Njengoba sonke sazi, izinhlobo ezahlukene ze-polyacrylamide zinezinhlobo ezahlukene zokwelashwa kwendle kanye nemiphumela ehlukene. Ngakho-ke i-polyacrylamide iyizinhlayiya ezimhlophe, ungayihlukanisa kanjani imodeli yayo?
Kunezindlela ezine ezilula zokuhlukanisa imodeli ye-polyacrylamide:
1. Sonke siyazi ukuthi i-cationic polyacrylamide iyona ebiza kakhulu emakethe, ilandelwe yi-non-ionic polyacrylamide, bese kuthi ekugcineni ibe yi-anionic polyacrylamide. Kusukela entengo, singenza isahlulelo sokuqala ngohlobo lwe-ion.
2. Ncibilikisa i-polyacrylamide ukuze ulinganise inani le-pH lesisombululo. Amanani e-pH ahambisanayo amamodeli ahlukahlukene ahlukile.
3. Okokuqala, khetha imikhiqizo ye-anionic polyacrylamide kanye ne-cationic polyacrylamide, bese uyincibilikisa ngokwehlukana. Hlanganisa isisombululo somkhiqizo we-polyacrylamide esizohlolwa ngezixazululo ezimbili ze-PAM. Uma isabela nomkhiqizo we-anionic polyacrylamide, kusho ukuthi i-Polyacrylamide iyi-cationic. Uma isabela ngama-cation, kufakazela ukuthi umkhiqizo we-PAM uyi-anionic noma awuyona i-ionic. Ububi bale ndlela ukuthi ayikwazi ukuhlonza ngokunembile ukuthi umkhiqizo uyi-anionic noma awuyona i-ionic polyacrylamide. Kodwa singahlulela ngesikhathi sokuncibilika kwawo, ama-anion ancibilika ngokushesha kakhulu kune-non-ion. Ngokuvamile, i-anion incibilika ngokuphelele ngehora elilodwa, kuyilapho i-non-ion ithatha ihora elilodwa nesigamu.
4. Uma kucatshangelwa ukuhlolwa kwendle, sonke siyazi ukuthi i-polyacrylamide cationic polyacrylamide PAM ejwayelekile ifaneleka ezintweni ezilengayo ezishajelwe kabi eziqukethe izinto eziphilayo; i-anionic PAM ifaneleka ekugxilweni okuphezulu kwezinto ezilengayo ezishajelwe kahle kanye nezinhlayiya ezilengayo. I-Coarse (0.01-1mm), inani le-pH alithathi hlangothi noma liyancibilika nge-alkaline; i-non-ionic polyacrylamide PAM ifaneleka ukuhlukaniswa kwezinto ezilengayo esimweni esixubile sezinto eziphilayo nezingaphili, kanti ikhambi liyi-acid noma alithathi hlangothi. Ama-floc akhiwe yi-cationic polyacrylamide makhulu futhi aminyene, kuyilapho ama-floc akhiwe yi-anion kanye ne-non-ion emancane futhi ahlakazekile.
