Mabda’a calcination foornada muffle

Calcination foornada suufka: daaweynta kulaylka hawada ama gaaska aan shaqayn ee heerkul gaar ah, oo loo yaqaan calcination ama dubay

Isbeddellada ugu waaweyn ee jireed iyo kiimikaad ee habka calcination foornada maaf waa:

(1) Daboolida kulaylka: ka saar biyaha kiimikaad ku xidhan, CO2, NOx iyo wasakhda kale ee kacsan. Heerkulka sare, oksaydhyadu waxay sidoo kale mari karaan falcelin adag si ay u sameeyaan xaalad isku dhafan oo firfircoon;

(2) Dib-u-crystalization: Qaab kaamiro ah oo gaar ah, cabbirka crystal, qaab dhismeedka daloolka iyo dusha gaarka ah ayaa la heli karaa;

(3) crystallites si sax ah ayaa loo miiray si loo hagaajiyo xoogga farsamada.

Qodobbada ugu muhiimsan ee saameeya geeddi-socodka calcination: heerkulka calcination, halabuurka wajiga gaaska, xasiloonida kulaylka ee xarunta, iwm. Sidaa darteed, marka loo eego xasilloonida kulaylka ee xeryahooda kala duwan (sida carbonate, oxide, hydroxide-sulfide, cusbada oxide, iwm. ), Heerkulka calcination-ka iyo isku-dhafka wajiga gaaska waa la xakameyn karaa si doorar loogu beddelo xasilloonida kulaylka ee xeryahooda qaarkood. Halabuurka ama qaabka crystal ayaa isbeddelaya, ka dibna lagu daaweeyaa habab u dhigma, waxay gaari karaan ujeedada ka saarista wasakhda iyo kala-soocidda iyo tayeynta kooxaha waxtarka leh.
