Diatomite Filter Aid yog dab tsi?

Diatomite Filter Aid muaj cov qauv zoo microporous, kev ua haujlwm adsorption, thiab kev ua haujlwm los tiv thaiv compression. Lawv tuaj yeem ua tsis tau tsuas yog ua tau zoo txaus tus nqi piv rau cov kua lim, tab sis kuj lim tawm cov khib nyiab zoo, ua kom pom tseeb. Lub ntiaj teb diatomaceous yog ib qho av ntawm ib leeg-cell diatom seem. Nws cov yam ntxwv muaj xws li lub teeb yuag, porosity, siab zog, hnav tsis kam, rwb thaiv tsev, thermal 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, tshuaj lom neeg kev lag luam, hluav taws xob fais fab, 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.

Kev faib tawm

Diatomite Filter Aidare muab faib ua cov khoom qhuav, calcined khoom, thiab flux calcined khoom raws li cov txheej txheem ntau lawm.

①Cov khoom qhuav

Qhuav lub purified, pre qhuav, thiab crushed silica qhuav av raw cov ntaub ntawv ntawm ib tug kub ntawm 600-800 ° C, thiab ces grind lawv mus rau hauv hmoov. 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.

②Calcined khoom

Cov purified, qhuav, thiab crushed diatomaceous ntiaj teb raw cov ntaub ntawv 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 rau cov khoom qhuav, calcined cov khoom muaj permeability siab dua peb zaug. Cov khoom calcined feem ntau yog xim liab.

③Flux calcined khoom

Tom qab purification, ziab, thiab crushing, diatomaceous lub 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. Qhov permeability ntawm cov khoom flux calcined tau nce ntxiv, 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 los yog cov tshuaj flux tsawg, lawv tshwm liab liab.
