Mohato oa bohlokoa ts'ebetsong ea kalafo ea metsi a litšila ke ho hoama le ho lula ha lintho tse tiileng tse emisitsoeng, ts'ebetso e itšetlehileng haholo-holo ka lik'hemik'hale tse bitsoang flocculants. Ho sena, li-polymer li bapala karolo ea bohlokoa, kahoo PAM, li-polyamine. Sengoloa sena se tla hlahloba tse tloaelehilengli-flocculant tsa polymer, ts'ebeliso ea li-polymer e le li-flocculant kalafong ea metsi a litšila, le mesebetsi e ka morao ho tsona.
Li-flocculant tsa polymer tse sebelisoang haholo ke life?
Li-flocculant tsa polymer tse sebelisoang hangata li kenyelletsa li-polymer tsa cationic, li-polymer tsa anionic le li-polymer tse seng tsa ionic. Li-polymer tsena li ka fumanoa ka mekhoa e fapaneng ea maiketsetso 'me li na le meaho e fapaneng ea cationic le makala. Litšebelisong tse sebetsang, hoa hlokahala ho khetha li-flocculant tse loketseng tsa polymer ho latela maemo a itseng a metsi a litšila ho fumana phello e ntle ka ho fetisisa ea kalafo. PAM, polyDADMAC, e sebelisoa haholo kalafong ea metsi a litšila ea indasteri. Polyacrylamide ke flocculant e sebelisoang haholo lefatšeng. Li-polymer tsena tse qhibilihang metsing ke tsa maiketsetso 'me li ka etsoa ka mokhoa o ikhethileng bakeng sa lits'ebetso tse ikhethileng ka boima bo fapaneng ba limolek'hule, viscosities, likhato tse fapaneng tsa tefiso, mefuta e fapaneng joalo ka likaroloana, li-emulsion, jj. PolyDADMAC e sebelisoa haholo metsing a pompo, flocculation ea metsi a tala, ho felloa ke metsi ha seretse, indasteri ea pampiri le indasteri ea khatiso le ho daea.
Tšebeliso ea li-flocculant kalafong ea metsi a litšila
Sepheo se seholo sa kalafo ya metsi a ditshila ke ho tlosa ditshila tse kang dintho tse tiileng tse emisitsweng, dintho tse qhibilihisitsweng tsa tlhaho le dikarolwana tsa colloidal metsing ho ntlafatsa boleng ba metsi. Ts'ebetsong ena, di-flocculant di bapala karolo ya bohlokwa. Ka ho sebedisa di-flocculant, dikarolwana tse nyane le dintho tsa colloidal tse ka metsing di ka bakwa ke ho kopana ho ba di-floc tse kgolo, tse ka tloswang habonolo ka ho senyeha kapa ho sefa. Sena ha se ntlafatse boleng ba metsi feela, empa hape se ka ntlafatsa bokgoni ba kalafo le ho fokotsa ditjeo tsa kalafo.
Ke hobane'ng ha li-polymer li ka etsa li-flocculant?
Li-polymer li ka sebelisoa e le li-flocculant haholo-holo ka lebaka la boima ba tsona bo phahameng ba limolek'hule le sebopeho sa makala a mangata. Litšobotsi tsena li lumella polymer ho monya lintho tse nyenyane hamolemo, ho etsa li-floc tse kholoanyane tse ka lulang kapele. Ho phaella moo, li-polymer li ka felisa ho repulsion ha motlakase pakeng tsa likaroloana ka ho fokotsa matla a motlakase, ho lumella likaroloana ho atamela le ho kopana hammoho.
Mokhoa oa ts'ebetso ea li-polymer kalafong ea metsi a litšila
Mokhoa oa tšebetso oa li-polymer e le li-flocculant o ka aroloa ka mehato e meraro: ho se be le tjhaja, ho koala flocculation le ho hapa letlooa. Taba ea pele, polymer e felisa ho sutumelletsa ha motlakase pakeng tsa likaroloana ka ho se be le tjhaja, e leng se lumellang likaroloana ho atamela. Joale polymer e hokahanya likaroloana ho etsa li-floc tse kholoanyane ka ho koala flocculation. Qetellong, li-floc tsena li kopanngoa le ho lula ka metsing ka ho hula matlooa.
Mabaka a amang bokgoni ba di-polymer ho hlwekiseng metsi a ditshila
Ho na le mabaka a mangata a amang katleho ea kalafo ea polymer ea metsi a litšila, ho kenyeletsoa mofuta oa polymer, tekanyo, boleng ba pH, mocheso, lebelo la ho hlohlelletsa, jj. Har'a 'ona, mofuta oa polymer le tekanyo ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa. Mefuta e fapaneng ea li-polymer e na le litšobotsi tse fapaneng tsa tjhaja le kabo ea boima ba limolek'hule, kahoo hoa hlokahala ho khetha mofuta o nepahetseng oa polymer le tekanyo bakeng sa metsi a litšila a fapaneng ho fihlela phello e ntle ka ho fetisisa ea kalafo. Ho phaella moo, lintlha tse kang boleng ba pH, mocheso, le lebelo la ho hlohlelletsa le tsona li tla ama katleho ea kalafo, 'me maemo a matle a hloka ho fumanoa ka liteko.
Li-polymer li bapala karolo ea bohlokoa e le li-flocculant kalafong ea metsi a litšila. Kutloisiso e tebileng ea mokhoa oa ts'ebetso le lintlha tse susumetsang tsa li-polymer li ka fana ka tšehetso ea bohlokoa ea khopolo-taba le tataiso e sebetsang bakeng sa ho ntlafatsa lits'ebetso tsa kalafo ea metsi a litšila le ho ntlafatsa katleho ea kalafo. Nakong e tlang, ka ntlafatso e tsoelang pele ea litlhoko tsa ts'ireletso ea tikoloho le tsoelo-pele e tsoelang pele ea saense le theknoloji, ho lumeloa hore ts'ebeliso ea li-polymer kalafong ea metsi a litšila e tla ba e pharaletseng le e tebileng haholoanyane.
