Yintoni i-cerium oxide? Ziziphi izinto ezisetyenziswayo?

I-Cerium oxide, kwaziwa njengei-cerium dioxide, inefomula yemolekyuliCeO2. Ingasetyenziswa njengezinto zokupholisha, ii-catalysts, i-UV absorbers, i-electrolyte yeeseli ze-fuel, i-absorberi yokukhupha iimoto, iiseramikhi zombane, njl.

Usetyenziso lwamva nje ngo-2022: Iinjineli ze-MIT zisebenzisa ii-ceramics ukwenza iiseli zamafutha eglucose ukunika amandla izixhobo ezifakelwe emzimbeni. I-electrolyte yale glucose fuel cell yenziwe ngecerium dioxide, ene-ion conductivity ephezulu kunye namandla omatshini kwaye isetyenziswa ngokubanzi njenge-electrolyte yeeseli ze-hydrogen fuel. I-cerium dioxide nayo ibonakaliswe ukuba i-biocompatible

Ukongeza, uluntu lophando lomhlaza lufunda ngenkuthalo i-cerium dioxide, efana ne-zirconia esetyenziselwa ukufakelwa kwamazinyo kwaye ine-biocompatibility kunye nokhuseleko.

·Isiphumo sokugudisa umhlaba esinqabileyo

Umgubo wokugudisa umhlaba onqabileyo uneengenelo zesantya sokupholisha ngokukhawuleza, ukuguda okuphezulu, kunye nobomi benkonzo ende. Xa kuthelekiswa nepolishi yendabuko - umgubo obomvu wentsimbi, ayingcolisi indalo kwaye kulula ukuyisusa kwinto ebambelelayo. Ukupholisha i-lens nge-cerium oxide polishing powder kuthatha umzuzu omnye ukugqiba, ngelixa usebenzisa i-iron oxide polishing powder kuthatha imizuzu engama-30-60. Ke ngoko, umgubo onqabileyo wokupolisha umhlaba unezibonelelo zedosi ephantsi, isantya sokupholisha ngokukhawuleza, kunye nempumelelo ephezulu yokupolisha. Kwaye inokutshintsha umgangatho wokupolisha kunye nendawo yokusebenza.

Kucetyiswa ukusebenzisa i-cerium polishing powder ephezulu kwiilensi zamehlo, njl. Umgubo wokupolisha wecerium ophantsi usetyenziswa ngokubanzi ukupolisha iglasi yeglasi ecaba, iglasi yetyhubhu yemifanekiso, iiglasi, njl.

·Ukufaka isicelo kwii-catalysts

I-Cerium diokside ayinayo kuphela indawo yokugcina i-oksijini kunye nemisebenzi yokukhulula, kodwa ikwayeyona nto isebenzayo i-oxide catalyst kuthotho lwe-oxide yomhlaba enqabileyo. Ii-Electrodes zidlala indima ebalulekileyo kwii-electrochemical reactions of fuel cells. I-Electrodes ayiyona nje into efunekayo kwaye ibalulekileyo kwiiseli ze-fuel, kodwa zikwasebenza njenge-catalysts ye-electrochemical reaction. Ngoko ke, kwiimeko ezininzi, i-cerium dioxide ingasetyenziselwa njengesongezo sokuphucula ukusebenza kwe-catalyst ye-catalyst.

·Isetyenziselwa iimveliso zokufunxa iUV

Kwizinto zokuthambisa ezikumgangatho ophezulu, i-nano CeO2 kunye ne-SiO2 i-surface coated composites isetyenziswa njengezona zixhobo zokufunxa i-UV ukoyisa imiqobo ye-TiO2 okanye i-ZnO enombala ophaphathekileyo kunye nesantya esisezantsi sokufunxa kwe-UV.

Ukongeza ekusetyenzisweni kwizinto zokuthambisa, i-nano CeO2 inokongezwa kwiipolymers ukulungiselela iintsinga ze-UV ezinganyangekiyo zokuguga, ezikhokelela kumalaphu e-chemical fiber ane-UV egqwesileyo kunye namazinga okukhusela kwimitha ye-thermal. Ukusebenza kuphezulu kune-TiO2 esetyenziswayo ngoku, i-ZnO, kunye ne-SiO2. Ukongeza, i-nano CeO2 inokongezwa kwiingubo ukuxhathisa imitha ye-ultraviolet kunye nokunciphisa ukuguga kunye nesantya sokuthotywa kweepolymers.
