Polyacrylamide ke linear polymer, sehlahiswa haholo-holo arotsoe ka phofo omileng le colloidal mefuta e 'meli. Ho ea ka boima ba eona bo tloaelehileng ba limolek'hule, e ka aroloa ka boima bo tlaase ba limolek'hule (<1 milione), boima ba molek'hule bo bohareng (2 ~ 4 milione) le boima bo phahameng ba limolek'hule (> .7 milione) . - ionic, anion le cationic. Ho arohana ha metsi (HPAM) ea mofuta oa anion. Ketane e ka sehloohong ea polyacrylamide e na le palo e kholo ea lihlopha tsa amide, tse nang le ts'ebetso e phahameng ea lik'hemik'hale, 'me e ka fetoloa ho hlahisa lihlahisoa tse ngata tsa polyacrylamide. Lihlahisoa li 'nile tsa sebelisoa haholo ho etsa pampiri, ho sebetsa ka liminerale, ho ntša oli, metallurgy, thepa ea mohaho, ho hloekisa likhoerekhoere le liindasteri tse ling. Joalo ka setlolo, moemeli oa ho emisoa, botsitso ba letsopa, moemeli oa phalliso oa oli, sesebelisoa se fokotsang tahlehelo ea metsi le motenya, polyacrylamide e 'nile ea sebelisoa haholo ho cheka, acidification, fracturing, plugging ea metsi, cementing, ho hlaphoheloa ha oli ea bobeli le ho hlaphoheloa ha oli ea thuto e phahameng.

1.Ho hatisa le ho daea kalafo ea metsi a litšila

Ho hatisa le ho daea kalafo ea metsi a litšila, sebakeng sa li-coagulants tsa setso tse tlase tsa molek'hule, tse amanang le tekanyetso e kholo ea setso ea coagulant, ts'ebetso ea coagulation e phahame, maemo a nepahetseng a ph ka tsela e latelang: 8.0.

2.Ho etsa pampiri ea ho hloekisa metsi a litšila

Phekolo ea metsi a litšila ea pampiri, e sebelisoang e le coagulant ho e-na le polyaluminium chloride, aluminium sulfate, joalo-joalo, e ka sebelisoa hape e le ho ntša metsi a litšila tsa pampiri.
