Njengoko sonke siyazi, iintlobo ezahlukeneyo ze-polyacrylamide zineentlobo ezahlukeneyo zokunyanga kwamanzi amdaka kunye nemiphumo eyahlukeneyo. Ngoko i-polyacrylamide yonke into emhlophe, indlela yokwahlula imodeli yayo?
Kukho iindlela ezi-4 ezilula zokwahlula imodeli yepolyacrylamide:
1. Sonke siyazi ukuba i-cationic polyacrylamide yeyona nto ibiza kakhulu kwimarike, ilandelwa yi-polyacrylamide engeyiyo ionic, kwaye ekugqibeleni i-anionic polyacrylamide. Ukusuka kwixabiso, sinokwenza isigwebo sokuqala kuhlobo lwe-ion.
2. Ukunyibilikisa i-polyacrylamide ukulinganisa ixabiso le-pH yesisombululo. Amaxabiso e-pH ahambelanayo kwiimodeli ezahlukeneyo ahlukile.
3. Okokuqala, khetha i-anionic polyacrylamide kunye neemveliso ze-cationic polyacrylamide, kwaye uzinyibilikise ngokwahlukileyo. Xuba isisombululo semveliso ye-polyacrylamide ukuze uvavanywe ngezisombululo ezimbini ze-PAM. Ukuba isabela kunye nemveliso ye-anionic polyacrylamide, ithetha ukuba i-Polyacrylamide i-cationic. Ukuba isabela nge-cations, ibonisa ukuba imveliso ye-PAM i-anionic okanye i-non-ionic. Ukungalungi kwale ndlela kukuba ayikwazi ukuchonga ngokuchanekileyo ukuba imveliso i-anionic okanye i-polyacrylamide engekho ionic. Kodwa sinokugweba ukusuka kwixesha labo lokuchithwa, i-anion inyibilika ngokukhawuleza kune-non-ion. Ngokuqhelekileyo, i-anion ichithwa ngokupheleleyo kwiyure enye, ngelixa i-non-ion ithatha iyure enye enesiqingatha.
4. Ifakwe kwiimvavanyo zamanzi amdaka, sonke siyazi ukuba i-polyacrylamide cationic Polyacrylamide PAM ifanelekile kumbandela oxhonywe kakubi oqulethe izinto eziphilayo; i-anionic PAM ifanelekile kwi-concentration ephezulu ye-positive charged inorganic suspended matter kunye namasuntswana axhonyiweyo I-Coarse (0.01-1mm), ixabiso le-pH lingathathi hlangothi okanye i-alkaline e-soluble; i-non-ionic polyacrylamide PAM ifanelekile ukwahlulwa kwezinto eziqinileyo ezimisiweyo kwimeko exubeneyo yezinto eziphilayo kunye ne-inorganic, kwaye isisombululo si-acidic okanye singathathi hlangothi. Iiflocs ezenziwe nge-cationic polyacrylamide zinkulu kwaye zixinene, ngelixa iiflocs ezenziwe yi-anion kunye ne-non-ion zincinci kwaye zihlakazekile.
