Moloko oa boraro oa defoamer ke silicone defoamer e thehiloeng ho polydimethylsiloxane (PDMS, dimethyl silicone oli).Hajoale, lipatlisiso le ts'ebeliso ea moloko ona oa li-defoamers li tsepame haholo Chaena.PDMS e entsoe ka ketane ea oksijene ea silicon le lihlopha tse ling tsa manyolo, 'me e ke ke ea hlophisoa ka thata holim'a filimi ea mokelikeli oa foam, e le hore li-bubble li tla phatloha.PDMS ea viscosity e tlase e na le thepa e ntle ea defoaming le viscosity e phahameng ea PDMS e na le thepa e ntle ea defoaming.
Melemo ea silicone defoamer
E na le inertia e ntle ea lik'hemik'hale 'me e thata ho sebetsana le lintho tse ling.E ka sebelisoa ka tharollo ea acid, alkali le letsoai.
Inertia e ntle ea 'mele, e ka sebelisoa indastering ea lijo le ea meriana,' me ha e na tšilafalo ea tikoloho.
E na le botsitso bo botle ba mocheso le ho fetoha ha maemo a tlaase, 'me e ka sebelisoa maemong a mangata a mocheso.
Viscosity e tlase 'me e ata ka potlako ho sebopeho sa khase-mokelikeli.
Khatello ea sefahleho e tlase ho 1.5-20 Mn / M (76 Mn / m bakeng sa metsi).
Ha ho bonolo ho qhibilihisoa ke surfactant tsamaisong ea ho foaming.
Tekanyo e tlase, viscosity e tlase le ho chesa ho tlase.
Mathata a silicone defoamer
1. Ho thata ho hasana tsamaisong ea metsi.
2. Hobane e qhibiliha ka har'a oli, phello ea ho senya tsamaiso ea oli e fokotsehile.
3. Ho hanyetsa mocheso o phahameng oa mocheso.
4. Ho hanyetsa ho fokolang ho alkalinity e matla.
Theko e phahameng:PDMS ke emulsion ea metsi ka oli (O/W) e entsoeng ka oli ea silicone, emulsifier, thickener, joalo-joalo, e entsoeng ka metsi.Khatello e holim'a metsi e fokotseha ka potlako mme e na le litlamorao tse matla tsa anti foaming le anti foaming.E batla e arotsoe ka mefuta e meraro: oli ea silicone, oli ea silicone + polyether e fetotsoeng le oli ea silicone e fetotsoeng ea polyether.
E tšoauoa ka:Khatello e tlase ea holim'a metsi, ts'ebetso e phahameng ea holim'a metsi le matla a matla a ho tlosa lefome.
Tekanyetso e nyane:E ka thibela le ho pshatla li-bubble bakeng sa mecha ea litaba e mengata ea bubble.E na le botsitso bo botle ba mocheso 'me e ka sebelisoa maemong a mangata a mocheso.E arolelanoa le polyether mme e na le phello ea synergistic.E sebelisoa haholo bakeng sa detergent, papermaking, pulp, tsoekere, electroplating, manyolo a lik'hemik'hale, li-additives, phekolo ea metsi a litšila le mekhoa e meng ea tlhahiso.Ka indasteri ea peterole, e sebelisoa haholo bakeng sa desulfurization ea khase ea tlhaho ho potlakisa karohano ea khase ea oli;E boetse e sebelisetsoa ho laola kapa ho hatella li-bubble ka lisebelisoa tse kang ethylene glycol drying, monko o monate oa hydrocarbon extract, asphalt process le lubricating oil dewaxing.Indastering ea masela, e sebelisoa bakeng sa ho tlosa lekoba ho daea, ho hloeka, ho etsa boholo le mekhoa e meng;E sebelisoa ts'ebetsong ea emulsion ea lik'hemik'hale le ho senya foaming indastering;E sebelisoa bakeng sa ho tlosa lefome lits'ebetsong tse fapaneng tsa mahloriso, ho belisoa le li-distillation indastering ea lijo.
