ʻO ka hoʻomākaukau ʻana o ka pauka yttrium oxide

Hoʻohana pinepine ʻia ke ʻano o ka ua wai no ka hoʻomākaukau ʻana i nā oxides honua, ʻo ia ka mea e komo pū ai me ke ʻano o ka ua oxalate, ke ʻano o ka ua o ka ammonium bicarbonate, ke ʻano o ka urea hydrolysis a me ke ʻano o ka ua. Eia kekahi, ʻo ka spray granulation kekahi ala hoʻomākaukau i manaʻo nui ʻia i kēia manawa. Ke ʻano o ka ua paʻakai

1. ke ano o ka ua oxalate

ʻO ka ʻokiʻoki o ka honua laʻa i hoʻomākaukau ʻia e ke ʻano o ka ua oxalate ua loaʻa nā mea maikaʻi o ke kiʻekiʻe crystallization degree, ʻano aniani maikaʻi, ka wikiwiki kānana wikiwiki, haʻahaʻa haʻahaʻa haumia a me ka hana maʻalahi, ʻo ia ke ʻano maʻamau no ka hoʻomākaukau ʻana i ka wai hoʻomaʻemaʻe kiʻekiʻe o ka honua oxide i ka hana ʻoihana.

ʻO ke ʻano o ka ua ʻo Ammonium bicarbonate

2. ʻO ke ʻano o ka ua bicarbonate ammonium

ʻO ka ammonium bicarbonate kahi mea hoʻoheheʻe maʻalahi. I ka wā ma mua, hoʻohana pinepine ka poʻe i ke ʻano hoʻokahe ammonium bicarbonate no ka hoʻomākaukau ʻana i ka carbonate honua laha ʻole mai ka hoʻoheheʻe ʻana i ka wai o ka ʻeleʻele. I kēia manawa, hoʻomākaukau ʻia nā oxides honua e ka ammonium bicarbonate precipitation method i ka ʻoihana. ʻO ka maʻamau, ʻo ke ʻano o ka hoʻoheheʻe ammonium bicarbonate e hoʻohui i ka ammonium bicarbonate solid a i ʻole ka hopena i loko o ka hopena o ka honua chloride ma kahi mahana, Ma hope o ka ʻelemakule, holoi, hoʻomaloʻo a me ka puhi ʻana, loaʻa ka oxide. Eia nō naʻe, ma muli o ka nui o nā puʻupuʻu i hana ʻia i ka wā o ka ua o ka ammonium bicarbonate a me ka waiwai pH paʻa ʻole i ka wā o ka hopena o ka ua, wikiwiki a lohi paha ka nucleation rate, ʻaʻole kūpono i ka ulu aniani. No ka loaʻa ʻana o ka oxide me ka nui o ka nui a me ka morphology, pono e hoʻomalu pono ʻia nā kūlana hopena.

3. Urea ua

Hoʻohana nui ʻia ke ʻano o ka ua ʻana o ka Urea i ka hoʻomākaukau ʻana i ka oxide earth oxide, ʻaʻole ia he mea maʻalahi a maʻalahi hoʻi e hana, akā hiki nō hoʻi ke hoʻokō i ka mana kūpono o ka nucleation precursor a me ka ulu ʻana o ka particle, no laila ua ʻoi aku ka nui o ka poʻe. ʻoluʻolu a hoʻokipa nui i ka nānā ʻana a me ka noiʻi ʻana mai nā loea he nui i kēia manawa.

4. E kāpīpī i ka granulation

Loaʻa i ka ʻenehana spray granulation nā pono o ka automation kiʻekiʻe, ka hana kiʻekiʻe a me ka maikaʻi o ka pauka ʻōmaʻomaʻo, no laila ua lilo ka spray granulation i mea maʻamau i hoʻohana ʻia i ka pauka granulation.

I nā makahiki i hala iho nei, ʻaʻole i loli maoli ka hoʻohana ʻana i ka honua laʻa i nā kula kuʻuna, akā ua hoʻonui ʻia kona noi ʻana i nā mea hou. Ma ke ʻano he mea hou, nano Y₂O₃loaʻa i kahi kahua noi ākea. I kēia mau lā, nui nā ala e hoʻomākaukau ai i ka nano Y₂O₃nā mea waiwai, hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻāpana: ʻo ke ʻano o ka wai, ke ʻano o ke kinoea a me ke ʻano paʻa paʻa, ma waena o ke ʻano o ka wai ka mea i hoʻohana nui ʻia. Ua māhele ʻia lākou i ka pyrolysis spray, hydrothermal synthesis, microemulsion, sol-gel, combustion synthesis a me ka ua. Eia nō naʻe, ʻoi aku ka kiʻekiʻe o nā nanoparticles yttrium oxide i ʻoi aku ka kiʻekiʻe o ka ʻili, ka ikehu o ka ʻili, ka maikaʻi o ka wai a me ka dispersity, pono ke nānā aku.
