O le vaiaso talu ai, na matou talanoa ai e uiga i nisi o mea e faʻavae i le suauʻu ma mea paʻu i mea faʻapipiʻi matrix. I aso nei, o le a matou faʻaauau pea ona faʻamatalaina mea o loʻo totoe matrix: mea faʻagogo ma mea faʻafefe.
Colloidal raw material – leoleo o le viscosity ma le mautu
Glial mea mata'ina o vai-soluble polymer compounds. Ole tele o nei mea e mafai ona fa'alautele ile colloid ile vai e fai ai le pauta malo ma fa'apipi'i. E mafai foʻi ona faʻaaogaina e fai ma emulsifiers e faʻamautu ai emulsions poʻo faʻamalolo. E le gata i lea, e mafai foi ona latou faia ata tifaga ma mafiafia gel. O le glial raw meafaitino o loʻo faʻaaogaina i mea teuteu e masani ona vaevaeina i ni vaega se tolu: natura ma synthetic, ma semi synthetic.
Fua fa'apolopolo fa'alenatura e mafai ona solu i le vai: e masani lava ona maua mai i la'au po'o manu, e pei o le masoa, pulu laau (pei o le Arabic gum), gelatin manu, ma isi mea. O le lelei o nei mea fa'alenatura e maua mai le pulu e ono le mautu ona o suiga o le tau ma si'osi'omaga fa'afanua, ma e iai le lamatiaga o le fa'aleagaina e siama po'o le li'o.
Fa'apipi'i polymer vai fa'afefeteina, e aofia ai le polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic acid, ma isi mea, o lo'o i ai meatotino mautu, pa'u maualalo le pa'u, ma tau maualalo, ma fa'apea ona suitulaga i le vai-soluble polymer compounds e avea ma punavai autu o mea colloidal. E masani ona faʻaaogaina e avea o se mea faʻapipiʻi, mafiafia, faʻapipiʻi ata, ma faʻamautu emulsifying i mea teuteu.
Semi synthetic vai-soluble polymer compounds: O mea sili ona taatele e aofia ai le methyl cellulose, ethyl cellulose, carboxymethyl cellulose sodium hydroxyethyl cellulose, guar gum ma ona mea e maua mai ai, ma isi.
Solvent mea mata - ki i le faʻamavaeina ma le mautu
Solvent mea mata o mea taua ia i le tele o vai, pa'u, ma fa'apipi'i fa'atatau ile tausiga o pa'u. Pe a tuʻufaʻatasia ma isi mea faʻapitoa i le fua faʻatatau, latou te tausia ni mea faʻapitoa faaletino o le oloa. O mea e masani ona faʻaaogaina faʻafefe i mea teuteu e masani ona aofia ai le vai, ethanol, isopropanol, n-butanol, ethyl acetate, ma isi. O le vai e masani ona faʻaaogaina i mea tau paʻu.
