Hoʻolauna i nā huahana silicon ʻeleʻele a me kā lākou noi i ka oneblasting
Silika ʻeleʻeleHe mea silicon hana me kahi ʻano ʻili kūikawā, i kapa ʻia no kona hiki ke komo māmā ikaika loa a me ke ʻano ʻili micro-nano kū hoʻokahi. I nā makahiki i hala iho nei, me ka hoʻomaikaʻi ʻana i ka pololei o ka mālama ʻana i ka ʻili a me nā koi hana mea i ka hana kiʻekiʻe, ua hoʻohana nui ʻia ka silicon ʻeleʻele i nā photovoltaics, optoelectronics, semiconductors, hana ʻāpana optical a me nā kahua ʻē aʻe me kona mau waiwai kino a me ke kemika maikaʻi loa. I ka manawa like, ua komo mālie ka silicon ʻeleʻele i ka ʻoihana oneblasting ʻili a ua lilo i ʻano mea oneblasting hou me ka hana maikaʻi loa.
Ⅰ. Nā ʻano kumu o ka silicon ʻeleʻele
Hoʻokumu ʻia ka silicon ʻeleʻele ma ka mālama ʻana i ka ʻili silicon ma o kahi moʻo o nā ʻenehana hoʻomākaukau ʻano micro-nano (e like me ke reactive ion etching, metal-assisted chemical etching, laser-induced etching, a pēlā aku). Hōʻike kona ʻili i kahi cone dense a i ʻole columnar structure, hiki ke hōʻemi nui i ka reflectivity o ka mālamalama. ʻO ka reflectivity i loko o ka ʻike ʻia e ka band kokoke-infrared hiki ke emi ma mua o 1%, no laila he ʻeleʻele ʻeleʻele ke ʻano.
ʻAʻole wale nā waiwai optical maikaʻi loa o ka silicon ʻeleʻele, akā loaʻa pū kekahi mau pono o ka paʻakikī kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa ʻana i ka pala. He ikaika kona ʻano ʻāpana a kūpono no nā pōʻaiapuni he nui ma lalo o nā kūlana hopena wikiwiki. Hana maikaʻi ia i ka oneblasting ma mua o nā abrasives kuʻuna e like me ke corundum keʻokeʻo, ka corundum ʻeleʻele, ke one quartz, a pēlā aku.
Ⅱ. Nā pono o ka silicon ʻeleʻele i ka oneblasting
ʻO ke one ʻana he ʻano hana mālama ʻili e hoʻohana ana i ke kahe one wikiwiki e hoʻopilikia i ka ʻili e hoʻokō ai i ka hoʻomaʻemaʻe, wehe ʻana i ka papa oxide, roughening a i ʻole nā hopena hoʻonaninani. Ma ke ʻano he abrasive hana kiʻekiʻe, loaʻa i ka silicon ʻeleʻele nā maikaʻi maopopo ma ke kahua o ke one ʻana:
1. Ka hopena ʻili maikaʻi a like
He kūlike ke ʻano geometric o nā ʻāpana silicon ʻeleʻele a paʻa ke ʻano. Ma hope o ka pīpī ʻana, hiki iā ia ke hana i kahi hopena matte like a kūlike ma luna o ka ʻili o ka mea hana. He kūpono loa kēia hopena lapaʻau no nā huahana e like me ke aniani optical, ka hale lens, nā ʻāpana kūkulu alumini alloy, a me nā mea ʻē aʻe i loaʻa nā koi kiʻekiʻe loa no ke kūlike o ka ʻili a me ke ʻano.
2. Paʻakikī kiʻekiʻe a me ke kūpaʻa hopena
ʻOi aku ka paʻakikī o ka silicon ʻeleʻele ma mua o 8.5, haʻahaʻa ka nui o ka haki ʻana i ka wā o ka one ʻana, a lōʻihi ke ola lawelawe. Ke hoʻohālikelike ʻia me ke one quartz maʻamau a i ʻole nā mīkini aniani, ʻoi aku ka maikaʻi o ka one silicon ʻeleʻele a he ikaika ka hopena, a hiki ke hoʻopau i ka hoʻomaʻemaʻe hohonu a me ka roughing i ka manawa pōkole.
