Polyacrylamideplays lub luag haujlwm tseem ceeb hauv kev kho dej, suav nrog kev lag luam dej, dej haus, dej phwj hauv nroog, sludge dewatering, thiab lwm yam. Tom qab ntawd dab tsi yog qhov zoo ntawm PAM tshuaj rau kev kho dej? Hauv tsab xov xwm no, peb yuav tham txog qhov teeb meem no.
Koj tuaj yeem xa mus rau tsab xov xwm dhau los:Dab tsi yog Polyacrylamide siv rau hauv kev kho dej?
Nyob rau hauv xyoo tas los no, raws li cov tshuaj kho dej tseem ceeb, polyacrylamide (PAM) tau siv dav hauv kev kho dej. Nws yog qhov tseeb vim nws cov khoom tshwj xeeb thiab kev ua tau zoo heev uas PAM ua lub luag haujlwm tseem ceeb hauv kev kho dej.
Qhov zoo ntawm PAM
Txhim kho dej zoo
PAM yog dav siv los ua dej flocculant. Thiab PAM flocculant tuaj yeem tshem tawm cov khib nyiab pov tseg, cov teeb meem organic, hnyav hlau ions thiab lwm yam teeb meem hauv dej los ntawm hluav taws xob neutralization.
Hauv kev lim dej haus, nws tuaj yeem txo qhov turbidity thiab hardness ntawm dej, yog li txhim kho cov dej zoo.
Rau kev kho dej khib nyiab, coagulation thiab flocculation hauv kev kho dej ntawm PAM tuaj yeem ua kom huv dej ntxiv thiab txo cov pa phem ib puag ncig.
Txo kev siv tshuaj
Vim muaj kev ua haujlwm siab ntawm PAM, nws yog ib qho kev hloov pauv rau qee cov tshuaj flocculants, xws li polyaluminum chloride, aluminium sulfate, thiab lwm yam. Qhov no tsis yog tsuas yog txo cov tshuaj noj, tab sis kuj txo cov nqi pov tseg.
Hauv kev siv cov tswv yim, kev siv PAM feem ntau tuaj yeem txo cov nqi ntawm lwm cov neeg ua hauj lwm raws li qhov ua tiav ntawm kev ua tiav cov dej zoo tib yam.
Ntau yam qauv thiab kev siv dav spectrum
Peb tuaj yeem siv cov monomers sib txawv los copolymerize nrog AM kom tau txais PAM sib txawv.
Cov PAMs no muaj qhov sib txawv molecular chain lengths, txawv pawg los yog uncharged pawg. Qhov no tso cai rau lawv los ua ke nrog cov nqi sib txawv thiab cov colloids nyob rau hauv ib puag ncig kev siv sib txawv los ua ntau lub luag haujlwm, xws li flocculation, colloid stabilization, luag txo qis, thiab lwm yam. gas extraction, tuaj yeem ua tiav cov txiaj ntsig zoo.
Kev ua haujlwm yooj yim
Nws yooj yim thiab yooj yim siv PAM, thiab koj tsuas yog ntxiv cov tshuaj rau hauv ib qho kev faib ua feem ntawm cov dej, tom qab ntawd los ntawm kev sib xyaw, kev daws teeb meem thiab lwm cov kauj ruam los ua kom tiav cov txheej txheem kho. Hom kev ua haujlwm yooj yim no tsis yog tsuas yog txo cov tswv yim ntawm cov neeg ua haujlwm thiab cov khoom siv, tab sis kuj txhim kho kev ua haujlwm ntawm kev kho dej.
Vim tias qhov zoo no, PAM tuaj yeem siv rau ntau lub hom phiaj, suav nrog:
PAM tuaj yeem siv ua ib qhoflocculant, uas tuaj yeem tshem tawm cov khoom tshem tawm thiab cov colloids ntawm dej.
PAM tuaj yeem siv rau hauv kev kho sludge li adewatering tus neeg sawv cev. Nws tuaj yeem tsis tsuas yog txo cov dej noo ntawm cov sludge, tab sis kuj txo qhov ntim ntawm sludge.

PAM tuaj yeem siv ua ib qhodispersing tus neeg sawv cevnyob rau hauv daim ntawv kev lag luam, uas muaj peev xwm stabilizes colloids thiaj li ua kom cov ntaub ntawv tshwj xeeb fluffy.
Ntxiv rau, raws li aluag reducer, PAM ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov roj rov qab (EOR). Qhov sib ntxiv ntawm PAM tuaj yeem txo qhov tsis kam ntawm cov dej ntws thiab txhim kho cov dej ntws ntawm cov dej txhaj tshuaj, txhawm rau txhim kho cov roj rov qab.
Txhawm rau ua kom tiav, polyacrylamide nthuav qhia qhov zoo ntawm kev kho dej. Nws tuaj yeem tsis tsuas yog txhim kho cov dej zoo, txo cov tshuaj ntawm cov neeg ua haujlwm, ua kom yooj yim rau kev ua haujlwm, tab sis kuj muaj qhov dav dav thiab txhim kho cov nyhuv ntawm sludge dewatering. Cov txiaj ntsig no ua rau PAM dhau los ua cov tshuaj tseem ceeb hauv kev kho dej. Yog tias koj txaus siab rau kev lag luam flocculants, txais tos rauTiv tauj peb.
