Karolo ea Boselamose ea Polyacrylamide Tšimong ea ho Etsa Pampiri

Polyacrylamideke lentsoe le akaretsang bakeng sa li-homopolymer tsa acrylamide kapa li-copolymer tse nang le li-monomers tse ling. Ke e 'ngoe ea li-polymer tse qhibilihang ka metsing tse sebelisoang haholo. Polyacrylamide e teng ka mokhoa oa li-granule tse tšoeu 'me e ka aroloa ka mefuta e mene: ionic e seng ea ionic, anionic, cationic, le amphoteric ionic.

Tšebeliso ea Polyacrylamide Tšimong ea ho Etsa Pampiri

Ts'ebetso ea ho etsa pampiri e na le mekhahlelo e 'maloa, ho kenyeletsoa ho pulpa, ho hlahloba, ho hloekisa, ho hloekisa le ho bopa. Nakong ea lits'ebetso tsena, litšila tse fapaneng tse kang likhoele, li-filler le li-fine lia hlahisoa. Haeba litšila tsena li sa tlosoe hantle ho pulpa, li ka lebisa mathateng a kang ho ntsha metsi hampe le matla a tlase a pampiri. Polyacrylamide e sebelisoa haholo e le disaspensant, thuso ea ho boloka, thuso ea ho ntsha metsi, flocculant, le moemeli oa boholo ts'ebetsong ea ho etsa pampiri.

Ⅰ. Sehatsetsi

Ho eketsa polyacrylamide dispersant nakong ea ts'ebetso ea ho etsa pampiri ho ka thibela ho kopana ha likhoele ka katleho le ho ntlafatsa ho tšoana ha pampiri. Palo e tlase ea ho eketsa e ka khothaletsa ho hasana ho hotle ha likhoele tsa ho etsa pampiri le ho fihlela phello e ntle ea ho etsa pampiri. E ka boela ea ntlafatsa ho tšoana ha pulp le bonolo ba pampiri, le ho ntlafatsa litšobotsi tsa matla a pampiri. E loketse lihlahisoa tse fapaneng tsa pampiri ea lapeng tse kang pampiri ea ntloana, li-napkin, lisele tsa sefahleho le lipampiri tse ling tse tšesaane. Libakeng tse ling tsa lipampiri, e ka nkela Polyethylene Oxide (PEO) sebaka ka botlalo.

Ⅱ. Thuso ea ho Boloka

PAM e atisa ho sebelisoa e le thuso ea ho boloka lintho indastering ea ho etsa pampiri ho eketsa sekhahla sa ho boloka lintho tse nang le fiber le ho fokotsa ho ntšoa ha likhoerekhoere. Molao-motheo oa eona o sebetsang ke ho etsa li-floc tse kholo tse nang le likaroloana tse nyane, tse ka tlosoang habonolo ho tloha pulp ka ho sefa kapa ho senngoa ha mobu.

Ⅲ. Thuso ea ho ntša metsi

PAM e ka boela ea sebetsa e le thuso ea ho ntša metsi ts'ebetsong ea ho etsa pampiri. E eketsa sekhahla sa ho ntša metsi, e nolofalletsa ho tlosa metsi ka potlako le ka katleho pampiring mochining oa pampiri. Sena se thusa ho eketsa lebelo la tlhahiso le ho fokotsa tšebeliso ea matla ka ho khutsufatsa nako ea ho omisa e hlokahalang bakeng sa pampiri.

Ⅳ. Moemeli oa ho lekanya boholo

Maemong a mang, polyacrylamide e sebediswa e le sesebelisoa sa ho lekanya boholo ba pampiri ho laola ho kenella ha metsi le diedi tse ding ka hara pampiri. Sena se thusa ho fihlella dibopeho tse lakatsehang tse kang ho hanyetsa metsi le ho tshwarella ha enke, haholoholo ditshebedisong moo pampiri e hlokang ho mamella mongobo kapa mekgwa ya ho hatisa.

Ⅴ. Flocculant

Nakong ea ts'ebetso ea kalafo ea metsi a litšila lifemeng tsa pampiri, polyacrylamide e ka sebelisoa e le flocculant ho tlosa lintho tse tiileng tse emisitsoeng le litšila metsing a litšila. E thusa ho theha likaroloana tse kholoanyane tse bitsoang flocs, tse ka tlosoang habonolo ka mokhoa oa ho sefa kapa oa ho sefa. Sena se thusa ho fokotsa tšilafalo ea metsi le ho ntlafatsa botsitso ba tikoloho ba khoebo ea ho etsa pampiri.

Ka kakaretso, thepa e feto-fetohang ea polyacrylamide e etsa hore e be tlatsetso ea bohlokoa indastering ea ho etsa pampiri, e tlatsetsang ho ntlafatseng bokgoni, boleng ba sehlahisoa le ts'ebetso ea lihlahisoa tsa pampiri. Tšebeliso ea polyacrylamide tšimong ea ho etsa pampiri e akaretsa ketane eohle ea indasteri ea ho etsa pampiri, ho tloha tlhahisong ea pampiri ho ea kalafong ea metsi a litšila. Ha e ntlafatse boleng le katleho ea tlhahiso ea pampiri feela, e fokotsa litšenyehelo tsa tlhahiso, empa hape e etsa monehelo o motle ts'ireletsong ea tikoloho.
