Diatomite lim pabmuaj cov qauv zoo microporous, kev ua haujlwm adsorption thiab kev ua haujlwm ntawm kev sib txhuam, uas tsis yog tsuas yog ua kom cov kua lim dej kom tau txais qhov sib piv zoo dua, tab sis kuj lim tawm cov khib nyiab zoo kom pom tseeb. Lub ntiaj teb diatomaceous yog qhov tso nyiaj ntawm qhov seem ntawm ib leeg-celled diatoms thaum ub. Nws cov yam ntxwv: lub teeb yuag, ntxeem tau, siab zog, hnav tsis kam, rwb thaiv tsev, rwb thaiv tsev kub, adsorption thiab filling thiab lwm yam kev ua tau zoo heev. Niaj hnub no, Junlian diatomite yuav nrov several txawv filtration txoj kev ntawm diatomite lim pab.

Lub diatomite lim pab tsuas yog ntxiab cov khoom impurity uas raug tshem tawm hauv cov kua ntawm qhov nruab nrab thiab cov channel los ntawm peb txoj haujlwm ntawm kev tshuaj xyuas, qhov tob tob, thiab adsorption, thiaj li ua tiav lub hom phiaj ntawm cov kua dej sib cais.

1. Diatomite tshuaj ntsuam nyhuv: Qhov no yog cov nyhuv lim dej. Thaum cov kua ntws los ntawm lub ntiaj teb diatomaceous, qhov pores ntawm lub ntiaj teb diatomaceous yog me dua li qhov me me ntawm cov impurity hais, kom cov impurity hais tsis tuaj yeem hla thiab cuam tshuam. Cov nyhuv yog hu ua kev tshuaj ntsuam xyuas.

2. Diatomite qhov tob nyhuv: Cov nyhuv tob yog qhov tuav cov nyhuv ntawm kev sib sib zog nqus pom. Hauv kev sib sib zog nqus pom, cov txheej txheem sib cais tsuas yog tshwm sim hauv "sab hauv" ntawm qhov nruab nrab. Ib feem ntawm cov impurity me me uas nkag mus rau saum npoo ntawm lub ncuav mog qab zib yog npog los ntawm diatomite. Sab hauv tortuous microporous qauv thiab cov pores finer nyob rau hauv lub lim ncuav mog qab zib yog thaiv. Xws li hais feem ntau me dua li cov micropores ntawm lub ntiaj teb diatomaceous. Thaum cov khoom tsoo cov phab ntsa ntawm cov channel, lawv tuaj yeem tso cov kua dej tawm. Txawm li cas los xij, seb nws tuaj yeem ua tiav qhov no yog nyob ntawm qhov sib npaug ntawm inertial quab yuam thiab tsis kam ntawm cov khoom. Qhov kev cuam tshuam thiab kev tshuaj ntsuam no zoo ib yam, thiab ob qho tib si muaj kev cuam tshuam rau cov neeg kho tshuab. Lub peev xwm los lim tawm cov khoom siv yog qhov tseem ceeb tsuas yog cuam tshuam nrog qhov sib txheeb loj thiab cov duab ntawm cov khoom thiab qhov pores.

3. Diatomite adsorption: Lub adsorption tuaj yeem suav tias yog electrokinetic attraction, uas feem ntau yog nyob ntawm cov khoom ntawm cov khoom thiab cov diatomite nws tus kheej. Lub ntsiab lus txoj hauj lwm ntawm lub ntiaj teb diatomaceous yog qhov tsis zoo, tus nqi tseeb yog qhov loj, thiab nws tuaj yeem nqus tau cov nqi zoo. Thaum cov khoom me dua li cov pores sab hauv ntawm lub ntiaj teb diatomaceous sib tsoo rau ntawm qhov chaw sab hauv ntawm lub ntiaj teb ntxeem tau diatomaceous, lawv tau nyiam los ntawm cov nqi hluav taws xob. Kuj tseem muaj hom kev sib koom ua ke ntawm cov khoom los tsim cov pawg thiab ua raws li lub ntiaj teb diatomaceous. Ob leeg koom nrog adsorption, thiab adsorption yog qhov nyuaj dua li ob qhov teebmeem dhau los. Nws yog feem ntau ntseeg tias yog vim li cas vim li cas cov khoom me me tshaj qhov pore txoj kab uas hla yog daig yog vim li cas: intermolecular rog (tseem hu ua van der Waals attraction), nrog rau cov dipole mus tas li, induced dipole, instant dipole thiab muaj peev xwm Ion pauv txheej txheem.
