Zothandizira zosefera za Diatomite zitha kugawidwa m'magulu ouma algae, zinthu zopangidwa ndi calcium ndi zinthu zopangidwa ndi flux calcium malinga ndi njira zosiyanasiyana zopangira.

① Zouma
Pambuyo poyeretsa, kuumitsa ndi kuyeretsa, zinthu zopangira zimaumitsidwa pa 600-800 ° C, kenako zimachotsedwa. Mtundu uwu wa chinthu uli ndi tinthu tating'onoting'ono kwambiri ndipo ndi woyenera kusefedwa molondola. Nthawi zambiri umagwiritsidwa ntchito limodzi ndi zinthu zina zothandizira kusefera. Zinthu zouma nthawi zambiri zimakhala zachikasu chopepuka, komanso zoyera ngati mkaka komanso zotuwa pang'ono.

② Zinthu zopangidwa ndi calcium
Diatomite yoyeretsedwa, youma komanso yophwanyika imalowetsedwa mu uvuni wozungulira, ndikuyikidwa mu calcium pa 800-1200 ° C, kenako nkuphwanyika ndikuyikidwa mu grade kuti ipeze calcium. Poyerekeza ndi zinthu zouma, kuchuluka kwa calcium m'zinthu zomwe zili mu calcium kumaposa katatu. Zinthu zomwe zili mu calcium nthawi zambiri zimakhala zofiira pang'ono.

③ Zinthu zopangidwa ndi calcium
Pambuyo poyeretsa, kuumitsa ndi kupukuta, zinthu zopangira za diatomite zimawonjezedwa ndi sodium carbonate pang'ono, sodium chloride ndi AIDS ina yosungunuka, ndikusungunuka pa 900 ~ 1200 ° C. Pambuyo popukuta ndi kuyika kukula kwa tinthu, chinthu chopangidwa ndi flux calcined chimapezeka. Kulowa kwa chinthu chopangidwa ndi flux calcined kumawonjezeka, komwe kuli kopitilira nthawi 20 kuposa chinthu chouma. Zinthu zopangidwa ndi flux calcined nthawi zambiri zimakhala zoyera, komanso pinki yopepuka pamene kuchuluka kwa Fe2O3 kuli kokwera kapena kuchuluka kwa flux kuli kochepa.
