O le susu anionic hydroxyl o lo'o fa'aalia i lona fetaui lelei i le sui fa'auma ie, ma o le emulsion e matua mautu.Aemaise lava, o le tele o ausilali i lomitusi ie ma vali o le anionic.Afai e faʻaaogaina cationic hydroxy emulsion, e faigofie ona mafua ai le demulsification ma le suauʻu bleaching, aʻo emulsion anionic hydroxy e mafai ona aloese mai lenei faʻaletonu, o lea e sili atu ona lauiloa i tagata faʻaoga ma faʻaaogaina lautele.

3. emulsion suauu ionic hydroxyl silicone tuufaatasia

E ui lava o le cationic hydroxyapatite o se faʻamalulu ie sili ona lelei, o lenei emulsion e le faʻasaʻo i vai malo ma e le mafai ona faʻaaogaina i le dimethylolyl lua hydroxyurea urea resin.

E ui lava o le cationic hydroxyapatite o se faʻamalulu ie sili ona lelei, o lenei emulsion e le mafai ona faʻafefe i le vai malulu, ma e le mafai ona faʻaaogaina i le taele tutusa ma le dimethoxylated lua hydroxyvinyl urea resin (2D) resin, catalyst magnesium chloride ma le anionic sui sooupu.E le gata i lea, ona o le le lelei o le mautu o le emulsion, o polymers silicone e faigofie ona vavae ese mai le emulsion ma faʻafefe i luga o le vai, e masani ona taʻua o le "suauʻu bleaching".Afai o le cationic ma non-ionic emulsifiers e faʻaaogaina i le polymerization emulsion, e mafai ona faatoilaloina le faaletonu o le cationic emulsifier mo le saunia o le suauʻu suauʻu hydroxyl silicone.O le emulsion silicone saunia e mafai ona tatalia le vai malo, ma e mafai ona faʻaaogaina i totonu o le taele tutusa ma le 2D resin, magnesium chloride ma le paʻepaʻe VBL, ma e lelei le vevela ma le malulu.

4. non ionic hydroxyl silicone suauu emulsion

Ole susu ole vai e sili atu le fetuutuunai ma le mautu nai lo le susu hydroxy tu'ufua, o le tele o atunu'u ua faia taumafaiga tetele e su'esu'e le susu e le ninionic hydroxy.Mo se faʻataʻitaʻiga, UltrateX FSA, o se oloa fou na faia i Suitiselani, o se emulsion non-ionic ma le mamafa mole mole sili atu i le 200 afe ma le ulu hydroxyl o le lua methylsiloxane.O se laasaga i luma nai lo le Dc-1111 anionic hydroxyapatite emulsion i le Iunaite Setete.

5. Organosilicon faʻamaeʻaina sui ma isi vaega toaga

Ina ia faʻafetaui manaʻoga o le faʻamaeʻaina faʻamaeʻaina o ituaiga uma o ie, faʻaleleia le suauʻu faʻamaʻi, anti-static ma hydrophilic meatotino o ie faʻamaeʻaina silicone, ma faia ie filo vailaʻau e tele mea lelei o ie masani, tagata faigaluega silicone ua suʻesuʻeina le faʻaofiina o isi vaega malosi e pei o le vaega amino, vaega amide, vaega ester, vaega cyano, vaega carboxyl, vaega epoxy, ma isi. O le faʻaofiina o nei vaega e faia ai le organosilicon ie faʻamaeʻaina sui faʻapitoa faʻapitoa, mo se faʻataʻitaʻiga, o le faʻaofiina o le vaega amino i le mole o le organosilicon e fetaui lelei mo le fa'amae'a muamua ma le fa'amae'aina o fulufulu mamoe;o le faʻaofiina o le vaega amide e talafeagai mo le faʻamaeʻaina o le antifouling, ma o le a faʻaleleia atili le vaivai: o le faʻaofiina o le cyano vaega e lelei le faʻafefe o le suauu, ma o le anti-static aafiaga o le copolymer o le polyoxyethylene ether ma le organosilicon e lelei;o le organofluorine suia organosilicon ua i ai le suauu repellency.Anti filogia, anti-static, vai repellent ma le tele o isi tulaga lelei.

Lua.Silicone suauu emulsion defoamer.

Silicone suauu emulsion defoamer e masani lava suauu i le vai (O / W) emulsion, o lona uiga, vai o se vaega faifai pea, suauu silicone o se vaega discontinuous.E muamua fefiloi ma le suauu silicone, emulsifier ma thickening sui, ona faasolosolo malie lea ona faaopoopo vai e faafefiloi ai, faasolosolo olo i le colloid mill seia maua le emulsion manaomia.

