Phekolo ea Metsi a Litšila tsa indasteri - Flocculants (PAM)

Metsing a litšila a indasteri, ka linako tse ling ho na le litšila tse etsang hore metsi a be le maru, e leng se etsang hore metsi ana a litšila a be thata ho hloekisa. Hoa hlokahala ho sebelisa flocculant ho etsa hore metsi a hlake ho finyella maemo a ho ntša metsi. Bakeng sa flocculant ena, re khothaletsapolyacrylamide (PAM).

Flocculantbakeng sa ho hloekisa metsi a litšila a indasteri

Polyacrylamide ke polima e qhibilihang ka metsing. Ketane ea eona ea limolek'hule e na le lihlopha tsa polar, tse ka khonang ho hlahisa likaroloana tse emisitsoeng ka har'a tharollo le ho kopanya likaroloana ho etsa lihlopha tse kholoanyane. Li-flocs tse kholo tse entsoeng li ka potlakisa pula ea likaroloana tse emisitsoeng le ho potlakisa phello ea tlhaloso ea tharollo. Ha ho bapisoa le phekolo e tloaelehileng ea metsi a litšila, phekolo ea metsi a litšila ea lik'hemik'hale e rarahane haholo. Ts'ebetsong ea ho hloekisa metsi a litšila a lik'hemik'hale, lisebelisoa tse fapaneng tse kang li-flocculants, coagulants le li-decolorizer lia hlokahala. Har'a bona, flocculant e sebelisoang hangata ke nonionic polyacrylamide.

Mokhoa oa nts'etsopele ea polyacrylamide

1. Polyacrylamide molecular chain e na le lihlopha tsa polar, tse khonang ho monya likaroloana tse emisitsoeng ka metsing le borokho pakeng tsa likaroloana ho etsa lihlopha tse kholoanyane.

2. Polyacrylamide e seng ionic e ka potlakisa pula ea likaroloana tse emisitsoeng ka ho etsa li-flocs tse khōloanyane, kahoo e potlakisa ho hlakisoa ha tharollo le ho khothalletsa phello ea filtration.

3. Har'a lihlahisoa tsohle tsa flocculant, polyacrylamide e seng ionic e na le phello e ntle ea ho phekola metsi a litšila a acidic, 'me metsi a litšila a lik'hemik'hale hangata a na le asiti. Ka hona, polyacrylamide e seng ionic e na le melemo e ikhethang hophekolo ea metsi a litšila ka lik'hemik'hale.

4. Coagulant e ka sebelisoa hammoho le matsoai a sa tloaelehang a kang polyaluminium, polyiron le li-flocculants tse ling, 'me phello e molemo. Ke hantle ka lebaka la litšobotsi tsa polyacrylamide e seng ionic hore e na le melemo e totobetseng ea ho phekola metsi a litšila a lik'hemik'hale.

Re fana ka PAM ea boleng bo phahameng bakeng sa phepelo ea pele ea fektheri, e le hore u ka fumana PAM e theko e tlaase le phihlelo e khotsofatsang ka mor'a ho rekisa.
