Tsananguro & Zvimiro

Tsananguro: WNX inoshandisa tekinoroji yekugadzira otomatiki yepamusoro uye inoshandisa zvinhu zvemhando yepamusoro kugadzira mhando yepamusoroSaizi yezvikamu zvikuru Cerium Oxide.

Zvinhu Zvikuru:

Kuchena Kwakakwirira:Saizi yezvikamu zvikuru Cerium Oxide

haina tsvina inobva kuzvinhu zvisingawanzoitiki zvepanyika (zvakaita sesimbi, calcium, sodium), uye huwandu hwetsvina yacho hwakaderera.

Kunyunguduka Kwakanaka:Saizi yezvikamu zvikuru Cerium Oxide

inogona kunyungudika nekukurumidza mumvura uye acid yakasimba.

Kuenderana: Kutarisirwa kwakasimba kwehuwandu hwezvinhu mukugadzirwa kweSaizi yezvikamu zvikuru Cerium Oxide

inoita kuti pave nemhando yakagadzikana yekugadzira zvinhu mumaindasitiri makuru.

Zvinhu zvinokonzeresa indasitiri yemakemikari:Saizi yezvikamu zvikuru Cerium Oxide, nekuda kwesimba rayo repamusoro remakanika uye kugadzikana, inoshandiswa senzira yakanaka yekutakura zvinhu mumagetsi anogadziriswa anofanira kutsungirira kumanikidzwa kwakanyanya kana kukanganiswa nemhepo inomhanya nekukurumidza. Inogona kurodha simbi dzinokosha zvinobudirira (dzakadai seplatinum nepalladium) uye inoshandiswa mumabasa akadai sehydrogenation mumakemikari epetrochemicals, zvichiwedzera zvakanyanya hupenyu hwekushanda kwemagetsi. Hunhu hwayo hwakasiyana hwe oxygen vacancy defect hunoitawo kuti iite basa rakakosha mukuchenesa utsi hwemotokari (ma catalytic converters ane nzira nhatu), ichikurudzira kushandurwa kwe carbon monoxide (CO), hydrocarbons (HC), uye nitrogen oxides (NOx).

Mushonga wekubvisa Phosphorus muDziva:Saizi yezvikamu zvikuru Cerium Oxide Zvidimbu zvinogona kunyudza nekukonzera ma phosphate ions mumuviri wemvura, nokudaro zvichidzivisa kukura kwe algae uye kugadzirisa dambudziko re eutrophication mumuviri wemvura. Hukuru hwezvidimbu hwakakura, uye mashandiro azvo ekunyungudutsa ari nani mukushandiswa kwemuviri wemvura, zvichiita kuti zvive nyore kupora uye kuderedza njodzi yekusvibiswa kwechipiri.

Mabhatiri nezvinhu zveSimba: Muma solid oxide fuel cells (SOFCs),Saizi yezvikamu zvikuru Cerium Oxide inogona kushandiswa sechinhu chinoumba electrolyte. Kugadzikana kwayo kwakanyanya kunobatsira kuwedzera ionic conductivity uye kugara kwenguva refu kwebhatiri. Pamusoro pezvo, inogona zvakare kushandiswa sezvinhu zvekugadzira hydrogen storage alloys ye electrode isina kunaka yemabhatiri e nickel-hydrogen, kana kugadzirisa zvinhu zve lithium-ion battery electrode, nokudaro ichivandudza mashandiro ebhatiri kuburikidza nechimiro chayo chakagadzikana.

Zvinosanganisa kugadzirwa kwemakemikari:Saizi yezvikamu zvikuru Cerium Oxide chinhu chakakosha chekugadzira zvimwe zvinhu zvinoshanda zve cerium (zvakadai se cerium salts, doped cerium oxide, nezvimwewo). Kuburikidza nekuwedzera kugadziriswa kwemakemikari, inogona kushandurwa kuita cerium compounds ine ma morphology chaiwo uye hunhu, izvo zvinoshandiswa muminda yakaita se electronic ceramics uye ultraviolet absorption materials.
