Njengoko sonke sisazi, iintlobo ezahlukeneyo ze-polyacrylamide zineentlobo ezahlukeneyo zonyango lwamanzi amdaka kunye nemiphumo eyahlukeneyo. Ngoko ke i-polyacrylamide yonke ngamasuntswana amhlophe, ungawuhlula njani umzekelo wayo?
Kukho iindlela ezi-4 ezilula zokwahlula imodeli ye-polyacrylamide:
1. Sonke siyazi ukuba i-cationic polyacrylamide yeyona ibiza kakhulu kwimarike, ilandelwa yi-non-ionic polyacrylamide, kwaye ekugqibeleni yi-anionic polyacrylamide. Ngokwexabiso, singenza isigqibo sokuqala ngohlobo lwe-ion.
2. Nyibilikisa i-polyacrylamide ukuze ulinganise ixabiso le-pH yesisombululo. Amaxabiso e-pH ahambelanayo kwiimodeli ezahlukeneyo ahlukile.
3. Okokuqala, khetha imveliso ye-anionic polyacrylamide kunye ne-cationic polyacrylamide, uze uzinyibilikise ngokwahlukeneyo. Xuba isisombululo semveliso ye-polyacrylamide esiza kuvavanywa ngezisombululo ezibini ze-PAM. Ukuba isabela kwimveliso ye-anionic polyacrylamide, kuthetha ukuba i-Polyacrylamide yi-cationic. Ukuba isabela kwii-cation, ingqina ukuba imveliso ye-PAM yi-anionic okanye ayi-ionic. Ingxaki yale ndlela kukuba ayinakukwazi ukuchonga ngokuchanekileyo ukuba imveliso yi-anionic okanye ayi-ionic polyacrylamide. Kodwa singagweba ngexesha lokunyibilika kwazo, ii-anion ziyanyibilika ngokukhawuleza kakhulu kunee-non-ions. Ngokubanzi, i-anion iyanyibilika ngokupheleleyo kwiyure enye, ngelixa i-non-ion ithatha iyure enesiqingatha.
4. Xa kujongwa kuvavanyo lwelindle, sonke siyazi ukuba i-polyacrylamide cationic polyacrylamide PAM eqhelekileyo ifanelekile kwizinto ezixokonyeziweyo ezitshajwe kakubi eziqulethe izinto eziphilayo; i-anionic PAM ifanelekile kuxinzelelo oluphezulu lwezinto ezixokonyeziweyo ezitshajwe kakuhle kunye neenxalenye ezixokonyeziweyo ezicolekileyo (0.01-1mm), ixabiso le-pH alithathi cala okanye alinyibiliki kwi-alkaline; i-non-ionic polyacrylamide PAM ifanelekile ukwahlula izinto ezixokonyeziweyo kwimeko exutyiweyo yezinto eziphilayo nezingaphiliyo, kwaye isisombululo si-acid okanye asithathi cala. Ii-flocs ezenziwe yi-cationic polyacrylamide zikhulu kwaye zixinene, ngelixa ii-flocs ezenziwe yi-anion kunye nee-non-ion zincinci kwaye zisasazekile.
