Noiʻi ʻana i ka hoʻohana ʻana o ka pauka Zirconia i ka poli ʻana i ka presisi kiʻekiʻe
Me ka wikiwiki o ka hoʻomohala ʻana o nā ʻoihana ʻenehana kiʻekiʻe e like me nā mea uila a me ka ʻenehana ʻike, ka hana ʻana opitika, nā semiconductors, a me nā keramika holomua, ke kau ʻia nei nā koi kiʻekiʻe ma luna o ka maikaʻi o ka hana ʻana i ka ʻili o nā mea. Ma ke ʻano kūikawā, i ka mīkini ʻana i nā ʻāpana koʻikoʻi e like me nā substrates sapphire, ke aniani optical, a me nā pā paʻa paʻa, ʻo ka hana o ka mea polishing e hoʻoholo pololei i ka pono o ka mīkini a me ka maikaʻi o ka ʻili hope loa.Pauka Zirconia (ZrO₂), kahi mea inorganic hana kiʻekiʻe, ke puka mālie nei i ke kahua o ka polishing pololei kiʻekiʻe ma muli o kona paʻakikī maikaʻi loa, kūpaʻa wela, kūpaʻa ʻaʻahu, a me nā waiwai polishing, e lilo ana i ʻelele o ka hanauna hou o nā mea polishing ma hope o ka cerium oxide a me ka alumini oxide.
I. Nā Waiwai Mea oPauka Zirconia
He pauka keʻokeʻo ka Zirconia me kahi kiko heheʻe kiʻekiʻe (ma kahi o 2700°C) a me nā ʻano ʻano kristal like ʻole, me nā ʻano monoclinic, tetragonal, a me cubic. Hiki ke loaʻa ka pauka zirconia paʻa a paʻa hapa paha ma ka hoʻohui ʻana i nā nui kūpono o nā mea hoʻopaʻa (e like me ka yttrium oxide a me ka calcium oxide), e ʻae ana iā ia e mālama i ke kūpaʻa pae maikaʻi loa a me nā waiwai mechanical ʻoiai i nā mahana kiʻekiʻe.
Pauka ZirconiaʻIke nui ʻia nā pono koʻikoʻi o ka ʻAhahui ma nā ʻano penei:
Paʻakikī kiʻekiʻe a me ka hiki ke hoʻopili maikaʻi loa: Me ka paʻakikī Mohs o 8.5 a i ʻole ma luna, kūpono ia no ka hoʻopili hope ʻana o nā ʻano mea paʻakikī like ʻole.
Paʻa kemika ikaika: Noho paʻa ia i nā wahi waikawa a i ʻole ka alkaline iki a ʻaʻole i maʻalahi i nā hopena kemika.
Ka hoʻopuehu maikaʻi loa: Hoʻololi ʻia ka nui o ka nano- a i ʻole ka submicronnā pauka zirconiahōʻike i ka hoʻokuʻu maikaʻi loa a me ke kahe ʻana, e kōkua ana i ka hoʻopili like ʻana.
ʻO ke alakaʻi wela haʻahaʻa a me ka pōʻino haʻahaʻa haʻahaʻa: ʻO ka wela i hana ʻia i ka wā o ka polishing he mea liʻiliʻi ia, e hōʻemi pono ana i ke kaumaha wela a me ka pilikia o nā microcracks ma ka ʻili i hana ʻia.
II. Nā Hoʻohana Maʻamau o ka Pauka Zirconia i ka Polishing Precision
1. Ka Polishing ʻana o ka Sapphire Substrate
ʻO nā kristal sapphire, ma muli o ko lākou paʻakikī kiʻekiʻe a me nā waiwai optical maikaʻi loa, hoʻohana nui ʻia i nā ʻāpana LED, nā aniani uaki, a me nā mea optoelectronic. ʻO ka pauka Zirconia, me kona paʻakikī like a me ka helu hōʻino haʻahaʻa, he mea kūpono ia no ka polishing mechanical chemical (CMP) o ka sapphire. Ke hoʻohālikelike ʻia me nā kuʻunanā pauka hoʻowali alumini oxide, hoʻomaikaʻi nui ka zirconia i ka pālahalaha o ka ʻili a me ka hoʻopau ʻana o ke aniani me ka mālama ʻana i nā helu wehe mea, e hōʻemi ana i nā ʻōpala a me nā microcracks.
2. Hoʻowali aniani ʻōlinolino
I ke kaʻina hana ʻana o nā ʻāpana optical e like me nā aniani kikoʻī kiʻekiʻe, nā prism, a me nā alo hope fiber optical, pono nā mea hoʻopili e hoʻokō i nā koi hoʻomaʻemaʻe a me ka maikaʻi loa. Ke hoʻohana nei i ka maʻemaʻe kiʻekiʻepauka zirconium oxideme ka nui o ka ʻāpana i kāohi ʻia o 0.3-0.8 μm ma ke ʻano he mea hoʻopili hope loa e hoʻokō ai i ka ʻoʻoleʻa ʻili haʻahaʻa loa (Ra ≤ 1 nm), e hoʻokō ana i nā koi "kīnā ʻole" koʻikoʻi o nā mea optical.
