Njengoba sonke sazi, izinhlobo ezahlukene ze-polyacrylamide zinezinhlobo ezahlukene zokwelashwa kwendle kanye nemiphumela ehlukene.Ngakho-ke i-polyacrylamide yizo zonke izinhlayiya ezimhlophe, indlela yokuhlukanisa imodeli yayo?
Kunezindlela ezi-4 ezilula zokuhlukanisa imodeli ye-polyacrylamide:
1. Sonke siyazi ukuthi i-cationic polyacrylamide ibiza kakhulu emakethe, ilandelwa i-polyacrylamide engeyona i-ionic, futhi ekugcineni i-anionic polyacrylamide.Kusukela enanini, singenza isahlulelo sokuqala ngohlobo lwe-ion.
2. Chaza i-polyacrylamide ukukala inani le-pH lekhambi.Amanani e-pH ahambisanayo amamodeli ahlukahlukene ahlukile.
3. Okokuqala, khetha i-anionic polyacrylamide kanye nemikhiqizo ye-cationic Polyacrylamide, bese uyincibilikisa ngokwehlukana.Hlanganisa isixazululo somkhiqizo we-polyacrylamide ukuze uhlolwe ngezixazululo ezimbili ze-PAM.Uma ihlangana nomkhiqizo we-anionic polyacrylamide, kusho ukuthi i-Polyacrylamide i-cationic.Uma ihlangana nama-cations, ifakazela ukuthi umkhiqizo we-PAM uyi-anionic noma awuwona i-ionic.Ububi bale ndlela ukuthi ayikwazi ukukhomba ngokunembile ukuthi umkhiqizo uyi-anionic noma i-polyacrylamide engeyona ionic.Kodwa singahlulela kusukela esikhathini sokuhlakazwa kwawo, ama-anion ancibilika ngokushesha kakhulu kunangewona ama-ion.Ngokuvamile, i-anion ichitheka ngokuphelele ehoreni elilodwa, kanti i-non-ion ithatha ihora nesigamu.
4. Ngokusekelwe ekuhlolweni kwendle, sonke siyazi ukuthi i-polyacrylamide cationic polyacrylamide PAM evamile ifaneleka odaba olumiswe kabi olumiswe okwesikhashana oluqukethe izinto eziphilayo;i-anionic PAM ifanele ukugxiliswa okuphezulu kwento emisiwe ekhokhiswa kahle nezinhlayiya ezimisiwe I-Coarse (0.01-1mm), inani le-pH alithathi hlangothi noma liyancibilika nge-alkaline;i-non-ionic polyacrylamide PAM ifanele ukuhlukaniswa kwezinto eziqinile ezimisiwe esimweni esixubile se-organic and inorganic, futhi isixazululo sine-acidic noma singathathi hlangothi.Ama-flocs akhiwa i-cationic polyacrylamide mikhulu futhi aminyene, kuyilapho ama-flocs akhiwa i-anion kanye ne-non-ion mancane futhi ahlakazekile.
