Li-defoamerli bohlokoa lits'ebetsong tsa indasteri. Mekhoa e mengata ea indasteri e hlahisa foam, ebang ke ho sisinyeha ha mechine kapa karabelo ea lik'hemik'hale. Haeba e sa laoloe le ho phekoloa, e ka baka mathata a tebileng.
Foam e thehoa ka lebaka la boteng ba lik'hemik'hale tsa surfactant tsamaisong ea metsi, tse tsitsisang lipululana, e leng se fellang ka ho thehoa ha foam. Karolo ea li-defoamer ke ho nkela lik'hemik'hale tsena tsa surfactant sebaka, e leng se etsang hore lipululana li phatlohe le ho fokotsa foam.
Mefuta e meholo ea foam ke efe?
Foam ea Biofoam le ea surfactant:
Biofoam e hlahisoa ke likokoana-hloko ha li fetola le ho bolisa lintho tse phelang metsing a litšila. Biofoam e entsoe ka lipululana tse nyenyane haholo tse chitja, e tsitsitse haholo, 'me e shebahala e omme.
Foam ea surfactant e bakoa ke ho eketsoa ha li-surfactant tse kang sesepa le sesepa, kapa ke karabelo ea lintho tse senyang ka oli kapa mafura le lik'hemik'hale tse ling.
Li-defoamers li sebetsa joang?
Li-defoamer li thibela ho thehoa ha foam ka ho fetola litšobotsi tsa mokelikeli. Li-defoamer li nkela limolek'hule tsa surfactant lera le lesesaane la foam sebaka, ho bolelang hore lera le le leng ha le tenyetsehe haholo 'me ho ka etsahala hore le robehe.
Mokhoa oa ho khetha defoamer?
Hangata li-defoamer li arotsoe ka li-defoamer tse thehiloeng ho silicone le li-defoamer tse seng tsa silicone. Khetho ea li-defoamer e itšetlehile ka litlhoko le maemo a ts'ebeliso e itseng. Li-defoamer tse thehiloeng ho silicone li sebetsa hantle tlas'a maemo a fapaneng a pH le mocheso 'me hangata li ratoa ka lebaka la botsitso le katleho ea tsona. Li-defoamer tse seng tsa silicone ke li-defoamer tse thehiloeng haholo-holo metsoakong ea lintho tse phelang tse kang li-amides tse mafura, sesepa sa tšepe, lino tse tahang tse mafura le li-ester tsa asiti e mafura. Melemo ea litsamaiso tse seng tsa silicone ke li-coefficients tse kholo tsa ho hasana le bokhoni bo matla ba ho roba foam; bothata bo boholo ke hore bokhoni ba ho thibela foam bo fokola hanyane ka lebaka la khatello e phahameng ea bokaholimo ho feta silicone.
Ha ho kgethwa defoamer e nepahetseng, dintlha tse kang mofuta wa sistimi, maemo a tshebetso (mocheso, pH, kgatello), ho tsamaellana ha dikhemikhale, le ditlhoko tsa taolo di hloka ho nahanelwa. Ka ho kgetha defoamer e nepahetseng, indasteri e ka laola mathata a amanang le foam ka katleho le ho ntlafatsa bokgoni ba tshebetso ka kakaretso.
Ke neng moo ho hlokahalang ho eketsa defoaming kalafong ea metsi?
Nakong ea phekolo ea metsi, hangata ho ba le maemo a etsang hore ho be le pululo, joalo ka ho fuluoa ha metsi, ho lokolloa ha likhase tse qhibilihisitsoeng, le boteng ba sesepa le lik'hemik'hale tse ling.
Litsamaisong tsa kalafo ea metsi a litšila, foam e ka koala lisebelisoa, ea fokotsa katleho ea ts'ebetso ea kalafo, 'me ea ama boleng ba metsi a hloekisitsoeng. Ho eketsa li-defoamer metsing ho ka fokotsa kapa ha thibela ho thehoa ha foam, e leng se thusang ho boloka ts'ebetso ea kalafo e sebetsa hantle le ho ntlafatsa boleng ba metsi a hloekisitsoeng.
Li-defoamer kapa li-antifoam agent ke lihlahisoa tsa lik'hemik'hale tse laolang le, haeba ho hlokahala, ho tlosa foam metsing a hloekisitsoeng ho qoba litlamorao tse mpe tsa ho foam maemong a sa batleheng kapa ho feta tekano.
