Qalabka shaandhada Diatomite waxaa loo qaybin karaa alaabada algae qalalan, alaabada calcined iyo alaabada calcined flux iyadoo loo eegayo hababka wax soo saarka ee kala duwan.

① Alaabada la qalajiyey
Ka dib marka la nadiifiyo, la qalajiyo ka hor iyo ka dib, walxaha ceeriin ah waxaa lagu qalajiyaa heerkul ah 600-800 ° C, ka dibna waa la shiiday. Noocan badeecada ah wuxuu leeyahay cabbir aad u fiican oo ku habboon shaandhaynta saxda ah. Badanaa waxaa loo isticmaalaa iyadoo lala kaashanayo qalabka kale ee shaandhada. Badeecadaha qalalan badanaa waa huruud khafiif ah, laakiin sidoo kale waa caddaan caano ah iyo cawl khafiif ah.

② Badeecooyinka Calcined
Diatomite-ka la nadiifiyey, la qalajiyey oo la jajabiyey ayaa lagu shubaa foorno wareeg ah, oo lagu shubay heerkul ah 800-1200 ° C, ka dibna la burburiyey oo la kala saaray si loo helo badeecada la qalajiyey. Marka la barbardhigo alaabada qalalan, marin u helidda alaabada la qalajiyey ayaa ka badan saddex jeer ka badan. Badeecadaha la qalajiyey ayaa inta badan casaan khafiif ah leh.

③ Badeecooyinka lagu dahaadhay dareeraha
Ka dib marka la nadiifiyo, la qalajiyo oo la shiido, walxaha cayriin ee diatomite waxaa lagu daraa xaddi yar oo sodium carbonate ah, sodium chloride iyo AIDS kale oo dhalaalaysa, waxaana lagu shubaa heerkul ah 900 ~ 1200 ° C. ka dib marka la shiido oo la kala saaro cabbirka walxaha, badeecada lagu shubo flux ayaa la helaa. Si cad ayaa loo kordhiyaa permeability-ka badeecada lagu shubo flux, taas oo ka badan 20 jeer tan badeecada qalalan. Badeecadaha lagu shubo flux waa cadaan, iyo casaan khafiif ah marka ay ku jirto Fe2O3 ay sarreyso ama xaddiga flux uu yar yahay.
