O a matou oloa autu: Amino silicone, poloka silikoni, hydrophilic silicone, o latou silicone emulsion uma, faʻafefeteina le faʻaleleia o le vai, faʻafefe vai (Fluorine free, Carbon 6, Carbon 8), vailaʻau fufuluina (ABS, Enzyme, Spandex protector, Manganese remover), Atunuʻu auina atu i fafo: Initia, Pakistan, Bangladesh, Türzbekye, ma isi.

 

Ole a'afiaga ole fa'amama ole surfactants o le uiga fa'avae lea e maua ai e surfactants le fa'aoga sili ona aoga. E aofia ai le olaga i aso uma o le faitau afe o aiga. Ma ua faʻateleina foʻi le faʻaaogaina i pisinisi eseese ma gaosiga faʻapisinisi.

Fa'amamago fa'amamago o se auala e fufulu ai i solu fa'aola, lea e fa'aogaina ai le solubility o solvents ma le solubility o surfactants e aveese ai le palapala mai luga o ie. O lona lelei o le mafai lea ona puipuia le faʻafefeteina o le fulufulu mamoe ma le siliki ie e mafua mai i le fufuluina, faʻapea foʻi ma le deformation ma le le lelei o lima lagona o lavalava.

 

O le palapala i luga o ie e mafai ona vaevaeina i ni ituaiga se tolu: suauu soluble, vai-soluble, ma le suauu ma le vai e le mafai ona solu.

E mafai ona aveese sa'o le palapala solu suau'u ma solu fa'aola. O solvents e mafai ona faʻaaogaina mo le fufuluina e masani lava o le suauʻu suauʻu mama, e masani ona aofia ai aliphatic hydrocarbons e pei ole 1,3-diethylcyclohexane, cycloaliphatic hydrocarbons, ma 1,2,4-trimethylphenylaromatic hydrocarbons. E le gata i lea, e iai foi carbon tetrachloride, trichlorethylene, tetrachloroethylene, ma isi.

Ina ia mafai ona aveese le palapala ma le solubility lelei o le vai poʻo le hydrophilicity malosi, e manaʻomia le faʻaopoopoina o sina vai ma surfactants i le faiga. O le fa'aopoopoina o mea fa'afefete e mafai ona taofia ai le toe tu'uina atu o le palapala malo i totonu o le solvent. O le fa'asalalauina mautu ma le taofia o le palapala i fa'asalalauga fa'aola e le toe fa'alagolago i le electrostatic repulsion i le va o vaega, ae e mafai ona fa'amoemoeina e le adsorption o surfactants i le feso'ota'iga solid-liquid.

Surfactants i fa'asalalauga fa'aola e fa'asusu i luga o mea malō e pei o kulupu polar, fa'atasi ai ma filifili lipophilic hydrocarbon e fa'atatau i le tulaga adsorption o solvents organic ma fa'apipi'i i luga ole feso'ota'iga malo-suavai. E mafai ona fausia ai se ata fofo o filifili kaponi hydrogen i luga o le palapala malo, fausia ai se pa malosi mo le faʻalavelave faʻafanua ma puipuia le faʻaputuina poʻo le toe tuʻuina o palapala i luga o le ie. O le i ai o sina vaega itiiti o le vai e mafai ona mafua ai le faʻamamaina o meaʻai ma luga ole ie, e faigofie ai mo i latou ona fegalegaleai ma vaega polar o surfactants, lea e aoga mo le adsorption o surfactants i luga o luga o le eleele (aemaise lava polar surfaces). E aoga lenei mea mo le faʻaleleia atili o le fufulu. E le gata i lea, pe a fausia e le surfactants ni micelles faʻasolosolo i solvents organic, o se vaega itiiti o le vai ma ona palapala e mafai ona solu i le vai e masani ona faʻamavaeina i totonu ole micelles i tua i le taimi e tasi.

 

Surfactants fa'aaogaina mo le fa'amamago e tatau ona ausia tulaga nei:

① E tatau ona mafai ona faʻamavaeina i le fufuluina o solvents ma faʻapipiʻi micelles, ma lava le malosi e faʻaopopo ai le vai solu E mafai ona faʻasalalau solo palapala malo ma maua ai le mautu faʻamalolo lelei i soʻo faʻalagona;
③ Fa'amama fa'amama i luga o tagamea ma fa'amama;
④ Leai se manogi, leai ni aʻafiaga leaga ile tagamea, leai se pala ile metala, ma isi.

Surfactants faʻaaogaina mo le faʻamama mamago e tatau ona faigofie ona solu ile faʻasalalauga faʻaola.

 

O fa'aoga masani e aofia ai:

① Anionic surfactants e pei ole petroleum sulfonate, sodium alkylbenzenesulfonate (poo amine salt), ma sodium succinate sulfonate;

② E le o ni ionic surfactants pei ole polyoxyethylene alkyl alcohol ethers, polyoxyethylene alkyl phenols, polyoxyethylene alkyl amides, ma isi.
