Nano ceriandi yotchipa komanso yogwiritsidwa ntchito kwambiriosowa nthaka okusayidindi tinthu tating'ono kukula, yunifolomu tinthu kukula kugawa, ndi mkulu chiyero. Insoluble m'madzi ndi alkali, sungunuka pang'ono mu asidi. Itha kugwiritsidwa ntchito ngati zida zopukutira, zopangira, zonyamulira zonyamula (zowonjezera), zotulutsa zotulutsa zamagalimoto, zowukira ma ultraviolet, ma electrolyte amagetsi, zida zamagetsi zamagetsi, etc. Nanoscale ceria imatha kukhudza mwachindunji magwiridwe antchito, monga kuwonjezera ultrafine nano ceria ku ceramics. , zomwe zingachepetse kutentha kwa sintering za ceramics, kulepheretsa kukula kwa lattice, ndi kupititsa patsogolo kachulukidwe wa zadothi. Dera lalikulu lapadera limatha kupititsa patsogolo ntchito yothandiza ya chothandizira. Makhalidwe ake osinthika a valence amamupatsa zinthu zabwino kwambiri za optoelectronic, zomwe zimatha kupangidwa ndi zida zina za semiconductor kuti zisinthidwe, kuwongolera bwino kwa kusamuka kwa photon, ndikuwongolera kutulutsa kwazinthuzo.
Amagwiritsidwa ntchito pa kuyamwa kwa UV
Malinga ndi kafukufuku, kuwala kwa ultraviolet kuyambira 280nm mpaka 320nm kungayambitse khungu, kupsa ndi dzuwa, ngakhale khansa yapakhungu pazovuta kwambiri. Kuonjezera nanoscale cerium oxide ku zodzoladzola kumachepetsa kuvulaza kwa ultraviolet poizoni m'thupi la munthu. Nano cerium oxide imakhala ndi mphamvu yoyamwa kwambiri pa cheza cha ultraviolet ndipo imatha kugwiritsidwa ntchito ngati chotengera cha ultraviolet pazinthu monga zodzoladzola zodzitetezera ku dzuwa, magalasi agalimoto, ulusi woteteza dzuwa, zokutira, mapulasitiki, ndi zina zambiri. kuyamwa kwa kuwala kowoneka bwino, kufalikira kwabwino, komanso chitetezo chabwino cha UV; Komanso, kupaka amorphous silicon okusayidi pa cerium okusayidi kungachepetse ntchito yake yothandiza, potero kulepheretsa kusinthika ndi kuwonongeka kwa zodzoladzola zomwe zimayambitsidwa ndi chothandizira cha cerium oxide.
Ntchito zothandizira
M’zaka zaposachedwapa, ndi kusintha kwa moyo wa anthu, magalimoto afala kwambiri m’miyoyo ya anthu. Pakali pano, magalimoto amawotcha mafuta a petulo. Izi sizingapewe kutulutsa mpweya woipa. Pakadali pano, zinthu zopitilira 100 zasiyanitsidwa ndi utsi wagalimoto, zomwe zopitilira 80 ndi zinthu zowopsa zomwe zidalengezedwa ndi makampani aku China oteteza zachilengedwe, makamaka kuphatikiza mpweya wa monoxide, ma hydrocarbons, nitrogen oxides, particulate matter (PM), etc. , kupatulapo nayitrogeni, mpweya, ndi zinthu zoyaka moto monga mpweya woipa wa carbon dioxide ndi nthunzi wamadzi, zomwe zili zopanda vuto, zigawo zina zonse ndi zovulaza. Chifukwa chake, kuwongolera ndi kuthetsa kuipitsidwa kwa utsi wamagalimoto kwakhala vuto lachangu lomwe likuyenera kuthetsedwa.
Ponena za zopangira utsi wamagalimoto, zitsulo zambiri zomwe anthu ankagwiritsa ntchito m’masiku oyambirira zinali chromium, mkuwa, ndi faifi tambala, koma zopinga zake zinali kutentha kwambiri kwa kutentha, kutengeka ndi chiphe, ndi kusachita bwino kothandizira. Pambuyo pake, zitsulo zamtengo wapatali monga platinamu, rhodium, palladium, ndi zina zotero zinagwiritsidwa ntchito monga chothandizira, zomwe zili ndi ubwino monga moyo wautali, ntchito zapamwamba, ndi zotsatira zabwino zoyeretsa. Komabe, chifukwa cha mtengo wapamwamba komanso mtengo wazitsulo zamtengo wapatali, zimakhalanso ndi poizoni chifukwa cha phosphorous, sulfure, lead, etc., zomwe zimapangitsa kuti zikhale zovuta kulimbikitsa.
Kuonjezera nano ceria pazitsulo zoyeretsera utsi wamagalimoto kuli ndi ubwino wotsatirawu poyerekeza ndi kuwonjezera pa nano ceria: gawo lenileni la nano ceria ndi lalikulu, kuchuluka kwa zokutira ndikwambiri, zomwe zili ndi zonyansa ndizochepa, ndipo mphamvu yosungiramo mpweya ndi. kuchuluka; Nano ceria ali pa nanoscale, kuonetsetsa mkulu enieni pamwamba m'dera chothandizira mu mkulu-kutentha mlengalenga, potero bwino kwambiri chothandizira ntchito; Monga chowonjezera, imatha kuchepetsa kuchuluka kwa platinamu ndi rhodium yomwe imagwiritsidwa ntchito, imangosintha kuchuluka kwamafuta a mpweya ndi zotsatira zothandizira, ndikuwongolera kukhazikika kwamafuta ndi mphamvu zamakina za chonyamulira.
Ikugwiritsidwa ntchito kumakampani azitsulo
Chifukwa cha mawonekedwe ake apadera a atomiki ndi zochitika zake, zinthu zapadziko lapansi zosowa zitha kugwiritsidwa ntchito ngati zowonjezera muzitsulo, chitsulo chosungunula, aluminiyamu, faifi tambala, tungsten ndi zida zina kuti athetse zonyansa, yeretsani mbewu ndikuwongolera kapangidwe kazinthu, potero kukonza makina, thupi ndi zinthu zina. processing katundu aloyi, ndi kupititsa patsogolo bata matenthedwe ndi dzimbiri kukana aloyi. Mwachitsanzo, m'makampani azitsulo, nthaka zosawerengeka monga zowonjezera zimatha kuyeretsa chitsulo chosungunula, kusintha maonekedwe ndi kugawa zonyansa pakati pazitsulo, kuyeretsa mbewu, ndikusintha mapangidwe ndi ntchito. Kugwiritsiridwa ntchito kwa nano ceria monga zokutira ndi zowonjezera kungapangitse kukana kwa okosijeni, kutentha kotentha, kutsekemera kwa madzi, ndi sulfurization katundu wa alloys kutentha kwambiri ndi zitsulo zosapanga dzimbiri, komanso angagwiritsidwe ntchito ngati inoculant kwa ductile iron.
Amagwiritsidwa ntchito pazinthu zina
Nano cerium oxide ali ndi ntchito zina zambiri, monga kugwiritsa ntchito ma cerium oxide based composite oxides monga ma electrolyte m'maselo amafuta, omwe amatha kukhala ndi kachulukidwe waposachedwa wa oxygen pakati pa 500 ℃ ndi 800 ℃; Kuwonjezera kwa cerium oxide panthawi ya vulcanization ya rabara kungakhale ndi kusintha kwina pa rabala; Cerium oxide imagwiranso ntchito yofunikira m'magawo monga zida zowunikira komanso maginito.
