Hydroxyethyl cellulose (HEC) ma le hydroxypropyl methyl cellulose (HPMC) o mea ia e lua e masani ona faʻaaogaina mafiafia.O vaega ia o mea faʻapipiʻi faʻapipiʻi e mafai ona faʻaogaina e tuʻuina atu ai le teteʻe, faʻateleina le viscosity, poʻo le tuʻuina atu o le ductility.E tutusa a latou vailaʻau, ae o loʻo i ai ni eseesega manino.
O le HEC o le ethylene-acetate analogue e aofia ai le formaldehyde, methanol ma le sodium hydroxide.E maualuga le thixotropic ma e mafai ona faʻaaogaina e fai ma lubricants, mea faʻapipiʻi togafitiga ma faʻapipiʻi mo mea eletise ma fale gaosi oloa.E mafai fo'i ona fa'aoga Hecs e fai ma mea mafiafia, fa'asalalauina ma fa'ainitaneti fua.
O le HPMC o le isi ethylene-acetate analogue, e aofia ai le methanol, sodium hydroxide, ma le carbonate.E maualuga le viscosity, elasticity ma expansibility, e mafai ona faʻaaogaina e pei o faʻapipiʻi, vali, faʻamamaina ma vaitusi faʻaopoopoga.E le gata i lea, e mafai foi ona faʻaaogaina mo sauniuniga tioata ma o loʻo i ai le mautu o le faiga lamolemole.
Hydroxyethyl cellulose HEC, e pei o se non-ionic surfactant, o loʻo i ai mea nei e faʻaopoopo i le mafiafia, faʻamalolo, faʻapipiʻi, faʻafefe, faʻavae ata, faʻasalalau, taofi vai ma puipuiga colloidal aafiaga:
1, hydroxyethyl cellulose HEC e mafai ona faʻamavaeina i le vevela poʻo le vai malulu, maualuga le vevela poʻo le faʻafefeteina e le faʻafefe, ina ia i ai le tele o le solubility ma uiga viscosity, ma mea e le o le gel vevela;
2, hydroxyethyl cellulose HEC lava ituaiga e le o ni ionic e mafai ona ola faatasi ma le tele o isi polymers vai-soluble, surfactants, masima, o se ituaiga o colloidal mafiafia o loʻo i ai vaifofo maualuga electrolyte;
3, hydroxyethyl cellulose HEC vai e mafai ona fa'aluaina maualuga atu nai lo le methyl cellulose, fa'atasi ai ma tulafono faatonutonu tafe;
4. O le faʻasalalauina gafatia o le hydroxyethyl cellulose HEC e le lelei pe a faʻatusatusa i le methyl cellulose ma le hydroxypropyl methyl cellulose, ae o le puipuiga o le malosi colloid e malosi.
Faamoemoega: E masani ona faʻaaogaina e fai ma sui faʻamaʻa, mea puipui, faʻapipiʻi, faʻamautu ma sauniuniga o le latex vali, lacquer, vaitusi.Additives faʻaaogaina i le suauʻu suauʻu, gels, suauu, lotion, mata manino, suppositories ma papamaʻa, faʻaaogaina foi e pei o gels hydrophilic, mea auivi, sauniuniga o le skeleton lagolagoina faʻamalolo sauniuniga, ma e mafai ona faʻaaogaina e avea ma stabilizers i meaʻai.
