ʻO ka hoʻomohala wikiwiki ʻana i ka ʻike a me ka optoelectronics ua hāpai i ka hoʻomau mau ʻana o ka ʻenehana mechanical polishing (CMP).Ma waho aʻe o nā mea hana a me nā mea waiwai, ʻoi aku ka hilinaʻi o ka loaʻa ʻana o nā papa kiʻekiʻe kiʻekiʻe i ka hoʻolālā ʻana a me ka hana ʻana o nā ʻāpana abrasive kiʻekiʻe, a me ka hoʻomākaukau ʻana i ka slurry polishing e pili ana.A me ka hoʻomau ʻana o ka hoʻomaikaʻi ʻana i ka pololei o ka hoʻoili ʻana i ka ʻili a me nā koi pono, ʻoi aku ka kiʻekiʻe o nā koi no nā mea polishing kiʻekiʻe.Ua hoʻohana nui ʻia ʻo Cerium dioxide i ka mīkini pololei o ka ʻili o nā mea microelectronic a me nā ʻāpana optical precision.
ʻO ka Cerium oxide polishing powder (VK-Ce01) polishing powder he mau mea maikaʻi o ka hiki ke ʻoki ikaika, kiʻekiʻe polishing pono, kiʻekiʻe polishing pololei, maikaʻi polishing maikaʻi, maʻemaʻe ka hana ʻana, haʻahaʻa haʻahaʻa, lōʻihi ke ola lawelawe, etc., a hoʻohana nui ʻia i loko ʻO ka mākaʻikaʻi kikoʻī kikoʻī a me ka CMP, a me nā mea ʻē aʻe he kūlana koʻikoʻi.
Nā waiwai kumu o ka cerium oxide:
ʻO Ceria, i kapa ʻia ʻo cerium oxide, he oxide o ka cerium.I kēia manawa, ʻo ka valence o ka cerium ʻo +4, a ʻo ke kumu kemika ʻo CeO2.ʻO ka huahana maʻemaʻe he pauda kaumaha keʻokeʻo a i ʻole cubic crystal, a ʻo ka huahana haumia he melemele māmā a ʻulaʻula paha i ka pauka ʻulaʻula-ʻulaʻula (no ka mea, aia ka nui o ka lanthanum, praseodymium, etc.).Ma ka lumi wela a me ke kaomi, ʻo ceria kahi oxide paʻa o ka cerium.Hiki nō hoʻi i ka Cerium ke hana i ka +3 valence Ce2O3, ʻaʻole paʻa a hana ʻo CeO2 paʻa me O2.Hiki ke hoʻoheheʻe ʻia ka Cerium oxide i ka wai, ka alkali a me ka waikawa.ʻO 7.132 g/cm3 ka mānoanoa, ʻo ka helu hoʻoheheʻe he 2600 ℃, a ʻo ka helu hoʻolapalapa he 3500 ℃.
ʻO ka hana hoʻoliʻiliʻi o ka cerium oxide
ʻAʻole kiʻekiʻe ka paʻakikī o nā ʻāpana CeO2.E like me ka mea i hōʻike ʻia ma ka papa ma lalo nei, ʻoi aku ka haʻahaʻa o ka paʻakikī o ka cerium oxide ma mua o ka daimana a me ka alumini oxide, a haʻahaʻa hoʻi ma mua o ka zirconium oxide a me ka silicon oxide, ua like ia me ka ferric oxide.No laila, ʻaʻole hiki ke hoʻopau i nā mea i hoʻopaʻa ʻia i ka silicon oxide, e like me ke aniani silicate, ke aniani quartz, a me nā mea ʻē aʻe, me ka ceria me ka paʻakikī haʻahaʻa mai kahi ʻike mechanical wale nō.Eia nō naʻe, ʻo ka cerium oxide i kēia manawa ka pauka polishing makemake ʻia no ka hoʻoliʻiliʻi ʻana i nā mea i hoʻokumu ʻia i ka silicon oxide a i ʻole nā mea silicon nitride.Hiki ke ʻike ʻia he hopena ʻē aʻe ka hoʻoliʻi cerium oxide ma waho o nā hopena mechanical.ʻO ka paʻakikī o ka daimana, kahi mea wili a me ka poli hoʻohana maʻamau, loaʻa nā hakahaka o ka oxygen i ka lattice CeO2, e hoʻololi ana i kona mau kino kino a me nā mea kemika a loaʻa kekahi hopena i nā waiwai polishing.Loaʻa i nā pauka poʻi cerium oxide i hoʻohana mau ʻia i kekahi mau mea ʻokoʻa honua ʻokoʻa ʻē aʻe.Loaʻa i ka Praseodymium oxide (Pr6O11) kahi hoʻolālā cubic lattice i waena o ka maka, kūpono ia no ka hoʻoliʻiliʻi ʻana, aʻo nā lanthanide rare earth oxides ʻaʻohe hiki ke poli.Me ka hoʻololi ʻole ʻana i ke ʻano aniani o CeO2, hiki iā ia ke hana i kahi hopena paʻa me ia i loko o kahi ākea.No ka maʻemaʻe kiʻekiʻe nano-cerium oxide polishing pauda (VK-Ce01), ʻoi aku ka kiʻekiʻe o ka maʻemaʻe o ka cerium oxide (VK-Ce01), ʻoi aku ka nui o ka hiki ke polishing a me ka lōʻihi o ke ola o ka lawelawe ʻana, ʻoi aku hoʻi no nā aniani paʻa a me nā lens optical quartz no kahi. manawa lōʻihi.I ka cyclic polishing, he mea pono e hoʻohana kiʻekiʻe-maʻemaʻe cerium oxide polishing pauka (VK-Ce01).
