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 Carbonate.

Astaamaha Muhiimka ah:

Nadiifnimo Sare:Cabbirka Walxaha Weyn ee Cerium Carbonate 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 Carbonate si degdeg ah ayuu ugu milmi karaa biyaha iyo asiidhyada xooggan.

Joogto ah: Maareynta dufcadda adag ee wax soo saarkaCabbirka Walxaha Weyn ee Cerium Carbonate waxay hubisaa tayada xasilloon ee wax soo saarka baaxadda weyn ee warshadaha.

Kaaliyaha warshadaha kiimikada: Kaaliyaha cerium-ka ee walxaha waaweyn waa walax horudhac ah oo muhiim u ah diyaarinta kaaliyaha saddex-geesoodka ah ee qiiqa baabuurta. Iyada oo loo marayo kalsiyum heerkulka sare, waxaa loo rogi karaa kaarboon oksaydh oo leh awood kaydin oksijiin oo sareysa, taasoo si wax ku ool ah u horumarinaysa falcelinta nadiifinta kaarboon oksaydh, hydrocarbons, iyo oksaydhyada nitrogen.

Wakiilka Ka Saarista Fosfooraska ee Waxtarka leh: Iyada oo lagu saleynayo isku xirnaanta sare ee u dhaxaysa ion-yada cerium iyo ion-yada fosfooraska, kaarbonat-ka cerium-ka ee walxaha waaweyn ayaa loo isticmaali karaa sidii wakiilka ka saarista fosfooraska si loogu daaweeyo biyaha iyo dib u soo celinta jirka biyaha eutrophic. Cabbirkeeda walxaha waaweyn wuxuu suurtogal ka dhigayaa waxqabadka ka saarista ee wanaagsan ee codsiyada wax ku oolka ah, isagoo fududeynaya kala-soocidda iyo soo kabashada, iyo si wax ku ool ah u yareynaya wadarta guud ee fiirsashada fosfooraska ee wasakhda ilaa heer aad u hooseeya (tusaale ahaan, laga bilaabo 0.55 mg-P/L ilaa≤0.03 mg-P/L).

Dhoobada iyo Qalabka Nadiifinta: Kaarboonat-ka weyn ee cerium-ka ah waa walax muhiim ah oo ceeriin ah oo loogu talagalay soo saarista dhoobada gaarka ah (sida dhoobada elektaroonigga ah) iyo budada dhalaalinta waxqabadka sare leh. Cabbirkeeda walxaha waaweyn wuxuu ka caawiyaa in la gaaro dusha sare ee dhalaalinta, taas oo muhiim u ah nadiifinta farsamada kiimikada (CMP) ee muraayadaha indhaha iyo wafer-ka semiconductor-ka. Waxa kale oo loo isticmaali karaa in lagu daro walxaha adag si loo xoojiyo waxqabadka maaddada.

Isku-darka Kiimikada Dhexdhexaadinta: Iyada oo ah horudhac muhiim u ah isku-dhafka cerium, cerium carbonate-ka weyn ee la isku-darka ah ayaa loo isticmaalaa in lagu sameeyo cusbo cerium kala duwan (sida cerium nitrate, cerium chloride, iwm.) iyo ugu dambeyntii si loo diyaariyo cerium oxide saafi ah oo sarreeya. Iyadoo si adag loo xakameynayo xaaladaha roobka (sida uruurinta xalka dhulka naadirka ah, heerkulka falcelinta, iyo waqtiga gabowga), cabbirka walxaha ee badeecada si xakameysan ayaa loo hagaajin karaa (cabbirka walxaha dhexe ee D50 wuxuu gaari karaa qiyaastii 150μm), oo buuxinaya shuruudaha gaarka ah ee codsiyada kala duwan ee hoos yimaada ee cabbirka walxaha ceeriin ah.
