Jwalo ka ha re tseba kaofela, mefuta e fapaneng ya polyacrylamide e na le mefuta e fapaneng ya kalafo ya dikgwerekgwere le ditlamorao tse fapaneng. Kahoo polyacrylamide ke dikarolwana tse tshweu kaofela, mohlala wa yona o ka kgetholoha jwang?
Ho na le litsela tse 4 tse bonolo tsa ho khetholla mohlala oa polyacrylamide:
1. Kaofela rea tseba hore polyacrylamide ea cationic ke eona e turang ka ho fetisisa 'marakeng, e lateloa ke polyacrylamide e seng ea ionic, 'me qetellong ke polyacrylamide ea anionic. Ho latela theko, re ka etsa qeto ea pele ka mofuta oa ion.
2. Qhibilihisa polyacrylamide ho lekanya boleng ba pH ba tharollo. Boleng ba pH bo tsamaellanang ba mehlala e fapaneng bo fapane.
3. Taba ea pele, khetha lihlahisoa tsa polyacrylamide ea anionic le cationic, 'me u li qhale ka thoko. Kopanya tharollo ea sehlahisoa sa polyacrylamide e tla lekoa ka litharollo tse peli tsa PAM. Haeba e arabela le sehlahisoa sa polyacrylamide ea anionic, ho bolela hore Polyacrylamide ke cationic. Haeba e arabela le li-cation, ho paka hore sehlahisoa sa PAM ke anionic kapa non-ionic. Bothata ba mokhoa ona ke hore ha o khone ho khetholla ka nepo hore na sehlahisoa ke anionic kapa non-ionic polyacrylamide. Empa re ka ahlola ho latela nako ea tsona ea ho qhibiliha, li-anion lia qhibiliha kapele haholo ho feta tse seng tsa ionic. Ka kakaretso, anion e qhibiliha ka botlalo ka hora e le 'ngoe, ha non-ion e nka hora le halofo.
4. Ha re nahana ka liteko tsa likhoerekhoere, kaofela rea tseba hore polyacrylamide cationic polyacrylamide PAM e akaretsang e loketse lintho tse emisitsoeng tse nang le tjhaja e mpe tse nang le lintho tse phelang; anionic PAM e loketse khatello e phahameng ea lintho tse emisitsoeng tse nang le tjhaja e ntle le likaroloana tse emisitsoeng tse Mahoashe (0.01-1mm), boleng ba pH ha bo nke lehlakore kapa bo qhibiliha ka alkaline; non-ionic polyacrylamide PAM e loketse karohano ea lintho tse tiileng tse emisitsoeng boemong bo tsoakiloeng ba lintho tse phelang le tse sa pheleng, 'me tharollo e na le asiti kapa e sa nke lehlakore. Li-floc tse entsoeng ke cationic polyacrylamide li kholo ebile li teteaneng, ha li-floc tse entsoeng ke anion le non-ion li le nyane ebile li hasane.
