Sezvatinoziva tese, mhando dzakasiyana dzepolyacrylamide dzine mhando dzakasiyana dzekuchenesa tsvina uye mhedzisiro dzakasiyana. Saka polyacrylamide zvese zvimedu zvichena, ungasiyanisa sei modhi yayo?
Kune nzira ina dziri nyore dzekusiyanisa muenzaniso wepolyacrylamide:
1. Tose tinoziva kuti cationic polyacrylamide ndiyo inodhura zvakanyanya pamusika, ichiteverwa ne non-ionic polyacrylamide, uye pakupedzisira anionic polyacrylamide. Kubva pamutengo, tinogona kuita mutongo wekutanga pamusoro perudzi rweion.
2. Nyungudutsa polyacrylamide kuti uverenge pH yemushonga. pH inoenderana nemamodheru akasiyana-siyana yakasiyana.
3. Kutanga, sarudza zvigadzirwa zve anionic polyacrylamide ne cationic polyacrylamide, wozvinyungudutsa zvakasiyana. Sanganisa mhinduro yechigadzirwa che polyacrylamide kuti iedzwe nemhinduro mbiri dzePAM. Kana ikaita ne anionic polyacrylamide chigadzirwa, zvinoreva kuti Polyacrylamide i cationic. Kana ikaita ne cations, zvinoratidza kuti chigadzirwa chePAM i anionic kana kuti kwete ionic. Dambudziko renzira iyi nderekuti haigone kuziva nemazvo kana chigadzirwa chacho chiri anionic kana kuti kwete ionic polyacrylamide. Asi tinogona kutonga kubva panguva yekunyunguduka kwadzo, anions dzinonyunguduka nekukurumidza kupfuura non-ions. Kazhinji, anion inonyunguduka zvachose muawa imwe chete, nepo non-ion ichitora awa imwe nehafu.
4. Kubva mukuyedza kwetsvina, tese tinoziva kuti general polyacrylamide cationic polyacrylamide PAM yakakodzera zvinhu zvakasungirirwa zvine organic; anionic PAM yakakodzera kuwanda kwezvinhu zvakasungirirwa zvisina organic zvakasungirirwa zvine positive charge uye suspended particles Coarse (0.01-1mm), pH value haina neutral kana alkaline soluble; non-ionic polyacrylamide PAM yakakodzera kupatsanurwa kwezvinhu zvakasungirirwa zvine organic ne inorganic, uye mhinduro yacho ine acidic kana neutral. Maflocs akaumbwa necationic polyacrylamide akakura uye akasimba, nepo flocs akaumbwa neanion ne non-ion ari madiki uye akapararira.
