Li-flocculant tse tloaelehileng tsa cationic ke life?

Kalafo ea metsi ke karolo ea bohlokoa ea tsamaiso ea tikoloho, ho netefatsa hore metsi a bolokehile bakeng sa tšebeliso le tšebeliso ea indasteri. E 'ngoe ea lintlha tsa bohlokoa ts'ebetsong ena ke tšebeliso ea li-flocculant—lik'hemik'hale tse khothalletsang ho bokellana ha likaroloana tse emisitsoeng ka lihlopha tse kholo, kapa li-floc, tse ka tlosoang habonolo metsing. Har'a mefuta e fapaneng ea li-flocculant, li-flocculant tsa cationic li sebetsa hantle haholo ka lebaka la chaja ea tsona e ntle, e sebelisanang haholo le likaroloana tse nang le chaja e mpe tse atisang ho fumanoa metsing a litšila. Sengoloa sena se hlahloba li-flocculant tse tloaelehileng haholo tsa cationic tse sebelisoang kalafong ea metsi le ts'ebeliso ea tsona.

Li-Polyacrylamides tsa Cationic(CPAM)

Li-Polyacrylamides tsa Cationic, ke tse ling tsa li-flocculant tse sebelisoang haholo indastering ea kalafo ea metsi. Bakeng sa basebelisi ba bangata, CPAM ke khetho ea bona e betere. Li-polymer tsena li na le li-subunit tsa acrylamide, tse ka etselitsoeng ho kenyelletsa lihlopha tse sebetsang tsa cationic. Ho tenyetseha ha li-polyacrylamides tsa Cationic ho itšetlehile ka boima ba tsona ba limolek'hule le bongata ba tjhaja, e leng se li lumellang ho etsoa hore li sebelisoe ka mokhoa o ikhethileng. Li-C-PAM li sebetsa hantle haholo ho phekoleng metsi a litšila a indasteri le ho tlosoa ha metsi a litšila ka lebaka la bokhoni ba tsona bo phahameng ba ho qhaqha le litlhoko tse tlase tsa tekanyo.

Poly(diallyldimethylammonium chloride) (PolyDADMAC)

PolyDADMAC ke flocculant e sebelisoang haholo ea cationic e tsejoang ka ho ba le tjhaja e ngata le bokgabane ba eona lits'ebetsong tsa kalafo ea metsi. Polymer ena e sebetsa haholo lits'ebetsong tsa ho kopanya le ho kopanya, e leng se etsang hore e be khetho e tsebahalang bakeng sa ho phekola metsi a nooang, metsi a litšila le litšila tsa indasteri. PolyDADMAC e sebetsa hantle hammoho le li-flocculant tse ling le li-coagulant, e ntlafatsa ts'ebetso ea kalafo ka kakaretso ka ho fana ka mokhoa o tiileng oa ho kopanya le ho tlosa likaroloana.

Li-polyamine(PA)

Li-polyamine ke sehlopha se seng sa li-flocculant tsa cationic tse sebelisoang haholo kalafong ea metsi. Metsoako ena, e kenyeletsang poly(dimethylamine-co-epichlorohydrin) le meaho e ts'oanang, e bonts'a bongata bo matla ba charge ea cationic, e leng se etsang hore e sebetse hantle haholo ho fokotseng likaroloana tse nang le charge e mpe. Li-polyamine li thusa haholo ho hlakiseng metsi a tala, ho tlosa lintho tse phelang, le ho phekola litšila tse fapaneng tsa indasteri. Bokhoni ba tsona ba ho theha li-floc tse teteaneng bo fella ka linako tse potlakileng tsa ho lula le ho hlaka ho ntlafetseng ha metsi a phekotsoeng.

Likopo le Melemo

Di-flocculant tsa cationic li bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa kalafo ea metsi, ho tloha ho metsi a litšila a masepala le tlhoekiso ea metsi a nooang ho ea ho taolo ea lithōle tsa indasteri. Molemo oa tsona o ka sehloohong o ho bokhoni ba tsona ba ho fokotsa likaroloana tse nang le tjhaja e mpe ka katleho, e leng se lebisang ho thehoeng ha floc ka potlako le ka katleho. Sena se fella ka ho hlaka ho ntlafetseng, ho fokotseha ha seretse, le ho ntlafatsa boleng ba metsi ka kakaretso. Ho feta moo, li-flocculant tsa cationic hangata li sebelisoa hammoho le lik'hemik'hale tse ling tsa kalafo, tse kang li-coagulant, ho ntlafatsa ts'ebetso ea kalafo le ho fihlela maemo a lakatsehang a boleng ba metsi.

Tšebeliso ea li-flocculant tsa cationic ke ea bohlokoa lits'ebetsong tsa sejoale-joale tsa kalafo ea metsi, e fana ka litharollo tse sebetsang hantle le tse tšepahalang bakeng sa ho bokella le ho tlosa likaroloana. Li-polyacrylamides, li-polyamine, PolyDADMAC li emela tse ling tsa li-flocculant tsa cationic tse tloaelehileng le tse sebetsang tse fumanehang kajeno. Ho tenyetseha ha tsona, bokhoni ba tsona le ho ikamahanya le maemo li etsa hore e be lisebelisoa tsa bohlokoa ho netefatsa hore ho na le metsi a hloekileng le a sireletsehileng bakeng sa ts'ebeliso e fapaneng.

Ehlile, khetho ea flocculant e boetse e itšetlehile ka mekhoa ea tšebeliso ea mosebelisi, sebopeho sa thepa, tikoloho, jj. Tataiso ea tšebeliso ea sehlahisoa e lokela ho lateloa.
