Yakazara Nhanganyaya uye Zvishandiso

Cerium chinhu chemakemikari nechiratidzo cheCE uye ATOMIC nhamba 58. Iyo inhengo yeLanthanide Series uye ndiyo inonyanya kuwanda uye inoshandiswa zvakanyanya nezvinhu zvisingawanzoitika pasi.
Zvivakwa: Cerium yakasviba, silvery, uye simbi inovhenekera iyo inoshanda zvakanyanya uye nyore oxdize mumhepo. Iyo ine nzvimbo yakaderera yekunyungudika uye yakanaka cittor yemagetsi. Cerium inozivikanwawo nekuda kwekugona kwayo kwekugona kushanduka-shanduka shanduko mune yayo oxidation mamiriro, iyo inoita kuti ive inoshanda mune dzakasiyana siyana dzekushandisa.

Zvishandiso:Cerium inoshandiswa mune yakasarudzika yezvigadzirwa nekuda kwezvivakwa zvayo zvakasarudzika. Zvimwe zvakakosha zvikumbiro zvinosanganisira:
1.CatalyStts:Cerium oxide inowanzoshandiswa seyakaringana mumitambo yakawanda yemakemikari, senge emagetsi emagetsi ekutsigira, mashandiro emumaindasitiri ekudzora, uye masero mafuta. Iyo inobatsira mukusimudzira kunaka kwekurovera uye kuderedza zvinokuvadza polutants
2.Girazi uye kupukuta:Cerium oxide inoshandiswa zvakanyanya mukugadzira girazi, kunyanya yegirazi polising. Iyo inowedzerwa kune egirazi mafomu ekuvandudza zvivakwa zvaro, index inodzora, uye inokwenenzvera kuramba. Iyo inoshandiswawo mukugadzirwa kweiyo chaiyo optics, magirazi, uye lens
3.Ceramics:Cerium comalound inoshandiswa mukugadzirwa kwe cramic zvinhu. Ivo vanopa kuvandudzwa simba, kusimba, uye kupisa kupokana, kuita kuti vabatsire mune dzakasiyana-siyana zvikumbiro senge ceramic capacitors, spark plugs, uye yakasimba mapundu, uye yakasimba oxide mafuta masero
4.Metal Alloys:Cerium inoshandiswa sechinhu chinokwezva mukugadzira madhiri akakosha, senge magnesium alloys. Aya mafirita anoratidza zvivakwa zvakavandudzwa senge yakawedzera simba, yakaderedzwa kupisa, uye yakawedzera yakakwirira-tembiricha kugadzikana
5.Hydrogen chengetedza:Cerium comalound ane kugona kutora uye kusunungura hydrogen kune mwero kupisa. Ichi chivakwa chakaita kuti utsvagurudzo uye udzorere zvechisimba-zvakavakirwa zvinhu zvekushandisa hydrogen zvekuchengetedza.
6.Fettilizer:Cerium compound, senge cerium sulfate, anoshandiswa mukurima sevarimi. Ivo vanobatsira mukuwedzera zvibereko zvezvirimwa, kuvandudza ivhu rine ivhu, uye kuderedza kurasikirwa kwemutengesi.
Kuchengetedza: Nepo cerium inowanzoonekwa seyakachengeteka, makomisheni ayo anofanira kubatwa nekuchenjera. Dzimwe cerium comalound inogona kuve ine chepfu uye inogona kukonzera kushatirisa kana kusekesa kana kuonana. Zviyero zvakanaka zvekuchengetedza zvinofanirwa kuteverwa kana uchishanda ne cerium.
Mukupedzisa, cerium chinhu chakakosha uye chakakosha uye chakakosha zvinoshandiswa pakubata, girazi kugadzira, ceramics, alloys, hydrogen kuchengetedza, uye kurima. Zvivakwa zvaro zvakasarudzika zvinoita kuti zvive zvakakosha mumaindasitiri akasiyana-siyana, zvinopa mukufamba kwehunyanzvi uye kwekutsigira kwezvakatipoteredza.
