Lihlahisoa tse fetotsoeng tsa polyacrylamide tse sebelisoang e le lithuso tsa ho boloka le ho ntša metsi ha ho etsoa pampiri hangata ke lihlahisoa tse fetotsoeng tsa polyacrylamide, ho kenyeletsoa anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM) le amphoteric polyacrylamide (AmPAM), e nang le boima ba limolek'hule tse limilione tse 2 ~ 4 milione. .
Ka kakaretso, APAM e theha tsamaiso e rarahaneng e nang le metsoako e meng ea cationic ho bapala phello e matla ea ho boloka.Ka mohlala, ho kopanya le aluminium sulfate ho ka etsa hore APAM e tlamahane haufi-ufi le likhoele, likhoele tse ntle, li-fillers, joalo-joalo, kahoo ho ntlafatsa haholo ho boloka likhoele tse ntle le li-fillers.Sekhahla sa tlhokomelo.
CPAM ke e 'ngoe ea lithuso tsa ho boloka tse sebelisoang hangata ha ho etsoa pampiri, 'me lihlahisoa tse nang le boima bo phahameng ba limolek'hule le tefiso e tlase li sebelisoa hangata.Tefiso ea eona e khahlanong le ea fiber, 'me e ka sebelisoa e le mong kapa e kopantsoe le bentonite, anion, joalo-joalo, ho baka flocculation ea pampiri ka mochine oa borokho holim'a thepa ea pampiri,' me e ka eketsa lebelo la ho boloka. pampiri ea ho tlatsa pampiri le ho khothaletsa Motsoako oa metsi a masoeu tlas'a letlooa a fokotsehile.Ha CPAM le li-bentonite tse qosoang hampe li sebelisoa ho theha mokhoa oa ho boloka likaroloana le tsamaiso ea metsi, boholo ba lihlopha tsa thepa ea pampiri e entsoeng ka ho eketsa CPAM e batla e le khōlō, 'me ka mor'a hore e be tlas'a matla a phahameng a ho kuta ka mor'a ho feta pompong ea pulp le. lisebelisoa tse ling, li-flocs li robehile likotoana tse nyenyane, 'me ho eketsoa ha bentonite e qosoa hampe ka nako ena ho tla boela ho borokhoe likhechana tse nyenyane le ho etsa lihlopha tse nyenyane ho feta tse qalileng ho thehoa ke CPAM.Ka hona, sekhahla sa ho boloka thepa ea pampiri se ntlafatsoa, 'me ts'ebetso ea ho lekana le ea drainage ea pampiri e batla e ntlafala.
Ha AMPAM e sebelisoa e le thuso ea ho boloka le ho ntša metsi, lihlopha tsa anionic li leleka litšila tsa anionic ka har'a makhasi, 'me lihlopha tsa cationic li kopanya le likhoele le likhoele tse ntle.Ka hona, sekhahla sa ho boloka li-fiber tse ntle se ntlafatsoa hantle.
