Hoʻomaka i nā huahana silika ʻeleʻele a me kā lākou noi i ka sandblasting
Silika ʻeleʻeleʻO ia kahi mea silika hana me kahi hoʻolālā ʻili kūikawā, i kapa ʻia no kona hiki ke hoʻoheheʻe māmā i ka māmā a me ka micro-nano surface morphology. I nā makahiki i hala iho nei, me ka hoʻomaikaʻi ʻana i ka pololei o ka mālama ʻana i ka ʻili a me nā pono hana i ka hana kiʻekiʻe, ua hoʻohana nui ʻia ka silika ʻeleʻele i nā photovoltaics, optoelectronics, semiconductors, optical component manufacturing a me nā māla ʻē aʻe me kāna mau waiwai kino a me nā kemika. I ka manawa like, ua komo mālie ka silikoni ʻeleʻele i ka ʻoihana sandblasting ili a ua lilo i ʻano hou o nā mea sandblasting me ka hana maikaʻi loa.
Ⅰ. ʻO nā hiʻohiʻona kumu o ka silikonʻeleʻele
Hoʻokumu ʻia ke kilika ʻeleʻele ma o ka mālama ʻana i ka ʻili kilika ma o nā ʻenehana hoʻomākaukau ʻenehana micro-nano (e like me ka reactive ion etching, metala-assisted chemical etching, laser-induced etching, etc.). Hōʻike kona ʻili i kahi cone paʻa a i ʻole ka hana columnar, hiki ke hōʻemi nui i ka noʻonoʻo ʻana o ka mālamalama. Hiki ke emi ma lalo o 1% ka mea hoʻomanaʻo i ka hui ʻike ʻia i ka infrared kokoke, no laila ʻeleʻele ke nānā aku.
ʻAʻole loaʻa i ka silikoni ʻeleʻele wale nā hiʻohiʻona optical maikaʻi, akā loaʻa nō hoʻi nā pono o ka paʻakikī kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, ke kūpaʻa ʻaʻahu, a me ka pale ʻana i ka corrosion. He ikaika a kūpono hoʻi no nā pōʻai he nui ma lalo o nā kūlana hopena kiʻekiʻe. ʻOi aku ka maikaʻi ma ka sandblasting ma mua o nā abrasives kuʻuna e like me ka corundum keʻokeʻo, ka corundum brown, ke one quartz, etc.
Ⅱ. ʻO nā pōmaikaʻi o ka silika ʻeleʻele i ka sandblasting
ʻO ka Sandblasting kahi ʻano hana lapaʻau e hoʻohana ana i ke kahe one kiʻekiʻe e hoʻopili i ka ʻili e hoʻomaʻemaʻe, hoʻoneʻe ʻia o ka papa oxide, hoʻokalakala a i ʻole nā hopena hoʻonaninani. Ma ke ʻano he abrasive kiʻekiʻe, ʻeleʻele ʻeleʻele nā mea maikaʻi i ke kahua o ka sandblasting:
1. ʻO ka hopena o ka ʻili maikaʻi a kūlike
ʻO ke ʻano geometric o nā ʻāpana silika ʻeleʻele maʻamau a paʻa ka morphology. Ma hope o ka pīpī ʻana, hiki iā ia ke hana i kahi hopena matte like ʻole ma 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 hana alumini alumini, a me nā mea ʻē aʻe i loaʻa nā koi kiʻekiʻe no ka kūlike o ka ʻili a me ka helehelena.
2. ʻO ka paʻakikī kiʻekiʻe a me ka hopena hopena
ʻO ka paʻakikī Mohs o ka silikonʻeleʻele he kiʻekiʻe e like me 8.5 a i luna paha, haʻahaʻa ka haki ʻana i ka wā o ka sandblasting, a lōʻihi ke ola lawelawe. Ke hoʻohālikelike ʻia me ke one quartz maʻamau a i ʻole nā pahu aniani, ʻoi aku ka maikaʻi o ka sandblasting silicon ʻeleʻele a ʻoi aku ka ikaika o ka hopena, a hiki ke hoʻopau i ka hoʻomaʻemaʻe hohonu a me ka ʻawaʻawa i ka manawa pōkole.
