Defoaming ke bokhoni ba ho roala ho felisa foam e hlahisoang nakong ea tlhahiso le mokhoa oa ho roala.Li-defoamerske mofuta oa tlatsetso o sebelisetsoang ho fokotsa foam e hlahisoang nakong ea tlhahiso le / kapa ts'ebeliso ea liphahlo. Joale ke lintlha life tse amang ho tlosoa ha mabuba ha liaparo?

1. Ho tsitsipana ha sefahleho
Khatello e ka holimo ea ho roala e na le tšusumetso e kholo ho defoamer. Khatello e ka holimo ea defoamer e lokela ho ba tlase ho feta ea ho roala, ho seng joalo e ke ke ea khona ho senya le ho thibela foam. Khatello ea holim'a ho roala ke ntho e fapaneng, kahoo ha u khetha defoamer, ho lokela ho nahanoa ka tsitsipano e sa khaotseng ea holim'a metsi le ho fapana ha maemo a holim'a tsamaiso.

2. Lisebelisoa tse ling
Li-surfactants tse ngata tse sebelisoang ho roala ha li sebetsane le li-defoamers. Haholo-holo, li-emulsifiers, li-wetting le li-dispersing agents, li-agent tsa boemo bo holimo, li-thickeners, joalo-joalo li tla ama phello ea li-defoamers. Ka hona, ha re kopanya li-additives tse sa tšoaneng, re tlameha ho ela hloko kamano pakeng tsa li-additives tse fapaneng le ho khetha ntlha e ntle ea ho leka-lekanya.

3. Lintho tse folisang
Ha pente e kena ka mocheso o phahameng oa mocheso mocheso oa kamore, viscosity e tla theoha hang-hang 'me li-bubble li ka fallela holimo. Leha ho le joalo, ka lebaka la ho feto-fetoha ha mokelikeli, ho folisoa ha pente, le ho eketseha ha viscosity ea holim'a metsi, foam e penteng e tla ba e tsitsitseng haholoanyane, kahoo e qabeletsoe holim'a metsi, e leng se etsang hore ho be le masoba a honyehang le likoti. Ka hona, mocheso oa ho baka, lebelo la ho folisa, lebelo la ho qhibiliha ha solvent, joalo-joalo, le tsona li ama phello ea defoaming.

4. Lintho tse tiileng, viscosity, le elasticity ea liphahlo
Liaparo tse teteaneng tse tiileng haholo, tse nang le li-viscosity tse phahameng, le liphahlo tse phahameng tsa elasticity kaofela li thata haholo ho senya. Ho na le lintlha tse ngata tse sa thuseng ho senya, tse kang bothata ba li-defoamers ho hasana ka har'a liphahlo tsena, lebelo le liehang la li-microbubble tse fetohang li-macrobubbles, bokhoni bo fokotsehileng ba foam ho fallela holimo, le viscoelasticity e phahameng ea foam. Ho thata ho felisa foam ka liphahlo tsena, 'me ho bohlokoa ho khetha li-defoam le li-deaerator tse sebelisoang hammoho.

5. Mokhoa oa ho roala le mocheso oa kaho
Ho na le mekhoa e mengata ea kopo ea ho roala, ho kenyelletsa le borashe, ho roala li-roller, ho tšela, ho senya, ho fafatsa, khatiso ea skrine, joalo-joalo. Ho roala borokho le rolara ho hlahisa foam ho feta ho fafatsa le ho hohla. Ho phaella moo, tikoloho ea kaho e nang le mocheso o phahameng o hlahisa foam e ngata ho feta e nang le mocheso o tlaase, empa foam e boetse e bonolo ho e felisa ka mocheso o phahameng.
