O le atinaʻe tulaga o meaola faʻaletino defoamers i le pepa alamanuia. O le suʻesuʻega o suʻesuʻega a le au sooupu ola i le lalolagi o loʻo suia mai le tasi ituaiga eseese vaega i le tuʻufaʻatasiga ituaiga. Atunuʻu i le salafa o le lalolagi ua tuʻuina atu se tele aofaʻi o tagata faigaluega puleaina ma faʻaputugatupe i le tuʻufaʻatasia faʻapitoa polofesa o meaola defoamers. Faʻatasi ai ma tupe teu faʻafaigaluega ma aseta, tele paionia iʻuga ua ausia, ma le maeʻa lelei aoga o meaola defoamers ua matua faʻaleleia atili. O le polofesa o sauniuniga meaola ma lona faʻaaogaina faʻaalia ai se loloto atinae aga. I le avea ai o se taua vaega o le ola aiga, Organic defoamers maua le tutusa atinaʻe aga i le pepa pisinisi.

E pei ona tatou iloa uma, i le maualuga-lelei pepa alamanuia sui o le oleic acid amide, polyeter, ma mea totoina, ua faʻaleagaina defoamers ua suia atoa tu ma aga le lelei ituaiga o minerale suauʻu, fualaʻau suauʻu, ava malosi, ma isi, ma sa faia tele saofaga i le galuega pepa. I se tulaga lautele, o polyther silicone defoamers e liua mai le tele o amataga. Silicone defoamers mafai ona faʻaaogaina e avea ma faʻavae mo le faʻavasegaina polyhere silicone defoamers. E tusa ai ma a latou eseʻesega, e mafai ona vaeluaina poletone siloolo i totonu o le polyol ituaiga ma le fatty acid ester type, o lona uiga, amine ether type. O nei ituaiga o defoamers ei ai a latou lava uiga.

O le auiliiliga vailaʻau faʻavae e ese mai isi Organic defoamers. E le faʻapitoa vaega e tutusa ma leai-optically toaga, ma e leai se fesoʻotaʻiga ma tuʻufaʻatasiga o loʻo aofia ai vai, vaega hydrocarbon poʻo optically toaaga vaega. Faʻatusatusa i isi Organic silicon defoamers, e mafai demulsify. Maelega, e masani lava na ona manaʻomia e faʻaopopo le vaega tele o molar o le 1×10-6 ~ 75×10-6 faʻatautaia e le faiga ia maua ai le faʻamoemoe aoga o le maualuga-lelei demulsification.

O meatotino tino e malleable i lautele tuufaatasiga, ma e le faigofie ona i ai exothermic tali ma foam tuufaatasiga. Organic defoamers e lelei le teteʻe o le vevela ma teteʻe ile maualuga ma maualalo le vevela o suʻega. O le viscosity o le methyl silicone oil e faʻasolosolo ona tulaʻi mai i le 200°C, ma le silicon-oxygen bond e le faʻavaivaia. O le methyl silicone suauʻu e sili ona fetuʻunaʻi ma faila. O le mea lea, o le silo defoamer e aoga e faʻaleleia le tulaga lelei o le pepa coated.

Organic defoamers e saogalemu, lanumeamata gaosi, ma physiologically faʻalauteleina. O lenei mea o loʻo aoga ma atamai e gaosia. Organic defoamers i ai le teteʻe i le matua, faʻagasologa o galuega ma mea e faʻasaga i le soifua matua. E mafai ona faʻaaogaina uma i lalo o tulaga faʻafanua o le siosiomaga. Organic defoamers have high O le aotelega o faatinoga o le tulaga lelei, ae o le tau tuusao e sili atu. E mafai ona faʻaaogaina i gaioiga uma e gaosia i le pepa alamanuia, ma maualuga demulsification lelei ma o nisi taimi le faʻamalieina foam taofi aafiaga.

O le mea lea, o le organic defoamer mafai ona tuʻufaʻatasia ma isi surfactants pei o oleic acid amide ma polyether ma demulsification ma foam suppression faʻapitoa e fausia ai se tuʻufaʻatasi meaola defoamer, lea e le gata mafai faʻaleleia ai le tomai faapitoa taofiofia malosi gafatia o le organic defoamer, ae faʻapena foi Faʻaitiitia le tau tuusao o oloa. Faatasi ai ma le tomai faapitoa atinae o surfactant compounding, faatulagaina defoamers maua lautele talosaga maketi ono ma tele maketi ono.
