Nhanganyaya kune zvitema silicon zvigadzirwa uye kushandisa kwavo mujecha
Black siliconchinhu chinoshanda chesilicon chine chimiro chepamusoro chepamusoro, chakatumidzwa simba rayo rekunyudza mwenje uye yakasarudzika micro-nano pamusoro morphology. Mumakore achangopfuura, nekuvandudzwa kwehutano hwepamusoro uye zvinodiwa zvekushanda kwezvinhu mukugadzirwa kwepamusoro-soro, silicon nhema yakashandiswa zvakanyanya mu photovoltaics, optoelectronics, semiconductors, optical component kugadzira uye mamwe minda ine yakanakisa yemuviri uye makemikari zvinhu. Panguva imwecheteyo, silicon nhema yakapinda zvishoma nezvishoma muindasitiri yejecha uye yave rudzi rutsva rwezvinhu zvejecha zvine mashandiro akanaka.
Ⅰ. Basic maitiro e black silicon
Siricon yakasviba inoumbwa nekurapa iyo silicon pamusoro kuburikidza neakatevedzana e-micro-nano chimiro chekugadzirira matekinoroji (senge reactive ion etching, metal-assisted chemical etching, laser-induced etching, etc.). Kumusoro kwayo kunopa dense cone kana columnar chimiro, chinogona kuderedza zvakanyanya kutaridzika kwechiedza. Iyo reflectivity mune inooneka kune iri pedyo-infrared bhendi inogona kunyange kuva isingasviki 1%, saka yakasviba yakasviba pakuonekwa.
Black silicon haingove neakanakisa optical zvimiro, asi zvakare ine zvakanakira kuomarara kwepamusoro, kuchena kwepamusoro, kusamira kwekupfeka, uye kusagadzikana kwekuora. Chimiro chayo chechidimbu chakasimba uye chakakodzera kutenderera kwakawanda pasi peyakanyanya-kumhanya kwemamiriro ezvinhu. Inoita zvirinani mukuputira jecha pane zvechinyakare abrasives senge white corundum, brown corundum, quartz jecha, nezvimwe.
Ⅱ. Zvakanakira nhema silicon mune sandblasting
Sandblasting inzira yekurapa pamusoro iyo inoshandisa yakakwira-kumhanya jecha kuyerera kukanganisa pamusoro kuti iwane kuchenesa, kubviswa kweiyo oxide layer, roughening kana yekushongedza mhedzisiro. Seyepamusoro-inoita abrasive, nhema silicon ine mabhenefiti ari pachena mumunda wejecha:
1. Yakanaka uye yakafanana pamusoro pekuita
Iyo geometric chimiro cheblack silicon particles ndeyenguva dzose uye morphology yakagadzikana. Mushure mekupfapfaidza, inogona kuumba yunifomu uye inowirirana matte maitiro pamusoro peiyo workpiece. Iyi mhedzisiro yekurapa inonyanya kukodzera zvigadzirwa zvakaita segirazi remaziso, lens housing, aluminium alloy structural parts, nezvimwewo zvine zvakanyanyisa zvinodikanwa zvekuenderana uye kutaridzika.
2. High kuoma uye kukanganisa kuramba
Iyo Mohs kuomarara kwesilicon nhema yakakwira kusvika 8.5 kana pamusoro, mwero wekuputsika panguva yejecha yakaderera, uye hupenyu hwesevhisi hurefu. Kuenzaniswa nejecha requartz rakajairwa kana magirazi mabhero, nhema silicon sandblasting inoshanda zvakanyanya uye ine simba rakasimba rekuita, uye inogona kupedzisa kuchenesa kwakadzama uye roughen munguva pfupi.
3. Kuchena kwepamusoro uye kuchengetedzwa kwezvakatipoteredza
Kuchena kwesilicon nhema kazhinji kunopfuura 99%, uye haina tsvina inokuvadza senge silicon yemahara kana simbi inorema. Iyo ine yakaderera kusvibiswa kweguruva mumusangano wejecha uye inonyanya kukodzera kushandiswa mumaindasitiri ehutsanana akadai sezvikamu zvemagetsi, zvishandiso zvekurapa, uye semiconductor packaging. Panguva imwecheteyo, chimiro chayo chechidimbu chakagadzikana, kugadzirwa kweguruva idiki, uye yakachengeteka kune hutano hwevashandisi.
4. Inoshandiswa zvakare uye inodhura-inodzorwa
Nekuda kwekuoma kwayo kwakanyanya uye kugadzikana kwechimiro, dema silicon inogona kuramba ichichengetedza yakanaka yekupfapfaidza mhedzisiro mushure mekutenderera kwakawanda, ichideredza zvakanyanya kurasikirwa kwezvinhu. Mune yakakura-yakakura otomatiki sandblasting michina, nhema silicon inoratidza hupfumi huri nani.
Ⅲ. Nzvimbo dzekushandisa dzakajairika
Black silicon sandblasting abrasives yakashandiswa zvakanyanya mundima dzinotevera:
Precision hardware surface matte treatment: yakadai sepamusoro-soro mbozhanhare yepakati furemu, ganda rekunyorera, smart watch shell uye zvimwe zvigadzirwa zvealuminium alloy;
Optical glass frosting treatment: inoshandiswa kune lens, filter, optical window matte uye kushongedza;
Aerospace uye zvikamu zvemauto: bvisa iyo oxide layer pasina kushandura saizi kuti uvandudze iyo yekunamatira adhesion;
Electronic package pamusoro etching: kunatsiridza kurongedza kurongeka uye interface adhesion;
Ceramic uye composite zvinhu micro-sandblasting: pamusoro roughening kurapwa kuwedzera bonding simba.
Ⅳ. Summary
Nekuenderera mberi kwekuvandudza tekinoroji yejecha uye indasitiri yekugadzira ichienda yakanangana nepamusoro-soro uye nepamusoro pekuchengetedzwa kwezvakatipoteredza, zvechinyakare sandblasting zvinhu hazvichakwanisa kuzadzisa zvinodiwa zve-high-end process. Sirikoni yakasviba, sechinhu chinoshanda chine simba rakawanda, kuratidzira kwakadzika, kuchena kwepamusoro uye kuchengetedza kwezvakatipoteredza, iri kuve chinhu chakakosha chekusimudzira muindasitiri yejecha. Ingave mukugadzirwa kwayo chaiko, matte yemaziso, kana mukugadzirwa kwemagetsi mudziyo, midziyo yemuchadenga yekumisikidza uye mimwe minda, silicon nhema yakaratidza tarisiro yakakura yekushandisa.
