PAM rau kev kho dej
Taw qhia
PAM (Polyacrylamide) yog ib hom polymer siv ntau yam kev siv, suav nrog kev kho dej. Polyacrylamide feem ntau yog siv los ua flocculant hauv cov txheej txheem kho dej los txhim kho qhov kev daws teeb meem ntawm cov khoom tshem tawm, ua kom yooj yim cais cov khib nyiab ntawm dej.
Polyacrylamide (PAM) yog cov khoom siv polymer dav siv hauv kev kho dej. Nws tuaj nyob rau hauv ntau yam sib txawv, xws li nonionic, cationic, thiab anionic.

Daim ntawv thov
Floculant:Polyacrylamide feem ntau yog siv los ua flocculant hauv kev kho dej kom tshem tawm cov khib nyiab pov tseg, cov khoom me me thiab cov colloids thiab condense lawv mus rau hauv loj flocs los pab txhawb cov sedimentation los yog pom. Qhov flocculation no pab txhim kho cov dej ntshiab thiab pob tshab.
Precipitant enhancer:Polyacrylamide tuaj yeem tsim cov complexes nrog hlau ions los txhim kho cov nyhuv ntawm cov dej nag. Thaum kho cov dej khib nyiab uas muaj hlau ions, kev siv cov polyacrylamide tuaj yeem txhim kho cov nag lossis daus thiab txo cov ntsiab lus ntawm cov hlau ions hauv cov dej khib nyiab.
Antiscalant:Hauv cov txheej txheem kev kho dej, polyacrylamide kuj tuaj yeem siv los ua cov nplai inhibitor los tiv thaiv kev scaling ntawm cov kav dej thiab cov khoom siv. Nws txhim kho cov ion sib npaug ntawm cov dej, inhibits cov deposition ntawm yaj nyob rau hauv dej, thiab txo qhov tsim ntawm scale.
Kev txhim kho dej zoo:Polyacrylamide kuj tseem siv tau los txhim kho cov dej zoo hauv qee qhov, xws li nce cov sedimentation ntawm cov khib nyiab hauv dej, txo cov sludge tsim, thiab lwm yam.
Av solidification:Hauv av solidification thiab txhim kho, polyacrylamide tuaj yeem siv los txhim kho kev ruaj ntseg thiab corrosion tsis kam ntawm cov av, yog li kev txhim kho lub cev ntawm cov av.
Nws yuav tsum raug sau tseg tias ntau npaum li cas ntawm polyacrylamide yuav tsum tau ua tib zoo tswj thaum siv kom tsis txhob muaj kev phom sij rau ib puag ncig. Tsis tas li ntawd, daim ntawv thov tshwj xeeb yog nyob ntawm qhov kev xav tau ntawm kev kho dej thiab cov yam ntxwv zoo ntawm cov dej.
