Li-defoamersli bohlokoa lits'ebetsong tsa indasteri. Mekhoa e mengata ea indasteri e hlahisa foam, ebang ke ho ferekanngoa ha mechine kapa lik'hemik'hale. Haeba e sa laoloe le ho phekoloa, e ka baka mathata a tebileng.
Foam e thehoa ka lebaka la ho ba teng ha lik'hemik'hale tsa surfactant tsamaisong ea metsi, e leng ho tsitsisa li-bubble, ho fella ka ho thehoa ha foam. Mosebetsi oa li-defoamers ke ho nkela lik'hemik'hale tsena sebaka sa surfactant, e leng se etsang hore lipululana li phatlohe le ho fokotsa lekoeba.
Mefuta e ka sehloohong ea foam ke efe?
Biofoam le surfactant foam:
Biofoam e hlahisoa ke likokoana-hloko ha li senya le ho senya lintho tse phelang metsing a litšila. Biofoam e na le lipululana tse chitja tse nyane haholo, e tsitsitse haholo, 'me e shebahala e omme.
Foam e hloekisitsoeng e bakoa ke ho eketsoa ha li-surfactants tse kang sesepa le li-detergents, kapa ke karabelo ea li-corrosives ka oli kapa mafura le lik'hemik'hale tse ling.
Li-defoam li sebetsa joang?
Li-defoams li thibela ho thehoa ha foam ka ho fetola thepa ea mokelikeli. Li-defoamers li nka sebaka sa limolek'hule tsa surfactant karolong e tšesaane ea foam, e leng se bolelang hore monolayer ha e khone ho reketla 'me ho ka etsahala hore e robehe.
Tsela ea ho khetha defoamer?
Li-defoam ka kakaretso li arotsoe ka li-defoamers tse thehiloeng ho silicone le li-non-silicone-based defoamers. Khetho ea defoamer e itšetlehile ka litlhoko le maemo a kopo e khethehileng. Li-defoam tse entsoeng ka silicone li sebetsa hantle tlas'a mefuta e mengata ea pH le maemo a mocheso 'me ka kakaretso li ratoa bakeng sa botsitso le katleho ea tsona. Li-defoam tse se nang li-silicone ke li-defoam tse thehiloeng haholo-holo ho metsoako ea lintho tse phelang tse kang li-amide tse mafura, sesepa sa tšepe, lino tse tahang tse mafura le li-ester tse mafura a acid. Melemo ea litsamaiso tse seng tsa silicone ke li-coefficients tse kholo tsa diffusion le bokhoni bo matla ba ho senya foam; phoso e kholo ke hore bokhoni ba ho hatella foam bo fokola hanyane ka lebaka la tsitsipano e phahameng ho feta silicone.
Ha u khetha defoamer e nepahetseng, lintlha tse kang mofuta oa sistimi, maemo a ts'ebetso (mocheso, pH, khatello), tšebelisano ea lik'hemik'hale, le litlhoko tsa taolo li hloka ho nahanoa. Ka ho khetha defoamer e nepahetseng, indasteri e ka sebetsana ka katleho le mathata a amanang le foam le ho ntlafatsa katleho ea ts'ebetso ka kakaretso.
Ke neng ha ho hlokahala setlolo sa defoaming ho hloekisa metsi?
Nakong ea ho hloekisoa ha metsi, hangata ho na le maemo a etsang hore motho a phophome, a kang ho ferekana ha metsi, ho ntšoa ha likhase tse qhibilihileng, le boteng ba lintho tse hloekisang le lik’hemik’hale tse ling.
Lits'ebetsong tsa kalafo ea metsi a litšila, foam e ka koala lisebelisoa, ea fokotsa ts'ebetso ea ts'ebetso ea kalafo, mme ea ama boleng ba metsi a hloekisitsoeng. Ho eketsa li-defoam ho metsi ho ka fokotsa kapa ho thibela ho thehoa ha foam, e leng ho thusang ho boloka mokhoa oa phekolo o sebetsa hantle le ho ntlafatsa boleng ba metsi a hloekisitsoeng.
Li-defoam kapa li-antifoam ke lihlahisoa tsa lik'hemik'hale tse laolang 'me, ha ho hlokahala, li tlosa foam metsing a hloekisitsoeng ho qoba liphello tse mpe tsa ho phophoma ka mekhahlelo e sa rateheng kapa ho feta tekano.
