Kugwiritsa ntchito Cerium oxide

Cerium Oxide, yomwe imatchedwanso Ceria, imagwiritsidwa ntchito kwambiri pamagalasi, zoumba ndi zopangira zopangira. M'makampani agalasi, imatengedwa kuti ndiyo njira yabwino kwambiri yopukutira magalasi pakupukuta bwino kwambiri. Amagwiritsidwanso ntchito kuyeretsa galasi posunga chitsulo mu ferrous state. Kutha kwa magalasi a Cerium-doped kutsekereza kuwala kwa ultra violet kumagwiritsidwa ntchito popanga zida zamagalasi azachipatala ndi mawindo apamlengalenga. Amagwiritsidwanso ntchito kuteteza ma polima kuti asade ndi kuwala kwa dzuwa komanso kupondereza magalasi a kanema wawayilesi kuti asasinthe. Amagwiritsidwa ntchito pazigawo za kuwala kuti apititse patsogolo ntchito. Kuyera kwakukulu Ceria amagwiritsidwanso ntchito mu phosphors ndi dopant to crystal.

Cerium oxide, yomwe imadziwikanso kuti ceria, ndi gulu lopangidwa ndi zinthu za cerium ndi okosijeni wokhala ndi chilinganizo chamankhwala CeO2. Ndi kuwala chikasu kapena woyera ufa, ndi okhazikika pansi zinthu bwino. Cerium oxide ili ndi ntchito zosiyanasiyana, kuphatikiza:

1. Catalyst: Cerium oxide imagwiritsidwa ntchito ngati chothandizira m'njira zambiri zamafakitale, monga m'makampani oyendetsa magalimoto kuti azitha kutembenuza mpweya kuti achepetse kutulutsa komanso kupanga mafuta opangira.

2. Polishing agent: Cerium oxide imagwiritsidwa ntchito ngati kupukuta kwa galasi ndi zipangizo zina. Ndiwothandiza kwambiri pakusalaza pamalo ovunda ndi kuchotsa zokala.

3. Chowonjezera chamafuta: Itha kugwiritsidwa ntchito ngati chowonjezera chamafuta kuti chilimbikitse kuyaka koyera komanso kothandiza kwambiri kwamafuta.

4. Makampani agalasi: Cerium oxide amagwiritsidwa ntchito mumakampani opanga magalasi kupanga magalasi apamwamba kwambiri chifukwa amatha kuwonjezera chiwonetsero cha refractive ndikuwonjezera kulimba kwa galasi.

5. Kupanga ma cell a dzuwa: Cerium oxide imagwiritsidwa ntchito ngati zokutira popanga ma cell a dzuwa. Ponseponse, cerium oxide ili ndi ntchito zambiri ndipo ndi yofunika kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera.

6.ogwiritsidwa ntchito ngati galasi decolorizing wothandizira ndi galasi kupukuta ufa. Amagwiritsidwanso ntchito ngati zopangira popanga zitsulo za cerium. Kuyeretsedwa kwakukulu Cerium dioxide ndikofunika kwambiri pakugwiritsa ntchito zipangizo za fulorosenti
