Kuv yuav xaiv hom polyacrylamide li cas?

Polyacrylamide(Pam) feem ntau tuaj yeem raug faib rau anionic, cationic, thiab kev nonionic raws li Ion hom. Nws yog tsuas yog siv rau flocculation hauv kev kho dej. Thaum xaiv, ntau hom dej lwg yuav xaiv ntau hom. Koj yuav tsum xaiv cov ncej zoo raws li cov yam ntxwv ntawm koj cov dej phwj. Nyob rau tib lub sijhawm, koj yuav tsum tau hais meej hauv cov txheej txheem ntawm polyacrylamide yuav raug ntxiv thiab lub hom phiaj koj xav ua kom tiav los ntawm kev siv nws.

Cov cuab yeej qhia txuj ci polyacrylamide feem ntau suav nrog kev ua haujlwm hnyav, kev ua kom pom tseeb, thiab lwm yam cov ntsuas no yuav tsum tau qhia meej raws li cov dej khib nyiab koj tab tom kho.

1. Molecular hnyav / viscosity

Polyacrylamide muaj ntau yam ntawm cov tes hnyav, los ntawm qhov qis rau qhov siab heev. Molecular qhov hnyav cuam tshuam rau kev ua yeeb yam ntawm cov polymers hauv cov ntawv thov sib txawv. Siab molecular phaus polyacrylamide feem ntau yog siv tau zoo dua hauv cov txheej txheem flocculation vim tias lawv cov polymer ntev dua thiab tuaj yeem sib txuas ntau dua ua ke.

Lub viscosity ntawm PAM kev daws teeb meem yog ntau heev. Thaum lub ionization yog qhov ruaj khov, qhov loj dua cov molecular qhov hnyav ntawm polyacrylamide, ntau dua cov viscosity ntawm nws cov kev daws teeb meem. Qhov no yog vim tias cov macromolecular chart ntawm polyacrylamide yog ntev thiab nyias, thiab cov tsis kam mus rau kev txav hauv cov tshuaj yog qhov loj heev.

2. Qib ntawm hydrolysis thiab ionicity

Lub ionicity ntawm Pam muaj qhov cuam tshuam zoo rau nws siv cov nyhuv yog nyob ntawm hom thiab xwm txheej ntawm cov khoom siv tau zoo hauv cov xwm txheej sib txawv. Thaum lub iionic lub zog ntawm cov khoom kho yog siab (ntau inorganic teeb meem), ionicity cov pam siv yuav tsum muaj siab dua, txwv tsis pub nws yuav tsum qis dua. Feem ntau, cov qib ntawm kev npau suav yog hu ua cov degree ntawm hydrolysis, thiab qib degree yog feem ntau hu ua kev kawm tiav.

Yuav Ua Li Cas Xaiv PolyacrylamideNyob ntawm cov concentration ntawm colloids thiab tshem tawm cov dej hauv dej. Tom qab nkag siab cov ntsuas saum toj saud, yuav ua li cas xaiv cov pa Pam haum?

1. Nkag siab lub hauv paus ntawm cov dej phwj tuaj

Ua ntej, peb yuav tsum nkag siab qhov chaw, xwm txheej, muaj pes tsawg leeg, thiab lwm yam ntawm cov sludge.

Feem ntau hais lus, cationic polyacrylamide yog siv los kho cov organic sludge, thiab anionic polyacrylamide yog siv los kho inorganic sludge. Thaum PH yog siab, cationic polyacrylamide yuav tsum tsis txhob siv, thiab thaum twg, anionic polyacrylamide yuav tsum tsis txhob siv. Muaj zog acidity ua rau nws tsis zoo los siv anionic polyacrylamide. Thaum cov khoom siv ruaj khov ntawm sludge yog siab, tus nqi ntawm polyacrylamide siv yog loj.

2. Xaiv Oionicity

Rau sludge uas yuav tsum muaj lub cev qhuav dej hauv cov ionicculanity, uas koj tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws los xaiv cov txiaj ntsig zoo tshaj plaws thiab txo cov nqi, txuag nqi.

3. Xaiv cov molecular hnyav

Feem ntau hais lus, siab dua cov roj ntsha hnyav ntawm polyacrylamide cov khoom, ntau dua cov viscosity, tab sis siv, qhov siab dua molecular hnyav ntawm cov khoom lag luam, qhov zoo dua cov khoom siv siv. Hauv kev siv tshwj xeeb, tsim nyog molecular hnyav ntawm polyacrylamide yuav tsum tau txiav txim siab raws li kev lag luam kev lag luam tiag tiag, dej ua khoom zoo thiab kho cov khoom siv.

Thaum koj yuav thiab siv Pam thawj zaug, nws raug nquahu kom muab cov xwm txheej tshwj xeeb rau cov chaw tsim khoom hauv flocculant, thiab peb yuav pom zoo cov khoom lag luam uas tsim nyog dua rau koj. Thiab xa cov qauv rau kev sim. Yog tias koj muaj kev paub ntau hauv koj cov dej phwj tuaj, koj tuaj yeem qhia peb koj cov kev xav tau, thiab muab peb cov txheej txheem ua ntej, lossis peb yuav phim koj nrog txoj cai polyacrylamide.
