Antifoam ke eng ho hloekisa metsi a litšila?

Antifoam, eo hape e tsejoang e le defoamer, ke motsoako oa lik'hemik'hale o sebelisoang mekhoeng ea ho hloekisa metsi a litšila ho laola ho thehoa ha foam.Foam ke taba e atileng litsing tsa ho hloekisa metsi a litšila 'me e ka hlaha mehloling e fapaneng joalo ka lintho tse phelang, li-surfactants, kapa pherekano ea metsi.Le hoja foam e ka 'na ea bonahala e se kotsi, e hlile e ka sitisa ts'ebetso ea ts'ebetso ea metsi a litšila ka ho kena-kenana le ts'ebetso ea lisebelisoa, ho fokotsa katleho ea phekolo ea lik'hemik'hale, le ho baka mathata a mangata kapa a mangata.

Li-antifoam li sebetsa ka ho senya li-bubble tsa foam, li etsa hore li oe kapa li kopane, kahoo li fokotsa molumo oa foam le ho li thibela ho kena-kenana le mekhoa ea phekolo.Lisebelisoa tsena hangata li na le motsoako oa li-surfactants, oli, silicones, kapa lintho tse ling tsa hydrophobic.Ha e kenngoa metsing a litšila, li-antifoam agents li fallela holim'a foam 'me li senya tsitsipano ea holim'a metsi, e lebisang ho phatloheng ha li-bubble tsa foam.

Ho na le mefuta e 'maloa ea li-antifoam tse sebelisoang ho hloekisa metsi a litšila, e' ngoe le e 'ngoe e na le thepa ea eona le lits'ebetso tse ikhethileng:

Li-antifoam tse thehiloeng ho silicone:

Tsena ke tse ling tsa li-antifoam tse sebelisoang ka ho fetisisa ka lebaka la katleho ea tsona ho pholletsa le maemo a mangata.Li-antifoam tse thehiloeng ho silicone li tsitsitse, ha li na metsi, 'me li ka etsoa hore li lumellane le mekhoa e fapaneng ea ho hloekisa metsi a litšila.

Melemo ea li-organosilicon defoamers:

Ho se sebetse hantle ha lik'hemik'hale, ho sa sebetsane le lintho tse ling, ho ka sebelisoa lits'ebetsong tsa asiti, alkaline le letsoai.

Boiketlo bo botle ba 'mele, bo loketseng ho sebelisoa indastering ea lijo le ea meriana, ntle le tšilafalo tikolohong.

Botsitso bo itekanetseng ba mocheso, ho feto-fetoha ha maemo a tlaase, 'me e ka sebelisoa ho feta mocheso o pharaletseng

Viscosity e tlase, e ata ka potlako sehokelong sa mokelikeli oa khase

Khatello ea metsi e tlase ho 1.5-20 mN/m (metsi ke 76 mN/m)

Ha e qhibilihe ka har'a li-surfactants tsa sistimi e foaming

Tekanyo e tlase, viscosity e tlase, le ho chesa ho tlase

Li-antifoam tsa polymeric:

Lisebelisoa tsena tsa antifoam li thehiloe holim'a li-polymers tse sitisang ho thehoa ha foam ka ho bapatsa holim'a li-bubble tsa foam le ho fetola botsitso ba tsona.Hangata li-antifoam tsa polymeric li sebelisoa maemong ao li-antifoam tse tloaelehileng li ka 'nang tsa se ke tsa sebetsa hantle, joalo ka maemong a metsi a litšila a nang le alkaline haholo kapa a acidic.

Li-antifoam tse ling:

Maemong a mang, li-antifoam tse thehiloeng ho silicone li ka 'na tsa se ke tsa tšoaneleha ka lebaka la mathata a theknoloji kapa litlhoko tse itseng tsa tshebetso.Li-antifoam tse se nang silicone, tse kang li-antifoam tse thehiloeng ho oli ea diminerale kapa tse nang le mafura a mafura, li fana ka mekhoa e meng e ka 'nang ea e-ba e sa silafatseng tikoloho kapa e loketseng ho feta lits'ebetsong tse itseng.

Li-antifoam tse phofshoana:

Li-antifoam tse ling li fumaneha ka mokhoa oa phofshoana, tse ka ba molemo lits'ebetsong moo li-additives tsa metsi li sa sebetseng kapa moo mosebetsi oa nako e telele oa antifoam o hlokahalang.

Khetho ea moemeli ea loketseng oa antifoam e itšetlehile ka lintlha tse kang mofuta oa metsi a litšila, mokhoa o khethehileng oa phekolo o sebelisoang, litlhoko tsa taolo, le ho nahanela litšenyehelo.Ntle le ho khetha moemeli ea nepahetseng oa antifoam, litekanyetso tse nepahetseng le mekhoa ea ts'ebeliso li bohlokoa ho netefatsa taolo e sebetsang ea foam ntle le ho ama hampe ts'ebetso ea kalafo ea metsi a litšila.

Le hoja li-antifoam li sebetsa hantle ho laola foam mekhoeng ea ho hloekisa metsi a litšila, ke habohlokoa ho li sebelisa ka bohlale ho qoba liphello tse sa lebelloang tse kang ho kena-kenana le mekhoa ea phekolo ea likokoana-hloko kapa ho lokolloa ha lintho tse kotsi tikolohong.Ho lekola khafetsa maemo a foam le ho lokisoa ha litekanyetso tsa antifoam ha ho hlokahala ho ka thusa ho ntlafatsa taolo ea foam ha ho ntse ho fokotsa litlamorao life kapa life tse mpe mabapi le katleho ea kalafo ea metsi a litšila le ho latela tikoloho.
