Tsananguro & Zvimiro

Tsananguro: WNX inoshandisa tekinoroji yekugadzira otomatiki yepamusoro uye inoshandisa zvinhu zvemhando yepamusoro kugadzira mhando yepamusoroCerium Oxide.

Zvinhu Zvikuru:

Kuchena Kwakakwirira:Cerium Oxide haina tsvina inobva kuzvinhu zvisingawanzoitiki zvepanyika (zvakaita sesimbi, calcium, sodium), uye huwandu hwetsvina yacho hwakaderera.

Kunyunguduka Kwakanaka:Cerium Oxide inogona kunyungudika nekukurumidza mumvura uye acid yakasimba.

Kuenderana: Kutarisirwa kwakasimba kwehuwandu hwezvinhu mukugadzirwa kweCerium Oxide inoita kuti pave nemhando yakagadzikana yekugadzira zvinhu mumaindasitiri makuru.

Kupukuta nemazvo: Cerium oxide ndiyo inonyanya kushanda pakupukuta girazi, inoshandiswa zvakanyanya mukugadzirisa malenzi ekamera, malenzi ekuona, zvishandiso zvemaziso, mawafer e semiconductor (chemical mechanical polishing CMP), nezvimwewo. Inogona kukurumidza kuita kuti nzvimbo yacho ive yakapfava zvikuru kuburikidza nekushanda kwemakemikari nemabasa emakanika.

Kugadziriswa Kwezvakatipoteredza: Mukuchenesa utsi hwemotokari (chinoshandura utsi hwemotokari nenzira nhatu), cerium oxide inoshanda sechinhu chakakosha, ichichengetedza nekuburitsa okisijeni zvinobudirira, zvichiita kuti carbon monoxide (CO), hydrocarbons (HC), uye nitrogen oxides (NOx) ishandurwe kuita carbon dioxide, nitrogen, nemvura isingakuvadzi. Inoshandiswawo mukurapa utsi hwemotokari uye kuchinja kwegasi remvura, pakati pezvimwe.

Indasitiri yeGirazi: Mukugadzirwa kwegirazi, cerium oxide inoita mabasa akawanda: (1) Chinhu chinobatsira pakucheneswa kweganda: Chinooxidisa maion egirini ane divalent iron ari mugirazi kupinda mumaion esimbi ane trivalent iron akareruka, zvichiita kuti girazi rive pachena; (2) Chinhu chinobatsira pakucheneswa kweganda: Chinobvisa mabubbles kubva mugirazi rakanyungudutswa; (3) Chinhu chinodzivirira UV: Chinoomesa mwaranzi ye ultraviolet uye chinoshandiswa kugadzira magirazi anodzivirira zuva nemahwindo emuchadenga. Chinogonawo kusanganiswa ne titanium dioxide kuti ipe ruvara mugirazi.

Simba neMagetsi: Nekuda kwekushanda kwayo kweionic uye kugadzikana, cerium oxide chinhu chakakosha che electrolyte kune ma solid oxide fuel cells (SOFCs). Mumunda wemagetsi, inoshandiswa kugadzira zvinhu zvemagetsi zveceramic zvakaita se capacitors ne piezoelectric ceramics.