3. Ka Hana ʻana i ka Pā Paʻa Paʻa a me ka Silicon Wafer
Me ka hoʻonui mau ʻana o ka nui o ka mālama ʻikepili, ke lilo nei nā koi no ka pālahalaha o ka ʻili o ka pā paʻakikī i mea paʻakikī.Pauka Zirconia, i hoʻohana ʻia i ke kahua polishing maikaʻi o nā ʻili pā paʻakikī, kaohi pono ʻana i nā hemahema hana, hoʻomaikaʻi i ka pono kākau disk a me ke ola lawelawe. Eia kekahi, i ka polishing ultra-precision o nā wafers silicon, hōʻike ka zirconium oxide i ka hoʻohālikelike ʻili maikaʻi loa a me nā waiwai pohō haʻahaʻa, e lilo ia i mea koho e ulu ana i ka ceria.
I. Ka hopena o ka nui o ka ʻāpana a me ka kaohi hoʻopuehu ʻana i nā hopena poli ʻana
ʻO ka hana polishing o ka pauka zirconium oxide e pili pono ana ʻaʻole wale i kona paʻakikī kino a me ke ʻano kristal, akā ua hoʻopilikia nui ʻia hoʻi e kona hoʻolaha ʻana a me ka hoʻopuehu ʻana o ka nui o nā ʻāpana.
Ka Mana ʻana i ka Nui o nā ʻĀpana: Hiki i nā nui nui o nā ʻāpana ke hana maʻalahi i nā ʻōpala o ka ʻili, ʻoiai hiki i ka liʻiliʻi ke hōʻemi i ka wikiwiki o ka wehe ʻana i nā mea. No laila, hoʻohana pinepine ʻia nā micropowders a i ʻole nā nanopowders me kahi pae D50 o 0.2 a 1.0 μm e hoʻokō i nā koi hana like ʻole.
Hana Hoʻopuehu: ʻO ka hoʻopuehu maikaʻi ʻana e pale aku i ka hōʻuluʻulu ʻana o nā ʻāpana, e hōʻoia i ke kūpaʻa o ka hopena polishing, a hoʻomaikaʻi i ka pono o ka hana ʻana. ʻO kekahi mau pauka zirconia kiʻekiʻe, ma hope o ka hoʻololi ʻana i ka ʻili, hōʻike i nā waiwai hoʻokuʻu maikaʻi loa i loko o nā hopena wai a i ʻole nā waikawa nāwaliwali, e mālama ana i ka hana paʻa no nā hola he nui.
IV. Nā ʻAno Hoʻomohala a me ka Nānā i ka Wā E Hiki Mai Ana
Me ka holomua mau o ka ʻenehana nanofabrication,nā pauka zirconiake hoʻonui ʻia nei i ka maʻemaʻe kiʻekiʻe, ka hoʻolaha ʻana o ka nui o nā ʻāpana, a me ka hoʻonui ʻia ʻana o ka dispersibility. Pono ka nānā ʻana i nā wahi aʻe i ka wā e hiki mai ana:
1. Hana Nui a me ka Hoʻonui ʻana i ke Kumukūʻai o Nano-ScaleNā Pauka Zirconia
ʻO ke kamaʻilio ʻana i ke kumukūʻai kiʻekiʻe a me ke kaʻina hana paʻakikī o ka hoʻomākaukau ʻana i nā pauka maʻemaʻe kiʻekiʻe ke kī i ka hoʻolaha ʻana i kā lākou noi ākea.
2. Hoʻomohala ʻana i nā Mea Polishing Composite
ʻO ka hui pū ʻana o ka zirconia me nā mea e like me ka alumina a me ka silica e hoʻomaikaʻi i nā helu wehe a me nā mana kaohi ʻili.
3. ʻŌnaehana Wai Polishing ʻŌmaʻomaʻo a me ke Kaiapuni
E hoʻomohala i nā pāpaho hoʻopuehu biodegradable a me nā mea hoʻohui ʻaʻohe ʻawahia e hoʻonui ai i ke aloha i ke kaiapuni.
V. Hopena
Pauka ʻokikene Zirconium, me kona mau waiwai waiwai maikaʻi loa, ke pāʻani nei i kahi hana koʻikoʻi i ka polishing pololei kiʻekiʻe. Me ka holomua mau ʻana i ka ʻenehana hana a me ka piʻi ʻana o ke koi ʻoihana, ʻo ka hoʻohana ʻana opauka zirconium oxidee lilo ia i mea laha nui, a ua manaʻo ʻia e lilo i kākoʻo koʻikoʻi no ka hanauna e hiki mai ana o nā mea hoʻopili hana kiʻekiʻe. No nā ʻoihana pili, ʻo ka mālama ʻana i nā ʻano hoʻonui mea a me ka hoʻonui ʻana i nā noi kiʻekiʻe i ke kahua hoʻopili ʻana he ala nui ia e hoʻokō ai i ka ʻokoʻa huahana a me ke alakaʻi ʻenehana.
