Kodi cerium oxide ndi chiyani? Kodi ntchito zake ndi zotani?

Cerium oxide, amadziwikanso kuticerium dioxide, ali ndi dongosolo la mamolekyuCeO2. Angagwiritsidwe ntchito ngati zipangizo kupukuta, chothandizira, absorbers UV, electrolytes selo mafuta, absorbers magalimoto utsi, ziwiya zadothi pakompyuta, etc.

Ntchito yaposachedwa mu 2022: Mainjiniya a MIT amagwiritsa ntchito zoumba kuti apange ma cell amafuta a glucose kuti azitha kugwiritsa ntchito zida zobzalidwa m'thupi. Electrolyte ya cell yamafuta a glucose iyi imapangidwa ndi cerium dioxide, yomwe imakhala ndi ma ion conductivity apamwamba komanso mphamvu zamakina ndipo imagwiritsidwa ntchito kwambiri ngati electrolyte yama cell amafuta a haidrojeni. Cerium dioxide yatsimikiziridwanso kukhala biocompatible

Kuphatikiza apo, gulu lofufuza za khansa likuphunzira mwachangu za cerium dioxide, zomwe ndi zofanana ndi zirconia zomwe zimagwiritsidwa ntchito popanga mano ndipo zimakhala ndi biocompatibility ndi chitetezo.

· Osowa dziko kupukuta zotsatira

Ufa wonyezimira wapadziko lapansi wosowa uli ndi ubwino wothamanga mofulumira, kusalala kwambiri, ndi moyo wautali wautumiki. Poyerekeza ndi ufa wopukutira wachikhalidwe - ufa wofiira wachitsulo, suipitsa chilengedwe ndipo ndi wosavuta kuchotsa ku chinthu chotsatira. Kupukuta mandala ndi cerium oxide polishing powder kumatenga mphindi imodzi kuti kumalize, pomwe kugwiritsa ntchito iron oxide polishing powder kumatenga mphindi 30-60. Chifukwa chake, ufa wonyezimira wapadziko lapansi wosowa uli ndi ubwino wa mlingo wochepa, liwiro lopukuta mofulumira, komanso kupukuta kwakukulu. Ndipo zikhoza kusintha khalidwe kupukuta ndi malo ntchito.

Iwo m'pofunika kugwiritsa ntchito mkulu cerium kupukuta ufa kwa magalasi kuwala, etc; Low cerium kupukuta ufa chimagwiritsidwa ntchito galasi kupukuta magalasi lathyathyathya, chithunzi chubu galasi, magalasi, etc.

· Kugwiritsa ntchito ma catalysts

Cerium dioxide sikuti imakhala ndi ntchito yapadera yosungiramo okosijeni ndi kutulutsa, komanso ndiyomwe imathandizira kwambiri pamtundu wosowa padziko lapansi wa oxide. Ma Electrodes amatenga gawo lofunikira pakuchita kwa electrochemical m'maselo amafuta. Electrodes sikuti ndi gawo lofunikira komanso lofunikira la maselo amafuta, komanso limathandizanso kuti pakhale ma electrochemical reaction. Chifukwa chake, nthawi zambiri, cerium dioxide angagwiritsidwe ntchito ngati chowonjezera kuti apititse patsogolo magwiridwe antchito a chothandizira.

· Amagwiritsidwa ntchito pazinthu zoyamwitsa UV

Mu zodzoladzola zapamwamba kwambiri, nano CeO2 ndi SiO2 zokutira pamwamba zimagwiritsidwa ntchito ngati zida zazikulu zoyamwa ndi UV kuti zigonjetse zovuta za TiO2 kapena ZnO yokhala ndi mtundu wotumbululuka komanso kutsika kwa mayamwidwe a UV.

Kuphatikiza pakugwiritsa ntchito zodzoladzola, nano CeO2 imathanso kuwonjezeredwa ku ma polima kuti akonzekere ulusi wosakalamba wa UV, zomwe zimapangitsa kuti pakhale nsalu zamakemikolo zokhala ndi UV wabwino kwambiri komanso ma radiation oteteza kutentha. Kuchita kwake ndikwapamwamba kuposa TiO2, ZnO, ndi SiO2 yomwe imagwiritsidwa ntchito pano. Kuphatikiza apo, nano CeO2 imathanso kuwonjezeredwa ku zokutira kuti mupewe cheza cha ultraviolet ndikuchepetsa ukalamba ndi kuwonongeka kwa ma polima.
