Wehewehena a me nā hiʻohiʻona

Wehewehe: Hoʻohana ʻo WNX i ka ʻenehana hana hana automated holomua a hoʻohana i nā mea maka kiʻekiʻe e hana i nā mea kiʻekiʻeʻO ka nui o nā ʻāpana Cerium Carbonate.

Nā Hiʻohiʻona Koʻikoʻi:

Maʻemaʻe Kiʻekiʻe:ʻO ka nui o nā ʻāpana Cerium Carbonate ʻaʻohe mea haumia mai nā mea honua laha ʻole (e like me ka hao, calcium, sodium), a haʻahaʻa ka nui o ka haumia.

Ka hoʻoheheʻe maikaʻi:ʻO ka nui o nā ʻāpana Cerium Carbonate hiki ke hoʻoheheʻe koke i ka wai a me nā waikawa ikaika.

Kūlike: ʻO ka hoʻokele puʻupuʻu koʻikoʻi i ka hana ʻana oʻO ka nui o nā ʻāpana Cerium Carbonate hōʻoia i ka maikaʻi paʻa no ka hana ʻana i ka ʻoihana nui.

Mea hoʻouluulu ʻoihana kemika: ʻO ka cerium carbonate ʻāpana nui kahi mea mua koʻikoʻi no ka hoʻomākaukau ʻana i nā mea hoʻouluulu ʻekolu ala no ka hoʻopau ʻana o ke kaʻa. Ma o ka calcination wela kiʻekiʻe, hiki ke hoʻololi ʻia i cerium oxide me ka hiki ke mālama i ka oxygen kiʻekiʻe, no laila e hoʻolaha pono ana i nā hopena hoʻomaʻemaʻe catalytic o ke kalapona monoxide, hydrocarbons, a me nā nitrogen oxides.

Mea Hoʻohemo Phosphorus Kūpono: Ma muli o ke kiʻekiʻe o ka pilina ma waena o nā ion cerium a me nā ion phosphate, hiki ke hoʻohana ʻia ka cerium carbonate ʻāpana nui ma ke ʻano he mea hoʻohemo phosphorus no ka mālama ʻana i ka wai a me ka hoʻihoʻi ʻana i nā kino wai eutrophic. ʻO kona nui o nā ʻāpana nui e hiki ai ke hana maikaʻi i ka sedimentation i nā noi hana, e hoʻomaʻamaʻa ana i ka hoʻokaʻawale ʻana a me ka hoʻōla ʻana, a e hōʻemi pono ana i ka nui o ka phosphorus i loko o ka effluent i kahi pae haʻahaʻa loa (e laʻa, mai 0.55 mg-P/L a i≤0.03 mg-P/L).

Nā Pālolo a me nā Mea Hana Hoʻopili: ʻO ka cerium carbonate nui kahi mea maka nui no ka hana ʻana i nā pālolo kūikawā (e like me nā pālolo uila) a me nā pauka hoʻopili hana kiʻekiʻe. ʻO kona nui o nā ʻāpana e kōkua i ka hoʻokō ʻana i kahi ʻili hoʻopili laumania, he mea nui ia i ka hoʻopili kemika mechanical (CMP) o ke aniani optical a me nā wafers semiconductor. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui i nā alloys paʻakikī e hoʻonui i ka hana o ka mea.

Nā mea waena o ka hoʻohuihui kemika: Ma ke ʻano he mea nui no nā hui cerium, hoʻohana ʻia ka cerium carbonate nui e hoʻohui i nā paʻakai cerium like ʻole (e like me ka cerium nitrate, cerium chloride, a me nā mea ʻē aʻe) a ma ka hopena e hoʻomākaukau i ka cerium oxide maʻemaʻe kiʻekiʻe. Ma ka hoʻomalu pono ʻana i nā kūlana ua (e like me ka nui o ka hopena honua laha ʻole, ka mahana o ka hopena, a me ka manawa ʻelemakule), hiki ke hoʻoponopono ʻia ka nui o ka ʻāpana o ka huahana (hiki i ka nui o ka ʻāpana waena D50 ke hiki i kahi 150μm), e hoʻokō ana i nā koi kikoʻī o nā noi ma lalo no ka nui o nā ʻāpana o nā mea maka.
