【Ts'ebetso】2,4,7,9-Tetramethyl-5-decyne-4,7-diol Sehlahisoa sa surfactant ke tlatsetso e sebetsang e mengata e nang le thepa ea ho kolobisa, ea ho tlosa lekoeba le ho qhalakanya. Sehlahisoa ke symmetrical non-ionic surfactant. Sebopeho sa eona se ikhethang sa lik'hemik'hale sa gemini se nolofalletsa sehlahisoa ho fokotsa tsitsipano ea holim'a metsi, ho laola foam, le ho fokotsa kutloisiso ea metsi. E ka sebelisoa liindastering tse ngata: joalo ka liindasteri tse entsoeng ka metsi, pente ea lehong e thehiloeng metsing, pente ea polasetiki e thehiloeng metsing, enke e thehiloeng metsing, OPV, sekhomaretsi se se nang khatello ea maikutlo, tlhahiso ea mebala le dae, indasteri ea ho lokisa litšepe, flux. , chefo e bolaeang likokoanyana, joalo-joalo.
E falla ka potlako, e fokotsa tsitsipano e matla ea holim'a metsi le tsitsipano e tsitsitseng holim'a metsi, e senya le ho thibela foam, e na le kutloisiso e tlaase ea metsi, e ka kolobisa mefuta e sa tšoaneng ea li-substrates, ha e thehe li-micelles, e na le botsitso bo botle ba mocheso, 'me e na le botsitso bo botle ba acid-base. Lisebelisoa tse thehiloeng metsing li na le tsitsipano e phahameng ho feta li-solvents 'me li hloka ho eketsa li-surfactants ho ntlafatsa boemo ba metsi. Leha ho le joalo, lisebelisoa tsa setso tsa ho kolobisa li tla baka foam le foam e tsitsitseng. Haeba li-defoamers li eketsoa, mathata a fokolang a ho kolobisa joalo ka li-pinholes a tla hlaha hape.
E ka qoba mathata ana. Ts'ebetso e ntle haholo ho feta li-surfactants tsa setso, 'me e ka fana ka tsitsipano e tlase haholo le ho hatelloa ha foam tlasa maemo a matla.
Ka lebaka la sebopeho sa eona se ikhethang sa limolek'hule, li-surfactants tsa lintho tse tlotsang letoto la lintho ke sesebelisoa se setle sa symmetrical non-ionic defoaming.
The surfactant ha e na sebaka sa maru 'me e ka ba le thepa ea nako e telele ea defoaming ka mocheso o pharaletseng. Kutloelo-bohloko ea metsi Li-surfacts tse ngata li baka mathata a kutlo ea metsi sebakeng se koahetsoeng ka mor'a ho omisoa.
Li-surfactants tse phahameng haholo tsa hydrophilic tse kang anionic (dioctyl sulfosuccinate sodium salt) kapa polyethoxylated surfactants li qhibiliha habonolo ka metsing, tse bakang bofokoli holim'a seaparo se omisitsoeng, joalo ka ho khomarela, moriri o Mosoeu, moholi, le ho thibela metsi ho fokola.
Ho khothalletsoa ho eketsa emulsion kapa resin le li-surfactants tse ling pele, ebe u eketsa 2,4,7,9-Tetramethyl-5-decyne-4,7-diol series surfactants. -30 metsotso. Li-surfactants tse ling tsa 2,4,7,9-Tetramethyl-5-decyne-4,7-diol li ka khanya nakong ea lipalangoang kapa polokelo ka mocheso o tlase haholo; ho futhumatsa ha bonolo nakong ea ho hasana ho fokolang ho ka ba tsosolosa hantle.
E khothalelitsoeng boemo ba Keketso SEBELISA :
Ho roala ha metsi: 0.1% -3.0%

Lintlha tse ka holimo ke palo ea matla, 'me tekanyo e nepahetseng e khethoa ke letoto la liteko
Melemo:
Ho ata ka potlako, ho fokotsa tsitsipano e matla le e tsitsitseng holim'a metsi, ho senya le ho thibela metsi ho thibela metsi, ho noa metsi a tlaase, ho kolobisa substrates tse fapa-fapaneng ntle le ho etsa micelles. botsitso bo botle ba mocheso le ho hanyetsa acid-alkali.
Ho kolobisa:
Lisebelisoa tse thehiloeng metsing li na le tsitsipano e phahameng ho feta li-solvents, 'me hoa hlokahala hore ho eketsoe sehlaseli ho ntlafatsa boemo ba metsi. Lihlahisoa tsa letoto li ka hlola mathata ana, li fana ka ts'ebetso e phahameng ka ho fana ka tsitsipano e tlase ea holim'a metsi le ho thefuleha lehloeo le tlas'a maemo a matla.
Ho tlosa lekoba:
Letoto la li-surfactants, ka sebopeho sa tsona se ikhethileng sa limolek'hule, li sebetsa joalo ka li-symmetric non-ionic defoaming agents. Li bonts'a thepa e sa khaotseng ea ho tlosa lekoba holim'a mocheso o pharaletseng ntle le maru.
Sensitivity ea Metsi:
Li-surfactants tse ngata li baka mathata a kutloisiso ea metsi holim'a metsi a omisitsoeng. Li-surfactants tse phahameng haholo tsa hydrophilic joalo ka anionic (dioctyl sulfosuccinate) kapa li-surfactants tsa polyethoxylate li fetoha habonolo ka metsing, li baka bofokoli bo holim'a liphahlo tse omisitsoeng joalo ka ho khomarela le ho soeufala, atomization le ho se khonehe ha metsi.