3. Maʻemaʻe kiʻekiʻe a me ka palekana o ke kaiapuni
ʻOi aku ka maʻemaʻe o ka silicon ʻeleʻele ma mua o 99%, a ʻaʻohe ona haumia ʻino e like me ka silicon manuahi a i ʻole nā metala kaumaha. He haʻahaʻa ka haumia lepo i loko o ka hale hana one-blasting a kūpono loa ia no ka hoʻohana ʻana i nā ʻoihana maʻemaʻe kiʻekiʻe e like me nā ʻāpana uila, nā mea lapaʻau, a me nā ʻōpala semiconductor. I ka manawa like, paʻa kona ʻano ʻāpana, liʻiliʻi ka hana ʻana o ka lepo, a ʻoi aku ka palekana no ke olakino o nā mea hana.
4. Hiki ke hoʻohana hou ʻia a hiki ke kāohi ʻia ke kumukūʻai
Ma muli o kona paʻakikī kiʻekiʻe a me ke kūpaʻa o ke kūkulu ʻana, hiki i ka silicon ʻeleʻele ke mālama i kahi hopena pīpī maikaʻi ma hope o nā pōʻaiapuni he nui, e hōʻemi nui ana i ka nalowale o nā mea. I nā lako hana one one nui, hōʻike ka silicon ʻeleʻele i ka hoʻokele waiwai maikaʻi.
I. Nā wahi noi maʻamau
Ua hoʻohana nui ʻia nā mea hoʻoheheʻe sandblasting silicon ʻeleʻele ma nā kahua aʻe:
Ka mālama ʻana i ka ʻilikai matte kikoʻī: e like me ke kikowaena waena kelepona paʻalima kiʻekiʻe, ka pūpū puke noke, ka pūpū uaki akamai a me nā huahana aluminika ʻē aʻe;
ʻO ka mālama ʻana i ka aniani ʻōlinolino: hoʻohana ʻia no ka lens, kānana, optical window matte a me ka mea hoʻonaninani;
ʻO nā ʻāpana Aerospace a me nā pūʻali koa: wehe i ka papa oxide me ka ʻole o ka hoʻololi ʻana i ka nui e hoʻomaikaʻi i ka hoʻopili ʻana o ka uhi;
ʻO ke kālai ʻana i ka ʻili o ka pūʻolo uila: hoʻomaikaʻi i ka pololei o ka hoʻopili ʻana a me ka hoʻopili ʻana o ka interface;
Ka hana ʻana i ka micro-sandblasting o ka seramika a me nā mea i hui pū ʻia: ka hana ʻana i ka ʻilikai e hoʻoikaika i ka ikaika o ka hoʻopaʻa ʻana.
I. Hōʻuluʻulu Manaʻo
Me ka hoʻomohala mau ʻana o ka ʻenehana oneblasting a me ka ʻoihana hana e neʻe ana i ka pololei kiʻekiʻe a me ka palekana o ke kaiapuni kiʻekiʻe, ʻaʻole hiki i nā mea oneblasting kuʻuna ke hoʻokō hou i nā pono o nā kaʻina hana kiʻekiʻe. ʻO ka silicon ʻeleʻele, ma ke ʻano he abrasive hana me ka ikaika kiʻekiʻe, ka noʻonoʻo haʻahaʻa, ka maʻemaʻe kiʻekiʻe a me ka palekana o ke kaiapuni, ke lilo nei i mea hoʻonui koʻikoʻi i ka ʻoihana oneblasting. Inā paha ma ka hana pololei, ka matte optical, a i ʻole ma ka hana ʻana i nā mea uila, ka pretreatment ʻili o nā lako aerospace a me nā kahua ʻē aʻe, ua hōʻike ka silicon ʻeleʻele i nā manaʻolana noi ākea.
