Phapang le ts'ebeliso ea PAM ea cationic, anionic le nonionic?

Polyacrylamide(PAM) ke polymer e feto-fetohang e sebelisoang haholo ho hloekisa metsi, ho etsa pampiri, ho ntša oli le masimo a mang. Ho ea ka thepa ea eona ea ionic, PAM e arotsoe ka mefuta e meraro e meholo: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) le nonionic (Nonionic PAM, NPAM). Mefuta ena e meraro e na le phapang e kholo sebopehong, ts'ebetsong le ts'ebetsong.

1. Cationic polyacrylamide (Cationic PAM, CPAM)

Sebopeho le thepa:

Cationic PAM: Ke motsoako oa polymer o lekanang. Hobane e na le lihlopha tse fapaneng tse sebetsang, e ka theha maqhama a haedrojene ka lintho tse ngata 'me haholo-holo e phalla li-colloid tse nang le molato o fosahetseng. E loketse ho sebelisoa maemong a acidic

Kopo:

- Tlhokomelo ea metsi a litšila: CPAM e atisa ho sebelisoa ho tšoara metsi a litšila a nang le litšila tse mpe, tse kang likhoerekhoere tsa litoropo, metsi a litšila a ho lokisa lijo, joalo-joalo.

- Indasteri ea pampiri: Ts'ebetsong ea ho etsa pampiri, CPAM e ka sebelisoa e le moemeli oa ho matlafatsa le ho boloka ho ntlafatsa matla le lebelo la ho boloka pampiri.

- Ho ntšoa ha oli: Libakeng tsa oli, CPAM e sebelisoa ho phekola seretse sa ho cheka ho fokotsa ho tlhotla le ho teteana.

2. Anionic polyacrylamide (Anionic PAM, APAM)

Sebopeho le thepa:

Anionic PAM ke polima e qhibilihang ka metsing. Ka ho hlahisa lihlopha tsena tsa anionic mokokotlong oa polymer, APAM e ka sebetsana le lintho tse qosoang hantle. E sebelisoa haholo bakeng sa flocculation, sedimentation le ho hlakisoa ha litšila tse fapaneng tsa indasteri. E loketse ho sebelisoa maemong a alkaline.

Kopo:

- Phekolo ea metsi: APAM e sebelisoa haholo ho noa metsi le ho hloekisa metsi a litšila a indasteri. E ka kopanya likaroloana tse emisitsoeng ka ho se nke lehlakore ka motlakase kapa ka adsorption, ka tsela eo e ntlafatsa ho hlaka ha metsi.

- Indasteri ea pampiri: E le thuso ea ho boloka le ho hloekisa, APAM e ka ntlafatsa ts'ebetso ea ho hloekisa metsi ea makhasi le matla a pampiri.

- Merafo le Moaparo oa Ore: Nakong ea ho phaphamala le ho thella ha ore, APAM e ka khothaletsa sedimentation ea likaroloana tsa ore le ho ntlafatsa sekhahla sa ho hlaphoheloa ha ore.

- Ntlafatso ea Mobu: APAM e ka ntlafatsa sebopeho sa mobu, ea fokotsa khoholeho ea mobu, 'me e sebelisoa haholo temong le temong ea lirapa.

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM)

Sebopeho le Thepa:

Nonionic PAM ke polymer e phahameng ea molek'hule kapa polyelectrolyte e nang le palo e itseng ea liphatsa tsa lefutso tsa polar ketane ea eona ea limolek'hule. E ka adsorb likaroloana tse tiileng tse emisitsoeng ka metsing le borokho pakeng tsa likaroloana ho etsa li-floccules tse kholo, ho potlakisa sedimentation ea likaroloana ka ho emisoa, ho potlakisa ho hlakisoa ha tharollo, le ho khothalletsa ho hloekisa. Ha e na lihlopha tse qosoang mme haholo-holo e entsoe ka lihlopha tsa amide. Sebopeho sena se etsa hore se bontše ho qhibiliha hantle le botsitso tlas'a maemo a sa nke lehlakore le a fokolang a acidic. Nonionic PAM e na le litšobotsi tsa boima ba limolek'hule tse phahameng 'me ha e amehe haholo ke pH ea bohlokoa.

Kopo:

- Phekolo ea Metsi: NPAM e ka sebelisoa ho phekola litšila tse tlase, metsi a hloekileng a phahameng, joalo ka metsi a lapeng le metsi a nooang. Molemo oa eona ke hore e na le matla a ho ikamahanya le maemo ho fetoha ha boleng ba metsi le pH.

- Indasteri ea masela le ho daea: Ts'ebetsong ea masela, NPAM e sebelisoa e le setenya le se tsitsitseng ho ntlafatsa ho khomarela dae le ho tšoana ha dae.

- Indasteri ea tšepe: NPAM e sebelisoa e le setlolo le se pholileng ts'ebetsong ea tšepe ho fokotsa likhohlano le ho ntlafatsa ts'ebetso ea ts'ebetso.

- Temo le temo ea lirapa: Joalo ka sets'oants'o sa mobu, NPAM e ka ntlafatsa bokhoni ba ho boloka metsi mobung le ho khothaletsa kholo ea limela.

Cationic, anionic le nonionic polyacrylamide li na le masimo le litlamorao tse fapaneng ka lebaka la sebopeho sa tsona sa lik'hemik'hale tse ikhethang le litšobotsi tsa tefiso. Ho utloisisa le ho khetha se nepahetsengPAMmofuta o ka ntlafatsa haholo ts'ebetso ea ts'ebetso le litlamorao ho fihlela litlhoko tsa liindasteri tse fapaneng.
