Karolo ea Boselamose ea Polyacrylamide Lefapheng la ho Etsa Lipampiri

Polyacrylamideke lentsoe le akaretsang bakeng sa li-homopolymers tsa acrylamide kapa copolymers le li-monomer tse ling. Ke e 'ngoe ea li-polymer tse qhibilihang ka metsing tse sebelisoang haholo. Polyacrylamide e teng ka sebōpeho sa li-granules tse tšoeu 'me e ka aroloa ka mefuta e mene: non-ionic, anionic, cationic, le amphoteric ionic.

Lisebelisoa tsa Polyacrylamide Lefapheng la ho Etsa Pampiri

Ts'ebetso ea ho etsa pampiri e na le mekhahlelo e mengata, ho kenyelletsa ho phunya, ho hlahloba, ho hloekisa, ho hloekisa le ho etsa. Nakong ea ts'ebetso ena, ho hlahisoa litšila tse fapaneng tse kang likhoele, li-fillers le likotlo. Haeba litšila tsena li sa tlosoe ka mokhoa o nepahetseng ho tsoa ho makhasi, li ka lebisa mathateng a kang metsi a fokolang le matla a tlaase a pampiri. Polyacrylamide e sebelisoa haholo-holo e le dispersant, thuso ea ho boloka, thuso ea drainage, flocculant, le mokhoa oa ho etsa lipampiri.

Ⅰ. Ea qhalaneng

Ho eketsa dispersant polyacrylamide nakong ea ho etsa papermaking ho ka thibela ka katleho ho kopana ha likhoele le ho ntlafatsa ho tšoana ha pampiri. Keketso e tlase e ka khothaletsa phallo e ntle ea likhoele tsa ho etsa pampiri le ho fihlela phello e ntle haholo ea ho etsa pampiri. E ka boela ea ntlafatsa ho tšoana ha pulp le bonolo ba pampiri, le ho ntlafatsa matla a pampiri. E loketse lihlahisoa tse fapaneng tsa pampiri tsa ntlo tse kang pampiri ea ntloana, li-napkins, lisele tsa sefahleho le lipampiri tse ling tse tšesaane. Litsing tse ling tsa pampiri, e ka nka sebaka sa Polyethylene Oxide (PEO) ka botlalo.

Ⅱ. Thuso ea ho Boloka

PAM e atisa ho sebelisoa e le thuso ea ho boloka indasteri ea ho etsa pampiri ho eketsa tekanyo ea ho boloka fiber le ho fokotsa ho tsoa ha likhoerekhoere. Molao-motheo oa eona oa ho sebetsa ke ho etsa li-flocs tse kholo tse nang le likaroloana tse nyenyane, tse ka tlosoang habonolo ho tloha ho makhasi ka ho hloekisa kapa ho senya.

Ⅲ. Thuso ea ho ntša metsi

PAM e ka boela ea sebetsa e le thuso ea metsi mosebetsing oa ho etsa pampiri. E eketsa lebelo la ho ntša metsi, e leng ho nolofalletsang ho ntša metsi ka potlako le ka mokhoa o sebetsang haholoanyane oa pampiri mochine 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. Sizing Agent

Maemong a mang, polyacrylamide e sebelisoa e le sesebelisoa sa ho etsa lipampiri ho laola ho kenella ha metsi le lino tse ling ka har'a pampiri ea pampiri. Sena se thusa ho fihlela thepa e lakatsehang joalo ka ho hanyetsa metsi le ho ts'oara enke, haholo lits'ebetsong moo pampiri e hlokang ho mamella mongobo kapa lits'ebetso tsa khatiso.

Ⅴ. Flocculant

Nakong ea ts'ebetso ea kalafo ea metsi a litšila ka limiloneng tsa pampiri, polyacrylamide e ka sebelisoa e le flocculant ho tlosa lintho tse tiileng le tse silafatsang metsing a litšila. E thusa ho theha likaroloana tse kholo tse bitsoang li-flocs, tse ka tlosoang habonolo ka mokhoa oa sedimentation kapa filtration. Sena se kenya letsoho ho fokotsa tšilafalo ea metsi le ho ntlafatsa ts'ebetso ea tikoloho ea 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 ntlafatsong ea ts'ebetso, 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 tlhahiso ea pampiri ho ea ho hloekisa metsi a litšila. Ha e ntlafatse feela boleng le katleho ea tlhahiso ea pampiri, e fokotsa litšenyehelo tsa tlhahiso, empa hape e fana ka tlatsetso e ntle ho sireletsa tikoloho.
