Li-demulsifiers tse seng tsa ionic
Li-demulsifiers tse seng tsa ionic ke li-surfactants tse sa keneng tharollo.Lintho tsena hangata li na le lihlopha tsa polar tse sebelisanang le li-surfactants ka li-emulsion ho li senya.Li sebetsa hantle lits'ebetsong tsa metsi a tlaase le a phahameng a letsoai 'me li ka sebelisoa mefuteng e mengata ea lisebelisoa.

Li-ionic demulsifiers ke li-surfactants tse etsang ionize ka tharollo, li etsa li-ion tse ntle kapa tse mpe tse sebelisanang le li-surfactants tse fapaneng ka har'a li-emulsion.Lintho tsena li atisa ho sebelisoa lits'ebetsong tsa metsi a letsoai le tlaase 'me li ka atleha ho senya li-emulsion tsa metsi ka oli.
Li-demulsifiers tsa cationic
Li-Demulsifiers tsa cationic ke li-surfactants tse nang le "positive charged" tse sebelisanang le li-surfactants tse qosoang hampe ka har'a li-emulsion ho li senya botsitso.Lintho tsena li sebetsa hantle ho senya li-emulsions tsa metsi ka har'a oli 'me li ka sebelisoa lits'ebetsong tsa letsoai le phahameng.Li boetse li khona ho senyeha, 'me li etsa hore li se ke tsa senya tikoloho.
