Polyacrylamide e bitsoa PAM, 'me e arotsoe ka anion (HPAM) le cation (CPAM).Nonionic (NPAM) ke polymer e nang le mela le e 'ngoe ea mefuta e sebelisoang haholo mefuteng ea polymer e qhibilihang ka metsing.'Me lihlahisoa tsa eona li ka sebelisoa e le li-flocculants tse sebetsang hantle, li-thickeners, li-agent tse matlafatsang pampiri le lisebelisoa tse fokotsang metsi, joalo-joalo, li sebelisoa haholo ho phekola metsi, ho etsa pampiri, peterole, mashala, merafo le metallurgy, geology, masela, kaho, joalo-joalo.
Polyacrylamide e bitsoa No. 3 coagulant, flocculant No. 3;e bitsoa PAM;hangata e bitsoa thuso ea ho boloka pampiring le liindastering tse ling.Hona joale, lihlahisoa tse atisang ho fanoa ke k'hamphani ea rona li tiile (phofo e omileng) le emulsion.
Polyacrylamide e arotsoe ka anionic polyacrylamide;cationic polyacrylamide;polyacrylamide ea nonionic;zwitterionic polyacrylamide;Lebitso la Senyesemane;PAM (acrylamide).
Molao-motheo oa ketso
1) Molao-motheo oa flocculation: ha PAM e sebelisoa bakeng sa ho phalla, e amana le thepa ea holim'a mefuta e mengata, haholo-holo bokhoni ba kinetic, viscosity, turbidity le pH boleng ba ho emisoa.Bokhoni bo matla ba karolo e ka holimo ke lebaka la ho thibela likaroloana.PAM e nang le litefiso tse fapaneng tsa holimo e ka fokotsa bokhoni ba kinetic le kakaretso.
2) Adsorption le borokho: liketane tsa limolek'hule tsa PAM li tsitsitse holim'a likaroloana tse fapaneng, 'me marokho a polymer a thehoa pakeng tsa likaroloana, e le hore likaroloana li thehe lihlopha le ho rarolla.
3) Phatlalatso ea sefahleho: lipapatso tse fapaneng tsa likaroloana tsa sehlopha sa polar ho limolek'hule tsa PAM.
4) Matlafatso: Ketane ea molek'hule ea PAM le mohato o qhalakaneng li ama karolo e hasaneng hammoho ka litlamorao tse fapaneng tsa mochini, tsa 'mele le tsa lik'hemik'hale ho theha marang-rang.
