Sharaxaadda & Astaamaha

Sharaxaad: WNX waxay isticmaashaa tiknoolajiyad wax soo saar oo otomaatig ah oo horumarsan waxayna isticmaashaa agab ceeriin oo tayo sare leh si ay u soo saarto tayo sare lehCabbirka Walxaha Weyn ee Cerium Oxide.

Astaamaha Muhiimka ah:

Nadiifnimo Sare:Cabbirka Walxaha Weyn ee Cerium Oxide

ma jiraan wax wasakh ah oo ka yimaada walxaha dhulka naadirka ah (sida birta, kalsiyum, soodhiyam), wasakhduna way yar tahay.

Milmida Wanaagsan:Cabbirka Walxaha Weyn ee Cerium Oxide

si degdeg ah ayuu ugu milmi karaa biyaha iyo asiidhyada xooggan.

Joogto ah: Maareynta dufcadda adag ee wax soo saarkaCabbirka Walxaha Weyn ee Cerium Oxide

waxay hubisaa tayada xasilloon ee wax soo saarka baaxadda weyn ee warshadaha.

Kaaliyeyaasha warshadaha kiimikada:Cabbirka Walxaha Weyn ee Cerium Oxide, sababtoo ah awooddeeda farsamo iyo xasilloonideeda sare, waxaa loo isticmaalaa sidii side kiciye aad u fiican oo ku jira fal-galayaasha sariiraha go'an ee u baahan inay u adkaystaan cadaadiska sare ama saameynta socodka hawada ee xawaaraha sare leh. Waxay si wax ku ool ah u qaadi kartaa biraha qaaliga ah (sida platinum iyo palladium) waxaana loo isticmaalaa hababka sida hydrogenation ee kiimikada batroolka, taasoo si weyn u kordhinaysa cimriga adeegga ee kiciyeyaasha. Astaamaha cilladaha bannaan ee oksijiinta ee gaarka ah ayaa sidoo kale ka dhigaya inay door muhiim ah ka ciyaarto nadiifinta qiiqa baabuurta (beddelayaasha kiciyaha saddex-geesoodka ah), kor u qaadista beddelka kaarboon monoksaydh (CO), hydrocarbons (HC), iyo nitrogen oxides (NOx).

Wakiilka Ka Saarista Fosfooraska Barkadda: TheCabbirka Walxaha Weyn ee Cerium Oxide Walxaha si wax ku ool ah ayay u nuugi karaan oo u soo saari karaan ion-yada fosfate-ka ee ku jira jirka biyaha, taasoo joojinaysa koritaanka algae iyo xallinta dhibaatada eutrophication-ka jirka biyaha. Cabbirka walaxda waa mid aad u weyn, waxqabadkeedana wuu ka wanaagsan yahay codsiyada dhabta ah ee jirka biyaha, taasoo sahlaysa soo kabashada dambe iyo yaraynta khatarta wasakhowga labaad.

Baytariyada iyo Qalabka Tamarta: Unugyada shidaalka ee oksaydhka adag (SOFCs),Cabbirka Walxaha Weyn ee Cerium Oxide waxaa loo isticmaali karaa sidii walxo elektrolayt ah. Xasilloonida xadka sare ee badarka waxay gacan ka geysataa kor u qaadida socodka ionic iyo cimri dhererka hawlgalka muddada dheer ee batteriga. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa sidii walxo ceeriin ah oo loogu talagalay diyaarinta walxaha kaydinta haydarojiinta ee elektrolaytka taban ee baytariyada nikkel-hydrogen, ama wax ka beddelka agabka elektroodka baytariga lithium-ion, taasoo hagaajinaysa waxqabadka wareegga ee baytariga iyada oo loo marayo qaab-dhismeedkiisa deggan.

Dhexdhexaadinta isku-darka kiimikada:Cabbirka Walxaha Weyn ee Cerium Oxide waa walax horudhac ah oo muhiim u ah isku-darka agabka kale ee ku salaysan cerium (sida cusbada cerium, oksaydhka cerium ee la dahaadhay, iwm.). Iyada oo loo marayo habaynta kiimikada oo dheeraad ah, waxaa loo beddeli karaa isku-dhisyo cerium ah oo leh qaab-dhismeedyo iyo sifooyin gaar ah, kuwaas oo loo isticmaalo meelaha sida dhoobada elektaroonigga ah iyo walxaha nuugista ultraviolet-ka.
