Polyacrylamide
Polyacrylamide ke lesela polymer, sehlahisoa se haholo-holo arotsoe ka phofo omileng le colloidal mefuta e 'meli. Ho latela boima ba eona ba limolek'hule, e ka aroloa ka boima bo tlase ba limolek'hule (<milione e le 'ngoe), boima bo mahareng ba limolek'hule (2 ~ 4 milione) le boima bo phahameng ba limolek'hule (> .7 milione). - ionic, anion le cationic. Ho qhalana ha metsi (HPAM) ea mofuta oa anion. Letoto la mantlha la polyacrylamide le na le palo e kholo ea lihlopha tsa amide, tse nang le tšebetso e phahameng ea lik'hemik'hale, 'me li ka fetoloa ho hlahisa lihlahisoa tse ngata tsa polyacrylamide. Lihlahisoa li sebelisitsoe haholo ho etsa pampiri, ts'ebetso ea diminerale, ho qhekelloa ha oli, tšepe, lisebelisoa tsa kaho, kalafo ea likhoerekhoere le liindasteri tse ling. Joaloka lubricant, moemeli oa ho emisa, botsitso ba letsopa, moemeli oa phalliso ea oli, moemeli oa tahlehelo ea metsi le moemeli oa thickening, polyacrylamide e sebelisitsoe haholo ho cheka, acidification, fracturing, plug ea metsi, ho tiisa, ho hlaphoheloa hoa oli ea bobeli le ho hlaphoheloa ha oli e phahameng.
