yemuchadenga nedzimwe nzvimbo, silicon nhema yakaratidza mikana yakawanda yekushandisa.