No ka hoʻohana ʻana i ka pauka cerium oxide polishing:
ʻO Cerium oxide polishing powder (VK-Ce01), i hoʻohana nui ʻia no ka hoʻoliʻi ʻana i nā huahana aniani, ua hoʻohana nui ʻia ia i nā māla aʻe:
1. Makaaniani, lens lens poli;
2. ʻO ka leki uila, ke aniani aniani, ka lens, etc.;
3. Ke aniani pale kelepona paʻalima, ka ʻili kiaʻi (puka kiaʻi), etc.;
4. Mākaʻikaʻi ʻo LCD i nā ʻano pale LCD āpau;
5. Nā Rhinestones, nā daimana wela (nā kāleka, nā daimana ma nā jeans), nā pōpō kukui (nā chandelier nani i ka hale nui);
6. Nā mea hana kristal;
7. Ka poni hapa o ka jade
ʻO nā derivatives hoʻoliʻi cerium oxide i kēia manawa:
Hoʻopili ʻia ka ʻili o ka cerium oxide me ka alumini e hoʻomaikaʻi maikaʻi i kona poli ʻana i ke aniani optical.
Ke Keʻena ʻImi ʻenehana a me ka hoʻomohala ʻana o UrbanMines Tech.ʻO Limited, i manaʻo ʻia ʻo ka hoʻohui ʻana a me ka hoʻololi ʻana i ka ʻili o nā ʻāpana polishing nā ala nui a me nā ala e hoʻomaikaʻi ai i ka pono a me ka pololei o ka polishing CMP.No ka mea hiki ke hoʻopaʻa ʻia ka waiwai o nā ʻāpana e ka hui ʻana o nā mea he nui, a hiki ke hoʻomaikaʻi ʻia ka paʻa ʻana o ka dispersion a me ka pono polishing o ka slurry polishing e ka hoʻololi ʻana i ka ʻili.ʻO ka hoʻomākaukau a me ka hana polishing o ka pauka CeO2 doped me TiO2 hiki ke hoʻomaikaʻi i ka pono polishing e ʻoi aku ma mua o 50%, a i ka manawa like, ua hoʻemi ʻia nā hemahema o ka honua e 80%.ʻO ka hopena polishing synergistic o CeO2 ZrO2 a me SiO2 2CeO2 oxides composite;No laila, ʻo ka ʻenehana hoʻomākaukau o doped ceria micro-nano composite oxides he mea nui ia no ka hoʻomohala ʻana i nā mea polishing hou a me ke kūkākūkā ʻana o ka mīkini polishing.Ma waho aʻe o ka nui o ka doping, ʻo ka mokuʻāina a me ka hāʻawi ʻana i ka dopant i loko o nā ʻāpana synthesized e hoʻopilikia nui i kā lākou mau waiwai a me ka hana polishing.
I waena o lākou, ʻoi aku ka maikaʻi o ka synthesis o nā ʻāpana polishing me ka hoʻolālā cladding.No laila, he mea koʻikoʻi loa ke koho ʻana i nā ʻano hana synthetic a me nā kūlana, ʻoi aku ka maʻalahi o nā ʻano maʻalahi a me ke kumu kūʻai.Me ka hoʻohana ʻana i ka cerium carbonate hydrated ma ke ʻano he mea maka nui, ua hoʻohui ʻia nā mea hoʻoliʻiliʻi cerium oxide alumini-doped e ke ʻano mechanochemical wet solid-phase mechanochemical.Ma lalo o ka hana a ka ikaika mechanical, hiki ke hoʻokaʻawale i nā ʻāpana nui o ka cerium carbonate hydrated i loko o nā ʻāpana maikaʻi, ʻoiai ʻo ka alumini nitrate e hana me ka wai amonia e hana i nā ʻāpana colloidal amorphous.Hoʻopili maʻalahi nā ʻāpana colloidal i nā ʻāpana cerium carbonate, a ma hope o ka maloʻo ʻana a me ka calcination, hiki ke hoʻokō ʻia ka doping alumini ma ka ʻili o ka cerium oxide.Ua hoʻohana ʻia kēia ʻano hana e synthesize i nā ʻāpana cerium oxide me nā ʻano like ʻole o ka doping aluminika, a ua ʻike ʻia kā lākou hana polishing.Ma hope o ka hoʻohui ʻia ʻana o ka nui kūpono o ka alumini i ka ʻili o nā ʻāpana cerium oxide, e piʻi aʻe ka waiwai maikaʻi ʻole o ka ʻili o ka ʻili, a ʻo ia hoʻi ka mea i hoʻokaʻawale i waena o nā ʻāpana abrasive.ʻOi aku ka ikaika o ka electrostatic repulsion, e hoʻoikaika ana i ka hoʻomaikaʻi ʻana i ka paʻa ʻana o ka abrasive suspension.I ka manawa like, e hoʻoikaika pū ʻia ka adsorption like ma waena o nā ʻāpana abrasive a me ka papa palupalu i hoʻopiʻi maikaʻi ʻia ma o Coulomb attraction, i mea e pono ai ka launa pū ʻana ma waena o ka abrasive a me ka papa palupalu ma ka ʻili o ke aniani i hoʻonani ʻia. ka hoʻomaikaʻi ʻana i ka helu polishing.
