Pam rau kev kho dej
Lub hauv paus rau phau ntawv
Pam (polyacrylamide) yog hom polymer siv nyob rau hauv ntau yam kev siv, suav nrog kev kho dej. Polyacrylamide feem ntau yog siv flocculant nyob rau hauv cov txheej txheem dej kho kom txhim kho qhov kev daws teeb meem ntawm kev raug tshem tawm cov lus, ua rau nws yooj yim dua cov khib nyiab los ntawm dej.
Polyacrylamide (PAM) yog cov polymer componed dav siv hauv kev kho cov dej. Nws los nyob rau hauv ntau hom ntau hom, suav nrog kev tsis muaj, cationic, thiab anionic.
Kev Ua Tshwj Xeeb

Cov Ntawv Thov
Floculant:Polyacrylamide feem ntau yog siv los ua cov flocculant hauv cov dej ntws tawm los tshem tawm cov teeb meem uas tsis muaj teeb meem, thiab condens thiab condicens thiab condensing rau kom yooj yim subimented subimentation lossis pom. Cov flocculation no yuav pab txhim kho cov tshuaj kom pom tseeb thiab pob tshab.
Precipitant enhancer:Polyacrylamide tuaj yeem tsim cov complexes nrog hlau ions los txhim kho cov nyhuv ntawm cov precipitant. Thaum kho cov dej khib nyiab uas muaj cov hlau ions, kev siv polyacrylamide tuaj yeem txhim kho cov txiaj ntsig nag los thiab txo cov ntsiab lus ntawm cov hlau ions hauv cov dej khib nyiab.
Tus Antiscalant:Nyob rau hauv cov txheej txheem kev kho dej, polyacrylamide kuj tseem siv tau los ua nplai incharitor kom tiv thaiv kev ntsuas ntawm cov kav dej thiab khoom siv. Nws txhim kho ION sib npaug ntawm cov dej, inhibits qhov tso nyiaj ntawm cov tshuaj uas yaj hauv dej, thiab txo cov kev tsim cov nplai.
Dej Txhim Kho Kev Txhim Kho:Polyacrylamide kuj tseem siv tau los txhim kho cov dej zoo hauv qee kis, xws li nce cov sedimentation tus nqi ntawm cov khib nyiab tshem tawm, thiab lwm yam.
Av Solidification:Nyob rau hauv av solidification thiab corrosionlamide tuaj yeem tsim kho kom ruaj khov thiab corrosion tsis kam ntawm cov av, yog li kev txhim kho lub zog ntawm cov av.
Nws yuav tsum raug sau tseg tias kev tshuaj ntau ntawm polyacrylamide yuav tsum tau ua tib zoo tswj lub sijhawm siv kom tsis txhob muaj kev cuam tshuam zoo nyob rau ib puag ncig. Ib qho ntxiv, cov ntawv thov tshwj xeeb yog nyob ntawm qhov kev xav tau ntawm kev kho cov dej thiab cov yam ntxwv ua dej.
