Polyacrylamide (PAM) Le Tšebeliso ea Eona ka Phekolo ea Metsi

Polyacrylamide (PAM) le ts'ebeliso ea eona kalafong ea metsi

Taolo ea tšilafalo ea metsi le puso ke karolo ea bohlokoa ea ts'ireletso ea tikoloho le ho lahla litšila tsa ho hloekisa metsi ho fumana tlhokomelo e eketsehileng.

Polyacrylamide (PAM), polymer e qhibilihang ka metsing, ke karolo ea bohlokoa haholo tšimong ea phekolo ea metsi ka lebaka la boima bo phahameng ba limolek'hule, ho qhibiliha ha metsi, taolo ea boima ba limolek'hule le liphetoho tse sa tšoaneng tse sebetsang.

PAM le li-derivatives tsa eona li ka sebelisoa e le li-flocculants tse sebetsang hantle, moemeli oa thickening, moemeli oa ho fokotsa ho hula, o sebelisoang haholo ho sebetsana le metsi, ho etsa pampiri, petroleum, mashala, geology, kaho le likarolo tse ling tsa indasteri.

Metsing a ka tlas'a lefatše, holim'a metsi le likhoerekhoere, litšila le litšila hangata li teng ho lekana le likaroloana tse nyane haholo hore li ka lula tlas'a matla a khoheli.Hobane sedimentation ea tlhaho e hlōlehile ho finyella litlhoko, ka thuso ea lik'hemik'hale ho potlakisa ho rarolla theknoloji e sebelisitsoeng tlhahiso.Mohlala, molek'hule ea PAM e monya ka likaroloana tse 'maloa ebe e etsa floc e kholoanyane, ka hona, ho rarolloa ha likaroloana ho potlakisa.

Ha ho bapisoa le inorganic flocculant, PAM e na le melemo e mengata ea bohlokoa: mefuta e mengata ea maemo a fapaneng, ts'ebetso e phahameng, tekanyo e fokolang, ho hlahisoa ha seretse se fokolang, ho bonolo ka mor'a phekolo.Sena se etsa hore e be flocculant e loketseng ka ho fetisisa.

E mabapi le litekanyetso tsa inorganic coagulant 1/30 ho isa ho 1/200.

PAM e rekisoa ka mefuta e 'meli e meholo: phofo le emulsion.

PAM ea phofo e bonolo ho e tsamaisa, empa ha e bonolo ho e sebelisa (lisebelisoa tsa ho qhibiliha lia hlokahala), ha emulsion e se bonolo ho e tsamaisa ebile e na le bophelo bo khutšoanyane ba polokelo.

PAM e na le ho qhibiliha ho hoholo ka metsing, empa e qhibiliha butle haholo.Ho qhala ho ja lihora tse 'maloa kapa bosiu bo le bong.Ho kopanya hantle ho tla thusa ho qhaqha PAM.Ka linako tsohle eketsa PAM ho metsi a futhumetseng - eseng metsi ho PAM.

Ho futhumatsa ho ka eketsa sekhahla sa ho qhibiliha hanyenyane, empa mocheso ha oa lokela ho feta 60°C.

Phaello e phahameng ka ho fetisisa ea PAM ea tharollo ea polymer ke 0.5%, mahloriso a PAM a tlaase a molek'hule a ka hlophisoa ho 1% kapa ho feta hanyenyane.

Tharollo e lokiselitsoeng ea PAM e tlameha ho sebelisoa ka matsatsi a 'maloa, ho seng joalo ts'ebetso ea flocculation e tla ameha.