Silicone suauu emulsion defoamer o se sui defoaming lautele faaaogaina i silicone defoamer.E mafai ona faʻaaogaina lautele e pei o le defoamer i le aqueous system.A faʻaaogaina, e mafai ona faʻapipiʻi saʻo le emulsion i le faiga faʻafefe, ma e mafai ona maua lelei le faʻaleagaina.Ina ia faʻaleleia le faʻaleagaina o le faʻafefe o le emulsion ma le saʻo o le fuaina, e masani lava e le faʻaaogaina saʻo nai lo le 10% o le suauʻu suauʻu silikono faʻapipiʻi: muamua, e faʻafefe i le 10% pe itiiti i le vai malulu pe tuusaʻo ma le fofo faʻafefe.O tapu e tatau ona faʻafefe i le vevela poʻo le faʻaitiitia o le vai, a leai o le a mafua ai le faʻaleagaina o le emulsion.O le mautu o le emulsion o le a sili atu ona leaga pe a uma ona faʻafefeteina, ma faʻapipiʻi (suauu bleaching) mea e mafai ona tupu i le teuina o le faagasologa, o lona uiga, demulsification.O le mea lea, e tatau ona faʻaaogaina le emulsion faʻafefeteina i se taimi vave e mafai ai.Afai e manaʻomia, e mafai ona faʻaopopo mea mafiafia e faʻaleleia ai le mautu o le emulsion.Mo le fa'agaioiga fa'atosina, e mafai ona fa'aopoopo le suau'u silicone emulsion a'o le'i fa'agasolo le faiga po'o fa'atasi.Mo le faʻagaioiga faʻaauau, e tatau ona faʻaopoopo le suauʻu silicone emulsion faʻaauau pe faʻalavelave i vaega talafeagai o le faiga.

I le faʻaaogaina o emulsion defoamers, o le vevela ma le gaʻo ma tulaga alkaline o le faiga faʻafefe e tatau ona amanaia.Ona o le suauʻu silicone emulsion e sili atu ona maaleale, o lona emulsion o le a demulsified muamua, ma o le a le lelei pe le aoga.Ole aofaiga ole suau'u silicone emulsion e masani lava 10 i 10Oppm o le mamafa o le vai foaming (e tusa ai ma le mita suauu silicone).Ioe, o loʻo i ai foi i lalo ifo o le 10 ppm ma sili atu nai lo le 100 ppm i mataupu faʻapitoa.Ole fua talafeagai e fa'atatau ile su'ega.

E masani lava, silicone suauu emulsion defoamer o le tele o suauu i le vai.E tusa ai ma ituaiga eseese o suauu silicone, silicone suauu emulsion defoamer ei ai ituaiga nei:

1. suau'u silicone emulsion fa'avae i luga ole suāu'u methyl silicone

O lenei ituaiga defoamer e faia i luga ole suauu dimethylsilicone, emulsifier ma vai.E mafai ona faʻaaogaina lautele i le faʻafefeteina, meaʻai, fai pepa, fiber, fale talavai, resini gaosia ma isi.

2. suau'u silicone emulsion fa'avae ile suau'u methyl ethoxy silicone

O lenei ituaiga defoamer e faia i le methyl ethoxy silicone suauu ma lona sui sooupu.

3. suau'u silicone emulsion fa'avae ile suau'u ethyl silicone

I tausaga talu ai nei, o le organosilicon defoamer o loʻo atinaʻe agai i le poloka copolymerization (poʻo le faʻapipiʻiina o le copolymerization) o le polyether organosilicon.O lenei ituaiga defoamer o loʻo i ai uiga o le organosilicon ma le polyether, o lea e faʻaleleia atili ai le malosi faʻafefe;organosilicon polyether copolymer defoamer, e lauiloa foi o le tagata emulsifying organosilicon defoamer, o se filifili ethylene oxide hydrophilic po o le ethylene oxide propylene oxide filifili poloka (po o le sulu) i le filifili mole mole organosilicon, ina ia tuufaatasia le vaega hydrophobic siloxane ma le polyether hydrophilic.I le avea ai o se mea faʻafefe, o sea mole e i ai se faʻasalalauga tele, e mafai ona faʻasalalau tutusa i totonu o le ala faʻafefe, ma e maualuga lona lelei.O se ituaiga fou o le fa'amama fa'alelei maualuga.O le emulsifying aafiaga o le tagata lava emulsifying silicone suauu e aunoa ma emulsifier e fai lava si faamalieina mo nisi faiga.E sili ona talafeagai mo i latou e le talafeagai mo le suauʻu suauʻu silicone lautele emulsion suauu silicone lautele.
