O le fa'aupuga lona tolu o le fa'ameamea o se fa'amea fa'asala silicone e fa'avae i luga ole polydimethylsiloxane (PDMS, dimethyl silicone oil).I le taimi nei, o le suʻesuʻega ma le faʻaogaina o lenei augatupulaga o defoamers o loʻo faʻapitoa i Saina.O le PDMS e aofia ai le filifili okesene silikoni ma isi vaega faʻaletino, ma e le mafai ona faʻapipiʻi faʻapipiʻi i luga o le ata vai vai, ina ia paʻu le pulu.O le PDMS viscosity maualalo o lo'o i ai mea lelei e fa'afefe ai le fo'i ma maualuga ole PDMS o lo'o iai mea lelei e fa'afua.
Tulaga lelei ole silicone defoamer
E iai le inertia kemikolo lelei ma e faigata ona tali atu i isi mea.E mafai ona faʻaaogaina i vaifofo acid, alkali ma masima.
Lelei physiological inertia, e mafai ona faʻaaogaina i meaʻai ma falemaʻi falemaʻi, ma e leai se faʻaleagaina i le siosiomaga.
E lelei le mautu vevela ma le maualalo volatility, ma e mafai ona faʻaaogaina i le lautele o le vevela.
O le viscosity e maualalo ma sosolo vave i le faʻaogaina o le kesi-suavai.
Tete'e o luga e la'ititi ifo ile 1.5-20 Mn/M (76 Mn/m mo vai).
E le faigofie ona solubilized e surfactant i le faiga fa'afu.
Ole fua maualalo, maualalo ole viscosity ma maualalo le mu.
Le lelei ole silicone defoamer
1. E faigata ona taape i le vai.
2. Ona e soluble i le suauu, o le aafiaga defoaming i le faiga suauu ua faaitiitia.
3. Le lelei le maualuga o le vevela.
4. Le lelei le tetee i le malosi alkalinity.
Tau maualuga:PDMS o se vai i totonu o le suauʻu (O / W) emulsion faia i le gaʻo silicone, emulsifier, mafiafia, ma isi, lea e emulsified e le vai.E vave ona fa'aitiitia le tete'e o luga ma e malosi le fa'a'ele'ele o le fa'afu'a ma le fa'a'afi fa'a.O lo'o fa'atusa ona vaevaeina i ni fa'avae se tolu: suau'u silicone, suau'u silicone + polyether suiga ma suau'u suau'u suau'u polyether.
O loʻo faʻaalia e:Maualalo i luga tete'e, maualuga galuega i luga ma malosi defoaming mana.
Fa'aitiitia fua:E mafai ona fa'alavelave ma talepe pupuni mo le tele o fa'asalalauga fa'asalalau.E lelei le mautu vevela ma e mafai ona faʻaaogaina i le lautele o le vevela.E fa'asoa fa'atasi ma polyether ma e iai sona aafiaga fa'atasi.E faʻaaogaina lautele mo le faʻafefeteina i le faʻamama, pepa, pulupulu, suka, eletise, vailaʻau vailaʻau, mea faʻapipiʻi, togafitiga vai otaota ma isi gaioiga gaosiga.I totonu o le alamanuia suauʻu, e faʻaaogaina lautele mo le desulfurization o le kasa masani e faʻavavevave ai le vavaeeseina o le suauu-kasa;E fa'aogaina fo'i e fa'atonutonu pe fa'amama fa'afu i masini e pei ole fa'amago ole ethylene glycol, fa'amagoina o le hydrocarbon aromatic, fa'aogaina ole asphalt ma le lubricating oil dewaxing.I fale gaosi oloa, e faʻaaogaina mo le faʻafefe i le valiina, sasaina, sizing ma isi faiga;E faʻaaogaina i le faʻagasologa o vailaʻau emulsion ma defoaming i alamanuia;E faʻaaogaina mo le faʻafefe i le tele o faʻatonuga, faʻafefeteina ma faʻamaʻi faʻagasologa i totonu o pisinisi taumafa.
