Diatomite Filter Aid yog dab tsi?

Diatomite Filter Aid yog dab tsi?

Cov khoom siv lim dej diatomite muaj cov qauv microporous zoo, kev ua haujlwm adsorption, thiab kev ua haujlwm tiv thaiv kev nias. Lawv tsis tsuas yog ua tiav qhov sib piv zoo rau cov kua dej lim, tab sis kuj lim cov khoom me me uas raug tshem tawm, ua kom pom tseeb. Lub ntiaj teb diatomaceous yog cov av nkos ntawm cov seem diatom ib lub cell qub. Nws cov yam ntxwv suav nrog lub teeb yuag, porosity, lub zog siab, hnav tsis kam, rwb thaiv tsev, rwb thaiv tsev thermal, adsorption, thiab sau, ntawm lwm yam khoom zoo heev.

Lub ntiaj teb diatomaceous yog cov av nplaum ntawm cov seem diatom qub uas muaj ib lub hlwb xwb. Nws cov yam ntxwv suav nrog lub teeb yuag, porosity, muaj zog heev, tiv taus kev hnav, rwb thaiv tsev, rwb thaiv tsev thermal, adsorption, thiab filling, ntawm lwm yam zoo heev. Muaj kev ruaj khov tshuaj lom neeg zoo. Nws yog ib qho khoom siv tseem ceeb rau kev lag luam rwb thaiv tsev, sib tsoo, lim dej, adsorption, anticoagulation, demolding, filling, thiab carrier. Nws tuaj yeem siv dav hauv kev lag luam xws li metallurgy, kev lag luam tshuaj lom neeg, hluav taws xob, kev ua liaj ua teb, chiv, cov ntaub ntawv tsim kho thiab cov khoom rwb thaiv tsev. Nws kuj tseem siv tau ua cov khoom siv rau kev lag luam rau yas, roj hmab, ceramics, papermaking, thiab lwm yam lag luam.

Kev faib tawm

Diatomite Filter Aid yog muab faib ua cov khoom qhuav, cov khoom calcined, thiab cov khoom flux calcined raws li cov txheej txheem ntau lawm sib txawv.

①Cov khoom qhuav

Qhuav cov khoom siv av qhuav uas tau lim, ua ntej ziab, thiab tsoo silica qhuav ntawm qhov kub ntawm 600-800 ° C, thiab tom qab ntawd zom lawv ua hmoov. Cov khoom no muaj qhov loj 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 muaj xim dawb thiab xim grey daj.

②Cov khoom siv calcined

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

③Cov khoom siv flux calcined

Tom qab ntxuav, ziab, thiab zom, cov khoom siv diatomaceous earth raw khoom ntxiv nrog me me ntawm cov tshuaj fluxing xws li sodium carbonate thiab sodium chloride, thiab calcined ntawm qhov kub ntawm 900-1200 ° C. Tom qab zom thiab ntsuas qhov loj me ntawm cov khoom me me, cov khoom flux calcined tau txais. Qhov permeability ntawm cov khoom flux calcined tau nce ntxiv ntau, ntau dua 20 npaug ntawm cov khoom qhuav. Cov khoom calcined nrog flux feem ntau yog xim dawb, thiab thaum Fe2O3 cov ntsiab lus siab lossis cov tshuaj flux tsawg, lawv zoo li xim liab dawb.
