PAM qauv txawv
Cationic polyacrylamide (CPAM): linear polymer tebchaw, vim hais tias nws muaj ntau yam active pawg, thiab ntau yam affinity, adsorption los tsim hydrogen bonds. Nws yog qhov yooj yim flocculating qhov tsis zoo them colloid.
Anionic polyacrylamide (APAM): yog cov dej-soluble polymer, feem ntau yog siv rau hauv txhua yam kev lag luam dej khib nyiab flocculation kev daws teeb meem, nag lossis daus kev kho mob, xws li steel zeb khib nyiab, electroplating cog khib nyiab, metallurgical khib nyiab, thee ntxuav dej khib nyiab thiab lwm yam dej phwj tuaj kho, sludge. lub cev qhuav dej. Kuj tseem siv tau rau kev haus dej kom meej meej thiab kev kho kom huv. Vim nws cov saw molecular muaj qee tus naj npawb ntawm cov polar pawg, nws tuaj yeem dhau los ntawm adsorption ntawm cov khoom uas raug tshem tawm hauv dej, txuas ntawm cov khoom los yog los ntawm kev them nyiaj nruab nrab ntawm cov khoom sib xyaw ua ke los tsim cov flocculant loj, yog li nws tuaj yeem ua kom muaj kev sib haum xeeb ntawm cov khoom hauv kev ncua, muaj ib tug heev pom tseeb acceleration ntawm kev daws kom meej, txhawb pom thiab lwm yam teebmeem.
Nonionic polyacrylamide (NPAM): yog ib qho polymer lossis polyelectrolyte, nws cov saw hlau molecular muaj qee qhov ntawm cov noob caj noob ces tuaj yeem nqus cov khoom uas raug tshem tawm hauv dej, kom tus choj ntawm cov khoom los tsim cov flocculant loj. Nws accelerates qhov kev sib haum xeeb ntawm cov khoom nyob rau hauv ncua kev kawm ntawv, accelerates lub clarification ntawm kev daws thiab txhawb kev pom. Vim cov saw molecular muaj amide lossis ion genes, yog li nws cov yam ntxwv zoo kawg li yog hydrophilicity siab, tuaj yeem yaj hauv dej hauv ntau qhov sib npaug, polyacrylamide aqueous kua muaj qhov ua tau zoo ntawm electrolytes, xws li chlorinated amine, sodium sulfate thiab lwm yam tsis yog. rhiab heev, sib xws nrog surfactants.
