Zothandizira zosefera za Diatomite zitha kugawidwa m'magulu owuma a algae, zinthu zowerengeka komanso zinthu zowerengeka molingana ndi njira zosiyanasiyana zopangira.

① Zinthu zouma
Pambuyo pa kuyeretsedwa, kuyanika kusanachitike ndi kuyambiranso, zopangira zimawumitsidwa pa 600-800 ° C, kenako ndikusinthidwa.Mtundu uwu wa mankhwala ali abwino kwambiri tinthu kukula ndi oyenera kusefera mwatsatanetsatane.Nthawi zambiri amagwiritsidwa ntchito limodzi ndi zida zina zosefera.Zouma zouma nthawi zambiri zimakhala zachikasu, komanso zoyera zamkaka komanso zotuwa.

② Zogulitsa zamchere
Diatomite yoyeretsedwa, yowuma komanso yophwanyidwa imadyetsedwa mu uvuni wozungulira, wotenthedwa pa 800-1200 ° C, kenako ndikuphwanyidwa ndikusinthidwa kuti mupeze mankhwala owerengeka.Poyerekeza ndi mankhwala youma, permeability mankhwala calcined ndi kuposa katatu apamwamba.Zogulitsa zowerengeka nthawi zambiri zimakhala zofiira.

③ Flux calcined mankhwala
Pambuyo pa kuyeretsedwa, kuyanika ndi kupera, zopangira za diatomite zimawonjezedwa ndi sodium carbonate pang'ono, sodium kolorayidi ndi AIDS zina zosungunula, ndi calcined pa 900 ~ 1200 ° C. pambuyo pogaya ndi tinthu tating'onoting'ono, calcined mankhwala ndi flux calcined. analandira.The permeability wa flux calcined mankhwala mwachionekere chawonjezeka, amene nthawi zoposa 20 za mankhwala youma.Mankhwala opangidwa ndi flux calcined nthawi zambiri amakhala oyera, ndi pinki yowala pamene zomwe zili mu Fe2O3 ndizokwera kapena kuchuluka kwa flux kumakhala kochepa.
