Diatomaceous earth filter aids muaj cov qauv zoo microporous, adsorption kev ua tau zoo, thiab compressive tsis kam, uas tsis tsuas yog ua kom cov kua lim dej kom ua tiav qhov zoo txaus tus nqi, tab sis kuj lim tawm cov khib nyiab zoo, ua kom pom tseeb.Lub ntiaj teb diatomaceous yog ib tug sediment ntawm ancient ib leeg-celled diatom seem.Nws cov yam ntxwv muaj xws li lub teeb yuag, ntxeem tau, siab zog, hnav-tiv taus, rwb thaiv tsev, rwb thaiv tsev, adsorption, thiab filling, thiab lwm yam khoom zoo heev.

Lub ntiaj teb diatomaceous yog ib tug sediment ntawm ancient ib leeg-celled diatom seem.Nws cov yam ntxwv muaj xws li lub teeb yuag, ntxeem tau, siab zog, hnav-tiv taus, rwb thaiv tsev, rwb thaiv tsev, adsorption, thiab filling, thiab lwm yam khoom zoo heev.Muaj tshuaj lom neeg ruaj khov zoo.Nws yog ib qho tseem ceeb ntawm cov khoom siv rau rwb thaiv tsev, sib tsoo, pom, adsorption, anticoagulation, demolding, filling, thiab carrier.Nws tuaj yeem siv dav hauv kev lag luam xws li metallurgy, chemical engineering, hluav taws xob, kev ua liaj ua teb, chiv, khoom siv hauv tsev thiab cov khoom siv rwb thaiv tsev.Nws tseem tuaj yeem siv los ua cov khoom siv ua haujlwm rau cov yas, roj hmab, ceramics, papermaking, thiab lwm yam lag luam.

Diatomaceous earth filter aids muab faib ua cov khoom qhuav, calcined khoom, thiab flux calcined khoom raws li cov txheej txheem ntau lawm.
① Cov khoom qhuav
Cov purified, pre qhuav, thiab crushed silica qhuav av raw khoom yog qhuav ntawm ib tug kub ntawm 600-800 ° C thiab ces crushed.Cov khoom no muaj ib tug zoo particle loj thiab yog haum rau precision pom.Nws yog feem ntau siv ua ke nrog lwm cov lim pab.Cov khoom qhuav yog feem ntau lub teeb daj, tab sis kuj muaj mis nyuj dawb thiab lub teeb grey.

② Calcined khoom
Cov purified, qhuav, thiab crushed diatomaceous ntiaj teb raw khoom yog pub rau hauv ib tug teb kiln, calcined ntawm ib tug kub ntawm 800-1200 ° C, thiab ces crushed thiab graded kom tau cov khoom calcined.Piv nrog rau cov khoom qhuav, qhov permeability ntawm cov khoom calcined yog ntau tshaj peb zaug siab dua.Cov khoom calcined feem ntau yog xim liab.

③ Flux calcined khoom
Tom qab purification, ziab, thiab crushing, diatomaceous ntiaj teb raw khoom yog ntxiv nrog ib tug me me ntawm fluxing tshuaj xws li sodium carbonate thiab sodium chloride, thiab calcined ntawm ib tug kub ntawm 900-1200 ° C. Tom qab crushing thiab particle loj grading, lub flux calcined khoom tau txais.Lub permeability ntawm flux calcined cov khoom tau nce zuj zus, uas yog ntau tshaj 20 npaug ntawm cov khoom qhuav.Cov khoom calcined ntawm flux feem ntau yog dawb, thiab thaum Fe2O3 cov ntsiab lus siab los yog cov tshuaj flux tsawg, lawv tshwm liab liab.

Lub ntsiab drawbacks ntawm diatomaceous ntiaj teb lim pab yog:

1. Tsis muaj peev txheej.Kev tsim cov diatomaceous lub ntiaj teb lim kev pab yuav tsum tau zoo diatomaceous lub ntiaj teb nrog siab diatom ntsiab lus.Txawm hais tias Tuam Tshoj muaj ntau cov peev txheej hauv ntiaj teb diatomaceous, feem coob yog nruab nrab mus rau qib qis diatomaceous lub ntiaj teb mines, uas nyuaj ua kom tau raws li qhov yuav tsum tau ua;

2. Tus nqi tsim khoom yog qhov siab.Cov txheej txheem ntau lawm ntawm diatomaceous lub ntiaj teb yog qhov nyuaj, thiab ua ke nrog tus nqi siab ntawm cov khoom siv zoo diatomaceous lub ntiaj teb, cov nqi tsim khoom ntawm diatomaceous lub ntiaj teb lim pab hauv Suav teb tau khaws cia ntawm qib siab;

3. Qhov pom tus nqi kuj qeeb thiab qhov ntom ntom ntom ntom ntom ntom.Ntxiv ntau raws li nws qhov zoo feem ntau tsis ua raws li qhov xav tau, thiab ntxiv ntau ntxiv yuav ua rau tus nqi nce ntxiv.Qee tus neeg xav tsim cov khoom lag luam diatomaceous lub ntiaj teb uas tsis tshua muaj qhov ntom ntom, tab sis vim muaj kev txwv ntawm cov khoom siv thiab cov qauv ntawm cov khoom siv raw, cov txiaj ntsig txaus siab tsis tau ua tiav txog tam sim no;

4. Cov tshuaj lom neeg ruaj khov tsis zoo tagnrho.Cov ntsiab lus ntawm cov khoom tsis zoo xws li hlau thiab calcium hauv lub ntiaj teb diatomaceous yog qhov siab thiab muaj nyob rau hauv ib lub xeev sib cais, yog li nws qhov kev sib cais yog siab.Thaum lim ntau cov dej haus thiab cov dej haus cawv, cov hlau tawg siab tuaj yeem cuam tshuam qhov saj thiab tsw ntawm cov khoom.
