Cov neeg muas zaub tau yuav tus neeg sawv cev kho dej kev sib tham, tuaj yeem ncaj qha mus rau hauv cov dej phwj tuaj? Tsis tau, ib txhia kuj nug qhov chaw dej phwj dissolving dej los kho cov khoom?tuaj yeem txo cov dej phwj tuaj, tab sis kuj tuaj yeem siv cov dej phwj tuaj, uas tsis tuaj yeem ua tau, cov dej kho dej flocculants yog mesh lossis saw qauv, cov qauv no yuav tsum tau ua kom tiav tom qab kev sib cais kom ua lub luag haujlwm ntawm kev kho dej phwj tuaj.
Tus neeg saib xyuas dej feem ntau yog hais txog polyacrylamide qhuav hmoov los yog polyacrylamide emulsion feem ntau tsis ncaj qha ntxiv rau kev siv, nws yuav tsum tau yaj tom qab dilution, kev siv cov yaj dilution zoo dej.Ib qho kev zam tuaj yeem ua tau yog tias cov hmoov qhuav polyacrylamide ncaj qha siv los ua cov khoom siv raw lossis cov qauv sib xyaw nrog lwm cov ntaub ntawv raw.Yog li dab tsi koj dilute polyacrylamide nrog?Qee qhov chaw rau ntau qhov laj thawj, tuaj yeem siv purified "s dej phwj" los yog cov dej ntws mus rau yaj, feem ntau tsis pom zoo kom ua li ntawd, ntau tom qab kev kho dej, yuav muaj impurities, thiab polyacrylamide tsis haum rau cov kua qaub, alkaline thiab lwm yam dej kom yaj.Qhov kev xav tau niaj hnub yog dilute cov dej kho tus neeg saib xyuas polyacrylamide nrog dej huv.
Vim li cas thiaj yuav tsum tau siv tshuaj kho dej kom qhuav hmoov kom yaj thiab diluted?
Qee cov neeg siv yuav xav tias vim li cas nws tsis tuaj yeem ntxivpolyacrylamidehmoov ncaj qha mus rau cov dej phwj tuaj uas yuav tsum tau kho.Qhov no yog vim tus neeg saib xyuas dej yuav tsum tau ntxiv dej los npaj ib qho kev daws teeb meem, nws lub sij hawm tawg kuj siv li 40-60 feeb.Nws yuav tsis ua haujlwm yog tias koj ntxiv nws ncaj qha.Dej kho tus neeg sawv cev emulsion yog kua, kuj xav kom dilute?Yog lawm, vim hais tias feem ntau cov khoom emulsion no, cov ntsiab lus tseem ceeb yog qhov siab, feem ntau yog li 30-45%, xws li cov concentration siab tsis haum rau kev siv ncaj qha, kev siv dav dav yog raws li qhov concentration ntawm 0.1-0.5% tshuaj npaj diluent. , kev kho dej flocculant yog lub network lossis cov qauv saw, Cov qauv no yuav tsum tau yaj thiab txuas ntxiv mus ua lub luag haujlwm hauv kev kho cov dej phwj tuaj.