3. ʻO ka hoʻomaʻemaʻe kiʻekiʻe a me ka palekana kaiapuni
ʻOi aku ka maʻemaʻe o ka silika ʻeleʻele ma luna o 99%, a ʻaʻole i loko o nā mea haumia ʻino e like me ke silikona manuahi a me nā metala kaumaha. He haʻahaʻa haʻahaʻa lepo lepo i loko o ka hale hana sandblasting a kūpono loa ia no ka hoʻohana ʻana i nā ʻoihana hoʻomaʻemaʻe kiʻekiʻe e like me nā mea uila, nā mea lapaʻau, a me ka ʻeke semiconductor. I ka manawa like, paʻa kona ʻano ʻāpana, liʻiliʻi ka lepo lepo, a ʻoi aku ka palekana no ke olakino o nā mea hana.
4. Hiki ke hoʻohana hou ʻia a hiki ke mālama ʻia
Ma muli o kona paʻakikī kiʻekiʻe a me ka paʻa paʻa, hiki i ka silikonʻeleʻele ke hoʻomau i ka hopena maikaʻi ma hope o nā pōʻai he nui, e hōʻemi nui ana i ka poho waiwai. I nā lako sandblasting ʻakomi nui, ʻoi aku ka maikaʻi o ka hoʻokele waiwai.
Ⅲ. Nā wahi noi maʻamau
Ua hoʻohana nui ʻia ka ʻeleʻele ʻeleʻele sandblasting abrasives i nā kahua aʻe:
ʻO ka hoʻomaʻamaʻa pono ʻana i ka ʻaoʻao matte: e like me ke kelepona paʻa kiʻekiʻe ma waena o ke kiʻi kiʻekiʻe, ka pūpū puke, ka pūpū wati akamai a me nā huahana alumini alumini;
ʻO ka hoʻomaʻamaʻa ʻana i ke aniani aniani: hoʻohana ʻia no ka lens, kānana, optical window matte a me ka hoʻonaninani;
Aerospace a me nā ʻāpana pūʻali koa: wehe i ka papa oxide me ka ʻole o ka hoʻololi ʻana i ka nui e hoʻomaikaʻi ai i ka adhesion uhi;
Etching ili ili: hoʻomaikaʻi i ka hoʻopili pololei ʻana a me ka pili pili;
ʻO ka micro-sandblasting mea hoʻomaʻemaʻe a me ka mea i hui pū ʻia: ka hoʻomaʻamaʻa ʻana i ka ʻili e hoʻoikaika i ka ikaika paʻa.
Ⅳ. Hōʻuluʻulu manaʻo
Me ka hoʻomau mau ʻana o ka ʻenehana sandblasting a me ka ʻoihana hana e neʻe nei i ke kiʻekiʻe kiʻekiʻe a me ka ʻoi aku ka kiʻekiʻe o ka mālama ʻana i ke kaiapuni, ʻaʻole hiki ke hoʻokō hou nā mea sandblasting maʻamau i nā pono o nā kaʻina hana kiʻekiʻe. ʻO ka silikoni ʻeleʻele, ma ke ʻano he abrasive hana me ka ikaika kiʻekiʻe, ka noʻonoʻo haʻahaʻa, ka maʻemaʻe kiʻekiʻe a me ka pale ʻana i ke kaiapuni, ke lilo nei i mea hoʻonui koʻikoʻi i ka ʻoihana sandblasting. Inā ma ka hana pololei, optical matte, a i ʻole i ka hoʻoili ʻana i nā mea uila, ka hoʻomaʻamaʻa ʻana i ka ʻili o ka aerospace a me nā māla ʻē aʻe, ua hōʻike ʻia ka silika ʻeleʻele i nā manaʻo noiʻi ākea.
