Cov khoom siv lim dej diatomite tuaj yeem muab faib ua cov khoom algae qhuav, cov khoom calcined thiab cov khoom flux calcined raws li cov txheej txheem ntau lawm sib txawv.

① Cov khoom qhuav
Tom qab ntxuav, ziab ua ntej thiab zom, cov khoom siv raw yuav qhuav ntawm 600-800 ° C, thiab tom qab ntawd zom. Hom khoom no muaj cov khoom me me heev thiab tsim nyog rau kev lim dej kom raug. Nws feem ntau siv ua ke nrog lwm cov khoom siv lim dej. Cov khoom qhuav feem ntau yog daj daj, tab sis kuj dawb mis nyuj thiab xim grey daj.

② Cov khoom siv calcined
Cov diatomite uas tau ntxuav, qhuav thiab tsoo lawm raug pub rau hauv lub qhov cub rotary, calcined ntawm 800-1200 ° C, tom qab ntawd tsoo thiab muab qib kom tau txais cov khoom calcined. Piv nrog cov khoom qhuav, qhov permeability ntawm cov khoom calcined yog ntau dua peb zaug. Cov khoom calcined feem ntau yog xim liab dawb.

③ Cov khoom siv flux calcined
Tom qab ntxuav, ziab thiab sib tsoo, cov khoom siv raw ntawm diatomite yog ntxiv nrog me ntsis sodium carbonate, sodium chloride thiab lwm yam AIDS yaj, thiab calcined ntawm 900 ~ 1200 ° C. tom qab sib tsoo thiab qib me me, cov khoom flux calcined tau txais. Qhov permeability ntawm cov khoom flux calcined yog qhov pom tseeb nce, uas yog ntau dua 20 npaug ntawm cov khoom qhuav. Cov khoom flux calcined feem ntau yog dawb, thiab lub teeb liab thaum cov ntsiab lus ntawm Fe2O3 siab lossis qhov ntau ntawm flux yog me me.
